Data compression is performed by using the hardware that is dedicated to data compression. The compression accelerator module operates on up to 32K at a time. In particular, the larger the I/O data size, the better the I/O performance.
Even if the data is compressed with software, the data can be converted to the data compressed by using the compression accelerator feature.
VSP One B24 does not have compression accelerator. VSP One B26 and VSP One B28 use compression accelerator by default, with optional deduplication on a general-purpose processor.
