Optimizing Data Retention and Archiving

As we wrap up the year, people's thoughts turn to archive anddata retention.

The [Robert Frances Group] have put out a research paper titled Optimizing Data Retention and Archiving - November 2007 that helps IT executives understand the cost differences for a disk-only archive approach versus disk/tape archive approach and how an [IBM System Storage DR550] offering can help address the long-term storage archive requirements with a world-class storage strategy that reduces cost, improves efficiency and supports compliance. Here is an excerpt:

Ongoing legal, audit, and regulatory requirementswill continue to drive IT groups to improvearchive policies, processes, strategy, andefficiency. The choice of which technologies touse will have a profound impact on the success ofsuch efforts, since technologies like the DR550embody many aspects of the strategy, processes,and policies that must be decided upon. When itcomes to tape, IBM's DR550 is unique inproviding that support. Competitors tout disk-onlysolutions as the wave of the future, but researchindicates otherwise. The most basic benefits arecost and mobility, and despite the various vendorproclamations to the contrary, tape is still only afraction of the cost of disk and will remain so inthe foreseeable future.

This paper is yet another nail in the coffin of EMC Centera.In his post [Anyone Naughty on Your List…], Jon W Toigo points to an eBay fire sale of an EMC Centera Gen 4.

There has never been a better time to switch from EMC Centera to theIBM System Storage DR550.

Guys,
I found the Centera ad amusing when it was forwarded to me by a reader. I found it even more amusing when a customer was ditching one without opening the box.
Storagezilla's and Storage Anarchist's ad hominem attacks aside (always a clue that they have no valid argument to make), I agree that there are a lot of reasons why products would appear on the grey market. My good friends at ASCDI make their livings off of selling used gear, which they will re-certify and maintain even if the vendor chooses not to.
The key point that I continue to make about Centera is that it manifests significant flaws that EMC chooses not to address publicly. Don't take my word for it. Check out posts by Hal Weiss from Baptist Memorial Healthcare or have a chat with Paul Carpentier, formerly of EMC-acquired FilePool and intimately involved with the development of the core technology behind Centera, and they can explain the product's many many foibles.
I am hoping that the eBay ad is a sign that folks are finally questioning the efficacy of the product, which provides an open API for ingesting data, but presents a closed API for un-ingesting the data from the box. EMC showed me this product before releasing it and clearly stated that they wanted to use it to own the customer by owning his data.
If it makes me Anne Coulter to believe that this is not in the best interests of the consumer, then I guess I need to change my political stripes and grow some blonde hair.

BarryB (storage anarchist),I don't know Jon Toigo personally, but I enjoy his blog writings. Since the Robert Francis Group specifically compared DR550 disk-and-tape solution to disk-only alternatives, it was relevant to mention EMC Centera, which is a disk-only alternative.
Your merger theory doesn't make sense. Since when does a merger allow a company to discard its corporate data prior to the merger? If the company felt it was important enough to keep prior to the merger, wouldn't it still need to keep it after the merger, until the expiration is met? I am not a lawyer, but I can't think of any data that could be discarded so readily.
The only way a merger would apply is if the EMC Centera in question was empty. I have met a customer that had one for six months, and still no data stored on it. They bought it because they thought it was a good idea at the time, but did not actually store anything on it.
And if recent August/September announcements of the latest upgrades to Centera is your proof that it is still alive, then IBM's October announcements for DS8000 should qualify as proof that IBM is still investing in our high-end disk.
The ability for DR550 support for a blended disk-and-tape solution is something that EMC Centera has not yet delivered.

Aligning yourself with Jon TwoEgos drops your credibility rating significantly, Tony. Your choice, but it wouldn't be mine.
But you just keep on believing that Centera is dead, even as it continues to gain market share as the most comprehensive active archive solution on the planet, pretty much without any competition even after 5+ years in the market.
And unlike your own DS6000 and DS8000, which you clearly have ceased investing in, the Centera product lineup continues to be enhanced and to grow, with new capabilities (and more power efficient nodes) announced and delivered just this past August/September.
Mergers often beget orphaned capital equipment (and people too, unfortunately). Here's hoping that the E-Bay Centera finds a good home, undoubtedly alongside several of its brothers and sisters, protecting some other company's digital assets.
