Although taking another look at your question, I think I answered the
wrong question. If you create any kind of pool, backed by local disks,
files, iSCSI targets, etc, it will work as expected.
As to whether you get the same performance, my guess would be "it
depends". It depends on what iSCSI target you have on the other end,
and what fabric you have in between. Not to mention the speed of your
local drives, for comparison. The only real way to know is to run some
benchmarks of your own.
