XServe 2.1/early-2008 notes...

OK... I see a few posts on here related to my experiences with my newly-bought 2.8GHz "Early 2008" XServe 2.1... just thought I'd add to the discussion...


First topic I'll address is... I'm running the regular old "client" version of OS X 10.6.8. It works just fine if you're only planning on using the XServe like I am... as a decent platform for audio/video work and not as an actual "server". The Client version of the OS is missing all the "monitoring" and control features of the Server version of the OS, but... it actually does work. The boot process is a little strange (from my "Client" perspective) as I get to see all the Unix (?) code scolling up the window (very DOS-like) that isn't being blocked from the end-users eyes, as it is in the regular client version of 10.6.8. BTW... I started with 10.6.3 off the commercial/retail version of the OS X disc, upgraded once installed on the XServe via the "software upgrade" function when I'd ethernetted the XServe to my Airport.


Just to satisfy the questions that are brewing... I have a slew of old "legacy" audio programs that won't work without Rosetta/OS 10.6.8, and as such I'm stuck in OS 10.6.8 without upgrading ProTools, Digital Performer, and the slew of plug-in effects that I've collected. This was the "most power for the $ spent" option to keep these applications running. I got the XServe off eBay for "free" because the seller took so long to get it packaged and on it's way to me, he insisted on refunding my money. I insisted that I at least pay for shipping because I knew that was a "real" expense, where the XServe was simply old palletized-back-stock inventory to him. The auction price was $38, the shipping was $45. Still seemed like a great deal to me.


Next topic... the hard-drives... seems to be a lot of question as to what will work. I've got 3 SATA sleds in there. It only came with one, got the other 2 off eBay for something like $7 each. I've got a pile of old SATA drives in my parts bin, but... the ONLY drives that seem to work "every time" are the 2.5" size, like those you'd find in a "portable" USB hard drive. Not sure what the firmware/programming issue is, but "full-size" 3.5" drives seem to be ignored by the buss hardware. They don't even show up in Disc Utility. I'd poked around on-line and found a few comments related to this, when I COULD get my Hitachi HDS723020BLA642 2TB to mount and boot, but no other 3.5 drives would work (Seagate Pipeline, other drives that I note are 5400RPM... maybe it has something to do with the fact that the Hitachi is a 7200RPM?). Or maybe it's that only CERTAIN Apple-acknowledged bare drives will work, not sure what the list of Apple-blessed drives is. I'd start that with the Hitachi I've got. Maybe someone else has some input on this topic?


I could get any of the 2.5" SATA SSD drives that I own to work, 3 different manufacturers, each only 32 or 64GB sized. I've gotten a number of other random 2.5" drives to work, Jmicron Corp, Seagate, Toshiba. Either portable USB drives, or the Toshiba being the start-up from my girlfriend's MacBook Pro. Maybe THAT one is "Apple-blessed", don't know. Point is... it SEEMS that 2.5" drives work, for some reason. Might not be ALL 2.5" drives, so don't hold me to that. I'm going to shop for a decent sized pair of 2.5" (1 or 2TB) to install on the other sleds, we'll see how that goes)


Oh, next point... the one Hitachi 3.5" drive that's installed, bootable, reliable... is a 2TB. Seems there's an assumed "limit" on the drive size that can be used with these XServes, I assume because Apple only offered the ADMs in a max 1TB size. I can assure you, there is no such limitation. Granted, only one sample to go off of, but it is working. It's what I'm booted off of while I'm typing this.


Every drive attached via Firewire or USB works as you'd expect it to when connected to a regular Mac. They're bootable, Time-Machine-able, etc. This is actually how I initially got the XServe on-line... using a 250GB external Firewire drive that I use as a startup for emergencies/repair work.


I've got the factory installed Redeon X1300 video card on it's motherboard riser for video output. Works like you'd expect it to. Max of 1920 x 1080 on my 24" e-Machines monitor. I'm searching for a compatible PCI-Express dual output card, to give me 3 monitors... audio work uses up a LOT of desktop space. Anyone has any suggestions on a suitable video card, I'm listening. I tried an Apple Nvidia GeForce 6600LE 128MB Dual DVI PCIE I had lying around from my old Pro, but it wouldn't work.

I guess that's it for now. Any discussion/input is welcomed.

A little more playing around, more discoveries...


The max connection speed for these SATA-ADM's (Apple Drive Modules, the little trays that pop out of the Xserve that have the drives installed in them) is 1.5Gb/s. I've been getting real frustrated with the few surplus drives I have lying around, that I've tried installing, not working. Recalled a post somewhere that said the ADM's were limited to 1.5Gb. I installed a jumper to throttle-back the 160GB Seagate Constellation I've been working on, and all the sudden... it's mounted on the desktop.


1.5Gb is the top speed. That's probably why the small 2.5" "external" drives I was trying worked, they're all limited to the USB throughput of 400Mb, and as such have no need to run above 1.5Gb.


Anyhoo... just a tidbit that might be useful to someone.

Hi



I'm not at all sure of myself, for since I have my 2 xserve I never stop to search for information here and there...But I think I saw something in that ...



Have you tried, if possible??? Before installing your card: Apple Nvidia GeForce 6600LE 128MB Dual DVI PCIE...


Have you tried to remove the original Apple graphics card, the one with the only display port...


And, then, to install your: Apple Nvidia GeForce 6600LE 128MB Dual DVI PCIE...


If I do not say ********, I think this is the cause that any graphics card cannot be installed.


I have not even had time to exploit this since I have so many other problems ...


hoping to be helpful

Hello,


Whether because I too limited to 1.5GB on my xserve2.1 I am very interested in your...

Just use SAS ADMs and put SATA drives into them - then you should have the full 3 Gbps.

But I absolutely do not understand your language because I'm not a computer engineer ...

Will you explain to me as a child ??? That would be very nice of you. Thank you.

AFAIK Apple Nvidia GeForce 6600LE 128MB Dual DVI PCIE comes from an Apple Power Mac G5 Late 2005 and will not work in Intel Xserves, because the Apple Power Mac G5 has OpenFirmware (so the 6600LE has a BIOS for OpenFirmware - my experience is, that Intel Xserves will not boot at all with such a card) and Intel Xserve has EFI.


What you would need, is a card, that supports EFI.

Only these two cards will fit into Intel Xserves and work out of the box:


Apple Nvidia GT120 video card

(Apple OEM from Mac Pro 4,1 - this card only supports 64 Bit EFI, so it will work in Xserve 2,1 only)


Apple ATI/AMD Radeon 2600XT

(Apple OEM from Mac Pro 3,1 - this card supports 32 and 64 Bit EFI, so it will even work in Xserve 1,1)


Both cards are slim enough to fit into the standard PCIe slots and both cards do not require to get additional power with a cable directly from the power supply. (This is helpful, because such a cable is not available in Xserves.)

Haven't tried a Radeon 2600


nVidia GeForce 7300GT 256Mb (Mac version) didn't work.


DUAL MONITOR VIDEO CARD ATI RADEON x1300 256MB ATX PCI-e 16x DUAL VGA CABLE, despite being a "Radeon x1300", it didn't work.


PNY Nvidia GeForce 7300GT (PC version) didn't work.


631-0064 - Apple Nvidia GeForce 6600LE 128MB Dual DVI PCIE Video Card - 630-7132 didn't work.


All those I either had already, or found cheap on eBay. I FINALLY broke down and bought an Apple nVidia GeForce GT120 dual output card... and it works. Be sure you have a "Thunderbolt" Mini Display Port to VGA adapter. The regular "mini display port" adapters are not the correct ones.


I've got 3 1920 x 1080 monitors running. I could probably the monitors at "higher" res by using either of the pair of outputs off the card, but 3 HD monitors will work for my needs. Also, I'm running out of space on my wall for displays. (HA!)

I've tried 2 other Seagate 5400rpm 2TB drives with didn't work. I have 2 different Hitachi Ultrastar 7200rpm 2TB drives running in 2 of the bays on ADM sleds. All works well. (the third bay has a 250GB drive with a couple different OS versions on it (10.6.8, 10.5.8, both "client" versions)


I "suspect" that 4TB drives will work, but haven't had the $ to investigate this yet. I'd also point out I have absolutely not "technical" reasoning behind this statement, but I figure if the 2TB drives work (and they aren't supposed to), why shouldn't the 4TB drives work?

Yes, that's exactly, what it means.


Apple basically offered three different types of Drive Modules for Xserve (ADMs):


1. IDE (only for Xserve G4 and Xserve RAID)

These ADMs provide an internal 40 pin IDE cable and a 4 pin power connector. Because you have an Intel-based Xserve, they won't fit into your Xserve and also not work at all, so we don't care.


2. SATA (for Xserve G5 and all Intel-based Xserves)

Internally these ADMs provide a SATA connector and a SATA power connector and AFAIK all SATA ADMs are limited to 1.5Gbps.

To my experience Hitachi/HGST drives mostly work out of the box and will automatically select the correct speed for the SATA-1 interface of the Apple ADMs.

All Seagate and WD drives, that I have tested here, needed to be forced down to 1.5 Gbps using a jumper. Without that those drives won't be recognized.

Another issue is, that older SATA-ADMs from Xserve G5 might not be bootable in Intel Xserves.


3. SAS (for Intel-based Xserves only)

Internally these ADMs provide one transluscent SAS connector cable with a combined SAS/power connector.

One advantage of this type of ADM is, that you can install either SAS drives or SATA drives into them and that they support 3.0Gbps.


These are some Apple part numbers for SAS ADMs:


620-4575

620-4086


Just use Google to find more information.


My experience is, that drives larger than 2 TByte won't work in any of the ADMs.


Hope, this helps.
