Hye there, i m a newbie configuring scsi drive (and i dont know black
magic!)
We have : two scsi drives on a Aha 2940U2
one is a Viking 9,1 gig U2 (/dev/sda)
and the other Seagate 4 gig U2 (/dev/sdb)
i run htparms, and I m really surprised by the results :
/dev/sdb:
Timing buffered disk reads: 32 MB in 6.28 seconds = 5.10 MB/sec
0.02user 0.39system 0:10.37elapsed 3%CPU (0avgtext+0avgdata
0maxresident)k
0inputs+0outputs (358major+265minor)pagefaults 0swaps
/dev/sda
Timing buffered disk reads: 32 MB in 2.46 seconds =13.01 MB/sec
0.00user 0.27system 0:06.54elapsed 4%CPU (0avgtext+0avgdata
0maxresident)k
0inputs+0outputs (354major+265minor)pagefaults 0swaps
How results can be so differents ?
What things I should check ?
Is htparms a efficient benchmark ? (bonnie give me nearly same results)
What can i improve ?
Thx
