4Gb Xserve Raid Card to 2Gb Xraid Fiber Channel

Greetings All,
Does anyone know if a 2x4Gb Fiber channel card will auto-negotiate down to the 2Gb level of my Xraid?
Thanks,
-dave

Yes it does. I've done it and the newest Xserve is plug and play with the old Xserve RAID.

Xserve raid card failing? 3 x 1Tb drives

Hi all
I've had an xserve running for the last month or two now, it has been subject to frequent crashes...
I have applied the latest 10.5.5 update and haven't had a crash for some time now.
This morning I happened to have a look at the server monitor, and there was an error...
I'm a little confused... especially when the xserve is also connected to an APC UPS unit.
Should I be worried about this... is something lurking around the corner?
*Any help/suggestions appreciated.*

This is covered in the RAID Utility User's Guide on page 12.
Every 3 months the RAID card will discharge and recharge the battery. During this process, you will see the message.

Xserve RAID Card: Is setup kept when reinstalling OS?

Hi everyone,
I have a new Xserve with 3x 1 TB and the RAID Card. The default setup is JBOD and of course I'd like to change that by booting from the DVD and setting it up. I know that I can convert JBOD to RAID while keeping the already installed OS. But since I plan to reinstall the OS anyway I was wondering if my chosen RAID setup will be preserved this way?
I believe this is a real Hardware-RAID so this should work, right?
Thanks
Björn

Thanks,
since the RAID can't be reconfigured while booted off one of the internal drives and since this can't be accomplished remotely using Server Assistant I need to reconfigure it with another (external) system. Is that true?
I suppose it could also be done directly at the Xserve, but I do not have a Mini Display Port Adapter at hand, so this is currently no option. It seems to work with an external FW drive running OS X 10.5.7 (Client) which has the RAID Utility on it...

Why do Xserve RAID cards take so long to ship?

I have ordered three RAID cards (I need two and I was advised to get an extra for a backup) for our early 2006 Xserve. The cards are due to ship in just less than a month, why so long?

It's probably an issue of supply vs. demand - in this case, the demand for such cards isn't high, so there aren't many in the supply chain.
Typically even the manufacturer doesn't keep a local stock of low-demand items, instead running periodic production runs when there's sufficient demand. So some of the delay may be in waiting for the orders to queue up to a level that warrants a production run.
Even if there is a stock, some manufacturers have minimum order values (e.g. they won't fulfill and order for less than $x, or y units), or offer significant discounts for large orders (thereby making one-off orders cost prohibitive), so the delay may be in Apple queuing up the orders until there's sufficient quantity to make it worthwhile.
Either way there isn't much you can do unless you can find another reseller who has one in stock, or go used.

Xserve Raid Card battery conditioning

Good afternoon, I have observed that the raid controller on my Xserve run conditioning cycle the batery every 3 months... is that normal?
I appreciate a clarification on this.
Thanks.
Hipolito Lopes

Hi Hipolito,
3 months is normal. It's a shame you can't choose the time of day it does this but it's generally around the 6hour mark for the conditioning to take place.
Hope that helps

Xserve RAID card reconditioning battery

Hello,
Does anyone know if there is a LaunchDaemon or script where i can schedule my battery reconditioning ?
It is always starting in the middle of a working day and the performance is then very slow.
Or did anyone tried to disconnect the battery cable an put write cache on ?
Tnx,
Harry

Seems to me to be a hardware design fault…
It has a mind of it's own –literarily– it's own internal control logic determines when this happens
– I have not seen any way to 'control it'
– Personally I consider this to be a major design fault…
– Would be OK if could control it
– OR if it had two batteries and could swap between them
– Neither of which seems to be the case…
I could be wrong – but I've never found a way to control it
– Seems to have a habit of choosing the most in-opportune times to recondition it's battery
– if it works at all…

XServe and XServe Raid Configuration

Hello Community,
I have taken over IT for a photography company. We deal with huge amount of data (3 GB files) on a daily basis. We are running a FMP database too.
We are trying to upgrade some of the computers to Snow Leopard since we are running old software (hopefully Lion by the end of the year). We have to upgrade in stages since we are still running G5 servers with Tiger and FMP 6.
We have:
* G5 Server and 1 Node
* Intel Server (2008) and Intel Server (2009) (NEW)
* 3 Xserve RAID (1-NEW)
Just found out that Xserve RAID only uses Ethernet for admin and that the extra port is redundant. This frees up ports on our switch since we have been plugging them all in on the same network.
Currently
* Server 1 plugs into RAID 1 using fiber cable (both ports) also runs FMP server and our FTP
* Node plugs into RAID 2 using fiber cable (both ports)
NEW
* Intel server 1 plugs into RAID 3 using fiber cable (both ports) (Not turned on yet)
We know XServe RAID only supports 2Gb/s fiber channel. Is that 1Gb/s per cable?
Does anyone know of a better way of configuring this server layout?

To join, or bond your ethernet ports, you need to delete your separate network interfaces in System Preference and create a new link aggregate interface. This article is for 10.6 but the theory is the same in other versions of Mac OS X and Server:
http://docs.info.apple.com/article.html?path=ServerAdmin/10.6/en/asa7873dc0.html
You will need to configure your switch with a LACP port bond as well. As dawendt has mentioned - if your network is based on 10/100 switches then making a 2Gbps link aggregate on your XServe won't help.

XSERV RAID FIBER CHANNEl

We have XSERV RAID MODEL A1009 with 4 Hard disk RAID 5.
Now I have installed CISCO 1000Base SX Module in 3 COM Switch & other same Module in XSERVER RAID. Now XSERVE RAID & switcted with Transeiver cable. Now I check RAID ADMIN TOOL FIber Channel Option the links shows down.
Let me know what is solution. Please also let me know how can I know that fiber link is up if any way.

Finisar makes a nice SFP to LC transceiver (available on the Apple Store for $99.95 for 2 Gbit and $119.95 for 4 Gbit) that you can use in the Xserve to allow it to accept LC optical cables. You'll need 2 of these, and then you can hook up LC optical cables.
I'll echo the other post -- be aware those ports are for fibre channel communication ONLY. You must hook it to a fibre channel card (HBA) in a host, or to a fibre switch (i.e. Cisco MDX 9000 series). You cannot hook up a network connection to those ports -- Xserve RAID provides data ONLY over fibre channel, it is not a NAS device. You must connect it to a host which can re-share the data over Ethernet, for example Xserve RAID with OS X Server which can reshare using AFP, SMB/CIFS, NFS, FTP, DAV, and more.

Connecting xserve to xserve raid - done everything

Hello,
I'm having trouble connecting my secondhand xserve to xserve raid.
- xserve is running 10.8.5
- i'm screen sharing the xserve
- I have reset both the RAID controllers with paperclip
- both fiber channels are connected
- both controller cards are connected to the xserve via ethernet
- half the hdds in both sides of raid show red light
- it has been on for 24 hours now
Add system in RAID Admin doesn't propose anything, so I have manually entered the ip addresses from server.app>network pane.
If anybody has any ideas I would be thankful.
Paul

There are several possibilities.
First off, from your screen shot, both your RAID and your host are using the same IP addresses (169.254.192.90 and 169.254.87.107). That's not going to work. However, it's probably not your major problem... let's move down the stack.
Your interface on the host isn't connected/configured corrected - as noted by the Orange ball alongside the IP address. You need to fix that.
Second, the 169.254 addresses are somewhat variable, so just because the RAID had that address at one point in time that doesn't mean it still has that address - it could have changed. This may or may not be the case, depending on the link status of the host system.
If you choose to Add System within RAID Admin, it will search over the network to find nearby, available RAID systems to add. This is usually better than relying on dynamic IP addresses that might have changed since you last configured the array.
In either caase, focus on the link to your host. Check if you can at least ping the RAID. Use a tool such as tcpdump to see if you can determine the IP address of the RAID (hint: you should see it broadcasting on the network link).

How to install 1 xserve and 2 xserve RAID ??

Hi i'm new at fiber world. Could anyone tell me how can i install 2 xserve raid on 1 xserve? In this moment i have 1 Xserve and 1 Xserve RAID conected directly with 2 fiber cables. I need to buy other xserve RAID but how can i conect it? i have to use a fiber switch? and if this is correct wich switch u recomend?
A link with schematics will be apreciated.
Thx in advance.

In the sense that you can plug everything in and it will auto-negotiate and things will just "show up" then yes it is like an ethernet hub.
You will probably have to do some simple configuration of the Sanbox via their admin tool but as long as you're only using the Xserve/RAID it should be easy because you just have one zone and all full speed ports. The QLogic docs are good, if basic, and the admin tool is pretty straightforward - especially for an easy set-up like this.
The way that fibre is not like ethernet (just so you're aware) is cannot have two Xserves plugged in sharing the same drives. This will work if you try it but horrible data corruption will eventually occur. Fibre is like ATA or SCSI and you can't share it between host computers in it's raw form. Just to be clear.
Good Luck,

4 xserves + xserve raid setup?

Hello,
I have ben using xserves independently (no raid storage) for many years now.
Now, I would like to hook all my xserves (G4, G5, intel) to a xserve RAID and have the xserves all share the storage on the raid.
I know this is a broad question, but what do I need to set this up?
These servers are primarily web servers, so no user files are involved.
TIA for any tips/pointers given
P.S. Should I wait on the new RAID (rumored to have switch and sata drives)?
MaBook Pro 2.4 GHZ | 4GB RAM, 7200 HD Mac OS X (10.4.10)

First you have to look at the volumes. Are you planning/hoping to have all servers directly access the same files? If that's the case you're going to need some kind of SAN solution such as Apple's XSAN ($1000 per node, plus a dedicated controller server)
Then, in order to physically connect multiple servers to a RAID you will need a fiber channel switch. This will let the four servers connect to the two ports on the RAID.
All in all, you're probably looking at a $10K solution.
The alternatives are to:
a) divide the RAID into four separate slices and give each node its own slice of the array. This still requires a fiber channel switch, but doesn't need XSAN (you then have to work out synchronization between the different servers), or
b) Turn one of the servers into a NAS server (using either AFP or NFS) and have the other servers mount the XServe RAID over the network.
This solves the synchronization issue (there's one copy of the data that everyone sees), but isn't as fast as a fiber channel-based solution (everything has to go through that one server). It is, however, free.

MacPro RAID card - best drives?

Hey, anybody have any experience they'd like to share on a good set of drives to go with the Apple RAID card? I want to get 4 and I'm looking for maximum speed, but I can't break the bank, so no Raptors.
cheers,
-r

Well, save your $$ and just DON'T! get the Apple RAID card, then you could afford some decent drives.
600GB 10K VRs $279 x 2
OWC SSD 100GB x 2
As for what drives, bare in mind -
If you read the Apple Support Mac Pro link to RAID card FAQ:
Question: *Which drives does Apple support for the Mac Pro RAID Card and the Xserve RAID Card?*
Answer: Only Apple SATA drives and Promise 450GB SAS Drive modules sold through the Apple Store are supported for use with the Mac Pro RAID Card (Early 2009) and the Xserve RAID Card (Early 2009). Apple 300GB SAS Drive modules are supported with the Mac Pro RAID Card (Late 2007) and Xserve RAID Card (Early 2007). Drives must be either all Serial ATA (SATA) or all Serial Attached SCSI (SAS) drives. SSD drive modules are not recommended for the Apple RAID Card because these drives use their own on-disk cache and cannot take advantage of the protection provided by the battery-backed cache on the RAID card.
http://support.apple.com/kb/HT1346#faq8
People do try and use retail SATA drives, with mixed results. I have never seen anyone mix SAS and SATA.

Installing, a Apple Raid Card

Hi All
I have got my hands on a Apple Raid card (Free), I have checked it all out and it is the correct model for my Mac Pro (early 2009 i believe). now came the fun bit
I opend the MP up and installed the card as shown in the instructions (not to hard as im tech savvy) turned it all on and nothing, no apple logo, just the white screen and the little apple bing startup sound.
do I have to do any prep first to install this ?
do I have to hold any special keys down on start up ?
I dont mind having to do a full frech install ? (I was planning this anyway with Mavericks just come out)
inside the MP I already have
20gb ram
ATI GPU
Blackmagic Intensity Pro (HDMI in/out)
Esata pcie card
any help would be fantastic
