Chapter 2 Installing the System 31
Redundant Fibre Channel (FC) ports located on the two I/O panels of the service
panel are reserved for data host connections. A system can be configured for 16 FC
or 32 FC ports. A 16-FC port configuration includes two storage resource card (SRC)
sets, each consisting of two SRC processor cards and two storage I/O (SIO) cards.
You can add more FC ports to the system by installing additional SRC sets.
With a 16-FC port configuration, use the four leftmost ports (ports 1 through 4) of
the lower I/O panel to connect data hosts. The four rightmost ports (ports 5 through
8) are connected to arrays in the system.
Port connections are typically evenly allocated between data hosts and arrays.
However, you can allocate additional ports for either host or array connections,
depending on the needs at your site. If you need additional ports for host
connections, refer to “Selecting Ports for Additional Host Connections” on page 33
for guidelines. If you need additional ports for array connections, refer to “Selecting
Ports for Additional Storage Connections” on page 34 for guidelines.
Note – If you allocate more than half of the available ports for SAN or DAS hosts,
you will need an additional 1-meter LC-to-SC cable for each HBA port to physically
connect the DSP to the service panel.
