Required if SizingMode is set to USER_PROVISIONED. Specifies the size of the file system's SSD read cache, in gibibytes (GiB).

The SSD read cache size is distributed across provisioned file servers in your file system. Intelligent-Tiering file systems support a minimum of 32 GiB and maximum of 131072 GiB for SSD read cache size for every 4,000 MB/s of throughput capacity provisioned.

sizing_mode instance-attribute 

sizing_mode: NotRequired[LustreReadCacheSizingMode]

Specifies how the provisioned SSD read cache is sized, as follows:

  • Set to NO_CACHE if you do not want to use an SSD read cache with your Intelligent-Tiering file system.

  • Set to USER_PROVISIONED to specify the exact size of your SSD read cache.

  • Set to PROPORTIONAL_TO_THROUGHPUT_CAPACITY to have your SSD read cache automatically sized based on your throughput capacity.
