What I learned last week: How important NPIV is…

Up until last week I was ashamed to say – that I always thought NPIV (N-Port Virtualization) was merely an obscure and un-utilized (by many) feature of a VM that was introduced in Vi3.5

It wasn’t until I was chatting to some HP guys who work on the HP Blades that the importance of NPIV became apparent to me. I guess this say much about my lack exposure to blade technologies since the very early blades. I’ve been spending too much time with conventional 2U/4U boxes by all accounts. NPIV is critical in blades because each HP enclosure has just 4 FC ports. NPIV allows these ports to broken down into 16 ports one side of the enclosure, and another 16 on the other side – offering up to 32 WWN IDs with NPIV. These in turn can be presented to the blades as separate WWNs.
