This chapter describes how to set up High Availability (HA) for V6x00 hardware and virtual appliances. Refer to the
High Availability chapter in the DSM Administrators Guide for details about managing an HA deployment.
HA Overview
To configure High Availability (HA) for DSMs, you need to be a System/All administrator and have DSM CLI
privileges. A DSM HA configuration consists of two or more DSM HA nodes.
As of DSM v6.2.0, HA is now configured as Active-Active. This means that there is no longer a primary or a failover
node. All nodes are peers. When one node fails, the other nodes continue operating normally. When the failed node is
working properly again, it synchronizes with the other HA nodes. that if you are migrating from 6.1.x or an earlier
version, then you can't upgrade or migrate. You have to create a new cluster.
Note
If you are migrating from an HA cluster that is DSM v6.1.x or an earlier version, then you cannot upgrade or
migrate your cluster to 6.2.x or 6.3.x. You must create a new cluster. See "Migrating from DSM
v6.1.0.9229 to DSM 6.4.2" on page113 for more information.
Supported HA Deployments
You must have at least two DSM HA nodes installed on the same network to create an HA cluster. The maximum
number of nodes allowed in an HA cluster is eight.
To ensure reliable operation, the appliances in an HA cluster must run the same version of the DSM software and have
the same hardware configurations.
V6100
A DSM high availability (HA) cluster for a V6100 must consist of only v6100 appliances. You cannot mix it with other
DSM appliances (V6000 or virtual DSM).
V6000 and Virtual Appliances
An HA cluster may consist of both V6000 and virtual DSMs.
If you plan to create an HA cluster for a network HSM-enabled DSM, then all nodes in the cluster must be network
HSM-enabled appliances so that they can all connect to the network HSM.
Configuring HA for V6x00 and Virtual Appliances
This section describes how to configure an HA cluster for a V6100 or virtual appliance in an HA cluster.
