Hi.
We have a customer who needs more that 8 spindles within a ESXi 5.1 server to get enough IOPS out of it.
The problem is that the server hardware we are using normally (HP ProLiant DL380 gen.8) is only able to have 8 spindels connected to one controller. If you choose the 16-SFF model you have to put in a second HBA to handle the additional 8 spindles resulting in the fact that you can not combine all disks into one array.
Is it possible to combine two logical discs (two arrays of 8 disks each) into one datastore so that the load is spreaded evenly between the two arrays?
Or are there other possibilities?
Maybe anone has experience with the DL380 25-SFF (which should be capable of doing this) or maybe there is a different supported HBA from HP which is able to combine the two cages (8 HD each) into on array.
Thanks for your suggestions.
Cheers.
