Various parameters on the ECS EX3000 were tuned to optimize the bandwidth performance with safety and security video traffic. ECS performance tuning in the Dell Technologies Safety & Security Lab is based on the Milestone Recorders using a video file (object) size of 500 MB.
The following table shows the updated parameters and settings:
Parameter | Default value | Tuned value |
com.emc.ecs.chunk.gc.repo.partial.task.generator.max_pending_task_num | 50 | 200 |
com.emc.ecs.chunk.gc.repo.verification.new_run_interval | 6 hours | 30 minutes |
