All disk modules in a LUN musthave the same capacity to fully use the modules’ storage space.RAID 6* A RAID 6 group has an even number of disks. You must bind a minimum of 4disk modules and no more than 16 disk modules. We recommend that youbind 6 or 12 modules for more efficient use of disk space. Write caching ishighly recommended, and read caching is recommended for RAID 6.RAID 5*You must bind a minimum of 3 disk modules and no more than 16 diskmodules. We recommend you bind 5 modules for more efficient use of diskspace.80 EMC Navisphere Command Line Interface (CLI) Reference
