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 (ECKD) file access.
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.
The project resulted in a set of inventory reports listing all software components and the associations between them, exception reports listing missing components, usage reports showing active and non-active components, and the associated DASD
LUMINEX also certifying INNOVATION's FDRPAS as a V/B 3390 solution for non-disruptive installation and real time replication of existing mainframe DASD
storage data to V/B 3990-based DASD
This unique Bus-Tech technology allows IT administrators to deploy open systems disks as mainframe-attached DASD
