Which pair of IP addresses is assigned to the Hitachi Unified Storage system maintenance LAN ports by default?

Question

Options

• A10.0.0.16 and 10.0.0.17
• B10.1.1.16 and 10.1.1.17
• C192.168.0.16 and 192.168.0.17
• D192.168.1.16 and 192.168.1.17

• A
  89% (16)
• B
  6% (1)
• C
  6% (1)

Explanation

Hitachi Unified Storage (HUS) systems use 10.0.0.16 and 10.0.0.17 as the factory-default IP addresses assigned to the maintenance LAN ports (SVP/Service Processor ports), making option A correct. Options B, C, and D are plausible-looking addresses but are not the Hitachi-defined defaults - they use either a different third octet (1.1.x or 0.x vs 0.0.x) or the 192.168.x.x private range entirely, which Hitachi reserves for other management interfaces on some products, not the maintenance LAN. The key distinction is that Hitachi specifically chose the 10.0.0.x subnet with host addresses .16 and .17 for the maintenance LAN to avoid collisions with common customer networks that often use 192.168.x.x or 10.1.x.x ranges.

Memory tip: Think "maintenance = minimal" - the default uses the simplest possible 10.x address (10.0.0.x), and the ports start at .16 because earlier addresses in that subnet are avoided for conflict prevention. If you remember "10-zero-zero, sixteen/seventeen," you've got it locked.
