Seamlessly sharing data center tape libraries with distributed systemsLet's say you have some highly reliable STK tape libraries with ESCON interfaces, but you also have some new UNIX-based processors with SCSI interfaces located either in the same data center or in remote locations. You can use those tape libraries for your UNIX processor storage with the Channelink SCSI Gateway.The SCSI Gateway has an OEMI or ESCON interface on one side, and a SCSI interface on the other. It can act as a stand-alone gateway or be a part of an extended Channelink network. Combining the SCSI Gateway hardware with Parallel Data Mover software creates FileSpeed software which provides for quick and reliable bulk data transfers between MVS systems and open systems like UNIX servers without the need for network protocols. The result, sharing of Enterprise storage devices and Enterprise data centrally managed using the standard tools available in today's host environments. The Channelink SCSI Gateway connects systems using ESCON and bus-and-tag channels systems with SCSI-attached systems at high speeds, giving flexibility to network managers in choosing where data is stored and processed. Mainframes typically have ESCON or bus-and-tag channels, while UNIX systems and many other kinds of computers are equipped with the Small Computer Systems Interface, or SCSI, channel, which uses a different protocol. The Channelink SCSI Gateway acts as a high-speed translator between these different types of systems and also allows computers and peripherals to be farther apart beyond the standard distance limits of these channels. With the SCSI Gateway, companies can store data on reliable mainframe tapes, for example, but process it on distant, specialized UNIX machines, making their enterprise networks more flexible.
