vSphere vMotion network IP addresses
The vSphere vMotion network requires contiguous IPv4 addresses, one for each HC380 node in the
cluster. In OneView InstantOn, you provide the first IP address as the starting address, and the program
automatically assigns all other IP addresses in sequence. Record the starting IP address on the
preinstallation worksheet ("
If you are installing CloudSystem, no additional IP addresses are needed.
Use the following examples for the required number of IP addresses:
•
For a 16-node cluster, you will need 16 contiguous IPv4 addresses.
•
For a two-node cluster, you will need 2 contiguous IPv4 addresses.
•
For a three-node cluster, you will need 3 contiguous IPv4 addresses.
Storage network IP addresses
The storage network requires five contiguous IPv4 addresses for the first node and three contiguous IPv4
addresses for every additional node. These IP addresses are used by the HC380 Management VM, iSCSI
initiators, and HPE StoreVirtual.
Use the following examples for the required number of IP addresses:
•
For a sixteen-node cluster, you will need 50 contiguous IPv4 addresses
•
For a two-node cluster, you will need 8 contiguous IPv4 addresses
•
For a three-node cluster, you will need 11 contiguous IPv4 addresses
In OneView InstantOn, you provide the first IP address as the starting address, and the program
automatically assigns all other IP addresses in sequence. Record the starting IP address on the
preinstallation worksheet ("
Planning for expansion
If you are planning to expand in the future, Hewlett Packard Enterprise recommends that you preallocate
the IP addresses that are needed for the future nodes. For each new expansion node, you need five IPv4
