I’ve been in the IT business long enough that when someone mentions KVM I flash back to days of running serial cables from servers to control boxes and pushing hardware switches to change console control from one server to another. I even remember how big a deal it was when vendors started to use UTP to connect their devices to servers rather than those clunky serial cables, and the wonder of wonders when in-band KVM started to become available and cable concerns became a thing of the past.
With the advent of RDP technologies there is a tendency to think of KVM as an outdated technology, but the reality is that it has simply evolved into a new stage in its lifecycle. The new Intel Virtual Gateway (IVG) is a good example of the direction that KVM has gone. Rather than a discrete product, the IVG is an SDK designed to allow DCIM software OEMs to integrate KVM capabilities into their infrastructure management solutions.
With the IVG and supported systems the administrator can control up to 50 systems simultaneously, via either in-band or out-of-band management, integrated as part of the OEMs DCIM solution. The control is in real-time, with a single pane of glass view and can mix OOB and IB management in the same view of managed resources.
The SDK makes it easy for the DCIM vendors to add these capabilities to their products; Intel also includes an executable installer and packaged binaries for re-distribution by the OEMs which reduces the amount of work that needs to be done to integrate IVG into their existing products.
The KVM capabilities are supported across multiple platforms simultaneously; any mix of the supported server hardware can be controlled from any supported console. Operating system support is currently limited to Windows Server 2008SP2 and newer, SUSE Linux Enterprise Server 11 SP1 and Red Hat Enterprise Linux 6.2/6.3 though the roadmap plans include further OS support and additional server hardware OEMS beyond the half-dozen top server vendors announced at release.
