• MDS 9124 switches have fixed configurations with 8, 16, and 24 full-rate 4 Gb/s Fibre Channel ports. The 8 and 16-port switches can be upgraded in 8-port increments with a software expansion license. • MDS 9124e 12-port Fabric switch and the MDS 9124e 24-port Fabric switch for the c-Class BladeSystem have fixed configurations with 8 internal/4 external or 16 internal/8 external fullrate 4 Gb/s Fibre Channel ports. The 12-port switch can be upgraded to a 24-port switch with a software expansion license. • MDS 9020/9120/9140 switches have fixed configurations with 20 and 40 Fibre Channel ports, respectively: • MDS 9120 has 4 full-rate Fibre Channel ports and 16 2 Gb/s oversubscribed ports. • MDS 9140 has 8 full-rate Fibre Channel ports and 32 2 Gb/s oversubscribed ports. • MDS 9020 has a fixed configuration with 20 full-rate 4 Gb/s Fibre Channel ports. • C-series Fibre Channel switches are supported for use with FCIP through the HP IP Distance Gateway. (See "SAN extension" on page 279 for more information.) The C-series Fibre Channel switches offer: • High availability • Scalability • Cost efficiency Model naming The C-series Fibre Channel switches are named MDS 9xnn. The 95nn switches (Multilayer Directors) are director or core switches. The nn value indicates the number of slots available for supervisors and port modules. The 92nn switches are mid-range switches; the 91nn switches are entry-level switches; the MDS 9020 switch is an entry-level 4 Gb/s switch (Multilayer Fabric switches). For the 92nn, 91nn, and 90nn, the nn value indicates the number of fixed ports. Multiprotocol and Multiservice products are designated with the i suffix, such as the MDS 9216i and MDS 9222i, or as IP storage services modules, such as the IPS-4, IPS-8, 14/2, and 18/4. For IPS products, the number indicates the total number of IP ports available. For example, the IPS-4 has 4 IP ports and the IPS-8 has 8 IP ports. Switch models NOTE: Starting with release 4.1(1b), MDS 9000 SAN-OS software is rebranded to MDS 9000 NX-OS software. Software prior to NX-OS 4.1(1b) uses the SAN-OS name and remains on the 3.x code stream. NX-OS is designed to operate with switches running SAN-OS software. Table 41 and Table 42 describe the C-series Fibre Channel switches, and Table 43 describes the legacy C-series Fibre Channel switches. HP supports all C-series Fibre Channel switches in a fabric if you: • Use the firmware versions listed in Table 41, Table 42, and Table 43. When using NX-OS, SAN-OS, and FabricWare in the same fabric, HP strongly recommends upgrading all fabric switches in the SAN to the latest supported software version. All switches in the same major NX-OS/SAN-OS/FabricWare family must use the same software version. When up- SAN Design Reference Guide 137
