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导:

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后压缩的可用功能,显示为是:

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>

\u00a0<\/p>

I hope I cleared your doubts. Let me know if I can help in any other way.<\/p>","className":"post__content__best_answer"}">

@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。

嘿阿尼什,

感谢您的回复。我有两个后续问题:

  1. 可以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)?

@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,即通过压缩延迟。所有新的写入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压缩这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。

嘿阿尼什,

在此处发布之前,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。另外,由于LZ4HC是一个压缩过程,因此我认为也没有LZ4HC压缩。

谢谢,

@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排队压缩。

确切地说,通过内联压缩,也不会有LZ4HC压缩。

你的观点都是正确的。:微笑:

希望我能解决您的疑问。让我知道我是否可以以其他方式提供帮助。
