Vendor Settings:

• Was multipathing / link aggregation used (MPIO, SMB 3.0, etc.)? Link aggregation, SMB3 was used
  
• Caching used (is data cached in storage architecture?) The SSD is a persistent shared storage for read/write caching.
  
• Read/write caching (describe use, size, and how caching works in architecture): In the Qumulo hybrid nodes every block of data written to the file system is persisted to NVMe/SSD and from there is destaged to HDD.  Read caching uses the same SSD’s with algorithms to determine the required read data to be restaged in the cache.
  
• If SMB used for testing, does vendor solution support SMB write-through?  Yes, through settings in the product
• Was SMB write-through enabled during the testing? Yes
• Array deduplication used in testing: No
• Array compression used in testing: No
