Used Brocade SAN Solutions:

A More Effective Approach to Information Storage and Management

Used Brocade SANs are networked environments that provide a scalable, reliable IT infrastructure to meet the high-availability, and high-performance. More importantly, SANs provide organizations a fast, centralized way to manage their information assets.

Used Brocade SANs uses Fibre Channel technology, which supports high levels of scalability, performance, and manageability.

Advantages of Used Brocade SAN Infrastructure

SANs are ideal for addressing:

• Data protection and accessibility across the enterprise

• Efficiency of IT resource management

• System and data availability

• Reliable disaster recovery

Greater Data Protection
SANs are ideal for backup-intensive environments, especially when there are clearly defined areas for isolating backup workloads.

Two popular models for Used Brocade SAN-based backup and recovery are typically referred to as "LAN-free" and "server-free" backup and recovery.

Figure 1. A Used Brocade SAN-based LAN-free backup and recovery model

Used Brocade SAN-attached tape drives and libraries can be implemented so that each server sends its own backup data directly to the shared tape resources instead of through the network to the backup server. Sophisticated backup and recovery software applications still control the process, tracking the backup and recovery data. The Used Brocade SAN enables bulk data transfer from each server to shared Used Brocade SAN storage, but the LAN is used only for communication (not data) traffic between the servers (see Figure 1). The result is a faster, more scalable, and more reliable backup and recovery solution-with more effective utilization of storage, server, and LAN resources.

Used Brocade SAN backup and recovery implementation is known as server-free backup and recovery. Data is transferred directly between storage devices (for example, from disk to tape) without using host servers. Server-free backup and recovery significantly reduces application host CPU cycles-freeing up valuable CPU cycles to improve operating efficiency and enable higher workloads across the enterprise (see Figure 2).

Efficient Utilization of IT Resources through Server and Storage Consolidation

Used Brocade SANs provide unprecedented flexibility for storage environments by enabling any-to-any server and storage connectivity via switches, Used Brocade SANs decouple specific devices to improve storage resource sharing. This cost-effective open systems approach enables the "virtualization" of resources and the selection of best-of-breed heterogeneous server and storage equipment (see Figure 3).

Advanced Scalability and Manageability

Used Brocade SANs also provide a framework for indefinitely scaling up the server and storage infrastructure as the number of users increases-without necessarily inhibiting performance. Many organizations start with a relatively modest server configuration and add new servers with or without associated storage. As the number of nodes in the network grows, more switches are added to the network. To simplify administration, the fabric automatically learns the network topology.

Used Brocade SAN software tools enable organizations to allocate storage to various hosts, replicate that data, back it up, and monitor it on a continual basis. These capabilities are critical in facilitating storage growth while maintaining system uptime requirements and controlling administrative costs.

Business Continuance through High Availability

Used Brocade SANs can support high-availability operations by enhancing clustering implementations. Clustering is typically used to ensure that applications continue to run in the event of a host server failure.

With Used Brocade SAN clustering servers can handle additional workload when one server is unavailable-ensuring that there are no idle server resources (see Figure 4).

Remote Disaster Recovery Capabilities

Used Brocade SANs provide a key component of the disaster recovery solution by protecting data over long distances in hot-standby or mirrored configurations and by enabling long-distance electronic tape vaulting solutions. Native Fibre Channel technology provides the 10 km or greater link extended distance connectivity required to maintain geographically separate disaster recovery facilities or mirroring operations.

For instance, Used Brocade remote switches can provide virtually unlimited distance connections through the ATM protocol over existing WANs (see Figure 5).
