Installation Components

There are several fundamental data protection installation components for a DPX implementation:

  • Master server software. This is installed on the DPX virtual appliance that holds and manages the Catalog.

  • Client software. This is installed on every client node that requires a backup.

  • DPX Open Storage Server (OSS) software. This is for open storage users only. This component is installed on the Windows servers intended for Block backup to DPX open storage operations. Block backup to DPX open storage provides block-level incremental backup for Windows and Linux clients to any storage attached to a supported 64-bit Windows server.

The following are considerations for DPX open storage server installation:

  • For new installations, Windows 2012 R2 machine is the minimum version recommended.

  • A minimum of 4 GB of available memory is required for new installations; 8 GB or more is recommended.

  • A minimum of dual core CPU or two CPUs must be available.

  • If you upgraded from an older release such as BEX 3.4, your DPX open storage server continues to be supported.

  • Windows x64 is required. Cluster nodes are not supported.

  • DPX open storage servers must reside in only one DPX Enterprise and relate to only one master server.

  • A single Enterprise can contain multiple DPX open storage servers.

  • A DPX open storage server cannot be used for any purpose other than DPX. Additional applications or data on the server might reduce backup performance, which can reduce application performance and might increase the risk of storage data corruption.

  • It is not recommended to use the server for DISKDIRECTORY volumes or for reporting applications.

  • A highly reliable configuration such as RAID 5 with hot spares is recommended.

  • Free space is required on the server. Following are the default behaviors. If free space falls below 30%, a warning is issued. If free space falls below 20%, jobs may fail.

  • All storage volumes must be standard uncompressed NTFS. A DPX open storage server is not compatible with NTFS compression.

  • Microsoft iSCSI Initiator is required. However, the Microsoft iSCSI target service must not be running. See iSCSI Initiator and NFS Transport Protocol in the Reference Guide.

  • Do not use continuous, real-time, or online defragmentation utilities with the server. These utilities can interfere with backup, condense, and restore operations. The server is optimized to manage its files without additional defragmentation.
