vRealize Operations Manager 6.0 Sizing Guidelines

Products

• VMware Aria Suite

Issue/Introduction

Use the sizing guidelines for VMware vRealize Operations Manager 6.0 (formerly known as vCenter Operations Manager) to determine the configurations to be used during installation.

Environment

VMware vRealize Operations Manager 6.0.x

Resolution

By default, VMware offers Extra Small, Small, Medium, and Large configurations during installation. Size the environment according to the existing infrastructure to be monitored. After the vRealize Operations Manager (formerly known as vCenter Operations Manager) instance outgrows the existing size, expand the cluster to add nodes of the same size.

 

/Node Size	Extra Small	Small	Medium	Large	Standard Size Remote Controller	Large Size Remote Controller
vCPU	2	4	8	16	2	4
Memory (GB)	8	16	32	48	4	16
IOPS	See the attached Sizing Guidelines worksheet for details.
Disk Space
Single-Node Maximum Objects	100	2,000	6,000	10,000	1,500 (***)	10,000 (***)
Single-Node Maximum Collected Metrics (*)	50,000	1,000,000	3,000,000	5,000,000	NA	NA
Multi-Node Maximum Objects Per Node (**)	NA	2,000	4,000	8,000	NA	NA
Multi-Node Maximum Collected Metrics Per Node (**)	NA	1,000,000	2,000,000	4,000,000	NA	NA
Maximum Objects for 8-Node Maximum (**)	NA	16,000	32,000	64,000	NA	NA
Maximum Metrics for 8-Node Configuration (**)	NA	8,000,000	8,000,000	20,000,000	NA	NA

 

(*) Metric numbers reflect the total number of metrics that are collected from all adapter instances in vRealize Operations Manager. To get this number, you can go to the Cluster Management page, and view the adapter instances of each node at the bottom of the page. Get the number of metrics collected by each adapter instance. The sum of these metrics is what is estimated here.

Note: The number shown in the overall metrics on the Cluster Management page reflects the metrics that are collected and the metrics that vRealize Operations Manager creates.

(**) In large, 8-node configurations, note the reduction in maximum metrics to permit some head room.

(***) The object limit for the remote collector is based on the VMware vCenter adapter.

 

Notes:

• Maximum number of remote collectors certified: 30
• Maximum number of VMware vCenter adapter instances certified: 30
• Maximum number of VMware vCenter adapter instances that were tested on a single collector: 30
• Maximum number of certified concurrent users per node (regardless of the node size): 4
• The maximum number of analytics cluster nodes is 8, regardless of whether they are used for HA. If HA is enabled, the effective maximum is 4 nodes as the other 4 nodes are used for HA. Remote Collectors do not count against the maximum of 8 nodes.
• An object in this table represents a basic entity in vRealize Operation Manager that is characterized by properties and metrics that are collected from adapter data sources. Examples of objects include a virtual machine, a host, a datastore for a VMware vCenter adapter, a storage switch port for a storage devices adapter, an Exchange server, a Microsoft SQL Server, a Hyper-V server, or a Hyper-V virtual machine for a Hyperic adapter, and an AWS instance for a AWS adapter.
• The limitation of a collector per node - The object or metric limit of a collector is the same as the scaling limit of objects per node. The collector process on a node will support adapter instances where the total number of objects is not more than 2,000, 4,000, and 8,000 respectively, on a small, medium, and large multi-node vRealize Operations Manager cluster. For example, a 4-node system of small nodes will support a total of 8,000 objects. However, if an adapter instance needs to collect 5,000 objects, a collector that runs on a small node cannot support that, as a a small node can handle only 2,000 objects. In this situation, you can add a large remote collector or use a configuration that uses large nodes instead of small nodes.
• If the number of objects is close to the high-end limit, dependent on the monitored environment, increase the memory on the nodes. Contact Product Support for more details.
