Which three components are required in an MX7000 chassis to allow multiple compute sleds to share access to the same disks in an MX5016s enclosure? (Select 3)

The correct answer is B. Drive-assigned storage configuration D. Cluster-aware Operating System E. HBA 330MMZ. Sharing storage across compute sleds in an MX7000 requires three cooperating layers: a drive-assigned storage configuration (B) maps specific MX5016s drives to the appropriate compute sleds at the fabric level; an HBA 330MMZ (E) provides pass-through SAS connectivity without…

Explanation

Sharing storage across compute sleds in an MX7000 requires three cooperating layers: a drive-assigned storage configuration (B) maps specific MX5016s drives to the appropriate compute sleds at the fabric level; an HBA 330MMZ (E) provides pass-through SAS connectivity without taking exclusive RAID ownership of the drives; and a cluster-aware OS (D) coordinates simultaneous multi-node disk access to prevent data corruption.

Why A (PERC H745PMX) is wrong: A PERC card is a RAID controller - it claims exclusive ownership of attached drives and presents them as RAID volumes, making shared access by multiple hosts impossible. Shared storage requires a pass-through HBA (the HBA 330MMZ), not a RAID controller.

Why C (MX5000s IOM) is wrong: The MX5000s is a network I/O module for fabric/switching connectivity within the chassis, not a component that enables shared storage access to the MX5016s enclosure.

Memory tip: Think "Config → Connector → Coordinator" - you need the storage Configuration (B) to assign drives, the right Connector (E, an HBA not a RAID card) to pass through access, and an OS Coordinator (D) to safely arbitrate multi-node writes. If any one of these three is missing, shared disk access either fails or corrupts data.
