Xserve Raid - use it as standalone storage?
hi there!
i have a small network with some pcs (3 running winxp, 1 win2000), 2 os9 macs and 2 g5s. i need big data storage in the size of 7-10TB. can i use the Xserve Raid as standalone storage in the network, or does it need the xserve as server?
do i need soomething else apart from the Xserve Raid to setup the storage bank?
is it a good idea to connect the pcs via ethernet and the g5s via fibrelink? (because our files we are working on are very big and need to have fast access on the storage drives)
thx for ur help

The XServe RAID needs a host system. That host system doesn't need to be an XServe, or even a Mac - people are using them quite happily on Solaris servers, Linux servers and even Windows servers.
However, it does need a system that had Fiber channel.
ALL disk activity happens over the fiber channel connection. The ethernet ports are not used for file activity, only for administering and monitoring the box.
If you hook the XServe RAID to a single host via fiber channel, that host can share the volume over the network to other clients so they get indirect access. Alternatively you can use a fiber channel switch to connect multiple systems, but care needs to be taken with regards to multiple clients reading/writing the same file at the same time (which is typically why you need SAN software to manage this kind of setup).

Xserve RAID using DHCP - DNS field = 127.0.0.1
I have four Xserves all getting a static IP address from a 10.4.11 OS X Server.
They get the IP address, subnet mask as well as gateway address correctly from the DHCP server BUT the DNS server address is NOT populated - it displays 127.0.0.1
All the other clients on the LAN DO get the DNS server address.
NB All RAIDs are updated to latest firmware (1.5.1 IIRC)Hi,
Ping localhost is a loopback process to verify the TCP/IP is configured correctly on the local computer. So, the TCP/IP configuration or stack contains a corruption, first, I would suggest you check you check you TCP/IP settings, reset the
TCP/IP stack by using NetShell
http://support.microsoft.com/kb/299357
Since the Ping is timeout via ipv4 but Ok via Ipv6, so it's also recommended to just reset the ipv4 setting via the following command and check the result
netsh interface ipv4 reset

Expanding xServe RAID Array - updated info sought.
I don't want to have to reformat the RAID and I don't want to lose data because...
1) The organization will suffer extended downtime.
2) I don't have ready access to 3TB of empty storage to back up the entire contents of the RAID.
These and Apple's documentation are a few of the many different sources of info on this topic I've sought.
With apologies in advance to William Lloyd, who has answered many of these questions.

My (familiar) situation.
I inherited administration responsibilities for an xServe RAID using the latest firmware (1.5.1).
The xServe is an intel xeon dual 2 GHz, running Mac OS X Server 10.6.8
The RAID had six (sigh) drives in the left controller. None in the right.
When I became admin, one of these six was dead. So I went on eBay and got three refurb ADM's.
--one to replace the dead drive.
--another to expand the RAID 5 to a full seven drives. (from 2.5T to 2.73T)
--a third to put on the shelf as a spare.
Now then.
The replacement drive rebuilt beautifully. Happy 6 drive RAID.
I put in the 7th drive and expanded. It took several days.
I'm at the point of "merging" slices that gives everyone pause about losing data.
Much discussion here about whether this can result in added capacity without destroying data relates to earlier versions of Mac OS X Server and G5 not Intel xServes. So that's a point that I think I could use some clarity on. Can Intel Macs can expand the file system with this slice-merging function without data loss whereas Power PC Macs cannot?
Next, my RAID as I inherited it was one slice. That is to say, one volume. One partition. In RAID Admin under "Arrays and Drives" all the little drives display a [1]. They did when the RAID was degraded to 5 drives. They did when I added the 6th drive replacement. They do now, having used the Expansion function under "Advanced" to add the 7th drive.
So, next question. WAS IT EVER SLICED?
That seems to be a deal-breaker for merging slices without data loss.
For this, I looked in RAID Admin to my Events tab which dates all the way back to 2008.
I see exactly zero mentions of slicing anywhere. Come with me on a journey, won't you?
You'll see my expansion and verification up top.
The drive failure in October 2013.
Other exciting things. But no slicing.

Xserve RAID installing Firewire 800
Hi,
would like to know if it is possible to replace nor insert a firewire800 card on an Xserve RAID?
at the moment we can't afford yet to use Fiber Channel, so we are wondering if we can use the RAID in firewire connection?
Let me know...
Best RegardsUsing XServe RAID? No.
The XServe RAID uses a Fiber Channel interface to the host system. FireWire is not an option.
Im not sure I understand your question, though. The cost of the Fiber Channel card for the host system is $500, not much when you consider the cost of the XServe RAID itself. If you already have an XServe RAID then there's not really much additional cost.
On the other hand, if you don't have an XServe RAID and you're looking for a RAID solution (not necessarily an XServe RAID), then you can build a RAID system out of any attached drives, whether they're FireWire, S/ATA, SCSI, or any other supported interface. -
Dumb?? How do I tell if an XServe Raid is a G4 or a G5??
I've looked all over the RAID Admin.... Is there any way to do a "Get Info"??
It's NOT listed in the "Info" screen.
Thanks>So any Apple Drive Module will work??
With the latest XServe RAID firmware and ATA drive modules, yes.
The 'original' XServe RAID came with 180GB drives. Then they added support for 250GB drives, then 400GB and now 500GB.
With each new drive size there's been a corresponding firmware update. The updates add support for the new drive size plus new features.
So if your XServe RAID is running the latest firmware you can use any of those drive sizes. The only other consideration is SATA vs. ATA. The XServe RAID uses ATA Drive Modules, unlike the SATA Drive Modules employed by the XServe G5 - you can't take a drive module from a G5 and put it in an XServe RAID. -
How to low-format disks in XServer RAID
I am new to the macworld and have been assigned a mission to low-format 2 XServer RAID with 28x400Gb Hitachi Deskstar disks. I need to low-format it because the customer is about to sell the servers, and are therefore obliged by law/or insurancecompany to make sure that no data can be restored.
I have tried to extract the disks and run them in a PC with a software called KillDisks, which writes zeros to the disk 10-fold times. However the PC will not accept the disk, im getting errors that states that no sectors can be read. Also, in BIOS the disk are supposedly 126 Gb...when in fact its capacity is 400 Gb.
Sounds like the Apple firmware is not compatible.
So, my question is...can I perform this task from inside the XServer, via some webinterface or perhaps the remote adminapplication?I see you point but I mostly meant the need to extract/take apart the drives.
The job was to make the data (reasonably) "unrecoverable"?
(The KillDrive application can maybe even "destroy" drives for Xserve RAID use?)
Maybe not relevant here but the Xserve RAID woun't "buy"/just work with "any" drive/firmware.
He shouldn't even have to "reformat" raid-sets as you can write zeroes to each whole raid-set volume from the Disk Utility using the "security option" (will take a lot of time though - but probably much less time than doing it for each drive individually - if JBOD or otherwise).
Maybe even possibly started from OS X install DVD (if servers are "wiped"). Don't know if FC drivers are present on the DVD, but think they are.
(Also a "Mirror Door" G4 or Xserve G4 can probably "format" (really initialize) these drives and can at least hold up to 4 drives at a time.)
And you can manage (but not erase drives/volumes on) the Xserve RAID from any computer (if you know the IP) using the Java RAID_Admin.jar file that is "extractable" from The OS X version file (.app) "package". And it can be run on (most?) OSes that can run Java. Certainly from Windows with Java installed.
And you don't buy a couple of old preowned used Xserve RAIDs and spend a huge amount to restore data if you don't think/know it's REALLY worth the while. -
Xserve Raid not recognized by Disk Utility
My Xserve Raid is recognized when I run the RaidAdmin utility. I can create new arrays everything shows up without any problems. I updated the firmware for the Xserve Raid using just the ethernet connection to administer it. Changed the card and the cables that are used to connect the Raid server to a G5 server, but it still does not get recognized by Disk Utility. I am at a loss of what to do next. I have green lights for everything....no problems showing up in RaidAdmin. Please, please help....
Hello
I have the exact same problem: after updating java and rebooting the server, the raid array is no longer visible. Everything is green, no errors in the log files, fibre channel is up and running, BUT: the array does not show with any SCSI address. LUN masking is off. Server is at 10.5.8 (intel). The array was mounting just fine before the reboot (and all before that). I've plugged the fibre channel into a PPC server, same thing: link ok, no SCSI. I'm reconditioning the drive at the moment, but it should still be visible.
Any help greatly appreciated. -
Is it possible to use Serial ATA disc's (SATA) 500GB on a Xserve RAID with 4 Ultra ATA disc's of 500 GB?
No. The XServe RAID uses ATA disk and are not interchangable with other bus technologies.

Clarification on how to use Xserve Raid and Fibre Channel without xsan.
First let me apologize for not responding earlier to your response, I tend to get busy and then forget to check back here.
Tod, the answer to your question is No, only one computer is accessing the xserve raid files at any one time and that is via Fibre Channel. However I do have the xserve raids set up as share points via ethernet.
Maybe I should turn that off and only access the files with the one computer that can connect via fibre channel.
I never thought of that. I will try that while I await for your answer, thanks again.

I have the following setup:
Xserve: 2x2Ghz Dual Core Intel Xeon, 5Gb of Ram, Running 10.5.8 Leopard Server
Xserve Raid with firmware version 1.5.1/1.51c on both controllers, and
Qlogic Sanbox 5600
Apple Fibre Channel Cards in Xserve, and Mac Pro Tower; Apple 2 Port 4Gbs Fibre Channel Card
Mac Pro Tower-Quad Core Intel Xeon 2.8Ghz, 16Gb of Ram, Running Snow Leopard 10.6.4
Here is the problem.
The directory for the xserve raids keep getting corrup, and I use disc warrior to rebuild them. Is there a way to keep the directories from getting corrupt? I am a few pieces of equipment before I can build an Xsan as that is the ultimate goal, but until then, I just need to be able to have the raids funciton as storage without having to rebuild the directories all of the time.
Anybody have any suggestions?
Thanks

Are multiple computers accessing the same data on the RAID at the same time?
If so then NO. This is the source of your data corruption and I'm surprised if you were able to get all your data back every time if this is how you've been running your system. Each fibre channel assumes it has full and sole control of every volume it has mounted, no data arbitration is practiced and data corruption will occur if this assumption is wrong.
The only way this set-up will work is to use partitions or LUN masks so the volumes are accessed by one computer at any time. As long as one computer relinquishes control before another mounts it you will dodge arbitration issues but this is a dangerous game. If you screw up and mount an already mounted volume - and there is no easy way to tell if a volume is mounted - corruption will then occur. Sharing data simultaneous at fibre speeds is what XSAN does and to do this you need it.
HTH,

Intel Xserve, G5 XServes, XRAID, Promise+The xserve raids will mount automatically to any computer that I connect the qlogic fc switch to+
This is source of the corruption to your data. Any computer that attaches to a drive/partition via fibre channel assumes that it alone is in control of the drive and data corruption is inevitable.
+Is that the issue, should I disconnect the xserve from the fc switch and leave it connected via ethernet?+
Short answer: YES. The ethernet connections are fine because the server is controlling the file arbitration through the sharing protocol. Fibre channel connections assumes complete control over the partition and no arbitration of the file access is performed. It's like two people independently driving trying to drive the same car to different locations.
Depending on your set-up it is possible for the two machines to see and use different parts of the Xserve RAID storage but they cannot access the same areas without SAN doing the arbitration.
Hope that's clear,

We have a serious need for a NAS system in our studio. And coincidentally, we have a 3 yr old XSERVE 5.6 TB RAID - just sitting around, unused.
The Xserve has the standard Fibre Channel ports for mounting it onto a your computer (as well as the Ethernet ports for admin).
My question is, has anyone used their XSERVE as NAS? I know I could hook-up a CPU to my xserve and make it work that way, but I don't have an extra G5 laying around.
Thanks,
TomUse some caution on the terminology here, as there are Xserve and Xserve RAID widgets, and these are quite different.
There needs to be a computer or controller here to act as a router between clients expecting to have Network Attached Storage (NAS) and a Fibre Channel Storage Area Network (FC SAN) widget such as the Xserve RAID.
There are controllers which allow SAN storage to be served via network, but these typically operate by providing a complete separate path (NAS) into the storage. Via iSCSI or AFP or SMB into the controller, for instance. (And I'd expect there isn't much in this product space for an Xserve RAID array; I am aware of a few vendors that do offer storage arrays that can be acquired with one or both of iSCSI and SAN bus interfaces, but Apple doesn't AFAIK offer this with Xserve RAID.)
I'd probably look to sell the Xserve RAID and (if you have it) the FC SAN Host Bus Adapter (HBA) you were using, and use any profits to offset the cost of acquiring a replacement NAS storage array widget, or to acquire a Direct Attached Storage (DAS) storage array that can be served off one of your existing host(s). A SCSI or SAS shelf hanging off FireWire 800 or a SAS controller can do quite well in this regard.
I'd tend to guess you'll spend more - if you don't already have a Mac Pro or Xserve and FC SAN giblets you can connect to the Xserve RAID - than wholesale replacement with a DAS or NAS widget. 5.6 TB is approximately three current-generation disks, or four of the previous 1.6 GB generation disks. A four- or eight-bay Drobo is in this range, as are many other solutions. Or "just a SCSI or SAS storage shelf" configured as DAS can work fine, too. (And disk storage shelves are available from various vendors.) -
Which 750GB drives used in an XServe RAID?
Could somebody with an XServe RAID with 750GB drives please tell me, which drives are used in this configuration? You can look it up in the XServe RAID admin utility, under Arrays and Drives when selecting a drive in "drive" mode.
Thanks a lot,

HUGE Troubles with xServe RAID formatted 10.4 and using it with SLS 10.6
Hi All,
We met today a huge trouble using an Apple xServe RAID (formatted HFS+ with a Mac OS 10.4 Server PowerPC G5).
This RAID has been plugged with a new xServe Intel Xeon (Model xServe 3.1), MacOS X 10.6.2, Apple FiberChannel card 4 GB, the link is at 2 GB.
There is also an Infortrend RAID FiberChannel 4 GB Fiber to SATA RAID attached to this new Intel Xeon server : this RAID drive mounts correctly, no troubles.
BUT the "old" xServe RAID is not able to mount at all while plugged with this new Intel Xeon, DiskUtility claims the volume needs repair !!! We try a repair = failed !!!
The xServe RAID has been formated under 10.4.6, HFS+ Journaled.
The Infortrend has been formated under 10.6.2, HFS+
Does anyone met a such case ??? We tried using SFP to SFP Copper cable or Optical Fiber + SFP/LC Transceiver = same results
Many thanks a lot for your opinion !!!
Regards.What if you connect your "old" xServe RAID to a non SLS server if you have one available? Preferably one running 10.4.x server to match your HFS format. If the data on the old RAID is so critical that you can't afford to lose it, you could always pickup a used PPC w/ a fibre channel card and install 10.4 server on it just so you can transfer the data. Curious to see what you end up doing.

I have an Apple Xserve raid that I connected to a Dell PowerEdge 1950 using a QLogic Sanblade QLE2460 card. I currently have 7x750GB drives installed in the raid that yields around 4TB of usable capacity. I am running Red Hat 4 AS and created an ext3 file system. I have unfortunately had two occasions where the file system has gotten corrupted somehow. The file system seems fine until I shutdown cleanly and reboot. After booting, the partition table appears corrupt showing the file system is 4GB put the drive is much smaller. Is there a better file system type that is known to work with the xserve raid? Could this be a driver or kernel issue? Thanks!
Hello RandyMartin and welcome to the Apple boards,
I don't know how many people here are running your set-up, but hopefully someone will chime in with some ideas.

Good luck,

3TB Storage - Alternative to Xserve RAID
Do anybody have any suggestions for alternative storage other than the Xserve RAID?
I'm looking to install an affordable 3TB RAID5 into a clients site, and they don't need a full Xserve RAID as of yet. Pricing and reliability is key also.
Any advice is appreaciated.
Thanks,

Switching to Xserver/Xserve RAID
Hi boys and girls...
I was looking for a little assistance in switching over to Xserve. Let me give you some background info first.
Were a small studio in London, with only 11 people in-house and the majority working externally whether free-lance, from home or from another country etc. Were mostly Mac based, though 4 machines are those little beige pc things all running XP 2002. At the minute its 1 G5 and a collection of G4 tower's and G4 power book's, G4 cube's and so on. Were all connected to a G4 server running Mac OS X Server 10.2.8 with a very small dual 120GB HD raid thing running Retrospect.
Our problem is, this system was set up some time ago and were starting to outgrow it.
What were looking for is a way to backup all of our current work and archive all of our old work. Most users like to work directly off the server as theres so much file sharing between the macs and pc's, directly updating files so there isnt any duplication etc.
First question, is it possible (and a good/bad idea ?) to have 10-15 users working directly from a Mac server, that stores the archived work for users to reference and also current work which is backed up to tape and duplicated (as we currently have) to another HD?
Secondly, Is the ideal way to be running things? Is there a more efficent way?
Finally, what kind of spec should we be looking at? There's such a huge difference between servers, while were willing to invest, we dont want to go crazy (maybe a little) on costs.
I look forward to your responses and thank you in advance
MarcusThere are certainly some drawbacks with your current setup that mean you should make some changes.
In general, there's nothing wrong with working with files directly off the server, however, 10.2.8 has some issues with multiple users accessing the same files at the same time, so you should look to move to 10.4 ASAP to address that issue, regardless of any other changes you make.
I am assuming that the remote users don't work this way - uploading/download files as appropriate - it would be painful to work off the server remotely.
The only real disadvantage with working with files directly off the server is that if a file is changed erroneously and saved, there's no easy backup.
If the file was copied to the local drive and saved, it's easy to roll back to the previous version by re-copying it from the server, but if that change is saved directly to the server the only rollback involves pulling out Retrospect.
The other change that would make a difference is installing a gigabit switch and connecting the server to it. Even if all the host systems don't have gigabit ethernet, the extra bandwidth to the server will definitely help.
As for a new server, 10-15 file sharing users are not likely to stress the server, do you don't need a top-of-the-line configuration.
You should first decide how much disk space you need. With 500GB drives, the XServe can handle up to 1.5TB on its own, without any additional XServe RAID. However, you might want to consider RAID (using RAID you're limited to 1TB of RAID 5 storage, or 500GB of mirrored storage in the box).
In addition to your current data usage, consider using an online disk backup where multiple copies of the data is stored on the server itself before (or in addition to) backing up to tape.
While tapes offer several long-term archive advantages, they really don't work so well for quick restores of a file or two. Having a snapshot of the last couple of days data online makes it trivial to step back a day or so without having to resort to tapes. This may mean, though, that your 100GB of data requires 200 or 300GB of disk space.
If you do decide than an XServe RAID is the right solution, consider getting it right-sized from the get-go rather than buying it small (e.g. 4 drives) and adding later. While it can be done, adding drives to an existing array is a PITA.
If you do opt for an XServe RAID, and you don't currently have any rack-mounted equipment, consider using a PowerMac G5 as your server rather than an XServe. While similar in terms of performance, the PowerMac can work out cheaper depending on configuration.
