Igloo Products Corporation, the world's #1 cooler manufacturer, has migrated its legacy IBM mainframe IT infrastructure to Oracle's Sun SPARC servers and Oracle software in a move that is anticipated to deliver 169% ROI in three years and a break-even point in the first year. Igloo has consolidated its operations on two Sun SPARC Enterprise T-Series servers -- the Sun SPARC Enterprise T5140 and T5240 -- in a virtualized system employing Oracle Solaris Containers. Igloo has determined that it can reduce its former monthly hosting fees by half now that it uses 66% fewer servers and 83% fewer CPUs.

The once Sun Logical Domains is now the Oracle VM Server for SPARC. Leveraging the built-in SPARC hypervisor to subdivide supported platforms' resources (CPUs, memory, network, and storage) by creating partitions called logical (or virtual) domains, the Oracle VM Server allows for the creation of up to 128 virtual servers on one system to take advantage of the massive thread scale offered by the Sun SPARC Enterprise Systems with Chip Multithreading (CMT) technology. Honglin Su writing for Oracle's Virtualization Blog recapitulates the solution's features, architecture, and systems support.
