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 Network Optix NX Witness VMS was configured as described by Network Optix's best practices and operated within the recommended bandwidth, camera count, and other Network Optix maximum requirements. - Configured video storage for a Dell storage system.
- Set up camera simulators (traffic generators) to produce a traffic load to each at the desired bandwidth.
- All camera streams were configured for continuous recording.
- 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 on Isilon nodes
- 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.
