How many pools is "a bunch"? The ideal number of pools per server
tends to one, so reducing the number of pools might be your best

Hi all,
ISTR reading somewhere that ZFS like a generous supply of RAM.
For an X4200 with a pair of 73 GB disks (for now), what would
constitute a "generous" amount of RAM? The server currently
has a total of 2 GB of RAM, and my gut is telling me that that
isn't enough...
TIA,
N disks + 1 for parity, or
does N include the parity disk (or disks in the case of RAID-Z2)?

se notified, your data
is safe. The HW RAID, but its very nature, is a black box that we
assume is OK. With ZFS+JBOD, ZFS' built in end-to-end error checking
will catch any silent errors created in the JBOD, when they happen,
and can correct them (or at least notify you) right away.
