Lossless data compression can be valuable in any number of storage, server, and networking situations, reducing both required bandwidth and storage space without damaging the data. It's too laborious to achieve high throughput in software using the Lempel-Ziv-type algorithms necessary for good compression ratios. One vendor, Comtech AHA Corp (www.aha.com), plans to offer a drop-in PCIe (PCI Express) card as a hardware accelerator for the open-source gzip (GNU-zip) algorithm. The board will be available in the first quarter of 2008, but the company offered EDN an early look at what it takes to accelerate gzip.
