On the first birthday of AMD's Opteron, Hewlett-Packard has become the first major vendor to offer a four-processor server based on the 64-bit chip.
HP's new ProLiant DL585 is a 4U, Opteron-powered sister product to its Xeon-based DL580. The server will have two more PCI-X than the 580, and will support up to 64GB of memory -- 32GB more than the DL580, according to HP Group Manager for ProLiant Systems Steve Cumings.
Because of differences between Opteron and Xeon, however, the DL585 will not have the memory protection features of the Xeon system. "Because of the Opteron architecture, you have the memory controller on the processor itself, so it's not actually possible to deliver Hot-Plug memory in the way we've done it with the Intel processors," Cumings said.
The DL580's Hot-Plug feature lets the system replace a failed memory unit on the server, Cumings explained.
