红帽全球峰会1.2. Active/Passive multipath configuration with two RAID devices
Active/passive configuration with dual RAID devices provides redundant paths to multiple storage arrays, ensuring failover protection across separate RAID systems with dedicated controllers.
In this configuration, there are two HBAs on the server, two SAN switches, and two RAID devices with two RAID controllers each. With DM Multipath configured, a failure at any of the points of the I/O path to either of the RAID devices causes DM Multipath to switch to the alternate I/O path for that device. The following image describes the configuration with two I/O paths to each RAID device. Here, there are two I/O paths to each RAID device.
