† Processor detail: Processor quantity and model, cores, core speed, L3 cache, memory speed, TDP.
§ For models A3x and B3x, the standard DIMM is rated at 1600 MHz, but operates at up to 1333 MHz to match the processor memory speed. Actual memory speed maximums depend on several factors, as described in "Memory options".

The following table lists the Express models.

§ The standard DIMM is rated at 1600 MHz (models E6G, EGU, ELC, EOC, ESC, ETC, FFM, and K4G) or 1866 MHz (model CCU), but operates at up to 1333 MHz to match the processor memory speed. For models EFG and CEU, the standard DIMM is rated at 1866 MHz, but operates at up to 1600 MHz to match the processor memory speed. Actual memory speed maximums depend on several factors, as described in "Memory options".

The x3550 M4 supports the processor options listed in the following table. The server supports up to two processors. This table shows which server models have each processor standard. If there is no corresponding where used model for a particular processor, then this processor is only available through CTO. The part numbers include two system fans.

* The first feature code is for the first processor; the second feature code is for the second processor

System x DDR3 memory is compatibility tested and tuned for optimal System x performance and throughput. System x memory specifications are integrated into the light path diagnostics for immediate system performance feedback and optimum system uptime. From a service and support standpoint, System x memory automatically assumes the system's warranty, and Lenovo provides service and support worldwide.

The System x3550 M4 supports DDR3 memory. The server supports up to 12 DIMMs when one processor is installed, and up to 24 DIMMs when two processors are installed. Each processor has four memory channels, and there are three DIMMs per channel.

• Server supports RDIMMs, and LRDIMMs.
• Mixing different types of memory (RDIMMs and LRDIMMs) is not supported.
• Mixing 1.5 V and 1.35 V DIMMs in the same server is supported; in such cases, all DIMMs operate at 1.5 V.
• The maximum number of ranks supported per one channel is eight (with the exception of Load Reduced DIMMs, where more than eight ranks are supported because one quad-rank LRDIMM provides the same electrical load on a memory bus as a single-rank RDIMM).
• The maximum quantity of DIMMs that can be installed in server depends on number of CPUs, DIMM type, rank, and operating voltage as shown in the "Maximum quantity" row in the following table.
• All DIMMs in all CPU memory channels operate at the same speed, which is determined as the lowest value of:
  • The memory speed supported by the specific CPU.
  • The lowest of maximum operating speeds for the selected memory configuration that depends on rated speed, operating voltage, and quantity of DIMMs per channel, as shown under "Maximum operating speed" section in the following table.

The following table shows the characteristics of the supported DIMMs. Tables cells highlighted with a gray background indicate when the combination of DIMM voltage and the number of DIMMs per channel still allows the DIMMs to operate at a rated speed.

* The maximum quantity that is supported is shown for two processors installed.

The following memory protection technologies are supported:

• ECC
• Chipkill (for x4-based memory DIMMs)
• Memory mirroring
• Memory rank sparing

If memory mirroring is used, then DIMMs must be installed in pairs (a minimum of one pair per each CPU), and both DIMMs in a pair must be identical in type and size.

If memory rank sparing is used, then a minimum of one quad-rank DIMM or two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need being identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs installed.

The following table lists memory options available for the x3550 M4 server.

This will ensure that the right power supply is chosen for optimal performance.

The server supports VMware ESXi installed on a USB memory key. The key is installed in a USB socket inside the server. The following table lists the virtualization options.

The server contains Integrated Management Module II (IMM2), which provides advanced service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. Optionally, the IMM also provides a virtual presence capability for remote server management capabilities.

The IMM provides remote server management through industry-standard interfaces:

• Intelligent Platform Management Interface (IPMI) Version 2.0
• Simple Network Management Protocol (SNMP) Version 3
• Common Information Model (CIM)
• Web browser

The optional Integrated Management Module Advanced Upgrade is required to enable the remote presence and blue-screen capture features. The remote presence feature provides the following functions:

• Remotely viewing video with graphics resolutions up to 1600x1200 at 75 Hz with up to 23 bits per pixel, regardless of the system state
• Remotely accessing the server using the keyboard and mouse from a remote client
• Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server
• Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the IMM restarts the server when the IMM detects an operating system hang condition. A system administrator can use the blue-screen capture to assist in determining the cause of the hang condition. The following table lists the remote management option.

All standard models ship with a pop-out light path diagnostics panel on the front of the server (See Figure 2). Configure-to-order (CTO) customers may elect to deselect this feature and instead have a basic light path diagnostics panel on the front of the server.
