HPUX server consolidation.

Hi All,

We are using HPUX 10.20, 11.00 and 11.11.

We have configured HP Integrity Virtual Machines in new 6600 server.

Now we would like to create virtual machines in that and like to move current physical server in to that.

I have some questions?

1) What are the main things, we have to concentrate before moving the physical server to virtual server.

2)what are the criticality that we will face when moving physical server to virtual server.

Re: HPUX server consolidation.

I think you're going to study the software version requirements. If I recall correctly, you will not be able to support multiple version of HP-UX on your virtual machines, so you're going to have a huge migration from your current environment to the new releases.

Re: HPUX server consolidation.

Shalom,

1) Having enough physical memory and boot devices to configure these systems. I would want a boot device, some disk space, and 2-4 GB of RAM for each HPVM system I set up. More if its a heavy duty system doing a lot of work.

The rx6600 has a large memory capacity and a large number of SAS disks. It can do a fairly large amount of work. I would if you really plan a big consolidation on having as many CPU's as the system can handle.

2) Memory, CPU availability and perhaps disk I/O. I do not recommend booting systems of a SAN. If you use a SAN I'd want a fairly large number of HBA's in the system to avoid bottlenecks on disk I/O.

Re: HPUX server consolidation.

You can use HP virtual machines, but keep in mind:

OS minimum version is 11.23!

impossible to run 10.20, 11.00 or 11.11!

Hope this helps!

Torsten.

Pete: "you will not be able to support multiple version of HP-UX on your virtual machines"

Not 100% correct, you can mix 11.23 and 11.31; additionally you can run linux and windows in virtual machines.

Hope this helps!

Re: HPUX server consolidation.

I think SAS is good for the root disks for guest servers as performance is not that critical for root file system.

Re: HPUX server consolidation.

I thought it was fairly obvious that there would be a migration from 10.20 11.00 and 11.11 to 11.23

Maybe not.

All applications will have to be migrated and in some cases data will have to be converted.

Re: HPUX server consolidation.

Long story in short, You will have to do a detailed capacity planning for the current system and asses their requirements. Once accessed co-ordinate with you apps and DB team to forcast the furture resource utilizations. Once you have those look for your 6600 and see if that can server with enough resources. Also consider interdependies and criticalities of each server as your base machine will be a single point of failure(depends on your hardware and power redundancies).

Re: HPUX server consolidation.

Thanks, Torsten! I had a nagging doubt that I might be mixing VPars truisms in where they didn't belong.

But there are going to be version issues and much migration work, either way.
