GZIP, an Open Source lossless data compression algorithm and file format, is a commonly used data compression algorithm based on LZ1. GZIP data compression is widely used in Storage applications such as Virtual Tape Libraries (VTLs) and Network Attached Storage (NAS) appliances. GZIP is embedded natively in most Internet Web Browsers.
Virtual Tape Libraries, Network Attached Storage appliances, and other storage systems that implement the AHA363-PCIe GZIP compression decompression board are benefiting from the improved compression performance that is better than previously used algorithms like ALDC and LZS. When compared against software based GZIP compression, the AHA363-PCIe board results in higher throughput up to 5 Gigabits per second and lower power consumption since it uses the AHA3610 GZIP/DEFLATE compression decompression coprocessor ASIC. This offloading of the compression task to a coprocessor also saves valuable CPU cycles that can be used for other tasks
The AHA3610, AHA363-PCIe, AHA364-PCIe, and AHA367-PCIeimplement the GZIP data compression algorithm.
Tape backup systems of various types have been using lossless data compression for many years to increase the capacity of the tape drives by between 1.5 and 2.5 times. AHA sells standard hardware that implements the Adaptive Lossless Data Compression (ALDC) algorithm. Both QIC and AIT drives use the ALDC algorithm. The AHA35xx devices implement the ALDC compression algorithm.
