I think the number volumes/spindle is increasingly irrelevant in the days of multi-GB caches in storage subsystems. My SSA is one thing, a sharkesque gizmo is quite another. > There has been some discussion of relative database corruption risk > with TSM mirroring versus hardware or OS mirroring. [...] I've been feeling myself change opinion on this, recently. The reliable-storage level here is between the log and the db, no? I think I'll be experimenting with OS- or hardware-level protection the next time we have a DB architecture question. Tho, with the DS6800, it may be a long long LONG time. :) - Allen S. Rout
