physical machine to Vmware conversion.

Hi,

We are running our Production server in physical machines we would like to change the physical server to Vmware, please let us know the below details.


We are running on windows 2012 server os and database- sybase 16.0.01.01

  1. After converting from Physical to VM is there any challenges.
  2. What are all the process involved on this.

Anyone has come across this scenario.

Thank you

Naveen

    Hi Naveen,

    I rearranged the tags on your question a bit. I believe this should go under Virtualization, but if I'm wrong, I'm sure the moderators for that tag will help it further along.

    I can't speak to the specifics of how this migration is done, but it's definitely possible. We run a mix of physical and VMware instances for our SAP systems in our shop, and the VMware instances work just fine. There are Notes and various guides available online that discuss the best way to configure VMware for SAP; you should be able to find them with a little searching.

    As for the migration (or virtualization) process itself, I believe this is more of a VMware process than an SAP process. In our case, this has always been handled by our data center operations (network/server operations) staff, not by the SAP Basis team. All we did was specify to them how much CPU and memory needed to be allocated.

    When we first brought VMware into our environment, a number of years ago, we had some growing pains with it, and at that time I was not prepared to commit anything other than sandbox instances to it. Since then, however, our data center staff have become experts at managing it, and the environment has stabilized, so today I have no reservations. Our largest production instances are still physical hardware, but I doubt I'll ever buy dedicated hardware for SAP again -- when it's time for the next hardware refresh, I'll look into migrating into VMware, if we haven't gone cloud by then. VMware has some definite advantages for management of the server host. For instance, it's much easier to expand the available memory on the fly (no downtime!), and since even the C: drive is on the SAN, that can be expanded while online if the need arises. Failover capabilities are also handled by VMware, so you don't have to worry as much about special OS configurations for this, so it's more fault-tolerant.

    Cheers,
    Matt
