(Rob Young) wrote in message ... It is a niche. It requires tying into an API. In a few years, I suspect various solutions won't require API tie-in and so many of these products today will be flash in the pans. Hi Rob- I just wanted to clarify one of your points. Not all CAS-based storage solutions require the use of an API. For instance Centera exposes a file system via an application gateway. Yep - you can front-end it with something. Rube Goldberg. But if all of 100 apps tie into the API, how else to sell such a solution other than a gateway? So what path is that? HBA to switch to gateway to CAS appliance? "Still much faster than tape!" Puffs the salesman. Question: "What filesystems?" http://searchstorage.techtarget.com/...954844,00.html Most major document management software providers have already integrated their applications with Centera by writing to its API. EMC claims to have recruited more than 300 Centera partners and resellers and offers 100 integrated applications. But many legacy and homegrown applications have not been -- and never will be -- ported to Centera. Enter Storigen Systems. Storigen's Centera Application Gateway (CAG) lets users hook their existing fixed-content management applications into EMC's Centera CAS system. The gateway speaks CIFS and NFS on one side and Centera's language on the other, which allows users to manage both new and legacy fixed-content applications under one umbrella. --- NFS and CIFS. My - that's handy! There are also HSM/ILM based solutions that expose Centera as a file system. And, aside from Centera, Permabit offers a full software only CAS solution that is completely file based, with no API. Yeah - HSM has been around for a while now. It is hard to imagine that the technology will become a "flash in the pan". Sure - when the need for an API goes away and you aren't tied into a storage vendor - that is the way to go. All this supposed intelligence is/will make its way into the switches - probably where it belongs. Elsewise, you end up building a Rube Goldberg contraption and narrow your filesystem choices. Compliance regulations are only getting stricter as we move forward. When a financial institution is required to save all of their emails for 7+ years and be able to deliver/authenticate them on a moments notice, then a CAS-based product really becomes the ideal solution. Otherwise which company out there wants to save 100+ individual copies of the same 2 MB attachment for 7+ years? No one. Modern email systems don't work that way. BLOCKS that haven't been touched in a while need to migrate to cheap storage automatically. If they suddenly become hot again, they should automatically migrate to faster storage. Additional infrastructure and management doesn't appear the way to go. The infrastructure and management should be in the switches. The switch provisions VLUNs. The LUN is made up of differing types of storage. And yes - it may take a while to get it right but it would be an ideal way to go in my opinion as its greatest advantage is transparency. Filesystem and database transparency. Rob |

No one. Modern email systems don't work that way. Hmmm...The SEC just announced that they will be archiving their email to a Centera. Modern email systems single-instance live content. A Centera based email archiving solution single-instances all known content. http://biz.yahoo.com/prnews/040415/neth011_1.html The SEC's Office of Information Technology had an initiative in place to meet the following business objectives for thousands of mailboxes in an Exchange environment: Reduce the growing size of the Exchange messaging databases by efficiently migrating mail off the message servers to specialized and more affordable online archive storage. Improve email archive search capabilities to enable ready access to and production of email files as needed. Also AT&T recently announced that they are basing their email archiviing service on Centera. http://searchstorage.techtarget.com/...958553,00.html Looks like the flash in the pan is getting brighter and brighter :-) You can learn more about Centera and CAS-based solutions at the Centera Tech Group on Yahoo! http://groups.yahoo.com/group/CenteraTechGroup/ Thanks!

(Rob Young) wrote in message ...
The modern email system remark has to do with your earlier comment about "instead of keeping 200 copies you have one." Rob, the point that I was trying to make is that there is a difference between an email system and an email archiving system. Email systems typically manage active email data, where an email archiving system can manage several years or decades worth of email and attachments. You are correct that email systems have single-instance storage built in. However when the data is archived to optical/tape multiple copies of single-instance data can occur when the same document is archived on multiple occasions (e.g.; a resume, x-ray, or some other attachment). The difference is that email archiving solutions that migrate content to a CAS appliance will be able to take advantage of single instance storage whether 10 copies of the same document were stored in 1-day, or continuously over a 5 or 10 year period. Sure - now they are up to 101 applications. Not necessarily. AT&T is offering an existing KVS CAS solution, and the SEC is going with an existing EmailXtender CAS solution.

If your archiving system retains multiple copies of an object then you will of course have multiple copies of that object. If you don't want the redundancy then don't save multiple copies of the same object. That way you save storage at the cost of reliability. But this doesn't require CAS, it just requires a backup or HSM system that follows the policy you're interested in. -- I've seen things you people can't imagine. Chimneysweeps on fire over the roofs of London. I've watched kite-strings glitter in the sun at Hyde Park Gate.
