Adaptec exits Fibre Channel market
In a continuing effort to reduce operating costs, Adaptec Corp. last quarter announced several cost-cutting measures, including the discontinuation and sale of its Fibre Channel assets.
SAN Management: The Basics
Storage area networks (SANs) represent a fundamental shift in the way distributed computing environments relate to storage resources--a shift that has important ramifications for the way storage is managed. This article examines how data protection can be managed in a SAN today. Next month, we`ll examine the potential of improving the management and protection of storage with SANs.
nStor adds NAS to RAID
nStor Corp. recently began shipments of the thinStor 300, a network-attached storage (NAS) option for its CR8e and CR8j RAID subsystems.

This month, Procom Technology began shipments of a network-attached RAID subsystem that in some configurations will cost about 13 cents per MB, based on expected street pricing. Procom sells primarily through resellers and distributors.
Quantum first to announce Ultra160/m drives
With the announcement last month of its Atlas 10K and IV disk drives, Quantum became the first drive manufacturer to preview products that support the new Ultra160/m specification. Quantum expects to ship volume units of Atlas IV in the first quarter of 1999; full-scale production of 10K models is slated for the second quarter. Both drives also support UltraSCSI and Ultra2 LVD SCSI, and a Fibre Channel option is planned for the 10K sometime next year.
SAN and NAS Mean M&A
In the RAID market, the four leading systems vendors (Compaq, HP, IBM, and Sun) command about 60% of all revenues. That`s in part because their products are competitive with those from independent suppliers, but it`s also because end users often buy storage somewhat blindly from the same vendor that won the server sale.
SCSI vs. Fibre Channel Drives
The debate is raging over the future method of attaching hard drives to storage subsystems. Fibre Channel-Arbitrated Loop (FC-AL) is threatening to unseat parallel SCSI. Meanwhile, a new version of SCSI--Ultra160/m (a subset of the Ultra3 SCSI specification)--is emerging. (For more information on Ultra160/m, see News)
LSI augments MetaStor NAS devices
On the heels of its acquisition of Symbios, LSI Logic recently began shipments of the next generation of MetaStor "intelligent storage hubs."

Backup and Recovery for NT Clusters
With the increasing deployment of Windows NT Server Enterprise Edition, clustering is becoming a popular way of achieving high availability without the expense of deploying fault-tolerant redundant systems. Unlike redundant systems, which simply mirror the functions of the primary server and perform no additional tasks, clusters play a dual role. They run their own applications, such as e-mail or web access services, and they are capable of temporarily taking over the functions of any failed ser
Benchmarking a DLT Library
A combination of DLT tape drives and a robotic tape library puts high-speed multi-terabyte backup into the enterprise
