实际上,我们的客户之一是拥有2个8系节点和1个6系节点的Nutanix群集。因为他们想要与当前可用的物理中的相同设置。一个硬盘在物理上并运行Jetstress测试。但是,在这样做时,测试失败了,当他们尝试将磁盘添加回其显示无效的磁盘配置时,测试和测试失败。

\nActually one of our customer is having a nutanix cluster of 2 8 series node and 1 6 series node.because they want the same setup like their physical infra available currently.The jetstress testing was going on fine with the customer .but they want to remove one hard disk physically and run the jetstress test.but on doing that the test got failed and when they tried to add the disk back its showing invalid disk configuration.and tests are failing.

几件事,您首先看到了有关在分层存储设备上测试的有关Jetstress测试的文章?
http://www.joshodgers.com/2016/01/26/jetstress-testing-with-intelligent-tiered-storage-platforms/
我建议您审查并在此处遵循建议。
第二:结帐本系列显示了Jetstress的性能测试,其中显示了Nutanix上Jetstress的VMotion(and Suon)场景测试视频。
http://www.joshodgers.com/2016/02/01/microsoft-exchange-20132016-jetstress-jetstress-performance-performance-testing-on-nutanix-on-nutanix-nutanix-acropolis-hypopolis-hypopolvisor-ahv/
第三:如果您遵循了我们的建议并具有n+1设置,这意味着比集群中的总节点要少1个交换服务器,那么您应该能够在Jetstress在该节点上运行时关闭CVM,并且测试应继续并通过与大约N-1的影响。例如:如果您在四个节点群集中获得2000 IOPS,则如果取出一个节点,则应看到1500。这就是我在这些故障情况下所拥有的pbs,群集越大,影响越低。重要的是,它是一种可预测且优雅的退化,而不是“脱离悬崖”风格的问题。
让我知道您的状态,我的目标是在接下来的几天内将其余的视频发布在交换性能测试系列中。
干杯
\nA few things, firstly have you seen this post regarding Jetstress testing on tiered storage devices?
\n
\nhttp:\/\/www.joshodgers.com\/2016\/01\/26\/jetstress-testing-with-intelligent-tiered-storage-platforms\/<\/a>
\n
\nI would recommend you review and follow the recommendations here.
\n
\nSecond: Checkout this series showing Jetstress performance testing which shows vMotion (and soon) failure scenario testing videos of Jetstress on Nutanix.
\n
\nhttp:\/\/www.joshodgers.com\/2016\/02\/01\/microsoft-exchange-20132016-jetstress-performance-testing-on-nutanix-acropolis-hypervisor-ahv\/<\/a>
\n
\nThird: If you have followed our recommendations and have N+1 setup, meaning 1 less Exchange server than total nodes in the cluster, you should simply be able to shutdown a CVM while Jetstress is running on that node and the test should continue and pass with impact of roughly N-1. e.g.: If you get 2000 IOPS in a four node cluster, you should see 1500 if you took one node out. This is what I have pbserved during these failure scenarios, the larger the cluster, the lower the impact. Importaintly, its a predictable and graceful degradation, not a \"fall off the cliff\" style issue.
\n
\nLet me know how you go, I'll aim to post the rest of the video in the Exchange performance testing series in the next few days.

我浏览了您提到的链接。实际上,在我们的情况下,我们使用一个6系列和两个8系节点。因此,在一个群集中,这种不同的模型是否有任何问题?customer在此群集上的一个Exchange VM上进行了Jetstress测试测试正在通过。他们想从节点上删除一个硬盘并进行测试。因此,一个硬盘而不是SSD从一个节点中删除并进行了测试,然后测试失败了。测试是否失败了。
在警报中看到的唯一一件事是所有节点上的NIC错误。因此,我们用Nutanix打开了nutanix的NIC错误,并且情况正在进行。
另外,我尝试访问http:// cvm-ip:2009。但是无法访问该页面的策展人页面,可能需要在我们的网络的firwall中打开该端口。但要访问策展人页面,任何步骤需要完成。
感谢您的回复。
问候
里奇·詹姆斯
\nI go through the links you mentioned.Actually in our case we are using one 6 series and two 8 series nodes.so is there any problem with this different models in one cluster?.customer has done jetstress test on one exchange vm on this cluster and the test was passing.and they want to remove one hard disk from the node and do the testing .so one hard disk not ssd was removed from one node and did the testing then the test got failed .even after adding the disk back and did the testing the test was getting failed.
\n
\nonly thing which was seen in the alert is nic errors on all the nodes .so we opened case with nutanix for nic errors and the case is going on.
\n
\n
\n
\nAlso i tried to access the curator page by http:\/\/cvm-ip:2009 .but not able to access that page ,may be that port need to be opened in the firwall of our network.But for accessing curator page ,any steps need to be done.

混合节点没有问题,实际上,在许多情况下,我们建议使用大型邮箱容量扩展或设计解决方案。
什么是Jetstress配置?我们的建议是多少数据库,每个数据库的大小,每个VM有多少个VDISK(每个db和一个logs是一个vds),对于DBS,在线压缩和无压缩/defupe/ec-X的在线压缩)。
如果您可以将此信息提供给我们的支持组织,请告诉他们与我联系,我可以提供帮助并查看正在发生的事情。
如果您收到网络警报,则可能会导致网络带宽/配置或组合问题,这会导致问题,但我只能在此阶段推测。
我们将解决它。
\nThere is no issues mixing nodes, in fact in many cases we recommend it when scaling or designing solutions with large mailbox capacity.
\n
\nWhat is the Jetstress configuration? How many databases, what size per database, how many vDisks per VM (one per DB and one per logs is our recommendation, with In-Line Compression for DBs and no compression\/dedupe\/EC-X for logs).
\n
\nIf you can provide this info to our support organisation, let them know to contact me and I can provide assistance and see what is happening.
\n
\nIf you are getting network alerts its possible a network bandwidth\/configuration or teaming issue is causing the issue, but I can only speculate at this stage.
\n
\nWe'll get it resolved.","quoteUsername":"joshodgers","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
我个人不必担心至少在此问题上查看2009年,我们知道交换/杰特斯的行为如何,群集/网络等是否正常工作,Jetstress会根据我的博客文章来传递。
让我们跟进支持票,因为我们想跟踪所有问题,以便我们可以更好地帮助客户未来的支持请求。
\nI personally wouldn't worry about viewing 2009 at least for this issue, we know how Exchange\/Jetstress behaves, if the cluster\/networking etc is working correctly, Jetstress will pass as per my blog posts.
