IBM System Storage SAN24B-4 Express

Designed for high-performance, scalability and simple-to-use in small to medium-size SAN environments

Highlights

The IBM System Storage SAN24B-4 Express fabric switch is designed specifically to address the needs of small to medium-sized 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 which support fabric connectivity and advanced business continuity capabilities. Infrastructure simplification solutions for IBM System x, BladeCenter and IBM Power Systems servers include storage consolidation and high-availability (HA) server clustering with IBM System Storage disk storage arrays. Business continuity solutions include data protection with IBM System Storage tape libraries and devices and IBM Tivoli Storage Manager (TSM) data protection software.

A single SAN24B-4 Express switch can serve as the cornerstone of a SAN for those that want to obtain the benefits of storage consolidation and are just beginning to implement FC storage systems. Such an entry-level configuration can consist of one or two FC links to a disk storage array or to a Linear Tape-Open (LTO) 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 HA 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 FC adapters cross-connected to redundant SAN24B-4 Express switches, which are cross connected to a dual-controller storage system. While the focus of the SAN24B-4 Express is as the foundation of 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 and TotalStorage SAN b-type and m-type families. This capability helps provide investment protection as SAN requirements evolve and grow over time.
