Networking to small and medium-scale SANs and data-center edge applications. The Cisco MDS 9100 Series provides the ideal balance of cost, performance, and enterprise-class features in a compact 1RU form factor.
Available in 20- and 40-port configurations, the Cisco MDS 9100 Series offers the port densities required for a wide variety of storage environments. Providing class-leading scalability, availability, security, and management, the
Cisco MDS 9100 Series enables users to deploy high-performance SANs with low TCO. Layering a rich set of intelligent features onto a cost-effective, small-profile switching platform, the Cisco MDS 9100 Series addresses the cost, performance, ease of management, and connectivity requirements of small and medium-scale storage environments and provides full-feature compatibility with Cisco MDS 9500 Series Multilayer Directors and the
Cisco MDS 9200 Series Multilayer Fabric Switches for transparent, end-to-end service delivery in large data-center core-edge deployments.
Cisco MDS 9100 Series switches optimize connectivity by matching switch-port performance to the requirements of connected devices. Target-optimized ports are configured to meet the bandwidth demands of high-performance storage devices, servers, and Inter-Switch Links (ISLs). Host-optimized ports deliver best-in-class port density and optimal bandwidth for host-attach. The Cisco MDS 9120 model switch is configured with 16 host-optimized ports and 4 target-optimized ports. The Cisco MDS 9140 model switch is configured with 32 host-optimized ports and 8 target-optimized ports. Cisco MDS 9100 Series switches include hot-swappable, Small Form-Factor Pluggable
(SFP), LC interfaces. Individual ports can be configured with either short- or long-wavelength SFPs for connectivity up to 500m and 10 km, respectively. Available coarse wavelength-division multiplexing (CWDM) SFPs support aggregation of multiple links onto a single optical fiber through a low-cost, passive, optical multiplexer/demultiplexer. All interfaces are 2 Gbps compatible. Up to 255 buffer credits per port are supported on target-optimized ports for maximum extensibility without the requirement for additional licensing. Host-optimized ports support 12 buffer credits per port.
Advanced Traffic Management for High-Performance, Resilient Fabrics
Advanced traffic management capabilities integrated into the Cisco MDS 9100 Series 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.
When extended distances are required, up to 3,500 credits can be allocated to a single port within a group of four Fibre Channel ports.
PortChannels allow users to aggregate up to 15 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
15 equal cost paths and, in the event of a switch failure, dynamically reroute traffic.
Quality of Service (QoS) can be used to manage bandwidth and control latency, in order to prioritize critical traffic.
● Fibre Channel Congestion Control (FCC), an end-to-end feedback-based congestion control mechanism, augments the Fibre Channel’s Buffer-to-Buffer credit mechanism to provide enhanced traffic management.
Key Features and Benefits
VSANs and INTER-VSAN Routing Enhance Security and Stability
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 assuring absolute segregation of traffic and retaining independent control of configuration on a VSANby-VSAN basis.
The Cisco MDS 9100 Series supports Inter-
VSAN Routing (IVR), the industry’s first routing functionality for Fibre
Channel. IVR allows selective transfer of data traffic between specific initiators and targets on different VSANs while maintaining isolation of control traffic within each VSAN. With IVR, data can transit VSAN boundaries while maintaining control plane isolation, thereby maintaining fabric stability and availability.
Smart Zoning: When the Smart Zoning feature is enabled, Cisco MDS 9000 Family fabrics provision the hardware access control entries specified by the zone set more efficiently, avoiding the superfluous entries that would allow servers (initiators) to talk to other servers, or allow storage devices (targets) to talk to other storage devices. This feature makes larger zones with multiple initiators and multiple targets feasible without excessive consumption of hardware resources. Thus, smart zones can correspond to applications, application clusters, hypervisor clusters, or other data center entities, saving the time that administrators previously spent creating many small zones, and enabling the automation of zoning tasks.
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 debug tools. Power-on self test (POST) and online diagnostics provide proactive health monitoring. Cisco MDS 9100 Series provides the integrated hardware functionality required to implement diagnostic capabilities such as FC 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 enable sophisticated performance analysis and service level agreement (SLA) accounting. With the MDS
9000 Family, Cisco delivers the mos t comprehensive toolset for troubleshooting and analysis of an organization’s storage network.
Comprehensive Solution for Robust Security
Recognizing the need for airtight security in storage networks, the Cisco MDS 9100 Series offers an extensive security framework to protect highly sensitive data crossing today’s enterprise networks. The Cisco MDS 9100
Series 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 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.
The Cisco MDS 9100 Series was designed for class-leading availability. Hot-swappable, redundant fans and power supplies and the unique ability to automatically restart failed supervisor processes combine to define a new standard for fabric switch availability. High availability is implemented at the fabric level through the industry’s most robust and highest-performance ISLs. PortChannel capability allows users to aggregate up to 15 physical links
(Cisco MDS 9140) into one logical bundle. The bundle can sustain the failure of any physical link without causing a reset. Additionally, Fabric-Shortest-Path-First (FSPF) multipathing provides the intelligence to load balance across up to 15 equal cost paths (Cisco MDS 9140) and, if a switch fails, to dynamically reroute traffic. The Cisco MDS
9100 Series takes fabric-switch availability to a new level, minimizing TCO.
Ease of Management
Delivering on the promise of SANs means delivering on management capabilities. To meet the needs of all users, the Cisco MDS 9100 Series provides three principal modes of management: Cisco MDS 9000 Family CLI, Cisco
Fabric Manager, and integration with third-party storage management tools. The Cisco MDS 9100 Series presents the user with a consistent, logical CLI. Adhering to the syntax of the widely known Cisco IOS
CLI, the Cisco MDS
9000 Family CLI is easy to learn and delivers broad management functionality. The Cisco MDS 9000 Family CLI is an extremely efficient and direct interface designed to provide optimal functionality to administrators in enterprise environments. Cisco Fabric Manager is a responsive, easy-to-use Java application that simplifies management across multiple switches and fabrics. Cisco Fabric Manager enables administrators to perform vital tasks such as topology discovery, fabric configuration and verification, provisioning, monitoring, and fault resolution. All functions are available through a secure interface, which enables remote management from any location. Cisco Fabric
Manager may be used independently or in conjunction with third-party management applications. Cisco provides an extensive API for integration with third-party and user-developed management tools.
