Integrated Mainframe Support
The Cisco MDS 9216A multilayer fabric switch is mainframe-ready, with full support for IBM zSeries FICON and Linux environments.
Qualified by IBM for attachment to all FICON-enabled devices in an IBM zSeries operating environment, Cisco MDS 9216A multilayer fabric
switches support transport of the FICON protocol in both cascaded and noncascaded fabrics, as well as an intermix of FICON and open systems
Fibre Channel Protocol traffic on the same switch. VSANs simplify an intermix of SAN resources between z/OS, mainframe Linux, and open
systems environments, allowing for increased SAN utilization and simplified SAN management. VSAN-based intermix mode eliminates the
uncertainty and instability often associated with zoning-based intermix techniques. VSANs also eliminate the possibility of a misconfiguration
or component failure in one VSAN affecting operation in other VSANs. VSAN-based management access controls simplify partitioning of SAN
management responsibilities between mainframe and open systems environments, enhancing security. FICON VSANs can be managed using the
integrated Cisco Fabric Manager; the Cisco CLI; or IBM CUP-enabled management tools, including SA/390, Resource Measurement Facility
(RMF), or Dynamic Channel Path Management (DCM).
Advanced Traffic Management
The following advanced traffic management capabilities integrated into the Cisco MDS 9216A simplify deployment and optimization of large-
scale fabrics:
●
Virtual Output Queuing—helps ensure line-rate performance on each port, independent of traffic pattern, by eliminating head-of-line
blocking.
●
255 buffer-to-buffer credits—are assigned to each port for optimal bandwidth utilization across distance.
●
PortChannels—Allow users to aggregate up to 16 physical ISLs into a single logical bundle, providing optimized bandwidth utilization across
all links. The bundle can consist of any speed-matched ports from any module in the chassis, ensuring that the bundle can remain active
even in the event of a module failure.
●
Fabric Shortest Path First (FSPF)–based multipathing—provides the intelligence to load balance across up to 16 equal cost paths and, in the
event of a switch failure, dynamically reroute traffic.
●
QoS—can be used to manage bandwidth and control latency, to prioritize critical traffic.
●
Fibre Channel Congestion Control (FCC)—is an end-to-end, feedback-based congestion control mechanism that augments the Fibre Channel
buffer-to-buffer credit mechanism to provide enhanced traffic management.
Advanced Diagnostics and Troubleshooting Tools
Management of large-scale storage networks requires proactive diagnostics, tools to verify connectivity and route latency, and mechanisms for
capturing and analyzing traffic. The Cisco MDS 9216A integrates advanced analysis and diagnostic tools. Power-on self test (POST) and online
diagnostics provide proactive health monitoring. The Cisco MDS 9216A implements diagnostic capabilities such as Fibre Channel Traceroute
for detailing the exact path and timing of flows and Switched Port Analyzer (SPAN) to intelligently capture network traffic. After traffic has
been captured, it can then be analyzed with the Cisco Fabric Analyzer, an embedded Fibre Channel analyzer. Comprehensive port-based and
flow-based statistics facilitate sophisticated performance analysis and service-level agreement (SLA) accounting. With the Cisco MDS 9216A,
Cisco Systems

delivers a comprehensive toolset for troubleshooting and analysis of storage networks.
Comprehensive Solution for Robust Security
Addressing the need for failproof security in storage networks, the Cisco MDS 9216A offers an extensive security framework to protect highly
sensitive data crossing today’s enterprise networks. The Cisco MDS 9216A employs intelligent packet inspection at the port level, including
the application of ACLs for hardware enforcement of zones, VSANs, and advanced Port Security features.
Extended zoning capabilities are enabled to ensure that logical unit numbers (LUNs) are accessible only by specific hosts (LUN zoning), to limit
SCSI read commands for a certain zone (read-only zoning), and to restrict broadcasts to only the selected zones (broadcast zones). VSANs are
