vRealize Operations Manager (vRops) as the name suggests is a monitoring tool from VMware, started as a virtualization specific but now it expands to all the dimensions of Datacenter and public Cloud.
Personally its one of my favorite tools from VMware.
i know you guys will talk about cost but here i am only referring to the technical part of it, where a newer version comes roughly every 6 months, every time they just surprise me with the feature releases.
In this blog, i will be talking to those admins who want to deploy vRops in their environment but is struggling with sizing.
Excel based sizing is old school now, use this.
vRealize Sizing Tool: it covers all current and old versions from 6.5 onward till 7.5.
To calculate the sizing you need to look deeper into your need like:
1) How many vCenters you want to connect to?
2) No of VM’s, ESXi hosts, DataStores!!!
Basically trying to calculate the no of objects.
If in case you want to monitor more than your vCenter, that’s also possible through Plugins for UCS FI, Brocade Switch’s, DELL H/W, EMC Storage (these are just some examples visit marketplace to check the available Plugins)
Enough said, Lets get started:
Go to the link of vRealize Sizing and select the version which you want to deploy.
Their are 2 types of Sizing Guide :
i) Basic: where only vCenter related objects will define the size of vRops.
Note: As an example i am selecting vRops 7.5 and will show basic sizing.
Additional Parameter: They are quite self explanatory like growth in infra, retention period and HA requirement for vROps VM’s.
After adding all the information into basic sizing tool with additional parameters -> click on -> View Recommendation.
Output 1: Minimum is 2 Nodes Cluster (HA enabled) with 16 vCPU and 64 GB RAM using 1404 GB Storage for the time interval selected.
ii) Advanced: where not only the vCenter related objects but the additional plugins for Network,Storage, Services etc will be considered.
Note: As an example i am selecting vRops 7.5 and will show advanced sizing.
So from the above screen shot, its visible some of the object list which can be used in sizing vROps.
For example, i am using vCenter, NSX and vCloud director objects here.
Click View Recommendation.
Output 2: Minimum is 2 Nodes Cluster (HA enabled) with 16 vCPU and 64 GB RAM using 1424 GB Storage for the time interval selected.
Conclusion: Use this to make a educated sizing for the environment, so that don’t need to perform the vRops Cluster maintenance after going Live.
