when AMD recently introduced their EPYC processors, one of the new features was the support for Secure Memory Encryption. (Some of the desktop variants, such as Ryzen Pro, also included this).
AMD's SME (Secure Memory Encryption) feature was first enabled in Red Hat Enterprise Linux 7.5. This technology uses a single key to encrypt system memory which is generated by the AMD Secure Processor at boot. SME requires enablement in either the system BIOS or operating system. When enabled...

The launchSecurity type='sev' element and its contents enable encryption of the VM's memory contents. 3 When memory encryption is enabled, one of the physical address bits (also known as the “C-bit”) is used to mark if a memory page is protected. The required cbitpos element provid...
If your database contains indexes on enclave-enabled columns using randomized encryption, make sure to enableAccelerated database recovery (ADR)in the database before creating a database backup. ADR will ensure the database, including the indexes, is available immediately after you restore the data...
您要在每台设备上配置最低的引导程序配置,包括集群名称、集群控制链路接口和其他集群设置。启用集群的第一个节点通常成为控制节点。在后续节点上启用集群时,这些设备将作为数据节点加入集群。 控制和数据节点角色 一个集群成员是控制节点。如果多个集群节点同时上线,则控制节点由引导程序配置中的优先级设置决定;优先级...
