Microsoft responds to VMware performance benchmark report
VMware recently commissioned a study comparing performance between vSphere 5 and Hyper-V 2.0 SP1. The study involves virtual machines running a database simulation workload with 24 VMs (without memory overcommit) and 30 VMs (with memory overcommit). The results show that VMware vSphere outperforms Hyper-V in each scenario. The original performance report can be found here…
Storage DRS of Exchange 2010 Workloads
On September 15th, VMware released a new whitepaper entitled “Microsoft Exchange Server 2010 Performance on vSphere 5.” If you are interested in virtualizing Exchange 2010 (or really any mission critical application) I’d recommend giving it a read. One of the interesting things they’ve done in this test aside from scale up/scale out testing is to…
Isolated clusters for mission critical applications?
I’ve seen a theme at several customers who are virtualizing mission critical applications on vSphere: The isolated vSphere cluster used just for that application. I’ve seen organizations do this many times when virtualizing Exchange 2010, often dedicating two or three vSphere hosts just for Exchange and related components (domain controller, virtual load balancer, etc). There…
Playing with VMware Zimbra for Android
I’m not much of an app user to be honest, and I’m definitely not an app reviewer. I use an HTC Evo (which runs Android) and don’t have that many applications installed. By far the most important application my phone is the email client connecting to my corporate Exchange server. When I saw that VMware…
My Next Step….
Whenever any virtualization blogger makes a post with a title like this it’s usually obvious what the post is about. So you can probably figure out where I’m going with this. I’ve decided that it’s time to take on a new challenge in my career. To that end I’ve accepted an Advisory Consultant position with…

Fix Partition Alignment with VMware Converter 5.0 (Beta)
I saw the news today that VMware released a public beta of VMware vCenter Converter 5.0 and was interested in the new features. Having used VMware’s P2V tools since ESX 2.x and the days of the P2V Assistant I’m always interested to see how the product matures to make the P2V process easier. Probably the…
Clearing up confusion regarding HA/vMotion support for Exchange 2010
As I discussed last week, Microsoft has updated their guidance and support regarding hypervisor high availability and live migration technologies with Exchange 2010. This is welcome news for anyone looking to virtualize Exchange 2010 on vSphere, as it now allows you to take advantage of vMotion and HA on all Exchange servers, even those in…
vSphere and Exchange admins can live in harmony – Microsoft finally supports HA and vMotion
This Saturday, Microsoft published a new white paper entitled “Best Practices for Virtualizing Exchange Server 2010 with Windows Server 2008 R2 Hyper V” that provides a lot of great info that is applicable to VMware as well. One of the most important things in this entire document is a change in policy regarding supporting virtualized…
VMware conducting vCenter high availability survey
This week on VMware’s Uptime Blog I noticed a new post asking for customer feedback about vCenter high availability requirements. To that end, VMware has posted a survey for customers to fill out to get more information. To be clear, the survey addresses high availability of the vCenter server itself and does not relate to…
