Greetings all. I've a question, perhaps philosophical about how much backing store you put into a machine.
Looking at a situation where we're going to be (don't ask - We're sunsetting z-series here. The decision is not logical) moving WebSphere App Server and MQ Series from z/VM to physical servers. One of these is going to have 32 gigs of memory on it. On z/VM and in VMware linux guests, I've been looking at 2-4 maybe six gigs of memory, so I've been doing 1:1/1.5:1 ratio of swap to memory. I have absoutely no idea how or where the cost/benefit peak is on backing 32 gigs of reall with swap. I'll have 658 gigs of 10,000 RPM server drives in this thing, so multiple swap volumes providing an aggregate 32-48 gig swap pool is possible, I just don't know that it is necessary. A lot of that depends of course on the application(s) being run. On a general rule though, what is best? 1:1 always? 1.5:1 always? Something else? At what point does the general rule of thumb I've been doing fall off the cliff?
