2: Connecting to a Host and Powering On and Off
as a host-attached JBOD enclosure, the copper cable/SFP assembly can be replaced with
optical SFPs and optical cables.
To connect the storage system to a host, insert an optical cable (with SFP) into the
connector labeled “Host 0.” Connect the other end of the optical cable to the FC-AL port
on the host.
In addition to cabling directly to an HBA in a host, you can connect the storage system
to an SGI Fibre Channel 8-port or 16-port switch (using an optical cable and an optical
GBIC). See Table A-10 on page 108 for information on these cables.
Note: The I/O module current limit is 1.5 A.
The host ports of the RAID controller can be connected to a switched-fabric Fibre
Channel Arbitrated Loop (FC-AL) or directly to a server in a point-to-point
configuration. A FC-AL provides shared bandwidth among the attached nodes; as
additional nodes are added to a loop, the bandwidth available to each node decreases.
Fibre Channel switched fabrics are interconnected with switches that increase
bandwidth as nodes and switch ports are added to the system. The bandwidth available
to each node in a switched fabric always remains constant. Unlike previous versions of
the TP9100, which only support FC-AL topologies, the FFx-2 RAID controller host ports
of the 2 Gb TP9100 can implement the behavior of a N_Port when connected in a
point-to-point topology with a server, or when connected to a F_Port on a switch.
In FC_AL topologies, the FFx-2 RAID controller uses NL_Port behavior to connect to
FL_Ports on hosts or switches. After a 2Gb TP9100 boots up, it initiates a log-in sequence
and automatically determines which topology and the protocol should be used, as
dictated by the environment. The topology and protocol are determined by the
preferences of the connecting devices and the internal topology of the 2Gb/s TP9100. For
example, if the system is in multi-target id mode (MTID) then it will connect as an FC_AL
device to ensure that bandwidth is shared equally across the loop. If the system is in
multi-port mode it will attempt to connect as a point-to-point topology in order to
provide the largest amount of bandwidth possible to each host. When the system is in
MTID mode, it can also connect as a FC-AL device depending on the other devices are
connected.
Note: Host FC-AL topologies on both the 1 Gb TP9100 with the FFx RAID Controller and
2 Gb TP9100 with FFx-2 RAID controller support fabric.
