Features
The VxRail Series offers advanced features including automatic deployment, automatic scale out, fault
tolerance, and diagnostic logging.
Automatic deployment
The VxRail Manager fully automates the installation and configuration of all nodes in an appliance after
you input the basic IP address information.
Automatic scale-out
The VxRail Series provides automated scale-out functionality by detecting a new VxRail Appliance on the
network. When a new VxRail Appliance is powered on you can add it to your existing cluster or create a
new cluster, replicating the configuration, and expanding the datastore in a cluster.
Node failure tolerance
The VxRail Series supports from 0 to 3 node failures, as defined by the VSAN FTT policy. The following
table lists the minimum number of nodes in a cluster required to support a given number of node failures.

The VxRail Series implements the standard Virtual SAN policy of one failure by default:
•
An entire node can fail and the system will continue to function.
•
Disk failure cannot affect more than one node. One SSD can fail or as many as three HDDs on
the same node can fail.
•
One network port on any node can fail without affecting the node.
Network failover is through the virtual switch configuration in ESXi. This is automatically
configured by VxRail Manager during initial setup.
Logging and log bundles
The VxRail Series provides logging and log bundles through VxRail Manager.
