The storage bandwidth test evaluated video storage and applications with a number of different Dell storage systems . Additional tests evaluated ESXi host hardware in relationship to vCPU settings and the resulting bandwidths.
These tests assumed that Cognyte Symphia VMS was configured as described by Cognyte 's best practices and operated within the recommended bandwidth, camera count, and other Cognyte maximum requirements. - Configured video storage for a Dell storage system.
- Set up camera simulators (traffic generators) to produce a traffic load to each Cognyte Recorder at the recommended bandwidth.
- Verified that motion detection was in the On state for all cameras.
- Evaluated the network and video storage to ensure an error-free environment at the induced bandwidth.
- Introduced storage device errors including:
- Disk failures and rebuilds on Isilon nodes
- Initiation of Isilon node failures and recoveries
- Initiation of Isilon node removals (downsizing a cluster)
- Initiation of Isilon node additions (scaling up)
- NIC failures with active/active and active/passive configurations
- Captured the storage system and host statistics.
- Based on the test results:
- If no issues were detected, incremented the bandwidth.
- If issues were detected, decreased the bandwidth.
This procedure was repeated until the maximum error-free bandwidth was determined.
