Can anyone suggest me on what is the vsphere 5 infrastructure setup required to host arount 1200 virtual servers. It will be helpful if anyone can give informations like how many hosts required, rocommended physical server model to host ESXi, how many clusters , how many vcenter servers required to manage this infrastructure, how many VM's in one ESXi , recommended LUN size, how many VM's in one LUN. Can anyone help me on this.
This is a very big question... 1200 virtual machines isn't small and calculating this isn't something anyone will just answer as there are many requirements which are needed to be known.
- What type of virtual machines will you be running (Linux/Windows/mixed, how many vCPU's, how much RAM, how much diskspace,...)
- Regarding storage: do you have a budget to run this on as this will define what type of storage you will end up (iSCSI, Fiber, SATA/SAS/SSD,...)
- Regarding hosts: again this depends on the budget, you can buy hosts with 256GB RAM or 1TB RAM, which type of NIC's will you use (Gbit, vs 10Gbit),...
You will have to do research on storage and hosts and match what you prefer. You could go for DELL EqualLogic with DELL servers but you could even go for HP storage with HP servers or a mix (like HP servers and NetApp storage,...)
How many VM's you can run on 1 host depends on the above, the same applies for 1 LUN (IOPS based, disk usage based),...
As you can see there are many requirements/factors you have to keep track of and I would suggest hiring a consultant for this type of job. I don't think this is something anyone here will be able to answer very easy.
Easy answer to all your questions: it depends
If you want to know start with VMware Capacity Planner to figure out how many resources are needed. You need to be a VMware Partner to access this software. So hook up with one locally.
