亲爱的，
一年多以前，我已经配置了3个节点Nutanix块（NX-1000系列），现在我们的客户要求将enew node（NX-3000 Serie）添加到现有群集中。节点不影响运行节点？

问候，
    \nI have aleady configured 3 nodes Nutanix block(NX-1000 series) more than year ago ,and now our customer requested anew node (NX-3000 serie) to be added into existing cluster.Could you please letme know the best way to add this node without impacting the running nodes?

    特殊限制适用于一些NX-1000节点 - 即，如果我没记错的话，您不能将1 Gig以太网节点与10 Gig以太网节点混合。但是，如果您的节点都是10 gig，那么您只需遵循标准添加过程，该过程不会影响Nutanix群集的可用性。史蒂文·poitras（Steven Poitras）有一个很好的博客 /w视频，添加一个新节点（如果它是一个节点或整个节点块，则没有程序差异）：

    感谢您的回复。
    具有3个节点的设备使用1G连接连接，因为客户环境没有10 g，并且还将使用1G网络连接新的节点3000系列。

    根据建议，Nutanix指南不采用此操作。1G开关无法处理流量。

    不建议这样做，但它会起作用，但是我有一个设置工作，但是，建议您的客户在可能的情况下升级到10GB开关，因为无法保证1GB的性能。

    1GB的问题基于在节点之间移动的元数据量。

    这来自Nutanix圣经（Steven Poitras）：

    看带宽
    对于传统存储，I/O有几种主要媒体类型：
    • 光纤通道（FC）[列表]
    • 4-，8-和10-GB
  • 以太网（包括fcoe）
    • 1-，10-GB，（40-GB IB），等。
    [/list]对于以下计算，我们使用的是500MB/s读取和460MB/s Write BW可从Intel S3700获得。
    计算如下：
    numssd = rougnup（（（numConnections * connbw（in GB/ s）））/ ssdbw（r或w））
    笔记：数字被四舍五入，因为不可能进行部分SSD。这也不考虑处理所有I/O所需的必要CPU，并假设无限制控制器CPU功率。
    饱和网络需要网络BWSSD
    控制器ConnecterAvailable网络BWREAD I/OWRITE I/O
    双4GB FC8GB == 1GB23
    双8GB FC16GB == 2GB45
    双16GB FC32GB == 4GB89
    双1GB ETH2GB == 0.25GB11
    双10GB ETH20GB == 2.5GB56
    如表所示，如果您想利用SSD可以提供的理论最大性能，则该网络可以成为一个瓶颈，根据利用的网络类型，该网络在1到9个SSD中的任何位置都可以

    \nThe problem with 1Gb is based on the amount of metadata being moved between the nodes.
    \n
    \nThis comes from Nutanix Bible (Steven Poitras):
    \n
    \nLooking at the Bandwidth
    \nFor traditional storage, there are a few main types of media for I\/O:
    \n
      \n
    • Fiber Channel (FC)[list] \n
    • 4-, 8-, and 10-Gb<\/ul>\n
    • Ethernet (including FCoE)
        \n
      • 1-, 10-Gb, (40-Gb IB), etc.<\/ul>[\/list]For the calculation below, we are using the 500MB\/s Read and 460MB\/s Write BW available from the Intel S3700.
        \nThe calculation is done as follows:
        \nnumSSD = ROUNDUP((numConnections * connBW (in GB\/s))\/ ssdBW (R or W))
        \nNOTE: Numbers were rounded up as a partial SSD isn\u2019t possible. This also does not account for the necessary CPU required to handle all of the I\/O and assumes unlimited controller CPU power.<\/i>
        \nNetwork BWSSDs required to saturate network BW
        \nController ConnectivityAvailable Network BWRead I\/OWrite I\/O
        \nDual 4Gb FC8Gb == 1GB23
        \nDual 8Gb FC16Gb == 2GB45
        \nDual 16Gb FC32Gb == 4GB89
        \nDual 1Gb ETH2Gb == 0.25GB11
        \nDual 10Gb ETH20Gb == 2.5GB56
        \nAs the table shows, if you wanted to leverage the theoretical maximum performance an SSD could offer, the network can become a bottleneck with anywhere from 1 to 9 SSDs depending on the type of networking leveraged","quoteUsername":"virtualizecr","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    但是看来我没有问这个问题正确！！！
    Nutanix群集工作正常。现在，我从同一型号购买了新节点，因此我想将其添加到群集中。最好的方法是什么？我是否需要再次使用基础来添加此节点？请为我提供完成此类任务的步骤。

    问候，
    \nBut seems that I didnt asked this question proper way!!!
    \nNutanix cluster working fine. and now I purchased new node from the same model so I want to add it into the cluster.what is the best way to do this? Do I need to use the foundation again to add this node? please provide me with steps to complete such tasks if available.
