BVQ for Dell EMC Unity Platform
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?
- Topology configuration information
- Scanned every 1 hour (default)
- 10 object types containing a total of ~325 attributes:
Systems, Nodes, Pools, Tiers, SAN ports, Volumes, Hosts, ...
- Performance statistics
- Scanned every 10 minutes (default) (10 minute interval averages)
(that will be improved soon) - 3 object types containing a total of ~30 performance statistics
- Scanned every 10 minutes (default) (10 minute interval averages)

End to end inter platform relations
The BVQ Dell EMC Unity platform model is interconnected to the following other platform models supported by BVQ. With that all Dell EMC Unity objects can be combined in an end to end relationship to objects of these platforms.
Remote platform | Remote object | Dell EMC Unity object |
---|---|---|
IBM PowerVM | System / VIOS PV | LUN |
VMware vSphere | SCSI volume | LUN |
Brocade / Cisco SAN | Node port | FC port FC Host initiator |
Brocade / Cisco SAN | Zone Member | FC port FC Host initiator |
Object types
The following overview shows the elementary relationships of physical and logical objects:
Legend: Gray colored objects are visible, light gray invisible, red bordered ones contain performance statistics
BVQ Expert GUI representation
All objects, attributes and statistics of this platform can be interactively browsed within the BVQ Expert GUI.
Where to find Dell EMC Unity objects?
Similar to all other objects, they show up in the Path browser inside the property panel of the BVQ Expert GUI.

Object attributes
BVQ displays all interesting attributes provided. Please explore the BVQ Unity Table view favourites to get an impression of the most important attributes.
Performance and error statistics
The BVQ Dell EMC Unity module gathers major important statistics delivered from the Unisphere API.
Typical questions around performance, load and utilization are answered by BVQ:
- Which LUNs or Pools are overloaded and show high latencies?
- Is there a congestion at an attached SAN port?
- Which LUNs put heavy load on my system?
- Does an latency peak have influence on the performance of a Pool?
- Is the FC host performance affected by slow drainers in the SAN?
- What Volume causes peak overloads in my Pool?
To view performance statistics for one or multiple objects, simply select the objects and open the performance view. There you can choose the metrics you are interested in from the properties panel:
