Benefits<br />
This configuration offers the simplicity of managing only one redundant fabric with a single uplink.<br />
Transparent failover is managed by a multipathing I/O driver running in the server Operation System.<br />
This scenario maximizes the use of the VC Fabric uplink ports, reduces the total number of swit<strong>ch</strong> ports<br />
needed in the datacenter and saves money as Fabric ports can be expensive.<br />
Considerations<br />
In a fully populated c7000 enclosure, the server-to-uplink ratio is 16:1; this configuration may result in<br />
poor response time and may require particular performance monitoring attention.<br />
A failure somewhere between VC and the external fabric can disrupt all server I/O operations if a<br />
properly configured multipathing I/O driver running in the server Operating System is not used.<br />
The <strong>SAN</strong> swit<strong>ch</strong> ports connecting to the VC-FC modules must be configured to accept NPIV logins.<br />
Requirements<br />
This configuration requires two VC <strong>SAN</strong> fabrics with two <strong>SAN</strong> swit<strong>ch</strong>es that support NPIV, at least two<br />
VC-FC modules, and at least two VC fabric uplink ports connected to the redundant <strong>SAN</strong> fabric.<br />
