Our take on the HP P16811-B21 Fibre Channel Host Bus Adapter for Blade system C-Class

The HP P16811-B21 is a 16 Gb Fibre Channel host bus adapter built for HP BladeSystem C-Class enclosures. It fits in a blade's mezzanine slot and links that blade to a SAN at 16 Gb line rate, doubling the 8 Gb adapters it replaced. It is a server-side part for IT teams running or expanding a C-Class blade estate on 16 Gb FC fabrics. Compared with current 32 Gb HBAs it is older and slower, but it matches existing 16 Gb switches and arrays without a fabric upgrade.

Questions and answers

What is the HP P16811-B21?
It is a 16 Gb Fibre Channel host bus adapter that installs in a mezzanine slot of an HP BladeSystem C-Class blade. It connects that blade to a Fibre Channel SAN.
Which servers does it fit?
It is made for HP BladeSystem C-Class enclosures and their blades. It is not a stand-alone PCIe card for rack or tower servers.
Is it worth it over an 8 Gb HBA?
If your switches and storage support 16 Gb, it doubles the link rate and suits bandwidth-heavy workloads. If your fabric is 8 Gb, the extra speed goes unused.
Should I buy 16 Gb or 32 Gb?
Choose 32 Gb only if your switches and arrays support it. On a 16 Gb fabric this adapter matches the rest of the path and avoids paying for unused speed.
What do I need to get it working?
A supported C-Class blade, a free mezzanine slot, and a 16 Gb FC switch port with cabling to your SAN. Drivers come from HP's support site.
Where is the HP P16811-B21 Fibre Channel Host Bus Adapter for Blade system C-Class cheapest?
