Data compression offload to QuickAssist devices is now enabled as part of BIG-IP Virtual Edition (VE) Cryptographic Offload feature. BIG-IP VE Cryptographic Offload uses the Intel QAT 1.7 SDK. A newer QAT 1.7 SDK v4.4.0 provides code and firmware that fixes several known QAT defects, including a compression defect specific to Lewisburg/Lewis Hill QuickAssist devices.
BIG-IP VE Cryptographic and Compression offload are more reliable. The QAT 1.7 v4.4.0 SDK should be installed on the hypervisor host.
