Data Center Virtualization

Data Center Virtualization covers virtualizing servers, networks, and storage delivering server consolidation, CAPEX savings, IT agility, and improved management. Major areas of focus include the tradeoffs between various virtualization platforms (VMware vSphere, Microsoft Hyper-V and Red Hat KVM), the evolution of hypervisors into data center management platforms, (Read More)

VMware’s Software Defined Data Center strategy, and how the SDDC is spurring innovation in storage, networking and server hardware. Covered vendors indlude VMware, Microsoft, Red Hat, CloudPhysics, Hotlink, Tintri, and VMTurbo.

IT Transformation: Show Back

CloudComputingThe last part of our IT transformation series is on show-back. The final—some say the first—component of using any cloud for Infrastructure as a Service (IaaS) is cost. We plan to use a cloud to save on costs, but we have to be able to prove we will save money. Unfortunately, with all the approaches to IT transformation—top-down, migration, no changes to management—the truth is that excessive cloud use could turn into massive costs. Those costs, if not handled properly, will end up hamstringing any IT transformation after it happens. The answer is show-back. Continue reading IT Transformation: Show Back

Scale-Out Is a Benefit to HyperConverged

DataCenterVirtualizationI recently upgraded my nodes from 96 GB of memory to 256 GB of memory, and someone on Twitter stated the following:

@Texiwill thought the trend today is scale out not scale up? #cloud

The implication was that you never upgrade your hardware: you buy new or you enter the cloud. Granted, both options are beneficial. However, buying new and adding to your environment may not be necessary, and you most likely have already entered the cloud with the use of SaaS applications and perhaps some IaaS. The question still remains: upgrade, enhance existing hardware, or buy net new somewhere? When should you do any of these? Or should you at all?

Business Performance and Agility: Are We Measuring the Correct Metrics?

Speed.In the EUC world, it is euphemistically stated that the only performance metric that counts is user experience. What this means is that from a business and management perspective, it does not matter a single jot how much green is showing in your NOC view; if your users are not happy, you have a problem. Is this the case in the server world? Continue reading Business Performance and Agility: Are We Measuring the Correct Metrics?

Choices We Have Plenty: Your Guide to Virtual Switches

DataCenterVirtualizationI was tinkering around with XenServer the other day. I know I can hear you saying “is that a thing?” Well, it is, but this is not what I am going to talk about today. Time for a tangent shift. I thought I would have a look for a third-party switch for XenServer, but it seems that XenServer is a third-rate citizen in this space, as there is no Cisco Nexus 1kV available for XenServer, even though Cisco previewed it at Citrix Synergy Barcelona in 2012.

Whatever Happened to Mobile Virtualization?

DataCenterVirtualizationWhatever happened to mobile virtualization? Just a couple years ago, there seemed to be a ton of hype about mobile virtualization. The goal was to be able to run multiple isolated virtual instances on a single physical device. I remember walking the expo floor during the VMworld conference that year and seeing all the demo phones on display; I also saw a demo of the technology during one of the keynote presentations. Then, focus seemed to move over to network virtualization.
