HX managment subnet

[Networker_eg]

If I have 2 HX-Clusters sharing the same FI and uplink switches

Is it okey to share :

HX-mgmt vlan

HX-storage vlan

HX-replication vlan

between the 2 clusters or it is recommended to use different sub nets for each cluster 

My concern is HX management interface uses the MC address 224.0.0.18 to advertise so if the 2 clusters use the same subnet the SCVM of both clusters will join ,

[Clifford Aldan · Accepted solution]

It is ok to have both clusters using the same subnets
When each HX storage cluster is created, the storage controllers are assigned to a storage domain unique to each cluster

Thus, storage controllers from different storage domains will not join a cluster it's not assigned to

Keep the VLAN names different, but the VLAN ID can be the same

For example, a two 3-node cluster would look like this:

Hi Clifford. Does this mean that I can ignore the warning that pops up for the VLAN for the storage network?

VLAN
Validating 'storage-data' VLAN: 'xxx' specified for new cluster is already assigned

This is the only warning that pops up during validation. Can I skip validation.
