@wrx7m said in VMware Host Cannot Connect from vSphere Client: Could also be an issue if a vendor-specific ISO was used to initially install ESXi. I ran into a similar problem with Dell; I had to get the Dell ISO from their downloads for the specific server model/service tag. For 6.0 this is fine (you'll use this to get ASNC drivers). You can also add the dell VIB depot to get them this way also. For 6.7 Dell has (thankfully) stopped shipping ASYNC drivers and moved 100% to inbox. It's all for 3rd party management VIBs. Honestly I've seen 3rd party VIBs be a culprit for updates before. I'd make sure you are updating the BIOS/FIrmware also when updating ESXi (People forget this sometimes).

Good! What CPUs do you have in the R720 today? 1 or 2 CPUs? Do you want the new ones to be faster or just capable of running more VMs? I have 2 x E5-2609 CPUs in each server. I would like faster, but more VMs would be the priority. The E5-2609 CPUs are at the low end of what was available at the time so no problem there. Actually, are you looking to keep the old servers around for testing and such? In that case you could just drop in refurbished CPUs that are faster and/or has more cores for very little money. If the server can take E5-2600 V2 you can get up to 12 core CPUs. yeah, but Windows licensing is an issue, assuming multiple CPUs... for a test server, not likely worth going over the 16 cores. Not to mention the test server might require licensing (if needed beyond the 90 day test period for something). Two 8-cores would be an option. For instance two E5-2690. They are 2.9 GHz base frequency and have 8 cores. About $100 each when buying refurbished. About 50% faster per core (2609 have no turbo) and about 3 times faster multicore performance. Has more cache and faster memory transfer speed. Was a very high end CPU at the time. Was listed at $2000 while the E5-2609 was $300. The fastest 8-core E5-2600 V2 CPU is the E5-2667 V2. 8 cores and base frequency of 3.3 GHz. It will likely also be an option for the R720XD. V2 uses 22nm technology so uses less power with the same clock speed and can fit more cores or run higher frequencies.
