Summaries and Symptoms
This patch includes the following changes for ESX 3.5 Update 3:
- Updates QLogic HBA firmware (4G and 8G) to 4.03.02.
- Adds a new performance feature, interrupt coalescing with QLogic 4G HBAs. This feature reduces CPU utilization (and CPU cost per I/O) and improves throughput of I/O-intensive workloads by generating a single interrupt for a burst of Fibre Channel frames, when received in a short period of time, rather than interrupting the CPU each time a frame is received. This feature is enabled by default.
None beyond the required patch bundles and reboot information listed in the table, above.
