System x3550 M3 - related options
The System x3550 M3 server features an Intel Xeon multicore processor that supports internal processing speeds of up to 3.60 GHz, and processing operations to memory up to 1333 MHz. They contain integrated, full-speed 4 MB, 8 MB, or 12 MB ECC L3 cache.

High-performance server subsystems
These servers are high-throughput, network servers with excellent scalability when you add memory and a second processor.

Two Intel Xeon connectors are standard on the system board to support installation of a second processor. High-speed DDR3 SDRAM Registered DIMM memory is optimized for 800 MHz, 1066 MHz, or 1333 MHz processor-to-memory subsystem performance.

Expandability and growth
The System x3550 M3 server contains high levels of function and storage capacity for a 1U, 19-inch rack-drawer package. It supports customer installation of adapters, processors, memory, and HDD options. Functions such as SVGA video, SAS, and two Gigabit Ethernet controllers are integrated on the system board.

Integrated Management Module (IMM)
The System x3550 M3 includes an Integrated Management Module that provides industry-standard Intelligent Platform Management Interface (IPMI) 2.0-compliant systems management. The IMM comes standard, and shares one of the two on-board Ethernet ports for access. The IMM can be accessed via software that is compatible with IPMI 2.0 .
