Main Features and Benefits
Exceptional Flexibility and Scalability
The Cisco MDS 9124 offers up to 24 autosensing Fibre Channel ports capable of speeds of 4, 2, and 1 Gbps in a compact 1RU form-factor chassis. With 4 Gbps of dedicated bandwidth for each port, the Cisco MDS 9124 is designed to meet the performance and scalability requirements of the most demanding environments.
The flexibility of the Cisco MDS 9124 is provided by the Cisco MDS 9124 On-Demand Port Activation licenses, which allow expansion in 8-port increments. Customers can start with a base configuration of 8 ports and can upgrade onsite to 16 and 24 ports using these licenses. With advanced storage networking capabilities built into the platform, it is an ideal choice both as a standalone departmental SAN switch and as an edge switch in enterprise core-edge SANs.
The Cisco MDS 9124 includes hot-swappable, Small Form-Factor Pluggable (SFP), LC interfaces. All SFP interfaces are 4, 2, and 1 Gbps, with autosensing capabilities. Individual ports can be configured with either short-or long-wavelength SFP optics for connectivity up to 500 meters (m) and 10 kilometers (km), respectively.
VSANs for Segmentation and Isolation
VSAN, an industry standard for fabric virtualization capabilities, allows more efficient storage network use by creating hardware-based isolated environments within a single physical SAN fabric or switch. Up to 16 VSANs are supported per switch. Each VSAN can be zoned as a typical SAN and maintains its own fabric services and management domains for added scalability and resilience. VSANs allow the cost of SAN infrastructure to be shared among more users, while helping ensure segregation of traffic and retaining independent control of configuration on a VSAN-by-VSAN basis.
Advanced Traffic Management for High-Performance, Resilient SANs
Advanced traffic management capabilities integrated into the Cisco MDS 9124 simplify deployment and optimization of core-edge fabrics.
• Virtual output queuing helps ensure line-rate performance on each port, independent of traffic pattern, by eliminating head-of-line blocking.
• Each port group consisting of 4 ports has a pool of 64 buffer credits, with a default of 16 buffer credits per port. When extended distances are required, up to 61 buffer credits can be allocated to a single port within the port group. This extensibility is available without additional licensing.
• PortChannels allow users to aggregate up to 16 physical ISLs into a single logical bundle, providing optimized bandwidth use across all links. The bundle can consist of any port from the switch, helping ensure that the bundle remains active even in the event of a port group 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.
• Comprehensive port and flow statistics facilitate sophisticated performance analysis and service-level agreement (SLA) accounting.
Advanced Diagnostics and Troubleshooting Tools
Management of storage networks requires proactive diagnostics, tools to verify connectivity and route latency, and mechanisms for capturing and analyzing traffic. The Cisco MDS 9124 integrates the industry's most advanced analysis and debugging tools. Power-on self-test (POST) and online diagnostics provide proactive health monitoring. The Cisco MDS 9124 provides the integrated hardware functions required to implement diagnostic capabilities such as Fibre Channel Traceroute to detail the exact path and timing of flows and SPAN to intelligently capture network traffic. After traffic has been captured, it can be analyzed with the Cisco Fabric Analyzer, an embedded Fibre Channel analyzer. With the Cisco MDS 9124, Cisco delivers a comprehensive toolset for troubleshooting and analysis of an organization's storage network.
Recognizing the need for unassailable security in storage networks, the Cisco MDS 9124 offers an extensive security framework to protect highly sensitive data crossing today's enterprise networks.
• VSANs are used to achieve higher security and greater stability by providing complete isolation among devices that are connected to the same physical SAN.
• Intelligent packet inspection at the port level, including the application of access control lists (ACLs) for hardware enforcement of zones, VSANs, and advanced port security features.
• Extended zoning capabilities help ensure that broadcasts are restricted to the selected zones (the broadcast zones).
• FC-SP provides switch-to-switch and host-to-switch Diffie-Hellman Challenge Handshake Authentication Protocol (DH-CHAP) authentication supporting RADIUS or TACACS+ to help ensure that only authorized devices access protected storage networks.
This framework, in conjunction with management access and control plane security, makes the Cisco MDS 9000 Family among the most secure platforms of its kind.
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.
High-Availability Platform for Mission-Critical Environments
The Cisco MDS 9124 is designed for mission-critical availability. Nondisruptive software upgrades; hot-swappable, redundant fans and power supplies; and the unique ability to automatically restart failed 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. The Cisco PortChannels feature allows users to aggregate up to 16 physical ports into one logical bundle. The bundle can sustain the failure of any physical link without causing a reset. Additionally, FSPF multipathing provides the intelligence to load-balance across up to 16 equal-cost paths and, if a switch fails, to dynamically reroute traffic. The Cisco MDS 9124 dramatically increases fabric-switch availability, reducing TCO.
When the Cisco MDS 9124 is deployed as an edge switch, the Cisco N-Port Virtualization (NPV) mode support provides resiliency on uplinks to the core. The NPV fabric-port (F-port) trunking and channeling features also enable SANs to be scaled without reaching Fibre Channel domain ID limits.
The Cisco MDS 9124 provides three principal modes of management: the Cisco MDS 9000 Family CLI, the Cisco DCNM for SAN Essentials Edition, and integration with third-party storage management tools.
• Consistent, logical CLI: Adhering to the syntax of the widely known Cisco IOS® Software CLI, the Cisco MDS 9000 Family CLI is easy to learn and delivers broad management capabilities. The Cisco MDS 9000 Family CLI is an extremely efficient and direct interface designed to provide optimal capabilities to administrators in enterprise environments.
• Quick Configuration Wizard: The Quick Configuration Wizard helps eliminate management complexity and creates a readily available SAN environment for small- and mid-sized business applications. The wizard allows server access to storage to be set up quickly and easily in a single step, using an intuitive GUI.
• Cisco DCNM: Cisco DCNM can be licensed for management of a combination of SAN and LAN environments. Cisco DCNM streamlines the provisioning of the unified fabric and proactively monitors the LAN and SAN components. Cisco DCNM for SAN Essentials Edition (formerly Cisco Fabric Manager), which comes standard with the Cisco MDS 9124, is an easy-to-use application that simplifies management across multiple switches and converged SAN fabrics. Focused on supporting efficient operations and management of virtual machine-aware fabrics, Cisco DCNM for SAN Essentials Edition provides a robust framework and comprehensive feature set that meets the routing, switching, and storage administration needs of present and future virtualized data centers. The optional Cisco DCNM for SAN Advanced Edition (formerly Cisco Fabric Manager Server) extends the standard Cisco DCNM for SAN Essentials Edition software by providing server federation, historical performance monitoring for network traffic hotspot analysis, centralized management services, and advanced application integration. All standard Cisco DCNM for SAN Essentials Edition features and functions are fully integrated with the optional Cisco DCNM for SAN Advanced Edition capabilities.
• APIs: The Cisco MDS 9124 provides an extensive set of APIs for integration with third-party and user-developed management tools. The APIs are based on industry-standard protocols, including SNMP and the Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S).
