With the increasing of data, the frequency of using computer to process data is growing much more than before. Therefore, decreasing data capacity is becoming one of the most important issues to reduce cost. During these years, SATA disk is the most cost effective solution to provide storage capacity. However, Cavium Octeon is an embedded system, which is no SATA disk installed. An analysis of Linux Kernel for installing SATA disk is presented for better storage capacity before data compression. There are two ways for data compression, loss compression and lossless compression. Loss compression is usually utilized in image, video and audio processing, as well as lossless compression is usually used for text compression or the environment of low fault-tolerant compression. Cavium Octeon provides a hardware lossless compression solution called zip Coprocessor which is implemented in this research. After the implementation, data compressed by zip Coprocessor can be decompressed by gzip, and the result is same vice versa.
