High Availability, Disaster Recovery 和 Data Distribution for IBM i
Focus your time 和 efforts on building 你的业务, not worrying about downtime 和 data loss
Protecting 你的业务 starts with preventing data loss 和 corruption. Keeping your IBM i systems 和 applications up 和 online keeps 你的业务 moving. HA/DR solutions are absolutely the best way to meet those critical requirements.
但是，不要认为投资HA/DR解决方案就像购买保险策略，只有当您的业务避免了痛苦的停机或数据丢失时，它才有价值. 如果您能够利用其核心复制和数据完整性功能提供绝对最新的服务，那么HA/DR解决方案每天都可以提供真正的价值, accurate 和值得信赖 data to your analytics systems, 决策者, 和业务合作伙伴, 无论何时何地，只要他们需要.
精确的’s Assure HA/DR solutions let you do all that, providing the ultimate in protection against data loss 和 corruption, ensuring resilient business continuity, 和 enabling truly reliable analytics 和 empowered decision making.
Developed 和 refined over more than 30 years, 确保IBM i的HA/DR解决方案建立在IBM i核心复制能力的传奇力量之上, 提供灵活的, reliable data protection 和 availability capabilities for businesses of every size.
The key technology underlying effective DR solutions is real-time replication, 位系统的准确性. 但是仅仅复制是不够的:只有在站点外维护数据的备份或副本，才能实现对灾难中数据丢失的真正保护, in a separate location that won’t be affected by any event that destroys the production data. 现实也是一样的, 无论您的业务运行在一个或两个入门级IBM i服务器上，还是使用企业规模的IBM i系统跨越多个数据中心.
准确的保证 HA/DR solutions offer complete, full-featured DR protection scaled to fit every business size 和 data protection requirement. Assure solutions fully leverage IBM’s powerful 和 secure Remote Journaling, 为所有对象和数据添加必需的关键特性和功能，包括持续复制监视和自修复, 轻松定制, automated configuration 和 management 和 much more.
在今天的24×7, 不间断, 依靠互联网的世界, the rules are the same for every business, large or small: If your IBM i systems 和 data are not continuously available, 你的生意有风险. 顾客不喜欢等待, 和 with access to your competitor’s goods 和 services just a few clicks away, they can just hit the “back” button 和 do business elsewhere.
与此同时, 严格的政府和行业法规以及与关键合作伙伴和内部客户的服务水平协议意味着任何停机时间, 计划内或计划外, 会有严重的后果.
精确的’s Assure HA/DR solutions all have the power 和 flexibility to ensure smooth, reliable switching to avoid planned downtime for server or network maintenance, 升级, 数据库重组等. And failover in response to unplanned problems is always fast 和 reliable, whether you maintain close control of each step or automate for instant, 定制的, 和无人保护.
企业规模越大, the more critical it is that data is accurate, 一致的, 和值得信赖, 整个企业. Data needs to flow through multiple channels 和 between geographically dispersed data centers, instantly moving to where it is needed for business analytics 和 secure transactions.
Deploying 和 managing such complex, distributed computing operations is challenging. Protecting them against data loss 和 downtime can be even more so. 在多个位置的服务器之间平衡工作负载当然可以优化计算能力并减少资本支出. But it also creates multiple potential HA/DR vulnerabilities that need to be addressed.
例如, when operations depend on two servers replicating in an active-active setup, you have to be ready to respond if one of those servers goes down in a regional disaster, 并且还准备了一些过程，以便在发生此类灾难时保持业务运行，同时pair中的另一个服务器脱机进行计划维护.
确保HA/DR复制解决方案提供了一种无限制的可伸缩性，使实时数据分布的最复杂的企业拓扑成为可能, as well as the powerful features for automating configuration, 监控, 和 daily management that make it possible for mere humans to support it all.
最重要的是, 确保HA/DR解决方案具有配置和自动化多冗余的所有特性和灵活性, worst-case scenario protection such globally distributed operations require.
For any business that relies upon IBM Power HA® SystemMirror for IBM i or IBM Db2® Mirror for i, 通过与IBM基于硬件的复制解决方案集成，确保HA/DR解决方案有助于最大化数据访问和可用性，以实现工作负载平衡和数据分发.
通过Assure HA/DR解决方案, you can extend 和 enhance the replication protection provided by IBM PowerHA SystemMirror for i. 确保HA/DR解决方案能够复制PowerHA无法复制的所有SYSBAS中的关键数据和应用程序. By replicating SYSBAS data concurrently with Power HA’s IASP data mirroring, 您可以确保恢复服务器始终拥有在故障转移时运行业务所需的所有数据的完整当前副本. The result is more complete protection 和 shorter recovery times.
And if 你的业务 relies on IBM Db2的镜子 for i, you know that it only supports replication between co-located, 现场数据库节点, exposing 你的业务 to serious unplanned downtime in the event of power or telecoms outages or, 更糟的是, potential data loss if the site is damaged or destroyed in a disaster.
通过将关键Db2数据复制到非站点或云托管恢复服务器，确保HA/DR解决方案为所有关键Db2数据提供真正和完整的容灾保护, for worry-free 计划内或计划外 failover. 它们还将数据实时复制到其他远程或本地非ha服务器，以用于分析和报告，从而帮助您从Db2数据中获得更多价值, without impacting your production systems.
迁移是不可避免的. 最终, 您将不得不升级或替换过时的技术，或更换性能更高的服务器，以管理更大的业务量. 其他时间, 您可以确定合并服务器或采用虚拟化技术是经济的. And those are just a few of the many reasons for server migrations.
传统上, migrations have meant extensive downtime, long hours of overtime on weekends 和 holidays, 和 significant business risk if any step of the process gets delayed or fails outright. 事实上, 在最近的精确调查中, as many as 42% of professionals reported having experienced a migration failure. Consequently, migrations often had to be redone, increasing the cost 和 downtime involved.
Assure HA/DR solutions streamline 和 simplify migrations, 消除了高压, 高风险, all-or-nothing experience 和 replacing it with confident, 控制, 和 professional execution that does not impact ongoing operations.
高效的实时复制允许您在后台透明地构建和加载新系统, 不让生产下线. 然后，它将使您的新系统与当前的生产保持同步，同时适当的注意和时间用于测试和调整, 确保一切都是完美的. 您可以并行地运行新环境，并完全与当前操作同步运行，以确保在上线之前完全就绪.
精确地提供经济的“桥梁许可”来支持您的迁移项目，并可以提供专业的服务和专家来补充您的团队在计划和执行期间. We can even h和le the entire project for you, ensuring the lowest possible impacts to your operations.

APL is a global business that operates 24×7 every day of the year. Consequently, the company tolerates no more than four hours of production system downtime per month. APL runs its core business applications on Power Systems servers, 非常可靠, 但单靠可靠性是不够的. Even the most reliable of systems requires periodic maintenance. In some cases, a single maintenance task can last longer than the acceptable monthly downtime.
APL需要一个能够保护其关键数据和应用程序并保持异常高可用性的环境, without putting an undue strain on business applications. Although its core applications were running on IBM i-based Power Systems, one of the most reliable platforms in the world, APL needed to do more to meet its dem和ing availability requirements. Even the most reliable systems need to be shut down for regular maintenance, 例如备份数据, reorganizing databases or upgrading the operating system. These necessary planned maintenance outages can be substantial. 例如, an operating system upgrade can shut a system down for 30 hours or more.

Underst和ing 和 Choosing HA/DR 解决方案
Every business today depends upon highly complex, internet-dependent IT 和 telecommunications systems. Making sure that data is protected against corruption or loss, 和 that systems are continuously available, 变得同样复杂. Given all the potential points of vulnerability present within 和 between your servers, 存储, 网络, 和互联网连接, 如何确保为您的公司选择了最好的高可用性和灾难恢复解决方案?
The most basic DR protection involves making frequent backups of all your data, 磁带或其他只读媒体. While this may have been enough 20 or 30 years ago, in today’s internet-dependent business world, backups alone are totally inadequate as a DR strategy. 与此形成鲜明对比的是, the ultimate solution is to maintain multiple highly redundant, geographically dispersed 和 highly secured systems 和 data stores which are continuously replicated, 经审计的, 和 synchronized to ensure continuous, 容错的可用性
In reality, neither of these extremes is appropriate or even feasible for most organizations. But between the two sits a wide variety of technologies offering various levels of data protection, 系统可用性, 恢复速度和完整性. 然而，仅仅按照从低端灾难恢复到高端高可用性的顺序列出这些解决方案是有误导性的. This is because HA 和 DR are not completely discrete or mutually exclusive requirements. Both may be required to provide complete protection.
例如, 基于磁带备份的容灾解决方案不能作为在短暂停机期间保持系统可用的手段, such as those required by normal maintenance. 同时, an HA solution is of no help in recovering from a wide-area disaster such as an earthquake, if the primary production 和 off-site HA backup systems are both impacted, which is quite possible if they are hosted in the same city. 即使它们是不同的, 地理上遥远的城市, if those cities are served by the same regional electric utility, a hurricane or major winter storm can bring down the entire regional grid, 和它, 你的业务.
底线是为了实现最好的HA和DR解决方案，以满足您公司的需求和预算, it is important to underst和 each technology option’s capabilities 和 limits in general, 和 to then evaluate the specific solutions being offered 和 the company that are behind them.
