IBM is adding features and capacity to its entry-level disk storage array products for small to midsize businesses (SMBs) to match that of more expensive enterprise-level systems.An industry analyst says IBM, along with its competitors, is offering improved storage capability, easier-to-use management software and lower prices to smaller businesses that need more storage but may not be as technology savvy as larger companies.IBM Tuesday is introducing the DS3000 series disk array line to replace the DS300 and DS400 models. The new series comes in two models, the DS3200 (starting list price: US$4,495) and the DS3400 (US$6,495).The DS3200 uses the small computer system interface (SCSI) connectivity standard, moves data at up to 3Gbps and has a maximum of 14.4\u00a0terabytes of storage capacity on its 12 disk drives.The DS3400 uses the Fibre Channel connectivity standard and moves data at up to 4Gbps. It also has 14.4 terabytes of storage capacity on 12 disk drives. Both models are designed to work in IBM System x servers and some other server brands.Both run IBM\u2019s Storage Manager software, which allows customers to set up the devices on their networks in six easy steps."And the first step is, \u2018Take it out of the box,\u2019 " said Alex Yost, director of product management for IBM System x. "It\u2019s really easy. Some folks get these up and running in less than an hour."Setup and ongoing management of storage arrays is important for small to midsize businesses\u00a0that have growing storage needs but perhaps not the in-house expertise to know how to operate the equipment, said Dianne McAdam, a storage industry analyst at The Clipper Group.IBM and other storage vendors, such as EMC or Hewlett-Packard, are now offering features for the SMB market that were previously available only on high-priced models sold to larger enterprises, McAdam said."The [storage arrays] are getting very advanced and sophisticated, but at the same time they are getting easier to use because they have this nice interface. With a couple of mouse clicks, you can create a copy of a storage volume. Boom, you\u2019re done," she said.The pricing could motivate SMBs to replace outdated storage appliances."Some of these smaller customers have older equipment; they don\u2019t want to move off of it because at least it\u2019s working," McAdam said. "The way you can move them to the newer stuff, which is faster, better and cheaper, is to provide these management interfaces that are just so darn easy to use."-Robert Mullins, IDG News Service (San Francisco Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
