VMware vSphere 4.0 Update 1 Released

VMware vSphere 4.0 Update 1 ESX Release Notes
What’s New

Enhanced Clustering Support for Microsoft Windows �C Microsoft Cluster Server (MSCS) for Windows 2000 and 2003 and Windows Server 2008 Failover Clustering is now supported on an VMware High Availability (HA) and Dynamic Resource Scheduler (DRS) cluster in a limited configuration. HA and DRS functionality can be effectively disabled for individual MSCS virtual machines as opposed to disabling HA and DRS on the entire ESX/ESXi host . Refer to the Setup for Failover Clustering and Microsoft Cluster Service guide for additional configuration guidelines.

Improved vNetwork Distributed Switch Performance �C Several performance and usability issues have been resolved resulting in the following:

• Improved performance when making configuration changes to a vNetwork Distributed Switch (vDS) instance when the ESX/ESXi host is under a heavy load
• Improved performance when adding or removing an ESX/ESXi host to or from a vDS instance

Increase in vCPU per Core Limit �C The limit on vCPUs per core has been increased from 20 to 25. This change raises the supported limit only. It does not include any additional performance optimizations. Raising the limit allows users more flexibility to configure systems based on specific workloads and to get the most advantage from increasingly faster processors. The achievable number of vCPUs per core depends on the workload and specifics of the hardware. For more information see the Performance Best Practices for VMware vSphere 4.0 guide.

Enablement of Intel Xeon Processor 3400 Series �C Support for the Xeon processor 3400 series has been added. For a complete list of supported third party hardware and devices, see the VMware Compatibility Guide.

Resolved Issues �C In addition, this release delivers a number of bug fixes that have been documented in the Resolved Issues section.
