Įach 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.Įach VMAX system supports up to 10 storage bays for hard drives. The system grows by aggregating up to eight Symmetrix VMAX engines in a single system with fully shared connectivity, processing, memory and storage capacity resources. The VMAX system features a bay containing one to eight engines and separate rollup storage bays.
VMAX systems are high-end, scalable storage platforms intended for open systems and mainframe computing. These components were integrated into the VMAX engine, which includes a pair of highly-available directors with dual Virtual Matrix Interconnects. The core components of the Symmetrix Direct Matrix Architecture consisted of two back-end director boards, two memory boards, and two front-end boards. VMAX, VMAXe, VMAX-SE, VMAX 10K, VMAX 20K, VMAX 40K All-Flash systems accounted for 80% of all VMAX revenue as of May, 2017 according to IDC. All-Flash versions of the product line were introduced in 2016, further increasing system scalability, reliability and sub-millisecond latency.

Since the introduction of VMAX, development has continued on both the hardware and software fronts, including the original Enginuity operating system, which was replaced by the HYPERMAX OS when the VMAX3 line was introduced in 2014 with a built-in storage hypervisor. The new architecture could support “hundreds of thousands of terabytes of storage and millions of IOPS (input/output per second) supporting hundreds of thousands of VMware and other virtual machines in a single federated storage infrastructure.” VMAX (then called EMC Symmetrix V-Max) was the first storage system to support this new scale out architecture offering from 1 engine to 8 engines of expansion. In 2009, EMC introduced the Virtual Matrix Architecture, which was a re-design of the DMX architecture to reflect the ongoing virtualization trend. The Symmetrix DMX Architecture featured Channel Directors for host communication, Disk Directors for disk communication, and Global Memory Directorsįor I/O delivery from hosts to Disk Directors. This architecture replaced older switch- and bus-based architectures, offering significant performance improvements in the process. The Direct Matrix Architecture (DMX) product line was announced in February 2003. 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. 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.
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. The 1995 release of Symmetrix 3000 was recognized as the first open system to connect to mainframe-class storage over standard SCSI protocols. Newer generations of Symmetrix brought additional host connection protocols which include ESCON, SCSI, Fibre Channel-based storage area networks (SANs), FICON and iSCSI. The first Symmetrix systems were storage arrays connected to an IBM mainframe via the block multiplexer channel. Symmetrix was EMC Corporation's flagship product from 1990, when it first shipped, until 2003 when the Direct Matrix Architecture (DMX) product line was introduced to replace it. It evolved out of the EMC Symmetrix array, EMC’s primary storage product of 1990s and early 2000s. /storage/vmax-all-flashĭell EMC VMAX is Dell EMC’s flagship enterprise storage array product line.
