What ports does the IBM BN-8000F-F support?

It includes 44 auto-sensing 10/100/1000Mb Ethernet RJ-45 ports and four SFP ports for 1GbE transceivers (1000BASE-SX/LX/T). Optional uplinks add up to four SFP/SFP+ for 1/10GbE (10GBASE-SR/LR/ER or DAC), with modules purchased separately for enterprise flexibility.

What is the switching performance of this switch?

Delivers 176Gbps full-duplex throughput in non-blocking mode across all ports, with <3μs latency at line-rate. Supports 16,000 MAC addresses, jumbo frames up to 9,216 bytes, and 52 LACP trunks (8 ports each) for high-performance data center applications.

Is the BN-8000F-F suitable for virtualization?

Yes, with vLAG support, up to 1024 VLANs (1-4094), IGMP snooping, and private VLANs to manage multicast and segment traffic efficiently. Non-blocking 176Gbps capacity handles massive VM workloads without oversubscription.

What are the physical and environmental specs?

1U rack-mount (1.75in H x 17.3in W x 15.0in D, 11.99lbs) with redundant PSU/fans and front-to-rear cooling. Operates 32-113°F (0-45°C), 10-85% humidity, up to 10,000ft altitude; power 116-170W, noise <65dB.

Does it support redundancy and high availability?

Features redundant power supplies and fans, plus high-availability protocols like LACP, storm control, and 802.1x. Designed for always-on business traffic in IBM System x/iDataPlex environments with minimal downtime.

What cooling and power options are available?

F model offers front-to-rear cooling with AC redundant PSUs (116-170W typical). Compatible with rack kits for iDataPlex; select models support DC power, ensuring reliability in dense, hot-aisle data centers.
