Required Hardware Components
DRM uses a minimum of two HSG80 Array Controller pairs: one at the initiator site and one
at the target site. Each site must have one or more ESA12000 racks or EMA12000/EMA16000
modular storage racks:
■ RA8000/ESA12000 racks are equipped with one or more BA370 enclosures and disk
storage building blocks (SBBs). Each BA370 enclosure holds up to 24 disks.
■ MA8000/EMA12000/EMA16000 modular storage racks are equipped with one or more
controllers and modular disk SBBs.
The hosts at the initiator and target sites are connected to a pair of dual-redundant HSG80
Array Controllers, which are located inside the enclosures. Connections between the
controllers and hosts are made at each site with two Fibre Channel switches and two host bus
adapters (HBAs). For complete details on this equipment, refer to the storage rack installation
reference guide for your operating system.
Note: Although this documentation addresses ESA12000 storage racks as a primary unit for DRM
configurations, the HP DT solution functions in any equivalent rack that houses a BA370 enclosure.
For the EMA12000/EMA16000 modular storage racks, the HP DT solution functions in any
equivalent rack that houses the same number of controllers and an equivalent drive configuration.
Rack configurations may also be combined between the ESA12000 racks and
EMA12000/EMA16000 modular storage racks. For example, if the disk configurations are
equivalent, an ESA12000 rack may be used at one site (initiator or target) and an
EMA12000/EMA16000 modular storage rack may be used at the associated site (target or
initiator).
Rack Components
Tables and figures throughout this chapter show hardware that is necessary or optional to
complete a modular DRM solution for each of two types of rack configurations, the
ESA12000 rack and the EMA12000/EMA16000 modular storage rack.
