Business’s that run their most critical applications on VMware and store their data on IBM Spectrum Virtualize Storage have a challenge; to meet the performance requirements of a variety of production applications and users, while meeting SLAs When problems arise, the IT managers expect these IT teams to work together to resolve the problems very quickly.

In many organizations there's usually more than one IT team involved in resolving performance issues which can create many obstacles when working to meet the SLAs.    In this whitepaper, we take a look at the day to day challenges in today's IT environment and how a true end-to-end visibility  of VMware and IBM Spectrum Virtualize environment helps IT teams overcome these obstacles.

The Challenge

When performance issues arise, the different IT teams  have to come together to resolve them in a timely manner. One of the obstacles that arise, is that each team is in it's own silo and each have a different set of technical skills and use their own tools. In addition, each team is also using more than one tool set to get the job done. This can cause discrepancies in the results when looking for answers; which can create a delay in solving the performance issues and can also create a lot of finger pointing.

An efficient way of monitoring and resolving performing issues across both environments requires an insight that includes a deep integration between both environments where the performance is correlated between the two layers. The tools available have been designed independent of each other.

When this insight and flexibility into both layers is not available to the administrator, finding the slow drainer in the VMware environment can be difficult and can take away time from other critical duties.

Second, the lack of pre-defined dashboards that help with the monitoring and troubleshooting process can make it even harder to find the slow drainer.

True end-to-end monitoring and performance analysis across VMware and Storage

BVQ has the solution to the IT challenges because it offers:

True end-to-end integration of VMware and IBM Storage layers with a granular and full visibility of correlated performance information across both layers with ready to go dashboards.

Therefore, BVQ bridges silos while offering the highest quality of performance analytics with a consistent monitoring and alerting solution.                

Ready to go Dashboards to help Monitor and find the slow drainer - Use case where users are experiencing high response times on production applications

The ready to go dashboards accessible with just one click, provide the views of both environments in a unified interface.   This enables the administrator to seamlessly troubleshoot both environments and get to the root of the problem.  VM and storage administrators perform their day to day activities more efficiently.

Customer Use Case: we walk you through how one of our customers uses the pe-defined dashboards to find the slow drainer in the VMware environment

You can choose to monitor the environment from the VMware side and use two of the specialized dashboards. needed to check the resource contention and the storage performance in a single view monitoring and performance problem resolution of the VMware and Spectrum Virtualize Storage

The dashboards offer the following functionalities to help you effectively pinpoint the area where the bottleneck is happening:

  • See the activity levels of all Hosts you are interested in monitoring in a single view

  • Easily identify a saturation in the memory, CPU or IO on the ESXi host and pinpoint quickly particular VM causing the saturation
  • Ability to compare several objects to get a clear understanding if it’s just one VM that’s impacted or if it’s a chronic issue where more than one VM is impacted, by seeing all VMs spanning across several ESXi Hosts.
  • See the IO load on the VM LUN -data rate and latency to check for spikes. From identified spikes that surpass threshold levels determine the issue is coming from the storage side and identify which VM is causing that peak load

Use case scenario: from the dashboard 1
BVQ provides a performance correlation between the two layers

BVQ wil help you Then remediation steps can be implemented to either move VMs to different hosts or add more resources to the host.

-Which VM is driving that particular IO load? Yes because it can see al VMs running on this backend volume of the ESX host. And pinpoint the particular VM driving the high IO load. You have aidentified the bottleneck,now this vm can be moved to a different host or dig further

-Can drill down to the not only to the Datastore level , but it can also go to the backend  to the SCSI lun.  Let me show you how, show favorite


Here you can see which ESX is causing a high load on the backend disk.


Also can identify which Vm is driving that particular high IO load (here)and go to the SCSi LUN vm is using

-and see the performance Io and latency of the virtual disk

-and see the volume on the storage that it is using. And immediately see if there is a latency issue with the volume so that further analysis can be donwn ow on the storage side


Steps to solve the problem

  1. It has to be found out why the storage responds to the higher load with this high latency. This is a standard storage analysis supported by BVQ.
  2. If the storage is overloaded, a decision must be made whether to move this virtual machine to another storage.
  3. If a SAN problem is detected, you can do a SAN analysis with the BVQ SAN extension.
