Nblade.cifsNonAesNiBytesProc:Excessive SMB3 cryptographic processing load このメッセージは、ONTAP イベントログに記録されます。

Node: AFF-N1 Time: Tue, May 03 20:44:54 2022 -0400 Severity: ALERT Message: Nblade.cifsNonAesNiBytesProc: Excessive SMB3 cryptographic processing load (AES-NI instruction set is not supported). Description: This message occurs when a system with CPUs that do not support the AES-NI instruction set is performing SMB3 encryption or signing of a large amount of data. These cryptographic operations can degrade performance severely for both SMB and other system operations. Corrective Action: Avoid encrypted or signed SMB3 traffic on systems that do not support the AES-NI instruction set. Source: SMBOffloadPool_00 Sequence#: 1065458
