What is the switch latency of this blade module?

Latency is under 2.1 microseconds port-to-port at 2 Gbit/sec with cut-through routing in a fully non-blocked multistage shared memory architecture. This ensures high-performance core switching for large SANs with aggregate 512 Gbit/sec bandwidth.

Does it support mainframe environments?

Yes, it provides FICON support for mainframe connectivity, compatible with open systems. Integrates into fabrics up to 239 switches, enabling reliable hybrid SANs with zoning and Brocade Fabric OS management.

What scalability options does the SilkWorm 24000 16-Port Blade offer?

Supports non-disruptive scaling from 32 to 128 ports in a single domain within a 14U chassis, up to 384 ports per rack. ISL Trunking delivers up to 8 Gbit/sec per trunk, interoperable with SilkWorm 2000/3000 series.

Is this blade future-proof for higher speeds?

The architecture supports upgrades to 4 Gbit/sec, 10 Gbit/sec Fibre Channel, and IP protocols like FCIP/iSCSI blades. This pay-as-you-grow design extends usability in evolving enterprise SANs.

What management features are included?

Brocade Fabric OS offers intelligent zoning, monitoring, and ISL Trunking. Redundant hot-pluggable components ensure high availability, with no single points of failure for mission-critical deployments.

Product overview

The Brocade SilkWorm 24000 16-Port Blade is an enterprise-level blade switch module designed for core-to-edge Storage Area Networks (SANs) in mission-critical environments. Part of the SilkWorm 24000 Director chassis, it supports up to 128 concurrently active 2 Gbit/sec full-duplex ports in a single domain, enabling non-disruptive scalability from 32 to 128 ports. Featuring a fully non-blocked architecture and multistage shared memory, it delivers switch latency under 2.1 microseconds for high-performance switching. ISL Trunking aggregates up to 8 Gbit/sec per trunk for enhanced bandwidth. Compatible with open systems and mainframes via FICON support, it integrates with Brocade Fabric OS for zoning, management, and interoperability across SilkWorm families. Ideal for large-scale fabrics up to 239 switches, it reduces latency, management costs, and power usage while future-proofing for 4 Gbit/sec and IP protocols. SKU: 60-1002121-04.
