A customer would like to deploy a clustered File Module option on their Hitachi Unified Storage system. What is a valid connection for the cluster interconnect?

Question

Options

• A1Gb Ethernet
• B16Gb Fibre Channel
• C10Gb Ethernet
• D8Gb Fibre Channel

• A
  6% (2)
• B
  3% (1)
• C
  89% (32)
• D
  3% (1)

Explanation

10Gb Ethernet (10GbE) is the required connection type for the cluster interconnect on the Hitachi Unified Storage (HUS) File Module cluster, as Hitachi's architecture specifications mandate this interface for the high-speed, low-latency communication needed between cluster nodes. Option A (1Gb Ethernet) is incorrect because it lacks sufficient bandwidth for cluster heartbeat and synchronization traffic at scale. Options B (16Gb FC) and D (8Gb FC) are wrong because Fibre Channel is a storage fabric protocol used for back-end disk connectivity, not for cluster node-to-node interconnects - mixing these up is a common distractor. Memory tip: Think "cluster interconnect = network fabric = Ethernet, and NAS clusters need speed, so 10Gb wins over 1Gb" - if you see Fibre Channel in a cluster interconnect question, it's almost always a trap targeting storage-network confusion.
