Hard drive configuration with Promise Raid controller

I plan on running two 30 gig 75GXP drives on the Promise controller in Raid-0 mode.  I also have a 60 gig WD drive that I use for backups and for initial installation.  During installation, I put the Win98SE setup files and all the drivers, apps, backup data, etc. on the WD drive and do a clean install from there.  
My current (old) board is an Abit KT7-R with the Highpoint raid controller.  Using the Highpoint controller, I am able to put the WD drive as a slave device and the controller treats it as a normal IDE drive.  I'm moving to the 845 Ultra ARU.  From what I've read, if you put a single drive on the Promise controller, it tries to set it up as a Raid drive?  I don't want to risk losing my backup data on the WD drive to some attempt by the Promise controller to "raid" my single drive.  So, where is the best place to put my WD drive so that I can install my system from it?  I'm thinking about putting it as Master on IDE2.  I normally run my CD as Master on IDE1.  Once the installation is complete, I will remove the installation files from the WD drive and use it exclusively for backups.  I have the WD drive in a Vantec EZ-Swap rack, and I normally keep it powered off unless doing a backup.
So, the plan is to create the Raid-0 array, Fdisk and format the array, and then load Windows from the WD drive, followed by all my applications.  Is Master on IDE-2 the best solution for the WD drive?  

hi
not very clued up on raid but it sounds right
if the wd drive is on its own on that ide do not jumper
as master you have to have no jumpers if all alone

  • Looking to expand hard drive configuration into multiple Raid Drives...how

    I'm want to put either two or three new drives into my new mac pro. I'll be using them for video editing
    .....how hard is it (or wise) to link them in a SCSI configuration? How would I go about doing this?
    ....I'm not anywhere near a "gear guy" but I'm not stupid either (at least that's what my mom told me......heh)
    I was told that an "enterprise class" is the way to go on the type of hard drive, so I'm planning on getting that type of drive.
    Thanks for any help in advance.

    No one almost uses SCSI - and I was a die-hard. Even SAS isn't worth the trouble generally.
    A fast boot drive is helpful and SSDs or 10K WD SATA VelociRaptor (150-300-600GB capacity). Most just go for 1-2TB drives.
    Software RAID using Apple Disk Utility. Backups, 2-3 sets.
    With no real experience with RAID or setting things up then you are left with experimenting and testing what you know and can do and keeping it simple at first.
    And most people do use 4 drive bays and then externals for backup and more.
    SCSI generally means ATTO or LSI or others with a large up front cost in controller, cables and disk drives, that part hasn't changed much in 10 yrs. but SATA II/III has more options today.

    My motherboard has 6 x 3Gb/s and 2 x 6Gb/s SATA ports and has an onboard RAID, using an Intel ICH10R Southbridge controller.  The motherboard also has USB 3.0.  I have a DVD drive using one of the SATA ports.
    Although I understand the principal of RAID I’ve never used it before.  So, what would be the best way of improving performance?
    I presume that as all my drives currently have data on them I’ll have to copy this data to another drive before formatting them and then creating the RAID drive.
    I look forward to hearing your thoughts and suggestions.
    Many thanks.

    Thanks Harm.  I've gone through your suggestions.
    As my computer has to function for several other tasks in addition to video editing, I realise that I will have to compromise somewhat on the performance to make sure that it's still useable for other things.
    Using Black Vipers tips I've reduced the processes running from 100+ to 89.
    Indexing and compression turned off for all drives except Storage, which isn't used for video related tasks.  Although it wouldn't surprise me to learn that having any indexing turned on will have a degree of drain on resources.
    Discs all defragged.
    Media Cache cleared.
    Any further advice on how to optimise the hard drives would be very much appreciated.

  • Best hard drive configuration with two drives

    Hello,
    I am considering adding a second hard drive to my blue and white g3. It currently has the original Quantum 12GB Ultra ATA/33 hard disk (ATA 33 is capable of about 33 MB/s).
    I would install a FirmTek SeriTek/1S2 card (2 Internal SATA Ports) and then I would add a 160 GIG or a 250 GIG Maxtor hard drive. The hard drive would probably be a Maxtor DiamondMax 10, or a Maxtor MaXLine III. I will also consider the Seagate Barracuda 7200.8 as well. I think all these drives are 7200RPM.
    The final result will be that my G3 will have two hard drives, the original 12GB Ultra ATA/33 and also a 160 GIG 7200RPM drive.
    What is the best way for me to manage my data with this setup?
    What exactly is a "boot volume" or a "boot drive"? Are there boot volume strategies than enable your computer to be faster and more efficient? Do I need a boot volume and if so, on which drive should I create a boot volume?
    I am currently using OS9 however I will be moving to OS10.1.5 soon and then perhaps to OS 10.4 panther later.
    Should I put the OS on the original 12GB Ultra ATA/33 or on the new 160 GIG 7200RPM drive?
    How about the applications? Which drive should they be stored on?
    My main programs are the Adobe Creative Suite programs (Photoshop and Illustrator) as well as Macromedia Dreamweaver.
    If my OS and apps are more than 12 GIGS and they are unable to fit on the 12GIG drive together, should I put the OS and apps on the larger 160 GIG drive and not use the 12GIG drive at all? Or does it make more sense to use the 12 GIG drive for just the OS and then the 160GIG drive for the apps and everything else (such as my stock photo collection)? Should I partition the 160 GIG drive?
    Thank you for any advice.
    PS Does any one know of a place to buy a SATA drive such as a Maxtor MaXLine III for a good price? Are Maxtor DiamondMax 10 as reliable as Maxtor MaXLine III? Is Maxtor MaXLine III worth the cost difference? Or would anyone recommend any other good brand of a hard drive? I will need about 160 GIGs or maybe 250. Thank you.

    ...Should I partition the 250 GIG drive as mentioned in my original post (system and apps in one partition and data in another all on the same drive)? Or is it OK to leave it as one large volume?...
    Partitioning the drive "half-and-half" would probably be a good idea.
    ...What utility should I use to partition it if I decide to partition?...
    Disk Utility can do that, just make sure to do the partitioning when you first install the drive.
    ... I will also need a good ATA card that will work with both OS9 and OS10- any recommendations?...
    I have one of these and it has been working well.
    It is $60, which is the lowest price I know of for a Mac card.
    http://www.newegg.com/Product/Product.asp?Item=N82E16816123110
    ...could anyone recommend a good ATA 250 GIG hard drive (PATA - not SATA) for the purpose of graphic design applications (photoshop and illustrator)?...
    Any name brand drive should be fine (Seagate, Western Digital, Maxtor, etc.).
    Stay away from PC-branded drives though (Dell, etc.),
    some don't work on Macs.
    Some drives in the 250GB size range have 16MB of cache, that and 7200RPM would have the best performance, but might be overkill considering the PCI speed bug (it wouldn't hurt though).
    Note: Most regular ATA cards are 33MHz only.

  • Upgrade hard drive size with mirrored RAID

    First of all thanks for your help.
    I have a G5 XServe with (3) 250GB Drives
    (1) drive is for the OS .... great perfect no change needed.
    The other to drives are mirrored to eath other and hold 240GB worth of work.
    I would like to buy (2) 500GB Drives to replace the 250GB Drives.
    What is the easiest way to do this?
    Idea 1) Will this work???
    Break the raid by ejecting one of drives.
    Put in one new 500GB Drive.
    Copy all data from 250GB to 500GB
    Eject 250GB drive
    Put in other 500GB drive.
    Re-set up Mirror with out losing data?
    Idea 2)
    Copy it all to an external drive....
    Install new 500GB drives
    Set up Mirror
    Copy data back.
    Hmmm... either way I'll have to set up all of my share points?
    Thanks for helping me think this through.

    Either path will work.
    The first should be faster (the data only needs to be copied one), the second gives you a spare/backup copy of the data which might come in handy later.
    Sharepoints are referenced by path, so as long as the new 500GB mirror is mounted in the same place as the existing 250GB mirror, your sharepoints should remain intact.

  • Howto use onboard Promise Raid Controller pdc20265 on 694D PRO AR Ver1

    Currently I'm running Win2k on my MSI 694D Pro AR Ver 1.0 board with Bios version W6321VMS.310 and the included Fasttrack-Family Win2k Raid-Controller driver for my Promise Raid Controller pdc20265 with lite bios.
    Due to software updates I'm now absolutely required to switch to Windows XP Prof. However this is the cause for my inquiry:
    I downloaded and installed the latest available Bios version W6321VMS.370 from MSI site.
    On installation of XP I tried to include the pdc20265 Fasttrack raid driver from MSI site to get access to my HD's. However WinXP couldn't find any HD's. Remark: XP with SP1 and VIA 4in1443v.exe installed.
    So I repeated this procedure with the original drivers Fasttrack family and pdc202065 which were attached on floppy. Unfortunately no success as well.
    Then I have put the HD on the Ultra66 channel and installed XP first without raid and ultra 100 support.
    Later I re-enabled the on-board promise device in bios and unfortunately WinXP didn't recoginze the device by itself. So I provided the latest pdc20265 driver from MSI site. XP complained that the driver is not digitally signed. After reboot the promise device reported an error under WinXP.
    I repeated this procedure with the original drivers Fasttrack family and pdc202065 which were attached on floppy. Unfortunately no success as well.
    Why MSI-Site says this pdc20265 driver supports WinXP if there are only the Win2k and WinME,98... drivers included?
    Currently I can't use the promise device at all under WinXP. This means even I don't have an Ultra 100 controler available.
    Has anyone an idea how to install HD's on WinXP with the corresponding promise raid drivers for my pdc20265 onboard chipset?
    I'd really appreciate your help!

    Some of the suggestions I don't understand quite well. Please could you explain further:
    > remove the other two drives leaving the raid pair
    > and cd only
    >
    > put raid 2nd in boot order
    What do you mean with that?
    > reboot press the key you need to get in to raid bios
    > create the array and make it bootable
    array is already created (Note: there is important data on it, can't recreate it! Only Segate 80GB is free and empty)
    I don't want to boot from raid.
    >
    > now boot to cd to install,right at beginning it will say
    > press f6 to install mass storage drive you need the
    > driver on floppy to install it
    I already tried the XP-Install routine to specify additional mass storage drivers. (Note: 1 single 80GB Drive was attached)  Which are the suitable ones? As mentioned I tried the following:
    1. Attached floppy 'Fasttrack family drivers'
    Result: Message: Driver is for Win2k only. Not a single  Harddrive shows for installing XP.
    2. Attached Floppy (Promise Ultra 100 lite, 256 only)
    Result: Driver is for Win2k only. Installation procedure hangs.
    3. Driver from MSI-Site for pdc20265. Same as 2.
    4. Extracting via4in1 drivers and putting WinXPIDE drivers on floppy:
    Result: Installation routine doesn't recoginze drivers on floppy.

    Which is the right driver for WinXP to specify for mass storage device at WinXP installation?

  • Hard Drive configuration for speed

    I've got a question regarding the best hard drive configuration for my mac pro. I'm looking to increase the boot speed, application load speed and particularly the speed with which hard drive intensive photoshop processes complete. Right now I'm just using some normal SATA II drives. I'd appreciate it if you could give me some feedback on the various options I am currently considering.
    -2x 64GB SSD in a RAID 0 for OS X and applications with some large SATA drives for storage
    -4x 300GB VelociRaptor 10k RPM SATA HDD in a RAID 0
    -2x 147GB SAS 15k RPM HDD in RAID 0 with some large SATA drives for storage
    I am particularly in the dark about the controllers I'd use for each solution. Clearly, I would absolutely require a PCIe card for the SAS drives, but would there be a marked advantage to using a hardware RAID card for the SATA drives over the software RAID in OS X? Also, how easy is it to get the mac pro to boot off drives connected to a controller card rather than the standard setup? And lastly, if there is good reason to use a card, are there any in particular that you would recommend?
    Thanks a lot!

    2. No. Do not make two partitions unless you do not plan to use Boot Camp Assistant to install Windows on that partition. If you plan to create a Boot Camp partition then you must partition the drive as one Mac OS X volume. Boot Camp Assistant will then create the Windows volume.
    3. This drive must be repartitioned and reformatted as follows:
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Set the number of partitions from the drop down menu to two. Use the graphic resizer to set the desired sizes for each volume as you want. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the first volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    7. Select the second volume you created and repeat Steps 4-6.
    4. Now here I don't know what you think is your best option. You can buy any two hard drives you want. The ones I identified were only an example of what you could purchase for under $300. There are others, slightly more expensive, that would work, and you would still be under your $300 budget. The Samsung drives are good drives and reasonably priced, but they are just one of several alternatives. You should do some checking on your own before making your decision. I'm just giving some guidance, not trying to tell you what you should do. I've provided three sites where you can read reviews and benchmarks before you decide. You need to "own" your decision.
    As for how you configure these two drives that's a secondary issue. I would recommend using them for backup. Two possible arrangements are a Mirrored or a Striped RAID array. A mirrored RAID array would create one volume that has a 1 TB capacity. Everything saved to that volume is essentially saved twice - once on one drive then a copy is mirrored to the other drive. This is not what you described in your Item 4. That's not how it works. Anything saved to the mirrored RAID array is saved the way I described it just above. It makes no difference where the files come from.
    Now you can use the mirrored RAID array as a Time Machine backup drive if you want, but then you should not use it for other data storage. You would need the entire capacity as backup for both of the 500 GB drives you currently have. A mirrored RAID provides some data redundancy by having a copy of everything one each drive. Thus, if one drive fails the other drive still functions and your data backup is intact. Mirrored RAIDs are generally no faster than an individual drive that makes up the array.
    The second suggestion was to make a Striped RAID array. This type of array produces one volume that is twice the size of the the two drives that make up the array. Thus, you would have a single volume that is 2 TBs in size. You can use this volume for your Time Machine backups also. Striped RAIDs do not provide any data redundancy. If one drive fails all the data stored on the RAID will be lost. However, Striped RAIDs are nearly twice as fast as either drive that makes up the array. This would give you very fast storage and backup.
    You could also just leave the two drives to operate independently. Use on for Time Machine backups, use the other for more storage space.
    Other possibilities abound. It's pretty much up to you to decide what will fit best into your needs today and in the future. Don't feel obliged to do what one person tells you. Five different users on the Discussions will give five different opinions.
    I suggest you educate yourself a bit on backup and restore by reading the FAQ about backup and restore at The XLab FAQs.
    Following is more information on RAIDs:

    Hardware or Software RAID?
    RAID Hardware Vs RAID Software - What is your best option?
    RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
    RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
    Pros and cons
    Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
    For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?
    OS X has software for creating RAIDs by using Disk Utility. Open Disk Utility and select DU Help from the Help menu. Search for "raid" without quotes. You will find information on how to set up mirrored and striped RAIDs using Disk Utility.

  • Internal hard drive issue with Mac Pro

    I work for two office that share information through a VPN. Each office has one Mac Pro being used as a server for data storage. The Pros have four internal hard drives (1TB each).
    Hard drives in the Pro for OFFICE 1 were configured like so:
    HD1 - OS/Boot drive
    HD2 - Time Machine backup of HD1/DATA1/DATA2
    DATA1 - Data storage
    DATA2 - Data storage
    Three weeks ago: Time Machine could not find HD2 and could not backup. I rebooted the machine and HD2 reappeared. However, after the reboot, DATA1 did not mount. I was unable to find DATA1 in Disk Utility. However, the drive could be accessed by all other Macs on the network. This machine was taken to the local Apple Store and we were told that HD2 was a bad drive and need to be replaced. We opted not to replaced the drive at this time and turned Time Machine backups off. We haven't had any problems with DATA1 since. (NOTE: During the weeks prior, the client machines intermittently lost connection with DATA1 and would have to reconnect)
    Last week: OFFICE 2 - Mac Pro hard drives configured the same as OFFICE 1; however, HD2 was not used for TM backups. TM was turned on and set to backup HD1/DATA1/DATA2 to HD2 (exactly like OFFICE 1). The next day, TM could not find HD2 and backups stopped running. I rebooted the machine, HD2 reappeared, but we did not restart the TM backups.
    Today: OFFICE 2 client machines have experienced intermittent disconnecting of DATA1.
    I wasn't extremely concerned with the situation at OFFICE 1 as these Pros are almost five years old and in constant use. We plan on purchasing an external drive for the TM backups. HOWEVER, with a similar situation now being experienced in OFFICE 2, I am perplexed.
    Could both machine be experiencing hard drive failures weeks apart? They were both purchased and installed at the same time.
    Is there a known issue with TM and internal drives?
    One difference between the two machines: OFFICE 1 is running OS X 10.8.5; OFFICE 2 runs 10.6.8
    Any suggestions/help is appreciated. Thanks!

    Relying on TimeMachine has some issues, along with only having one, I use at least two swapping TimeMachine so that they rotate AND I clone every drive (volume actually) so I can swap drives if need be, especially useful for t he system but good for any drive.
    Power issues in t he buildings?
    There are some programs that will scan for and report and./or attempt to reassign a failing sector ("fail" is qualitative, is 10 write failures a fail? then the 9th is not but it is a "weak sector.") Some run in the background.
    Mirror can be 2 or 3 ( I prefer 3, that way if one fails I STILL have a mirror array in place) where any failure is not acceptable, AND where the array data is backed up usually - less important  when using a three-drive configurations.
    How old, when last initialized (zero), and is it showing spare blocks being used? that last is the most indicative of failed drive.
    Rare but a bad SATA cable or power (seeing how the cables are tucked away) is only way generally for multiple failures in same drive bay or computer. Note: early on in 2006-7 there were reports of some customers having motherboard and trouble with a drive bay , and t he problems showed up early.
    Often though it is NVRAM or SMC related issue trigged by something else, a USB cable or device that is faulty, even a PCIe controller that is the culprit. And replacing cable, keyboard, device, and resetting SMC and NVRAM (often NVRAM needed to be done multiple times, but never keep resetting SMC) - unplugged and when you connect back up, do not install anything other than system, keyboard and mouse and see if that helps.
    With a drive, likely the drive in 85% or more, is fine, but the directory is not, or it needs to be erased to rebuild all the system partitions.
    1TB is small for TimeMachine. 350% of the amount of data, and always have free space for a full backup set of all the data. T.M. will try and prefers to automatically backup any and everything plugged in and connected, rather than my preference which is ASK FIRST to add a drive to TM backup set, otherwise leave it out. 600GB of data and system would mean 2.5TB drive, maybe 2TB minimum.

    6.)))<BONUS Drive> I am planning on running some tests to see how much max RAM I can use, and whatever is not being used, I am hoping to hear some positive feedback on making a RAMdisk or a couple of them.   (I have seen unbelievable benchmarks for them.)  If it is recommended, could I use a RAMdisk for {2.- Media Cache & Preview} or should I just use it for Pagefiles and other Caches and temporary files? (or forgo it altogether?)
    I know this is a loaded question, and I am open to other suggestions that might include buying ~$300 in additional drives if it will increase speed and performance tremendously.
    Thank you all for reading & I am really looking foward to learning from your knowledge and experience in this area!

    Mike,
    Check. SATA 6G port. Add a static pagefile of 1 or 2 GB here.
    Check. SATA 6G port.
    Check. SATA 3G port. No sense in raiding this and doubling the risk of data loss. Even a 25 GB export will only need ± 3 minutes or less to write.The time for export is spent on encoding, not on writing. Why take the risk and spend the money for a potential 80 - 90 second gain on each export of 25 GB? How often do you do that?
    Check. SATA 6G ports on Marvell. Make regular backups of your projects.
    Check. SATA 3G port. I would be very hesitant to raid0 the original media because of the risk of data loss.The X79 platform is designed for dedicated raid controllers and parity raids. If you need more speed, go that route.
    Forget about it. It is not practical. Windows does not allow booting without a pagefile, so it will always create a dynamic pagefile on C: if it does not find it. With 64 GB memory the pagefile will hardly be used if at all. A static pagefile of 1 GB is enough. Everytime you turn off your machine, the RAM disk gets erased and upon booting must be newly created. That means that the media cache must be newly created, indexing, conforming and creation of peakfiles must be done every time you open a project. That time lost far outweighs the potential gain of a faster RAM disk.

  • Which is the optimal hard drive configuration for Logic Pro ?

    hello people
    i would like to ask your advices about possible hard drive configurations for Logic Pro
    I have a Mac Pro and thinking to buy 4 x 500GB drives .
    there are several combinations in my mind to configure , but first of all i would like to ask which is the best for an optimal system for Logic Pro
    model 1 :
    1 stripe Raid 0 array drive for ''System'' (500+500 = 1000)
    1 stripe Raid 0 array drive for ''recording + sound banks'' (500 + 500 = 1000)
    which means to using 4 hard drives as 2 drives
    model 2 :
    1 stripe Raid 0 array drive for ''System'' (500+500 = 1000)
    1 Single drive for Sound banks (500)
    1 Single drive for Recording (500)
    which means to using 4 hard drives as 3 drives
    Or , it is more healthy to use the drives as single , without raid , stripe sets but with its own capacity instead of combining .
    and also if someone has an idea regarding to compare of Seagate and Westerndigital drives (which is the best for audio recording) , would be really helpfull
    I am kinda rookie for these subjects :/
    thanks in advance

    heelo blayzay
    thanks for the reply and assistance.
    1) how can i create a back up set for the 4th HD to be make back up of the 2nd and 3rd HD
    2) what about to make 1st HD for system and 2nd3rd4th (1.5TB) for audio recording, and an external drive for backups ?
    For the back ups , is there a special process for the backing up HD (internal or external) ? Or should i just need a Clone software to make the back up
    thank you again.

  • Tiered Storage Spaces with LSI RAID Controller 9260-8i (no JBOD) - Performance Drop

    Hello
    I have a Lab-Server with a LSI-Raid-Controller 9260-8i and 2x 256GB SSDs / 6x 600GB HDDs. First I configured the LSI-Raid-Controller with a RAID 1 (2x 600GB HDD) and installed
    Windows Server 2012 R2 with Hyper-V Role on this RAID 1. This works just fine. Then I configured the LSI-Raid-Controller with additional 6x "Raid 0 Drive Groups" where each Drive Group has one single physical drive
    in it. And then I created 6 virtual drives out of these 6 Drive Groups. So far so good: my Windows Server 2012 R2 now sees 6 new Harddrives (4x 600GB HDD and 2x 256GB SSD). I then created a Storage Pool out of these 6 drives (with PowerShell /
    assign MediaType SSD/HDD) and on top of the Storage Pool a "Tiered Storage Space" with Mirror Layout (2x 256GB SSDs mirrored and 2x2x 600GBs  HDD mirrored). This gives me a Tiered Storage Space of about 1.3TB. On this Storage
    Space I created a Virtual Drive of 1.3TB capacity. Success!! It seems to work fine.... Even I do not have a Storage-Controller supporting JBOD directly, I was able to create a Tiered Storage Space!!
    Now where's the problem? Fine-Tuning the LSI-Raid-Controller Settings and the resulting
    Disk Performance....
    1) LSI-Raid-Controller: Virtual Drive Properties: What should I choose? Read Policy (Ahead or no) / Write Policy (Write Back with BBU or Write Through) / IO Policy (Direct IO or cached IO) / Disk Cache Policy (enable or disabled or unchanged)
    / Stripe Size (256 KB or ??). Do these settings conflict with the Windows Server Storage Space Layout?
    2) Windows Server Disk Management (under "Disk XY"):  Write Cache Policy? (activate Write Cache on this Device) 
    3) Windows Server Device Manager (under "Drives" - Microsoft Storage Space Device):  Write Cache Policy? (activate Write Cache on this Device)
    4) Performance - Results with Crystal Disk Mark: the inital Results after setting up the Storage were quite good (Seq R: 550 MB/s and W: 590 MB/s //  512K R: 490MB/s and W: 618 MB/s // 4K R: 18MB/s and W: 37 MB/s  //  4KQD32
    R:270 MB/s and W:37 MB/S) But 2 months later the values dropped to: Seq R: 290 MB/s and W: 170 MB/s //  512K R: 120MB/s and W: 239 MB/s // 4K R: 1.5MB/s and W: 31 MB/s  //  4KQD32 R: 9 MB/s and W: 71 MB/S). Huge loss of performance
    - SSD full? 
    5) Since this is a Hyper-V Server I put some VMs on it. The Performance within the VMs has also dropped accordingly. Are there any
    best practices when placing VHDX-Files on  a Tired Storage Space? I could of course assign one or two VHDX-Files directly to the SSD Tier, but actually I don't want that because that would use too much SSD-Space.
    Any Experts on this Subject?
    Mark

    Hi Mark,
    For the settings of the Raid Controller, it is better to confirm with manufacturer for detailed information. As you said these settings will affect with storage space settings.
    From the description you set the 6 disks as 6 RAID0 groups. Is it supported to leave these disks as JBOD and directly add them into a storage space? If Raid settings will affect storage space performance, this could help us avoiding the RAID settings. 
    As data is already written onto the virtual disk, we may not available to recreate it. You could have a try with following PowerShell cmdlet to see if it will work better after optimize. 
    Optimize-Volume -DriveLetter X -TierOptimize

  • StorEge A1000 + PC (with Mylex960 Raid Controller)

    PC = PIII / 800EB / 256MB / 20GB
    Raid card = Mylex DAC960
    StorEdge = A1000 with 3 x 18Gb drives loaded.
    Wehn Mylex scans for a new scsi device, Storedge A1000 can't be traced/probed. I tried this with HP scsi box and were able to probe the external devices but for Sun Storedge A1000 it was not successfull.
    Any advise on how I can probe/trace this external device (Storedge A1000).
    I am planning also to install solaris 10 (x86) and hopefully Solaris could detect the external storage (series of drives) at the application level. (cross finger)
    For your advise Gurus.

    Can you describe the features and specifications of that SCSI card ?
    The A1000 array has a High-Voltage-Differential interface.
    (See its link in the Sun System Handbook)
    HVD is not common in the PeeCee universe.
    The array already has a RAID controller in its chassis,
    and will not work with a RAID controller SCSI card.
    Any attempts to use a LVD card or a S/E card will just not work, either.
    It would be invisible to the SCSI chain.
    ... then, additionally, you're going to need some sort of RAID control software
    to administer the A1000 and its internal RAID controller.
    if you do eventually get a compatible HBA, you also need to be aware
    that functional support for the array was specifically dropped from Solaris 10.
    You'd need to run Sol8 or Sol9 with RM6 software, and I cannot remember
    whether RM6 was ever ported to x86 Solaris.
    I fear you're just going to be out of luck,
    and may need to get rid of the array (e.g. Ebay ?).

  • Hard drive configuration is not set to factory default. Refurbished Acer Iconia W3-810

    This tablet was purchased refurbished.  As soon as I got it, I went to create my backup and message is "Hard drive configuration is not set to the factory default.  Backup aborted.  I had already sent it in once to the seller for repair services and it was sent back not repaired.  They now say I can send it in again but seems a waste of time.  I called Acer and they said I would need to purchase the recovery disk which should have already been provided to me.  It does have a valid SNID number.  I checked.   If there is anyone else who came up against this problem, I would love to know what you did to resolve it.  Second problem.  Large font had been created where is overscans the entire page so reading the Control Panel is impossible.  The warranty dept created a new user account with new settings as they were unable to fix the font problem so they ignored it.  This is another reason I wanted to do a factory reset.  Hoping Acer will be kind enough to just send me the disk.   I've learned alot about refurbished products.  Never again.   

     Hard drive configuration is not set to factory default (I had this problem but mine was caused  by some third party partitioning software easeus. I am not pretty entirely sure what was your cause for the error, but I believe this workaround can be useful, even to some of the users)  I learnt a tough lesson and I am now careful on what third party soft wares one must use especially for partitioning related events using windows 8 GPT structure. This article specifically relates to windows 8 (which I was using) although similar steps may work as well in windows 7 Points note:Most newer windows devices now use the GPT partitioning system compared to the traditional MBR system.It can be very difficult to reinstall windows on a partition with GPT format.One must be careful on what 3rd party portioning tools they use. It is not recommend to use some 3rd party tools to resize partitions as these may mess the hard drive configuration in such a way that it will be very difficult to restore to factory settings (especially for devices pre-loaded with OEM-Windows 8)It is recommended to use the in-built Disk management utility to shrink/resize partitions.First and foremost, it is recommended to use system file scanner to check any files that may be corrupted (and most of these are normally fixed by sfc)Press Windows key + X, select ‘Command prompt (Admin)’. Enter the following command “sfc /scannow” (without quotes) and the system will start scanning the system. Wait until it finishes.Now we will proceed to the main fix; here are the set of steps I performed,Run CMD (Admin)Type diskpartType list diskDisk 0 Online 465 GB 19 GB * (an example of how the disk will present)
    Disk 1 Online 22 GB 0 B * Select diskDISKPART> select disk 0 list partitionDISKPART> list partition (Note you see recovery partitions flagged as OEM) So what we do is to set the id according to the GUID (Global Unique Identifier) system.Selected every partition with a OEM typeI changed their ID's to DE94BBA4-06D1-4D40-A16A-BFD50179D6AC (see below)Partition 1 OEM 1000 MB 1024 KB

Now you can try system refresh/reinstall to factory settings (or create a recovery media)*In my case and others I researched on internet, it turns EASEUS partition master was the culprit, please don’t use that software if you don’t know what you are doing. (With all respect to EASEUS) I think this tool is still not configured well to work with the GPT partition format.
