• RAID-6 (double- and triple-parity) and optional RAID-6 across disk shelves

• Active-active clustering for high availability: See Appliance Cluster Configuration

• Link aggregations and IP network multipathing for network failure protection: See Network Configuration

• I/O Multipathing between the controller and disk shelves

• Integrated software restart of all system software services: See Appliance Services

• Phone Home of telemetry for all software and hardware issues: See Phone Home Configuration

• Lights-out Management of each system for remote power control and console access
