HP Cluster Platform Server and Workstation Overview

4.11.5 Memory Options
You can expand server memory by installing PC2-5300 registered DDR2 SDRAM DIMMs. The
server supports up to 32 GB of memory using eight 4-GB DIMMs (four DIMMs per processor).
Observe the following guidelines when installing additional memory:
• Install only ECC PC2-5300 registered DDR2 SDRAM DIMMs that meet the following
specifications:
— Supply voltage: 1.8 V
— Bus width: 72 bits
• Observe the following special conditions when installing memory with a second processor:
— Processor 2 can be installed without memory.
— Any memory installed into banks for processor 2 can be used only if processor 2 is
installed.
• DIMMs must always be installed in pairs.
• HP recommends installing DIMMs with the greatest capacity in the banks farthest from
each populated processor first.
• DIMMs installed in the same memory bank must have the same part number.
• DIMMs installed in different banks can be of different sizes.
For the latest memory configuration information, see the QuickSpecs on the HP web page:

For memory options information, see the HP ProLiant BL465c Server Blade User Guide.
4.11.6 Mezzanine HCA Card
In HP Cluster Platform systems with InfiniBand, HP ProLiant BL465c server blades are
preconfigured with an InfiniBand mezzanine HCA for the HP c-Class BladeSystem that maps
to the HP 4x DDR InfiniBand Switch Module installed in the rear of the c-Class enclosure.
4.11.7 Supported Storage
The HP ProLiant BL465c supports up to two optional Hot Plug Serial Attach SCSI (SAS) drives
for a maximum of 144GB (2 x 72GB Serial SCSI) internal storage or up to two optional Hot Plug
Serial ATA (SATA) drives for a maximum of 120GB (2 x 60 GB Serial ATA) internal storage.
The physical aspect of inserting and removing a disk drive is discussed in the document that
comes with the drive and in the HP ProLiant BL465c Server Blade User Guide.
Two optional Fibre Channel HBAs are supported by the HP ProLiant BL465c. Both mezzanine
circuit boards connect directly to the server blade system board. These Fibre Channel HBAs are
available via option kits and must be ordered separately.
