This week on the podcast, Dwayne chats with Marc Trouard-Riolle, about Nutanix Cloud Clusters (NC2) on Azure and how to get started. Nutanix Cloud Clusters (NC2) on Microsoft Azure enables your applications to be run where you want them, on-premises or in the public cloud, all operated as a single cloud.<\/p>

同步复制要求

C

大家好。

我正在计划具有AHV的两个站点之间的同步复制，并且文档中尚不清楚先决条件。我的主机上有960GB SSD磁盘。显然，所需的最低限度为1.2TB，但在文档中没有明确。有人知道我可以在哪里验证这些信息吗？

谢谢！:)

Hello everyone.<\/p>

I am planning synchronous replication between two sites with AHV, and the prerequisites are not clear in the documentation. I have 960GB SSD disks on the hosts. Apparently the minimum required is 1.2TB but it's not explicit in the documentation. Does anyone know where I can validate this information?<\/p>

\u00a0<\/p>

Thanks! :)<\/p>","quoteUsername":"Clemilton","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

对于具有异步，近乎同步和同步复制时间表的DR Solutions成功，因此本地AZS（AZS或AZS）中的节点必须具有某些资源。本节提供有关支持基于RPO的恢复点频率所需的节点，磁盘和基础配置的信息。

  • 本节中提供的条件和配置适用于本地和远程恢复点。

  • 任何具有两个或多个SSD的节点配置，每个SSD为1.2 TB或更高的容量，都支持靠近索尼克的恢复点频率。

  • 任何支持六（6）小时恢复点频率的节点配置也支持基于AHV的同步复制时间表，因为具有同步复制时间表的保护策略每6小时都需要受保护的VM的恢复点。

For DR solutions with Asynchronous, NearSync, and Synchronous replication schedules to succeed, the nodes in the on-prem AZs (AZs or AZs) must have certain resources. This section provides information about the node, disk and Foundation configurations necessary to support the RPO-based recovery point frequencies.<\/span><\/p>
  • \t

    The conditions and configurations provided in this section apply to Local and Remote recovery points.<\/p>\t<\/li>\t

  • \t

    Any node configuration with two or more SSDs, each SSD being 1.2 TB or greater capacity, supports recovery point frequency for NearSync.<\/p>\t<\/li>\t

  • \t

    Any node configuration that supports recovery point frequency of six (6) hours also supports AHV-based Synchronous replication schedules because a protection policy with Synchronous replication schedule takes recovery points of the protected VMs every 6 hours.<\/p>\t<\/li><\/ul>

Nutanix AHV支持2个选项：

  • 近同步
    • 对于近同步至少1.2TB SSD。
    • RPO您的15分钟以下
  • 同步代表（地铁）
    • 实时复制（零RPO）
    • 每个站点都有自己的Nutanix群集，但是在确认写入之前，通过同步复制到远程站点来“拉伸”容器。
    • 基本上，您应该有足够的SSD免费用于同步REP数据。

请Nutanix DR文档以获取详细信息

Qamar
Nutanix AHV Support 2 options:<\/p>
  • Near-Sync\t
    • for Near-Sync atleast 1.2TB SSD is required.\u00a0<\/li>\t\t
    • RPO you get below 15Mins\u00a0<\/li>\t<\/ul><\/li>\t
    • Sync Rep (Metro)\t
      • Real Time Replication (\u00a0Zero RPO)<\/li>\t\t
      • each site has its own Nutanix cluster, however the containers are \u201cstretched\u201d by synchronously replicating to the remote site before acknowledging writes.<\/li>\t\t
      • Basically you should have enough SSD free for Sync Rep data.<\/li>\t<\/ul><\/li><\/ul>

        Please Nutanix DR Documentation for details<\/p>","quoteUsername":"qamarabbas","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
