Setting up the Dell DR Series System with IBM Tivoli Storage Manager

B

Best practices/considerations

B.1

Deduplication

The DR Series system has inline deduplication built-in and does not require any additional deduplication to

be done ahead of data being written to the DR Series system. The system will remove any redundancies in

the data before the data is stored on disk.

Enabling deduplication before the data stream is sent to the DR Series system will cause the data to be

obfuscated, not allowing the system to achieve optimal dedupe savings. It is highly recommended that

deduplication is not done before the data stream is sent to the DR Series system.

B.2

Compression

The DR Series system has compression built-in and does not require any additional compression to be

done ahead of data being written to the DR Series system. The system will remove any redundancies in the

data before being stored on disk.

Enabling compression before the data stream is sent to the DR Series system will cause the data to be

obfuscated, not allowing the system to achieve optimal savings. It is highly recommended that

compression is not done before the data stream is sent to the DR Series system.

B.3

Encryption

The DR Series system supports encryption-at-rest; hence there is no need to enable encryption for the

data management application.

Enabling encryption before the data stream is sent to the DR Series system will cause the data to be

obfuscated, not allowing the DR series devices to achieve optimal savings. It is highly recommended that

encryption is not done before the data stream is sent to the DR Series system. It supports encryption on

the wire for transferring data to remote sites using replication.

B.4

Space reclamation

For optimal performance, DR Series system and TSM backup and space reclamations jobs should be

scheduled to happen at different times.
