You need to reduce the costs of doing business andimprove the service you deliver to your customers while lowering your overall risk. The dual-socket IBM® System x3550 M3 can reduce your costs with its new energy smart design. It canimprove service with reduced operational complexity and increased management functionality. Itwill lower your IT risk with the resiliency that comes from no single point of failure. And like allIBM servers, the x3550 M3 offers you the trust that comes from the IBM global reach, service andsupport.The x3550 M3 is a game-changing rack server that uses significantly less power than previousgenerations, with unified systems management tools, leadership reliability, availability, andserviceability features and broad systems flexibility, housed in a compact 1U mechanicalpackage.The x3550 M3 features Intel® Xeon® 5600 series 6-core and 4-core processors, with up to12MB of shared L3 cache, to provide you with the computing power you need to match yourbusiness needs and growth. The new line of Intel processors delivers unprecedented intelligentperformance with features like adaptive performance for applications and environments, TurboBoost Technology and Hyper-Threading Technology, and integrated power gates and automatedpower management.The x3550 M3 supports up to 18 DIMMs / 192GB of registered (RDIMM) 1333MHz DDR3memory (or up to 12 DIMMs / 48GB of unbuffered UDIMM memory) and provides Chipkill™ ECC(Error Checking and Correcting) protection—for high performance and reliability. For even higherlevels of availability, the x3550 M3 also offers memory mirroring. Up to 4 integrated high-speedGigabit Ethernet ports are available (offering TOE (TCP Offload Engine) support on Microsoft®Windows®), as are two high-performance adapter slots (PCIe x16). The x3650 M3 offers anoptional embedded hypervisor to manage your virtual workloads.The x3550 M3 offers a choice of up to supports up to 8 high-performance hot-swap HDDs with aninternal storage capacity of 8TB1 (2.5-inch hot-swap Serial-Attached SCSI (SAS) or Serial-Attached ATA (SATA) drives). Alternatively, up to 8 solid-state drives (SSDs) are alsoavailable to keep power low, improve resiliency, and offer up to 400GB of storage. The serverincludes a choice of several IBM ServeRAID® storage controllers that provide broad levels ofhardware-based RAID solutions. The ultradense 1U form factor allows businesses to increasetheir computing power and spread their workload without outgrowing their current data center. Upto 42 of these 1U servers can be installed in a single 42U rack, for a total of up to 84 processorsand 504 processor cores, offering tremendous deployment flexibility.Standard in the x3550 M3 is the Integrated Management Module (IMM) that enables the user tomanage and control the server easily—both locally and remotely. In conjunction with the IMM, thex3550 M3 comes with an altitude sensor (altimeter) that governs fan rotation based onaltitude, to help lower your energy consumption. The IMM offers a high level of manageability thatis designed to keep costs down and the system up—even when network usage increases. IBM’sinnovative pop-out/drop-down light path diagnostics panel enables quick servicing of thesystem if a problem develops. These advanced features help maximize network availability byincreasing uptime, as do hot simple-swap solid-state drives; hot-swap/redundant SAS orSATA HDDs, redundant ultra-efficient power supplies and fan modules; Active Memory™;integrated RAID; temperature-controlled fans with Calibrated Vectored Cooling™; IPMI 2.0support, including highly secure remote power control and Serial over LAN; as well as text-console redirect over LAN.1 1TB drives available in 2Q/2011.®
