VM with a need of huge ressources?

Jump to solution

Hi all!

I am on a new project and the specifications for one server are:

- server with 1 cpu quad core 3Ghz and 16Go of RAM

- Red Hat AS 4 update 6

- Oracle 10g Release 2 (10.2.0.1.0)

Do you think I can run this OS on a virtual machine? If so how many quantity of RAM I should attribute to the HOST? I think I will need other VMs for this project but which need less ressources.

When it is said 1 cpu with 4 cores, does that mean I have to give 4 cpu to my VM?

Thanks,

Alexa

Hello,

Oracle does not officially support their product on VMWare Server. Yes it will run.

Redhat OS AS 4 will will run just fine and is supported on ESX 3.x and is experimental on VMWare Server 1.04

How much memory depends on the DB size and apps it will run.

1 physical CPU package with 4 physical cores inside.

I have been wrong before but you be the judge.

Redhat supported hardware list

VMware


874

ESX Server 2.5.4 Server

RHEL4.5 for i386



875

ESX Server 3.0 Server

RHEL4 Update 3 for i386



876

ESX Server 3.0.1 Server

RHEL4.5 for x86_64



877

ESX Server 3.5 Server

RHEL4.6 for i386



878

ESX Server 3.5 Server

RHEL4.6 for x86_64


I don't see any VMWare Server 1.0.x here

Oracle's support agreement states that when running Redhat linux AS 4 and 10g and the hardware is on the Redhat supported hardware list it is officially supported in the agreement. Otherwise you may get the not officially supported mode.

This does not mean he will not get support, it just means be careful and read the fine print.

clip of the agreement

Enterprise Linux Basic Support will be available for an additional four (4) years ("Extended Support") 3, but will be limited to all features listed above except hardware certification. During the Extended Support period, Enterprise Linux Basic Support will be subject to an additional fee.

I use ESX 3.02 not VMware server.

Is Oracle 10g supported on ESX 3.02?

Why virtualize this if you don't have big ESX servers already?

I am very surprised you would ask that.

I can think of many reasons. Can you?

This is a new project... so I find really interesting to think about virtualisation...

HA DRS... VMOTION...

Moreover I work on a VMware DRP between two offices... It would be great to have a DRP for this critical project... and I have "just" to buy two servers for ESX and add it in my VC.

I heard Oracle is supported on VMware ESX but VMware is neither certified nor supported by Oracle. Statement from Oracle is: IF a

problem (occurring on VMWare) is reproducable in a supported

environment (physical environment), oracle will search for a solution...

Is this the truth?

Yes, I can think of many reasons to virtualize everything, but when it comes to big systems and high performance I can also think of as many more not to. In this case you have to buy 2 beefy servers and 2 copies of ESX Enterprise when a single beefy server would do.

SMP performance is still not on par with physical gear. It sounds like the OP is being pushed to support this footprint because of perceived performance requirments, but wants to also take this on as his first virtualization project.

Granted, the project will probably pencil out if there is a chance to run multiple other VMs on the same new stack. If you could get 6 vms on the 2 server stack the project is probably break even if you buy 3rd party memory for the hosts.

I think a lot of VMware. I just know it's not the only hammer in the toolbox.
