VMware vSphere 4.1 has been released!
This is a release that many have been waiting for. Virtualization.info leaked some early details a couple days ago.
Some of the features that are added include:
- Memory Compression – compressing RAM pages rather than using disk swapping, which will improve performance (could significantly help VDI environments)
- Storage I/O Control – VM’s with a greater need for disk resources can be given priority.
- Network I/O Control – Can better leverage network utilization by setting QoS priorites for each flow type (iSCSI, NFS, etc)
- DRS Host Affinity – VM movement can be more granular (great for limiting SQL VM movement, reducing SQL license requirements)
- ESXi will have native Active Directory Integration
- VMware vCenter Server – Will only run on 64-bit Windows.
- vStorage API for Array Integration (VAAI) – New protocol to interface between VMware and storage arrays. This can offload some storage tasks to the storage array natively.
The maximums have become larger
- 3,000 VMs per cluster (increase by 2 times)
- 1,000 hosts per vCenter server (increase by more than 3 times)
- 10,000 VMs per vCenter (increase by more than 3 times)
- Up to 8 vMotions in parallel when using 10GbE
Additionally, some names have changed:
- VMotion is now vMotion
- Storage VMotion is now Storage vMotion
- The free ESXi package will be called vSphere Hypervisor
- ESX & ESXi (paid version) will be discussed as the Hypervisor architectures
Well, I can’t wait to get it installed in the lab and give it a spin. Go to http://www.vmware.com/download to download it too.
