IBM System x3755 M3

IBM Redbooks Product Guide

The IBM® System x3755 M3 is a four-socket AMD Opteron processor-based server that is optimized for
outstanding density and cost. It provides flexibility and scalability while offering multiple levels of
price/performance. With features such as high performance AMD Opteron 6300 series processors, up to
32 available DIMM sockets with up to 512 GB of memory , and robust I/O, the System x3755 M3 provides
four-socket performance at an entry-level price.

The x3755 M3 is an ideal server for business workloads including database, virtualization, Java, and
enterprise applications such as ERP. The increased processor density helps reduce networking
complexity and cost for high-performance computing environments, and the available 32 TB of internal
storage facilitates data-intensive applications like business intelligence.

Figure 1 shows the IBM System x3755 M3.

Did you know?

IBM System x3755 M3 fits into 2U of standard rack space, and it can be used as a very affordable
dual-socket 2U rack platform with the ability to grow to four sockets in the same space, or as a very dense
space-optimized and price/performance-optimized four-socket enterprise-class server for business critical
corporate applications. High availability, manageability, and performance features include Chipkill
memory, Memory Sparing, Light Path Diagnostics, Predictive Failure Analysis, TCP Offload Engine
(TOE), and integrated baseboard management controller (iBMC) with activated built-in remote presence
feature.

The IBM System x3755 M3 supports up to 16 DIMMs when two processors are installed and up to 32
DIMMs when four processors are installed. Each processor has four memory channels, and there are two
DIMMs per channel.

The following rules apply when selecting the memory configuration:



All configurations support RDIMMs



Models with AMD Opteron 6200 processors also support UDIMMs



Mixing different types of memory (UDIMMs and RDIMMs) is not supported.



Mixing 1.5 V and 1.35 V DIMMs is supported, except in CTO configurations built in the factory. If 1.5
V and 1.35 V DIMMs are mixed, all DIMMs operate at 1.5 V

IBM System x3755 M3 8



Minimum of 2 DIMMs must be installed per processor



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 the following
table.



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 "Maximum
operating speed" section in the table.

The following two tables show the characteristics of the supported DIMMs. Table 6 is for models with
AMD Opteron 6300 processors and Table 7 is for models with AMD Opteron 6200 processors. 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 following memory protection technologies are supported:



ECC



ChipKill (for x4 and x8-based DIMMs)



Memory sparing

Note: Memory Sparing is not supported with quad-rank DIMMs.

The RAID controller is installed into dedicated PCI-E slot 4 (Figure 4). Simple Swap SATA models only
support the ServeRAID BR10il v2 controller. The BR10il v2 supports up to four SS SATA HDDs, and the
remaining two SATA HDDs can be used as standalone drives that are not part of a RAID array. Hot swap
SAS/SATA models do not support ServeRAID BR10il v2.

If the ServeRAID M5014 or M5014 controller is specified with a battery, it can be used in the x3755 M3.
However, the battery is installed separately on a remote battery tray and connected to the RAID controller
via the ServeRAID M5000 Series Battery Remote Mount Cable, 68Y7396. Installing the battery remotely
is done to avoid overheating. The remote battery tray is shipped standard with the server and is attached
to the side of the chassis.

The ServeRAID BR10il v2 SAS/SATA Controller has the following specifications:



One Mini-SAS internal connector



Supports RAID levels 0, 1, and 1E



3 Gbps throughput per port



Based on the LSI 1064E controller
