Configuring Dynamics GP's (SQL Server) Disks
While I understand you want to follow Microsoft guidelines, in my opinion a lot of the Dynamics best practices are outdated.

I personally don't work with GP but with AX and I tend to follow the SAN vendor guidelines for SQL Server rather than the guidance that Microsoft defined in the days of direct attached storage.

I haven't worked with EMC a lot but they clearly have a SQL Server best practices document which states:


  Most SQL server database environments can benefit from storage pool
  based  configurations


I'd just run some benchmarks before migrating to the new hardware and double-check with the SAN vendor and go with their recommendations.

For example, the recommendation says to use RAID1 for tempdb, but if you can get your hands on some nice NVMe PCI express cards those will perform lots and lots faster even if they aren't the "recommended" setup.
