Drive expansion procedure
NOTE
:
Both SSD and HDD disk drives are fragile and cannot tolerate rough handling. There is
the potential of damaging a drive when electrostatic charges that accumulate on your body
discharge through the circuits. Do not attempt any replacement procedures unless you
understand and follow proper ESD handling procedures. If in doubt, have Dell EMC field
personnel perform the procedure.
VxRail appliance can be scaled-up by adding disk to a node if there are available drive slots.
Take note of the restrictions listed below. Consult your Dell EMC systems engineer for specific
details.
Only drives purchased from Dell EMC specifically for VxRail can be added to a VxRail
appliance. Other drive types are not supported and cannot be added to a VxRail Cluster.
Drives placement in the VxRail appliance is important. SSD drives to be used for cache
must be installed in specific slots. This drive slot locations vary for different VxRail models.
Disk group configuration rules must be followed. For example, while there may be available
slots within a node, it may not be possible to add additional drives to the disk group.
A disk group includes one cache drive and a minimum of one capacity drives. The maximum
number of capacity drives per disk group vary for different VxRail models.
The specific SSD drive types used for caching and capacity are different.
While nodes within a VxRail cluster may have different drive configurations, a consistent
drive configuration across all nodes in a VxRail cluster is recommended.
Procedure
The following procedure lists the high-level steps for adding drives to an existing VxRail node.
For more detailed procedures for specific hardware configurations, see the procedures

.
1. Within VxRail Manager, open the Health, Physical view for the node where you will be
adding the drive and select the back view.
2. In the Node Information box, click
