The ES7000 Model 7600R G2 Server
in a given location might exceed the average stated values because of room
reflections and other nearby noise sources. The declared sound-power levels indicate
an upper limit, below which a large number of computers will operate.
What the Memory Expansion Module offers
The following table contains a summary of the features and specifications of the Memory
Expansion Module.
• Customer replaceable units (CRUs)
The major CRUs in the Memory Expansion Module are memory modules, fans, and
power supplies. See Memory Expansion Module componentsfor the supported
memory components.
• Light path diagnostics LEDs
The Memory Expansion Module has light path LEDs (front and rear) to indicate
hardware, scaling, and power problems.
• Redundant cooling and power capabilities
The Memory 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 memory drawer expansion 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.
• Large memory capacity
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).
Memory Expansion Module RAS 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 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:
• 1-year parts and 1-year labor limited warranty or it assumes the warranty of the
ES7000 Model 7600R G2 server when attached, whichever is longer.
• Chipkill memory protection
• Hot-swap and redundant cooling with fan-speed-sensing capability (front
serviceability)
