configuring the FC IO cards. See the "Storage Center 6.2 System Setup Guide" for more information
on initial setup of the Dell Compellent Storage Center.
In legacy mode, front-end IO ports (in this case FC ports) are broken into primary and reserve ports
based on a fault domain. The reserve port is in a standby mode until a primary port fails over to the
reserve port. In terms of MPIO, this requires twice the IO ports to enable multiple paths. For
redundancy, a primary port connects to one controller, and the reserved port in that fault domain
connects to the other controller. While this is a highly robust failover solution, it requires a large
number of ports.
Dell Compellent introduced virtual ports in Storage Center 5.0. Virtual ports allow all front-end IO
ports to be virtualized. All FC ports can be used at the same time for load balancing as well as failover
to another port. Although a virtual disk can still only be written to from the controller that owns the
disk, virtual ports allow for better performance in terms of failover as the virtual connection can simply
be moved to another physical port in the same fault domain. To use virtual ports all FC switches and
HBAs must support N_Port ID Virtualization (NPIV). See the "Dell Compellent Storage Center Microsoft
Multipath IO (MPIO) Best Practices Guide" for more information on multipathing with Microsoft
Windows 2008 R2 Enterprise.
The two FC switches I am using are Brocade 6505s and the zoning configurations are below. The
WWPNs starting with '10' are the FC HBA WWPNs and the other WWPNs are for the Compellent
storage array.
