Bus-Tech Announces New Enhancements of the zDASD; New Features Offer Increased Storage Capacity Combined with Improved Flexibility.BURLINGTON, Mass. -- Today, Bus-Tech(R), Inc., a leading supplier of data center connectivity products, announced significant enhancements to the zDASD 3990 Controller, its leading product for connecting mainframes to open system storage products in support of DASD (Direct Access Storage Device) Pronounced "daz-dee." A peripheral device that is directly addressable, such as a disk or drum. The term is used in the mainframe world. DASD - Direct-Access Storage Device (ECKD ECKD Extended Count Key Data Device ) file access. With these enhancements, zDASD can now emulate up to 512 IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) 3390 data volumes; allowing IT administrators to deploy 13 Terabytes (TB) of open systems disks as mainframe-attached DASD. Additionally, new dynamic path recognition capabilities allow individual data volumes to be easily allocated across multiple logical partitions (LPARs) and/or mainframes. These new capabilities provide customers with a highly flexible alternative for attaching low-cost storage, including serial-ATA disks, to their IBM compatible (computer) IBM compatible - A computer which can use hardware and software designed for the IBM PC (or, less often, IBM mainframes). This was once a key phrase in marketing a new PC clone but now in 1998 is rarely used, the non-IBM wintel personal computer manufacturers such mainframes; drastically reducing the costs associated with second tier storage. The zDASD 3990 Controller is a System/390 input/output controller providing FICON (FIber CONnector) An IBM mainframe channel introduced with its G5 servers in 1998. Based on the Fibre Channel standard, it boosts the transfer rate of ESCON's half-duplex 17MB/sec to a full-duplex 100MB/sec. or ESCON (Enterprise Systems CONnection) An IBM S/390 fiber-optic channel that transfers 17 Mbytes/sec over distances up to 60 km depending on connection type. ESCON allows peripheral devices to be located across large campuses and metropolitan areas. attachment to the mainframe and Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. , Fibre Channel, or Ultra320 SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. connection to open-system storage devices. Data written by the mainframe to zDASD devices is stored on open-systems storage in such a way as to allow the data to be retrieved in exactly the same format as it was stored. This makes it transparent to the mainframe hardware and/or operating systems Operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. that the data has been stored on open-systems storage rather than traditional mainframe storage. Bus-Tech's zDASD controller provides a cost-effective storage alternative for data with intermediate retrieval requirements which may include compressed data, daily or weekly disk-to-disk backups, large infrequently used databases, archived report data, and more. With the advances in Serial ATA disk technology in reliability, density and performance along with the capabilities of zDASD, customers now have increased options for their near term storage needs. "zDASD uses open-system storage for mainframe DASD applications providing cost-conscious IT administrators with lower cost open-systems arrays for their secondary or tertiary storage needs," said Ralph Armstrong, Vice President of Product Management. "By emulating up to 512 data volumes, we are offering significantly greater storage capacity which translates directly into cost savings and flexibility for our customers." About Bus-Tech, Inc.
