ESXi 4 IS the Standard now:
I have to explain that on almost weekly basics to my customers and prospects, that, the ESXi 4 version of VMware is the version that they should adopt now as the ESX 4 version with the COS will disappear. The ESXi 4 version of VMware Hypervizor has all the features of ESX 4 and has thinner footprint. Then it only depends the licensing you purchase with the package. It starts for the SMB with VMware Essentials or VMware Essentials Plus.
Then on the same blog earlier this year You can see the detailed info about the ESXi 4:
- The functionality and performance of VMware ESX and ESXi are the same; the difference between the two hypervisors resides in their packaging architecture and operational management. VMware ESXi is the latest hypervisor architecture from VMware. It has an ultra thin footprint with no reliance on a general-purpose OS, setting a new bar for security and reliability (learn more).
- In the future, ESXi’s superior architecture will be the exclusive focus of VMware’s development efforts.
New and existing customers are highly encouraged to deploy ESXi. Many Fortune 100 companies have already standardized on the ESXi platform.
So for me, I guess the best now is to deploy the COS-less versions of ESX …
The ESXi 4.
