  The most important thing to do on a client with so many files is to make sure that the file cache is sized appropriately. The file cache is responsible for the vast majority (>90%) of the performance of the Avamar client. If there's a file cache

  miss, the client has to go and thrash your disk for a while chunking up a file that may already be on the server.

  So how to tune the file cache size?

  The file cache starts at 22MB in size and doubles in size each time it grows. Each file on a client will use 44 bytes of space in the file cache (two SHA-1 hashes consuming 20 bytes each and 4 bytes of metadata). For 25 million files, the client

  will generate just over 1GB of cache data.

  A. 1.0 TB
  B. 1.3 TB
  C. 2.6 TB
  D. 3.9 TB

  ---

  For Gen4 3.9TB node: Raw capacity is 6 TB and licensed capacity is 3.9 TB For Gen4 7.8 TB node: Raw capacity is 12 TB and licensed capacity is 7.8 TB So, In a RAIN config with 1 utility node and 4 storage nodes (7.8 TB), the total capacity should be 48 TB and total licensed capacity is 31.2 TB
