Dell Avamar Virtual Edition (AVE) performance is highly dependent on I/O throughput. Using thin provisioned disks introduces latency, especially on first write to a new block, as space must be allocated and zeroed on demand. This leads to inconsistent and degraded performance compared to the recommended thick provision eager zeroed configuration. Consequently, any performance benchmarks conducted on a thin-provisioned AVE will not reflect the system's true capabilities in a properly configured production environment, rendering the results inaccurate for capacity and performance planning.

B. Avamar capacity is determined by the AVE license and configuration (e.g., 0.5 TB, 1.0 TB), not the underlying virtual disk provisioning type.

C. Thin provisioning generally results in slower, not faster, disk performance for I/O-intensive applications like Avamar due to the overhead of on-demand allocation.

D. The virtual disk provisioning method has no direct impact on the virtual machine's memory (RAM) requirements, which are determined by the AVE size.
