Access "Modernize mainframe storage"

Published: 16 Oct 2012

  The best of both worlds Market pressures and new technologies are pushing the world of the mainframe and open systems together. Here's how: FICON, at 100MB/s, offers a faster replacement for 17MB/s ESCON interconnects and provides compatibility with Fibre Channel (FC) storage area networks (SANs) as well as the ability to span much longer distances. New storage management systems address both mainframe and open systems storage through a single interface. Hierarchical Storage Management (HSM), used for decades on mainframes, is becoming common in open systems environments as tape and slower nearline disk arrays move lesser-used data away from primary disk. Storage experts skilled in the mores of expensive mainframe storage are imposing tighter restrictions on their users than space-hungry open systems administrators. IBM's Linux on the mainframe provides the logical benefits of an open systems environment--such as a native SCSI stack--while retaining the large-scale benefits of the mainframe, such as the ability to run thousands of virtual servers.
