When you install vRealize Operations Manager, you use a vRealize Operations Manager vApp deployment,
Linux installer, or Windows installer to create role-less nodes. After the nodes are created and have their
names and IP addresses, you use an administration interface to congure them according to their role.
You can create role-less nodes all at once or as needed. A common as-needed practice might be to add nodes
to scale out vRealize Operations Manager to monitor an environment as the environment grows larger.
The following node types make up the vRealize Operations Manager analytics cluster:
Master Node
The initial, required node in vRealize Operations Manager. All other nodes
are managed by the master node.
In a single-node installation, the master node manages itself, has adapters
installed on it, and performs all data collection and analysis.
Data Node
In larger deployments, additional data nodes have adapters installed and
perform collection and analysis.
Larger deployments usually include adapters only on the data nodes so that
master and replica node resources can be dedicated to cluster management.
Replica Node
To use vRealize Operations Manager high availability (HA), the cluster
requires that you convert a data node into a replica of the master node.
The following node type is a member of the vRealize Operations Manager cluster but not part of the
analytics cluster:
Remote Collector Node
Distributed deployments might require a remote collector node that can
navigate rewalls, interface with a remote data source, reduce bandwidth
across data centers, or reduce the load on the vRealize Operations Manager
analytics cluster. Remote collectors only gather objects for the inventory,
without storing data or performing analysis. In addition, remote collector
nodes may be installed on a dierent operating system than the rest of the
cluster.
VMware, Inc. 11
vRealize Operations Manager vApp Deployment and Configuration Guide
General vRealize Operations Manager Cluster Node Requirements
When you create the cluster nodes that make up vRealize Operations Manager, you have general
requirements that you must meet.
General Requirements
vRealize Operations Manager Version. All nodes must run the same vRealize Operations Manager
n
version.
For example, do not add a version 6.1 data node to a cluster of vRealize Operations Manager 6.2 nodes.
Analytics Cluster Deployment Type. In the analytics cluster, all nodes must be the same kind of
n
deployment: vApp, Linux, or Windows.
Do not mix vApp, Linux, and Windows nodes in the same analytics cluster.
Remote Collector Deployment Type. A remote collector node does not need to be the same deployment
n
type as the analytics cluster nodes.
When you add a remote collector of a dierent deployment type, the following combinations are
supported:
vApp analytics cluster and Windows remote collector
n
Linux analytics cluster and Windows remote collector
n
Analytics Cluster Node Sizing. In the analytics cluster, CPU, memory, and disk size must be identical
n
for all nodes.
Master, replica, and data nodes must be uniform in sizing.
Remote Collector Node Sizing. Remote collector nodes may be of dierent sizes from each other or
n
from the uniform analytics cluster node size.
Geographical Proximity. You may place analytics cluster nodes in dierent vSphere clusters, but the
n
nodes must reside in the same geographical location.
Dierent geographical locations are not supported.
Virtual Machine Maintenance. When any node is a virtual machine, you may only update the virtual
n
machine software by directly updating the vRealize Operations Manager software.
For example, going outside of vRealize Operations Manager to access vSphere to update VMware Tools
is not supported.
Redundancy and Isolation. If you expect to enable HA, place analytics cluster nodes on separate hosts.
n
See “About vRealize Operations Manager High Availability,” on page 27.
Requirements for Solutions
Be aware that solutions might have requirements beyond those for vRealize Operations Manager itself. For
example, vRealize Operations Manager for Horizon View has specic sizing guidelines for its remote
collectors.
See your solution documentation, and verify any additional requirements before installing solutions. Note
that the terms solution, management pack, adapter, and plug-in are used somewhat interchangeably.
12 VMware, Inc.
Chapter 1 Preparing for vRealize Operations Manager Installation
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 aect that communication. Examples include, but are not limited to, vMotions, storage vMotions,
HA events, and DRS events.
The master and replica nodes must be addressed by static IP address, or fully qualied domain name
n
(FQDN) with a static IP address.
Data and remote collector nodes may use dynamic host control protocol (DHCP).
You must be able to successfully reverse-DNS all nodes, including remote collectors, to their FQDN,
n
currently the node hostname.
Nodes deployed by OVF have their hostnames set to the retrieved FQDN by default.
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,
n
rewall, or a proxy that inhibits bidirectional communication by IP address or FQDN.
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
n
network (LAN).
Place analytics cluster nodes on same Layer 2 network and IP subnet.
n
A stretched Layer 2 or routed Layer 3 network is not supported.
Do not span the Layer 2 network across sites, which might create network partitions or network
n
performance issues.
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).
n
To collect data from a WAN, a remote or separate data center, or a dierent geographic location, use
remote collectors.
Remote collectors are supported through a routed network but not through NAT.
n
vRealize Operations Manager Cluster Node Best Practices
When you create the cluster nodes that make up vRealize Operations Manager, additional best practices
improve performance and reliability in vRealize Operations Manager.
Best Practices
Deploy vRealize Operations Manager analytics cluster nodes in the same vSphere cluster.
n
VMware, Inc. 13
vRealize Operations Manager vApp Deployment and Configuration Guide
If you deploy analytics cluster nodes in a highly consolidated vSphere cluster, you might need resource
n
reservations for optimal performance.
Determine whether the virtual to physical CPU ratio is aecting performance by reviewing CPU ready
time and co-stop.
Deploy analytics cluster nodes on the same type of storage tier.
n
To continue to meet analytics cluster node size and performance requirements, apply storage DRS anti-
n
anity rules so that nodes are on separate datastores.
To prevent unintentional migration of nodes, set storage DRS to manual.
n
To ensure balanced performance from analytics cluster nodes, use ESXi hosts with the same processor
n
frequencies. Mixed frequencies and physical core counts might aect analytics cluster performance.
To avoid a performance decrease, vRealize Operations Manager analytics cluster nodes need
n
guaranteed resources when running at scale. The vRealize Operations Manager Knowledge Base
includes sizing spreadsheets that calculate resources based on the number of objects and metrics that
you expect to monitor, use of HA, and so on. When sizing, it is beer to over-allocate than underallocate resources.
See Knowledge Base article 2093783.
Because nodes might change roles, avoid machine names such as Master, Data, Replica, and so on.
n
Examples of changed roles might include making a data node into a replica for HA, or having a replica
take over the master node role.
The NUMA placement is removed in the vRealize Operations Manager 6.3 and later. Procedures related
n
to NUMA seings from the OVA le follow:

2 Click OK.
3 Repeat these steps for all the VMs in the vRealize
Operations cluster.
4 Power on the cluster.
N To ensure the availability of adequate resources and continued product performance, monitor
vRealize Operations performance by checking its CPU usage, CPU ready and CPU contention time.
Using IPv6 with vRealize Operations Manager
vRealize Operations Manager supports Internet Protocol version 6 (IPv6), the network addressing
convention that will eventually replace IPv4. Use of IPv6 with vRealize Operations Manager requires that
certain limitations be observed.
Using IPv6
All vRealize Operations Manager cluster nodes, including remote collectors, must have IPv6 addresses.
n
Do not mix IPv6 and IPv4.
14 VMware, Inc.
Chapter 1 Preparing for vRealize Operations Manager Installation
All vRealize Operations Manager cluster nodes, including remote collectors, must be vApp or Linux
n
based. vRealize Operations Manager for Windows does not support IPv6.
Use global IPv6 addresses only. Link-local addresses are not supported.
n
If any nodes use DHCP, your DHCP server must be congured to support IPv6.
n
DHCP is only supported on data nodes and remote collectors. Master nodes and replica nodes still
n
require xed addresses, which is true for IPv4 as well.
Your DNS server must be congured to support IPv6.
n
When adding nodes to the cluster, remember to enter the IPv6 address of the master node.
n
When registering a VMware vCenter® instance within vRealize Operations Manager, place square
n
brackets around the IPv6 address of your VMware vCenter Server® system if vCenter is also using IPv6.
For example: [2015:0db8:85a3:0042:1000:8a2e:0360:7334]
Note that, even when vRealize Operations Manager is using IPv6, vCenter Server may still have an IPv4
address. In that case, vRealize Operations Manager does not need the square brackets.
You cannot register an Endpoint Operations Management agent in an environment that supports both
n
IPv4 and IPv6. In the event that you aempt to do so, the following error appears:
Connection failed. Server may be down (or wrong IP/port were used). Waiting for 10 seconds
before retrying.
Sizing the vRealize Operations Manager Cluster
The resources needed for vRealize Operations Manager depend on how large of an environment you expect
to monitor and analyze, how many metrics you plan to collect, and how long you need to store the data.
It is dicult to broadly predict the CPU, memory, and disk requirements that will meet the needs of a
particular environment. There are many variables, such as the number and type of objects collected, which
includes the number and type of adapters installed, the presence of HA, the duration of data retention, and
the quantity of specic data points of interest, such as symptoms, changes, and so on.
VMware expects vRealize Operations Manager sizing information to evolve, and maintains Knowledge Base
articles so that sizing calculations can be adjusted to adapt to usage data and changes in versions of
vRealize Operations Manager.
Knowledge Base article 2093783
The Knowledge Base articles include overall maximums, plus spreadsheet calculators in which you enter the
number of objects and metrics that you expect to monitor. To obtain the numbers, some users take the
following high-level approach, which uses vRealize Operations Manager itself.
1 Review this guide to understand how to deploy and congure a vRealize Operations Manager node.
2 Deploy a temporary vRealize Operations Manager node.
3 Congure one or more adapters, and allow the temporary node to collect overnight.
4 Access the Cluster Management page on the temporary node.
5 Using the Adapter Instances list in the lower portion of the display as a reference, enter object and
metric totals of the dierent adapter types into the appropriate sizing spreadsheet from Knowledge
Base article 2093783.
6 Deploy the vRealize Operations Manager cluster based on the spreadsheet sizing recommendation. You
can build the cluster by adding resources and data nodes to the temporary node or by starting over.
If you have a large number of adapters, you might need to reset and repeat the process on the temporary
node until you have all the totals you need. The temporary node will not have enough capacity to
simultaneously run every connection from a large enterprise.
VMware, Inc. 15
vRealize Operations Manager vApp Deployment and Configuration Guide
Another approach to sizing is through self monitoring. Deploy the cluster based on your best estimate, but
create an alert for when capacity falls below a threshold, one that allows enough time to add nodes or disk
to the cluster. You also have the option to create an email notication when thresholds are passed.
During internal testing, a single-node vApp deployment of vRealize Operations Manager that monitored
8,000 virtual machines ran out of disk storage within one week.
Add Data Disk Space to a vRealize Operations Manager vApp Node
You add to the data disk of vRealize Operations Manager vApp nodes when space for storing the collected
data runs low.
Prerequisites
Note the disk size of the analytics cluster nodes. When adding disk, you must maintain uniform size
n
across analytics cluster nodes.
Use the vRealize Operations Manager administration interface to take the node oine.
n
Verify that you are connected to a vCenter Server system with a vSphere client, and log in to the
n
vSphere client.
Procedure
1 Shut down the virtual machine for the node.
2 Edit the hardware seings of the virtual machine, and do one of the following:
Increase the size of Hard Disk 2.
n
You cannot increase the size when the virtual machine has snapshots.
Add another disk.
n
3 Power on the virtual machine for the node.
During the power-on process, the virtual machine expands the vRealize Operations Manager data partition.
Custom vRealize Operations Manager Certificates
By default, vRealize Operations Manager includes its own authentication certicates. The default certicates
cause the browser to display a warning when you connect to the vRealize Operations Manager user
interface.
Your site security policies might require that you use another certicate, or you might want to avoid the
warnings caused by the default certicates. In either case, vRealize Operations Manager supports the use of
your own custom certicate. You can upload your custom certicate during initial master node
conguration or later.
Custom vRealize Operations Manager Certificate Requirements
A certicate used with vRealize Operations Manager must conform to certain requirements. Using a custom
certicate is optional and does not aect vRealize Operations Manager features.
Requirements for Custom Certificates
Custom vRealize Operations Manager certicates must meet the following requirements.
The certicate le must include the terminal (leaf) server certicate, a private key, and all issuing
n
certicates if the certicate is signed by a chain of other certicates.
In the le, the leaf certicate must be rst in the order of certicates. After the leaf certicate, the order
n
does not maer.
16 VMware, Inc.
Chapter 1 Preparing for vRealize Operations Manager Installation
In the le, all certicates and the private key must be in PEM format. vRealize Operations Manager
n
does not support certicates in PFX, PKCS12, PKCS7, or other formats.
In the le, all certicates and the private key must be PEM-encoded. vRealize Operations Manager does
n
not support DER-encoded certicates or private keys.
PEM-encoding is base-64 ASCII and contains legible BEGIN and END markers, while DER is a binary
format. Also, le extension might not match encoding. For example, a generic .cer extension might be
used with PEM or DER. To verify encoding format, examine a certicate le using a text editor.
The le extension must be .pem.
n
The private key must be generated by the RSA or DSA algorithm.
n
The private key must not be encrypted by a pass phrase if you use the master node conguration
n
wizard or the administration interface to upload the certicate.
The REST API in this vRealize Operations Manager release supports private keys that are encrypted by
n
a pass phrase. Contact VMware Technical Support for details.
The vRealize Operations Manager Web server on all nodes will have the same certicate le, so it must
n
be valid for all nodes. One way to make the certicate valid for multiple addresses is with multiple
Subject Alternative Name (SAN) entries.
SHA1 certicates creates browser compatibility issues. Therefore, ensure that all certicates that are
n
created and being uploaded to vRealize Operations Manager are signed using SHA2 or newer.
Sample Contents of Custom vRealize Operations Manager Certificates
For troubleshooting purposes, you can open a custom certicate le in a text editor and inspect its contents.
PEM Format Certificate Files
A typical PEM format certicate le resembles the following sample.

vRealize Operations Manager vApp Deployment and Configuration Guide
If this node is to be the master node, reserve a static IP address for the virtual machine, and know the
n
associated domain name server, default gateway, and network mask values.
Plan to keep the IP address because it is dicult to change the address after installation.
If this node is to be a data node that will become the HA replica node, reserve a static IP address for the
n
virtual machine, and know the associated domain name server, default gateway, and network mask
values.
Plan to keep the IP address because it is dicult to change the address after installation.
In addition, familiarize yourself with HA node placement as described in “About vRealize Operations

Preplan your domain and machine naming so that the deployed virtual machine name will begin and
n
end with alphabet (a–z) or digit (0–9) characters, and will only contain alphabet, digit, or hyphen (-)
characters. The underscore character (_) must not appear in the host name or anywhere in the fully
qualied domain name (FQDN).
Plan to keep the name because it is dicult to change the name after installation.
For more information, review the host name specications from the Internet Engineering Task Force.
See www.ietf.org.
Preplan node placement and networking to meet the requirements described in “General vRealize
n
Operations Manager Cluster Node Requirements,” on page 12 and “vRealize Operations Manager
Cluster Node Networking Requirements,” on page 13.

About the vRealize Operations Manager Master Node
The master node is the required, initial node in your vRealize Operations Manager cluster.
In single-node clusters, administration and data are on the same master node. A multiple-node cluster
includes one master node and one or more data nodes. In addition, there might be remote collector nodes,
and there might be one replica node used for high availability.
The master node performs administration for the cluster and must be online before you congure any new
nodes. In addition, the master node must be online before other nodes are brought online. If the master node
and replica node go oine together, bring them back online separately. Bring the master node completely
online rst, and then bring the replica node online. For example, if the entire cluster were oine for any
reason, you would bring the master node online rst.

Scaling vRealize Operations Manager
Out by Adding a Data Node 3
You can deploy and congure additional nodes so that vRealize Operations Manager can support larger
environments.
This chapter includes the following topics:
“About vRealize Operations Manager Data Nodes,” on page 25
n
“Run the Setup Wizard to Add a Data Node,” on page 25
n
About vRealize Operations Manager Data Nodes
Data nodes are the additional cluster nodes that allow you to scale out vRealize Operations Manager to
monitor larger environments.
A data node always shares the load of performing vRealize Operations Manager analysis and might also
have a solution adapter installed to perform collection and data storage from the environment. You must
have a master node before you add data nodes.
You can dynamically scale out vRealize Operations Manager by adding data nodes without stopping the
vRealize Operations Manager cluster. When you scale out the cluster by 25% or more, you should restart the
cluster to allow vRealize Operations Manager to update its storage size, and you might notice a decrease in
performance until you restart. A maintenance interval provides a good opportunity to restart the
vRealize Operations Manager cluster.
In addition, the product administration options include an option to re-balance the cluster, which can be
done without restarting. Rebalancing adjusts the vRealize Operations Manager workload across the cluster
nodes.
N Do not shut down online cluster nodes externally or by using any means other than the
vRealize Operations Manager interface. Shut down a node externally only after taking it oine in the
vRealize Operations Manager interface.

Adding High Availability to
vRealize Operations Manager 4
You can dedicate one vRealize Operations Manager cluster node to serve as a replica node for the
vRealize Operations Manager master node.
This chapter includes the following topics:
“About vRealize Operations Manager High Availability,” on page 27
n
“Run the Setup Wizard to Add a Master Replica Node,” on page 28
n
About vRealize Operations Manager High Availability
vRealize Operations Manager supports high availability (HA). HA creates a replica for the
vRealize Operations Manager master node and protects the analytics cluster against the loss of a node.
With HA, data stored on the master node is always 100% backed up on the replica node. To enable HA, you
must have at least one data node deployed, in addition to the master node.
HA is not a disaster recovery mechanism. HA protects the analytics cluster against the loss of only one
n
node, and because only one loss is supported, you cannot stretch nodes across vSphere clusters in an
aempt to isolate nodes or build failure zones.
When HA is enabled, the replica can take over all functions that the master provides, were the master to
n
fail for any reason. If the master fails, failover to the replica is automatic and requires only two to three
minutes of vRealize Operations Manager downtime to resume operations and restart data collection.
When a master node problem causes failover, the replica node becomes the master node, and the cluster
runs in degraded mode. To get out of degraded mode, take one of the following steps.
Return to HA mode by correcting the problem with the master node, which allows
n
vRealize Operations Manager to congure the node as the new replica node.
Return to HA mode by converting a data node into a new replica node and then removing the old,
n
failed master node. Removed master nodes cannot be repaired and re-added to
vRealize Operations Manager.
Change to non-HA operation by disabling HA and then removing the old, failed master node.
n
Removed master nodes cannot be repaired and re-added to vRealize Operations Manager.
In the administration interface, after an HA replica node takes over and becomes the new master node,
n
you cannot remove the previous, oine master node from the cluster. In addition, the previous node
continues to be listed as a master node. To refresh the display and enable removal of the node, refresh
the browser.
VMware, Inc.
27
vRealize Operations Manager vApp Deployment and Configuration Guide
When HA is enabled, the cluster can survive the loss of one data node without losing any data.
n
However, HA protects against the loss of only one node at a time, of any kind, so simultaneously losing
data and master/replica nodes, or two or more data nodes, is not supported. Instead,
vRealize Operations Manager HA provides additional application level data protection to ensure
application level availability.
When HA is enabled, it lowers vRealize Operations Manager capacity and processing by half, because
n
HA creates a redundant copy of data throughout the cluster, as well as the replica backup of the master
node. Consider your potential use of HA when planning the number and size of your
vRealize Operations Manager cluster nodes. See “Sizing the vRealize Operations Manager Cluster,” on
page 15.
When HA is enabled, deploy analytics cluster nodes on separate hosts for redundancy and isolation.
n
One option is to use anti-anity rules that keep nodes on specic hosts in the vSphere cluster.
If you cannot keep the nodes separate, you should not enable HA. A host fault would cause the loss of
more than one node, which is not supported, and all of vRealize Operations Manager would become
unavailable.
The opposite is also true. Without HA, you could keep nodes on the same host, and it would not make a
dierence. Without HA, the loss of even one node would make all of vRealize Operations Manager
unavailable.
When you power o the data node and change the network seings of the VM, this aects the IP
n
address of the data node. After this point, the HA cluster is no longer accessible and all the nodes have
a status of "Waiting for analytics". Verify that you have used a static IP address.

bctid=ref:video_vrops_create_replica_node_ha)
Run the Setup Wizard to Add a Master Replica Node
You can convert a vRealize Operations Manager data node to a replica of the master node, which adds high
availability (HA) for vRealize Operations Manager.
N If the cluster is running, enabling HA restarts the cluster.
If you convert a data node that is already in use for data collection and analysis, adapters and data
connections that were provided through that data node fail over to other data nodes.
You may add HA to the vRealize Operations Manager cluster at installation time or after
vRealize Operations Manager is up and running. Adding HA at installation is less intrusive because the
cluster has not yet started.
Prerequisites
