大家好，

我想知道人们在异步保护域上具有哪些配置？

每pd多少VM
通过应用程序/部门/角色创建许多PD和组
- 一个组中的所有Web服务器，所有SQL服务器，所有应用程序服务器
- 所有基于人力资源的系统，所有基于IT的系统，所有基于未婚夫的系统
在集群中可以拥有多少个PD有限吗
在许多较小的PD上拥有更少的大PD的差异/优势是什么
本地/远程快照是什么频率和保留率
激活PD时出现什么问题
我相信IP地址将被删除，Mac将会更改...正确？，是否应用了任何脚本或自动化？

感谢您可以给出的任何回复。

问候

戴夫

\nI'm wondering what configurations people have on Async Protection Domains?

\n

\n

How many VMs per PD
\n
Create many PDs and group by application\/department\/roles eg
- All Web servers in one group, all SQL servers, all application servers \n
- All HR based systems, All IT based systems, All Fiance based systems<\/ul> \n
- Is there a limit on how many PDs you can have in a cluster \n
- What's the dis\/advantage to having fewer large PDs over many smaller PDs \n
- What frequency and retention are the local\/remote snapshots \n
- What issues arrise when activating a PD \n
- I believe the IP address will be removed and the MAC will change...correct??, any scripts or automation applied?<\/ul>
  
  \nThanks for any response you can give.

作为一般性声明，如果您还没有，请在Nutanix圣经中查看此部分：http://nutanixbible.com/#anchor-backup-and-disaster-recovery-79

这是您从我的POV进入的问题的答案

每pd多少VM
- - 以前的版本的限制为50 VM/pd，但最高为200 VM/PD。
通过应用程序/部门/角色创建许多PD和组
- 一个组中的所有Web服务器，所有SQL服务器，所有应用程序服务器
- 所有基于人力资源的系统，所有基于IT的系统，所有基于未婚夫的系统
- - 通常，我们建议人们将PD映射到应用程序堆栈，因此应用程序堆栈中的所有内容都得到了相同的处理。经典示例是SharePoint之类的，它具有Web前端层，App Server Tier和DB/Blob后端。将所有这些项目放入单个PD中，并将其称为“ SharePoint01”或类似的东西
在集群中可以拥有多少个PD有限吗
- 并不是我看过
在许多较小的PD上拥有更少的大PD的差异/优势是什么
- - 缺点 - 大型PD的调度粒度不那么灵活
- - 优势 - 大型PD的配置较少，从概念上讲，这更容易管理
- - 一般评论 - 如果您将PD与应用程序保持一致，您会发现您自然会有更多的PD，并且它们会相对自我记录，从DR的角度来看，这很有帮助。
本地/远程快照是什么频率和保留率
- - 我几乎看到了您想像的一切，从短，更活跃的快照到一周的不同日子，每周一次，等等。无论哪种方式，都应该直接链接到您的业务需求以及您的应用程序需要什么样的RPO，而不仅仅是拿走数十亿个快照并永远保持它们（前提是您有HTAT的空间）
激活PD时出现什么问题
- - 总的来说，我会坦率的，最大的挑战是恢复顺序（服务器首先出现，等）和网络/IP地址。作为未来版本的一部分，我们正在增强产品来照顾这些产品，但是这些是我们从2美分中获得最多的反馈。
我相信IP地址将被删除，Mac将会更改...正确？，是否应用了任何脚本或自动化？
- - 如果您不在双方使用AHV，那么是的，我们还没有IP地址编排（编排即将到来）。如果您使用的是AHV，则可以将网络A映射到网络B，并且IP地址将自动处理。也就是说，这里有少数脚本会在这里提供帮助，功能会有所不同，但是如果您是Saavy Spripter，则应该能够制作培根。

\nAs a general statement, if you haven't already, check out this section in the Nutanix bible: http:\/\/nutanixbible.com\/#anchor-backup-and-disaster-recovery-79<\/a>

\n

\nHere's answers to your questions from my POV in-line

\n

\n

How many VMs per PD
- Create many PDs and group by application\/department\/roles eg
  - Is there a limit on how many PDs you can have in a cluster
    - What's the dis\/advantage to having fewer large PDs over many smaller PDs
      - What frequency and retention are the local\/remote snapshots
        \n
        \ufeff - I've seen just about everything you'd imagine from short, more active snaps, to different days of the week, to once per week, and so on. EITHER WAY, this is should be directly linked to your business requirements and what sort of RPO's your applications need, rather than just taking a zillion snapshots and keeping them forever (providing you have space for htat)<\/ul> \n
        What issues arrise when activating a PD
        \n
        \ufeff - In general, I'll be candid, the largest challenges are recovery ordering (which servers come up first, etc) and network\/IP addressing. We're enhancing the product to take care of these as part of future releases, but those are the areas we get the most feedback in from my 2 cents.<\/ul> \n
        I believe the IP address will be removed and the MAC will change...correct??, any scripts or automation applied?
        \n
        \ufeff - If you are NOT using AHV on both sides, then yes, we do not yet have IP address orchestration (that orchestration is coming). If you ARE using AHV, you can map Network A to Network B, and IP addresses will be handled automatically. That said, there are a handful of scripts out there that will help out here, functionality varies, but if you're a saavy scripter, you should be able to make the bacon. \n

嗨，谢谢您的详细回复。

我的想法是通过应用程序/解决方案将VMS（或实体使用Nutanix术语）组为CGS，然后根据快照时间表在PD中。

我们的DB备份每小时对关键系统进行交易日志，因此实际上是我们保护的操作系统和应用程序。

我们在两个群集上运行ESX/AHV，我确实考虑过在DHCP中保留IP，但我知道这可能会导致其他问题。

您链接到的脚本很复杂，而不是我想投入生产环境的内容，因此他们必须等待我们的测试群构建，我将进行测试。同时，我现在必须暂时求助于旧学校批次脚本。

再次感谢您的回复乔恩。

问候

戴夫

\nMy thoughts were to group VMs (or entities to use the Nutanix terminology) by application\/solution into CGs then in a PD based on snapshot schedule.

\n

\nOur DB backups take transaction logs every hour for critical system so it's really the OS and applications we're protecting.

\n

\nWe are running ESX\/AHV over the two clusters and I did think about reserving the IP in DHCP but I know that could cause other issues.

\n

\nThe scripts you have linked to are complicated and not something I would want to throw into a production environment, so they'll have to wait for our test cluster to be built and I'll be testing them. In the mean time I'll have to resort to old school batch scripting for now.

\n

\nThanks again for your response Jon.

我可以从10 VM的较大保护组中故障转移一个VM/实体，或者整个PG都必须使用所有VM进行故障转移？
