Computer Associates BrightStor Hierarchical Storage Manager (HSM) is an application used to create a tiered storage solution for enterprises that require on demand access to large quantities of data. The HSM caches frequently used files on hard drives for fast access, and stores seldom used files on tape. Access to files stored on tape is transparent to the client applications. The CsAgent process (CsAgent.exe) is a component of the HSM suite, and listens on TCP port 2000.
