Although it is possible to assign the full PowerScale cluster file system to a single XProtect Recorder, the Dell best practice is to use SmartQuotas to segment the single PowerScale file system so that each Recorder has a logical subset view of storage.
While there are three directory-level quota systems, the Dell Technologies Safety & Security Lab only uses the hard limit system during validation testing:
- Hard limit (recommended)
-
- Lets you define a usage limit for strict enforcement and configure notifications. For directory quotas, you can configure storage users view of space availability as reported through the operating system.
- Use the Hard limit quota system to set the video storage as a defined value.
- If necessary, both PowerScale and the XProtect Recorder can add or subtract storage, even if a hard limit quota is set.
- Advisory limit
- Lets you define a usage limit and configure notifications without subjecting users to strict enforcement.
- Soft limit
- Lets you define a usage limit, configure notifications, and specify a grace period before subjecting users to strict enforcement.
