Create pools and volume groups

You create storage capacity to logically group a subset of drives together in the storage array using pools or volume groups, or both.

  • Create pool automatically
    You can create pools automatically when the system detects at least 11 unassigned drives or it detects one unassigned drive that is eligible for an existing pool. A pool is a set of logically grouped drives.
  • Create pool manually
    You can create a pool manually if your setup does not meet the requirements for automatic pool configuration. A pool is a set of logically grouped drives.
  • Create a volume group
    You can create a volume group for one or more volumes that are accessible to the host. A volume group is a container for volumes with shared characteristics such as RAID level and capacity.
  • Add capacity to a pool or volume group
    You can add drives to expand the free capacity in an existing pool or volume group.
  • Create SSD Cache
    To dynamically accelerate system performance, you can use the SSD Cache feature to cache the most frequently accessed data ("hot" data) onto lower latency Solid State Drives (SSDs). SSD Cache is used exclusively for host reads.
