An administrator is configuring a fully populated MX5016s storage sled to be accessed by four MX740c compute sleds. Each compute sled has an H745P Jumbo PERC installed. The disks in the storage sled…

Explanation

Option D (16) is correct because in a Drive-Assigned storage configuration, each compute sled's H745P PERC controller connects to the MX5016s through the chassis SAS fabric - which broadcasts all drive presence to every connected host. Since the fully populated MX5016s contains 16 drives, every compute sled's PERC can detect all 16, even though the drives are logically divided into four equal groups of four for management and RAID purposes. The critical distinction is that detection (physical visibility via SAS expander) is separate from assignment (logical ownership by a given compute sled).

Why the distractors are wrong:

• C (4) is the most tempting trap - 16 drives ÷ 4 sleds = 4 assigned drives per sled, but the question asks what can be detected, not what is managed.
• B (2) and A (1) have no architectural basis in this configuration and are implausible given 16 total drives spread across four controllers.

Memory tip: Think "SAS sees all, RAID rules only its own." The SAS expander in the MX5016s makes all 16 drives visible to every PERC; Drive-Assigned mode is just the policy that determines which drives each sled owns, not which ones it can see.
