5.0 Gbits/sec GZIP Compression/Decompression Accelerator
363 boardsmall with heat sink for web 0808 300x199 AHA363 PCIe

*Legacy Product - Not Recommended For New Designs

The AHA363-PCIe is a PCI-e plug in card that adds GZIP compression and decompression to data networking streams. This card supports data rates of over 5.0 gigabits per second. Communication and storage networks require high-speed compression solutions to provide low latency links. Compression also saves valuable media space when storing files to disk or tape.

The AHA363-PCIe is several times faster than the closest competitive solutions. The AHA363-PCIe is ideal for SAN servers, virtual tape emulation backup and recovery systems, point-to-point communication link servers and SSL accelerators. The AHA363-PCIe will improve the speed and performance for nearly any system requiring compression or decompression.
