Introduction
The Dell PowerVault ™ DL2000 – Powered by CommVault ® Simpana
® 8 Advanced Deduplication Edition delivers end-to-end block-based
deduplication to signicantly reduce MediaAgent disk storage
requirements. This technical note discusses how to congure
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.
• Conrm 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.
• Conrm that the Deduplication Performance Pack is installed on
the PowerVault DL2000.
Details on applying each of these conguring settings are provided
below.
