Description: Cisco UCS equipment:SlotArray:numberOfOnboardDisks managed object property

What is cucsEquipmentSlotArrayNumberOfOnboardDisks?

This reports how many onboard (non-hot-swap, typically motherboard-mounted M.2 or fixed SATA) disks this server model has, separate from its hot-swap front bays. Because onboard disks are addressed and reported differently from the hot-swap bays covered by numberOfSlots, UCS Manager needs this separate count to build a complete storage inventory picture for the server, including drives an admin can't see or swap from the front panel. A rack server might report numberOfOnboardDisks of 2 for a pair of internal M.2 boot drives, in addition to 24 hot-swap bays counted separately by numberOfSlots.
