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
- New levels of performance with 8 Gigabits per second (Gbps) Fibre Channel (FC) technology
- Ports on Demand scalability from 8 to 16 to 24 ports
- Protection for 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 (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.
Common features
- 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)
Hardware summary
- 1U 19" packaging designed for rack-mount or table-top
- Designed for high performance with 8 Gbps FC ports (requires storage hardware that supports 8 Gbps throughput)
- Speed auto-sensing capabilities provide backward compatibility with 4, 2 and 1 Gbps FC links
- Supports 8, 4 and 2 Gbps link speeds or 4, 2 and 1 Gbps link speeds depending on which small form factor pluggable (SFP) optical transceivers 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 unauthorised 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 Graphical User Interface (GUI), Simple Network Management Protocol (SNMP) and Telnet
