Chapter 23 Configuring FICON
MDS-Specific FICON Advantages
PortChannel Support
The Cisco MDS implementation of FICON provides support for efficient utilization and increased
availability of inter-switch links necessary to build stable large-scale SAN environments. PortChannels
ensure an enhanced ISL availability and performance in Cisco MDS switches.
VSANs for FICON and FCP Intermixing
Cisco MDS 9000 Family FICON-enabled switches simplify deployment of even the most complex
intermix environments. Multiple logical FICON, Z-Series Linux/FCP and Open-Systems FCP fabrics
can be overlaid onto a single physical fabric by simply creating VSANs as required for each service.
VSANs provide both hardware isolation and protocol specific fabric services, eliminating the
complexity and potential instability of zone-based intermix schemes.
By default, the FICON feature is disabled in all switches in the Cisco MDS 9000 Family. When the
FICON feature is disabled, FC IDs can be allocated seamlessly. Intermixed environments are addressed
by the SAN-OS software. The challenge of mixing Fibre Channel Protocol (FCP) and FICON protocols
are addressed by Cisco MDS switches when implementing VSANs.
Switches and Directors in the Cisco MDS 9000 Family support FCP and FICON protocol intermixing at
the port level. If these protocols are intermixed in the same switch, you can use VSANs to isolate FCP
and FICON ports.
Tip When creating an intermix environment, place all FICON devices in one VSAN (other than the default
VSAN) and segregate the FCP switch ports in a separate VSAN (other than the default VSAN). This
isolation ensures proper communication for all connected devices.
MDS-Supported FICON Features
The Cisco MDS 9000 Family FICON features include:
• Flexibility and investment protection--The Cisco MDS 9000 Family shares common switching and
service modules across all Cisco MDS 9500 Series as well as the Cisco MDS 9216 Switch. (refer to
the Cisco MDS 9500Series and the Cisco MDS 9216 Switch Hardware Installation Guides).
•
High-availability FICON-enabled director--The Cisco MDS 9500 Series combines nondisruptive
software upgrades, stateful process restart and failover, and full redundancy of all major components
for a new standard in director-class availability. It supports up to 224 2/1-Gbps, autosensing FICON
or Fibre Channel FCP ports in any combination in a single chassis and up to 768 Fibre Channel ports
in a single rack--1.44 Tbps of internal system bandwidth ensures smooth integration of future
10-Gbps modules.
• Infrastructure protection--Common software releases infrastructure protection is available across all
Cisco MDS 9000 platforms.
•
VSAN technology--The Cisco MDS 9000 Family introduces VSAN technology for
hardware-enforced, isolated environments within a single physical fabric for secure sharing of
physical infrastructure and enhanced FICON intermix support.
