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 Honeywell DVM was configured as described by Honeywell's best practices and operated within the recommended bandwidth, camera count, and other Honeywell maximum requirements. - Configured video storage for a Dell storage system.
- Configured Honeywell Recorders for the storage protocol to be tested (FC, iSCSI, SMB).
- Set up camera simulators (traffic generators) to produce a traffic load to each Camera server at the desired bandwidth.
- Evaluated the network and video storage to ensure an error-free environment at the induced bandwidth.
- Introduced storage device errors including:
- 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.
The test results associated with the previous procedure, for each tested Dell storage array or cluster, are presented in Dell Storage with Honeywell DVM: Configuration Guide. The test results provide information about the maximum expected bandwidth per array or node, the disk configuration, as well as recommendations for various configuration parameters derived from extensive testing.
