Tesng with Iometer showed the performance of compeve products was idencal at real-world 4k, 8k, and 16k block sizes.
However, the QLogic QLE2672 used up to 23 percent less CPU processing power to do the same work.
Performance with Gen 5 Fibre Channel
QLE2672
Tesng by QLogic shows the QLE2672 Gen 5 Fibre Channel Adapter
delivers high IOPS with Microso Windows Server 2012 and
requires signicantly less CPU ulizaon than compeve products.
Real-World Performance and CPU Eciency
When used with a high-eciency Gen 5 Fibre Channel Adapter, Hyper-V with VHDX can provide even larger
performance advantages. In tesng performed by QLogic, the QLogic QLE2672 Gen 5 Fibre Channel Adapter
delivered the same IOPS performance using real-world 4KB and 8KB block sizes for dual-port adapters as the
nearest competor—with 23 percent less CPU ulizaon. This frees CPU cycles for VMs and their
workloads, which is crical for Tier-1 applicaons or in dense VM environments.
