With VMworld around the corner, it is interesting to note the new and old players within the Virtualization Backup space. The virtualization backup space often includes:
- VM Backup
- VM Replication
- Continuous Data Protection (CDP)
- Storage Hardware Replication
Virtualization Backup includes pretty much anything that will maintain your VMs while allowing your data to be placed elsewhere for later retrieval; such a place could even be the cloud. In this article we will avoid Storage Hardware Replication and discuss only backup software. Continue reading Virtualization Backup Round-up
One announcement that is unlikely to be made at VMworld in 2010 is the release of VMware’s Client Hypervisor. While VMware may have got accustomed to dominating the world of server virtualization, its attempts to become the de-facto virtualization vendor on the desktop haven’t gone quite as well. Despite it being nearly two years since announcing its “vClient initiative“, VMware has yet to announce a delivery date for the proposed client side hypervisor component. Citrix, on the other hand, is proudly touting XenClient. Other vendors, such as VirtualComputer are actively promoting their products.
Its likely Citrix will have beaten VMware to delivering a Client Hypervisor. While XenClient is currently a Release Candidate version, Citrix announced that the v1.0 will be released with XenDesktop 4 Feature Pack 2 in September 2010.
Is the lack of Client Hypervisor (CHv) a problem for VMware in delivering a complete desktop solution to customers? Indeed, is the CHv technology viable for business use now? And when (and if) it is a viable technology, where should a CHv be considered in your desktop strategy? What could a Client Hypervisor be used for?

When I first started with virtualization, the only option you had at the time was single core processors in the hosts. Scale up or scale out was the hot debatable topic when designing your infrastructure. On one side of the coin the idea was to scale up in that it was best to get a few of the biggest servers you could find and load them up with as much memory and processors that you could fit in the box. The end result were some very expensive servers able to run a lot of virtual machines for its time. The other side of the coin presented the idea that it was better to scale out with more, smaller servers to make up the cluster. I have worked in both type of environments and attitudes over the years and as for me, personally, I aligned myself with the scale out philosophy. The simple reason for aligning with the scale out group was host failure. When you have sixty to eighty virtual machines per host and lose that host it was really a lot of eggs in one basket and took some time to recover. When you have more, smaller servers, then the shock of losing a host was not as severe because there were not as many virtual machines running on single host and it would take less time to recover. This was during the time before vCenter, vMotion, HA and DRS when it was just you and the VMware ESX hosts. Continue reading Coming Full Circle on Scale Out vs. Scale Up
When discussing Virtualization Performance Management, we separate the vendors that focus upon this area in to three groups:
- Resource and Availability Management – this group of vendors focuses upon collecting the resource utilization metrics that are made available by the virtualization platform vendors for the purposes of capacity planning, capacity management, and ensuring the overall availability of the environment. Leaders in this category include Vizioncore (vFoglight), Veeam (Veeam Monitor), VMware (Hyperic), Hyper9, Netuitive, and Zenoss.

We recently annoyed Peder Ulander of Cloud.com by suggesting when Cloud.com joined OpenStack it was a Turkey waiting for Thanksgiving. It wasn’t personal, but we do understand that being compared to a fat bird with a big neck can cause offense. To calm things down we spoke to Peder, and we thought Virtualization Practice readers might be interested in the conversation. Continue reading Why Cloud.com is NOT a drowning turkey
VMworld is clearly a Very Big Virtualization Conference – possibly the largest. Yet, does it cover all virtualization topics? If you’re from a Presentation Virtualization (PV) background (although maybe you know it as Terminal Services (TS); possibly even a Microsoft Remote Desktop Services (RDS); heck lets go on an old school ‘server based computing’ perspective):
‘what could VMworld do for me?’
The answer is:
“Quite a lot.”
I know: you’re shocked: I was bemused too. From a PV perspective there are a number of vendors worth your while to to go and see. I’m not going: wish I was now.
