Device Overview

The IBM SAN128B-7 offers the following features and capabilities:
  • Up to 128 ports in a 2U switch.
    • Up to 96 auto-sensing ports supporting high-performance 64G small form-factor pluggable plus (SFP+) transceiver port technology in a single domain with non-volatile memory express (NVMe) support from the host to the switch port on ingress and from the switch port to the target on egress.
    • Up to 16 double density (DD) ports or SFP+ ports supporting 64G Fibre Channel speed. Each DD port is capable of 2 x 64G ports, thus providing an additional 32 ports at 64G.
  • 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 SFP-DD POD).
  • 8, 10, 16, 32, and 64G auto-sensing Fibre Channel switch and router ports.
    • A 64G optical transceiver can auto-negotiate to 64G, 32G, or 16G.
    • A 32G optical transceiver can auto-negotiate to 32G, 16G, or 8G.
    • A 10G optical transceiver can auto-negotiate to 10G.
    Note: The port speed is determined by the maximum negotiated speed between the installed transceiver and the optical transceiver at the other end of the link, including any user-configured maximum or fixed speed.
  • Universal ports that self-configure as E_Ports, F_Ports, D_Ports, or EX_Ports and can be activated on a per-port basis with the optional Integrated Routing (IR) license. The Diagnostic D_Port mode provides diagnostics, troubleshooting, and verification services for the physical media.
  • Brocade small form-factor pluggable plus (SFP+) optical transceivers that support any combination of short wavelength (SWL), long wavelength (LWL), or extended long wavelength (ELWL) optical media among the switch ports.
  • LEDs:
    • 96 bicolor (green/amber) LEDs to indicate the status for each SFP+ port and 16 tricolor (green/amber/white) LEDs to indicate the status for each SFP-DD port.
    • One green LED to indicate valid system power.
    • One bicolor (green/amber) LED to indicate the system status.
    • Two Ethernet LEDs: one green LED to indicate link speed at 1000/100/10Mb/s and one green LED to indicate activity.
  • Hardware-enabled input and output (I/O) latency statistics collection.
  • Hardware-enabled VM support.
  • Extended distance Fibre Channel to support long-distance native FC connectivity.
  • A high-performance C3338R processor with two cores operating at 1.8 GHz that delivers high performance, scalability, and advanced Fabric Vision® functionality.
  • One embedded universal serial bus (e-USB) module that provides 4 GB of persistent storage, increased serviceability, and error logging functionality by facilitating easier firmware upgrades and downloads of the system log files.
  • Two hot-swappable redundant power supply FRUs.
  • Three hot-swappable redundant fan assembly FRUs.
  • Support for nonport-side intake or nonport-side exhaust airflow for cooling.
  • Serial electrically erasable programmable read-only memory (SEEPROM) for switch identification.
  • Secure boot.
  • Real-time power monitoring, voltage monitoring, and fan monitoring, including airflow direction.
  • Real-time digital thermometers for temperature monitoring.
  • Real-time clock (RTC) with battery.
  • Connectors:
    • One 10/100/1000Mb/s RJ-45 Ethernet connector for the management connection. 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.
    • One RS-232 3-wire (Tx, Rx, and GND) universal asynchronous receiver/transmitter (UART) serial port to the baseboard management controller (BMC) with an RJ-45 connector for debugging the initial switch setup (if not using EZSwitchSetup) and factory default restoration. Integral LEDs remain unlit always.
    • One external USB Type A connector.
