What is the performance latency of this switch?

Fabric latency is 700 ns with no contention using cut-through routing at 16Gb/s. It supports full duplex line speeds up to 16.025Gb/s, jumbo frames to 9216 bytes, and features like WAN-optimized TCP and adaptive rate limiting for efficient long-distance storage traffic.

Is the Brocade 7840 rack-mountable?

Yes, it is a 2U rack-mountable chassis designed for 19-inch EIA-compliant cabinets with back-to-front airflow. Weighing 5.00 lbs, it includes redundant PSUs and 3 fan modules for reliable operation in enterprise data centers.

What scalability does it offer?

Supports full fabric architecture up to 239 switches, single fabric with 56 domains/7 hops, or multiprotocol routing with 19 hops. Ideal for large SAN environments requiring high port density and extension capabilities.

Does it support data encryption over distance?

Yes, it encrypts storage data flows at full line rate without performance penalty using Brocade Gen 5 technology. Includes advanced compression and FCIP FastWrite for secure, efficient data center interconnects and disaster recovery.

What management features are available?

Manageable via Brocade Fabric Vision for performance monitoring, security, and diagnostics. Supports Layer 2 standards, optical fiber media, and 10GBase-X technology with classes of service including Class 2/3/F.
