Advanced Micro Devices Inc. has persuaded three more top OEMs to use the Opteron, but it has a long way to go in persuading many big-enterprise customers to switch from systems that use Intel Corp. processors.

To help make that leap, AMD has laid plans to enhance the processor and at the same time has enlisted server makers Hewlett-Packard Co. and Sun Microsystems Inc. to expand their Opteron-based offerings with existing chips.

HP this week will unveil a Linux server cluster that includes the LC3000 Series, which features the Opteron-based two-way ProLiant DL145 server. The cluster is targeted at high-performance computing applications. In addition, HP, of Palo Alto, Calif., will announce the availability of its ProLiant DL585 system, which features four Opteron processors.

Later this year, HP will ship more blade servers powered by the Opteron, and next year HP will expand its Opteron offerings further, officials said.
