DL 585 G5

[nkv]

Hi everyone,

I have DL 585 G5 quad core processor (16 CPU x 2.411 gHz Quad core AMD opteron processor 8378) and 64 GB RAM hardware. We are planning to design a ESX cluster with 5 hosts with this configuration.

Please help me understand .

Question 1: A virtual machine is allocated a count of vCPU and RAM on what basis (is it like VM type - db, web, file)

Question 2: How many virtual machine can i host on this cluster if i am assigning 1 vCPU per virtual machine and 1GB RAM.

Question 3: What is total MHz capacity I have from 1 host

Any help would be appriciated

Thanks

Hello and welcome to the forums.

Question 1: A virtual machine is allocated a count of vCPU and RAM on what basis (is it like VM type - db, web, file)

Its entirely up to you. You can allocate X number of vCPUs and X amount of RAM to each virtual machine, and if you get it wrong or the requirements change then you can change them again.

Question 2: How many virtual machine can i host on this cluster if i am assigning 1 vCPU per virtual machine and 1GB RAM.

This depends on several factors, but generally speaking the rule is 4-6 virtual machines per core.

Question 3: What is total MHz capacity I have from 1 host

(16 * 2.411) = 38.576 GHz

If you have 5 of these HP DL585s in a cluster, then you are in good shape. The bigger part of this equation is what are you going to do for storage? Without adequate disk in place, you aren't likely to hit the big numbers of virtual machines.

Good Luck!

Welcome to the Forums - And to add to vmroyale - as he indicated you will have plenty of CPU cycles but you will need to pay attention to storage and I would add the other limiting factor tends to be memory - you max out your memory before you max out your CPUs - do not get me wrong ESX/ESXi does an excellent job of economizing on how VM memory is allocated which allows you to overcommit memory but it is memory and disk where people typically hit perfomance/consumption issues - at least that has been my experience
