1 HP Integrity Superdome 2 system overview

The HP Integrity Superdome 2 is a blade-based, high-end server platform supporting the Intel
Itanium 9300 and 9500 processor family. Superdome 2 incorporates a modular design to enable
increased scalability through the addition of server blades and external I/O enclosures. Superdome
2 complexes use the sx3000 crossbar fabric to interconnect CPU, memory and I/O resources into
hard (nPartition) and/or virtual (vPar) partitions. Superdome 2 also includes remote system
management functionality through the HP Onboard Administrator, which helps monitor and manage
complex resources, including partitioning.
NOTE: HP Integrity Superdome 2 is not an upgrade to existing Superdome sx1000 and sx2000
systems. HP Integrity Superdome 2 incorporates all new components, including server blades and
blade enclosures.

Complex components

A Superdome 2 complex consists of the following components:
Minimum of one Superdome 2 compute enclosure—The compute enclosure contains the server
blades, I/O interconnect modules (for blade-based I/O), manageability modules of the
complex, and an integrated LCD Insight Display that can be used for basic enclosure
maintenance and displays the overall enclosure health. An SD2-8s complex is a single compute
enclosure capable of supporting up to eight Superdome 2 server blades, but is limited to
maximum of four server blades per partition. An SD2- 1 6s complex is a single compute enclosure
supporting up to eight server blades with a maximum of 8 server blades per partition. A
SD2-32s complex consists of two compute enclosures each supporting up to eight server blades
with a maximum of 16 server blades per partition.
Two Intel Itanium 9300 or 9500 series processors and 32 DDR3 DIMM memory sockets per
blade.
NOTE:
compute enclosure 1 in a Superdome 2 complex. All enclosures must have either a Superdome
2 server blade or a CAMnet completer module installed in the first and second Blade slots to
ensure CAMnet interconnect redundancy.
Up to eight Superdome 2 I/O expansion enclosures for SD2- 1 6s and SD2-32s complexes or
up to four IOX enclosures for SD2-8s complexes.
HP Integrity Superdome 2 SD2- 1 6s and SD2-32S complexes that are factory-integrated also include
an LCD touchscreen display on the rack door that displays the overall complex health and can be
used to access basic complex information.

Power subsystem

Superdome 2 compute enclosures support two power input modules, using either single phase or
3-phase power cords. Connecting two ac sources to each power input module provides 2N
redundancy for ac input and dc output of the power supplies. SD2–32s, SD2–16s, and SD2–8s
complexes contain 12 power supplies per compute enclosure to provide a fully loaded system with
the required power. SD2–8s complexes can contain a minimum of six power supplies if less than
four server blades are present and redundant power grids are not required. Twelve power supplies
give 2N redundancy, which can support the failure of a power supply or an ac power source (but
not simultaneously). Six power supplies are installed in the upper section of the enclosure, and six
power supplies are installed in the lower section of the enclosure.
