The Symmetrix system is EMC Corporation's enterprise storage array. It was the flagship product of EMC in the 1990s and 2000s.

History[edit]

Symmetrix arrays, EMC's flagship product at that time, began shipping in 1990 as a storage array connected to an IBM mainframe via the block multiplexer channel . Newer generations of Symmetrix brought additional host connection protocols which include ESCON, SCSI, Fibre Channel-based storage area networks (SANs), FICON and iSCSI. The Symmetrix product was initially popular within the airline industry and with companies that were willing to deviate from the safety of IBM's 3390 disk subsystem and take a risk with the unproven Symmetrix array. This product is the main reason for the rapid growth of EMC in the 1990s, both in size and value, from a company valued hundreds of millions of dollars to a multi-billion company.[1] Moshe Yanai managed the Symmetrix development from the product's inception in 1987 until shortly before leaving EMC in 2001,[2] and his Symmetrix development team grew from several people to thousands.

VMAX[edit]

EMC Symmetrix V-Max systems are storage platforms intended for open systems and mainframe computing. Symmetrix V-Max systems run Enginuity operating environment. The system scales from a single Symmetrix V-Max Engine system with one storage bay to a large eight engine system and a maximum of ten storage bays.

The VMAX system bay has 1-8 Engines. These engines house all the hardware for the entire data processing capabilities. Each Engine contains 2 director boards, Memory Chips, Front end and back end ports for connectivity to hosts and storage bays.

Each Director board contains 2 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.

The VMAX has 1 to 10 storage bays, Hard drives are installed in the storage bays, Each Storage bay contains 16 Disk Array Enclosures (DAE). Each DAE contains 15-25 hard drives. The VMAX supports SATA, Fiber Channel, SAS and Solid State drives.[4]
