VMWare said Tuesday that SAP will support its software running on VMWare's ESX Server, in 64-bit Windows and Linux environments.

SAP will offer companies who deploy ESX Server support for "all stages of the software lifecycle, from development and test to production," according to a VMWare statement.

VMWare also said that server products from Fujitsu-Siemens, HP, Dell and IBM have been certified for running SAP software on VMWare.

The company's newly strengthened alliance with SAP comes at a time when it remains the dominant market leader for virtualization but is seeing competing products from the likes of Sun and Oracle emerge.
