Cisco UCS 5108 add NIC to ESXi host

Hello

I'm quite new in the world of the UCS, so I slowly read up on it. We currently have a laboratory with a 5108 that host two of our esxi5 servers. When I say lab, I mean a configuration that is not in production yet, and if I can use it to learn right now. I just now each server I create gives me only 2 network cards to work with, so I would like to add. I have attemtpted to add a new network adapter for the service model and apply it, but I get the following error.

"There are not enough global resources. Not enough available vNIC.

I don't know what I'm doing wrong or if 2 is my limit.

Thank you

Welcome to Dennis,

The quantity of NICs you can create depending on the model of the adapter.

E.g.

See the diagram below for the virtual interfaces supported by the adapter model

When you use the VIC M81 maximum interfaces that you create also depends on the number of links between IOM (chassis) and interconnections of fabric).  56 is assuming that you have 4 links of each fabric of interconnection of each IOM.

In addition, blades of large width (B250, B440) can support two adapters mezz, so you can adjust the vnic/vhba max.

Kind regards

Robert

  • Configuring the Cisco UCS 5108 ports

    Hi all

    I'm new in the world of the Cisco UCS server and am setting up Cisco UCS 5108 blade server. The server has two Cisco UCS 6324 interconnections fabric I did the initial Setup on and I try to configure the ports for the blades. Looking through the various articles and tutorials after setting global policies, I see the whole world establishment of uplink and server ports. What I read the uplink ports are plugged directly into the switches (I work with two cisco nexus switches), and server ports are used to connect to the chassis.

    I wonder once the configured ports server what exactly are supposed to connect to? I assumed they would also connect to the switch nexus with the uplink ports. However, every time I set up the server ports and plug them in, the switch doesn't seem to have flooded and we lose all connectivity. If I unplug, the connection is restored almost immediately.

    The current configuration, that I work with is two ports uplink on each fabric interconnect (4 2 total in each switch of nexus), two server ports on each (4 2 total, in every nexus switch). The only other element connected to the nexus switches is a SAINT who will be configured as a boot and storage of the UCS 5108.

    Looks like you have a Mini UCS (6324), with 4-port 10 GB (each FI/IOM) with port QSFP 40 GB that can provide network connectivity linking rising, or if configured as a server port, could be used to connect to a server in a rack compatible Cisco UCS, or connect to a 5108 additional with IOM 2204XP chassis.  The blades installed in your initial 5108 chassis 6324 FI/IOM of housing have internal connectivity to the FIs / IOM without the need to configure ports 'server'...

    Please take a look at some of the visuals in the datasheet below.

    http://www.Cisco.com/c/en/us/products/collateral/servers-unified-computing/UCS-6300-series-fabric-interconnects/datasheet-C78-732207.html

    Unified ports can also be configured as a FC ports for connectivity of FC switch upstream or directly related to CF Storage processors.

    After having watched the datasheet, let me know if you have any other questions, and I'll try to address them.

    You'll not need actually configure ports such as ports 'server' unless you connect servers in a rack.

    Please configure any ethernet SFP type connected to your switches nexus upstream as 'network' uplinks.  I guess that you don't plan on a disjoint config layer 2 (where each FI has several sets of uplinks will different devices upstream, or the same device with different VLANS allowed on each link).    If you are, we can have a separate thread about how you need to configure that.

    Thank you

  • Adding secondary management NIC to ESXi host

    Hello

    We currently have a customer demand to add secondary management NIC to the ESXi servers ourselves and the client can connect to hosts if vCenter becomes unavailable.

    Is someone can confirm if it is feasible or will host blend and become inaccessible? Sorry if this is an obvious answer, it's just that I have never seen configuration with management NIC

    Thanks in advance.

    We currently have a customer demand to add secondary management NIC to the ESXi servers ourselves and the client can connect to hosts if vCenter becomes unavailable.

    Can clarify you what exactly you mean by that? A single management interface are accessible by some many different clients, as long as it is accessible. Are there limits where the client manages the ESXi host from an internal network and you need to access externally via public IP, another for networking?

    In this case your would create a management interface 2nd vmkernel on the external network and to face together the default route of the external gateway routing and insert static routes for the internal network using the internal network gateway. So basically the same thing you would do to any IP multi-hosted system.

    Hallo,

    Basically, "vem version - v" but for all the ESXi hosts connected to a vCenter.

    I suspect you could use PowerShell v1, in this version that the Export-Csv has not had the UseCulture parameter.

    Try to run the script without this parameter.

    But I would strongly suggest to upgrade your version of PowerShell (v3 is available)

  • Service profile of the CISCO UCS for ESXi

    Do you need multiple boot LUN on the storage array for each host that you want to apply the service profile to? I'm just confused, let's say I have 12 blades that I want to designate as boot SAN for ESXi, y aura-t 12 profiles of separate service for each of them, and will need me 12 different LUNS on our storage? I am new to this and I just want to make it as clean as possible! Any help is appreciated.

    Hi Justin,

    You can have the same LUN ID for multiple service profiles, as well as the same target ID. However, your initiators will be different and you will need to configure the zoning on your switch upstream if you use the end host mode.

    Here is a good guide, review the basics and how to put in place.

  • Add ESXi hosts to vSphere Client

    We have 7 servers ESX and ESXi 8 servers.

    Six of the ESX servers are sitting in a cluster and the last of them is located in its own cluster.

    It's nice to manage all 7 ESX servers in a vSphere Client.

    8 ESXi servers, I've been managing each with their own vSphere Client connection.

    Is it possible to create a cluster of ESXi in vSphere and add each of the ESXi hosts to this cluster of '? Or even a "cluster"?

    I tried and I get the following error.

    "License not available to perform the operation. ESXi 4 for Host 192.168.1.10 Server license does not include the agent for ESX Server vCenter. Upgrade the license. »

    We don't have a budget to upgrade the more liceneses. I don't mean to make HA or DRS on the ESXi hosts. I'd just like to see servers running on them for purposes of inventory without having to have 9 vSphere customers open.

    We have a license entirely vCenter Server so I think we should be able to add these ESXi servers.

    Any help would be appreciated.

    You must have at least vSphere Standard license for each host you wish to manage with vCenter. Free ESXi cannot be connected to vCenter.

  • Cisco UCS C240M4 Esxi installation version 5.0 cisco custom image do not start

    Hi all

    We are trying to install ESXi 5.0 on Cisco UCS C240M4 server and during loading of the VMware purple screen with the following error

    Bora/vmkernel/hardware/apic.c:1913 and bora/vmkernel/hardware/apic.c:1915 NOT_IMPLEMENTED NOT_IMPLEMENTED.

    Greetings.

    ESXi 5.1 U2 is the first supported by Cisco for the C240M4. See matrix interop

    I suspect that older versions 5.0 and earlier versions will have problems with the latest chipsets, as well as the lack of 12 GB storage controller drivers.

    You will want to check the interop matrix for which OS versions are supported as well as different levels of driver for the network cards, storage, etc.

  • Do I need an IP NIC of each Esxi host address?  VMs needs access to the storage network?

    Hi all

    The issue go, I have a host machine with 3 nic cards - > 1 for production network, 1 for the management network and 1 for the network backup.

    The guest PC VM inside will be connected to the 3 network,

    But for the host himself, will be used for management and backup only.

    T1) is the bears from production on the need for level ESXI host having an IP address as well?

    =================================================================

    Right of Q2) now my host use internal storage. If I'm to migrate to a SAN storage, I have 1 more network for storage.

    I understand that the configuration of virtual machines and their data are assigned and stored in the data store that is made visible at the level of the host.

    They must for the virtual machines access the data store, join the storage network as well? or they are access to the storage through the host

    ================================================================

    Kind regards

    Noob

    T1) is the bears from production on the need for level ESXI host having an IP address as well?

    A NIC itself does not require an IP address. Which IP addresses are required for VMkernel port groups (for example, networking, vMotion, storage access,...) as well as virtual machines.

    Right of Q2) now my host use internal storage. If I'm to migrate to a SAN storage...

    No, a virtual machine (i.e. the guest operating system) does not require access to the system of storage, only the ESXi host.
