SSD的尺寸可在节点中达到高清DD的容量

只是关于在节点（在新的同质群集中）中尺寸SSD容量尺寸的HDD容量的快速问题。当在节点中指定驱动空间时，最小值的每个节点的SSD百分比是多少。有没有人可以指向我的最佳练习指南？我不是在询问HDD的数量与SSD的数量。

问题是围绕容量，而不是数字或驱动器。例如我配置了一个带有4TB的SSD（2x1.92tb）和60TB的HDD（10 x 6tb）的节点，而Nutanix Sizer表示这很好。这大约是6.25％的SSD，但是我应该拥有的混合节点的最低SSD容量可以6％，还是更像是10％或20％（或更多）？

Hi @tcourtney-72782<\/user-mention>\u00a0<\/p>

The problem there may possibly be with the performance of the cluster. It will greatly depend on what kind of workload you run there. If you want to run OLTP databases or any heavy IOPS workload with low latency expectations, it might be a good idea to size more SSD. If you plan to have a lot of cold data and latency is not that important, smaller SSD tier size will do. We generally recommend to never size the SSD tier below 10% of the total capacity, but overall the higher SSD ratio, the better performance you will get.<\/p>

You should also check your working set size and it should fit into the SSD tier. Check with the application owners how much new data\u00a0do their applications write per day. You can also check the incremental backup sizes. Incremental daily backups will have the data from the last day only, so it will provide some indication of how much new data is generated daily. Aim to make sure that the working set will fit into the 75% of the SSD tier and don\u2019t forget about the RF2\/RF3. And of course leave some free space for the future growth.<\/p>","className":"post__content__best_answer"}">

Just a quick question about sizing SSD capacity to HDD capacity in a\u00a0node (in a new homogenous cluster). When specifying drive space in a node, what is the percentage SSD to HDD per node at a minimum. Is there a best practice guide that someone can point me towards? I\u2019m not asking about the number of HDDs vs the number of SSDs.<\/p>

The question is around capacity and not number or drives. e.g.\u00a0I configure a node with 4TB of\u00a0SSD (2x1.92TB) and 60TB\u00a0of HDD (10 x 6TB) and Nutanix Sizer says this is fine. This is roughly 6.25% SSD But what should I have as a minimum SSD capacity of of a hybrid node is 6% Okay, or should it be more like\u00a010% or 20% (or more)?<\/p>","quoteUsername":"tcourtney-72782","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好 @tcourtney-72782

群集的性能可能存在问题。这将在很大程度上取决于您在那里运行哪种工作量。如果您想运行OLTP数据库或任何较重的IOPS工作负载，而延迟期望则低，那么大小SSD尺寸可能是个好主意。如果您打算拥有大量的冷数据和潜伏期并不重要，那么较小的SSD层尺寸将会有所作为。我们通常建议不要将SSD层缩小到总容量的10％以下，但总体而言，SSD比率越高，您将获得的性能越好。

您还应该检查工作组尺寸，并且应该适合SSD层。请与应用程序所有者核实每天写的新数据进行了多少新数据。您也可以检查增量备份大小。每日备份的增量只会从最后一天起拥有数据，因此它将提供一些每天生成多少新数据的指示。旨在确保工作组适合SSD层的75％，并且不要忘记RF2/RF3。当然，为未来的增长留下了一些自由空间。

嘿 @tcourtney-72782，，，，

如果您从Hyper-V或ESXI迁移的某种类型，请带Nutanix Collector检查您拥有多少个工作数据。这种尺寸加25％是您的SSD层尺寸。

作为 @Sergei Ivanov提到的10％是绝对的最低限度，我建议以20％的尺寸大小。

亲切的问候，

Serger

Hey @tcourtney-72782<\/user-mention>,<\/p>

if you some kind migrating from Hyper-V or ESXi, take nutanix collector to check how many working data you have. this size plus 25% is your SSD tier size.<\/p>

As @Sergei Ivanov<\/user-mention>\u00a0mentioned 10% is absolute minimum, i would recommend to size at 20%.<\/p>

\u00a0<\/p>

Kind regards,<\/p>
