So this year will mark the history of the Symmetrix products, 20 years since its inception and the Symmetrix has come long ways. Initially released in 1990, today’s Symmetrix does not come any close to what the product was 20 years ago. The underlying code (Enginuity) is what drives and gives the Symmetrix its personality. Symmetrix was a compute / storage beast 20 years ago and so it is today.

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.

In this post we will cover some important aspects / properties / characteristics / differences between the EMC Symmetrix DMX-4 and EMC Symmetrix V-Max. It seems like a lot of users are searching on blog posts about this information.
From a high level, I have tried to cover the differences in terms of performance and architecture [...]

Here is some information on Cache Only Virtual Devices. I do not have a very clear picture on the overall operation of this device type, but from a high level it can be summed up as following based on it characteristics.

EMC Symmetrix V-Max systems were introduced back in the month of April 2009. With this new generation of Symmetrix came a new name V-Max and a new Enginuity family of microcode 5874.

In this blog post we will discuss the supported drive models for EMC Symmetrix DMX-4. Right before the release of Symmetrix V-Max systems, in early Feb 2009 we saw some added support for EFD’s (Enterprise Flash Disk) on the Symmetrix DMX-4 platform. The additions were denser 200GB and 400GB EFD’s.

In this blog post we will cover the Vaulting technology related to the EMC Symmetrix V-Max and the DMX-4 technology. Vaulting is a key feature added on DMX-3 series of machines, which was further extended into the DMX-4’s and now the Symmetrix V-Max Systems. With power outages or major power fluctuations or other critical environmental conditions (temperature, water, fire and environmental hazards) in data centers, the vaulting technology saves all the data during the shutdown of the machine offering additional safety features with the customer’s data in transit (channels, cache – memory, etc).

In my previous posts on EMC Symmetrix 3, 5, 8 Series and EMCSymmetrix DMX, DMX-2 Series we discussed some important components comprised in these systems. In this post we will discuss components of EMC Symmetrix DMX-4.

There has been a big chatter about the next generation of EMC machines. After the initial release of DMX-3’s in 2005 and then the DMX-4’s in 2007, next generation DMX is almost due now. Here is my wish list or expectations on the new DMX Platform.
