To start all things DMX-4 I cede to the Anarchist.
Anyhoo, lots of things happening today and as per usual the devil (And the work) is in the details so lets have a look at the items which I found interesting.
First off, RAID 6:
Something everyone knew was coming but now with the benefit of being able to use the foundational pro-active hot sparing and rebuild logging capabilities introduced in FLARE 24. It was decided a while back that putting dual parity into the system wasn't as big a win for existing customers as working towards mitigating the need for rebuilds all together. Hence the reason it appears now instead of a release or two ago.
Assuming someone doesn't introduce RAID-thing-a-me-bob the focus is going to be on mitigating the need for rebuilds and not adding octuple parity to RAID. But again that plan will probably change depending on what customers ask for.
Asymmetric Logical Unit Access, or poor man's Active/Active as I tend to call it, is not true Active/Active in the Symmetrix use of the term but it is in the mid-range use of the term. Technically that makes sense even if in English it may not. Regardless, in single path environments if you suffer a failure it removes an SP trespass from disrupting front end IO traffic. If you need "true" Active/Active and you're looking at a CX3-80 you're within range of a DMX-4 950, but for those people who aren't or don't need a Symm ALUA is a great step forward in path availability, and it integrates with a lot of host based path management tools.
Probably technically the least interesting but important to highlight none the less. EMC doesn't care what the transport is, that's why the company has added iSCSI as a transport option to it's array based replication technologies in it's dual-protocol systems. While there might be an FC/iSCSI war going on out there somewhere the company will continue to chase the money regardless of what protocol that money is in.
Want to use MirrorView or SAN Copy over iSCSI? Go for it.
In order to play in a lot of accounts these days you need a credible security story, EMC's story is starting to shape up with the introduction of RSA technology into the platforms. It started with Symmetrix Credential and now it moves down stream into Clariion with features such as Security Administration roles, Audit Logs and Secure Administration.
There could have been a security specific release of FLARE but doing a big bang security introduction is an awful idea as misconfiguration can be deadly. As releases progress you'll see more and more security functionality become visible but it's a step by step process.
There's a lot more in there but thats something for your reading pleasure. They're called release notes and they go nicely with a cup of something warm.
So what's missing? Well Thin Provisioning of course. Lets not insult each others intelligence on that one. You know the question, by now you know the dodge I'll use to avoid answering the question, but we both know how it'll all turn out.
Moving on to Centera.
It's a simple equation.
50% capacity increase with a 67% power utilization decrease per TB per node
That's the Gen 4 LP node announcement in a nutshell. While tech optimism can sometimes blind us to the overwhelming nature of some problems "If we can put a man on the moon surely..", optimism is what gets us through some others. You've every big brain in the industry working to squeeze energy efficiency out of every single hardware component in development or just hitting the market, all of that adds up to big savings and since you can just drop these into existing Centera clusters you can realize those savings immediately.
CentraStar also receives numerous performance and functionality updates, the usual suspects such as enhanced logging (There's that security thing again), enhanced disk management (There's that rebuild mitigation thing again), and enhanced reclamation operations. They've also starting adding what was previously API only functionality to the CIFS/NFS/FTP/HTTP Centera Universal Access (CUA) software so you don't have to use the API.
The NS-20 is the new entry level model. It's physically smaller, can be set up in less than 15 minutes, is built on the CX3 architecture, offers greater capacity, is multi-protocol (NAS/iSCSI/FC) and performs faster than it's predecessor all while having a ton of advanced functionality thrown in for free.
Other vendors used to do a good job of selling the "EMC is too complex" story. They were right at the time but that's no longer true today. Previously a Celerra would show up and who knows how many people would be involved in getting it up and running. Not the technology but the blizzard of paper work required before anyone could lift a finger. Today it's less paper and a few clicks of a mouse. Message received. Complexity removed. The future has arrived.
The new file management appliance is an entry level unit shipping with the Rainfinity File Management module installed. You can read my Rainfinity post here for further details on the larger product set but you should be aware that this entry level product can manage a couple of hundred million files, the clustering ability is still there, and the data sources can be EMC Celerra or NetApp Filers with targets being Celerra, Centera, and NetApp.
If you're a NetApp or Celerra shop give it a look, it's a nifty product and what running the Data Collector alone against your NAS file systems will tell you about what you could gain by archiving is insightful .
Right, so that's what I digested from today's announcements more information is most certainly going to come to light and watch the skies for Barry's view of DMX-4 from the inside out.
