Hi all,
I have been doing some performance testing on my file server, the specs
of the machine are:
Compaq Proliant 6500
Quad Pentium Pro 200/1MB cache
2GB Ram
2 x 2/DH Hardware RAID controllers
1 x Emulex LP8000 Fibre Channel controller
Dual 10/100 NIC (Intel)
Fibre 1000 NIC (Intel)
(All PCI slots are 32-bit/33 Mhz.)
This is connected, via a Storageworks San Switch 8 (basically a Brocade
Silkworm 2400) to two :
Storageworks 4000 fibre channel enclosure, each with 12 x 36GB U160,
10,000rpm drives arranged as 2 logical RAID 5 drives.
The box is running Debian Sarge, fully patched upto date.
I realise the hardware is not exactly top of the range, but I thought
I'd see what it would do.
OK, so I have run a few tests, but settled on dbench as it's *really*
easy to use :-)
I am seeing about 54MB/sec when run on the fibre connected drive(s), and
about 90MB/sec when using the 2/DH controllers...this seems a little
odd, as the 2/DH are only supposed to be 40 MB/sec interfaces, whereas
the LP8000 is a 1Gb/sec card - I would expect to be seeing closer to
100MB/sec from the fibre devices ....
From local, 2/DH filesystems:
bungo:/tmp# dbench 2
2 clients started
0 62477 90.67 MB/sec
Throughput 90.6613 MB/sec 2 procs
From FC connected:
bungo:/export/iso# dbench 2
2 clients started
0 62477 44.23 MB/sec
Throughput 44.2259 MB/sec 2 procs
Is there anything else I can try, or do these figures seem reasonable to
everyone?
Cheers,
I would ask your question on the debian-isp list. You are more likely
to find people there that have dealt with this level of hardware.

Thanks ... I'll try that..but there must be someone on this list with
similar hardware - it's not *that* old or obscure surely?
Cheers,
Pete.
