RE: IBM i hosting "in the cloud"

No such thing today. But that doesn't mean it wouldn't be there in the
(near) future. The trick would be to have a local buffer (SSD or
something) that would copy blocks to the SAN server in the sky. On i,
you'd wind up with a three-tier single-level storage model, though
memory management on the i might never know. It'd wind up being a lot
like RAID controllers that don't let the memory buffer go blank until it
is written through to the disks.

No such things. SANs are attached using high-speed links. Low speed,
entry SANs use 1 Gigabit iSCSI. They're not supported for attachment to
the IBM i, though.

It only gets faster from there. 4 Gigabit FC, 8 Gigabit FC and 10
Gigabit iSCSI. Oh, and latency matters. 10 Gigabit iSCSI with 50ms
storage latency ain't fun.
