ESAM components
A typical configuration consists of two P9500 storage systems installed at the primary and secondary
sites. In addition, the ESAM system consists of the following components:
•
ESAM and Continuous Access Synchronous software, which are installed on both systems.
•
A host server running a multipath software solution, qualified with ESAM software, that is
connected to both storage systems.
•
Dedicated Fibre Channel data paths linking the primary and secondary storage systems, with
Fibre Channel switches.
•
A qualified external storage system to host the quorum disks. This storage system must be
accessible to both the primary and secondary storage systems.
•
The following interface tools for configuring and operating the pairs:
Remote Web Console (RWC) graphical user interface (GUI), located on a management
LAN. ◦
◦ RAID Manager (RAID Manager), located on the host.
ESAM components are illustrated in the following figure and described in more detail in the

P9500 storage systems
ESAM operations are conducted between P9500 (P9500) and another storage system on the
primary and secondary sites. The primary storage system consists of the main control unit (MCU)
and service processor (SVP). The secondary storage system consists of the remote control unit (RCU)
and SVP.
The primary storage system communicates with the secondary storage system over dedicated Fibre
Channel remote copy connections.
