The purpose-built Unity XT Series systems have three different DAE configuration options:
The 25-drive, 2.5” 2U DAE holds up to twenty-five 2.5” drives (Figure 24). The back of the DAE includes LEDs to indicate power and fault status. There are also LEDs to indicate bus and enclosure IDs.
The 25-drive 2.5” 2U DAE can be powered by AC and is attached to the DPE by mini-SAS HD connectors (Figure 25).
The 15-drive 3.5” 3U DAE is available for Unity XT Hybrid systems and can be powered by AC power and is attached to the DPE by mini-SAS HD connectors (Figure 26).
The back of the DAE includes LEDs to indicate power and fault status (Figure 27). There are also LEDs to indicate bus and enclosure IDs.
The 80-drive 2.5” 3U DAE is available for Unity XT Hybrid and All Flash systems and can be powered using AC power and is attached to the DPE by mini-SAS HD connectors (Figure 28). A high-bandwidth x8 lane SAS connectivity option to the DPE is also available for models that support the 4-port 12Gb SAS I/O module which include the Unity XT 480/F, 680/F, and 880/F. For supported drive types/sizes on the 80-drive DAE, see the Dell Unity Drive Support Matrix on Dell Online Support.
In terms of operating power, the 80-drive DAE operates from 200 to 240V AC at 47 to 63 Hz with a max power consumption of 1,611 VA (1,564 W). For a full listing of power requirements and related hardware information, see the Unity XT Hardware Information Guide on Dell Online Support.
