Introduction

The Dell PowerVault ™ DL2000 – Powered by CommVault ® Simpana

® 8 Advanced Deduplication Edition delivers end-to-end block-based

deduplication to signicantly reduce MediaAgent disk storage

requirements. This technical note discusses how to congure

deduplication for primary storage policy copies on the PowerVault

DL2000 magnetic library to achieve high performance.

General Guidelines

For best performance when enabling deduplication for new primary

storage policy copies on the PowerVault DL2000:

• Specify magnetic library mount paths for the deduplication

stores (databases); never place deduplication stores on the

PowerVault DL2000 internal system drive (C:\).

• Set the block level deduplication factor to 64K for storage

policies that backup le data and to 128K for storage policies

that backup databases.

• Conrm that software compression and deduplication are

enabled for all subclients associated with these storage policies;

software compression and deduplication are enabled by default.

• Apply the Spill and Fill mount path allocation policy to the

PowerVault DL2000 magnetic library.

• Conrm that the Deduplication Performance Pack is installed on

the PowerVault DL2000.

Details on applying each of these conguring settings are provided

below.
