IBM Ethernet Switch B24X

IBM System x at-a-glance guide

The IBM Ethernet Switch B24X is a compact, high-performance, high-availability, and high-density 10
GbE solution that meets mission-critical data center and High Performance Computer (HPC)
requirements. It can support 1 GbE servers until they are upgraded to 10 GbE-capable Network Interface
Cards (NICs), simplifying migration to 10 GbE server farms.
In addition, the B24X is a fully featured switch with IPv4 Layer 3 capabilities that can provide cost-efficient
10 GbE network aggregation for 1 GbE access switches. The switch runs a feature-rich and mature
IronWare Operating System with an industry-standard command-line interface (CLI), minimizing
re-training and operational costs. Supporting a full range of Request for Comments (RFC) and Institute of
Electrical and Electronics Engineers (IEEE) standards for interoperability, along with compatibility for
vendor-specific protocols such as Cisco Discovery Protocol (CDP) and Per-VLAN Rapid Spanning Tree
Plus (PVRST+), the B24X integrates seamlessly into existing network infrastructures.

Did you know

The IBM Ethernet Switch B24X is the most power-efficient 10 Gbps switch in its class at 176 watts per
twenty-four 10 GbE ports. This saves customers up to 56% in power and cooling costs over competing
switches. In addition, the high-performance, cut-through, full-mesh non-oversubscribed (1:1) architecture
of the B24X offers up to twice the performance with lower latencies and uses up to 2 - 3 times less rack
The no-compromise B24X also features data center class network resiliency and hardware availability
features to support non-stop networking, making the switch ideal as an all-purpose Top of Rack switch
