The IBM xSeries 206m brings new features to entry-level servers that help lower overall IT costs and better accommodate growth. The x206m is highly expandable and provides unprecedented system availability. On select models, upgrade hard disk drives (HDDs) from low-cost, fixed Serial ATA (SATA) to Serial Attached SCSI (SAS), a new HDD technology that adds more performance and features. And even if a HDD or power supply fails, the x206m can stay up and running with features such as hot-swap SATA and SAS HDDs and redundant power supplies. New features such as DDR II memory and PCI-Express help extend the life of your system. Dual-core processor models provide higher performance for systems running multiple applications. Protect your data with IBM ServeRAID-8e, which provides RAID-0 or -1 delivering more features than standard server operating system based RAID.
