I am an owner of 3 PE2650, and am also very concerned about the speed of
my Perc3/QC RAID5 array.
Is this very much slower then the Compaq RAID arrays?
Anyway to make them work better or buy something to rival the compaqs?
I really like the PowerEdge but its RAID capabilities are really
stopping me from buying more Compaqs...

Subject: speed of RAID 5 array
PE 4600, redhat 7.3 (2.4.18-4smp kernel), dual 2.8GHz xeons, PERC3-QC
card, 8 x 73GB SCSI drives in a RAID 5 config (attached to the PERC3
im running a benchmark on the RAID 5 array. the package is bonnie++
(v1.02c). test results on the RAID 5 array are:
46MB/sec write, 24MB/sec re-write, 85MB/sec read.
now, im not complaining cause that is faster than our network can go
anyway, but is that a good speed for the hardware i have?
just curious, thanks!
