Chapter 4. Installing and Configuring DX Storage

This chapter discusses how to set up and configure a basic DX Storage cluster.

Note

If you boot DX Storage from a Cluster Services Node (CSN), the required infrastructure

setup, installation and configuration updates are performed automatically as part of CSN

configuration so the tasks discussed in this chapter are not necessary or recommended.

This chapter discusses the following topics:

•

Section 4.1, "Licensing"

•

Section 4.2, "Configuring DX Storage"

•

Section 4.3, "Booting DX Storage Nodes"

•

Section 4.4, "Using Syslog"

You receive a DX Storage license for the contractually agreed amount of storage space for a given

cluster or a license is generated from the published aggregate of multiple capacity keys from the

CSN Console. The location of your license file is specified by the licenseFileURL parameter in

your node or cluster configuration file.

See one of the following sections for more information about licensing:

•

Section 4.1.1, "How Licensing Works"

•

Section 4.1.2, "About licenseFileURL"

•

Section 4.1.4, "About Other Licensing Checks"

•

Section 4.1.5, "Sample License"

DX Storage uses the following logic to determine your licensing:

1. The default license is 2TB per cluster.

2. DX Storage attempts to read the license file from the location specified by licenseFileURL.

3. If a valid license is found, DX Storage uses it.

If the file specified by licenseFileURL is not a valid license, the storage capacity is set at 0.

4. If DX Storage fails to read the license specified by licenseFileURL (for example, the file is on

a web server that is temporarily unavailable), DX Storage uses the last valid license.

Licensing troubleshooting suggestions:

• If the capacity of a node in your cluster is 0, make sure the license specified by

licenseFileURL is a valid DX Storage license. In particular, make sure no one has manually

edited the license because doing so invalidates the license key.
