Fibre channel and iSCSI host connections
The storage subsystem fibre channel connection consists of up to four host
fibre-channel loops and a redundant drive fibre-channel loop. The host fibre-channel
loops provide the fibre path for host attachment. They can consist of fibre-channel
cables, SFPs, host bus adapters, fibre-channel switches, and RAID controllers. The
redundant drive fibre-channel loop provides the fibre path from the DS5100 and
DS5300 to the hard disk drives (HDDs) in the storage expansion enclosures. The
redundant drive fibre-channel loop consists of the DS5100 and DS5300, the storage
expansion enclosures, fibre-channel cables, and SFPs.
The DS5100 and DS5300 supports redundant drive channel pair configurations. You
can build a redundant drive channel pair by connecting one or more storage
expansion enclosures to the redundant RAID controllers. Then, use dual fiber-optic
