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 blog post, we will talk about some facts on Symmetrix products as it relates to its features, characteristics, Enginuity microcode versions, model numbers, year released, etc.

Also in this blog post you will see links to most of my previous posts about Symmetrix products.

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.

I could have easily added total memory capacity per frame, total number of dedicated DA/DAF slots, total slots, total universal slots, total memory slots, but then I didn’t know information on some of the old systems and didn’t want to be incorrect on them.

Hope you have enjoyed reading this post, with a bit of history related to the Symmetrix platform. I am pretty positive, as of today you will not find this consolidated information on any blog or the manufacturers website.

I really wish, EMC decided to open blogging to some Symmetrix, Clariion, Celerra, Centera specialist that support these systems on a day to day basis, the information that could come out from those guys could be phenomenal. Barry Burke writes a lot of stuff, but again a lot of FUD from him against IBM and HDS, its great reading him, but only a controlled amount of technical information comes from him.

  • The Torp

    Just tripped across this article. It was very good from the technical aspect and as far as SEs or quality people commenting – furghetaboutit!

    but what I can share having spent several years and working for/within the “brass” of EMC, the technology was one portion (or as Dick Egan’s sign would say “it’s the product stupid” but the people in that hey day were something else. Perhaps akin to a wild west shootout at times. I can say without reservartion if it weren’t for the following, “Don O’Bryant, Dan Butler, Moshe Yania, Tuvia, Jack Egan, Paul Petracca, Moshe Yanai, and finally Dick Egan (and some folks from Marketing whose names elude me but were also key in those days)” then they could have all the technology in the world and it would not have mattered. As I would once say to Dick, ‘it may be the product but it’s the process that builds the product, stupid”. While these decentralized groups of warring tribes ensued – one guy came on board, Mike Ruettgers, who pulled it all together and the rest is history.
