BVQ Unified Storage

platform?
With this BVQ Version version we introduce one major step towards a massive easement for connections of BVQ to your Business Intelligence (BI) or IT Systems Management (ITSM) solutions.
...
To address that issue, we created a unified data model with general object types that are linked to specific object types from different platformsof our existing platform specific models. For example a Block Storage Volume of the BVQ Unified Model is linked to a VDsik VDisk of the IBM Sepctrum Spectrum virtualize platform, a LUN of the Netapp NetApp ONTAP platform and a LUN of the Dell EMC Unity platform. The same appears to such an object's attributes and performance statistics of general object types.
All models coexist in BVQ. We The Unified model coexists in parallel to the platform specific models and we still kept the specific models to be as excat exact and near to the platform vendor models as possible. The Unified model coexists to the platform specific models in parallel. With that we can always support any platform specific feature in BVQ without a need to extend or change the Unified model.
BVQ for Dell EMC Unity use cases
BVQ for Dell EMC Unity finds answers to your typical use cases around that platform:
- What dependencies exist between my VMware or IBM PowerVM LPARs and my Unity FC/iSCSI Block storage LUNs (Workload? Capacity?)
- Are there bottlenecks in the internal data flow inside my Unity system (FC or Ethernet ports? Node cache or CPU? Data reduction layers?)
- When do I need to extent my capacity?
- How much capacity of my volumes are distributed on which tier of my pools?
Information gathering
BVQ scans topology and performance informations from the REST API of each Dell EMC Unity storage system.
What information is collected?
...
- Scanned every 10 minutes (default) (10 minute interval averages)
(that will be improved soon) - 3 object types containing a total of ~30 performance statistics
Additional information:
- See Supported Dell EMC Unity systems (SW) for more information about which HMC and Power Systems HW/SW versions are supported.
- See Getting started - Scanner for more Information about BVQ Scanner configuration.
- See Dell EMC Unity preparation for additional Cluster preparation tasks.
- See BVQ for Dell EMC Unity scan data BVQ Offline Scanner information for more details.
In addition a specific model is much more intuitive to understand for a experienced platform expert. The general model is much smaller, simpler and easier to understand for general management purposes. These are major benefits of BVQ in the market, compared to solutions, that desperately try to bring everything under the hat of a single general model.
Unified Model object relations
The first BVQ Unified model released with this BVQ version consists of nine general object types which are linked to specific object types of the following platform specific data models:
Unified Model objekt linking
The Unified model object linking completely depends on the underlying specific object models. For example, if the NetApp model knows which NA Nodes are part of a NA Cluster, the BVQ General Model also knows which Storage Nodes are part of a Storage System.
BVQ Unified model use cases
- What dependencies exist between a generic block volume to Hypervisors as VMware or IBM Power VM (Workload? Capacity?)?
- How can I create a general report about Host mapped capacity without taking care of vendor specific data layouts.
- How can I create a general Splunk or Grafana Dashboard for all my store systems - vendor agnostic?
End to end inter platform relations
The BVQ Dell EMC Unity platform Unified model is interconnected to the following other platform models supported by BVQ. With that all Dell EMC Unity general objects can be combined in an end to end relationship to objects of these platforms.
