Products: fastt and ds4000Host platform: P/I/z/X-series, sun, HP ,...Operating System: Aix, Sun Solaris, HP-UX, Linux You can use the fastt Storage Manager tool to set different cache parameters. The setting of these parameters directly affects the performance and data availability of the fastt storage server. The following describes these parameters.Cache memory

IBM totalstorageThe ds4000 series is a storage product launched by IBM for medium-sized enterprises. It was upgraded from the fastt series and has enhanced some storage functions. Its products are composed of ds4100 (originalFastt100) to ds4500 (formerly fastt900) can meet most of the storage needs from the low-end to the middle-end, and provide enterprises with comprehensive products and services at reasonable costs.It has been widely used in the Chi

) of the fastt Logical Disk is very important to system performance. For large fastt configurations, many volumes are connected to the host. This setting is more critical for high reliability. The queue depth is too large, leading to file system loss or host crashes. The following describes how to correctly set the disk queue depth and its calculation method. We can use the
