MFSYS35 with external sorage unit.

[MSmit25]

Hi,

I have a MFSYS35 with a single SCM module installed in it. This has the shared LUN feature activated.

This is located at remote site so I cant test this so need advise before I go.

I have been given a HP P2000 storage unit that has dual SAS controllers to connect to the MFSYS35. I was also given a PCI HBA card with SAS connectors, which OI assume I cant use in the MFSYS35.

Can I connect the P2000 to the SAS port on the SCM? I realise that as I have not got two SCM's installed that the 2nd SAS controller on the P2000 will not be used.

I then assume I have to configure the RAID on the P2000, but will I then see this in the Modular Server Control management interface? And can I then assign this to the storage pool I have already?

Will this external enclosure work with the shared lun feature?

Thanks.

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.

See the http://www.intel.com/support/motherboards/server/sb/CS-029660.htm Promise* VTrak Connection Guide for more information.

Can a Shared LUN be used with external devices?

A Shared LUN can only be used with virtual drives within the chassis.

Thanks,

yikes that is going to cause me issues. This has two blades installed with XEN server installed on them. The plan was to create a new shared LUN using the new drives in the enclose so that we can use this for fail-over. :-(

So i guess my only option if i want to use a shared LUN with this chassis is to use ISCSI, unless anyone knows a way around this limitation?

Hi,

interesting question. I am using vmWare on our two CMs, and would face the same problem "shared LUNs".

I would add:

could a storage offer two LUNs for the same VDD instead?

That would move the responsibility to the storage system?!just an idea...

I have taken a different approach:

We are currently swapping all drives to 1800 GB-Drives and that will give us enough storage.

see my post

Test have finished and conversion starts this week.

Just a though...
