CNT embraces SAN strategy
Branching out from its mainframe roots, Computer Network Technology last month climbed into the budding market for storage area networks (SANs) for heterogeneous systems. The SAN market was pioneered by EMC.
According to Peripheral Research, a storage market research firm in Santa Barbara, CA, a SAN is "a high-speed network that establishes a direct connection between storage elements and servers." A SAN can be local or remote, shared or dedicated, and includes the following elements: external storage, centralized storage, and remote clustering (see table).
SAN interconnects can be SCSI, ESCON, SSA, Fibre Channel, or dedicated wide-area interconnects. One of the key advantages of SANs is that they externalize storage from indivicual servers so that storage can shared among multiple hosts without degrading system or network performance.
CNT is phasing in three SAN products:
The UltraNet Storage Director ($160,000) is a high-speed switching platform, due this month, that allows users to move data between OS/390, Windows NT, and UNIX platforms.
The UltraNet Storage Gateway ($35,000) is an entry-level product that enables data mirroring over wide-area networks. The gateway is due in January.
The UltraNet Storage Multiplexer ($12,000) allows multiple servers to share up to 15 storage devices. Due in November, the multiplexer supports SCSI and Fibre Channel interfaces.
CNT sells to storage and systems vendors, through VARs, and direct to end-users. For more information, contact Computer Network Technology at 800-638-8324 or visit www. cnt.com.
