MSA Model to use for Clustering

Jiten Joshi — Fri, 06 Feb 2015 12:40:22 GMT

Hi ,

I recently purchased MSA20 for Clustering 2 HP servers, which later I came to find out that MSA20 does bot support shared disks.

I would like to know which MSA to buy which supports shared disks, and probably in which I can use the same hard disks.

Please assist.

Thank you

hi,

you're probably looking at an msa60 if you want to re-use the disks , see here :-

Hello,

you can take the MSA2000sa. MSA60 or MSA30DB are not supported for clustering.

Best regards,
Patrick

The MSA30MI (Multi Initiator) uses a special I/O module that allows shared access from multiple HP-UX servers (if that was meant by "2 HP Serves").

For x86, you need a different technology like SAS, Fibre Channel or iSCSI.

I am using Windows Server 2008 Enterprise Edition for the two HP DL380 servers. And it is installed with HP 6402 smart array controller, which has SCSI connectors. .

I need alternate MSA solution which support SCSI connections and probably if I am able to use the same MSA30 hard disks. To avoid extra costs.

Please help.

Thanks

Sorry, no support for clustering on parallel SCSI interconnects.

And you can't use this type of backplane RAID-controllers for clustering:
- can't turn off the termination
-- you now have 3: SA-1, SA-2, MSA
- can't change the SCSI address of one of the controllers

Thanks,

So which MSA model would you recommend? considering my existing setup.

What generation are those DL380 servers, how many and what type of PCI slots are free and how much data do you need today and in the future?

If you can get your hands on a MSA500 G2, you can use the MSA30 disks and the Smart Array controller with it.
It's a shared storage that's accessed through SCSI.

Ohter MSAs like MSA1000, 1500 and 2000 are acessed through FC or iSCSI.

I don't see support for W2008 and wonder if the box even works with Windows 2008 clustering?

Ahhh, nop. Also only seems to be supported only with Smart Array 642 and Smart Array 6i adapters, so forget what I said.

I am using smart array 6402 array controller on the servers
