In Figure 3-48, the Fibre Channel switches are not connected together. Each switch forms its own SAN
fabric.
Connecting iSCSI hosts to the DS3500
The DS3500 can support up to 64 hosts, depending on the number of host ports and host partitions that
are used on the controller. To protect against the loss of any one path from the host servers to the storage
subsystem, use redundant host connections.
