System x3550 M4 server

High-performance server subsystems

The System x3550 M4 expands the new server line by adding a higher level of processor power. This high-throughput, two-way multicore network server offers excellent performance and scalability when you add memory and a second processor. It incorporates powerful Xeon processors with up to 20 MB L3 cache. The advanced transfer L3 cache is integrated onto the processor and runs at the same clock speed. The advanced transfer cache is a result of a “backside bus” 256 bits wide. It features a quad-wide cache line that can transfer four 64-bit cache line segments at one time to deliver full-speed capability. The cache is eight-way set associative.

Two Intel Xeon processor connectors are standard on the system board to support installation of a second processor, up to 20M cache, and up to two 8.0 GT/s QuickPath Interconnects (QPIs) with new Hyper Threading and Intel™ Turbo Boost Technology 2.0. High-speed PC3 DDR3 Advanced Memory Feature DIMMs run at up to 1600 MHz DRAM clock speed and offer maximum 12800 MBps bandwidth, processor-to-memory subsystem performance. The x3550 M4 server uses the Intel E5-2600 processor with Chipkill technology to maximize throughput from processors, to memory, to the 32-bit and 64-bit PCI buses.

Additional features
  • Up to 16-core processing achieved with a second processor of equal speed and processor type.
  • System board containing 24 DIMM (UDIMM/RDIMM/LRDIMM/HCDIMM) connectors supporting 4 GB, 8 GB, and 16 GB DDR3 PC3-12800 SDRAM ECC RDIMMs with:
    • DDR3 memory for improved performance
    • Up to 384 GB of system memory using 16 GB optional DIMMs or up to 768 GB of memory with 32 GB LRDIMMs
    • Support for two DIMMs per channel at 1600 MHz with supported 1600 MHz RDIMMs
  • Up to two PCIe 3.0 slots. Clients ordering a single-processor model can select:
    • Two PCIe 3.0 slots: one PCIe 3.0 x16 low profile and one x8 half length, full height (standard models).
    • An optional PCI-x half length, full height slot to replace one x8 half length, full height slot. With 2nd CPU population, clients can optionally buy one x16 half length, full height PCIe 3.0 slot to replace one x8 half length, full height slot.
  • On standard models, four 2.5-inch bays or three 3.5-inch bays to support optional SAS/SATA HDDs and one bay to support an optical drive for 2.5-inch models.
  • Intel i350-AM4 Quad-port Gbit Ethernet on board and embedded 10 GbE Dual-port options (on a reserved connector). The embedded card supports Emulex, QLogic, and Mellanox with different protocols like 10Gb SFP+ or 10BASE-T or InfiniBand.
  • Compliant with 80 PLUS Platinum and ENERGY STAR (model dependent).

The System x3550 M4 offers solid system throughput from processor, to memory, to bus, to disk-intensive I/O. These features, combined with multicore capability, make the x3550 M4 server an excellent choice for a stand-alone or clustered general-business application, file, and print server.
