Hi all,
I will shortly be installing a DS3400 (FC front end and SAS 300GB drives in the enclosure), and I have a number of questions I hope somebody can help me with.
1. When I create the RAID 5 set, and specify the Stripe size, what shoudl I use, 16k,32K or as big as it can go?
2, I need to create a VM for a file server that will have around 1.5TB of data on it. Do I create a RAID group using 6 drives and then create 1 LUN on it, or do I create multiple LUNS on the one RAID group, and split my VMDK's across the LUNs?
3. Or do I create up to 2TB in the RAID 5 set, create one massive LUN, and then create this as a VMFS file system?
There appears to be various options, and I am not sure what is best, both from a "best practice" and from a performance issue. I am particulary interested in the backup performance of the final option.
Thanks!
