Cisco Fixes on FC Switches: Page 3 of 3

In addition, Cisco today rolled out version 1.2 of its MDS 9000 operating system, which includes:

  • LUN zoning, read-only zones, and port security;
  • Role-based VSAN access control;
  • Remote switched port analyzer (RSPAN), which extends the MDS 9000's switched port analyzer functionality to multiswitch environments; and
  • The ability to work in "legacy switch interoperability mode." So far, Cisco has tested this feature with Brocade switches; Harrington expects Cisco to test it with other vendors' switches running in native mode in the future.

However, the MDS switches still don't support Ficon. Cisco says the next upgrade of the SAN-OS -- due out before the end of the year -- will add support for Ficon, which Cisco is developing after licensing the Ficon control unit port (CUP) specifications from IBM.

The Cisco MDS 9100 switches are undergoing interoperability testing by EMC, HDS, HP, and IBM. Cisco says each storage vendor is expected to qualify the MDS 9100 and Cisco MDS 9000 SAN-OS 1.2 by the end of calendar year 2003. HP is expected to be the first to make the Cisco MDS 9100 available -- by the end of September -- with EMC and IBM following in early October.
