vRealize Operations Manager Cluster Node Networking Requirements
When you create the cluster nodes that make up vRealize Operations Manager, the associated setup within
your network environment is critical to inter-node communication and proper operation.
Networking Requirements
I vRealize Operations Manager analytics cluster nodes need frequent communication with one
another. In general, your underlying vSphere architecture might create conditions where some vSphere
actions aect that communication. Examples include, but are not limited to, vMotions, storage vMotions,
HA events, and DRS events.
n
The master and replica nodes must be addressed by static IP address, or fully qualied domain name
(FQDN) with a static IP address.
Data and remote collector nodes may use dynamic host control protocol (DHCP).
n
You must be able to successfully reverse-DNS all nodes, including remote collectors, to their FQDN,
currently the node hostname.
Nodes deployed by OVF have their hostnames set to the retrieved FQDN by default.
n
All nodes, including remote collectors, must be bidirectionally routable by IP address or FQDN.
n
Analytics cluster nodes must not be separated by network address translation (NAT), load balancer,
rewall, or a proxy that inhibits bidirectional communication by IP address or FQDN.
n
Analytics cluster nodes must not have the same hostname.
n
Place analytics cluster nodes within the same data center and connect them to the same local area
network (LAN).
n
Place analytics cluster nodes on same Layer 2 network and IP subnet.
A stretched Layer 2 or routed Layer 3 network is not supported.
n
Do not span the Layer 2 network across sites, which might create network partitions or network
performance issues.
n
One-way latency between analytics cluster nodes must be 5 ms or lower.
n
Network bandwidth between analytics cluster nodes must be 1 gbps or higher.
n
Do not distribute analytics cluster nodes over a wide area network (WAN).
To collect data from a WAN, a remote or separate data center, or a dierent geographic location, use
remote collectors.
n
Remote collectors are supported through a routed network but not through NAT.
