Lenovo B300 FC SAN Switch
Product Guide
The Lenovo B300 FC SAN Switch (Machine Type 3873) provides small to medium-sized enterprises with Storage Area Network (SAN) connectivity that simplifies their IT management infrastructures, improves system performance, maximizes the value of virtual server deployments, and reduces overall storage costs.
The Lenovo B300 is a 1U rack-mount 8 Gb Fibre Channel switch with up to 24 ports (8 ports licensed by default; the remaining ports can be licensed in 8-port increments) that support 2/4/8 Gbps speeds. The switch offers a rich set of standard software features with the options to expand its capabilities as needed.
The Lenovo B300 features the EZSwitchSetup wizard and can be configured in Access Gateway Mode to simplify deployment. The switch provides full non-blocking performance with Ports On Demand scalability to support SAN expansion and enable long-term investment protection.
The following figure shows the Lenovo B300.

Software
The Lenovo B300 comes standard with the following software features:
Advanced Fabric Services
Full Fabric mode (standalone): Enables high performance 8 Gb switching in singleswitch fabric.
Advanced Zoning (default zoning, port/WWN zoning, broadcast zoning)
Dynamic fabric provisioning (DFP): Fabric-assigned port World Wide Names (FA-PWWNs).
Dynamic path selection (DPS): Distributes input traffic across multiple paths proportionally to the bandwidth of each path.
Dynamic load sharing (DLS): Distributes traffic across multiple equivalent paths between switches.
Fabric Shortest Path First (FSPF)
Buffer-to-Buffer (BB) credit flow control
Enhanced BB credit loss recovery
Fabric Device Management Interface (FDMI)
Frame order delivery
Frame redirection
FC login services
Registered State Change Notification (RSCN)
Reliable Commit Service (RCS)
Simple Name Server (SNS)
Fibre Channel Authentication Protocol (FCAP) switch authentication
Management Server (MS): Assists in the auto-discovery of switch-based fabrics.
Adaptive Networking
Bottleneck detection: Identifies devices attached to the fabric that are slowing down traffic.
Ingress rate limiting: Restricts the speed of traffic from a particular device to the switch port.
Traffic isolation zoning (TIZ): Creates a dedicated path for traffic flowing from a specific set of source ports (F_Ports).
Quality of Service (QoS): SID/DID traffic prioritization
Virtualization
N_Port ID virtualization (NPIV): Enables a single FC port to appear as multiple, distinct ports with separate port identification within the fabric.
Access Gateway (requires all 24 ports be licensed): Leverages NPIV to connect to any fabric without adding switch domains to reduce management complexity.
