The zDASD can now emulate up to 512 IBM 3390 data volumes, allowing IT administrators to deploy 13 terabytes of open systems disks as mainframe-attached DASD, according to the vendor. In addition, new dynamic path recognition capabilities allow individual data volumes to be easily allocated across multiple logical partitions (LPARs) and/or mainframes.
The new capabilities provide customers with an alternative for attaching low-cost storage, including Serial ATA disks, to IBM-compatible mainframes, reducing costs associated with second-tier storage in the process, Bus-Tech claimed. The zDASD 3990 Controller is a System 390 I/O controller providing FICON or ESCON attachment to mainframe, Gigabit Ethernet, Fibre Channel, or Ultra320 SCSI connections to open-system storage devices.
The controller provides a cost-effective alternative for data with intermediate retrieval requirements which may include compressed data, daily or weekly disk-to-disk backups, or large, infrequently used databases, the vendor said.
Pricing starts at $37,500.
