        作为90年代和2000年代的拳击迷，我看着那个时代最著名的拳击手从自然而然的新手到戒指的统治者。尽管他们的才华和辛勤工作在职业生涯的早期推动了他们，但他们从未对自己的当前技能和调理感到满意。他们继续努力改善手动，移动，调节和力量，在多年以来，作为各自体重阶级的拥护者。

        现在您可能会问自己，拳击与复制或Nutanix有什么关系？Well, Nutanix, like the boxing legends we all know, continues to hone and improve our products with new capabilities, better performance, easier to navigate UI’s, etc. We don't have a “good enough” mindset where once we deliver a capability, we move onto the next. We continue to iterate and improve on it.

        为此，Nutanix提供了一种更有效的方法，将数据从一个Nutanix AOS™群集复制到另一个AOS群集以进行灾难恢复。新方法称为“基于范围的复制”或RBR。

        Nutanix长期以来将本机异步复制作为其核心产品的一部分。AOS 6.0之前使用的复制称为“基于范围的复制”或EBR，本质上非常颗粒状。简而言之，Nutanix混合多云平台以尺寸为1MB的粒度重复。但是，如果我们能做得更好并仅复制新编写或更改的确切数据怎么办？好吧，这正是我们所做的。AOS 6.0的新手，基于范围的复制将取代基于范围的复制，使客户更快地完成快照复制，并进一步帮助他们实现RPO并在停电时减少停机时间。为什么您可能会问这个重要？

        简而言之，RBR将帮助我们的客户不仅可以节省消耗的复制带宽，而且更重要的是降低其风险，从而使他们从灾难或中断中恢复了较少的数据丢失（RPO），同时花费更少的时间恢复（RTO）。

        为了证明新的RBR的有效性，我们决定使用最新的LTS版本，5.20在我们最新的STS版本，6.0中使用OLTP工作负载在快照复制测试中，旨在模拟我们的客户最常见的情况。事不宜迟，让我们来到磁带的故事。

        测试环境配置

        我们使用以下Nutanix硬件和软件来完成测试：

        • 一个四节点源群集和一个四节点目标群集
        • Nutanix AOS版本：5.20和AOS 6.0
        • 使用OLTP工作负载的模拟数据库
        • 每个节点都有1个VM，具有6个VDisk（4个数据磁盘和2个日志磁盘）
        • 每个VDISK为64GB
        • 数据磁盘充满了64GB的数据，日志磁盘中充满了4GB数据。
        • 对于整个群集，每个节点的总WSS为264GB和1056GB。
        • 显示基本快照加8个

        数据变更速率

        使用多个变更速率以及多个快照将表明RBR的增强对于低变化率有效，并且对更高变化率和较大快照计数的快照计数有效。该测试是在快照之间以多个变化率进行的：

        • 11％变化率：每个数据磁盘125 IO/s，每个日志磁盘12个IO/s（每个节点524 IO/s）
        • 22％变化率：每个数据磁盘250 IO/s，每个日志磁盘25 IO/s（每个节点1050 IO/s）
        • 38％变化率：每个数据磁盘500 IO/s和每个日志磁盘50 IO/s（每个节点2100 IO/s）
        • 62％的变化率：每个数据磁盘1000 IO/s和每个日志磁盘100 IO/s（每个节点4200 IO/s）

        

        

        

        

        结论

        Nutanix AOS 6.0基于基于范围的复制显示复制性能的提高约为60％，仅通过复制自上次快照以来已更改的确切数据。这使客户可以在更少的时间内复制更多数据，从而帮助将其纳入SLA的业务，从而降低风险。

        As a boxing fan in the 90\u2019s and 2000\u2019s, I watched the most famous boxers of the era rise from naturally-talented newcomers to dominators in the ring. And while their talent and hard work propelled them early in their careers, they were never satisfied with their current skills and conditioning. They continued to work hard on improving hand speed, movement, conditioning, and power en route to many years as champions of their respective weight classes. <\/span><\/p>

        Now you may be asking yourself, what does boxing have to do with replication or Nutanix? Well, Nutanix, like the boxing legends we all know, continues to hone and improve our products with new capabilities, better performance, easier to navigate UI\u2019s, etc. We don't have a \u201cgood enough\u201d mindset where once we deliver a capability, we move onto the next. We continue to iterate and improve on it.<\/span><\/p>

        To that end, Nutanix has delivered a more efficient method of replicating data from one\u00a0 Nutanix AOS\u2122 cluster to another AOS cluster for the purpose of disaster recovery. The new method is called\u00a0 \u201crange-based replication\u201d or RBR.\u00a0 <\/span><\/p>

        Nutanix has included native asynchronous replication as a part of its core offering for a long time. The replication used prior to AOS 6.0 is known as \u201cextent-based replication\u201d or EBR and is very granular in nature. Simply put, the Nutanix hybrid multicloud platform replicates at the granularity of an extent which is 1MB in size. But what if we could do better and replicate only the exact data that was newly written or changed? Well, that is exactly what we have done. New to AOS 6.0, range-based replication will replace extent-based replication, giving customers faster completion of snapshot replication, and further helping them achieve their RPO and lessen downtime in the event of an outage. Why is this important you may ask?<\/span><\/p>

        Simply put, RBR will help our customers not only save on the replication bandwidth consumed, but more importantly reduce their risk allowing them to recover from a disaster or outage with less data loss (RPO) while taking less time to recover (RTO). <\/span><\/p>

        To demonstrate how effective the new RBR is we have decided to put our latest LTS release, 5.20 up against our latest STS release, 6.0 in snapshot replication tests using an OLTP workload designed to simulate our customers' most common scenarios. Without further ado, let's get to the tale of the tape. <\/span><\/p>

        Test Environment Configuration<\/h3>

        We used the following Nutanix hardware and software to complete the testing:<\/p>

        • One four-node source cluster and one four-node target cluster<\/li>\t
        • Nutanix AOS version: 5.20 and AOS 6.0<\/li>\t
        • Simulated database with OLTP workload<\/li>\t
        • Each node has 1 VM with 6 vDisks (4 data disks and 2 log disks)<\/li>\t
        • Each vDisk is 64GB<\/li>\t
        • Data disks are filled with 64GB of Data and log disks are filled with 4GB of data.<\/li>\t
        • Total WSS per node is 264GB and 1056GB for the entire cluster.<\/li>\t
        • Showing Base snapshot plus 8 more<\/li><\/ul>

          Data Change Rate<\/h3>

          Using multiple change rates as well as multiple snapshots will show that the enhancements in RBR are effective for low change rates and a small snapshot count to higher change rates and larger snapshot counts. This test is conducted with multiple change rates in between the snapshots:<\/p>

          • 11% change rate: 125 IO\/s per data disk and 12 IO\/s per log disk (524 IO\/s per node)<\/li>\t
          • 22% change rate: 250 IO\/s per data disk and 25 IO\/s per log disk (1050 IO\/s per node)<\/li>\t
          • 38% change rate: 500 IO\/s per data disk and 50 IO\/s per log disk (2100 IO\/s per node)<\/li>\t
          • 62% change rate: 1000 IO\/s per data disk and 100 IO\/s per log disk (4200 IO\/s per node)<\/li><\/ul>
