Cabling Configurations
NOTE The Syncro CS 9286-8e solution does not support booting from a
shared operating system volume.
22. Install the Failover Cluster feature on both servers, following the instructions in the Microsoft documentation.
2.2 Cabling Configurations
This section has information about initially setting up a Syncro CS configuration with one or two JBOD enclosures. It
also explains how to add a second JBOD enclosure to an operational single-JBOD configuration without interrupting
service on the configuration.
System throughput problems can occur if you use the wrong kind of SAS cables. To minimize the potential for
problems, use high-quality cables that meet SAS 2.1 standards and that are less than 6 meters long. See the list of
approved cables and vendors on the web link listed at the end of Section 1.4, Hardware Compatibility.
The following figure shows the SAS cable connections for a two-controller-node configuration with a single JBOD
enclosure.
NOTE In the figures in this section, Top Connector means the external
connector closest to the bracket screw support end of the controller
bracket (connector J1A4 in Figure 2). Bottom Connector means the
other external connector (connector J1B1 in Figure 2).
Figure 5 Two-Controller-Node Configuration with Single JBOD Enclosure
The cross-connections between the controllers provide redundant paths that safeguard against expander, cable, or
expander failure.
To retain consistent device reporting, the corresponding port numbers for both controllers must be connected to a
common enclosure expander. In this example, the top connector on each controllers is connected to Expander A and
the bottom connector on each controller is connected to Expander B.
