Cabling Two PowerVault 22xS Storage Systems to a Cluster SE500W
Connecting the cluster to two PowerVault 22xS storage systems is similar to connecting the cluster to a single PowerVault 22xS storage system. Connect channel 0 of the PERC RAID adapter in each node to the back of the first storage system, as described in "Cabling One PowerVault 22xS Shared Storage System to a Cluster SE500W." Repeat the process for channel 1 on the controller in each node using a second PowerVault 22xS storage system. See Figure
With dual storage systems connected to a single PERC RAID adapter, mirroring disk drives from one storage system to another is supported through RAID 1 and 1+0. To protect the cluster applications and your data if an entire storage system fails, Dell strongly recommends using RAID 1 or 1+0.
NOTE: If you have dual
