Access "New tools trim primary data"
This article is part of the Vol. 6 No. 2 April 2007 issue of Backup overhaul: From a mainframe to an open-systems environment
One of the hottest storage topics these days is data deduplication, a broad term that includes several technologies such as single-instance storage and commonality factoring. While it can trim data capacities significantly and forestall buying more disk, deduplication has always been the exclusive province of nearline storage, most often used in conjunction with data protection applications such as archiving. But few dedupe vendors have tried to apply their techniques to primary storage largely because of the impact on performance. A couple of pioneering vendors hope to change this. Storewiz recently rolled out the next generation of its primary storage compression appliance, which has been available for more than a year. FalconStor Software has a similar compression product on the drawing board. "We are expecting this special-purpose computing module to be available in [the] late 2007, early 2008 timeframe," notes ReiJane Huai, FalconStor's chairman and CEO. The two companies are taking somewhat different routes, but the goal is the same--to put the squeeze... Access >>>

Unsnarl port traffic
Configuring the number of ports on storage arrays and switches shouldn't be a guessing game that results in an excess of ports and a big dent in your budget. To properly size a switch or storage array, you need to analyze the average and peak bandwidth requirements of each device. Monitoring current utilization rates will help you determine effective bandwidth requirements.
New connections: SAS and iSCSI HBAs
Serial-attached SCSI and iSCSI host bus adapters (HBAs) represent the latest in server-to-storage connectivity technologies. Tailored to specifically address the needs of two emerging storage protocols, these new HBAs can ensure that performance isn't sacrificed when one of these alternatives to Fibre Channel storage is deployed.
Free up database space
Database archiving is critical to the long-term management of an enterprise resource planning (ERP) application. Archiving can shorten backup windows, speed recoveries and improve the database's overall performance. But effective archiving means carefully selecting the data to be removed from the production application and moved to secondary storage, and ensuring that it remains available and adequately protected.
Storage Bin: Duplessie's theory of evolution
Evolutionary changes in the storage world have opened the door to scores of smaller companies. Some of these startups have seized the opportunity, taking advantage of the current market dynamics. Good for them; but it's even better for you, with more choice and innovation than we've seen in a long time.
Hot Spots: Remote workers, stand up and be counted
Remote-office workers need to share their experiences with corporate IT because there are many different issues associated with working remotely and a wide range of products to address those problems.
Best Practices: Balance workloads with RAID types
Vendors will tell you how beautifully parity-based RAID works in their storage subsystems, making it almost unnecessary to use any type of striped/mirrored RAID protection. But if you don't match the workload profile of the application to how storage is provisioned in the array, you could wind up with a poorly balanced system.
