Multiple workspaces created for regression runs can overwhelm traditional lers when they write back regression results and log files.
The team installed a WarpStor appliance in front of their SAN. All regression workspaces were built on the WarpStor appliance. Filer write performance was improved dramatically:
- Up to 10x reduction in random writes due to buffering/coalescing on WarpStor Appliance
- Up to 20% improvement in raw throughput of random writes
- Utilization of the filer reduced by almost 50% during write bursts
- Total IOPs down by more than 70% during write bursts
