Single Host PV Links Configuration
Data path redundancy can be achieved with the configuration shown in Figure .
Using an additional host bus adapter and the LVM software, pvlinks can be
created to provide a redundant path to data. A separate mirror path can be created
for data protection, also. This configuration protects against any single
component failure (cables, HBAs, disks). Like the single host basic
configuration, each loop is capable of 200 MB/s which translates to 400 MB/s for
this configuration.
