 IBM System Storage SAN24B-4 Express
Designed for high-performance, scalability and simple-to-use in small to medium-size SAN environments
| | |
- 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.

Hardware summary |
|
- Standard configuration includes 8-port activation and capability to attach to hosts and storage device. Capability to attach to other SAN devices is standard on 2498-B24 and optional on 249824E.
- Eight-port activation option enables “pay-as-you-grow” scalability to 16 and 24 ports.
- No previous SAN experience needed to use EZSwitchSetup wizard.
- Little or no management required in small fabric configuration.
- Advanced Web Tools provides intuitive, graphic switch management.
- Supports IBM POWER Systems and System x, plus selected non-IBM servers.
- Full compatibility with other IBM System Storage and TotalStorage SAN b-type switches, routers and directors and Native Interoperability with current m-type switches and directors helps protect prior SAN investments.
- Ideal for use as an edge switch in larger SANs.
- Access Gateway mode enables seamless connectivity into heterogeneous SAN environments, enhances scalability and simplifies manageability (available only on 24-port configurations).

- 1U 19" packaging designed for rack-mount or table-top.
- Designed for high-performance with 8 Gigabit per second (Gbps) fibre channel ports (requires storage hardware that supports 8 Gbps throughput).
- Speed auto-sensing capabilities provide backward compatibility with 4, 2 and 1 Gbps fibre channel links.
- Supports 8, 4 and 2 Gbps link speeds or 4, 2 and 1 Gbps link speeds depending on which optical transceivers (SFPs) are used.
- Shortwave and longwave SFPs with different speeds can be intermixed in the same switch to meet unique requirements.
- Full Fabric operation and Universal Port Operation are available on all ports.
- Inter Switch Link (ISL) trunking is supported on all ports.
- Advanced Zoning, intelligent management and monitoring with Web Tools, Fabric Watch and Performance Monitor features.
- Non-blocking architecture designed to provide up to 284 Gbps aggregate throughput with a 24-port configuration.
- Standard Advanced Zoning provides hardware-enforced zoning to protect against unauthorized or unauthenticated storage network access, non-secure management access and World Wide Name spoofing.
- IBM SAN b-type switches and directors use common switch firmware, which helps simplify SAN fabric expansion.
- Firmware upgrades are designed to be non-disruptive.
- Remote access and remote management are available through the fabric using GUI, SNMP and Telnet.
