适用场景

  • ONTAP 9
  • NetApp 基于硬件的加密
    • NVMe SED 驱动器(未通过 FIPS 140-2 认证)
    • NetApp 存储加密( NSE )( FIPS 140-2 2 2 级认证)

问题解答

NetApp 存储加密( NetApp Storage Encryption , NSE ),全磁盘加密可用于 FIPS 140-2 2 级自加密驱动器( SED )。对于未获得 FIPS 140-2 认证的 NVMe SED ,也可以使用全磁盘加密。

NSE NVMe SED
整个磁盘已加密 整个磁盘已加密
AES 256 加密 AES 256 加密
板载或外部密钥管理 板载或外部密钥管理
与外部密钥管理器结合使用时,已验证 FIPS 140-2 级别 2 ; FIPS 级别取决于密钥管理器的使用和实施情况 无 FIPS 140-2 认证
所有驱动器(包括 HA 配对)都必须是 NSE 驱动器;不能混用 NSE 和
非 NSE 驱动器
您可以混用 NVMe SSD 和 NVMe SED ,但不能混用 NSE 驱动器
