Exchange 2010 on VMware vSphere

May 24, 2010 by danbrinkmann

Short article showing the impact of adding memory to the virtual machine running Exchange 2010 on top of vSphere.  As you will see there is quite an impact adding memory can have on the amount of disk I/O generated.  With the I/O numbers generated you certainly don’t need expensive EMC disk either!

The next link is to the first part of the series where they tested the impact of adding virtual cpu’s to the Exchange 2010 server(s).

What is interesting in both cases is the amount of cpu and disk for 8000 users in both of these test is EASILY within the capabilities of VMware vSphere….so virtualize already!

May 18, 2010 by danbrinkmann

Local storage?  Yeah i know crazy!  But in some Desktop Virtualization environments maybe it’s good enough?   Hmmm….

VMware vCenter Webservices service chewing up all your memory?

May 18, 2010 by danbrinkmann

Oh yeah… we all have testbeds and we all love to waste the extra memory we have in them…uhm…wait, no I don’t!

I’m going to be applying this tonight to my own vCenter lab environment…that poor PC just dies with all the memory/disk swapping it is doing.

Google apps is out, Microsoft is in

May 18, 2010 by danbrinkmann

OK so it’s also written by Microsoft but it is interesting to see some of Google’s vocal supporters now making the move to Microsoft.

Enterprise SSD market to soar

May 18, 2010 by danbrinkmann

We’ve definitely been noticing an uptick in SSD interest and I feel this is one of those transformational technologies…you know, the kind that are like shaking the etch-a-sketch.  SSD not only is the cheapest $ per IO it also offers DRAMATICALLY faster response time.  Imagine taking your “fast” 15,000 RPM SAS disk with a 3-5ms (or more in most cases) response time and knocking that down to something in the MICRO-second level…access that disk a few million times a day…yeah…that’s a big difference.

If you want to dive deeper on this topic email me dan.brinkmann@lewan.com , this is a transformational technology!
