Ata over Ethernet

When one is working with large numbers of devices, one always hits the
MTBF wall. Even if an individual device has 10,000 hours, if you have
10,000 of them, you will be replacing one every hour. After talking to
the folks running a very large compute cluster with thousands of
processors and terabytes of memory, they replace hardware daily. The
trick is to be able to stay in production while this is done. In the
case of the cluster, the run does not depend on the survival of any one
node. In the case of storage, the key is raid, hot swap, and online
spares. If you shove in a few 250GB sata drives a year, so what? Price
of doing business! The important thing is staying on line.
