- ONTAP 9
- Clustered Data ONTAP
- Data ONTAP operating in 7-Mode
- CIFS Home Directories
- User profiles can be in used in VDI (Hyper-V) or Citrix Home Profiles using folder redirection.
- Higher than expected CIFS "other" protocol latency. High Latency due to Data Processing delays (Dblade).
- Primary CIFS operations impacted will include readdir, open, close, getattr, lookups.
- If OCUM is in use, the delay will show up as "data processing" coupled with high Other Latency. Typically reported in the 100's of milliseconds range.
- Single volume user directory count and data layout may have stale user folders or is a deep \ wide directory structure containing many thousands of users.
