Mixing JBOD and Raid 5

Has anyone set up Raid 5 & JBOD volumes on XServe RAID? We have a Raid 5 volume on one controller and would like to set up JBOD on the second controller so that we can fill these disks with backups to the Raid 5 data and take them offsite for disaster recovery. So I have several questions:
1. Can you have Raid 5 & JBOD on the same XServe RAID?
2. If they can be on separate controllers can then also be on the same controller?
3. Is there any problem or special procedure for ejecting these JBOD drives so we can take them offsite?
4. If we have 3 drives to use as JBOD for backup, should we have each one formatted as its own JBOD unit and put them in one at a time for effective offsite backup? Could we put them all in at once and fill them each at a time and remove as they fill? Should they be one volume or three?
Thanks for any thoughts on this. The plan is to use these drives for backup now and down the line convert them to additional Raid space.

Hi David,
1) Yes.
2) Yes.
3) I don't believe so -- but I haven't tested it yet. I'd imagine "ejecting" them from the host and them removing them would be fine -- of course be careful not to remove the wrong disk
4) If you have 3 drives in JBOD, it has to be 3 volumes. Unless you're suggesting mirroring on the RAID (which would not be JBOD, it would be RAID 1), or mirroring on the host (which is a software RAID 1 mirror). JBOD is "just a bunch of disks" -- there is no RAID involved at all.

Overclocking and RAID, do they mix???

What board do you have? It makes a difference in this case. For example, the Via K8T800 based boards do not have PCI/AGP locks, so raising the FSB overclocks all the other components as well, including the HDD controller, and it has been observed that for these boards, RAID arrays will become unstable at FSB settings above about 225 MHz, at most, so overclocking and RAID do not really gotogether on these boards. The nforce3 based boards, on the other hand, should have PCI/AGP locks, though I think (but I'm not sure) that you have to explicitly enable them in BIOS, and I've seen some threads questioning whether or not they actually work, so again the board might have problems with high FSB settings, although I'm pretty sure an nforce3 board would have a working lock and thus be able to overclock with a RAID array defined. Finally, if you have a nforce4 based board, it should definately have a functional lock on it, and it should handle the RAID just fine when overclocking.

Pros and cons to JBOD/N-RAID setup on MacBook Pro with two internal SSDs

First, to clarify, in this case, I mean the term "JBOD/N-RAID" to refer to a concatenated or spanning set of drives as supported by OS X and Disk Utility.
I've got an original Apple-installed 120GB 3G (3Gb/s) SSD which I'll be moving into the optical bay using an OWC "Data Doubler" and swapping a new 240GB OWC Mercury Electra 6G (6Gb/s) SSD into the main drive bay.
My goal is to avoid having two separate volumes.
Understand that a RAID 0 array would essentially only perform as well as the slowest drive in the array (the 3G SSD in this case), if it would even work at all given the two drives are not identical in make and capacity.
I've read that a JBOD/N-RAID array isn't subject to the "same make and capacity" constraints. But how does this setup perform?
Would the speed of the 6G be hobbled, slowed down to the 3G's speed (or worse?), if I were to set up the two SSDs as a JBOD/N-RAID array?
Is this even a recommended idea - that is, paying for the convenience of having one virtual volume by adding the complexity (and risks?) of a JBOD / N-RAID setup?

I am following your advice and attempting to install Bonjour. I wasn't sure where to install it so I am following the VMWare Knowledge Base #1003814: Sharing a printer with a Windows virtual machine using Apple Bonjour.
I have copied it below to refer to because I've run into a problem.
I have completed steps 1 a-d.
The Problem: Step 1 e. Click Printers. Printers is not shown under Removable Devices. When I try to Add Device (Printers) it says "New Devices cannot be added until the Virtual Machine is Shut Down and then Resumed." I have shut down the Virtual Machine alone, I've shut down AMware Fusion and I've shut down both Windows and Mac. Nothing has changed when I try and add Printers so I can do Step e.
I sure hope someone can help.
To configure a printer connected to your Mac for use with the Bonjour utility and a virtual machine in Fusion:
Configure your virtual machine for Bridged Networking and disable ThinPrint:
Click Virtual Machine > Settings.
Click Network (Adapter).
Enable Bridged Mode. In Fusion 5.x, select Autodetect under Bridge networking.
Click Show All.
Click Printers.
Set printer sharing to Off.
Click Close.
Reboot the virtual machine.
Install Bonjour for Windows. Download and install Bonjour for Windows in the virtual machine. Bonjour is available from Apple at http://support.apple.com/kb/DL999.
Note: The preceding link was correct as of January 20, 2010. If you find the link is broken, provide feedback and a VMware employee will update the link.
Share the printer in Mac OS:
Open System Preferences.
Click Print and Fax.
Select the printer you want to share, and select Share this printer.
To configure the printer in the guest operating system with the Bonjour Utility:
Double-click the Bonjour Printer Wizard.
Click Next.
Under Shared printers select the printer you want to use.
Click Next.
Click Finish.

Mac Pro 4,1 SATA for OS and RAID SAS for data?

Hello, Can I setup a new Mac Pro with two SATA drives for the OS and install a RAID Card and two SAS drives for data?
Or do they all have to be SAS or SATA drives in the machine? Meaning I cannot mix SATA and SAS.
Thanks,
Dean

Even MacWorld magazine liked the OWC drives.
If you are serious about using an SSD drive, they are generally too small for, and do not give enough speed improvement to, extensive documents, movies, pictures, Tunes, and so on. You should consider moving the /Users directory to a traditional Hard Drive.
Blocks on SDD drives can sustain a finite number of writes, thought to be in the neighborhood of 10,000. Some Cloning software is thought to do an abusive number of writes during cloning, so it may be better to install the System from scratch onto your new SSD.
I am an advocate of occasionally consolidating free space on an SSD drive and Zeroing it. Since these drives tend to be organized internally as really big blocks, eliminating small "free" blocks (with leftover data in them) may allow some drives to do fewer slow Read-Modify-Write cycles. This practice is, at best, controversial.

Possible to mix SAS and SATA in S10?

The S10 I purchased has the 146GB SAS drive attached to the LSI controller. I see in the hardware reference manual that there are spare SATA ports on the main board. Can I mix SAS and SATA drives on this machine if I am *not* using them in a RAID array? Does the fact that the SAS and SATA are likely to have different rotational speeds mean that I need to be worried about vibration/stability issues?
Solved!
Go to Solution.

SAS and SATA can definitely coexist. rotational speeds won't matter as the drives are harmonically dampened in their trays. in fact, i have three 15,000 RPM SAS drives sandwiching two 7200 RPM SAS drives in my D10 and can't feel any vibration in any of them. i've also hot-plugged SATA hard drives onto the intel controller with no issues.

Mixing ECC and NECC (Non-ECC) RAM Modules

Hi,
I have a G5 Dual Core 2.0 with a pair of 512Mb Non-ECC (NECC) RAM installed and I want to upgrade to 3Gb. I'm thinking of getting 2Gb ECC modules and discarding the 1Mb NECC installed. But I came across a phrase in the Apple Manual of my G5 that states "DO NOT MIX ECC and NON-ECC Memory Modules WITHIN A PAIR." Does that mean I can mix ECC and NECC within Memory Banks and NOT within a PAIR? Because in that case I won't have to discard my NECC 1Gb and have a mixed 3Gb Memory!? I'm afraid to actually try it so I would appreciate your insights. Thanks much.
G5 Dual Core 2.0 Mac OS X (10.4.7)

Yes. You can mix ECC and nonECC as long as you don't pair the ECC with the nonECC. The computer will just treat all RAM as nonECC.
You can keep the original memory as long as the two 512MB DIMMs are always paired with each other.

Mixing XDCAM and HDV?? Outputting to SD DVD...

Hi
Earlier this year we shot a documentary on a Sony PDW-F350L HD XDCam (great camera, stunning footage - 35Mbps). Working in FCP has been fine.
We're doing a follow up and budget and logistics dictate that we sadly can't use 350s again (where we're going, carrying 2 Z1s for example is going to be a lot easier). We're also on a fairly steep learning curve (being relatively new to FCP, Compressor etc).
So I'm looking at options. We know that there are significant differences between say a Z1 and a 350 but from my research so far and from some relatively simple testing mixing Z1 footage (native) and 350 footage on FCP, at least editing on the timeline doesn't seem like it's going to present any problems (although thoughts on that welcome).
The issue seems to be outputting. In the first instance we'll be outputting to SD DVD. Yes, that old gem...
Searching round various forums, it seems this problem (HDV - SD) is fairly universal. Solutions seem to range from not working in Native HDV (suggestions vary on the format to ingest in - AIC etc); outputting to different formats first (eg DVCPro HD) and then to MPEG-2; outputting the timeline to tape (DV), re-importing; using some thing like a Matrox MXO to output and others...
We're aware of the shortcoming of HDV and the compressed nature of the format and our expectations, given our kit are realistic. I've even tried putting some PD150 footage on the timeline but that's just not going to cut it.
So, I've got to put a kit list together by next week and wondered if anyone had any thoughts on:
1) Mixing XDCAM and HDV on the timeline and any gotchas we should watch out for.
but more importantly
2) Any suggested routes I can look at to get some reasonable output with these two formats on the timeline - particularly HDV (don't think we'll have time to look at the Matrox route right now).
Many thanks in advance for any thoughts.
Cheers

Thanks Andy, Michael
That's good input. From an editing point of view we seem to be ok. Although, Michael, I take your point and that's a good suggestion.
The main problem is the workflow to create a decent SD DVD without the artefacts caused by compression/motion etc in HDV (and to some extent XDCAM).
Have read the prores whitepaper at
http://images.apple.com/finalcutstudio/resources/whitepapers/L342568A_ProResWP.pdf
And looked a little more into understanding GOP structures and it seems that ProRes will help in terms of editing.
The white paper seems to suggest that converting to ProRes, because it uses I frame–only encoding "Ensures consistent quality in every frame and no artifacts from complex motion. "
We'll try some tests but, does anyone know if this is true?
But it also seems that deinterlacing may solve some of the horrendous vertical edge rippling we're getting on the HDV footage when outputting to SD DVD - although if I'm honest I'm not sure how we achive that with our current setting.

Mixing static and dynamic content in a single outputText value causes NPEs

If it matters, I'm using the reference implementation version 1.1 (as included with NetBeans 5.5RC2) on SuSE 10.0 w/ JDK 1.5_09.
Thanks,
Bill

Yes, that's how I originally had it, but then changed it to the outputText approach since a single tag could do what I wanted, as long as I was allowed to mix static and dynamic content within a single value.
I think this is a bug in JSF 1.1, since if what I am doing is illegal, it should throw an exception on the first page view, not work on first view and throw an exception on subsequent views. I'm guessing that this has something to do with the fact that on first page view it only runs the restore view and render response JSF phases, while on subsequent requests all of the phases will be run, and it's in one of those other phases that the exception is thrown.
For now, multiple tags is the work-around, I guess.
Thanks,
Bill

Adding a jar to the classpath of an executable jar (mixing -jar and -cp)

Hello,
frankly I hesitated over posting this to "New to Java"; my apologies (but also, eternal gratefulness) if there is an ultra-simple answer I have overlooked...
I integrate a black-box app (I'm not supposed to have the source) that comes packaged as an executable jar (with a Manifest.MF that specifies the main class and a bunch of dependent jars), along with a few dependent jars and a startup script. Long story short, the application code supports adding jars in the classpath, but I can't find a painless way to add a jar in its "classpath".
The app's "vendor" (another department of my customer company) has a slow turnaround on support requests, so while waiting for their suggestion as to how exactly to integrate custom jars, I'm trying to find a solution at the pure Java level.
The startup script features a "just run the jar" launch line:
java -jar startup.jarI tried tweaking this line to add a custom jar in the classpath
java -cp mycustomclasses.jar -jar startup.jarBut that didn't seem to work ( NoClassDefFound at the point where the extension class is supposed to be loaded).
I tried various combination of order, -cp/-classpath, using the CLASSPATH environment variable,... and eventually gave up and devised a manual launch line, which obviously worked:
java -cp startup.jar;dependency1.jar;dependency2.jar;mycustomclasses.jar fully.qualified.name.of.StartupClassI resent this approach though, which not only makes me have to know the main class of the app, but also forces me to specify all the dependencies explicitly (the whole content of the Manifest's class-path entry).
I'm surprised there isn't another approach: really, can't I mix -jar and -cp options?
- [url http://download.oracle.com/javase/6/docs/technotes/tools/windows/classpath.html]This document (apparently a bible on the CLASSPATH), pointed out by a repited forum member recently, does not document the -jar option.
- the [url http://download.oracle.com/javase/tutorial/deployment/jar/run.html]Java tutorial describes how to use the -jar option, but does not mention how it could play along with -cp
Thanks in advance, and best regards,
J.
Edited by: jduprez on Dec 7, 2010 11:35 PM
Ahem, the "Java application launcher" page bundled with the JDK doc (http://download.oracle.com/javase/6/docs/technotes/tools/windows/java.html) specifies that +When you use [the -jar] option, the JAR file is the source of all user classes, and other user class path settings are ignored+
So this behavior is deliberate indeed... my chances diminish to find a way around other than specifying the full classpath and main class...

I would have thought that the main-class attribute of the JAR you name in the -jar option is the one that is executed.Then I still have the burden of copying that from the initial startup.jar's manifest. Slightly less annoying than copying the whole Class-path entry, but it's an impediment to integrating it as a "black-box".
The 'cascading' behavior is implicit in the specification
I know at least one regular in addition to me that would issue some irony about putting those terms together :o)
Anyway, thank you for confirming the original issue, and merci beaucoup for your handy "wrapper" trick.
I'll revisit the post markers once I've actually tried it.
Best regards,
Jérôme

Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array. The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use. I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets. I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets. I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet.
To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
Anyone care to share thoughts/perspectives? Thanks
Bill

Thanks for the speedy feedback Harm - I appreciate it.
I was thinking RAID level 3 as well.
Of course, it's always something! I purchased the Caviar Blacks by mistake - which are non-TLER. I will work with EggHead to return the ones I purchased and replace them with RE4 versions as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives - I suspect WD is way beyond that now anyway with current builds.
I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller. When I benchmark them I'll post the results in case others are curious.
Thanks again....off to EggHead!

Windows 8 and Raid 5 (English)

Looking for confirmation that Windows 8 does not have the ability to use Raid 5 even if it is presented a single logical drive by a controller.
I have a SABERTOOTH 990FX R2.0 that makes a drive. All the docs say Raid 0 and Raid 1.
The Windows 8 and Raid 5 question already posted looks to be in Spanish.
With regards,
Quentin L. McCallum, CISSP

Software RAID 5 is not supported on Windows 8. You can use Storage Pool.

How to install the driver of the 'SCSI and RAID Host Controller'

Hi,
I have two Windows XP(32Bit) installations:
•Windows XP SP2(32Bit) which is old and it seems as if it is infected by some viruses.
•I have installed another fresh clean Windows XP(32Bit) SP3. However, I have found that there is no category named with ''SCSI and RAID Host Controller'. However, when checking out the old version of Windows XP, I found 'SCSI and RAID Host Controller'
is there. (Screen shot below)
The new Windows XP(32Bit) SP3, there is no 'SCSI and RAID Host Controller'
My motherboard is:
My Desktop Computer(Intel P 4, 512MB of RAM, and Graphics Card with 256MB of RAM.
]I am seeing that most computer doesn't has the scsi / raid controller . in the old Windows XP on my computer that SCSI and RAID controller exists, and it it has not a yellow mark on it.
When I installed a new windwos XP 32Bit SP3, no SCSI/RAID in divice manager .
My computer sound on new Windows XP doesn't work , however, on old Windows XP SP2 works well. I have a buitl-in sound card. SCSI and RAID controller category in the device manager on the old Windows xp SP2 is realted to sound card,I don't think.
Thus, What drivers would let the 'SCSI and RAID Host Controller' added in the device manager?
A man should convert his anger and sadness into strength to continue living in this life.

If you open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on the pcb somewhere. You should also normally see this information on the first POST screen when you turn on the PC.
Otherwise Google "775i65G" like I did.
Here are the driver downloads (assuming it is an Asrock 775i65G R2.0 and not an R3.0)
http://www.asrock.com/mb/Intel/775i65G%20R2.0/?cat=Download&os=XP
You should install the inf driver first. Hopefully after you do that you will see your desired listing in Device Manager.
With regard to the AMR driver and the HDMR driver, you can find some information about these here :
http://en.wikipedia.org/wiki/Audio/modem_riser
Unless you actually have something plugged into these risers, it is probably not necessary to install the drivers.
However, the drivers for the integrated C-Media audio chip and the Realtek Lan chip may prove useful.
It looks like the motherboard has integrated video but if you are using a graphics card it will not normally be necessary to install the VGA driver.
You can download both the manual and the installation guide here
http://www.asrock.com/mb/Intel/775i65G/?cat=Manual
And if "SCSI and RAID Host Controller" is still not shown in Device Manager, don't worry - because these functions are not supported by your motherboard (again assuming it is an Asrock 775i65G)
Thanks a lot,
First of all, when saying that I have multi-operationgs systems, I mean there are two operating systems installed on my PC(SP2, SP3) both are 32Bit. The first Windows SP2(NOT installed by me) has all multimedia audio card installed
well, and has SCSI and RAID Host Controller shown the device manager. However, only the VGA is not installed on Windows SP2. However, the second one Windows SP3(Installed by me) has VGA not installed, Multimedia audio NOT installed, and there is no SCSI and
RAID Host Controller in device manager.
First: Why did the CPUz, specy didn't detect motherboard name, and only detect the model. IF I need to open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on
the pcb somewhere, then what benfit would be there from hardware detection software?
Second: Yes, my motherboard has integrated video, and integrated audio card
However, this doesn't mean that I don't need to install them since the Vidoe controller is not properly installed (it is a default VGA ) Also, Multimedia audio controller is not functiong at all.
Finally: if And if "SCSI and RAID Host Controller" is still not shown in Device Manager in Windows XP SP3, because these functions are not supported by my motherboard, then why is 'SCSI and RAID Host
Controller' installed/shown in the device manger in Windows XP SP2 on the same PC???

Since installing IOS 5 on my iphone4, the music gets mixed up and sometimes it won't even play it !

Since installing IOS 5 on my iphone4, the music gets mixed up and sometimes it won't even play it !
Even after many tries of sync, it won't work like before...
Anyone had the same problem?

Same problem here, but I found a solution that worked for me:
Altered from original solution from Emily P:
Okay, mine now works here is what I did.
plug in the iPhone, iPad etc
in iTunes select the phone or iPad
Under Summary uncheck "Sync with this....."
Under "Music" uncheck the "Sync Music"
Sync
Let it remove all the songs, dont worry it will come back no problems.
Once that is all done all the music on the phone or ipad should be gone.
Now check them both back on, sync, and everything should copy back onto it.
Working now !!!!!

How do I mix text and Html format in a java mail?

How do I mix text and Html format in a java mail? some part I want to keep the text format, the other part I want to use Html functions(like fond, color, etc)

You don't mix them. Pick one or the other.
However if you want to have a text version and an HTML version, so that mail readers that don't handle HTML can see regular text instead, then you could produce a "multipart/alternative" message. There's an explanation of how to do that in this article:

Word 2007 mail merge : problem with mixed portrait and landscape orientations

Hi there,
I have a 3 pages document Word 2007 file
This is a mail merge I want to export in PDF using Adobe Acrobat Printer,
then send "big" PDF to printing.
page 1 is PORTRAIT
page 2 is PORTRAIT
page 3 is LANDSCAPE
In PDF pages 1 and 2 are perfectly fine, inside an A4 format (width=210 height=297mm or something)
but for page 3, system changed to a "double" sized page (A3 width=297 height=420) and printed my stuff at the 1st top middle of big page.
So I have a big "double" sheet, oriented PORTRAIT, with my stuff in 1st half, and a blank in 2nd half.
It seems that system did not rotate the page... and just put the stuff into a bigger sheet to "solve" at best.
I would like the same size of paper (A4) but in landscape : width=297 height=210
I have already seen many PDF with mixed portrait and landscape orientations, so what's the thing ?
With my advanced thanks,
And greetings from Paris, France !
Vince

Some questions:
Which version of office were you using before? 2003?
Are the data files on a network, or on your local machine? If they are on a network, can you make a copy of one of them on your local machine and try again?
Can you open the files directly in Excel? What extension do they have (.xls, or something else?) I am wondering whether access to other file types has been left blocked on your machine but is allowed on your colleague's machine.
Are you just opening the mail merge main document and seeing this message? If so, do you see the same thing if you start with a new document and try to connect to one of these data sources?
Can you confirm that the message is about Access even though you are trying to connect to an Excel file?
(Also, office 2007 has some new stuff - that let's you specify that certain folders are "trusted" . I don't think that ever affected MailMerge but it may be as well to make sure that your documents and data sources are in trusted locations).
Also worth trying to start Word in "Safe mode" - see, e.g. http://office.microsoft.com/en-gb/word-help/work-with-office-safe-modes-HP010140792.aspx
