Dell POWEREDGE R720 - Manual (Page 15)

Microsoft SQL Server 2012 Fast Track Reference Configurations using PowerEdge R720 and PowerVault MD3620i
15
For Fast Track architectures, Dell recommends using mount points for the storage access rather than
using drive letters. It is also important to assign the appropriate LUN/volume and mount point names
to the configuration in order to simplify troubleshooting and performance analysis. The mount point
names should be assigned in such a way that the logical file system reflects the underlying physical
storage enclosure mapping. Table 4 shows the LUN and mount point names used for the specific
reference configuration and the appropriate storage layer mapping. All the logical volumes were
mounted to the
C:\FT folder.
