• Data retention and validation. Data retention ensures that files cannot be modified or deleted

for a specific retention period. Data validation scans can be used to ensure that files remain

unchanged. See “Managing data retention” (page 143).

• Antivirus support. This feature is used with supported Antivirus software, allowing you to scan

files on an IBRIX file system. See “Configuring Antivirus support” (page 192).

• IBRIX software snapshots. This feature allows you to capture a point-in-time copy of a file

system or directory for online backup purposes and to simplify recovery of files from accidental

deletion. Users can access the file system or directory as it appeared at the instant of the

snapshot. See “Creating IBRIX software snapshots” (page 204).

• Block Snapshots. This feature uses the array capabilities to capture a point-in-time copy of a

file system for online backup purposes and to simplify recovery of files from accidental deletion.

The snapshot replicates all file system entities at the time of capture and is managed exactly

like any other file system. See “Creating block snapshots” (page 213).

• Data tiering. This feature allows you to set a preferred tier where newly created files will be

stored. You can then create a tiering policy to move files from initial storage, based on file

attributes such as such as modification time, access time, file size, or file type. See “Using

data tiering” (page 225).

• File allocation. This feature allocates new files and directories to segments according to the

allocation policy and segment preferences that are in effect for a client. An allocation policy

is an algorithm that determines the segments that are selected when clients write to a file

system. See “Using file allocation” (page 240).

Accessing file systems

Clients can use the following standard NAS protocols to access file system data:

• NFS. See “Using NFS” (page 51) or more information.

• SMB. See “Using SMB” (page 73) for more information.

• FTP. See “Using FTP” (page 98) for more information.

• HTTP. See “Using HTTP” (page 108) for more information.

You can also use IBRIX 9000 clients to access file systems. Typically, these clients are installed

during the initial system setup. See the HP IBRIX 9000 Storage Installation Guide for more

information.
