IBM System x3850 X5 Implementation Guide

60 IBM eX5 Implementation Guide
The MAX5 has the following specifications:
򐂰 IBM EXA5 chip set.
򐂰 Intel memory controller with eight memory ports (four DIMMs on each port).
򐂰 Intel QuickPath Interconnect (QPI) architecture technology to connect the MAX5 to the
x3850 X5. Four QPI links operate at up to 6.4 gigatransfers per second (GT/s).
򐂰 Scalability:
– Connects to an x3850 X5 server using QPI cables.
򐂰 Memory DIMMs:
– Minimum: 2 DIMMs, 4 GB.
– Maximum: 32 DIMM connectors (up to 512 GB of memory using 16 GB DIMMs).
– Type of DIMMs: PC3-10600, 1067 MHz, ECC, and DDR3 registered SDRAM DIMMs.
– Supports 2 GB, 4 GB, 8 GB, and 16 GB DIMMs.
All DIMM sockets in the MAX5 are accessible regardless of the number of processors
installed on the host system.
򐂰 Five hot-swap 40 mm fans.
򐂰 Power supply:
– Hot-swap power supplies with built-in fans for redundancy support.
– 675-watt (110 - 220 V ac auto-sensing).
– One power supply standard, two maximum (second power supply is for redundancy).
򐂰 Light path diagnostics LEDs:
–Board LED
– Configuration LED
– Fan LEDs
– Link LED (for QPI and EXA5 links)
– Locate LED
– Memory LEDs
– Power-on LED
– Power supply LEDs
򐂰 Physical specifications:
– Width: 483 mm (19.0 in.)
– Depth: 724 mm (28.5 in.)
– Height: 44 mm (1.73 in.) (1U rack unit)
– Basic configuration: 12.8 kg (28.2 lb.)
– Maximum configuration: 15.4 kg (33.9 lb.)
With the addition of the MAX5 memory expansion unit, the x3850 X5 gains an additional
32 DIMM sockets for a total of 96 DIMM sockets. Using 16 GB DIMMs means that a total of
1.5 TB of RAM can be installed.
All DIMM sockets in the MAX5 are accessible, regardless of the number of processors
installed on the host system.
Figure 3-5 on page 61 shows the ports at the rear of the MAX5 memory expansion unit. The
QPI ports on the MAX5 are used to connect to a single x3850 X5. The EXA ports are
reserved for future use.
