Abstract

The IBM 2026 TotalStorage SAN portfolio expands with the introduction of the IBM 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.

Model Abstract 2026-E12

The IBM 2026 SAN12M-1 entry switch Model E12 is designed to meet the needs of entry level SAN applications, first-time SAN deployments, departmental SANs, and application specific deployments. The SAN12M-1 entry switch offers 4, 8, or 12 non-blocking ports, providing 1 and 2 Gbps Fibre Channel ports utilizing 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 disaster tolerance solutions.

Model Abstract 2026-224

The IBM 2026 SAN24M-1 mid-range switch Model 224 is designed to provide storage consolidation, high availability, and high-port density in a 1-U rack mount chassis. The SAN24M-1 supports both long-wave and short-wave 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 Fibre Channel, Arbitrated Loop (FC-AL), and Fabric (FC-SW). The SAN24M-1 is designed to provide integrated support for full Fabric and FC-AL tape attachment to SAN m-type family of enterprise directors and switches.

The SAN12M-1 entry switch includes one PDU jumper cord in the base, suitable for rack mount installation in the 2032-C40 cabinet. To order the correct country-specific power cord for the SAN24M-1 or SAN12M-1, specify the appropriate feature (#10xx).
Power cords - Model E12 and Model 224: One, and only one, country-specific power cord feature may be included in the order for each Model E12 and Model 224. To ensure you receive the correct country specific power cord, you must specify the power cord in your initial plant order. The Model E12 and Model 224 are equipped with one 110v US Power Cord, and one rack PDU jumper in the base configuration. In the U.S., all other U.S. power cord selections are completely optional. For example, if a U.S. 220v Power Cord is desired, there are various optional U.S. feature numbers to select from. For non-U.S. installations, appropriate power cord selection is required. If the Model E12 and Model 224 are not being installed in the U.S., you must choose the appropriate power cord for the country the machine will be installed in.
