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 S-1 recorder was configured as described by S-1 best practices and operated within the recommended bandwidth, camera count, and other S-1 SVMS maximum requirements. - Configured video storage for a Dell storage system.
- Set up camera simulators (traffic generators) to produce a traffic load to each S-1 recorder at the desired bandwidth.
- Verified that Recording is set to use the H.264 codec and the resolution is set to 30 FPS (1280x720).
- 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 SmartFail
- 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.
