Access "Storage Bin: Duplessie's theory of evolution"
This article is part of the Vol. 6 No. 2 April 2007 issue of Backup overhaul: From a mainframe to an open-systems environment
Darwinian forces are at work in the storage industry, and users stand to benefit the most. Last month, I explained why the storage business works the way it does. This month, I'll talk about who's benefiting from the evolutionary changes that have occurred in this space. Revolutionary events cause rifts in the atmosphere, creating holes of new opportunity. IBM caused the great computer rift--enabling machines to perform business tasks--and it propelled them to historic levels of greatness not seen since the industrial revolution. The firm's success caused slower, evolutionary changes that enabled new holes of opportunity. Apple did it with iPod. Microsoft did it. But as IBM became more successful, the forces of evolution took hold and the problem shifted from "How do we get more leverage out of our high-priced math-whiz actuaries?" to "How will we keep all this electronic gadgetry up and running?" to "How do we do much more with way less?". Enter EMC, a fledgling memory company that saw an opportunity with a cheaper, faster, better play--namely storage. This... 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.
