SC Series support for ReFS and NTFS
Microsoft recommends ReFS for very large data volumes. Because of the reduced feature set available from
Microsoft with ReFS as compared to NTFS, verify the required features before choosing the format type.
Because SC Series is block-level storage, the type of format chosen for an SC Series volume from the
perspective of the OS typically does not matter. ReFS and NTFS work equally well from the standpoint of
snapshots, replication, and data reduction. However, ODX and TRIM/Unmap are not supported on SC Series
storage with ReFS volumes. If ODX and Trim/Unmap integration are needed, then use NTFS.
For more information about ReFS and NTFS, refer to the
Microsoft Windows IT Pro Center.
