Alcatel ALE OmniSwitch OS6900X24-R-EU

For data centers and enterprise cores where every microsecond counts, the Alcatel-Lucent OmniSwitch OS6900X24-R-EU pairs 1.28 Tbps of switching capacity with a rear-to-front airflow design that aligns perfectly with hot-aisle containment. Its 24 SFP+ ports deliver wire-speed 10 Gigabit Ethernet, while optional uplink modules scale the fabric to 40GbE without a chassis swap.

Highlights

• 24 × 1/10G SFP+ ports with sub-microsecond latency for latency-sensitive applications
• Rear-to-front airflow (R-to-F) optimized for data center cold aisle/hot aisle layouts
• Modular uplink options: dual 40GbE QSFP+ or eight additional 10GbE SFP+
• Advanced Layer 3 routing: OSPF, BGP, VRRP, PIM, and 128K IPv4 routes
• Virtual Chassis stacking for up to eight units as a single logical switch
• Redundant hot-swappable AC power supplies and 250,000-hour MTBF

In daily use

Deploy the OS6900X24-R-EU as a top-of-rack switch in high-density server environments. Its 1U form factor conserves rack space, while the rear-to-front cooling pulls air from the cold aisle across the line cards and exhausts into the hot aisle—reducing cooling costs and preventing thermal recirculation. The 960 Mpps forwarding rate ensures line-rate performance even with jumbo frames up to 9216 bytes, and the 128K MAC address table handles large virtualized workloads without flooding. Stack up to eight switches via Virtual Chassis to manage a 192-port fabric from a single IP address, simplifying operations and enabling cross-stack link aggregation.
