ZFS Large scale deployment model
We have a virtualized environment of T-Series where each host has either zones or LDoms. All of the virtual systems will have their own dedicated storage on ZFS (and some may also get raw LUNs). All the SAN storage is delivered in fixed sized 33GB LUNs. The question I have to the community is whether it would be better to have a pool per virtual system, or create a large pool and carve out ZFS

By any chance, has this been discussed or considered before?

Migrating from key system to asterisk
I currently have 4 lines coming into the house. We currently have an Avaya standard analog key system which has served us well, but running extensions is a major pain and requires a dedicated run per extension. I have ethernet run throughout the house though. The first two lines are "home" lines, however line1 I use for my consulting during the day, and line2 is used by my wife for
