VMware vSphere is the latest release of its popular virtualisation software.
vSphere will only be able to run on 64bit hardware and some of its additional enhancements will only work with a small number of processors like the Nahalem 5500 series. With these considerations in mind upgrading from your existing virtual infrastructure will require some detailed planning to ensure a successful migration to vSphere.
Some of the enhancements that come with the latest version are:
Host Scalability:
64-bit VMkernel
512GB
64 logical CPUs
256 virtual machines per host
Virtual Machine Scalability:
8-way Virtual SMP
256GB RAM
Hardware Version 7
• New virtual devices
• VMDirectPath I/O
• Hot plug support
In addition to the above vSphere will also include:
• SCSI-3 compliant meaning you can install Windows Server 2008 MSCS
• IPv6 is supported
• vNetwork Distributed Switches
