ESX 3.5 and VC maximum limits?

After reading no. of articles and discussion i get confused about maximum limit of VC to support ESX boxes and maximum limit of ESX boxes to support VM.

Will you please briefly let me know about:

a. What is the max. no. of ESX server a VC supports?

b. Whats is max. no. of Vm a ESX 3.5 supports?

Although i know that it all depends upon server load and type of applictions running over it. But just need to know in general whats limit if servers are having nominal load.

Thanks all for your valubale suggestions.

I gone through the pdf suggested by you guys and that better answred my answer. Now having two more questions at this moment.

a. Whats is answer to my question if take ESX 4.0 ?

b. As per document of ESX max. : No. of Cores per Server -- 32 and

No. of vCPU per core -- 128 .

Hence no. of vCPU i thnk so = No. of Cores per server * No. of vCPU per core

= 32 * 128

= 4096 vCPU

Please correct me where i am wrong as i know 4096 vCPU is not supported by a server (its 170 as per documents)

Thanks

About your question B, you can't multiply these maximum values if there are other maximums to take into consideration. Therefor, the maximum number of supported vCPU's per server is 192. These 192 vCPU's may be spread across a maximum of 170 VM's on a single host as long as the maximum amount of vCPU's per core (8 for 3.5U2 and 20 for 3.5U4) isn't exceeded.

In short, take into consideration all maximums, if only one maximum is exceeded, your environment might not be supported anymore.
