hi all! I have a very low level query. Please help to clarify it.
To store data on a storage cluster, at the bottom, there is a heterogeneous set of storage disks,in which there can be a variety of storage disks, such as SSDs, HDDs, flash drives, tapes and any other type also. Document says that provider view this heterogeneous set of storage disks as a single pool. My question is: #1. how does the provider come to this abstraction layer to view different storage disks as a single storage? #2. Is it a part of storage virtualization? #3. are there any set of APIs to interact with this heterogeneous set of storage disks? Please somebody reply. Regards Pragya Jain
