Comparing Isolation in Hardware and OS Virtualization

Jan 15, 2007 17:06

In our recent discussions with customers and analysts, the question of isolation has come up again. The reason is that whenever an article in the press needs a one-sentence explanation of OS virtualization it is something like ’OS virtualization provides better density and performance but cannot run different operating systems simultaneously and ( Read more... )

100 VEs on a single machine anonymous March 27 2007, 01:31:36 UTC

A 100 VEs on a single machine does sound like the product scales well. What type of machine would you say will support this number of VEs. Can you give out some model #s, processor speeds, cores, amount of RAM?

I could give you some generic numbers, but if you could provide me with a bit more specifics about the workload, I would be able to give you a more precise estimate.

I'd like to know the VE scalability for

1) Running a (say IIS) webserver with on an average 100 connections in 10 mins. How many maximum such VEs can I run concurrently and what type of hardware is required.

2) A terminal services VE that supports 30 task workers (each user "TS desktop" session launcing a Microsoft Office application, Yahoo Messenger IM, Internet Explorer browser). How many such terminal services VE can I run maximum concurrently and what type of hardware is required.

3) Any general guidelines on "webserver" VEs/processor core? Will the # of VEs supported scale linearly as the # of cores increase.

4) Any general guideline on "webserver" VEs minimum RAM requirements?

Thanks

Hi again
for the typical IIS workloads - it is a typical real-life workload taken from one of our volume customer - I have the following numbers for you
4GB machine - 50 VEs
8GB machine - 120 VEs
16GB machine - 210 VEs
tests were run on Windows 2003 x64 Standard Edition server.
number of CPUs is typically not a limiting factor, so depending on the workload. you might go anywhere from a single-CPU, single-core to dual-CPU, dual-core machine.
I don't think I have any data, from which we could extrapolate how many 30-TS-user VEs can be running at the same time. I'll check for it, though.

Thanks!
