Texas RamSan Solid State Storage Appliance and Oracle VM 3.x

Has anyone had success with using a Texas Memory System RamSAN 810 (solid state appliance) and Fiber Channel controllers with Oracle VM 3.x
I believe any Fiber Channel device should work as shared storage, but looking for some extra confirmation that there were no issues before actually buying.
Thanks for any information.

In playing with OVM 3.0 so far, I see that local storage (as the accelerator cards would show up as) is not really appropriate for Production Systems. It appears I can create a Repository on these physical disks and then present them to the VM guest. Then add these cards as my Oracle ASM disks for my "fast" storage, and do the same with the FiberChannel storage for my "slower" disks. Because of the Local Storage used for part of the VM guest, we would not be able to Live Migrate or have High availability I believe. Is this correct? Correct.
If we have the two servers as mentioned above. Could I take the database VM down and move it to the other server (ie Cold Migration)? The local storage (ie the accelerator cards) could physically be moved from one physical host to the other, but I am not sure, since this is virtualized disk, if this would be allowed or how it could be recognized on the other Oracle VM Server. This might be a "dream", but might be something we would like to do if an emergency arose or if more maintenance needed to be done on Server 1. Any comments?You would have to shutdown the VM, migrate it to an unassigned folder, edit the VM, remove the local storage from Server 1, migrate to Server 2 and add the local storage from Server 2. Whether or not this means moving your hardware is up to you.
Does anyone have other solutions to run Solid State disks (approximately 2TB worth) and Oracle VM, running a single guest that runs the database? We have been unable to find iSCSI or FiberChannel enclosures that can handle solid state drives in the 1 to 2 TB range of capacity. So perhaps there are other enclosures out there that can act as Shared Storage that can operate with SSDs. Thank you for any comments and suggestions.I know the Sun storage appliances use hybrid storage, i.e. a mix of SSD/spinning disks, but I don't know the details. Our Exadata machines have 5TB of Flash storage per cell, so I know we have such options.

Solid State Drives, Trim and Oracle

I am having an interesting 'discussion' with my system administrator. He is worried that a database we have running in noarchivelog mode, if moved onto solid state hard drives, will one day start to slow down because of the problem SSDs have about not knowing which blocks can be written to. He is concerned especially that the Oracle Enterprise Linux kernel version does not support the TRIM command which lets an OS get around this problem (see http://en.wikipedia.org/wiki/TRIM)
My counter-argument to him has been that Oracle doesn't delete anything: the datafiles, control files and online redo logs are created once and then simply have their contents changed, over and over. Nothing is ever deleted, so the no-TRIM limitation is not one we would ever run into. I concede that if we were generating archived redo, and then having rman do a 'delete input', there would be a genuine issue. But this particular database is not in archivelog mode so that doesn't apply.
Anyone care to comment on the logic of my case (or lack of it, of course!).

Do not offhand see a flaw in your logic - especially not if the SSD is managed as a single "+raw+" disk via ASM. In this case there is no cooked file system on it that's managed by the o/s. The entire disk (and allocation and free space on it) is managed by ASM.
But then I would also question the use of what still is not yet a fully matured storage technology for databases - and also why the entire storage layer is not looked ito performance?
SDD addresses only a very specific part of the storage layer - and often that (with modern storage arrays and their huge memory buffer caches) is not the biggest limitation in I/O thruput. The PCI technology used (for the physical wire connectivity to the storage system) could be the bottleneck. The wire technology (e.g. fibre channel) could the bottleneck. Etc.
Addressing I/O performance needs a look at the entire storage layer. Not just the disks. (hint - look at what Exadata uses)

I am replacing my existing SATA hard drive to a Solid State hard drive and want to image the drive, is this possible?

I am replacing my existing 320 GB SATA hard drive that clicks and makes weird noises to a Solid State hard drive and want to image the drive, is this possible? I then want to replace the DVD with a secondary large drive for storage.
So I am looking for any "gotchas" that I may be unaware of.
Thanks!

Put the Old drive in an external notebook drive enclosure. Install the SSD in your computer. Boot from your Old drive's Recovery HD:
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Clone Lion/Mountain Lion using Restore Option of Disk Utility
     1. Select Disk Utility from the main menu then press the Continue
         button.
     2. Select the destination volume from the left side list.
     3. Click on the Restore tab in the DU main window.
     4. Select the destination volume from the left side list and drag it
         to the Destination entry field.
     5. Select the source volume from the left side list and drag it to
         the Source entry field.
     6. Double-check you got it right, then click on the Restore button.
Destination means the New SSD. Source means the external Old hard drive.
Set the new Startup Disk to the SSD and restart the computer.
This process clones both your old OS X volume and the Recovery HD volume to the SSD. You can use a similar process to clone the SSD to the new hard drive you will install.

Uh, iFixit and the manufacturer of the upgradeable SSD Flash Storage for the 2010-2011 MBA would respectfully disagree. Yes, the volatile memory is not upgradeable, but the storage SSD (NAND Flash) is as upgradeable as it gets.

Limitation on SQL executing select statement from ADO and Oracle 8.1.7.1 OleDB Driver

Hi,
we are running a query with a big dunamic select statement from VB code using ADO command object. When Execute method is called system hangs and control won't return back to the application. it seems to be that there is some type limitation on Query string length. Please tell us if there is any?
we are running Oracle 8.1.7 Server on Windows 200 Server and connecting from a W2K professional, ADO 2.6 and Oracle OLEDB 8.1.7.1 OLEDB Driver.
Sample code:
Dim rs As ADODB.Recordset
Dim cmd As ADODB.Command
Set cmd = New Command
With cmd
.CommandText = ' some text with more than 2500 characters
.CommandType = adCmdText
Set rs = .Execute
End With
when i debug using VB6 and when .Execute line is called system hangs or return a message method <<somemethod> of <<some class name>> failed error.
Any help is appreciated.
Thanks,
Anil

A stored procedure would only slow you down here if it was poorly written. I suspect you want to use the translate function. I'm cutting & pasting examples from the documentation-- a search at tahiti.oracle.com will give you all the info you'll need.
Examples
The following statement translates a license number. All letters 'ABC...Z' are translated to 'X' and all digits '012 . . . 9' are translated to '9':
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'9999999999XXXXXXXXXXXXXXXXXXXXXXXXXX') "License"
FROM DUAL;
License
9XXX999
The following statement returns a license number with the characters removed and the digits remaining:
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '0123456789')
"Translate example"
FROM DUAL;
Translate example
2229
Also, LIKE '%<string>%' is going to be rather expensive simply because it has to compare the entire string and because it forces full table scans, rather than using indexes. You could speed this sort of query up by using interMedia Text (Oracle Text now in 9i). If you can eliminate one of the '%' options, you could also improve things.
My guess is that your stored procedure is inefficient and that's causing the problem-- 5k rows per table should be pretty trivial.
If you post your query over on the PL/SQL forum, there are better performance tuners than I that might have more hints for you. To get really good advice, though, you'lllikely have to get at least the execution plan for this statement and may need to do some profiling to identify the problem areas.

Managing 250 GB Solid State Hard Drive and 1TB Hard Drive

Just received our new 27" iMac with 2 internal HD, one being the 250 GB SSHD and the other a 1TB HD.
The system came with everything loaded on the SS and when I transferred files from our old G4, they also went on the SSHD, obviously it is getting full.
How do I best manage the 1TB HD and move files and documents over to it? How do I move the iTune files? Can I move the desktop files? etc.
Thanks,

How do I best manage the 1TB HD and move files and documents over to it?
Drag documents over. If you want to move the entire OS X installation, use a program such as Carbon Copy Cloner.
How do I move the iTune files?
Drag it over from the Music item of the Finder's sidebar, launch iTunes with the Option key held down, and point it there. The same method works for iPhoto.
Can I move the desktop files?
Yes.

SSD (Solid State Drive) Upgrades and DV7 4280US

I am posting this as an FYI for anyone who is considering upgrading their DV7 or similar laptop with a SSD.
My experience with this has been somewhat difficult and I am hoping this will help.
I own a DV7-4280US laptop with 6GB of memory, i5 processor, and an 750 GB 5400rpm drive. I decided to put a OZC Vertex 2 120GB drive in it to replace the main drive. I decided to do a fresh install of the factory image directly to the new drive. This failed. I was able to run the HP recovery disks and get all the way through without an error, but was not able to boot. The system stated that there was no valid boot disk. I tried several times with different options and always got the same error message when I tried to boot from the SSD.
The solution for me was to use partition wizard home edition (http://download.cnet.com/Partition-Wizard-Home-Edition/3000-2094_4-10962200.html?tag=mncol;1) and to copy partition #1,2 and 4 over to the new drive (from my old drive in an external enclosure) resizing appropriately so the data all fit on the newer smaller drive. I was careful to make sure each partition was created as a primary partition not a logical one. I also had to make the first partition active as it contained the boot info for Win 7-64bit.
A note about partition size: before I copied the partitions over, I decided to uninstall some of the extra software I did not use that came from HP and a few that I had installed. I also deleted all of my temporary files and did a disk clean up. It is best to not fill your new SSD too quickly and to do as few writes as possible. It is the writing that consumes the drive over time and even if you copied the partition and then uninstalled and cleaned up you will have still consumed some of the life of your drive. I was able to trim my C: drive down to about 30 GB and have a lot of space left in the 111GB of that partition.
My guess is that the problem with the HP restore disks is that they for whatever reason did not set the first partition as active on the SSD. I have not been able to figure out why because they would do this correctly if it were any other type of drive. Maybe this is a bug with that restore program.
I also found that doing a fresh install of Win 7 form a microsoft disk works fine too.
I have been told by OCZ that if I have enough memory (4GB +) that I should set the page file to "No Paging File" in the advanced system settings. This will conserve the SSD as they have a limited number of writes and over time the page file will consume a good portion of it's life.
OCZ and Microsoft both recommended that I run the Windows Experience Index immediately after installing the SSD because it will turn off several prefetch and caching services that you will not need with your new SSD.
I have been super happy with my new SSD and am absolutely convinced that it is the very best upgrade you can do to speed up your system. My windows experience index went from 5.2 to 6.7 the disk is now rated at 7.6. Windows now loads in about 8 seconds and web pages are almost instantaneous. It is well worth the 200 I paid for the drive.

Hey...thanks for the information - I wish my search had come across your post earlier...it would have saved me a couple days of pulling my hair out! I just bought a DV7-7298 (i7, 1T HDD, 12GB RAM, Win8 pre-installed) and similarly wanted to install an SSD (Intel 335 240GB).
The recovery disk option for intalling Win8 on the new drive got me nowhere at all - it would not boot except for once and I had no networking and major software installation issues which forced a reboot sequence and more terror...horribly frustrating and HP was absolutely no help. I had a Windows 7 disk that I was able install on the SSD but no clean Win8 disk. I called Microsoft (who were quite helpful) - they were happy to allow me to download a fresh copy of Win8 with my existing Win8 Product Key...great, I thought...
With some aftermarket software I found the Win8 key which is attached electronically to the BIOS on these new machines - no more Product Key stickers on the bottom of our machines...the problem is that the OEM Key was not accepted by the Windows site to allow me to download the clean Win8 software...argh! In the end, Microsoft helped again by agreeing to mail to me a Win8 install disk (which I though was decent of them)...not a quick solution, however. In looking for solutions, I came across the Microsoft Win8 Pro upgrade offer ($40 until Jan. 31, 2013) - in order to potentially get this done, I decided to spend the $40 and get the upgrade which I downloaded and installed immediately...in the end? Success!! But not quite so fast...I had to install Windows7 on the SSD first in order to run the Win8Pro install which I'd put on the 1T drive that came with the machine - put it in an external drive...it installed without any issues. I downloaded the drivers that Windows missed from the HP website and now have a slick, extremely fast notebook without all the bloatware...so sweet!
It is amazing just how fast these drives work - no regrets at all (except for the wasted time getting it working)...this is a great performance upgrade - if you want a faster machine and quick boot, this has got to be the best bang for the $! With this DV7, I can still have the 1T drive in the second bay (battery power isn't a problem for me) so a lot of my data will be going there with programs on the SSD. If you're considering this upgrade - great - do it for sure! But do yourself a favour and don't waste time with the HP recovery disks...they just don't work for this upgrade...find someone with a clean Windows disk (XP, Vista (ugh2), 7 or 8) and install your OS that way. If you have the UEFI BIOS Product Key set-up - it should activate itself (Win8).
Best of luck - you'll love the results!

I7 Computer Windows8, 4GB and a solid state drive or one with Windows7,12GB of RAM and a 7200 HD

Hi. I will be upgrading my computer. My underlying need is portability and thus I am looking at ultrabooks. Of the machines that I currently like that I have currently seen, my choice seems to be Windows 8 but have limited RAM (4GB which is'nt upgradable) and limitied on board solid state storage or to give up the touch screen of Windows 8 and have a hard drive with more on board storage and gain more RAM (12 GB). Any thoughts on which configuration would work better with CS6 for photo viewing/editing as far as speed of loading and saving? Is there enough power within the 4GB configuration that there wouldn't be a noticable difference between the two? Also, the same for movie editing within CS6?
Thanks for any thoughts.

Brocfeld in general I would recommend getting a big enough hard drive to contain both your operating system and your installed applications with room to spare. Many times users choose a small SSD and then try to install the apps on a standard harddrive. This basically negates most of the benefits of using an SSD in the first place.
Beyond that you may want to post in the product specific forums regarding the best setup to utilize the Adobe Creative applications you commonly use.

Adding a solid state hard drive to a Mac Pro 3,1

I have two hard drives in my Mac Pro 3,1. I want to add a solid state hard drive and upgrade Yosemite to it. I will eventually use my existing drive as extra storage. Does anyone know if this model of Mac Pro can support SSD drive? Also, can I mix and match normal hard drives with SSD drives? I know I will also need an adapter since SSD's are 2.5 inch. The one I am thinking about getting is the Kingston SSDNow V300 Series SV300S37A/240G 2.5" 240GB SATA III Internal Solid State Drive (SSD). Any feedback that can confirm or deny compatibility would be appreciated.
Thanks,

I have Mac Pro (4.1 2009 model) and I have Samsung SSD 840 EVO 500GB. There is an issue you you want to run Yosemite. That drive requires that TRIM is enabled otherwise the perforamnce goes down. There is a Trim Enabler that you can get but but default Yosemite rejects it and disables it so you end up with a driver with TRIM not eanbled. There is a hack that allows you to get it working again but it has some security implications.
Just be aware of it.

Solid state vs Disk Dr

Does anyone know which Creative MP3 players use Solid State storage media rather than Disk Dri'ves?I need a unit that uses Solid State memory and has a capacity of about 8-0GB. I've heard that the Zen V plus is this kind of device, can anyone confirm this?Thanks!?

The Zen V Plus models are all flash memory (no moving parts) storage devices. Including the Zen V Plus 8gb unit.

Disk Drive Full. Whats the best way to transfer operating system to larger non solid state hard drive .

Heres the Lowdown,
I have a Desktop that has a 250 G Solid state hard drive , and a secondary 750 G Hard drive.
My OS is installed on the solid state , and also a lot of my audio software which needs to also be on the same disk drive as the operating system ;
Problem is I've run out of room and continually get DISK FULL error messages , which stop me from doing any real time audio tracking and recording.
I've backed up all files to an airport drive ( I'm a bit paranoid about losing vital info) .
Is there a way to reinstall the OS onto the second larger drive and just transfer the remaining software across
Will I have to reinstall all previous versions of software if I do this?
Will The processing slow down if the OS is run on the Standard drive rather than the Solid State drive ?
Last time I tried to clear some space on the OS drive I accidentally deleted vital information, so I wanna make sure I do this properly.
Any advice would be much appreciated.

Carbon Copy Cloner (1 Month Demo with full capabilities). Because CCC also has the ability to transfer your Recovery Partition
SuperDuper (Free for a full clone). Recovery partition will not be transferred
Applications -> Utilities -> Disk Utility -> Restore (from SSD to 750 hard disk). Recovery partition will not be transferred.
Or install the OS on the 750 hard disk (with will install a recovery partition), then use migration assistant to move your files over. Or you could then use one of the above utilities to overwrite the just installed OS without messing with the recovery partition.

Solid state memory

Can I upgrade a macbook to use solid state memory. And if I can how would i go about doing that?

I believe you should be able to. I would check ifixit.com for some excellent disassembly guides.

No room on solid state drive?

I have a 2011 27 inch iMac. 3.4 GHz. I have a 250Gb solid state (startup) drive, and 1 terabyte Hard drive. The solid state drive is almost full and I don't know why, or how to clear it and put unnecessary data onto the Hard drive where it belongs. Any advice? Thanks.

Drop and Drag the larger files/libraries to the External Drive and then point the Apps that need them to their location on the Ext Drive, such as iPhotos Library and iTunes Library. I have always done this and it frees up my SSD greatly for faster operation.
Cheers

Don,
I know you and your company has done lot of research on (RamSan+Oracle RAC), but it will be nice if you can comment on (FusionIO+RAC) solution. I know no one has used it so far, but I think it is viable, so what do you think?
The reason why I think FusionIO is a good solution for small DBs because it's not a Flash Drive and it costs less than the other SSD solutions available in the market. Also you do not want to buy SAN for small DBs (<250 GB).
But I am too sure about the actual configuration at this point like - gigabit vs 10 gigi NIC, type of interconnect, Fiber Channel, etc.
So I would really appreciate if you can provide some insight.
Thanks in advance....
