Identify three Exadata Storage Server software processes and their purpose?

Question

Options

• ACELLSRV: The Cell Server is responsible for servicing disk I/O and predicate processing offload.
• BCELLSRV: The Cell Server is responsible for balancing workload to other storage servers.
• CMS: The Management Server is responsible for storage cell management and configuration.
• DMS: The Management Server is responsible for starting a local Enterprise Manager agent.
• ERS: The Restart Server is responsible for Automatic Storage Management (ASM) instance
• FRS: The Restart Server is responsible for CELLSRV and MS monitoring and restart.

Explanation

A: CELLSRV (Cell Services) is the primary component of the Exadata software running in the cell and provides the majority of Exadata storage services. CELLSRV is multi-threaded software that communicates with the database instance on the database server, and serves blocks to based on the iDB protocol. It provides the advanced SQL offload capabilities, serves Oracle blocks when SQL offload processing is not possible, and implements the DBRM I/O resource management functionality to meter out I/O bandwidth to the various databases and consumer groups issuing I/O. C: The MS is the primary interface to administer, manage and query the status of the Exadata cell. It works in cooperation with the Exadata cell command line interface (CLI) and EM Exadata plug-in, and provides standalone Exadata cell management and configuration. For example, from the cell, CLI commands are issued to configure storage, query I/O statistics and restart the cell. Also supplied is a distributed CLI so commands can be sent to multiple cells to ease management across cells. F: Restart Server (RS) ensures the ongoing functioning of the Exadata software and services. It is used to update the Exadata software. It also ensures storage services are started and running, and services are restarted when required.
