Symmetrix, Celerra, Centerra, Oh My!

For the last few weeks I’ve been on the periphery of an engagement.  Disk Extender.  Not one of my favorite products but in the interests of full disclosure I have only seen it from the outside, in.

When I was working for the fake non-profit a while back, we were evaluating long-term storage.  You know, the kind of thing a bank or lending institution would need to keep documentation required by the federal government.

We evaluated the usual suspects, Centerra/DX-UL, NetApp Compliance, etc.

I’m not going to tell you which one I selected, because that’s not the actual topic of this post.  But the Centerra as a stand-alone device was NOT in contention because we needed to be able to drop flat-file information from various applications not Centerra-aware.

I have a suggestion for EMC.

Take the celerra, integrate the Centerra API and use it as a gateway to the Centerra.  The Celerra takes the file, passes it to the Centerra via the API and allows read access like it was a “normal” share.

If you wanted to get even more creative, you could incorporate the (I can’t believe I’m suggesting this) Avalon code into it to allow for a totally intelligent tiered-storage architecture.

(not that I have any positive things to say about my experience with Avalon – wasn’t an easy install)

    Celerra File Mover (Included since DART 5.3) but you need a policy engine like Rainfinity FMA if you want to put rules around the data movement. It’s the Celerra which does all the migration to the other storage tiers.

    If you just want NAS for Centera that’s what Centera Universal Access is for. Flat file CIFS/NFS/HTTP/FTP access.

  1. So I am woefully uninformed is what you’re saying. (don’t worry, part of life as a partner is missing the new product/feature announcements – I don’t get to see what’s out there until I install it.)

    So if Centerra Universal Access is available, why aren’t they pushing it? Why is DX still the main passthrough? The only reason I can think of is that DX might be either a higher-dollar or higher margin product… But sales people wouldn’t DARE push the wrong product just because it makes their bottom line look better, would they?

    The problem I see with DX is that you’re still creating a choke-point for your data. You may have the biggest, fastest Centerra in the world, but if all of your IO has to go through one server, that server becomes your weakest link.

    My question for you then is – what does DX do that CUA doesn’t, and vice versa.
