Broadcom PCI Express Switches SS26-0B00-00 Managed PCI Express 5.0 Switches

SS26-0B00-00 is PCle Gen 5.0 (32 GT/s) switches, allowing customers to build systems from simple PCle connectivity inside the box to high-performance, low-latency, scalable, cost-effective PCle fabrics for composable hyper-scale compute systems supporting ML /AI and Server/Storage applications.

The SS26-0B00-00 switches offer up to 1024 Gb/s (128 GB/s) raw bandwidth per port (x16). The largest PEX89000 switch with 144 PCle Gen 5.0 lanes allows user to achieve up to 9,216 Tb/s (1,152 GB/s) of raw bandwidth through the device.

The SS26-0B00-00 switch series enables designers to:
Create basic switch topologies at PCle 5.0 rate (32 GT/s) to connect Hosts/CPUs to I/Os and peripherals in server and storage systems.
Create cost-effective high-availability hyper-scale systems by enabling communication between in-rack hosts and endpoints using PCle.
Simplify connectivity while providing the highest PCle switching performance available for data center servers, storage, and networks.
Reduce latency, system complexity, and power consumption in data-intensive environments.
Take advantage of industry-first features for most demanding hyper- converged, AI/ML/DL applications.
