Cell Storage Processes
There are three processes will be running on the cell stoarge servers.
cellsrv - Cell Server
It is mutlithreaded process. The primary storage software components. Responsible for disk I/O with the use of iDB protocol.It communicates with Oracle Database to serve simple block requests like database buffer cache reads and Sart Scan requests like tablespaces with projections and filters. CELLSRV also implements I/ORM and collect statistics relating to its operation
MS - Management Server
This is the intermediater between command line interface and cell storage. It provide the interface of storage for configuration and administration purpose. It works with cellcli.It is also responsible to send alerts and collect statistics.
RS - Restart Server
Restart service will monitor the cellsrv and MS processes. It restarts them if necessary.
