• A quad port Fibre Channel HBA (connects to DX-Series storage
arrays)
The DX100 contains the following Fibre Channel HBAs:
• Four dual port Fibre Channel HBAs (connects to customer Fibre
Channel network)
• Two quad port Fibre Channel HBA (connects to DX-Series storage
arrays)
This connection can be a direct connection to the Fibre Channel host or to
a Fibre Channel switch. The Fibre Channel interface automatically detects
the mode being used by the network and sets itself appropriately.
Fibre Channel Switch
(DX100 Only)

The Fibre Channel switch provides twenty ports for connecting up to
eight storage arrays to the DX-Series controller. Each storage array has
two connections to the Fibre Channel switch for redundancy and
improved performance. One Fibre Channel switch is required for two to
eight storage arrays; a second Fibre Channel switch is required for nine to
sixteen storage arrays (see
figure 5
).
