PlateSpin's PowerRecon is a planning and monitoring application for organizations with a high number of servers and virtual host targets. On the surface, PowerRecon looks similar to traditional network monitoring/management applications that track application inventory, connectivity and network usage.

We like it, however, for what's underneath, which is a very useful server monitoring, planning and management tool (especially for VM hosts and instances) that can be coupled with PlateSpin's PowerConvert tool, which does a formidable job of moving server instances from physical to virtual and all the variations the virtual data center affords us today.

PowerRecon also has chargeback features that monitor and levy costs based on actual system uptime, CPU utilization, processor speed, memory used, network bandwidth used, and disk storage (space, speed and number of writes per second). By contrast, Virtugo's virtualSuite uses a patented, contrived metric for chargeback accounting purposes.

We were also impressed with PowerRecon's ability to work with a huge number of VM operating system candidates, including Windows NT 4 and XP through current Windows Server products (support for XP and Win 2003 Enterprise Server were tested and affirmed), most modern versions of Red Hat and SUSE Linux (Red Hat Enterprise 5 was tested) and Sun's Solaris 7 (Sparc) and Solaris versions 8-10 (Sparc and Intel/AMD). VM hosts can be running VMware ESX (tested), Citrix Systems' XenServer Enterprise Edition, Virtual Iron and/or Microsoft's Virtual Server 2005.

PowerRecon and associated daemon modules run as a Windows service application. Once installed, PowerRecon uses a Windows Explorer-like user interface called Data Center Explorer that performs a network discovery and maintains an inventory of hosts. Credentials are then supplied by the administrator for server hosts that need to be internally inventoried or further monitored. A handy list of credentials are provided but placing so many crucial passwords in a single place, even though they are protected by files and database access permissions, made us nervous.

The results of the inventory process were shown in a tabbed user interface containing descriptions of host or VM instance characteristics -- such as processors, general information, disk drive information, network adapters, applications, operating system services/daemons, and any other user-defined fields. Power dissipation is also tracked.
