HP Cluster Platform Server and Workstation Overview

Maximum memory capacities for all AMP modes will increase with the availability of 4-GB
FBDIMMs, including a maximum of 32 GB in Advanced ECC mode. For the latest memory
configuration information, see the QuickSpecs at:
http://h18004.www1.hp.com/products/servers/proliant-bl/c-class/460c/specifications.html.
The Advanced Memory Protection option is configured in RBSU. By default, the server is set to
Advanced ECC mode. For more information, see the HP ROM-Based Setup Utility in the HP
ProLiant BL460c Server Blade User Guide. If the configured AMP mode is not supported by the
installed FBDIMM configuration, the system boots in Advanced ECC mode. The following
configuration requirements apply to all AMP modes:
• FBDIMMS must be ECC registered DDR-2 SDRAM FBDIMMs.
• FBDIMMs must be installed in pairs.
• FBDIMM pairs in a memory bank must have identical HP part numbers.
• FBDIMMS must be populated as specified for each AMP memory mode.
The memory subsystem for this server blade is divided into two branches. Each memory branch
is essentially a separate memory controller. The FBDIMMs map to the two branches as indicated
in the following table:
Branch 1Branch 0
FBDIMM 5BFBDIMM 1A
FBDIMM 7BFBDIMM 3A
FBDIMM 6DFBDIMM 2C
FBDIMM 8DFBDIMM 4C
This multibranch architecture provides enhanced performance in Advanced ECC mode. The
concept of multiple branches is important for the operation of online spare mode and mirrored
memory mode.
If the server blade contains more than 4 GB of memory, consult the operating system
documentation about accessing the full amount of installed memory.
For memory options information see the HP ProLiant BL460c Server Blade User Guide.
4.9.6 Mezzanine HCA Card
In HP Cluster Platform, the HP ProLiant BL460c server blades are preconfigured with an HP 4x
DDR IB Mezzanine HCA for the HP c-Class BladeSystem , which works with the HP 4x DDR
InfiniBand Switch Module installed in the rear of the c-Class enclosure. For more information
on the mezzanine HCA card, see the HP ProLiant BL460c Server Blade User Guide. For more
information on the 4x DDR InfiniBand Switch Module, see the HP Cluster Platform InfiniBand
Interconnect Installation and User's Guide.
4.9.7 Supported Storage
The HP ProLiant BL460c supports up to two optional Hot Plug Serial Attach SCSI (SAS) drives
for a maximum of 144 GB (2 x 72 GB 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 BL460c Server Blade User Guide.
Two optional Fibre Channel HBAs are supported by the HP ProLiant BL460c. 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.
