IBM System x3755 M3
IBM System x at-a-glance guide
The IBM® System x3755 M3 is a low-cost, four-socket AMD Opteron processor-based server that is
optimized for outstanding density. It provides flexibility and scalability while offering multiple levels of
price/performance. With features such as high performance AMD Opteron 6200 series processors, up to
32 available DIMM sockets with up to 512 GB of DDR3 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 24 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.

Memory options
The IBM System x3755 M3 supports DDR3 memory. The server supports up to 16 DIMMs when two
processors are installed and up to 32 DIMMs when four processors are installed. The maximum amount of
memory supported by the server of DIMMs is limited by the number of ranks in the DIMMs:
RDIMMs

Up to 32 single-rank RDIMMs (eight per processor) for a maximum of 128 GB (32x 4 GB)

Up to 32 dual-rank RDIMMs (eight per processor) for a maximum of 256 GB (32x 8 GB)

Up to 32 quad-rank RDIMMs (eight per processor) for a maximum of 512 GB (32x 16 GB)

UDIMMs

Up to 32 single-rank UDIMMs (eight per processor) for a maximum of 64 GB (32x 2 GB)

Up to 32 dual-rank UDIMMs (eight per processor) for a maximum of 128 GB (32x 4 GB)

Each CPU has four memory channels, and each of those contains two DIMMs per channel. Maximum
memory speed is limited by the number and type of DIMMs installed, as follows:
1.5 V DIMMs

1333 MHz when one or two single-rank or dual-rank DIMMs per channel are installed

1066 MHz when one or two quad-rank DIMMs per channel are installed

1.35 V DIMMs

1333 MHz when one or two single-rank or dual-rank DIMMs per channel are installed

1066 MHz when one quad-rank DIMM per channel is installed

800 MHz when two quad-rank DIMMs per channel are installed

The server supports both 1.5 V and 1.35 V DIMMs. It is supported to mix 1.5 V and 1.35 V DIMMs in the
same system, but the 1.35 V DIMMs will operate at 1.5 V and lose their energy efficiency. Mixing UDIMMs
and RDIMMs in the same server is not supported. Memory must be installed in pairs, and the DIMMs
within a pair must be identical (capacity, rank, and 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

Remote management
The server contains second-generation Integrated Baseboard Management Controller (iBMC), 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 iBMC lights LEDs to help you diagnose
the problem, records the error in the event log, and alerts you to the problem. In addition, the iBMC also
provides a virtual presence as a standard feature for remote server management capabilities.
The iBMC provides remote server management through industry-standard interfaces:
Intelligent Platform Management Interface (IPMI) Version 2.0

Simple Network Management Protocol (SNMP) Version 3

Web browser

The remote management feature provides the following functions:
Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz, 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 iBMC memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the iBMC restarts the server
when the iBMC detects an operating system hang condition. A system administrator can use the
blue-screen capture feature to assist in determining the cause of the hang condition.
