Installation Notes for This Release

Configuring Your System to Install Boot-From-SAN
For general instructions on configuring ESX Server for boot-from-SAN operation, see the ESX Server SAN Configuration Guide.

For hardware compatibility with ESX Server, see the Compatibility Guides.

Note: If you are using a preboot execution environment (PXE), a boot-from-SAN operation will fail and is not supported for this version of ESX Server. Only a local disk PXE installation is supported.

Note: Use Tivoli Storage Manager (TSM) 5.2.3 client with ESX Server 2.5.1 Service Console. TSM 5.3 client is only supported when it's installed in virtual machines.

Installing the VMware Virtual SMP Product
If you have purchased the VMware Virtual SMP product, then you can create Symmetric Multiprocessing (SMP) virtual machines, with single or dual virtual CPUs. You install the Virtual SMP product during your ESX Server installation by inserting its serial number during the Licensing step of your ESX Server installation.
