Double-Take Software

Robin Wauters from Virtualization.com cross-posted a good article a few weeks ago “VMware’s Biggest Threat isn’t Microsoft” written by Gregory Ness, which describes some of the challenges VMware faces being confined to hypervisor VLANS. This article brings up several good points though regarding the requirements of a dynamic infrastructure for not only the cloud but being able to perform these functions over existing networks. Many companies have promised a Dynamic Infrastructure over the years but have been limited to proprietary solutions tied to the specific hardware vendors. Unfortunately, VMware has kind have taken this same approach tying their “Site Recovery Manager” functionality to the specific appliance that is providing the disk based snapshots. This certainly doesn’t provide the VMotion like capabilities over a WAN and again limits itself to the hardware and only the virtualized hardware at that. Only have 30% of x86 servers have been virtualized so far, which is an incredible statistic, but there are still plenty of physical servers that in the mean time don’t qualify for this type of solution. Dynamic Infrastructure is going to be a software solution that is hardware independent and free from O/S, virtualization products as well as hardware vendors. This is truly the only way that the provisioning, management and transfer of systems over a WAN will be capable of being performed and creating a true dynamic infrastructure.
