The more throughput that goes through a server, the more expensive its downtime. The Sun Fire V445 server is by far the best performer in its class, and the only one in its class capable of offering an average unplanned downtime of just three minutes per year.  When you can pack up to four UltraSPARC IIIi processors and new high-speed I/O into the package, you'll be even more impressed by the Sun Fire V445 server's performance.
