Bank Invests In Dedupe To Shrink Backup Windows
If time is money, then First National Bank of Pennsylvania was spending way too much to back up critical applications. A full weekly backup would take 90 hours, and nightly incremental backups were taking around 24 hours. The bank, which has over 220 branches in PA and Ohio, was also bogged down with a tangle of products: 13 different backup systems were employed to service 570 servers. The company had to devote an IT staff person full time just to maintain all these backup products. When the bank decided to migrate from direct-attached storage to a SAN, it also decided to streamline its backup operations and embrace deduplication.

Rapid Backup And Retrieval With Riverbed's Whitewater
Cloud storage brings cost effective offsite backup and retrieval capabilities to small and midsize businesses, but using cloud storage as an external disk is not as effective as it seems, particularly as the data set grows. It takes time to send and retrieve files to a cloud storage provider and often means using another set of tools to do so. Riverbed's Whitewater appliance makes the cloud storage appear as a backup target and balances the competing needs of speedy read/writes and long-term bulk storage. Using a combination of local file caching and deduplication with cloud storage replication, IT gets the best of both worlds.

The Promise of LTFS
April 05, 2012 09:00 AM
Posted by Howard Marks
A bit more than a year ago the folks behind the LTO tape format standards, primarily IBM, with some contributions from HP and Quantum, added the Linear Tape File System to LTO's feature list. While some niche markets, primarily the media and entertainment business, have adopted LTFS, it won't live up to it's promise without support from archiving and eDiscovery vendors.

A Rose May Be A Rose But Dedupe Is Not Necessarily Dedupe

Today just about every vendor in the storage market has data deduplication as a feature in one or more of their products. While those of us that work with multiple deduplication products on a regular basis know there are big differences between the various technologies that vendors call data deduplication many users don’t know how to pick the deduplication solution that will best fit their needs.

Nimbus Sets The Stage For Mainstream Enterprise SSD
February 13, 2012 09:00 AM
Posted by Howard Marks
Solid-state array pioneer Nimbus Data's new E-Class array system is a sign that solid-state storage is moving from the high-performance fringe to the mainstream of the enterprise data center. Most first-generation, all-solid-state arrays, including Nimbus Data's own S-class, were best suited to targeted applications where high performance with single points of failure was acceptable. The new asset class, like most midrange disk arrays, has a dual-controller design to satisfy my enterprise reliability requirements.

HP Storage Tech Day

Last week I joined a dozen or so fellow bloggers and storage industry gadflies for a storage field day at HP's Fort Collins, Colo., facility. Much like the more ecumenical Gestalt IT Tech Field Days run by our own Stephen Foskett, HP Tech Days let vendors show off their shiny new products while the street-wise delegates asked tough questions and took no marketing speak for an answer.

Dell Moves Ahead Fluidly in Storage
January 20, 2012 12:32 PM
Posted by David Hill
The IT industry is always adapting to new trends, from client-server and the PC revolution of the '80s and '90s to cloud computing and big data today. These trends inspire successful new vendor entrants, but they can also be problematic for established IT vendors. Over time, some leaders don't adapt and die (see Digital Equipment Corporation), while others swoon and survive in a reduced state by being acquired by larger saviors (see Sun Microsystems).
