Refer to the Standards specifications section for information about the standard features of the server.

The x3750 M4 supports the processor options listed in the following table. The server supports up to four processors. Two processors are installed in sockets on the system board. Processors 3 and 4 are installed on the processor and memory expansion tray. Most models (with the exception of A2x, as listed in Table 2) have the expansion tray installed as standard. For model A2x, order part number 88Y7365 for the processor and memory expansion tray.

The following processor quantities are supported:

• One processor, installed in socket 1
• Two processors, installed in sockets 1 and 2
• Four processors, installed in all four sockets

The following table also shows which server models have each processor standard. If there is no corresponding where-used model for a particular processor, this processor is only available through CTO.

Table 3. Processor options

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

The System x3750 M4 supports DDR3 memory. The server supports up to 48 DIMMs when four processors are installed, with 12 DIMMs for each processor. 24 DIMM sockets (for processors 1 and 2) are located on the system board. The remaining DIMM sockets (for processors 3 and 4) are located on the processor and memory expansion tray. Each processor has four memory channels, and there are three DIMMs per channel.

The x3750 M4 memory system has been carefully tuned so that the server supports higher memory frequencies than the Intel processor specification. You can, for example, use low-voltage DIMMs but still operate them at the rated speed.

The following table lists the memory options that are available for the x3750 M4 server.

The following rules apply when selecting the memory configuration:

• The server supports RDIMMs and LRDIMMs. UDIMMs are not supported.
• 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 a case, all DIMMs operate at 1.5 V.
• The 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 processors installed. The table shows the maximum when all four processors are installed. When two processors are installed, the maximum quantity supported is a half of the quantity that is shown.
• 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 processor.
  • 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 the table.

Table highlighting:

• The memory speeds highlighted in bold text indicate that the System x3750 M4 supports higher memory frequencies than the Intel processor specification. In some instances, this configuration also results larger memory capacity that the specification recommends.
• Tables cells highlighted with a grey background indicate when the specific combination of DIMM voltage and number of DIMMs per channel still allows the DIMMs to operate at rated speed

* Maximum quantity supported is shown for four processors installed. When two processors are installed, the maximum quantity supported is a half of the quantity that is shown. When one processor is installed, the quantity is one quarter of that shown.

The following memory protection technologies are supported:

• ECC
• Chipkill (for x4-based memory DIMMs -- look for "x4" in the DIMM description)
• Memory mirroring
• Memory rank sparing

If memory mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per 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 server can support up to 16x 2.5-inch drives, up to 32x 1.8-inch drives, or a combination of both 2.5-inch and 1.8-inch hot-swap drives, using the supported SAS/SATA backplane configurations. The server supports 2.5-inch hot-swap SAS or hot-swap SATA hard disk drives, 2.5-inch hot-swap SATA solid-state drives, or 1.8-inch hot-swap SATA solid-state drives. You can mix drives in the same server as long as you do not mix drives on the same array.

Backplanes

System x3750 M4 server supports a variety of internal storage configurations based on four different backplanes:

• 4-drive backplane for 2.5-inch drives: Up to four backplanes can be installed, each requiring one SAS connection to a supported controller. One RAID controller can connect to two of these backplanes.
• 8-drive backplane for 2.5-inch drives: Up to two backplanes can be installed, each requiring two SAS connections. One RAID controller per backplane.
• 8-drive backplane with a SAS expander for 2.5-inch drives: Use in conjunction with the other 2.5-inch drive backplanes (8-drive or one 4-drive or two 4-drive backplanes) which will result in being able to connect up to 16 2.5-inch drive bays to the one RAID controller.
• 8-drive backplane for 1.8-inch solid-state drives (eXFlash Pack): Up to four backplanes can be installed, each requiring two SAS connections. One RAID controller per backplane. Cannot be connected to the 8-drive backplane with a SAS expander.

When building drive backplane configurations, all 1.8-inch SSD drive backplanes must be installed to the right of all 2.5-inch HDD or 2.5-inch SSD drive backplanes (when looking at the front of the server). Every four drives uses a SAS signal cable except when the 8-drive backplane with SAS expander is used. When the 8-drive backplane with SAS expander is used, the other backplanes connect to the SAS expander backplane with the supplied cables and then the SAS expander backplane is connected to the single RAID controller with two cables. All backplane options include the necessary cables.

See the System x3750 M4 Installation and Service Guide for a description of all supported backplane combinations.

Standard models (all models except A2x) ship with at least one backplane; see Table 2 for details. The following table shows the backplane options that are available for a x3750 M4 server.

Table 6. Internal storage expansion options

* When a server is ordered via CTO, only one 4-drive backplane can be selected. If the order has more than 4 drive bays, 8-drive backplanes will be selected instead.
** Only one backplane with SAS expander (88Y7421) can be installed in a server and can be used connected to a single 8-drive backplane (88Y7419), a single 4-drive backplane (88Y7418), or two 4-drive backplanes (88Y7418). The SAS expander backplane cannot be used with the eXFlash backplane.
