Nondisruptive software upgrades-The MDS 9020 supports nondisruptive software upgrades to minimize service disruptions in a highly available storage area networking environment.

Scalability-Compatibility with all Cisco® MDS 9000 Family switches ensures scalability and consistent service delivery as your SAN grows.

Simplified storage management-The MDS 9020 includes built-in storage network management with all features available through a command-line interface (CLI) or Cisco Fabric Manager, a centralized management tool that simplifies management of multiple switches and fabrics.

Product Overview

Building Cost-Effective Intelligent Fabrics

The Cisco ® MDS 9020 Fabric Switch (Figure 1) offers advanced storage networking capabilities at new price points, allowing organizations of all sizes to enjoy the benefits of intelligent SANs. With twenty 4-Gbps Fibre Channel ports, the Cisco MDS 9020 is well suited for SMBs that want to deploy cost-effective but scalable, high-performance SANs. The Cisco MDS 9020 is also ideal for branch offices and departments in large enterprises. It can be used as the foundation of small standalone SANs or as an edge switch in larger core-edge SAN infrastructures.
The Cisco MDS 9020 provides the ideal balance of cost, performance, and basic enterprise-class features in a compact 1-RU form factor. Layering a requisite set of intelligent features onto a cost-effective, small-profile switching platform, the Cisco MDS 9020 meets the cost, performance, ease of management, and connectivity requirements of small and medium-scale storage environments. The Cisco MDS 9020 is fully compatible with the Cisco MDS 9500 Series Multilayer Directors and the Cisco MDS 9200 and MDS 9100 Series Multilayer Fabric Switches for transparent, end-to-end service delivery in large data-center core-edge deployments.

Key Features and Benefits

Industry-Leading 4-Gbps Performance and Scalability

With high port density in a 1-RU form factor that supports auto-sensing 1-, 2-, and 4-Gbps Fibre Channel technology, the Cisco MDS 9020 provides excellent value at an affordable price point. This allows even small businesses to achieve the levels of performance and availability typically attainable only by much larger enterprises. The Cisco MDS 9020 features a nonblocking architecture with as many as 20 ports concurrently active at 4-Gbps full duplex to provide an aggregate bandwidth of 160 Gbps.
The Cisco MDS 9020 works seamlessly with the rest of the Cisco MDS 9000 Family of Directors and Multilayer Fabric Switches, allowing multiple upgrade paths as smaller SANs scale and as multiprotocol functionality becomes necessary. The Cisco MDS 9020 offers full investment protection and can be migrated to the edge of a SAN deployment when coupled with larger core switches like the Cisco MDS 9200 and 9500 Series to introduce more advanced features and multiprotocol technology.

High Availability

The Cisco MDS 9020 is designed to provide high-availability switching for small-to-medium-sized storage networks. The Cisco MDS 9020 offers nondisruptive firmware upgrades (hot code load activation) to help ensure high availability throughout the fabric. It also offers Fabric Shortest Path First (FSPF) traffic rerouting for redundant path failover and extensive diagnostics for quick troubleshooting.
Greater levels of availability can be achieved with the Cisco MDS 9020 at the edge in a core-edge deployment with multiple redundant network paths connected into a core of Cisco MDS9500 Series Directors or MDS 9200 Series Multilayer Fabric Switches.

Ease of Management

Delivering SAN capabilities means delivering management capabilities. To meet the needs of all users, the Cisco MDS 9020 provides three principal modes of management: a CLI consistent with the Cisco MDS 9000 Family, the Cisco Fabric Manager, and integration with third-party storage management tools.
The Cisco MDS 9020 presents a consistent, logical CLI. Adhering to the syntax of the widely known Cisco IOS® Software CLI, the Cisco MDS 9020 CLI is easy to learn and delivers broad management capability. The Cisco MDS 9020 CLI is an extremely efficient and direct interface designed to provide optimal capability 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 helps 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, enabling 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.
