®
Broadcom PS225 SmartNIC adapters, based on Broadcom's latest data center SoC technology, offer groundbreaking
network and compute power in a compact package. The PS225 adapters are PCI Express low-profile, half-length adapters,
and provide two 25-Gigabit Ethernet (25GbE) ports along with eight 64-bit ARMv8 processors running at an unmatched
3.0 GHz clock rate. The adapters are available in a range of on-board DDR4 memory sizes. The PS225-H04, PS225-H08,
and PS225-H16 adapters include 4 GB, 8 GB, and 16 GB of DDR4 memory, respectively.
