Compatibility
The IBM Flex System x240 Compute Node contains licensed system programs that
include set configuration, set features, and test programs. IBM system BIOS is
loaded from a "flash" EEPROM into system memory. This BIOS provides instructions
and interfaces designed to support the standard features of the x240 Compute Node
and to maintain compatibility with many current software programs.
Contact your IBM representative or IBM Business Partner, or refer to the IBM Sales
Manual for information on the compatibility of hardware and software for System x
servers. The Sales Manual is updated periodically as new features and options are
announced that support these servers.
Limitations
• The Flex System x240 Compute Nodes contain 24 DIMM sockets. A maximum
of 768 GB of system memory is supported by using a 32 GB DIMM of ECC DDR3
memory in each of the DIMM sockets. A minimum of one memory feature must
be installed. All memory installed must be of the same type (RDIMM, LR DIMM,
or UDIMM).
• Processor modules must be of the same type, power level, and clock speed on
each Flex System x240 Compute Node. Mixing processor modules of different
speeds, power levels, or cache sizes or upgrading the base processors is not
