A server administrator is deploying a VMware vSphere cluster and configuring High Availability on a PowerEdge MX7000 modular system. Which configuration is required?

Question

Options

• APERC MX745P
• BEnclosure-assigned storage
• CSAS IOM setup in redundant mode
• DDrive-assigned storage

• A
  10% (3)
• B
  83% (24)
• C
  3% (1)
• D
  3% (1)

Explanation

Enclosure-assigned storage is correct because VMware vSphere HA requires shared storage accessible by multiple hosts simultaneously. In the MX7000 modular system, enclosure-assigned storage presents drives at the chassis fabric level, allowing any compute sled in the enclosure to access them - which is exactly what HA needs to restart VMs on a surviving host after a failure.

Why the distractors fail:

• (A) PERC MX745P is a RAID controller card - useful hardware, but a controller alone doesn't create shared storage; it just manages drive arrays locally.
• (C) SAS IOM in redundant mode provides path redundancy for fault tolerance in connectivity, but redundant paths don't make storage shared across compute nodes, which is the HA requirement.
• (D) Drive-assigned storage is the opposite of what's needed - it binds drives directly to one compute sled, so if that sled fails, no other host can access the data, breaking HA entirely.

Memory tip: Think "HA = Share, not Own." Drive-assigned = one server owns the storage (no HA). Enclosure-assigned = the chassis shares the storage (HA works). The answer lives at the enclosure level because HA operates across multiple hosts.
