Device Overview
The IBM SAN128B-6 offers the following features and capabilities:
v Up to 96 auto-sensing ports supporting high-performance 32-Gbps SFP+ ports technology in a single
domain with NVMe support on egress-only.
v Up to eight auto-sensing 128-Gbps (4 x 32-Gbps) QSFP ports to connect to the QSFP ports of other
devices or F_Ports.
v Dynamic Ports on Demand (Dynamic-POD) scaling from a base configuration of 48 ports to 128 ports
(two 24-port SFP+ PODs and one 32-port QSFP POD).
v 4-, 8-, 16-, and 32-Gbps auto-sensing Fibre Channel switch and router ports.
– A 32-Gbps optical transceiver can auto-negotiate to 32 Gbps, 16 Gbps, or 8 Gbps.
– A 16-Gbps optical transceiver can auto-negotiate to 16 Gbps, 8 Gbps, or 4 Gbps.
– A 10-Gbps FC optical transceiver can support 10 Gbps speed.
Note: The port speed is determined by the maximum speed supported by the optical transceiver at the
other end of the link.
v Universal ports self-configure as a E_Ports, F_Ports, or D_Ports. EX_Ports can be activated on a
per-port basis with the optional Integrated Routing license.
– Diagnostic D_Port mode provides diagnostics, troubleshooting, and verification services for the
physical media.
v Up to 384 Gbps of combined in-flight data encryption/decryption and 192 Gbps of combined in-flight
compression/decompression capabilities per switch.
v Dynamic buffer sharing
v Support for nonport-side intake or nonport-side exhaust airflow for cooling.
v Hardware-enabled input and output (I/O) latency statistics collection.
v Hardware-enabled VM support.
v Brocade small form-factor pluggable plus (SFP+) optical transceivers support any combination of Short
Wavelength (SWL), Long Wavelength (LWL) or Extended Long Wavelength (ELWL) optical media
among the switch ports.
v Extended distance Fibre Channel to support long distance native FC connectivity.
v Port-to-port latency is minimized to 900 nanoseconds (including FEC) by using cut-through frame
switching at 32 Gbps.
v High performance T1042E processor with four cores operating at 1.5 GHz delivers high performance,
scalability, and advanced Fabric Vision functionality.
v One 10/100/1000 Mbps RJ45 connector Ethernet port for management connection. In conjunction with
EZSwitchSetup, this port supports switch IP address discovery and configuration, eliminating the need
to attach a serial cable to configure the switch IP address.
v One RS-232 3-wire (Tx, Rx, and Gnd) universal asynchronous receiver/transmitter (UART) serial port
to BMC with RJ-45 connector for debugging initial switch setup (if not using EZSwitchSetup) and
factory default restoration. Integral LEDs remain unlit at all times.
v One internal e-USB module provides 2 GB of persistent storage, increased serviceability, and error
logging functionality by facilitating easier firmware upgrades and downloads of the system log files.
v One external USB Type A connector.
v Two hot-swappable redundant power supply field-replaceable units.
v Three hot-swappable redundant fan assembly field-replaceable units.
v 128 bicolor (green/amber) LEDs to indicate the status for each port.
