hi, I want to deploy lustre on a medium scale cluster(nodes about 200''s).We have to make decision on choose OST storage device, sata raid or scsi raid? FC-array is expensive for us. so lustre + scsi or lustre + sata ? Especialy I need some advice from CFS or any other successfull story on deploying lusre cluster.
