ISCSI growth on the rise

Lower costs and simplified management are driving enterprises to iSCSI technology

iSCSI technology is entering the mainstream as growing numbers of enterprises consider the storage alternative for its lower costs and management simplicity, analysts say.

The technology lets blocks of storage data be transported over Gigabit Ethernet and is easier and less expensive to install than Fibre Channel. Because it runs over Gigabit Ethernet networks, iSCSI doesn't require host bus adapters in servers and Fibre Channel switches. Nor do IT administrators, for the most part, need to have special knowledge and training in storage technology to deploy iSCSI.

According to IDC, while iSCSI today accounts for only a 3 percent share of external disk storage, the research firm expects it to reach more than 20 percent by 2010.

Enterprise Strategy Group (ESG) says that more than 20,000 customers have deployed iSCSI. The research firm surveyed 500 IT managers and found that 17 percent are using iSCSI in production environments and an additional 20 percent plan to implement the technology.

Lower costs and iSCSI's ease of management are among the factors driving adoption -- and not only among small and midsize businesses. Nearly 20 percent of businesses with 20,000 or more employees have deployed iSCSI, ESG reports.

Meanwhile, as shipments of iSCSI storage products have started climbing, start-ups specializing in iSCSI have emerged, such as Sanrad, LeftHand Networks, Intransa and EqualLogic.

EqualLogic, by its last count, has more than 2000 customers. EMC, meanwhile, added iSCSI capability to its midrange Clariion arrays and to its high-end Symmetrix DMX storage systems. Network Appliance, the leader in network-attached storage systems, has logged more than 30 percent market share for iSCSI systems shipped in 2006, according to IDC.

For its part, Sanrad claims more than 600 customers are using its iSCSI technology, and this week the vendor introduced a midrange iSCSI switch. Sanrad's V-Switch 3400 is a 3-port iSCSI switch with four Fibre Channel ports. The V-Switch has dual hot swappable power supplies and is managed via SNMP, a graphical interface and a command-line interface. It supports as much as four P-bytes of storage capacity and starts at US$26,000.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
