IWEB .0001 In Line Data Compression: Ranges from 1.2 to 3.8x compression
To optimize the use of valuable data storage resources, data must be compressed when written to an array and then uncompressed when read. IceWEB’s Unified Data Storage Systems are designed to rapidly process these read-write compressions and decompressions by incorporating high-speed processors and an innovative cache design to ensure that using compression does not add significant overhead to I/O operations.
In addition, for blocks of data that are not very compressible — that is, the compression algorithm does not result in significant space savings — the system automatically skips compression for that data stream. This unique capability maximizes the efficiency of I/O throughput by simply avoiding attempts to compress and decompress dense blocks of data with minimal compression ability.
For blocks of data that do compress, we can eliminate I/Os, thus not only saving you capacity, but also reducing the overall I/O load on the system resulting in an overall performance increase for your array. Given all of this, there really is no reason not to be using compression for all your data; there is minimal downside, and a very significant upside with most applications.
