IBM Systems and Technology Data Sheet System Storage IBM System Storage SAN24B-4 Express ­ Designed for high performance and scalability in small- to medium-sized SAN environments Benefit from easy-to-install and easy-touse features designed specifically for small- to medium-sized environments Reach new performance levels with 8 Gbps Fibre Channel technology Scale from 8 to 16 to 24 ports with Ports on Demand Protect existing 4, 2 and 1 Gbps infrastructure investments while positioning for future technologies Use as the foundation for new infrastructure simplification and business continuity solutions for servers running Microsoft Windows, Linux, IBM® AIX® and other selected operating systems The IBM System Storage® SAN24B-4 Express fabric switch is designed specifically to address the needs of small- to medium-sized storage area network (SAN) environments. It can be used to create a wide range of high-performance SAN solutions, from simple, single-switch configurations to larger, multi-switch configurations that support fabric connectivity and advanced business continuity capabilities. Infrastructure simplification solutions for servers include storage consolidation and high-availability server clustering with IBM disk storage arrays. Business continuity solutions include data protection with IBM tape libraries and devices and IBM Tivoli® Storage Manager data protection software. A single SAN24B-4 switch can serve as the cornerstone of a SAN for those who want to obtain the benefits of storage consolidation and are just beginning to implement Fibre Channel storage systems. Such an entry-level configuration can consist of one or two Fibre Channel links to a disk storage array or to a Linear Tape-Open (LTO) Ultrium tape drive. An entry-level, eight-port storage consolidation solution can support up to seven servers with a single path to either disk or tape. The Ports on Demand feature is designed to enable a base switch to grow to 16 and 24 ports to support more servers and more storage devices without taking the switch offline. A high-availability solution can be created with redundant switches. This capability is ideal for server clustering environments. Such a configuration can support from 6 to 22 servers, each with dual Fibre Channel adapters cross-connected to redundant SAN24B-4 switches, which are cross-connected to a dual-controller storage system. While the focus of SAN24B-4 is to serve as the foundation of

IBM Systems and Technology Data Sheet System Storage small- to medium-sized SANs, it can be configured to participate as a full member in an extended fabric configuration with other members of the IBM System Storage SAN b-type families. This capability helps provide investment protection as SAN requirements evolve and grow over time. The introduction of large-capacity, high-availability storage systems offers new opportunities for cost reduction through storage consolidation and infrastructure and management simplification. In older environments, each server accessed its own dedicated storage...

IBM Systems and Technology Data Sheet System Storage required for some optional features. FOS offers the following advanced functions (either included in the base switch or as optional features): ●● ● Adaptive networking services is a set of features that provides users with tools and capabilities with which to incorporate network policies to ensure optimal behavior of a large SAN. It uses network intelligence to anticipate congestion and to dynamically make adjustments in the fabric so that application traffic continues to flow. Advanced performance monitoring helps identify end-toend bandwidth...
