HP 3PAR StoreServ 7000 Storage System Components HP 3PAR storage systems utilize a cluster-based design that incorporates sophisticated data management and fault tolerance technologies that can meet the storage needs of smaller sites and can easily be scaled for global organizations. The HP 3PAR StoreServ 7000 is compatible with most industry-standard 4-post EIA 19-inch racks with square mounting holes, including the HP Intelligent Series Rack and the HP 10000 G2 Series Rack. The HP 3PAR StoreServ 7000 can be factory configured and shipped in a rack, or shipped without a rack for field integration into an existing rack. The rack used for factory integration is the HP Intelligent Series Rack.

1 System Components and Specifications
This chapter provides detailed system specifications for the HP 3PAR StoreServ 7000 Storage
system and serves as a quick reference for other relevant specifications that are described in more
detail in other chapters of this manual.
HP 3PAR StoreServ 7000 Storage System Components
HP 3PAR storage systems utilize a cluster-based design that incorporates sophisticated data
management and fault tolerance technologies that can meet the storage needs of smaller sites and
can easily be scaled for global organizations.
The HP 3PAR StoreServ 7000 is compatible with most industry-standard 4-post EIA 19–inch racks
with square mounting holes, including the HP Intelligent Series Rack and the HP 10000 G2 Series
Rack. The HP 3PAR StoreServ 7000 can be factory configured and shipped in a rack, or shipped
without a rack for field integration into an existing rack. The rack used for factory integration is
the HP Intelligent Series Rack.
The storage system is comprised of the following components:
•
Controller nodes are components in the storage system that work to cache and manage data
and provide hosts with a coherent, virtualized view of the system. Controller nodes are located
in the rear of the node enclosure.
◦
The HP 3PAR StoreServ 7200 Storage system includes two nodes (Node 0 and Node
1).
◦
The HP 3PAR StoreServ 7400 Storage system can include two nodes or four nodes (Nodes
0 and 1 on the lower controller and Nodes 2 and 3 on the upper controller in a system
with four nodes).
◦
The HP 3PAR StoreServ 7200 and 7400 (two-node) Storage enclosures hold up to 24,
2.5 inch small form-factor (SFF) Serial Attached SCSI (SAS) disk drives arranged vertically
in a single row. The back of the enclosure includes two 764 W power cooling modules
(PCM) and two controller nodes.
◦
The HP 3PAR StoreServ 7400 (four-node) Storage enclosure holds up to 48, 2.5 inch SFF
SAS disk drives arranged in two vertical rows. The back of the enclosure includes four
764 W PCMs and four controller nodes.
NOTE:
Controller nodes of the 7200 and 7400 are unique to the system type and are not
interchangeable.
•
Drive enclosures hold an array of disk drives. These are intelligent, compact, extremely dense
storage units, where each is capable of holding a large numbers of disk drives in a small rack
space (EIA-standard rack units).
◦
The HP M6710 Drive Enclosure (2U24) holds up to 24, 2.5 inch small form factor (SFF)
SAS disk drives, installed vertically in a single row at the front of the enclosure. The back
of the enclosure contains two 580 W PCMs and two I/O modules.
◦
The HP M6720 Drive Enclosure (4U24) holds up to 24, 3.5 inch large form factor (LFF)
SAS disk drives, installed horizontally with four columns of six disk drives. The back of
the enclosure contains two 580 W PCMs and two I/O modules.
•
I/O Modules connect the controller nodes to the drives using SAS cables, enabling the transfer
of data between the nodes, the drives, PCMs, and enclosures. The I/O modules are located
at the rear of the drive enclosure and are numbered 0 to 1 from bottom to top. There are two
I/O modules per enclosure.
