How is the first installed expansion enclosure displayed in PowerStore Manager?

• DBus_0_0

• B

• C

• D

Explanation

Option A (Bus_1_0) is correct because PowerStore uses a Bus_X_Y naming scheme where the bus number indicates the expansion bus and the second number is the zero-indexed position of the enclosure on that bus. The first expansion enclosure occupies Bus 1 (the dedicated expansion bus) at position 0 (the first slot, zero-indexed), yielding Bus_1_0.

Bus_0_0 (D) is wrong because Bus 0 is reserved for the base appliance/internal components, not expansion enclosures. Bus_0_1 (B) is wrong for the same reason - it still references Bus 0, which cannot host an external expansion enclosure. Bus_1_1 (C) is wrong because the position index starts at 0, so _1 would indicate the second expansion enclosure on Bus 1, not the first.

Memory tip: Think "1 then 0" - expansion starts on Bus 1, and the first of anything in zero-indexed systems is always 0. The first expansion enclosure = Bus_1_0.
