    EMC Symmetrix, 20 Years in the making So next year will mark a history of Symmetrix Products within EMC, still classified as one of the most robust systems out there after 20 years of its inception. In this section, we will talk about some facts on Symmetrix products as it relates to its features, characteristics, Enginuity microcode versions, model numbers, year released, etc.

    So the journey of Symmetrix systems started with Moshe Yanai (along with his team) joining EMC in late 80‘s. A floating story says, the idea of a cache based

    disk array was initially pitched to both IBM and HP and was shot down. EMC was predominately a mainframe memory selling company back in the late 1980‘s. The Symmetrix products completely changed the direction of EMC in a decade.

    Joe Tucci comes in at the end of 90‘s from Unisys with a big vision. Wanted to radically change EMC. Through new acquisitions, new technologies, vision and foremost the integration of all the technologies created today‘s EMC.

    Symmetrix has always been the jewel of EMC. Back in the Moshe days, the engineers were treated so royally (Have heard stories about helicopter rides and lavish parties with a satellite bus waiting outside for a support call). Then comes the Data General acquisition in late 90‘s that completely changed the game.

    Some people within EMC were against the DG acquisition and didn‘t see much value in it. While the Clariion DG backplane is what changed the Symmetrix to a Symmetrix DMX Fiber Based Drives. Over this past decade, EMC radically changes its position and focuses on acquisitions, support, products, quality, efficiency, usability and foremost changing itself from a hardware company to an Information Solutions company focusing on software as its integral growth factor. New acquisitions like Legato, Documentum, RSA, kept on changing the culture and the growth focus within EMC.

    Then came VMware and it changed the rules of the game, EMC‘s strategic move to invest into VMware paid off big time. Then happens the 3-way partnership between VMware EMC Cisco, to integrate next generation products, V-Max (Symmetrix), V-Sphere and UCS are born.

    Here we are in 2009, almost at the end of 20 years since the inception of the Symmetrix, the name, the product, the Enginuity code, the robust characteristics, the investment from EMC all stays committed with changing market demands.
