Hi all! I have a smaller Lustre system that just experienced a RAID controller failure. We''re going to try to rebuild better. We don''t have a HA requirement. MDS: ATTO 16 port SAS RAID controller 10 73 GB 15k SAS drives, 8 in RAID 10 plus 2 hot spare 8 cores, 16 GB memory 2 - OSSs: Areca 8 and 16 port RAID controllers 500 GB Hitachi SATA drives on both 4 cores with 8 GB memory We''re using Intel Pro/1000 PT dual port cards bonded for the OSSs and a single Pro/1000 on the MDS. Suggestions? Previously we were using an Areca controller for the MDS but it seems to have trouble under load. They do ok for the OSTs - around 275 MB/sec sustained writes. Is anyone using a similar configuration? Thank you, Dan
