Ports for the Xgig 3 and 6 Gigabit SAS/SATA Wide-Port/4x blades and the Xgig5000 12G SAS
blade display somewhat differently. Ports are grouped into two banks of four. The first port in the
left bank is logically associated with the first port in the right bank to form a port-pair. Port-pairs
on the blade can be selected individually as narrow links or together as part of a wide link.
40G ports are made from eight 10G ports merged into 40G functionality and displayed as two
ports.
When you select a wide-port/4x blade or any combination of ports in a wide blade, all of the
selected ports are put into a wide link. Click the wide-port/4x blade to add all ports in the blade as
a wide-port link to the domain.
When you click the chassis to select all of the ports, ports in each wide-port/4x blade are placed
into a single, separate wide-port/4x link. If there are other SAS ports in the selected chassis, these
ports will be placed into another single wide link.
Note: The 6 Gigabit SAS/SATA Multi-Function System (Xgig-LXP) and the 6 Gigabit
SAS/SATA Multi-Function blade each have four ports although eight ports are shown in the
chassis view as in the Wide-Port 4x blades, and the port pairs are arranged in the same pattern
as the Wide-Port 4x blades. The four non-operational ports are displayed as blank with a
diagonal line through them as shown below.
Note: The ports in the New Domain area are synchronized to the port selection in the Port
Viewing and Selection
area. Make sure you have selected all ports in the
Port Viewing and
Selection area before customizing links, as the links return to the default configuration when
you modify the port selection. Every time the port selection changes in the
Port Viewing and
Selection area, the New Domain tree gets re-populated with chassis, links, and ports, and the
links are recreated using a default algorithm.
The algorithm for creating the default configuration for links is as follows:
1.SAS/SATA, FC, and GE ports are grouped together consecutively into links of up to 8 ports.
2.Within each domain, links are named consecutively
Link - 1
,
Link - 2
, etc.
3.SAS links are named SAS Link - 1 , SAS Link - 2 , etc.
