Application awareness for VMware is a new feature of Unisphere for PowerMax, which allows users to troubleshoot storage related problems to ESXi servers.

 

Using a read only vCenter user account, a vCenter or an individual ESXi server can be added to Unisphere.

 

The discovered items are then associated with local storage devices to Unisphere and mapped to storage related objects making it easier to investigate possible storage related problems.

 

The following are some of the actions a user can view on this new feature:

 

  • Masking Views related to ESXi server
  • Performance KPIs related to ESXi Server
  • Details of ESXi Server
  • Virtual Machines on ESXi Server
  • Storage Groups related to ESXi Server
  • Local Storage Capacity of ESXi Server
  • Details of Virtual Disk under a VM
  • Allows you to find the ESXi Server a VM resides on and related storage objects.

 

It is easy to identify potential storage related issues associated with your ESXi server by examining the main vCentre/ESXi server list view.

 

If any Storage Group is out of compliance an indication will display too highlight, also if there is a problem with Front End Ports utilization then this will able be indicated. Clear relationships between the storage objects and vCenter/Esxi server(s) make diagnosis of a potential problem swift.

 

The ability to locate an ESXi when given a particular VM name accelerates troubleshooting efforts and can rule in/out the problem having anything to do with the local storage array.

 

Discovery of VMware related objects can be scheduled by using the Job feature of Unisphere for PowerMax.

Getting Started with VMware Unisphere

 

Login to Unisphere for PowerMax

 

Select HOME > VMWARE > vCenters and ESXi

The user can then register a whole vCenter or add individual ESXi servers. Registering is easy!

 

All that is required is the vCenter/ESXi server name or IP address and a username and password.

 

The user then has the option to run the discovery now or Add to Job List and run at the required time.

Once done you get can view the esxi servers listed for the vCenter - note this only shows Esxi servers local to PowerMAX!

 

Storage group compliance and Front End colour coded status indicators draws your eye quickly to any potential issue. More information is readily available such as the VMware version and build number, CPU cores, Memory by double clicking one to the esxi server.

Investigate a potential SG Compliance Problem

 

In this use case the user is presented with a yellow warning triangle in the Storage Group compliance column in the main list view.

 

This means this Storage Group is outside of the maximum response time for it's defined service level and might indicate a potential problem. Workload Planner calculates its weighted response time for the past 4 hours and for the past 2 weeks, and then compares the two values to the maximum response time associated with its given service level.

 

If one of them is in compliance and the other is out of compliance, then the compliance state is MARGINAL. If both are out of compliance, then the compliance state is CRITICAL.

To investigate further you can View All Details of an ESXi and navigate to the Performance tab.

Here you can see more KPIs and some other related performance objects.

 

Once the potential troublesome SG is determined the user can also now navigate to the Performance section of Unisphere and investigate further.

A tip/trick I found useful when trying to locate an Esxi server or VM is to use the Unisphere for PowerMax search icon.

Great to hear your thoughts on this fantastic VMware application awareness in Unisphere!
