Hello folks,
I am about to purchase a new server with a raid storage system and I would like
some advice to see if there are any many problems going for (S)ATA over SCSI.
The system is going to be small system 1 server (V240/V250/V440) and 1 RAID box,
since money is a problem I am considering a ATA system since you can get a lot
more storage for the money.
My two question is there a real difference between going for a RAID box full of
(S)ATA disks or SCSI disk. I see that rpm on SCSI are 10,000 rpm over the 7,000
rpm on the (S)ATA disk, but is that going to make a big difference!
And does a fibre-channnel make a lot of difference with the above setup as it
is.
Possibe Storage Solution:
Sun StorEdge 3310 12x73GB Ultra160
Apple XRAID 7x250GB ATA
EcoStor (SweetStor) 7x250GB SATA
On our new XRAID running (RAID 5) system I get about 70M per sec
(machine not is use)
% timex -p dd if=/dev/zero of=/m/disk/tmp/newBigfile1gb bs=10240 count=100000
100000+0 records in
100000+0 records out
real 13.80
user 0.40
sys 9.10
Any comments,
Cheers
Andrew Watkins
