Here are five ways to achieve heterogeneous host attachment across storage area networks, with advantages and disadvantages.
Over the past year, storage area network (SAN) technology has made significant headway. While the primary impetus behind SAN technology has been increased connectivity and bandwidth from servers to storage devices, new options in the form of adding intelligence to SANs to solve enterprise-wide storage management problems are becoming possible. This article introduces the notion of "intelligent" SANs, specifically what forms of intelligence can be embedded in SANs and how this technology may solv
Converting 3D digital images into film, video, or CD-ROM format is a computationally-intensive process, in some cases requiring several hundred gigaflops (or one billion floating points per second) of total computational power. With data demands like this, network bottlenecks are common.
In the first of a two-part series, we examine the advantages and disadvantages of various backup techniques.
Users are demanding greater data management from their storage subsystems. In response, subsystems (RAID for example) are taking on more functionality and suppliers are attempting to increase profit margins by adding value to their products. The result of this trend: Network-attached storage (NAS) is becoming an increasingly important technology to increase functionality and potentially lower initial purchase and management costs.
Enhancements such as Ultra2 SCSI, expanders, LUN bridges, switches, and Ultra3 SCSI promise to expand the life of the venerable interface.
Iomega is king of the hill, but there are a number of existing and emerging alternatives for desktop removable storage.
Array View II from Aiwa RAID Technology is software designed to support remote monitoring capabilities over the Internet using TCP/IP. Designed to work with the company`s MicroArray III disk arrays, the software enables array monitoring over a variety of network topologies.
Last month, Artecon introduced a Fibre Channel RAID array with dual-active controllers and dual-redundant data paths. If one controller or data path fails, system traffic is automatically shifted to the remaining controller or path. The SuperFlex 7000FC can deliver a maximum aggregate throughput of up to 200MBps and comes with Artecon`s Redundant Data Path (RDP) software and RAIDScape management software. The arrays can be equipped with up to 256MB of controller cache and 10,000rpm disk drives,
Artecon`s RDP (Redundant Data Path) for NT software is designed to increase the performance and reliability of RAID subsystems with dual-active controllers. In the event of a system component failure, RDP creates an alternate data path between the server and the RAID array. The result: the I/O path is no longer a single point of failure. RDP for NT is available as an option for Artecon`s SCSI-to-SCSI dual-active controller RAID systems. Pricing for a single-server license is $3,800. www.artecon.
Axis Communications` StorPoint Disco software facilitates access to CDs and DVDs networked by StorPoint CD servers. By networking CDs and DVDs in one user desktop folder, users do not need to know the location or name of a particular server to find a CD. As a result, in an environment with hundreds of CDs and several networked CD towers, data can be accessed faster. StorPoint Disco automatically searches the network for Axis-based CD servers from tower manufacturers such as Boffin, Meridian Data

If you`ve caught Fibre Channel fever, as we have, you may want to head out to San Jose next month for the first annual Fibre Channel Technologies Conference. See our News section for a preview or go to www.fibreconference.com. They`re promising almost 100 speakers, more than 30 exhibits, and sessions and tutorials on virtually every aspect of the emerging interface.
With storage management widely viewed as one of the largest IT expenditures, administrators are continuing to turn to storage management software as one way to corral these costs. The need to centralize resources has fueled steady growth in storage management software, according to a recent report from Dataquest, a market research firm in San Jose.
Compaq`s acquisition of Digital Equipment Corp. will bump IBM from its position as the world`s largest vendor of storage systems. According to International Data Corp., a market research firm in Framingham, MA, Compaq and Digital had combined storage revenues of more than $4.9 billion last year.
It`s no secret that multiple standards have long been a gating factor holding back a potential industry from blooming. For OEMs, VARs, and end-users looking to use today`s DVD technology, they first must wade through an acronym soup of divergent formats before they can spell out what will work best for their application. For that and other reasons, industry analysts such as Dataquest`s Mary Bourdon believe full-scale DVD implementation is still a few years away.
While still an emerging technology in terms of actual implementation, Fibre Channel awareness within the storage industry is running high. While Fibre Channel`s ability to support multiple protocols and longer cabling distances are important assets, everybody wants to talk about its speed. After all, this storage/network interconnect can provide data transfer rates of 100MBps, right?
