Vmware ESXi - hardware selection to backup
Posted on 2008-11-03
I am going to throw a consulting question which I think will be useful for me and also for anyone looking to implement a virtual solution like us (small/medium business solution). I hope your answers will be a guide from start to end for anyone looking to virtualise and I am sure we can build our base on those.
We are looking to virtualise 3 servers (Web, DB and file server) initially with the future potential of adding 3 more servers (including Exchange and AD). The existing loads on these servers are as follows
Web server Data size :10 GB, Processor usage: 20% normal and peak at 70% (peaking for 30 minutes daily)
DB server - Data size :15 GB, Processor usage: 50% normal and peak at 90% (Peaking for an average 3 hours daily)
File server - Data size : 100 GB, Processor usage: 60% normal and peak at 80% Peaking for an average 3 hours daily)
The budget we have currently available to buy a server, virtualise (ESX3) or ESXi, SAN, backup or DR solution is £6000. (Plus an addition of £1000 in case..)
Please find the list of questions below. I just split the questions to make it clear. Please let me know the approximate pricing for each component as well.
1. Do you think the above budget will be enough for this project?
2. What spec of servers we will be looking for based on the above requirements?
3. Is it wise to put all the above servers into one physical server or go for 2 servers?
4. What type of SAN you will recommend (max size we are looking for is 2TB)?
5. What connectivity on the SAN (Iscsi or Fibre)?
6. What gigabit switch to use to connect the SAN to the host?
7. Can we use our existing layer3 switch?
8. What platform to use (ESX3 or ESXi)
9. What backups and recovery method to choose? (we would like to have both Vm machine level and file level backup and restore, I dont know which hypervisor (ESXi or ESX3) fits for this purpose?
10. What kind of monitoring tools we use for the Vms?
