HANA SR HA architecture
SAP HANA Solution Architecture
1.The database layer employs 2 R750 servers, deployed in a Scale-up architecture; each server has 1.5TB of memory. In case of any server failure, it will automatically switch to the backup server to ensure uninterrupted operation of the business for 3 years, 7 days a week, 24 hours a day.
2. The production server is equipped with the DELLEMC R750 model, which is a certified integrated machine for SAP HANA. It offers 3-year 7*24-hour service.

备份系统重要组件 Avamar 介绍
业内第一的源端重复数据消重，网络带宽降低99%，存储空间降低95%，备份时间缩短90%
- 虚机Image备份：
– 无代理备份模式，对生产零影响
– 增量备份和恢复，支持已更改数据块跟踪 (CBT)
– 细粒度恢复（任意恢复虚机内部某一个文件）
- 虚机代理备份：
– 代理级备份还可以保障其它类型应用或数据库如Oracle RAC的一致性
– 可以安装代理，意味着可以支持物理机备份
- 备份数据流自动负载均衡：
– 代理之间自动负载均衡
– 按照容量和性能进行自动匹配
