Switches can be scaled into complex SANs.
Press Release Summary:
TotalStorage® SAN24M-1 mid-range switch supports longwave and shortwave transceivers, and offers up to 24 non-blocking ports in 8-port increments, with auto-sensing and auto-rate-negotiation support for 1 and 2 Gb/sec FC-AL and Fabric (FC-SW). TotalStorage SAN12M-1 entry switch offers 4, 8, or 12 non-blocking ports, providing 1 and 2 Gbps Fibre Channel ports that use auto-sensing and auto-rate-negotiating operation with Fabric and Public Loop attached devices.
Original Press Release:
IBM TotalStorage SAN Portfolio Expands with a SAN24M-1 Mid-Range Switch and a SAN12M-1 Entry Switch for Infrastructure Simplification
Overview
The TotalStorage® SAN portfolio expands with the introduction of the TotalStorage SAN m-type family of mid-range and entry switch products.
They can be architected and scaled into complex enterprise SANs using a high-availability backbone director with fabric switches at the edge to support cost-effective and high-performance solutions.
The initial offering of the TotalStorage SAN m-type family of mid-range and entry switch products includes:
o IBM TotalStorage SAN24M-1 mid-range switch (2026-224)
o IBM TotalStorage SAN12M-1 entry switch (2026-E12)
The IBM TotalStorage SAN24M-1 mid-range switch offers storage consolidation, high-availability, and high-port density in a 1-U rack mount chassis. It supports longwave and shortwave transceivers, offers up to twenty-four non-blocking ports, in eight-port increments, with support for auto-sensing, auto-rate-negotiation 1 and 2 Gb/sec FC-AL and Fabric (FC-SW).
It helps you to purchase upgrades to connectivity when needed and integrates support for full-Fabric and FC-AL tape attachment to SAN m-type family of enterprise directors and switches.
The IBM TotalStorage SAN12M-1 entry switch addresses the needs of entry-level SAN applications, first-time SAN deployments,
departmental SANs, and application-specific deployments.
It offers 4, 8, or 12 non-blocking ports, providing 1 and 2 Gbps Fibre Channel ports that use industry standards-based auto-sensing and auto-rate-negotiating operation with Fabric and Public Loop attached devices.
The optional Full-Fabric Activation feature enables support for
Inter-Switch Link (ISL) and full bandwidth extended distance
operation up to 10 km at 2 Gbps (when configured with longwave
transceivers), to help support disaster tolerance solutions.
Support for some configurations may not be available on the initial availability date.
