Industry's first SATA RoC
Single-chip solution integrates:
• 8-ports of SATA including high-performance 1.5G PHY
• 266-MHz MIPS
• Memory controller with QDMA™ engine
• XOR engine for RAID5 hardware assist
• Enterprise-class RAID stack
Host interfaces
• PCI-X 1.0; PCI Express™ (x4)
• PCI-E → PCI-X bridge
High-performance QDMA™ engine lowers CPU utilization,
increases IOPS and throughput
• 256 independent command queue entries per port
• Advanced interrupt coalescing algorithms
Automatic status block update
• Decrease CPU utilization, increase efficiency of PCI-X bus
Integrated BERT generator and monitor
Native Command Queuing (NCQ)
Hot plug support

... PCI-E and PCI-X interfaces enables extra PCI-X slots to be available for I/O expansion when the PCI-E interface is used as a host interface to the BCM5773. It attaches directly to eight SATA- II disk drive backplanes via a high-performance, integrated SATA PHY that is capable of driving long-length backplanes. Hot-Plug capability is also supported, enabling drives to be inserted/removed without affecting system operation ...
