Need you sugguestion to shift current physical server to VM. (Machine count is >21000)
will it be good to shift Safeboot server and DB to VM server with considering above scenario ? (as management wants to move all physical servers to VM environment )..
Your sugguestions will help me to take decision
intitally I thought there would not be a problem.. but found something..
says.. its not good for big database...
your sugguestions will be really appreciated
Thanks in advance
In my experience VMWare suffers performance problems with DBS of that size unless you properly configuration it with tier 1 San storage etc. It will work fine, but if it's slow, you'll need to dedicate more resources to it.
The storage fabric is the most important thing, SAN never seems to be as fast as DAS.
So by all means migrate, just have a plan B to roll back if needs be. If you virtualize and things slow down, thats really your best option.
This is just my opinion and experience, but I think VM is not a realistic solution for EEM unless you can have enough resources dedicated to your EEM server environment. However, dedicating enough resources tends to be counter to how I have seen VM used. We tried it initially supporting about 5000 clients and the response time was poor. The point of VM in our environment is to try and consume as close to 100% of the hardware resources as possible to save on resources. To get close to that 100% usage, the ESX server tends to be over allocated. That caused us to have performance issues when any of the other VM client systems started to spike in usage. Heavy disk usage was especially noticeable. We ran on a VM from September 2010 to February 2011. In late February, our EEM server was migrated from a VM based environment to a physical environment. The new physical environment is much more responsive.
Hi Simon and bselzer
many thanks for your valuable suguestions.
