Overview

Overview

When a service's storage space is insufficient, the storage space needs to be expanded in time. OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage systems provide an online capacity expansion function. When the storage pool is with surplus capacity, you can reduce it to release storage space.

  • Expanding storage space includes expanding storage space for block service and expanding storage space for file service. You can expand disk domain or storage pool, and increase LUN or file system capacity .
    • LUN capacity expansion

      Increasing LUN capacity on servers is complex.
