You must ensure that each Storage Node hosted by a virtual machine has enough space to support the initial configuration and future storage expansion.
If you are using more than one storage volume for each Storage Node, you must assign at least 2 TB to object store 0; however, 4 TB is recommended. Using 4 TB ensures that the Storage Node has adequate capacity for object metadata and that object store 0 can also be used for object data.
The performance of the OS volume and of the first storage volume significantly impacts the overall performance of the system. Ensure that these provide adequate disk performance in terms of latency, input/output operations per second (IOPS), and throughput. Refer to documentation related to performance sizing.
All StorageGRID Webscale nodes require that the OS drive and all storage volumes have write-back caching enabled. The cache must be on a protected or persistent media.
