We used one XtremIO X2 storage array as FC SAN storage to test the SQL Server 2017 databases. The storage layer consists of:
The LAN and SAN design includes redundant components and connectivity at every level to ensure that no single point of failure exists. This design ensures that the application server can reach the database server and the database server can reach the storage array if a component fails. The design provides protection even if a failure occurs in one or more NICs or HBA ports, one LAN or FC switch, one or more XtremIO X2 front-end ports, or one XtremIO X2 X-Brick controller.
