Highlights

A 1U, high-density top-of-rack data center switch for 10 GbE server access and aggregation with twenty-four 10 GbE/1 GbE dual-speed (SFP+) ports plus four 10/100/1000 MbE (RJ45) ports
Flexibility to mix 10 GbE and 1 GbE servers, protecting investments and streamlining migration to 10 GbE-capable server farms
Wire-speed performance with an ultra-low-latency, cut-through, non-blocking architecture that is ideal for HPC environments
Highly efficient power and cooling with front-to-back airflow, automatic fan speed adjustment, and use of SFP+ and direct attached SFP+ copper (Twinax) for maximum flexibility
High availability with redundant, load-sharing, hot-swappable, auto-sensing/switching power supplies and a resilient triple-fan assembly
End-to-end Quality of Service (QoS) with hardware-based marking, queuing, and congestion management
Embedded per-port sFlow capabilities to support scalable hardware-based traffic monitoring

The IBM® Ethernet Switch B24X is a compact, high-performance, high-availability, and high-density 1 RU switch specifically designed for mission-critical data centers and High-Performance Computer (HPC) requirements. This switch provides twenty-four 10/1 GbE (SFP+) ports plus four 10/100/1000 MbE (RJ45) ports of connectivity in an ultra-low-latency, cut-through, non-blocking architecture.

This switch is an ideal cost-effective solution for server or compute-node connectivity. 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 switch can be positioned as a 10 GbE aggregation switch behind 1 GbE access switches.
