Explanation:
Volumes that are candidates for deduplication must conform to the following requirements:
* Must not be a system or boot volume. (not A)
* Can be partitioned as a master boot record (MBR) or a GUID Partition Table (GPT), and must be
formatted using the NTFS file system. (not C)
* Can reside on shared storage, such as storage that uses a Fibre Channel or an SAS array, or when
an iSCSI SAN and Windows Failover Clustering is fully supported.
* Do not rely on Cluster Shared Volumes (CSVs). You can access data if a deduplication-enabled
volume is converted to a CSV, but you cannot continue to process files for deduplication.
* Do not rely on the Microsoft Resilient File System (ReFS).
* Must be exposed to the operating system as non-removable drives. Remotely-mapped drives are
not supported.

    Volumes that are candidates for deduplication must conform to the following requirements:
    -Must not be a system or boot volume. Deduplication is not supported on operating system volumes.
    -Can be partitioned as a master boot record (MBR) or a GUID Partition Table (GPT), and must be formatted using the NTFS file system.
    -Can reside on shared storage, such as storage that uses a Fibre Channel or an SAS array, or when an iSCSI SAN and Windows Failover Clustering is fully supported.
    -If you’re using Windows Server 2012, don’t deduplicate Cluster Shared Volumes (CSVs). You can access data if a deduplication-enabled volume is converted to a CSV, but you cannot continue to process files for deduplication on Windows Server 2012.
    -Do not rely on the Microsoft Resilient File System (ReFS).
    -Can’t be larger than 64 TB in size. For detailed guidance on determining the maximum volume size for your specific workload and system configuration, see Sizing Volumes for Data Deduplication in Windows Server.
    -Must be exposed to the operating system as non-removable drives. Remotely-mapped drives are not supported.
