Last month, EMC launched its Control-Center framework to address storage resource management (SRM) across Symmetrix disk arrays and storage network components from a variety of vendors.
Last month, Hewlett-Packard discontinued production of its 3GB DVD+RW drive, culminating a year of overall stagnation in the rewritable DVD optical drive market. Citing a lack of market demand, HP will instead focus on delivering a 4.7GB model, but would not commit to a ship date. In June, HP announced plans to ship the 3GB model by the fall.
Tackling the daunting task of testing customers` storage area network (SAN) configurations, IBM is building two large labs in the U.S. and Europe. The facilities engage in performance and stress testing, as well as interoperability testing. The U.S. lab, which opened in August, is based in Gaithersburg, MD, at the company`s 80,000-square-foot National Testing Center.
Not surprisingly, EMC will top the list of external RAID vendors this year, ranked by projected revenues. In fact, EMC is expected to garner more than 26% (over $4 billion) of the total market ($15.4 billion), double the 12.9% market share for Compaq and 10.6% for IBM. According to IDC`s 1999 Worldwide Disk Systems Market Forecast and Review, here are the expected rankings and revenues (external RAID only):
Over the past several weeks, Linear Tape-Open (LTO) drive manufacturers Hewlett-Packard, IBM, and Seagate have engaged in a series of cat-and-mouse maneuvers in an attempt to position themselves for a piece of the midrange tape market, currently dominated by DLT. The three vendors expect to ship LTO drives in the Ultrium format by the middle of the year, while Fujitsu—the fourth and comparatively quiet LTO drive provider—is targeting October for product delivery. Quantum, meanwhile, re
Disk array shipments are continuing a decade-long trend of steady growth, fueled by the commoditization of RAID technology and a continuing thirst for storage in open-systems environments.
While continuing to develop standards, the Storage Networking Industry Association (SNIA) recently stepped up its efforts to involve end users. "We`re forming a customer advisory council to bring the IT community into SNIA and advise us on what we should be focusing on," says Larry Kranz, newly-elected SNIA chairman. "Our focus has changed from vendor-oriented to IT-oriented."
Formed about a year ago as a storage integrator, WorldStor is now beginning to enter the potentially lucrative, yet nascent, storage outsourcing market. At press time, the company was completing its first round of financing.
The increasing complexity of storage environments, 24x7 data access demands, and the emergence of storage area networks (SANs) are among the top reasons for companies to consider storage outsourcing, according to recent reports.
Once thought to have fallen short in terms of capacity and performance, tape storage has come back strongly. A crop of high-capacity, high-performance drives will soon be available, offering 100GB of uncompressed capacity with data rates in excess of 10MBps. These drives are expected to catalyze the tape automation market, poising it for a renaissance next year.

One of the leading Fibre Channel component vendors recently released to the press and prospective customers a comparison test, performed by an "independent" third-party test outfit, that compared its products to two of its competitors` (I won`t mention the vendor or testing outfit because I don`t want to call attention to the study, for the reasons outlined below.)
News Analysis Trends
Demands on data are increasing rapidly, in large part due to audio, graphics, Internet, and e-mail applications. Protecting these assets is critical, and ready access to data is imperative. But storage is also a performance element of information technology, not just a repository for data, images, and audio files. One approach to protecting data while maximizing performance is to centralize your storage resources.
Reality check: Fibre Channel is here to stay, but it`s far from perfect. Users face a variety of choices to meet a variety of economic and technological challenges, and there`s no guarantee that two Fibre Channel products will be compatible. As a result, end users often rely on third-party integrators to evaluate, test, qualify, and integrate the components that are sold as overall solutions.
There`s been so much press and vendor news surrounding storage area network (SAN) architectures, products, and strategies, it`s easy to lose track of host-based RAID, still the most dominant method of storage attachment. SAN technology is exciting, but the publicity has overshadowed progress in PCI-based RAID.
Controller-based data caching can double or triple I/O performance, but "your mileage may vary" depending on the access patterns of your applications. Aside from corner-case applications like video broadcasting, caching can significantly increase I/O performance. But by how much and at what risks? This article explores the data reliability question.
As servers become more powerful and memory cheaper and more plentiful, software RAID with its multiple processors and gigabytes of RAM can help cut costs, or can it? For some simple data striping or mirroring applications involving only a couple of hard drives, it may very well be the best choice. But for very large volumes of disk space and extremely rapid file transfer, intelligent RAID controllers are the best answer.
A look at the technology and business trends that shaped the storage market in 1999, and what to expect in 2000.
