| Highlights |
| * Simple-to-use SAN switch with easy-to-install and easy-to-use features designed specifically for the needs of small to medium-size environments * Provides new levels of performance with 8 Gbps Fibre Channel (FC) technology * “Ports on Demand” scalability from 8 to 16 to 24 ports * Protect existing 4, 2 and 1 Gbps infrastructure investment while positioning for future technologies * Foundation for new infrastructure simplification and business continuity solutions for servers running Microsoft® Windows®, Unix®, Linux® and IBM AIX® and OS/400® operating systems |
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 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 data protection software.
A single SAN24B-4 Express switch can serve as the cornerstone of a Storage Area Network 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 an 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 sixteen and twenty-four 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 six to twenty-two servers, each with dual Fibre Channel 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 BM 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.
