Overview
Building on a tradition of excellence, the HP ProLiant family introduces the
fifth generation HP ProLiant ML350 server. The HP ProLiant ML350 G5
server provides Dual-Core performance, enterprise level management, and
highly available redundant options in a modular server form factor.
The new ProLiant ML350 G5 is available with the Intel Xeon 5300 series
Quad core processors and 5000/5100 series dual core processors; these new
processors include a 8 MB Level 2 cache, up to a 1333 MHz front side bus,
and ultra-low power consumption providing outstanding performance and
value for the most demanding server environments.
