vSphere Upgrade no downtime

Hi,

This is the scenario:

10 ESXi 5.0 Hypervisors (free edition) with local storage

All of the VMs must be available 24/7

What I have to do:

Upgrade to a paid edition (std)

Upgrade to 5.1

Present a shared storage and move the VMs to it

Install a vCenter Server and add all of the hosts to it

Any suggestions for doing the "upgrade" part with no downtime for the VMs? Then I would just move them using storage vmotion available in vSphere 5.1 std.

I can think one way to do this but I would like to hear other members of VMware communities Smiley Happy

Thanks in advance!!!

In that case I would just use trial keys to do the installation/migration, in the end that is what you'd be doing when it was an entire new environment, I don't think VMware will be too difficult about it ... :smileyconfused:

24/7 will be tough because hardware failures will not allow for 100% uptime.  However, you can help getting closer to maybe 99.99% by implementing shared storage and HA.

To do this, you'll need to go to a paid subscription.  Below are some examples.

Well, that depends a little on your preferences I think ...

I'd go for installing the vCenter first, set up the entire cluster (add existing hosts, add the new shared storage, etc..), install update manager, make sure that you can either use a trial or available keys to (storage)vmotion the VM's to the other hosts and the shared storage, so they stay available, and finaly use update manager to update to the latest ESXi version.

All depends on what resources are available of course.

Hi Troy,

My english is not very good Smiley Happy So I will try to explain myself better. What I really would like to know if how could I upgrade the ESXi from free edition and 5.0 version to a std 5.1.

The edition it's easy because I will only have to introduce the license key and that would be all...but, how could I upgrade from 5.0 to 5.1 without having to power off or suspend the VMs in the local storage of the hosts?

Thanks again!

Hi spravtek!

Using trial keys was my first idea...you know temporary using a trial to have full Ent+ features in order to use Storage VMotion so I wouldn't have any VM running on that host and be free to power it down, etc.

The thing with this is that I would violate EULA terms using trials licenses in a production enviroment ( I think )

Thanks again!

you will need to install vCenter first, as noted above.  From there, you'll need shared storage for your Hosts.  Once you have shared storage you can storage vMotion your guests onto the shared storage.  This will get all the guests off local storage and onto shared, giving you the ability to rebuild/upgrade your hosts to 5.1.  Using vMotion you'll be able to do a rolling rebuild/upgrade with no downtime to your guests.

So, picking the right paid subscription would have to include Storage vMotion.  Standard will get you there.

Only in version 5.1...the host are with 5.0 free edition.

I could go like this

5.0 free edition > Insert the aquired std license keys > 5.0 Std

At that point, I wouldn't be able to use Storage VMotion as for 5.0 std was not an included feature.

Am I right?

I could be wrong, but I thought vSphere 5.0 Standard includes Storage vMotion ...

No storage vmotion for standard in Version 5...I wasn't 100% sure either so I found this

the FAQ section says otherwise. i tried the same question with vmware support who told me that one has to upgrade to 5.1 to use the new feature set and the new licensing. not sure why it says other wise in the above link.

Hi gsk308,

I can see the first page of that document where it says "vSphere 5" but reading it I found that:

For version 5.0 & 5.1, licensing restrictions for vRAM don't longer apply.

"

The new vSphere licensing model for both vSphere 5.0 and 5.1,
continues to be based on processor licenses. It eliminates the
restrictive physical entitlements of CPU cores and physical RAM
per server and has no limitation on the number of VMs or amount
of virtual memory (vRAM) on each licensed processor

"

By the other hand, the new functionalities in the version 5.1 of the hypervisor (that is the ESXi), are other thing, and to have that functionality you will have to upgrade to version 5.1 if using Standard edition. Same thing happened between 4.0 and 4.1 with other functionalities.

Hope this helps you! Smiley Happy
