Technical Marketing Engineer Hybrid Cloud Infrastructures at NetApp
Centralized policies have simplified hybrid operations and now support automated workflows
The challenge could be if there are any bugs. Most of the time, you may feel that the TCAM resources are getting full on the Nexus just because of some bug or the configuration is not supported. Or sometimes, if there are any vulnerabilities happening on the current running firmware, those are challenges we have. And if you talk about from the compute side, there were initial bugs such as a CPU throttle issue. Because of that, the chassis was not running in an optimum way. You may see performance issues during that time. For that, Cisco released a patch, and it got fixed. I think Cisco Intersight should allow more automation capabilities. It should be more open, and it should provide more automation capabilities. I think there is also a scope of making it a little bit simpler because a lot of policy and config sometimes becomes confusing for the user because it has a lot of config. Maybe they can do a little bit of simplification with Cisco Intersight.

The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.
