Evolving business requirements underscore the need for high-density, high-speed, and low-latency networks that improve data center scalability and manageability while controlling IT costs. As discussed in this document, the Cisco ® MDS 9000 Family provides the leading high-density, high-bandwidth storage networking solution along with Integrated Fabric Applications to support dynamic data center requirements. With the addition of the third-generation modules, the Cisco MDS 9000 Family of storage networking products support now 1-, 2-, 4-, 8-, and 10-Gbps Fibre Channel along with being Fibre Channel over Ethernet (FCoE) ready. One major benefit of the Cisco MDS 9000 family architecture is investment protection: the capability of first-, second- and third-generation modules to all coexist in both existing customer chassis and new switch configurations. A quick look at the storage area network (SAN) marketplace and the track record of delivery reveals that Cisco is the leader among SAN providers in delivering compatible architectures and designs that can adapt to future changes in technology, providing true investment protection.

New Challenges

1- , 2-, or 4-Gbps SAN connectivity is no longer sufficient to meet the needs of growing application server farms. Requirements to back up increasing amounts of data within a limited time frame, support increasing numbers of database transactions, and support bandwidth- and storage-intensive applications all underscore the need for high-density 8-Gbps and 10-Gbps Fibre Channel services. This shift in application requirements is also creating demand for network-based services to provide security, ease of migration, and disaster-recovery solutions.
In addition, data centers typically run multiple separate networks, including an Ethernet network for client-to-server and server-to-server communications and a Fibre Channel SAN. To support various types of networks, data centers use separate redundant interface modules for each network and redundant pairs of switches at each layer in the network architecture. Use of parallel infrastructures increases capital costs, makes data center management more difficult, and diminishes business flexibility. A unified fabric can meet these challenges, consolidating I/O in the data center and allowing Fibre Channel and Ethernet networks to share a single, integrated infrastructure. An important pillar of this design is FCoE. FCoE allows Fibre Channel frames to be encapsulated in Ethernet packets without using TCP/IP and is one of the technologies enabling unified I/O.
The Cisco MDS 9000 family offers both investment protection and a nondisruptive upgrade path to higher-port-density SAN switching, including 8-Gbps switching, network-based services, and support for FCoE all in the same chassis that shipped in 2002.

Business Benefits: Total Investment Protection

The introduction of third-generation hardware represents an evolutionary step for Cisco MDS 9000 family switches. The fundamental switch architecture and frame flow remain the same on all chassis, allowing modules from any generation to be mixed and matched.
Cisco provides investment protection by designing the system to support operation of previous-generation switching modules along with next-generation supervisors, switching modules, and chassis (Figure 2). In addition, the introduction of the new modules increases the scalability, flexibility and serviceability of the existing chassis.

Case Study

OhioHealth is a not-for-profit, charitable, healthcare organization that serves and supports the Ohio community. Based in Columbus, OhioHealth has a network of 17 hospitals, 20 health and surgery centers, home-health providers, and medical equipment and health service suppliers throughout a 46-county area.
OhioHealth has a central business office that handles the organization's scheduling, billing, and collections operations. OhioHealth also has offices in several locations, including its main hospital, Riverside Methodist Hospital; Grant Medical Center; Doctors Hospital; and Dublin Methodist Hospital. As the operations of the healthcare industry overall have increasingly become electronic and automated, the amount of data, especially in the areas of diagnostic imaging in radiology and cardiology, was on the rise at OhioHealth. The requirements for increased bandwidth and storage capacity became constant challenges, as were the requirements for business continuity and disaster recovery capabilities.
OhioHealth was already successfully using Cisco Catalyst ® 3750 Series Switches at the edge and Cisco Catalyst 6500 Series Switches at the core, with Cisco wireless solutions deployed throughout the network of hospitals for visitors and staff to access. The IT staff decided to upgrade the storage networking by deploying a Cisco SAN composed of two Cisco MDS 9509 Multilayer Directors with 244 ports on each switch: one for use at the primary data center and the other for the secondary data center. After evaluating storage switches on the market, the OhioHealth IT team selected the Cisco MDS 9000 family solution for its scalability, manageability, and investment protection. The Cisco MDS 9000 family also offered features such as VSANs that helped integrate connections between the two data centers and better utilize SAN resources.
