Shining a light on Hitachi Storage Adapter for VMware vC Ops (hmm vROPS)

Blog Post created by Paul Morrissey Employee on Nov 7, 2014

VMware vCenter Operations Management Suite (recently rebranded as VMware vRealize Operations) has become an integrated part of today’s data center management stack due its ability to monitor virtual infrastructure hypervisor and associated 3rd party infrastructure including network, compute and storage from single-pane-of-management console. It provides performance, capacity, alerting and configuration management for VMware vSphere environments. Among several available tools to manage vSphere infrastructure vC Ops (or vROPS) stands out because of its ability to abstract status of underlying virtual and physical elements into intuitively consumable dashboards for virtual infrastructure admin to optimally manage IT environment and fast track problem resolution areas.

Hitachi Data Systems has taken significant leap to complement vC Ops capabilities by recently releasing a new Hitachi Storage Adapter for VMware vCenter Operations Management. This now enables a VI admin to have unified comprehensive view inclusive of Hitachi Storage platforms and enable resource optimization with this deeper insight. I briefly wrote about this adapter in my last blog but thought I would share some additional details on it. We have heard positive reviews from customers and partners alike for the value it provides to VI admin in the form of performance matrix, end-to-end resource mapping and resource utilization. Detailed resource mapping allows faster issue resolution, proactive monitoring and root-cause analysis enabling IT to respond to business needs.


The adapter also comes pre-loaded out-of-the-box with intuitive dashboards on storage performance, capacity and top consumers for Hitachi Storage arrays, enabling  a simple, agile and efficient solution to your virtual infrastructure needs. Let’s have a peek at the dashboards.

Dashboard: Hitachi VM Performance

The Hitachi VM Performance Dashboard heat map views provide visual representation of possible performance problems based upon VMDK latency or IOPS levels at the VM guest operating system layer. The dashboard are layed out to show a heat map on the left and a resource tree on the right.


This dashboard provides a heat map with 2 views: latency and IOPS. The views are grouped by vSphere cluster and vSphere resource group.[This allows for identification of misbehaving virtual machines within a common group of peer virtual machines]

  • Latency view is sized based on compute shares assigned to VM, and is colored based on overall VMDK latency at the VM.
  • IOPS view is sized based on number of IOPS VM is generating, colored based on overall VMDK latency at the VM.

The intent is by sizing the heat map objects for the VMDK IOPS view by commands per second for example, you can identify virtual machines generating the most IOPS by size and have a visual color reference on the comparative latency been seen by those VMs

You can also customize the threshold of each object to suit your specific needs for when an object goes from orange to red for example. We provide default thresholds such as yellow, orange, red thresholds when IO port activity crosses 800,1000, 1200 MB/sec

When you click on a VM name on the left pane,  the administrator can also see all the storage resources associated with a specific VM all the way down to the cache level. This enables admin to quickly discern if any storage resources impacting VM performance. With this information you should be able to quickly identify storage bottlenecks, make proactive changes if necessary to ensure continuous operating storage environment for virtual machine performance

Dashboard: Hitachi VM Capacity

The Hitachi VM Capacity Dashboard heat map view provides visual representation of possible datastore capacity problems based upon the available capacity of underlying (dynamic provisioning) volume on the storage array. The VM capacity dashboard for the Hitachi storage adapter has a heat map of your Dynamic Provisioning Volume capacity. Capacity view is sized on total datastore (DPVol) capacity (more total capacity = larger size) and colored based on Datastore (DPVol) capacity usage % i.e. The size represents the capacity, while the color shows the usage percentage of the Datastore. Again, the default thresholds and color coding can be changed for your environment needs. (e.g yellow threshold color coding fires off at 75%)

Also, by clicking on an datastore on a left pane your administrator can see all the resources associated with a specific datastore all the way down to the storage pool where you can see the detailed capacity usage.

Dashboard: Top “N” Consumers

The final dashboard displays the top “N” consumers for individual storage components on a specific storage system. I especially like this one. You can for example, view the top 25 datastores (DPVol LUNs) from IOPs perspective or top 25 datastores consuming storage processing resources. Net-net, now have a view to see the metrics important from VM-Storage infrastructure performance perspective and easily identify the top consumers of your storage resources.

Our intent is that these dashboards enable VI administrators to gain deep visibility into the state of Hitachi storage platforms, including performance metrics, end-to-end resource mapping, and resource utilization. It currently supports our Hitachi Enterprise Storage family and follows the introduction of similar capabilities with our UCP Converged offering. Welcome comments and recommendations on what you what would like to see in upcoming versions to further simplify the operational environment.


This Hitachi Storage Adapter is being made available at no charge and can be downloaded from or VMware Solution Exchange.
