Memory options

The IBM System x3650 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. The following rules apply when selecting the memory configuration:

• Server supports UDIMMs, RDIMMs, HyperCloud DIMMs (also known as HCDIMMs), and LRDIMMs.
• Mixing different types of memory (UDIMMs, RDIMMs, HyperCloud DIMMs, and LRDIMMs) is not supported.
• Mixing 1.5 V and 1.35 V DIMMs in the same server is supported; in such a case, all DIMMs operate at 1.5 V.
• Maximum number of ranks 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 the server depends on the number of CPUs, DIMM type, rank, and operating voltage, as shown in the "Max. qty supported" row in Table 5.
• All DIMMs in the server operate at the same speed, which is determined as the lowest value of:
  • Memory speed that is supported by the specific CPU.
  • Lowest of maximum operating speeds for selected memory configuration that depends on rated speed, operating voltage, and quantity of DIMMs per channel, as shown under "Max. operating speed" section in Table 5.

The following table (Parts 1 and 2) 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.

Table 5. Maximum memory speeds (Part 1: UDIMMs and RDIMMs)

Table 5. Maximum memory speeds (Part 2: HyperCloud DIMMs and LRDIMMs)

* Maximum quantity supported is shown for two processors installed. When one processor is installed, the maximum quantity supported is a half of the quantity that is shown. Shaded cells indicate when all DIMM sockets can be occupied.
** NS = Not Supported

The following memory protection technologies are supported:

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

If memory mirroring is used, DIMMs must be installed in pairs (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 the memory options that are available for x3650 M4 server.

Remote management

The server contains IBM 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 IMM2 lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. Optionally, the IMM2 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 IBM 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 colors, 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.
