Figure 2-6 Example host interface daughter card module
Both the single and the dual controller models of the DS3500 storage servers can be
upgraded to include an optional host interface daughter card. When dual controllers are
installed both controllers must be equipped with the same daughter card option to enable the
support of the controller failover functions.
Figure 2-7 shows the SAS optional daughter card installed in the controller. With this option
the subsystem will have up to eight 6Gbps SAS connections for host attachments. For details
on the cabling and use of with the bladecenter and standalone environments see 4.8, “Host
attachment” on page 110.
