Sizer范围存储和实际容器尺寸

有人可以确认Nutanix Sizer工具中显示的范围是否等于VM可以用于数据存储的容器最大容量？

我正在设计一个带有以下磁盘的3节点群集
3 * 960 GB SSD
6 * 4 TB HDD

Nutanix Sizer显示范围存储（假设RF2）= HDD的9.63 TI​​B，SSD的tib为0.64 TIB
显示的总数为10.27。该值是否是由存储库制成的容器可用的最大容量？

正如我观察到的，容器的最大容量正好是存储池容量所显示的一半。上述规格显示的存储池容量将是什么？在nutanix sizer工具/存储容量计算器中可见该值是什么？

\r\nThe (max) storage container capacity is SIZE of Storage Pool divided by RF.
\r\nAnd yes<\/b>: the output for effective capacity (RFx) is the container max. capacity.
\r\nPlease also take into consideration the failover capacity<\/u>: if you have more than 6,9 TB used it cannot tolerate a node failure anymore.
\r\nAlso please note that there may be some small differences<\/u> between the sizer output and your planned cluster environment.","className":"post__content__best_answer"}">

    \r\nI am designing a 3-node cluster with following Disks
    \r\n3 * 960 GB SSD
    \r\n6 * 4 TB HDD
    \r\n
    \r\nNutanix Sizer shows Extent Store (Assuming RF2) = 9.63 TiB for HDD and 0.64 TiB for SSD
    \r\nThe total shown is 10.27. Will this value be the Maximum Capacity available for the Container to be made out of storage pool?
    \r\n
    \r\nAs I have observed the Container Maximum Capacity is exactly half of what the Storage Pool Capacity is shown. What will be the Storage Pool Capacity shown for the above mentioned specs and is this value visible in Nutanix Sizer tool\/Storage Capacity Calculator?","quoteUsername":"Muhammad Usman Ayub","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    嗨，穆罕默德，

    （最大）存储容器容量是存储池的大小除以RF。
    和是的：有效容量的输出（RFX）是容器最大。容量。
    请考虑F能力：如果您使用了超过6,9 TB，则无法忍受节点故障。
    另请注意，可能有一些小差异在Sizer输出与计划的集群环境之间。

    ...也请考虑F能力：如果您使用了超过6,9 TB，则无法忍受节点故障。

    你好曼弗雷德，

    关于这一点，我的理解是，群集将无法重建两个剩下的节点中所有数据的RF2策略（因为它们已经满了），因此，如果第三个节点没有返回在线，则群集将保持降级（但是所有数据仍然可用，其中一些只有一个副本）。这种解释正确还是群集丢失数据？

    \r\nHello Manfred,
    \r\n
    \r\nAbout this, my understanding is that the cluster will not be able to reconstruct the RF2 policy for all data in the two remaining nodes (because they're already full), so if the 3rd node doesn't come back online, the cluster will remain degraded (but with all data still available, just some of it will only have a single copy). Is this interpretation correct or does the cluster lose data?","quoteUsername":"eccnet","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    即使您有2个节点，nutanix也会尝试在拥有足够的容量时重建数据。
