  • Guest Post: Virtual Eggs in One Virtualization Basket?

    Hi, my name is Dave Demlow and I am the Chief Technology Officer at Double-Take Software. Double-Take Software has been a leading provider of data replication and failover technologies for Microsoft Windows Server and applications going all the way back to Windows NT 3.51. So like many of you, we’ve seen many changes in the role that Windows Servers play in the enterprise and in the increased requirements for the availability and protection of Windows-based workloads. Hyper-V will accelerate those changes but at the same time make it much easier and more cost effective than ever to provide those higher levels of availability to an even broader range of workloads. As Jeff Woolsey highlighted so well in his post on Hyper-V Quick Migration, “Virtualization actually creates a major problem: single point of failure.” And if the problem with that isn’t crystal clear,” If that virtualization server goes down and I don’t have a HA solution in place, I will lose my job.” The hypervisor is only one of many possible points of failure to be concerned with. If the shared storage in a Hyper-V cluster is unavailable due to a site failure, power failure or corruption, ALL of your workloads that rely on that storage or site will also be down. Fortunately, Windows Server 2008 provides two enabling technologies, Hyper-V and Failover Clustering, that when used with 3rd party products such as our GeoCluster for Windows or Double-Take for Windows software can create clusters of Hyper-V servers that offer redundancy through replicated storage. Optionally, these can be geographically dispersed to maintain availability of virtualized workloads even when entire sites or datacenters are inoperative also providing for off-site disaster recovery. These are sometimes referred to as “multi-site” or “stretched” clusters and our customers often simply refer to them by our brand name GeoCluster.
  • Beta of standalone hypervisor: Hyper-V Server 2008 R2

    Hello fellow virtualization fans, Bryon here again. With all the excitement around the beta release of Windows Server 2008 R2, it’s important to call attention to another important beta release: Microsoft Hyper-V Server 2008 R2! To ensure there is no confusion, let me be clear that I’m talking about Microsoft Hyper-V Server 2008 R2. Not Hyper-V the feature of Windows Server 2008 R2. Alessandro’s post did a good job showing the differences. Microsoft Hyper-V Server 2008 R2 is the next generation of the standalone hypervisor based product.
  • WinServer 2K8 Hyper-V is alive

    Fellow Virtualization Fans, Bryon Surace here. I’m a senior program manager on the server virtualization team. Last week Steve Ballmer officially announced the public availability of Windows Server 2008 R2 Beta! So did my friends over at the Windows...
  • DPM for data backup/recovery of virtualized apps and environments

    We want to congratulate the Microsoft Storage Solutions team for releasing Service Pack 1 for System Center Data Protection Manager 2007. SP1 for DPM 2007 brings some great new capabilities for protecting Hyper-V environments (as well as ESX Server). Most notably, of course, is the ability to protect guests within Hyper-V environments, often without downtime (for those guests running a Windows operating system that supports VSS). Also new for DPM with SP1 is the ability to run the DPM server on the Hyper-V host itself, so that the DPM server can protect the guests from the host viewpoint, within the same physical server - to disk, to tape and even to the cloud. And unlike other (shall-not-be-named) virtualization platforms’ backup mechanisms, DPM does not require a SAN and does not require 3rd party backup software or add-ons. It’s an all Microsoft backup and recovery solution for Microsoft’s virtualization platform. For more details on the SP1 release for DPM 2007, check out: · Bala’s executive viewpoint on DPM 2007 sp1
