The software will be able to handle more demanding workloads than previous versions.
The 4-Way Virtual SMP (symmetric multiprocessing) product will be available in the second half of 2005 as an add-on to VMware ESX Server, with pricing to be announced at the time of availability.
Ed Bugnion, chief technology officer at VMware, said, "Our users enthusiastically adopted our 2-Way Virtual SMP feature to run applications requiring multiple processors in VMware ESX Server virtual machines.
"As multi-core processors become standard, scalable Virtual SMP will become an essential part of our users' virtualisation strategy. The 4-Way Virtual SMP allows users to standardise on a virtual infrastructure in 2005," he said.
The 4-Way VMware Virtual SMP follows VMware's first delivery of 2-Way VMware Virtual SMP in 2003.
