HP Superdome, LVM Striping, and EMC
Please lend me your thoughts on the Efficacy of LVM striping with:
large Oracle BC (buffer cache),large Unix BC, huge EMC BC, and ultimately,
no control over actual placement on the physical drives on EMC (Raid 1)?
stats: 1.2 TB DB, HP Superdome, 18 CPU, Oracle 8.1.7
Corporate environment: over-taxed SA's, dis-interested storage admin group.
How to measure the effectiveness of an LVM striping configuration when our
environment has the above-mentioned characteristics?
It seems to me that any potential benefit of striping would NOT be gained by
LVM striping, that in fact the LVM striping would become an unnecessary
layer of complexity. Initial comparisons of Oracle and SAR don't point to
anything specific, either because of inadequate stress and volume testing
because we don't have collaboration between me (dba), unix SA's, and storage
group despite diplomacy.
Please send wisdom: fight for my rights or take the storage and run?
