Memory options
TruDDR4 Memory uses the highest quality components that are sourced from Tier 1 DRAM suppliers and
only memory that meets the strict requirements of IBM is selected. It is compatibility tested and tuned on
every IBM System x server to maximize performance and reliability. TruDDR4 Memory has a unique
signature that is programmed into the DIMM that enables IBM System x servers to verify whether the
memory that is installed is qualified or supported by IBM. Because TruDDR4 Memory is authenticated,
certain extended memory performance features can be enabled to extend performance over industry
standards. From a service and support standpoint, IBM memory automatically assumes the IBM system
warranty and IBM provides service and support worldwide.
The following table lists the supported memory options.

The server supports up to 12 TruDDR Memory 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 memory channel (3 DPC). RDIMMs and LRDIMMs are supported, but the mixing of
these different types is not supported. UDIMMs are not supported. DIMMs can be installed individually;
however, install them in sets of four (one for each of the four memory channels) for performance reasons.
The following rules apply when the memory configuration is selected:
Mixing of different types of DIMMs (RDIMM and LRDIMM) in the same server is not supported.

The maximum number of supported ranks per channel is eight.

The maximum quantity of DIMMs that can be installed in the server depends on the number of CPUs,

DIMM rank and operating voltage, as shown in the "Maximum quantity" row in the following table. The
shaded cells indicate that the DIMM type supports the maximum number of DIMMs (24 for the x240
M5).

IBM Flex System x240 M5 Product Guide 13
All DIMMs in all CPU memory channels operate at the same speed, which is determined as the

lowest value of the following factors:
Memory speed that is supported by the specific CPU.

Lowest maximum operating speed for the selected memory configuration that depends on rated

speed, as shown in the "Maximum operating speed" section in the following table. The shaded
cells indicate that the speed indicated is the maximum that the DIMM allows.
The following table shows the maximum memory speeds that are achievable based on the installed
DIMMs and the number of DIMMs per channel. The table also shows the maximum memory capacity at
any speed that is supported by the DIMM and maximum memory capacity at rated DIMM speed. In the
table, cells that are highlighted in gray indicate when the specific combination of DIMM voltage and

The following memory protection technologies are supported:
ECC

Memory mirroring

Memory sparing

If memory mirroring is used, 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, 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 to be 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 that are installed.

IBM Flex System x240 M5 Product Guide 14
Internal storage
The x240 M5 server has two 2.5-inch hot-swap drive bays that are accessible from the front of the blade
server (see Figure 2). These bays connect to the integrated LSI SAS3004 12 Gbps SAS/SATA
RAID-on-Chip (ROC) controller.
The integrated LSI SAS3004 ROC has the following features:
Four-port LSI SAS3004 controller with 12 Gbps throughput per port

PCIe x4 Gen 2 host interface

Two SAS ports routed internally to the two hot-swap drive bays

Supports RAID-0, RAID-1 and RAID-1E

The two 2.5-inch front-accessible drive bays can be replaced with four 1.8-inch drive bays, two 1.8-inch
bays replacing each 2.5-inch bay, by using the ServeRAID M1200 RAID 5 Enablement Kit, 00JX141. This
kit contains a replacement backplane to connect the four 1.8-inch SSDs. The kit also includes ServeRAID
M1200 Zero Cache/RAID 5 Upgrade (Feature on Demand license), which adds RAID 5 support. The part
number for this upgrade is listed in the table.
The two standard 2.5-inch SAS/SATA drive bays can also be replaced with new PCIe NVMe
(Non-Volatile Memory Express) drives that are directly connected to the PCIe bus of the second
processor. Such connectivity, when combined with SSD drives, ensures the lowest possible latency while
still using a standard drive form factor.
Support for NVMe drives requires a replacement drive backplane for the two 2.5-inch drives plus the
second processor must also be installed in the server. The kit containing the backplane, NVMe Enterprise
PCIe SSD Enablement Kit for IBM Flex System x240 M5, is listed in the following table.
