Q: Xserve 1,1 SAS controller (backplane) in Xserve 2,1 and vice versa

This might perhaps be interesting for some other Xserve users who own Xserve 2,1 with RAID controller and Xserve 1,1 with non-RAID controller and think about using VMware ESXi with the Xserve 2,1:

 

VMware ESXi does not support drives connected to a Xserve SAS RAID controller.

 

So I decided to test, if a non-RAID SAS controller from an Xserve 1,1 works in an Xserve 2,1.

 

Yes, it works without any problem - natively using OS X 10.7.5 and also with VMware ESXi.

The SAS RAID controller taken from the Xserve 2,1 also works in the Xserve 1,1 without any problem.

Tested with Mac OS X 10.6.8 Server and OS X 10.7.5

 

Of course I also tried to use ESXi on the Xserve 1,1, but (I think because of 32 bit EFI) it does not complete the boot process. The Xserve 2,1 is also not offically supported by VMware ESXi, but it works.

 

Hope this helps some other Xserve users.

    Hi,

     

     

    Yes, thanks, i'd like to try to install vmware on xserve 2.1 with a non-RAID SAS controller, i don't knew that xserve 2.1 was not offically supported by VMware ESXi, it works fine i confirm it's perfect.

     

     

    I opened a new thread because of my troubles with this famous SAS RAID controller that one who does not know how to do to forget himself even if it is not desired any raid disk. This one is in my other xserve 3.1 and your post told me that with a little good luck, perhaps it will be possible to mix these SAS RAID controller with a xserve 2.1 without Raid card ?

     

     

    When i'd do it, i'll come here back to post the result score.

     

     

    As you can see i don't speak well in English, sorry, i wish you understood what i said.

     

     

    Finally, I am looking forward to installed Proxmox in place to vmware, because it is more efficient, unimaginably cheaper than vmware, compared to vmware there is no photo finish, wins proxmox.

     

    Thanks

    Hello Jean,

     

    AFAIK there is one important difference between Xserve 1,1/2,1 and Xserve 3,1 in regard to SAS controllers:

     

    Xserve 1,1 and 2,1 both use PCI-X SAS controllers

    Xserve 3,1 uses PCIe (PCI Express) SAS controllers

     

    That's why I mentioned only, that SAS controllers (RAID or non-RAID) are interchangable between Xserve 1,1 and Xserve 2,1.

     

    Xserve 3,1 SAS controllers cannot be used in Xserve 1,1 and Xserve 2,1

    Xserve 1,1 and Xserve 2,1 SAS controllers cannot be used in Xserve 3,1

     

    So, you have been warned:

    Don't  try to use a Xserve 3,1 SAS controller in an Xserve 2,1 and vice versa!!!

    This could damage both of your Xserves!!!

    Hi,

    Oh... !!!

    Thank you very much ..."MacPro_de" because that's exactly what I would do in my 3.1 xserve !

    Any idea on the exact reference of the internal NO-raid card that I have to find thus i don't know exactly where ?

    In advance thank you, and thank you again!

    Hi

     

    It's me again, because my brain freeze, i gone to everymac.com...

     

    Here is expension slot on the exact model of my xserve 2.1, here's what everymac.com say:

     

    XServe 2.1

    "Expansion Slots:     2 PCIe 2.0     Expansion Bays:     3 3.5"

    Details:     Apple explains that this system offers "two open PCI Express 2.0 expansion slots: one half-length

    (6.6-inch) configurable slot (x8 PCI Express 2.0 or 133 MHz PCI-X) and one 9.25-inch x16 PCI Express 2.0 slot".

     

     

    And now the for my 3.1 xserve...

     

    XServe 3.1

    Expansion Slots:     2 PCIe 2.0 x16*     Expansion Bays:     3 3.5"

    Details:     Apple explains that this system offers "two open PCI Express 2.0 x16 expansion slots:

    one half-length (6.6-inch) and one 9.25-inch length".

     

    Unfortunately, I am not an expert on Apple hardware, thus is there a connection between these features there,

    and my internal SAS drive connection, as you said:

     

    "...Xserve 1,1 and 2,1 both use PCI-X SAS controllers..."

     

    thanks so much again.

    Is this thread Mac pro or xserve   ???  ... Never mind...

     

    Day tenth ...

     

    Here what i found, since hours and hours of search...

     

    Is there a what a kind soul could put these words in the order ???

    That will be very very kind of him, her ???

     

    Apple Drive Module

    Xserve Late includes three hard drive bays on the front panel. Hard drives come as modules, known as Apple drive modules ADMs, attached to carriers they are removed from or installed in the Xserve as a unit. ADMs have been available from Apple in various capacities for all Xserve and Xserve RAID models, and in multiple interface types. Xserve G and Xserve RAID use parallel ATA PATA ADMs, and Xserve G uses serial ATA SATA ADMs. Xserve Late can use SATA ADMs, and ADMs with a new, third interface type known as serial attached SCSI SAS. It is important to understand ADM forward compatibility and backward compatibility with older Xserve models, since some combinations of ADM and Xserve or RAID work properly while other combinations do not. The following table summarizes this compatibility. Xserve G PATA ADM for Xserve G SATA ADM for Xserve G SATA ADM for Xserve Late OK NO NO Xserve RAID OK NO NO Xserve G NO OK Xserve Late NO OK but not supported Xserve Early NO OK but not supported OK OK but OK not supported NO OK SAS ADM for Xserve NO Late NO OK
