在VDI POC中写下延迟


徽章 +6
我们使用3节点Dell XC720XD群集在客户站点上执行POC。从vCenter获取的统计数据显示,在1 ms左右的平均读取率和5-6 ms的写入延迟。

写潜伏期似乎太高了,因为它应该仅在SSD上制作2个写作(基础和副本)。我想知道CVM是否有一个计时器,然后才将悬而未决的写入给OPLOG。

这可能有助于一般来说减少I/O的数量并增加对SSD有益的大小。

不幸的是,在我们的POC中,我们正在与Fusion-io PCI卡当前对服务器的配置作斗争,这种方法可能是不利的。

另一个重要参数是当前系统上平均35-40秒的登录时间,并使用Nutanix达到75秒。

加快Nutanix群集的任何建议可能正在修改一些参数吗?

您是否在同一广告中使用同一图像?棱镜中的“存储”选项卡上显示的延迟是什么?
徽章 +6
是的,

这是一个图像。桌面不持久,并分配给登录处的用户。他们在外部存储上使用漫游配置文件和文件夹重定向。用户配置文件的下载触发了大量在登录时间写入。如今,随着18-20个活动台式/节点的负载增加,平均写入延迟最高为7.5毫秒,平均读取延迟高达2.3 m。

更糟糕的是观察到峰值潜伏期。我们监视了一个“非常活跃”的特定虚拟桌面。它的写入/秒为40到80,写潜伏期最高为20毫秒以上。

我认为肯定有问题,因为总负载平均为240 IO/秒。但是,每个请求的峰值都会导致潜伏期激增。

最后一句话:最小写潜伏期永远不会低于6 ms。

我们没有从Prism的“存储”选项卡中的数据,因为我们可以获取数据,只要求客户为我们获取它们,而他不知道如何使用Prism。我们可以安排指示他获取数据表Prism。我们已经看到了Delta nd的大小低于4 GB,因此4x45用户是180GB,应该舒适地保持在SSD层。

客户的主要抱怨是登录时间是当前环境的两倍。由于每个VM平均执行6-8 IO/sec,因此6 ms平均写入潜伏期不应该是登录后的问题,但是我们已经看到了一定的请求峰值,这立即将延迟提高到20 ms。

当然,这些结果在POC中造成了一个问题。

我无法评论写潜伏期,但是我在Xendesktop POC和GPO和文件夹重定向方面遇到了同样的问题。我必须创建新的GPO并申请而不是使用现有的GPO,并且能够在10秒以下获得登录时间。

是的,不对劲,会打开支持票。我怀疑Flash层是否已满,因此此时可能是一个全闪存阵列。我会从问题中倒退。我会阻止AD中的Inhertieance,创建一个新用户,而不是使用Romaing Croiles,文件夹重定向。然后慢添加东西。

什么是全新的台式机,没有附加到域的外观。我知道,当使用最小的GPO时,我的登录时间低于4s。

您也可以运行NCC来verfiry。我还会确认DNS不会与您搞砸。

由于POC是基于戴尔电器,所以我昨天要求戴尔打开支持票。

在客户环境中可能会有很多改进,但这并不能解释应取决于存储的Nutanix实施的写入潜伏期。此外,读取可以在SSD上或HDD层上进行,但是在本环境中的所有写入都应该转到SSD层,该级别应具有1 ms左右的潜伏期...

嗨,史蒂夫,

您是否曾经找出在POC期间经历的Flash层上写潜伏期的来源?我很想知道该决议是什么。谢谢
