Memory  mirroring 
You  can  configure  the  server  to  use  memory  mirroring.  Memory  mirroring  stores 
data  in  two  pairs  of  DIMMs  simultaneously.  If  a  failure  occurs,  the  memory  controller 
switches  from  the  active  pair  to  the  mirroring  pair.  Memory  mirroring  reduces  the 
amount  of  available  memory.  Enable  memory  mirroring  through  the 
Configuration/Setup  Utility  program.  See  the  section  about  using  the
