Hi --
I'm configuring a PowerEdge 2950 III with Perc 6/i.
I have
- 2x 146G 15K SAS disks
- 4x 300G 15K SAS disks
I have a RAID 1 array on the 146G disks, and will setup up a RAID 10 array on the 300G disks.
Installing XenServer hypervisor on the RAID 1 array and various VMs on the RAID 10 array.
My question has to do with the RAID "connectors."
As I understand it, Connector 0 connects to the first 4 drives (0-3) and Connector 1 connects to the remaining 2 drives.
Does it matter how the drives are distributed across the connectors? How will that impact performance and/or redundancy?
Currently, the RAID 1 drives are both on Connector 0. If I need to split them across the connectors, can I just move one drive physically to the last drive slot?
I think the Xen hypervisor doesn't do much IO itself, so maybe it would be good to leave both RAID 1 drives on Connector 0, so that the RAID 10 array is distributed across Connector 0 and Connector 1... ?
Thanks for your help!
