Cell Server (CELLSRV) The CELLSRV process is the main kernel of Exadata Storage Server Software and is responsible for serving iDB requests initiated by the database and ASM instances The CELLSRV process handles simple block I/O requests along with offload processing requests The CELLSRV process implements IORM plans and performs throttling of I/O bandwidth based on I/O priorities as defined by the plan CELLSRV also interacts with DBRM for implementing intradatabase resource manager plans Management Server (MS) The MS process provides management and monitoring functions for the Exadata Storage Server Software The MS process is responsible for triggering alerts when exceptions are encountered by the Exadata Storage Server components The MS process communicates with CELLSRV and the operating system utilities in order to check the health of the software and hardware components Restart Server (RS) The RS process handles startup and shutdown requests of the Exadata Storage Server Software The RS process monitors the CELLSRV and MS process, and restarts them when they die abruptly There is also a backup RS process that takes care of restarting the primary RS process if the primary itself is not running CellCLI The Cell Command Line Interface (CellCLI) is the utility that you use to perform management and administration functions on the Exadata Storage Server Software More details on CellCLI are covered later in this chapter

The components of the Exadata Storage Servers that provide persistent storage services are the High Performance or High Capacity hard disks and the flash disks that are created on Sun Flash Accelerator F20 PCIe cards In this section, we will discuss the best practices for provisioning these storage devices and presenting them to Oracle ASM Once the storage is presented to Oracle ASM, you can create ASM diskgroups, and eventually create tablespaces in the Oracle database that utilizes the diskgroups to store database objects

LUNs, Cell Disks, and Grid Disks As shown in Figure 5-2, each hard disk gets presented to the Exadata Storage Server Software and the OS as a logical unit (LUN) A LUN is the representation of the hard disk to the OS The Exadata Storage Server Software will take the LUN and format it to create a cell disk There is a one-to-one relationship between a LUN and a cell disk When the cell disk is created, it reserves a small portion of the available storage on the LUN for a system area The system area is used to store information about the LUNs, cell disks, and grid disks (discussed next) created on top of the cell disks The system area on the first two drives is special since it stores the Oracle Linux operating system and the Linux file systems of the Exadata Storage Server Grid disks add another layer of logical abstraction on the physical storage and are created on top of cell disks Grid disks are the entities that get presented to Oracle ASM as ASM disks, and ASM diskgroups get created across the available ASM disks (ie, grid disks) You can create multiple grid disks per cell disk, and when a grid disk is created, it will carve out a chunk of space from the unused outer tracks of the physical disk The first grid disk created on the cell disk will allocate space from the outer tracks and move towards the inner tracks, reserving the number of tracks that correspond to the size of the grid disk This grid disk provides the fastest performance since the outer tracks of a hard disk provide the best read/write performance The next grid disk you will create starts from the tracks where the first grid disk ends, and this process repeats until you exhaust all the space on the cell disk or you are done creating the grid disks Creating multiple grid disks per cell disk allows you to create multiple pools of storage on the same Exadata Storage Server The multiple grid disks can be assigned to separate ASM diskgroups, which can be provisioned to different databases Even within the same database, you can store your
