One very active hospital CIO...good reading at this blog for anyone in the Health IT business...he's right on the money with not only saving software and hardware costs with Virtualization, but also keep the power use down for the environment. Don't know what this is all about? Intel builds this technology right in to today's processors and it's there for the taking with Dual and Quad Core technology processor platforms...retiring 20 physical consoles is a huge benefit all the way around...and did I mention security here...big plus too. More about Intel and blade servers here. With Windows Server 2008 due out in February with the virtuals "burned in" to the operating system, this is something to really explore all the way around and have the potential to gain more bandwidth on the LAN and WAN while you are at it...BD
Server Consolidation - Many of our computer servers in the data center support only one application. This is often requested by the application vendor. Virtualization software such as VMWare is now available that allows multiple instances of a computer operating system to exist on the same server. Each instance can be configured in a way that assures needed server resources (memory, CPU, etc) are available. We have retired over 20 servers in the past year through this technique.
Life as a Healthcare CIO: Kill a Watt!
We have also begun the extensive use of VMware, Xen and other Virtualization techniques. This means that we can host farms of Intel/AMD blades running Windows or Linux, deploying CPU capacity on demand without adding new hardware. We're connecting two geographically distant data centers together using low cost dark fiber and building "clouds" of server capacity. We create, move and load balance virtual servers without interrupting applications.
