System x3755 M3

The 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 System x3755 M3.

Lenovo DDR3 memory is compatibility tested and tuned for optimal System x performance and throughput. DDR3 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, and provides service and support worldwide.

The following tables lists memory options available for the x3755 M3 server.

Table 5. Memory options for systems with AMD Opteron 6200 processors

The 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
• 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.

Table 5. Maximum memory speeds for systems with AMD Opteron 6300 processors

* The maximum quantity that is supported is shown for four processors installed.

Table 6. Maximum memory speeds for systems with AMD Opteron 6200 processors

* The maximum quantity that is supported is shown for four processors installed.

The System x3755 M3 server supports the following internal storage configurations:

• Six 3.5" Simple-Swap SATA drive bays (only available via CTO)
• Eight 3.5" Hot-Swap drive bays supporting SAS or SATA drives

The following table lists the RAID controllers and additional options used for internal disk storage of the x3755 M3 server.

Table 7. RAID controllers for internal storage

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 server does not support high IOPS SSD adapters.

The server supports up to three 1100-watt, hot-swap power supplies that support N+N or N+1 redundancy depending on the configuration:

• If only two or three processors are installed or four processors less than 140 W are installed, then one power supply is required and the second supply can be redundant if installed (N+N where N=1)
• If four 140W processors are installed, then two power supplies are required for a fully-populated server with no redundancy (or three power supplies can be installed with the third redundant N+1, where N=2)
• If four 140W processors are installed, only one power supply can be installed with no redundancy (or two power supplies can be installed with the second redundant, N+1 where N=1) provided these limits are met:
  • Maximum 16 DIMMs
  • Maxumum 4 disk drives

The server comes standard with one or two power supplies, depending on the model. The following table lists the power supplies.

Table 12. Power supplies

Each power supply ships standard with one 2.8 m, 10A/100-250 V, C13 to IEC 320-C14 Rack Power Cable.

The server supports VMware ESXi installed on a USB memory key. The key is installed in a USB socket inside the server. The following tables lists the virtualization options.

Table 13. Virtualization options for systems with AMD Opteron 6300 processors

Table 15. Virtualization options for systems with AMD Opteron 6200 processors

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) Trap
• 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.
