服务器的安全性能要求非常高,主要体现在RAS性能上。RAS性能指的是机器的可靠性(Reliability)、可用性(Availability)和可服务性(Serviceability)。RAS能力主要看几个方面:System 级别的RAS特性、CPU RAS特性、内存RAS特性、I/O RAS特性等。

NUTANIX:超融合架构(简称“HCI”)是指在同一套单元设备中不仅仅具备计算、网络、存储和服务器虚拟化等资源和技术,而且还包括备份软件、快照技术、重复数据删除、在线数据压缩等元素,而多套单元设备可以通过网络聚合起来,实现模块化的无缝横向扩展,形成统一的资源池。HCI是实现“软件定义数据中心”的终极技术途径。

超融合的缺点:
- 性能一致性问题
- 集群达到一定规模后,系统架构复杂性就会非线性增加
