Explanation
Shadow Clones is a Nutanix feature specifically designed to optimize read I/O in VDI and other environments where many VMs access the same base disk image (e.g., a shared OS or application image). When Nutanix detects that multiple VMs on different nodes are repeatedly reading the same data blocks, it automatically creates local cached copies (shadow clones) of that data on each node. This eliminates cross-node network reads for common data, dramatically improving VDI boot storm and steady-state performance. Remote/Local Protection Groups (A, B) are for data protection, and Snap Clones (C) are for fast VM provisioning, not read caching.
