Volumes

A volume is a logical storage space available to a PC. When the volume is allocated on the
virtual disk, it is assigned a size, a drive letter, and a file system.

Using ReFS Versus NTFS

WSS 2012 has two types of file systems: Resilient File System (ReFS) and New Technology
File System (NTFS). NTFS has been the principal file system for Windows implementations
since 1993. ReFS is based on NTFS, but has been enhanced for storage applications.
ReFS offers the following functionality:
• Allows for very large files, volumes, and directories
• Allows for performance using data striping
• Supports disk scrubbing for recovery from latent disk errors
• Stores metadata, such as file attributes, with checksums to allow detection and correction
of most types of disk corruption
• Supports copy-on-write to prevent data corruption from "torn" write tasks. The previous
copy is not written over until the new write is complete.
• Uses B+ trees for performance with both small and large file structures
ReFS cannot be:
• Encrypted using Encrypting File System (EFS)
• Used on a boot drive, removable media, or drives that will be compressed
• Expanded after the volume is allocated
• Used for quota management
If you are using NTFS, you can expand or reduce the volume size.
Create a volume
To allocate a volume:
1. Open Server Manager.
2. After Server Manager has polled the server storage, in the left menu, select File and
Storage Service.
3. Select Disks to display the virtual disks and unallocated physical disks.
4. Select the disk for the new volume.
The system displays the volumes already defined on the disk.
