Hi all, I'd like to first introduce myself as a Lustre newbie who is interested in implementing Lustre on a small cluster to improve on NFSv3 limitations. Let me describe my setup:
I have 11 execution nodes (104 cores total) which are each connected via 1GE to a fileserver (using 4x1GE aggregated link). The fileserver currenty has a 4-disk 1.5TB RAID10 array as its main storage, plus a 2-disk 2TB RAID1 array, and a 4-disk 4TB RAID6 array. Whilst the RAID10 array must stay intact (due to system OS, shared application partitions etc etc), I'm looking to possibly reconfigure the 6 (2TB) disks into arrays suitable for serving 3 Lustre filesystems (/home, /storage, /scratch). This would be with a view to having the MGS and 3 MDT partitions on the main storage, with OST partitions spread across the 6 disks. The question is, what is most efficient? Given that my RAID controller is hardware-based (Dell PERC6), would it be better to split my 6 disks into multiple OSTs, or keep them as one big lump? I've not seen a discussion of this in the Lustre doc, so I'd like to gather a few pointers/opinions, if I may?
