D2 ?

[Igaduma]

Hi all,

Quick question,
The best bet for expanding our services now is a D2.

http://www.on-queue.com/sun/storage/workgroup/Sun_Storedge_D2_Disk_Array.html

But, i'm thinking of connecting it to a lone Ultra10 and run services from there,
but in the spec it mentioned all other types, but no ultra10.

All I understand is that it connects over the scsi3 pci card on the host, so there shouldn't really be a problem or am I missing something ?

Thanks...

think I know why, the ultra10 pci slots are 33Mhz while the scsi3 host card probably is 66Mhz,

If going for a hardware based raid setup, whats does mean in terms of CPU usage ?
Will the cpu indeed be less hammered by proc's requesting IO to disk ?

Reason:
Running an oracle db on an E-250, adding a hw based raid to that machine might raise it's cpu usage to unacceptable levels.

Geee..one should be able to TEST various setups before actually buying it

One would presume that hardware based RAID would have less effect on the CPU usage, since the RAID parity doesn't have to computed in software.

It depends on your raid layout though, are you using RAID5 or some other parity based raid? Or just RAID1 (mirroring)? If you're just mirroring then it probably won't make much difference. Annihilannic.
