Re: performance diff if move 1 of several app data libs to asp 2



fixed

Why not simply move the disks into ASP1?

I agree, but in this case, there "old drives" in both asps, of
several sizes, but no "slow/large" drives. The 2nd asp was not a part of
the original setup in '08.

It really depends on the disk controller, number of drives, drive types
and speed, and size of drives.

4 2T SATA drives at 7200RPM will be slow compared to 8 320GB 15K RPM SAS
drives. SCSI performance can really slow things down compared to SAS.

Most Archive ASP's I have seen have been of few large slow drives to hold
lots of rarely used data. Would not put prod DB's there.

We want to balance our asps so asp 1 not so full, but don't want
performance degraded.
If moved, user apps will be reading data from both asps. Asp 2 was orig
set up years ago for old rarely used data.
