it's installed by default please refer http://next.nutanix.com/t5/Installation-Configuration/Change-IPMI-network-settings-from-Prism/m-p/20334#U20334

Thanks in advance.

IPMI just like configuring Dell IDRAC or HP ILO if you're familiar with

KSD you can start with field installation guide

hi, can i understand the purpose of ipmi ?
I understand its like ilo or cisco's cimc, for hardware management portal.

my organisation has a block with 2x 10g switches.
Our current setup seems to work without ipmi connections and the guides i read implies ipmi as "should" rather than "must".

What are the impacts of not connecting ipmi ports ?

cclooIPMI just like ILO or CIMC if you familiar with. Cluster will run well without IPMI conncted you just can't manage the hardware remotely

Your cluster will run well without IPMI

But on the other hand, IPMI is really important when reinstalling the block by utilizing Foundation VM

hi guys,

thanks for the response.
I guess while IPMI is not a need to have, its still important.

I have been trying to eliminate the need of using the UTP port because the mellanox switch we have are QSFP ports and its really expensive to use 1 for a copper SFP.

In such scenario, i guess i'll setup a cheap 1g switch instead.

According to this diagram, the ESXi hypervisor still have internal communication with IPMI (purple arrows, bottom left)

Does this mean that even if the IPMI port is not connected to a switch, the hypervisor still have control over the hardware via some internal connection ? If so, what is the purpose of connecting IPMI into same vlan as CVM and ESXI ? I had this impression that the IPMI physical port is for human accessing instead of system communication with each other.

Within a node, hypervisor and CVM connecting to each other through the internal switch (running on 192.168.5.0 network)
You can verify this by checking the Network vSwitch on any hypervisor

For cluster connection, a node will use the virtual External switch with IP address assigned by you in the installation progress.
I think, the internal communication as shown in your diagram should be explaines as below:
Between ESXi and IPMI: For console remote connection as well as IPMI management commands, hardware information... (from hypervisor you can execute IPMI commands to control, modify IPMI parameters such as login infor)
Between IPMI and Foundation: Foundation VM use IPMI for automatical installation
Between CVM and IPMI: TCP port 22 and 443 (as SSH and HTTPs apps)

So the purpose of connecting IPMI into same vlan with CVM and ESXi is for easier in management connection between ESXi/CVM and IPMI.
You can assign CVM and ESXi to be run on a specific VLAN difference from IPMI VLAN and this network model should be also work with no problem even if in this case, cause of the internal connection, you can also control the ESXi host from IPMI management webpage
