To communicate outside of the chassis, you must have either SFP+ transceivers or SFP+
direct-attach copper (DAC) cables connected. DAC cables have SFP+ transceivers on both
ends. You have the flexibility to expand your bandwidth, using anywhere from one connection
up to 10 connections per switch.
IBM Virtual Fabric 10Gb Switch Module features and functions
The IBM Virtual Fabric 10Gb Switch Module includes the following features and functions:
򐂰 Form-factor: Single-height, high-speed switch module
򐂰 Internal ports:
– Fourteen internal auto-negotiating ports: 1 Gbps or 10 Gbps to the server blades.
– Two internal, full-duplex 100Mbps ports connected to the management module.
򐂰 External ports:
– Up to ten 10 Gb SFP+ ports (also designed to support 1 Gb SFP if required, with the
flexibility to mix 1 Gb/10 Gb). The oversubscription ratio (14 internal ports to
10 external ports) is low, which makes the switch module suitable for the most
performance-intensive environments
– One 10/100/1000 Mb copper RJ45 that is used for management or data.
– An RS-232 mini-USB connector for serial port that provides an additional means to
install software and configure the switch module. This USB-style connector enables
connection of a special serial cable that is supplied with the switch module.
򐂰 Scalability and performance:
– Autosensing 1 Gb/10 Gb internal and external Ethernet ports for
bandwidth optimization.
– Non-blocking architecture with wire-speed forwarding of traffic and full line rate
performance of 480 Gbps full duplex.
– Media access control (MAC) address learning: Automatic updates, and supports up to
32 Kb MAC addresses.
– Up to 128 IP interfaces per switch.
– Static, EtherChannel, and Link Aggregation Control Protocol (LACP) (IEEE 802.3ad)
link aggregation, up to 100 Gb of total bandwidth per switch, up to 18 trunk groups, and
up to eight ports per group.
– Support for jumbo frames (up to 12288 bytes).
– Broadcast and multicast storm control.
– IGMP snooping for limit flooding of IP multicast traffic (IGMP V1, V2, and V3).
– Configurable traffic distribution schemes over trunk links, based on source and
destination IP addresses, MAC addresses, or both.
– Fast port forwarding and fast uplink convergence for rapid Spanning Tree Protocol
(STP) convergence.
– Stacking support: Clients can stack up to eight IBM Virtual Fabric 10Gb Switch Module.
Transceivers: Small form-factor pluggable plus (SFP+) transceivers are not included in
the purchase of the switch. All 1/10 Gb transceivers require LC-to-LC cables.
