This section describes “IBM 48 port 32 Gbps Fibre Channel Switching Module” on page 32 supported
by the IBM c-type SAN director switches.
IBM 48 port 32 Gbps Fibre Channel Switching Module
The IBM 48 port 32 Gbps Fibre Channel switching module is designed specifically for the IBM c-type SAN
directors.
With 768 line-rate 32 Gbps Fibre Channel ports per director, the 32 Gbps 48 port Fibre Channel switching
module meets the high-performance needs for flash-memory and Non-Volatile Memory Express (NVMe)
over Fibre Channel workloads. The switching module is hot swappable and compatible with 4 Gbps,
8 Gbps, 16 Gbps, and 32 Gbps Fibre Channel interfaces. This module also supports hot swappable
Enhanced Small Form-Factor Pluggable (SFP+) transceivers.
Individual ports can be configured with 32 Gbps, 16 Gbps, 8 Gbps and 4 Gbps SFP+ transceivers. Each
port supports 500 buffer credits for exceptional extensibility without the need for additional licenses.
With the Enterprise Package license, up to 8191 buffer credits can be allocated to an individual port,
enabling full link bandwidth over long distances with no degradation in link utilization.
Figure 13 on page 32 shows the IBM 48 port 32 Gbps Fibre Channel Switching Module.
