Storage configuration
12 65TB Data Warehouse Fast Track Reference Architecture for Microsoft SQL Server 2017 using Dell EMC
PowerEdge R640 and Dell EMC PowerVault ME4024 | 3918-RA-SQL
4 Storage configuration
4.1 Cabling
The hardware components were connected using Dell EMC best practices.
In a direct-connect configuration, each HBA should have one port connected to the top storage controller and
the other port connected to the bottom storage controller (see Figure 3).

4.2 Storage pools
Two virtual storage pools were created with twelve disks each and assigned a data protection type of RAID-5.
RAID-5 data protection is used for this solution because it provides maximum capacity while still maintaining
great read performance.
With the ME4 Series, a storage pool is owned by a single controller. Therefore, creating two storage pools
allows the workload to be distributed across both controllers.
