• The CPU generations in all compute nodes must match for proper VMware vMotion functionality. After you
select a compute node from the inventory, you cannot select compute nodes with different CPU
generations.
• You cannot intermix compute nodes with GPU-enabled compute nodes in the same compute cluster. If you
select a GPU-enabled compute node, CPU-only compute nodes become unselectable, and vice versa.
• The software version running on the compute node must match the major and minor version of the NetApp
Deployment Engine hosting the deployment. If this is not the case, you need to reimage the compute node
using the RTFI process. See the NetApp Knowledgebase articles regarding RTFI for instructions.
• The compute node must have the cabling configuration you selected on the Network Topology page to be
selectable in the Compute Nodes list.
• The network cabling configurations for compute nodes of the same model must match within a single
compute cluster.

Select inventory
On the Inventory page, the NetApp Deployment Engine automatically detects available
compute and storage nodes, enabling you to select and add all NetApp HCI resources to
the deployment. If a node does not meet the requirements for deployment, it is not
selectable and problems are indicated as errors. You can position your cursor over the
error in the node’s row to see an explanation. When choosing node inventory on the
Inventory page, the storage node that is hosting the NetApp Deployment Engine is
automatically selected, and you cannot deselect it.
What you’ll need
Jumbo frames must be enabled for proper inventory detection. If no nodes or only a subset of nodes appear in
the inventory, verify that the switch ports used for NetApp HCI nodes (all SFP+/SFP28 interfaces) are
configured with jumbo frames.
Steps
1. On the Inventory page, view the list of available nodes.
If the system cannot detect any inventory, it displays an error. Correct the error before continuing.
If your system uses DHCP for IP address assignment, the storage and compute resources might not
appear in the inventory immediately.
2. Optional: If a resource does not appear in the inventory immediately, or if you address an error and need to
refresh the inventory, click Refresh Inventory. You might need to refresh the inventory multiple times.
3. Optional: To filter the inventory on node attributes, such as node type:
a. Click Filter in the header of the Compute Nodes or Storage Nodes lists.
b. Choose criteria from the drop-down lists.
c. Below the drop-down lists, enter information to satisfy the criteria.
d. Click Add Filter.
