Explanation
Creating a dedicated storage container for the SQL VM (D) allows the administrator to tune storage policies specifically for SQL workloads-for example, disabling inline compression and deduplication, which add CPU and latency overhead that is particularly detrimental to OLTP workloads that perform many small, random I/Os. Migrating the SQL VM's vDisks to this optimized container isolates it from other workloads and removes latency-inducing features. Adding CPU/Memory to the CVM (A) addresses compute bottlenecks on the storage controller, not storage policy tuning. Adding Volume Groups (B) provides iSCSI block storage but does not directly resolve policy-induced latency. Adding vCPU/RAM to the VM itself (C) improves compute resources, not storage throughput.
