Access "Hashing Makes a Comeback"
This article is part of the Vol. 3 No. 2 April 2004 issue of Storage managers give thumbs up to IP storage
In the mainframe's heyday, disk was expensive, prompting systems vendors to use hashing algorithms to trim down their data stores. By transforming a string of characters into a shorter fixed-length value that represents the original string, hashing can ensure that a character string is only stored once. These days, storage is cheap, but data is plentiful, so storage vendors have once again turned to hashing to keep data capacities under control. The best-known example of this trend is EMC's archive solution, Centera, but several innovative startups have also resurrected the hash. Avamar uses a hash function to reduce the amount of data it stores in its Axion backup and recovery arrays, while Permabit uses it as the foundation of a software-based compliance repository. But Marc Duvoisin, national director of enterprise servers and storage for Dimension Data, in Reston, VA, thinks hashing's real promise lies in remote office consolidation. "Networking has gotten cheaper, but not that cheap," he says. And as of yet, no one has solved the problem of ... Access >>>

Hashing Makes a Comeback
Hashing is back
IP storage delivers
by Johanna Ambrosio
Despite all the FUD surrounding IP SANs, early users say IP-based storage isn't all that difficult to manage and that performance is sufficient. The key is knowing what applications IP SANs should be used for.
Wrestling with regulations
by Bill O'Brien
In the health care industry, complicated regulations such as HIPAA, combined with new technologies that require enormous amounts of storage, are driving storage managers to the emergency room.
Get control of capacity
Although storage resource management tools can be complicated to implement, they're a better alternative to breaking the bank and rushing out to purchase more storage. Get precise with your vendors on what you need and you'll wind up with better results.

E-mail Management Derailed By Regulations
Everyone wants a say in e-mail management.
Disaster recovery relief
The cost of disaster recovery tools can be even more than the value of the data that these very tools are supposed to be protecting. Fortunately, newer approaches to DR are restoring sanity to this high-pressure task.
