Requirements

Prerequisites

Before installing the DPX Client on Linux, review the following prerequisites:

• The minimum hardware requirements are as follows:

Memory	2 GB minimum, 4 GB recommended for Enterprise applications
Processor	1 core minimum
Architecture	x64
Disk space	4 GB minimum free space on system drive for installation

• Ensure your client system is included in the DPX 4.10 Compatibility Matrix.

• The system resources and configurations of your client machine must meet the requirements as shown on the DPX product web page.

• Your client system must have the libnss3 plug-in. For example, you can install the libnss3 plug-in package in Red Hat Enterprise Linux 8 or supported variants of it by using the following command:

  $ sudo yum install libnss3.so

• Your client system must have the iSCSI packages for the Instant Access (IA) mapping which is one of the features for the Block Backup of DPX. The package name and installation steps may vary. For example, you can install the iSCSI packages in Red Hat Enterprise Linux 8 or supported variants of it by using the following command:

  $ sudo yum install iscsi-initiator-utils

• Allow all required ports for the Catalogic DPX Client:

• TCP: 3260, 6123, 6124, 9104, 9202, 10000, 10001, 10566, and 15660.

• UDP: 6123 and 6124.

Additional prerequisites

Some Linux distributions listed in the DPX 4.10 Compatibility Matrix support Block Data Protection in addition to file-level protection. To enable Block Data Protection, review the following additional prerequisites before installing the DPX Client on Linux:

• The storage volume to install the DPX Client for Linux must be part of an LVM group.

• The physical extent (PE) of the LVM volume group to install the DPX Client for Linux must have free PE of at least 10%.

Tip. Enable the Block Data Protection option to use the block-level snapshot technology that backs up only updated blocks. Block Data Protection may reduce backup time, transmission loads, CPU impacts, and storage requirements.

If you opt out of this option, DPX protects data by using the file-level backup instead.
