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. Moshe Yanai managed the Symmetrix development from the product's inception in 1987 until shortly before leaving EMC in 2001, and his Symmetrix development team grew from several people to thousands.

EMC Symmetrix VMAX systems are storage platforms intended for open systems and mainframe computing. Symmetrix VMAX systems run the Enginuity operating environment. The system scales from a single Symmetrix VMAX Engine system with one storage bay to a large eight-engine system with a maximum of ten storage bays.
The VMAX system bay can hold 1-8 engines. These engines house the hardware for all the data processing capabilities. Each engine contains 2 director boards, memory chips, and front-end (FE) and back-end (BE) ports for connectivity to hosts and storage bays, respectively.
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 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.
