AOS入门功能

徽章 +1

你好，

我希望对AOS启动器中包含哪些功能进行一些澄清。我通常使用以下链接作为指南：

Nutanix软件版和许可：在我们的电器上运行的解决方案

上面的链接指出，“基本压缩（LZ4） - 内联和后过程”包括起动器。但是，一旦我启用帖子压缩，我就会收到违反许可证的通知。在Prism元素中，它还显示了起动器和邮政压缩的可用功能为是：

启动器中有邮政压缩吗？

链接还指出，LZ4HC压缩不可用于起动器，但在入门簇上运行以下命令显示它可用并压缩数据：

curator_cli display_data_reduction_report

是否有过一些更改以使LZ4HC可用于首发？

是否有其他文档或链接包含每个版本可用的功能列表？

谢谢，

Hey\u00a0@zip<\/user-mention>\u00a0yes, that is absolutely correct, i.e if the delay is set to zero there will be NO post-process compression and it will be INLINE<\/strong> compression.<\/p>

\u00a0<\/p>

Exactly, with INLINE\u00a0compression, there will be no LZ4HC compression too.<\/p>

\u00a0<\/p>

Both your\u00a0points are correct.\u00a0\":smile:\"<\/p>

Hello,<\/p>

I was hoping to get some clarification as to what features are included in AOS Starter.\u00a0 I usually use the following link as a guide:<\/p>

Nutanix Software Editions & Licensing: Solutions to Run on Our Appliances<\/a><\/p>

The above link states that \u201cBasic Compression (LZ4) - Inline and post process\u201d are included starter.\u00a0 However as soon as I enable post compression I get a license violation notice.\u00a0 In prism element it also shows the available features for starter and post compressions shows as yes:<\/p>

\"//www.jhbzcj.com/next/how-it-works-22/\"<\/figure>

Is post compression available in Starter?<\/p>

\u00a0<\/p>

Also the link states that lz4hc compression is not available for Starter but running the following command on a starter clusters show it is available and compressing data:<\/p>

curator_cli display_data_reduction_report<\/p>

\u00a0<\/p>

Has something changed to make lz4hc available to starter?<\/p>

\u00a0<\/p>

Is there another document or link with a comprehensive list of features available for each edition?<\/p>

\u00a0<\/p>

Thanks,<\/p>

嘿 @压缩，这是正确的基本压缩（LZ4） - 在入门许可证。

而我很确定深度压缩（LZ4HC） - 冷数据的效率更高不支持入门许可证。

我认为违反许可证问题必须是GUI问题，否则错误将必须与许可团队联系。

但//www.jhbzcj.com/products/software-options是可用于许可信息的最佳文档。

hey @zip<\/user-mention>\u00a0, that is correct\u00a0Basic Compression (LZ4) - Inline and post-process are supported in Starter license.<\/strong><\/p>

\u00a0<\/p>

Whereas I am pretty sure that\u00a0Deep Compression (LZ4HC) - Greater efficiency for cold data<\/strong> is not supported for a Starter\u00a0license.<\/p>

\u00a0<\/p>

I think the license violation issue must be a GUI issue or a bug will have to check with the Licensing team.<\/p>

\u00a0<\/p>

But\u00a0\/\/www.jhbzcj.com\/products\/software-options<\/a>\u00a0is the best documentation available for the licensing information.\u00a0<\/p>

嘿，阿尼什，

感谢您的回复。我有两个后续问题：

  1. 说您只能具有内联压缩或后过程压缩是正确的，但是您不能同时启用两者。
  1. 由于深度压缩（LZ4HC）在冷数据上工作，因此我认为它是使用后处理压缩完成的。可以肯定地假设内联压缩不使用“深度压缩（LZ4HC）？
Hey Anish,<\/p>

Thanks for the response. I have two follow up questions:<\/p>

  1. Is it correct to say that you can only have inline compression\u00a0or post process compression but you cannot have both enabled a the same time.\u00a0\u00a0<\/li><\/ol>
    \"//www.jhbzcj.com/next/how-it-works-22/\"<\/figure>
    1. Since Deep Compression(LZ4HC) works on cold data I assume it is done using post-process compression.\u00a0 Is it safe to assume that inline-compression does not use \u201cDeep Compression(LZ4HC)?<\/li><\/ol>","quoteUsername":"zip","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嘿 @压缩，您的这两个观点都是正确的。：微笑：

内联压缩- 数据在编写之前被压缩。

后处理压缩- 一旦数据冷却后，它就有资格被压缩，即在通过压缩延迟后。所有新写入I/O均以未压缩状态编写。在满足压缩延迟（可配置）之后，在这种情况下，数据有资格被压缩。

这是一个很棒的视频，突出了两者之间的区别：

正常数据将使用LZ4压缩在压缩和性能之间提供了很好的融合。对于冷数据，将利用LZ4HC提供改进的压缩比。

Nutanix圣经以非常详细且易于理解的方式解释：https://nutanixbible.com/#anchor-book-of-aos-compression

希望它能帮助交配。：微笑：让我知道我是否可以以其他方式提供帮助。

阿尼什·辛格·瓦利亚（Anish Singh Walia）
Hey @zip<\/user-mention>\u00a0, Both of your points are correct.\u00a0\":smile:\"<\/p>

Inline compression<\/strong> - Data is compressed before it is written.<\/p>

Post-process Compression<\/strong>-\u00a0\u00a0Once the data cools down it is then eligible to become compressed i.e after it passes the compression delay.\u00a0\u00a0All new write I\/O are\u00a0written in an uncompressed state.\u00a0 After the compression delay (configurable) is met, the data is eligible to become compressed in this scenario.<\/p>

\u00a0<\/p>

This is a great video which highlights the difference between both:\u00a0<\/p><\/oembed>

\u00a0<\/p>

Normal data will be compressed using LZ4<\/strong> which provides a very good blend between compression and performance. For cold data, LZ4HC will be leveraged to provide an improved compression ratio.<\/strong><\/p>

\u00a0<\/p>

Nutanix Bible explains it in a very detailed and understandable manner:\u00a0<\/strong>https:\/\/nutanixbible.com\/#anchor-book-of-aos-compression<\/a><\/p>

嘿，阿尼什，

在这里发布之前，我观看了该视频，还阅读了该链接，但仍然不确定。

多亏了Nutanix的出色文档，我了解了内联压缩和后压缩工作。我也知道LZ4HC在冷数据上工作。

如果我的压缩延迟设置为零，如这张图片所示：

我的问题是：假设如果将延迟设置为零，则不会有后处理压缩是正确的吗？另外，由于LZ4HC是压缩后过程，我认为也没有LZ4HC压缩。

谢谢，

- 压缩

Hey Anish,<\/p>

\u00a0<\/p>

Prior to posting here I watched that video and also read that link but was still uncertain.<\/p>

\u00a0<\/p>

Thanks to Nutanix\u2019s excellent documentation I understand how inline compression and post compression work.\u00a0 I also understand that LZ4HC works on cold data.\u00a0<\/p>

\u00a0<\/p>

If I have Compression delay set to zero as seen in this picture:<\/p>

\u00a0<\/p>

\"//www.jhbzcj.com/next/how-it-works-22/\"<\/figure>

\u00a0<\/p>

\u00a0<\/p>

My question is: Is it correct to assume if delay is set to zero there will be NO post-process compression.\u00a0 In addition since LZ4HC is a post-compression process I assume there will be no LZ4HC compression either.<\/p>

Thanks,<\/p>

嘿 @压缩是的，这是绝对正确的，即如果将延迟设置为零，则不会有后处理压缩，它将是排队压缩。

确切地说，通过内联压缩，也不会有LZ4HC压缩。

您的观点都是正确的。：微笑：
