业务永续－数据中心的业务连续性规划与设计 这个世界比过去有着更多的风险 环境在不断变化 风险接触范围在不断扩大 全球及区域间的依存关系在不断增大 供应链每时每刻都存在中断的风险 业务中断将导致更大的影响 宕机可能导致更大的财务影响 宕机可能对品牌造成伤害 宕机可能导致数据失去完整性 更繁杂的规范 产业和监管标准在不断变化 产业分工在地理分布上更趋分散 每个国家都可能有自己相应的规范 更多的灾害 经济危机、恐怖主义、飓风、地震、 停电、火灾和疾病的大规模威胁 灾难的分类 业务连续性问题和挑战 HA和DR 的差别 支持业务连续性与灾备的系统组件 面向开放平台的高可用(High Availability)解决方案的架构 Availability by 应用 按照高可用的要求来设计应用架构 Availability by 中间件 DB2 HADR、WAS 集群, CICS 集群 Oracle RAC Availability by 操作系统 AIX LVM 镜像、HACMP for AIX Availability by 硬件冗余 服务器 冗余的处理器 / I/O适配器卡/ 电源 / 内置磁盘RAID技术保护 外置磁盘, I/O 总线、SAN 交换机、LAN、LAN 交换机 冗余的部件 磁盘 RAID 多路径(Multi-Path)软件（SDD、RDAC) 通过磁盘复制的可用性 FlashCopy, Metro/Global mirror 网络 IBM Power Systems High Availability Solution Do you want more availability and less work on weekends? IBM Power Systems RAS架构 Primary POWER RAS Features Primary POWER RAS Features - Continued World-class Hardware RAS High Availability Hardware - Live Partition Mobility Live Partition Mobility with POWER6* Continuous Application Availability With Live Partition Mobility and Live Application Mobility, planned outages for hardware and firmware maintenance and upgrades can be a thing of the past Workload Balancing with Live Partition Mobility* As computing needs spike, redistribute workloads onto multiple physical servers without service interruption High Availability Operating System  - AIX UNIX Reliability, Availability and Serviceability The “Number One” Customer Requirement AIX Storage Keys AIX 6 Concurrent Maintenance AIX 6 dynamic tracing with probevue Trace existing programs without recompiling Dynamic placement of trace probes For debugging and performance analysis Tracable Calls: AIX system calls, application functions, and application calls to library functions Dynamic tracing language called Vue Initial support only for “C” programs 操作系统停机时间调查: AIX是业界最稳定的操作系统(27个国家400个用户) AIX is “Most Reliable” According to a recent Yankee Group study* of 400 Windows, Linux and UNIX users, AIX was the most reliable server operating system:
