ESX 3.5 U3 has been released. You can read the release notes here . There were a few significant updates in it that Commercial Customers have been asking me about.
- The vCPU limit per core has been raised from 8 (or 11 with VDI) to 20. This means that you can run vCPU’s 20x the number of cores in a box to a host limit of 192 vCPU’s today or 170 VM’s, whichever comes first.
- Guest operating system support added for Solaris 10 U5, Ubuntu 8.04.1, and RHEL 4.7. New OS support is always good for customers and always something I get asked about.
- Numerous hardware additions to the HCLs .
Great stuff added, of course I understand some customers are not on the bleeding edge and hold off before updating which I completely understand (especially after the licensing bug). For those customers, watch for a follow up post on the benefits of Update 2 (which was huge). Now may be the time to consider Update 2 for rollout if you have not already.
