SRDF logically pairs a device or a group of devices from each array and replicates data from one to the other synchronously or asynchronously. An established pair of devices can be split, so that separate hosts can access the same data independently (maybe for backup), and then be resynchronised.
666:
Asynchronous SRDF (SRDF/A) transfers changes made to the secondary array in units called delta sets, which are transferred at defined intervals. Although the remote copy of the data will never be as current as the primary copy, this method can replicate data over considerable distances and with
662:
In synchronous mode (SRDF/S), the primary array waits until the secondary array has acknowledged each write before the next write is accepted, ensuring that the replicated copy of the data is always as current as the primary. However, the latency due to propagation increases significantly with

The
Symmetrix VMAX system bay can hold one to eight engines. These engines house the hardware for all the data processing capabilities. Each engine contains two director boards, memory chips, and front-end (FE) and back-end (BE) ports for connectivity to hosts and storage bays, respectively.
617:
Each director board contains two Intel quad-core processors for data processing, 16, 32 or 64 GB of physical memory, one System
Interface Board (SIB) that connects the director to the Matrix Interface Board Enclosure (MIBE), front-end and back-end ports.

Other forms of SRDF integrate with clustered environments and to manage multiple SRDF pairs where replication of multiple devices must be consistent (such as with the data files and log files of a database application).

The VMAX has one to ten storage bays for hard drives. Each storage bay contains 16 Disk Array
Enclosures (DAE). Each DAE contains 15-25 hard drives. VMAX supports SATA, Fiber Channel, SAS and Solid State drives.
