Setting up High Availability (HA) and Failover
In the 7000 Series Flash Storage Platform, Memory Gateway A (MG-A) is the primary server for its
devices, while Memory Gateway B (MG-B) serves as the secondary server. When both MGs are
available, devices created on A accept I/O through Memory Gateway A only, and vice versa.
If Memory Gateway A fails, Memory Gateway B takes over MG-A’s devices and accepts I/O for
those devices. Once MG-A comes back up, failback must be manually for MG-A to start accepting
I/O. Complete the steps in the following sections to set up HA.
