170 virtual machines HA requirements

[noor1027]

Dear all,

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.

Thanks

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.

No, i recommend you to use tree ESX servers into a HA cluster, and segment the VMs in 500 GB LUNS.

Regards!!!

170 machines is a lot...I mean a lot...and you don't mention what your server specs are. I think you might have to have a farm of servers. To have HA for virtual machines, you normally have a large storage SAN on which you deploy the images, then you mount that SAN to multiple servers. The servers would run something like VMWare with VSphere, and they can handle the failure of one or more servers to migrate the machines to another server within seconds (or less). VMWare has some white papers and information on this. Other companies have similar products. So can you have HA for a number of VM's? Yes. Can you do it cheaply? Not easily, you'll need a server farm and shared backend storage plus the licensing costs of the software. You can't do it on one server, and your question sounds like you wanted it on one server. I don't know where you could run one server running 170 machines simultaneously without killing it unless you have a server in the back room of the R&D department of the DoD or IBM...

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.
