What The Max5 Offers; Max5 Reliability, Availability, And Serviceability Features - IBM System x3690 X5 Installation And User Manual

What the MAX5 offers

The IBM MAX5 for System x (MAX5) memory expansion module provides several
features for easy operation, including the following features:
v Customer replaceable units (CRUs)
v Light path diagnostics LEDs
v Redundant cooling and power capabilities
v Large memory capacity

MAX5 reliability, availability, and serviceability features

Three of the most important features in product design are reliability, availability,
and serviceability (RAS). These factors help to ensure that the integrity of the data
processed in your MAX5 memory expansion module is preserved, that the
expansion module is available when you want to use it, and should a failure occur,
you can easily diagnose and repair the failure with minimal inconvenience.
The following is an abbreviated list of the RAS features that the expansion module
supports:
v 1-year parts and 1-year labor limited warranty or it assumes the warranty of the
v Chipkill memory protection
v Hot-swap and redundant cooling with fan-speed-sensing capability (front
v Hot-swap and redundant power supplies (rear serviceability)
v Information LED panel
v In-rack serviceability
v Memory redundant bit steering (RBS) and error correcting code (ECC)
v Memory mirroring support (mirrored DIMMs are mutually exclusive of each
v QuickPath Interconnect (QPI) fail down
v Rear serviceability power supplies

The major CRUs in the MAX5 expansion module are memory modules, fans,
and power supplies. See "MAX5 components" on page 117 for the supported
MAX5 components.
The MAX5 expansion module has light path LEDs (front and rear) to indicate
hardware, scaling, and power problems.
The MAX5 expansion module supports a maximum of two 675-watt hot-swap
power supplies and five single-motor hot-swap fans, which provides
redundancy and hot-swap capability. The redundant cooling by the fans enables
continued operation if one fan fails. The MAX5 comes with one 675-watt
hot-swap power supply and five fans. If a problem occurs with one of the power
supplies, the other power supply can meet the power requirements.
The memory bus supports up to 512 GB of memory. The memory controller
supports error correcting code (ECC) for up to 32 industry-standard 1066 MHz
PC3-10600R-999 or 1333 MHz PC3-8500, DDR3 (third-generation
double-data-rate), registered, synchronous dynamic random access memory
(SDRAM) dual inline memory modules (DIMMs).
