What your compute node offers
The design of the compute node takes advantage of advancements in chip technology, memory
management, and data storage.
The compute node uses the following features and technologies:
v Service processor
The service processor for the IBM Flex System p24L Compute Node provides support for the following
functions:
– Intelligent Platform Management Interface (IPMI)
– The operating system
– Power control and advanced power management
– Reliability, availability, and serviceability (RAS) features
– Serial over LAN (SOL)
– Continuous health monitoring and control
– Configurable notification and alerts
– Event logs that are time stamped and saved in nonvolatile memory and that can be attached to
email alerts
– Point-to-Point Protocol (PPP) support
– Remote power control
– Remote firmware update and access to critical compute node settings
v Disk drive support
The compute node supports either Serial Advanced Technology Attachment (SATA) solid-state drives
(SSDs) or serial-attached SCSI (SAS) hard disk drives (HDDs) in one of the following configurations:
– Up to two 1.8 in. SATA SSDs
– Up to two 2.5 in. SAS HDDs
v Impressive performance using the latest microprocessor technology
The compute node comes with two POWER7 microprocessors for the IBM Flex System p24L Compute
Node.
v I/O expansion
The compute node has connectors on the system board for optional PCI Express (PCIe) network
adapter cards for adding more network communication capabilities to the compute node.
v Large system memory capacity
The memory bus in the IBM Flex System p24L Compute Node supports up to 512 GB of system
memory. For the official list of supported DIMMs, see http://www.ibm.com/systems/info/x86servers/
serverproven/compat/us/ (http://www-03.ibm.com/servers/eserver/serverproven/compat/us/).
v Light path diagnostics
Light path diagnostics provides light-emitting diodes (LEDs) to help diagnose problems. An LED on
the compute node control panel is lit if an unusual condition or a problem occurs. If this happens, you
can look at the LEDs on the system board to locate the source of the problem.
v Power throttling
If your IBM Flex System Enterprise Chassis supports power management, the power consumption of
the compute node can be dynamically managed through the management module. For more
information, see http://publib.boulder.ibm.com/infocenter/flexsys/information/topic/
