Hi,
I have been asked, which one of the two I would chose for two MDS
servers (active/passive). Whether I would like to have SSDs, maybe two
(mirrored) in both servers and DRDB for synching, or a RAID controller
that has a 15K disks. I have not done benchmarks on this topic myself
and would like to ask if anyone has an idea or numbers? The cluster will
be pretty small, about 50 clients.
Regards, Michael
