大家好，

我想知道是否有可能为每种不同流量类型的bellow具有不同的VLAN ID/子网范围：
- 管理程序管理（ESXI）
- Nutanix群集管理
- nutanix群集复制 /自动训练

最好的是，甚至对不同的VLAN进行复制和自动训练。

这里的理由是遵守有关DMZ虚拟化的客户内部安全策略。
我们被允许使用VLAN，并且不被迫使用不同的物理端口，但是安全团队（全球银行）担心ESXI和Nutanix在同一VLAN上。

西尔万。

\nI was wondering if it's possible to have different VLANs ID\/Subnet range for each of the different traffic type bellow:
\n - Hypervisor Management (ESXi)
\n - Nutanix Cluster administration
\n - Nutanix Cluster replication \/ AutoPath
\n
\nAnd the very best would be to even have replication & AutoPath on different VLANs.
\n
\nThe rationale here is to comply with customer internal security policies regarding DMZ virtualization.
\nWe are allowed to use VLANs and are not forced to use differents physical ports, but the security team (worldwide bank) is concerned about the ESXi & Nutanix being on the same VLAN.

嗨，Shuguet，

将HV/ESXI MGMT流量放在单独的VLAN上应该没问题（甚至在安装指南中提到）

至于“ Nutanix群集管理”和“复制流量”，我目前不支持它。

为什么？
如果在vlan-visor（vswitch）级别上进行VLAN-SPLITUP，则在CVM中需要第三/第四个VNIC（为其他网络配置附加的IP）
CVM运行的Linux当然没有问题，但是我看不到对不同NUTANIX服务的任何配置支持。

如果您“向前” VLAN标记了CVM内部的流量，并在VM内进行拆分，那仍然是同一问题。
我看到的唯一（理论上的）方式是使用10G键 - 键入CVM内部配置OpenVswitch。vNIC作为上行链路（带有标记的流量）和原始Nutanix CVM IP居住的本地VLAN。另外，还有一些“ openflow/openVswitch-rule” - 魔术（在这里变得棘手：P）标签，例如复制流量不同。

荒谬：-)

编辑：您可以发布到建议框 /产品功能 - 类别。

\n
\nputting the HV\/ESXi mgmt traffic on a seperate VLAN should be no problem (its even mentioned in the install guide)
\n
\nas for the \"Nutanix Cluster Administration\" and the \"replication traffic\" i don't see it supported currently.
\n
\nWhy?<\/u>
\nIf doing the VLAN-Splitup on the Hypervisor(vSwitch)-Level, you would need a 3rd\/4th vNIC in your CVM (to configure the additional IPs for the additional networks)
\nWhich would be of course no problem for the Linux the CVM runs in, but i can't see any configuration support for the different Nutanix Services.
\n
\nIf you \"forward\" the vlan tagged traffic inside the CVM, and do the split-up inside the VM, it would still be the same Problem.
\nThe only (theoretical) way i see is to configure an openvswitch inside the CVM with 10g-bond-v<\/b><\/u>NICs as uplink (carrying tagged traffic) and a native VLAN of the primrary Nutanix CVM IP residency. In addition there is some \"openflow\/openvswitch-rule\"-magic (here it gets tricky :P<\/i>) which tags e.g. replication traffic differently.
\n
\nabsurd :-)

是的，我认为也许是带有支持帮助或其他内容的高级配置。
我很清楚UI的技术局限性，但是正如您所指出的那样，Linux VM对更加满意。

这只是添加该选项的问题，因此，如果现在不可能，我将接受您的建议并在建议部分中发布。

西尔万。

\nI'm well aware of the technical limitations of the UI, but as you pointed, the Linux VM would be more than happy with more vNIC.
\n
\nIt's just a matter of adding the option, so if it's not possible right now, I will take your advice and post in the suggestion section.

通过文档重新阅读使我想起了用于复制的远程命令的地址列表选项。

通常，您会将此参数用于CVM-IP-Addresses，但文档还谈论了理论（VPN）隧道地址。

对我来说，这看起来像您（至少从技术的角度来看）能够在CVM（以ESXI VSWITCH标记的其他VLAN（UN）中）添加第二个VNIC，并使用该IP进行复制流量。

（检查Cerebro服务是否在0.0.0.0上收听或界面是否绑定）

如果有效，nutanix可能会支持它。

我仍然想知道当时文档中的“隧道”评论。

\n
\nNormally you would use this parameter for the CVM-IP-addresses, but the docs also talk about an theoretical (VPN) tunnel address.
\n
\nto me this looks like you would - at least from a technical point of view - be able to add a second vnic to the CVM (in a different vlan, (un)tagged by ESXi vSwitch), and use that IP for replication traffic.
\n
\n(check if cerebro service is listening on 0.0.0.0 or if it is interface bound)
\n
\nif that works nutanix will possibly support it.
\n
\nI'm still wondering about then \"tunnel\" comment in the docs.","quoteUsername":"mluksch","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

描述
有时，网络设计需要CVM和ESXI主机在单独的网络上。电流版本的nutanix群集不允许使用此功能，并且HA.PY故障转移脚本无法正常运行。CVM网络中的地址分配给ESXI主机（除了CVM网络外主机上分配的主要管理地址外）。

解决方案
解决方法：

在每个ESXI主机上创建一个存储VMKERNEL PORTGROUP。

在CVMS的子网中分配一个IP地址。这将允许CVM与主机进行通信，以获取VM/CPU/内存统计信息的详细信息，并通过HyperInt API自动安装NFS数据存储。

从该端口组中取消选择VMOTION，管理流量，可容忍的日志记录和ISCSI。

将ESXI IP地址（您创建的新VMK）放在CVM的NFS-White-List中：

NCLI群集add-to-nfs-whitelist ip-subnet masks =“ x.x.x.x/n.n.n.n.n”

其中x.x.x.x是新的VMKernel端口组的IP地址，而N.N.N.N是子网罩。

重复您在步骤1中创建的每个新的VMKernel IP地址的步骤2（可选，您可以添加整个CVM子网）

\nDescription<\/b>
\nSometimes a network design requires the CVMs and ESXi hosts to be on separate networks.Current versions of Nutanix cluster do not allow this, and the ha.py failover script will not function properly.A workaround is detailed below, however this still requires the use of addresses within the CVM's network to assign to the ESXi hosts (in addition to the primary management addresses assigned on the hosts outside of the CVM network).
\n
\nSolution<\/b>
\nWorkaround:
\n
\n
Create a storage VMKernel portgroup on each ESXi host.<\/ol>
\n
Assign an IP address within the CVMs' subnet. This will allow the CVM to communicate with the host to get details of VM\/CPU\/memory statistics and automatically mount NFS datastores via the HyperInt API. \n
Unselect vmotion, management traffic, fault tolerant logging and iscsi from this port group.<\/ul>
\n
Put the ESXi IP address (the new vmk that you created) in the CVM's nfs-white-list:<\/ol>ncli cluster add-to-nfs-whitelist ip-subnet-masks=\"x.x.x.x\/n.n.n.n\"
\n
\nWhere x.x.x.x is the IP address of the new vmkernel port group and n.n.n.n is the subnet mask.
\n
\n
Repeat step 2 for each of the new VMKernel IP addresses you created in step 1 (optionally, you can add the entire CVM subnet instead)<\/ol>","quoteUsername":"comotoza","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

这是解决方案的一部分，但主要问题是拆分CVM管理和CVM至CVM复制。
由于第一种流量是管理（通常是路由/远程），第二种是存储（大部分时间L2，本地），因此将它们分成2个VLAN将很有意义。

西尔万。

Sylvain Huguet -2X Nutanix技术冠军2015-2016，法国Nutanix Connect Chapter Champion，法国VMUG首领，6倍VMware Vexpert 2011至2016

\nAs the first kind of traffic is management (often routed\/remote) & the second is storage (most of the time L2 only, local), it will make a lot of sense to split them in 2 VLANs.
