嗨，Nutanix社区，
我们经常想知道Nutanix群集上可用的真实存储容量是什么。

我们在RF2中有一个三个节点簇。
在Prism Element主页中，在“存储摘要”下，我看到：20.87Tib Free（逻辑）22.37 TIB
https：//
数据弹性还可以。（绿色）

以下哪个陈述正确？
  • 我可以在不丢失数据弹性的情况下将存储空间填充到22.37 TIB（=我可能会丢失节点而不会丢失数据）。
  • 我只能填充22.37tib（= 14.76Tib）的存储空间，而不会丢失数据弹性
谢谢
\r\nWe often wonder what is the real storage capacity available on a Nutanix cluster.
\r\n
\r\nWe have a three node cluster, in RF2.
\r\nIn Prism Element main page, under \"Storage Summary\", I see : 20.87TiB free (logical) of 22.37 TiB
\r\nhttps:\/\/
\r\nData Resiliency is OK. (green)
\r\n
\r\nWhich one of the following statements is correct ?
\r\n
    \r\n
  • I can fill my storage up to 22.37 TiB without losing the data resiliency (=I can lose a node without losing data). \r\n
  • I can fill my storage only up to 66% of 22.37Tib (= 14.76Tib) without losing the data resiliency \r\n<\/ul>\r\nThank you 🙂","quoteUsername":"Infomil","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我们的经验是，您只能填充最多一部分广告的自由空间的存储空间（声明＃2）。至于确切百分比或如何计算它...我不确定。总存储所有节点-1吗？是否有需要考虑的开销？这就是引导我这里的原因，寻找这些答案。

薄vs厚的配置，物理与逻辑，实际数据，跑道...我仍在尝试找到有意义且准确的报告，这将有助于我们监视使用情况并提醒我们，然后才能达到临界点。

\r\nThin vs thick provisioning, physical vs logical, actual data used, runway ... I'm still trying to find meaningful and accurate reports that will help us monitor usage and alert us before we hit that tipping point.","quoteUsername":"tromo","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我们已经测试过。
结论在我的情况下是：当我低于免费存储的36.5％以下时，数据弹性状态从确定到关键。
带有以下警告：
“群集无法忍受节点故障并保证可用的重建能力”
“带有节点的元数据环分区：CVMIP1，CVMIP2，CVMIP3不容忍。”
\r\nThe conclusion, in my scenario is: when I go below 36.5% of free storage, the Data Resiliency Status goes from OK to Critical.
\r\nWith the following warnings:
\r\n\"Cluster can not tolerate node failure and guarantee available rebuild capacity\"
\r\n\"Metadata ring partitions with nodes: cvmIP1, cvmIP2, cvmIP3 are not fault tolerant.\"","quoteUsername":"Infomil","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

大家好，

在过去的四个月中，我与不同的客户经历了两个类似的案例，他们用来了太多的可用存储，导致其群集表现出至关重要的数据弹性状态。

请查看以下KB文章，介绍有关Nutanix群集最大存储利用的推荐准则：https://portal.nutanix.com/#/page/kbs/details?targetId=ka0600000008duccaa。

这篇文章为我提供了所需的公式来计算存储利用的确切阈值，超过该阈值不再是数据弹性。

我希望这也对您有所帮助。

此致，

\nIn the last 4 months, I experienced two similar cases with different customers who used up too much of their available storage causing their cluster to show Critical status for Data Resiliency.
\n
\nPlease check out the following KB article regarding the recommended guidelines for maximum storage utilization on a Nutanix cluster: https:\/\/portal.nutanix.com\/#\/page\/kbs\/details?targetId=kA0600000008ducCAA<\/a>.
\n
\nThat article provided me with the required formula to calculate the exact threshold on storage utilization beyond which a Nutanix cluster becomes Not Data Resilient anymore.
\n
\nI hope this helps you out as well.

各位，

首先，感谢您打开此主题。

我s there an option or setting to tell the storage summary diagram that please draw a line like: ‘Dear Operator, with the current storage settings you can utilize your cluster till XY TB/GB/whatever?’ I think many Nutanix Cluster will be operated by engineers and technicians with different level of Nutanix knowledge and I have a fear that not everybody can take care of this.

谢谢，

你好，

我听说它将包含在以后的版本中。一门课程中的一名教练告诉我。不幸的是，没有KB文章或类似文章。

Hi,<\/p>

\u00a0<\/p>

I have heard that it will be included in a future version. I was told this by a trainer in a course. Have unfortunately no KB article or similar.<\/p>

嗨，信息，

可用的逻辑空间考虑了在群集上配置的复制因子（RF2或RF3），该群集定义了要存储的数据副本的数量。对于RF2，这将是两个副本，对于RF3，三个数据副本。

在20.87Tib的群集级别上，免费（逻辑）22.37 tib，您可以使用20.87tib。不建议超过85-90％的利用率。

对于存储容器，请注意，如果未启用空间预订（不能保证容器的空间），则如果存储池的自由空间较小，则容器的空间相同，则容器上的可用空间将等于免费存储池的空间。与同一池上多个存储容器一起工作时要记住的事情。

Hi Infomil,<\/p>

The logical space available takes into account the replication factor (RF2 or RF3) that is configured on the cluster which defines the number of copies of the data to be stored. For RF2 that would be two copies and for RF3 three copies of data.<\/p>

On a cluster level for 20.87TiB free (logical) out of 22.37 TiB you can use 20.87TiB. It is not recommended to go above 85-90% utilisation.<\/p>

For a storage container note that if space reservation is not enabled (space is not guaranteed for the container) then if the free space of the storage pool is less then the same of the container, free space on the container will be equal to the free space of the storage pool. Something to keep in mind when working with multiple storage containers on the same pool.<\/p>","quoteUsername":"Alona","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
