E-series storage systems are engineered to facilitate online expansion, allowing you to extend the DDP or volume without interrupting system operations. Although expanding the Disk Drive Pool (DDP) or volume is not expected to cause an outage, it is advisable to conduct such operations during times of reduced activity or within scheduled maintenance windows.
