A storage area network coupled with disk-based backup slashes backup-and-restore times while minimizing manual tasks.
News Analysis Trends
This year, vendors are expected to make significant strides in merging network-attached storage (NAS) and storage area network (SAN) environments, according to a recent report on network storage by the Yankee Group, a market research firm in Boston.
This month, EMC added software enhancements to its Clariion FC4700, pushing the midrange storage array's functionality closer to that of EMC's flagship Symmetrix array. The software upgrades consolidate management and enable better disaster recovery.
Just six months after acquiring StorageApps, a provider of storage virtualization software, for $350 million, Hewlett-Packard earlier this month formally announced its virtualization strategy and a new midrange virtualization appliance: the StorageApps sv3000.
At Storage Networking World earlier this month, Integrix spin-off iQstor Networks debuted a family of integrated storage systems that scale from 8TB to 35TB. Initial hardware offerings include two disk systems (R1900 and J1800) and a "SAN-in-a-box" (iQSAN).
Legato Systems says its planned acquisition of OTG Software, a developer of data storage, data access, and e-mail management software, will result in tangible benefits for end users as early as this quarter.
Fibre Channel switch vendors now offer a variety of lower-priced, lower-port-count devices for small to mid-sized companies. For example, end users can now buy 8-port, 2Gbps Fibre Channel switches for as little as $5,000, or $625 per port.
Quantum last month added its name to the growing list of vendors that offer disk-based systems specifically for backup. Quantum, which dominates the midrange tape drive market, says it will ship its first disk-based system—the DX30—in the second half of the year.
In the first year that OEMs shipped network-attached storage (NAS) devices based on the Microsoft Windows platform, they grabbed a 25% market share based on units shipped (through the third quarter of 2001), according to International Data Corp.
Distributed storage located at the "edges" of the Internet can help service providers overcome two of the key drawbacks to the Internet: bandwidth and latency.
Using an analyzer for SAN troubleshooting can uncover hidden problems and unlock full performance potential.
Emerging technologies, coupled with virtualization, will blur the distinction between NAS and SAN, leading to a convergence in storage networking.
This article, the first in a two-part series, looks at the requirements for transporting Fibre Channel SAN traffic over managed IP networks.
Some of the hot technologies include iSCSI and IP SANs, storage virtualization, new backup options, and disaster recovery.
Facing impending competition, Fibre Channel supporters cite improved interoperability, faster performance, and lower prices.
It should come as no shock that, according to virtually every survey of end users, "high cost" is the number one reason why users have not implemented a storage area network (SAN). Fortunately, however, the Fibre Channel vendor community has recognized this and is doing something about it.

We have a number of small, independent, departmental storage area networks (SANs), which we back up to a centralized LAN backup system. We want to leverage the SAN for backup but cannot afford to—nor do we really want to—consolidate our individual SANs into a single, larger one. Do we have any options?
"Storage virtualization" is too broad a term for practical use. You have to look closer at specific implementations and features.
Three of the latest Linux journaling file systems show their merits on a fast RAID appliance from Adaptec.
In the future, virtualization will encompass disk drives as well as tape and optical devices.
