my questions is : if i need to deploy 170 virtual machines and i need HA. is it possible to deploy all 170 vistual machines on one ESX host and in case one ESX host is down. all virtual will migrate to another ESX host.
what will be the traffice effect on the network card. e.g all of the users are using all virtual machines. what will be the performance on ESX host. what will be the hardware requirements for ESX host for around 170 virtual machines. or how many ESX host required to accomodate 170 virtual machines.
No, the current limit is 160 in a two host cluster.
but why would you? why not buy three of four medium sized servers instead of 2 giant boxes? this way you will increase availability and flexibility.

It is not possible (as in supported) according to the config maximums as Duncan pointed out, doesn't matter how many vCPU's per physical core you run, "Virtual machines per host in HA cluster with 8 or fewer hosts for vSphere 4.0 Update 1 = 160". Scaling out with more than two hosts in the cluster is as suggested the best idea to fit 170 machines into one cluster.
If you find this information useful, please award points for "correct" or "helpful".
No, i recommend you to use tree ESX servers into a HA cluster, and segment the VMs in 500 GB LUNS.

you can use RHEV that is bare metal installation and same time how much
process your looking pre guest and which hardware your looking buy!! if
have hardware in place what i suggest use RedHat HPC solutions with RHEV
it give more better performance and less in cost.
