The 2498-B24 is the IBM System Storage SAN24B-4, which IBM lists as the Brocade 300. It is aimed at medium-sized SANs, from a single switch to larger multi-switch fabrics, and as an entry-level eight-port consolidation switch it can serve up to seven servers with a single path to disk or tape.
Ports on Demand grows a base switch from 8 active ports to 16 and then 24 without taking it offline. One GoldenEye2 ASIC serves all 24 ports at 1, 2, 4 and 8 Gbps, with ports configurable as F, FL, E, M and EX, and subscription is 1:1 across the 24 ports. Standard configuration is an 8-port activation with the ability to attach to hosts and storage devices; attaching to other SAN devices is standard on the 2498-B24 and optional on the 249824E.
Fabric OS v6.1 or later is required. Frame-based trunking with up to eight 8 Gbps ports per ISL trunk, 64 Gbps per trunk, is an optional license, while exchange-based load balancing across ISLs with DPS is included in Fabric OS.
For a director-class b-type chassis, IBM's range includes the 2109-M48 SAN256B and the 2499-384 SAN768B.
