Just thought I would drop this note to the list. A couple of my 50gig
drives were "repurposed" before I could run the test so this is only
a 3 disk RAID 0 stripeset. The production system will have 8 drives
(4 on each channel). I'm wondering if this will scale linearly and
give me over 100mb/sec on reads. 8-)
Details of system:
Dual PIII-450
256mb RAM
Adaptec 2940 U2W controllers (one for OS, one for RAID)
Netgear Gigabit ethernet card
IBM Deskstar 10krpm 9gig drive (system)
3 x Seagate U2W 50gb Barracudas
Redhat 6.0
kernel 2.2.12 + latest raid patches
The numbers below were attained while the system was also
running a pair of setiathome processes. 8-)
Cheers,
Chris
