There is a lot of great new enhancements and improvements added in 6.5 but for the sake of brevity I shall highlight two that I really liked.
Flexibility to increase RAM in between node sizes
So if you are familiar with vROps you will know that when you deploy it you have “T-Shirt” sizes to choose from, Small, Medium, Large and now Extra Large (6.5). However an additional extra in 6.5 is support to increase the memory allocation of your vROps nodes, you will not require additional CPU for the node until you hit the next node size bracket. If in doubt check the sizing guide spreadsheet VMware has provided so you can be sure on what you can and cannot do.
This flexibility plus the introduction of a new Extra Large Node size will give you more choice and flexibility with your existing or future vROps deployments.
Direct integration with Log Insight
There was already some integration with Log Insight via the launch in context menu, but now you can access Log Insight from the home page and also when you are troubleshoot individual objects. From a UX perspective this is fantastic and just saves time and further cements the relationship the two products have. You will still need to configure the Log Insight Management Pack and point it to the vLI instance you wish to integrate your vROps cluster with.
