Adding disks to a RAID 4si
Is there any advantage to either approach?
Thanks,
Brad

Re: Adding disks to a RAID 4si
Ideally you would want 4 SCSI buses attaching to the 4Si, the DS2300 has one or two buses only.

Re: Adding disks to a RAID 4si
Yes, it's unfortunate that I'm stuck with a single bus DS2300.
We are currently configured at RAID5. Since there will be more than 8 drives in the array, I have to create at least two separate, spanned arrays. I plan for the arrays to be RAID5+0.
Thanks,
Brad

Re: Adding disks to a RAID 4si
You are right in stating that our single bus is a problem, as our system is currently disk-bound. Unfortunately, there's not a lot I can do about it presently.
So, back to my original question: For RAID5+0 of twelve disk drives, is there any advantage to creating two six-drive arrays or six two-drive arrays?
Thanks!
Brad
