Do I have to add a mezzanine card to each compute module?
One Dual Gigabit Ethernet I/O Expansion Mezzanine Card AXXGBIOMEZ is required for each compute module that needs to access the second switch.
What kind of compute modules are in the MFSYS35, and have you added a mezzanine card to each?
I figured out that was what we needed. I have been advised we can't get the cards so had to go with the SAS unit in the end. Do you know of any documentation on how to configure SAS expansion devices to work with this chassis? I was hoping that i would see the LUNS from the expansion unit on the MFSYS35 modular server control but i don't. Does this just pass through the SAS connection meeing that allocating hosts must be done on the external device?
You won't see LUNs from an expansion unit in the modular server GUI. It will only pass through commands.
How do I configure my external RAID subsystem through the GUI? Do I have to attach it to both SCMs if I run in dual-mode?
The external storage array management software must be used to configure all drives within the array. Please see the tested hardware and operating system list (THOL) for the list of peripherals that can be attached to the external SAS port. You must order external RAID subsystem units with a second controller to be able to attach to both SCMs simultaneously.
How do I connect external devices to the SCM?
View the back of the chassis, and select the SCM. Select Actions - Expansion Port. Choose the module that will use the external device, and click Apply.
