KEY FEATURES AND BENEFITS
Introducing the VSAN
VSANs allow more efficient storage network utilization by creating hardware-based isolated environments within a single physical SAN fabric or switch. Each VSAN can be zoned as a typical SAN and maintains its own fabric services for added scalability and resilience. VSANs allow the cost of SAN infrastructure to be shared among more users, while ensuring segregation of traffic and retaining independent control of configuration on a VSAN-by-VSAN basis.
To provide fabric isolation, the Cisco MDS 9216 supports Inter-VSAN Routing, the industry's first routing function for Fibre Channel. Inter-VSAN Routing allows selective transfer of data traffic between specific initiators and targets on different VSANs while maintaining isolation of control traffic within each VSAN. Using Inter-VSAN Routing, data can transit VSAN boundaries while maintaining control plane isolation, thereby maintaining fabric stability and availability.
Multiprotocol Intelligence for Investment Protection
The unique architecture of the Cisco MDS 9216 allows seamless integration of new transport protocols for maximum flexibility. Beginning with Fibre Channel, iSCSI, FCIP, and FICON the Cisco MDS 9216 is a robust multi-protocol platform designed for deployment of cost-optimized storage networks. Today, users can implement 2-Gbps Fibre Channel for high-performance applications, iSCSI over Ethernet for cost-effective connectivity to shared storage pools, FCIP for connectivity between data centers, and FICON for mainframe connectivity. The Cisco MDS 9216 is designed to support future storage protocols so that users can seamlessly migrate to new technologies while retaining a consistent set of features, services, and management tools.
ADVANCED TRAFFIC MANAGEMENT FOR HIGH-PERFORMANCE, RESILIENT FABRICS
The following advanced traffic-management capabilities integrated into the Cisco MDS 9216 simplify deployment and optimization of large-scale fabrics.
• Virtual Output Queuing ensures 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 port from any module in the chassis, ensuring that the bundle remains 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.
• Quality of service can be used to manage bandwidth and control latency, to prioritize critical traffic.
• Fibre Channel Congestion Control (FCC), an end-to-end, feedback-based congestion control mechanism, augments the Fibre Channel buffer-to-buffer credit mechanism to provide enhanced traffic management.
INDUSTRY'S MOST 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 9000 Family integrates the industry's most advanced analysis and diagnostic tools. Power-on self test (POST) and online diagnostics provide proactive health monitoring. The Cisco MDS 9216 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. Once traffic has been captured, it can then be analyzed with the Cisco Fabric Analyzer, an embedded Fibre Channel analyzer. Comprehensive port- and flow-based statistics facilitate sophisticated performance analysis and service-level agreement (SLA) accounting. With the Cisco MDS 9000 Family, Cisco Systems
® delivers the most comprehensive tool set for troubleshooting and analysis of storage networks.
COMPREHENSIVE SOLUTION FOR ROBUST SECURITY
Addressing the need for airtight security in storage networks, the Cisco MDS 9216 offers an extensive security framework to protect highly sensitive data crossing today's enterprise networks. The Cisco MDS 9216 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 LUNs are accessible only by specific hosts (LUN zoning), to limit SCSI read command for a certain zone (read-only zoning), and to restrict broadcasts to only the selected zones (broadcast zones). VSANs are used to achieve higher security and greater stability by providing complete isolation among devices that are connected to the same physical SAN. In addition, Fibre Channel Security Protocol (FC-SP) provides switch-switch and host switch Diffie-Hellman Challenge Handshake Authentication Protocol (DH-CHAP) authentication supporting RADIUS or TACACS+, to ensure that only authorized devices access protected storage networks.
This functionality, in conjunction with management access and control plane security, makes the Cisco MDS 9000 Family the most secure platform of its kind.
