DS8886F expansion frame (model 86E) overview:
The DS8886F supports one expansion frame (model 86E) that can be added to a
base frame (model 986). A minimum of 256 GB system memory and a 16-core
processor is required for the expansion frame to be added.
The expansion frame includes I/O enclosures. You can add up to four High
Performance Flash Enclosure Gen2 pairs to the expansion frame.
The main power area is at the rear of the expansion frame. The power system is a
pair of direct-current uninterruptible power supplies (DC-UPSs) with internal
batteries.
