HyperTransport™ SystemI/O Controller with PCI Express® and SAS/SATA I/O
The HT-1100 is targeted at the volume server/blade and workstation market with the capability to efficiently span from 1-8 socket CPUs without incurring large latencies.
The HT-1100 is a highly scalable SystemI/O solution for 64-bit/32-bit processors that can be configured to meet OEM's needs for a variety of product segments. The dual-socket configuration shown on the product brief uses the HT-2100 as a tunnel to the processors. By combining the HT-1100 with the HT-2100, servers can support up to seven PCI Express Gen1 masters for a total of 32 PCI Express links. However, the HT-1100 can be used to directly connect to the processors, as shown in the upper right graphic. This allows a lower latency path to the processors and memory.
The 8x HT port can operate up to 1-GHz double data rate in both transmit and receive directions to aggregate up to a total bandwidth of 4 GBps. It is also backward-compatible to slower HyperTransport speeds.
