In this document you will learn the options available to design a robust, flexible, and high performance storage area network SAN built using the Cisco MDS 9. Series fabric switches. This document also covers best practices to increase scalability and operational simplicity. Key software enhancements to provision and manage your SAN are also discussed. The focus of this document is on the Cisco MDS 9. Adobe Director 11 Serial Number' title='Adobe Director 11 Serial Number' />S 1. G Multilayer Fabric Switch and the Cisco MDS 9. S 1. 6G Multilayer Fabric Switch, as shown in Figure 1. Figure 1.       Cisco MDS 9. S and 9. 39. 6S Fabric Switches. The principles described here apply to director class platforms as well. Detailed design information for the director class platforms is available in the Large SAN Design Best Practices Using Cisco MDS 9. MDS 9. 50. 0 Multilayer Directors white paper. The purpose of a SAN is to provide connectivity between end devices servers and storage arrays. To increase high availability, two paths are maintained between same pair of servers and storage arrays. Servers are installed with at least dual port host bus adapters HBA which are connected to ports on two different controllers on storage arrays. The dual path connectivity between servers and storage arrays is provided by two distinct SANs built using one or more switches. These dual networks are commonly known as SAN A and SAN B. Both SANs are designed to be identical. This document shows only a single SAN in the network diagrams for the sake of simplicity.

The subsections that follow elaborate on the options available to build a SAN using Cisco MDS fabric switches. The MDS 9. 14. 8S and MDS 9. S can be used to connect 4. Solutions built using a single switch are simple to design, install, manage, and operate.

Figure 3. Figure 3. Flexible Licensing on MDS 9. S for up to 9. 6 Ports. A fabric built using multiple switches can be used to provide connectivity among more than 9. You should carefully analyze application throughput requirements and traffic patterns to make decisions regarding topology, network oversubscription, number of inter switch links ISLs, level of high availability, and switch model. Consider the network shown in Figure 4. Pc Game Conflict Global Storm Download. Two MDS 9. 39. 6S switches are used to provide connectivity among 1. Twenty four ports on each MDS 9. S are used for ISL connectivity. Assuming that all links are at 1. G Fibre Channel, the network shown has an oversubscription ratio of 3 1 between the two switches. The network can be further optimized by increasing traffic localization. Figure 4.       Multiswitch Solution Using MDS 9. S Switches. Cisco MDS fabric switches can be used at the server edge in large scale edge core or edge core edge designs. Server edge switches can be installed at the top of a rack TOR. TOR switches can be connected to Cisco MDS 9. Series Multilayer Directors installed at the end of a row EOR. The number, model, and port count of switches are derived from the number of servers installed per rack and the traffic profile. The MDS 9. 39. 6S can increase consolidation by acting as a shared TOR switch between multiple racks. A reduced number of TOR switches leads to reduced management overhead and reduced real estate, power, cooling, and cabling requirements, leading to lower operating expenses Op. Ex. The MDS 9. 14. S and MDS 9. 39. 6S can be configured in N Port Virtualization NPV mode with MDS 9. Series directors acting as the N Port Identifier Virtualization NPIV parents Figure 5. Servers should maintain dual paths to reach storage arrays. The design shown in Figure 5 should be replicated in dual networks SAN A and SAN B. Switches in NPV mode do not consume a Fibre Channel domain ID or join a fabric. Multiple end devices connected to a switch in NPV mode can log in to a fabric using the same port on the parent NPIV switch. The NPV and NPIV model simplifies management and increases scalability, especially in large networks. NPV and NPIV functionality is included in the base license. Figure 5.       MDS 9. S in NPV Mode at the Server Edge in a Large Scale Edge Core Edge Design. The MDS 9. 39. 6S can be used for replication and backup services over long distance native Fibre Channel links Figure 6. By default, all ports on the MDS 9. S have 5. 00 buffer to buffer B2. B credits. This quantity is enough for a 6. Fibre Channel link, assuming full size frames of 2. The number of B2. B credits can be increased up to 4. This quantity is enough for a 5. Fibre Channel link, assuming full size frames of 2. Figure 6.       MDS 9. S in a Native Fibre Channel SAN Extension Solution. Table 1 lists the number of B2. B credits required per kilometer of ISL at different speeds and frame sizes. Note that one B2. B credit is needed per frame irrespective of the frame size. Also, scope should be left for a longer end to end path in the optical WANMAN infrastructure and with small frame sizes. Table 1.        Per Kilometer B2.

More details are available in the Cisco MDS 9. Family Pluggable Transceivers data sheet. The following best practices should be used while designing and operating a SAN using Cisco MDS 9. Series fabric switches. Servers and storage arrays in the same zone should be connected to the same switch in a two switch network Figure 7. This approach increases traffic localization and decreases traffic flow on the ISL. Traffic localization brings the following benefits.
