Hi!
We have several Supermicro Server Barebones (PIV, XEON) and we are wondering
about the poor SCSI performance of the RAID-Arrays controlles by the Adaptec
zero channel RAID cards.
Some servers use the 2010S, some the 2015S, some RAID1, some RAID5 arrays,
all equipped with up-to-date drives (10k rpm U320). Reading performance of a
RAID1 is about 35 MB/s seq, of a RAID5 (64k) below 30 MB/s, regardless of
the use of Linux or W2k server. Single drive performance must be twice as
that.
Has anybody a solution for this?
Regards,
Steffen Bruns
