Hi,
I have a HSG80 with a single controller with 512MB cache direct attached
(without a switch/hub) to a DS20E (dual 666MHz).
When initialising a raidset on the HSG80 with 6 disks (72GB 15K RPM)
over 6 ports/channels I don't get more than 4200KB/s read and 820KB/s
write throughput per port (vtdpy, display device).
Also when accessing a diskset like this I have never been able to read
or write more than 20~30MB/S.
Shouldn't this controller be capable of more than this, with these
disks?
OS: Tru64 UNIX 5.1B PK3
FC: KGPSA-CA : Driver Rev 2.10 : F/W Rev _3.91A1(2.20A0)
emx0: Using console topology setting _of : Loop
HSG80: Software V87G-4, Hardware E12
PORT_1_TOPOLOGY = LOOP_HARD (loop up)
