大家好你们好，

我刚刚发现，可以从Nutanix群集节点中的960GB SSD中使用531,82GB。使用1,92TB SSD提供1.22TB的可用空间。

3,84TB SSD呢？这些驱动器可以使用多少空间？

谢谢

Hi everybody,<\/p>

I just found out that 531,82GB can be used from 960GB SSDs in a Nutanix cluster node. Using 1,92TB SSDs offer 1.22TB usable space.<\/p>

What about the 3,84TB SSDs. How much space can be used with these drives?<\/p>

Thanks<\/p>

嗨didi7

请给您更多的背景吗？你在哪里看到这个？群集RF2是吗？集群使用的功能是什么（例如，擦除编码）？您可以使用nutanix sizer。

Hi Didi7<\/p>

Could you give a little more context, please? Where did you see this? Is the cluster RF2? What are the features that the cluster is using (erasure coding, for example)? You can project the usable space using Nutanix Sizer.<\/a><\/p>","quoteUsername":"Alona","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨，Alona，

我们在所有Nutanix簇中使用RF2。我可以通过单击“ home” => hardware =>表=>磁盘（Prism元素）…

在那里，我可以看到，531.82 GIB可从960GB SSD中使用，在另一个集群中相同，在该集群中，我们有1.92 TB SSD（而不是960GB），并且可用大小为1.22TB。

现在，我想知道3.84TB SSD可用的空间，不同SSD的可使用空间的百分比很大。

Hi Alona,<\/p>

we use RF2 in all our Nutanix clusters. I can see those figures by clicking Home => Hardware => Table => Disk (Prism Element) \u2026<\/p>

There I can see, that 531.82 GiB are useable from a 960GB SSD, same in another cluster, where we have 1.92 TB SSDs (instead of 960GB) and there the usable size is 1.22TB.<\/p>

Now I would like to know how much space is available from a 3.84TB SSD, the percentage of ususable space from different SSDs differ a lot.<\/p>

嗨didi7，

SSD的可用空间将根据是否在磁盘上安装了CVM，是否是全闪存群集，混合动力和许多其他变量。大概您可以期望看到50％。在从TB/GB转换为TIB/GIB后的现实生活中，OPLOG计算和其余的可用空间略高于50％。

驱动器故障解释一些影响可用能力的原因。

Hi Didi7,<\/p>

Usable space for SSDs will vary depending on whether CVM is installed on the disk, if it\u2019s an all-flash cluster or a hybrid and many other variables. Roughly you can expect to see 50%. In real life after conversion from TB\/GB to TiB\/GiB, oplog calculations and the rest the usable space is a bit higher than 50%.\u00a0<\/p>

Drive Breakdown<\/a> explains some of what affects the usable capacity.<\/p>
