IP address of server blades management

Hello

Could someone please help me know which path is followed to reach the ip addresses of the server blade chassis management? To be more precise, to say that I have the management interfaces of interconnections connected to the switch network management of my fabric. When I ping addresses it ip of the blades, that ping through the management interface of the FIs management? Can I assign different subnet IP subnet Management Server as the FI management interfaces?

Also, could someone share a document illustrating this architecture?

Thank you

Hi Quesnel

Let's be very clear: IP address management blade = IP address of the MMIC, you can for example. access by the KVM.

There are 2 modes:

- out of band which is accessible on port 1 G of the interconnection of fabric management

- in the band which is accessible via a fabric interconnect 10 G uplink interface

See the discussion in

https://supportforums.Cisco.com/discussion/12185011/management-blades-OU...

Management in-band MMIC

A determinant to provide access management in-band for integrated management Cisco (CIMC) controller is the desire to separate traffic treated tenant provider cloud for service provider deployments shared, public or private. Out of band (OOB) management traffic is at the fabric of interconnections and cross management via the management port. This has the potential to cause bottlenecks and affect the bandwidth of the processor in the management ports.

In-band management allows MMIC traffic to take the same path as the data traffic into and out of the fabric of interconnections via the uplink ports. The highest bandwidth available to the uplink ports means that inband access greatly accelerates the management traffic and reduced risk of bottlenecks and the stress of CPU. When out of band (OOB) and inband address pools can be configured for access to the administration in Cisco's UCS Manager. Out-of-band access only supports IPv4 addresses. Access inband supports IPv4 addresses and IPv6, which allows a management single or double stack.

The two addresses of OOB management interface that can be configured in Cisco UCS Manager blade and rack servers are:

  • An OOB IPv4 address assigned to the physical server via the pool global ext-mgmt
  • An address IPv4 OOB derived from a service associated with the physical server profile

In addition, up to four inband management interface addresses can be configured:

  • A tape attributed to the physical server IPv4 address
  • An IPv4 address of inband derived from a service associated with the physical server profile
  • An IPv6 address band attributed to the physical server
  • An IPv6 address of inband derived from a service associated with the physical server profile

Several in-band for each server management IP addresses take additional sessions of CIMC. When you configure the OOB, and strip addresses, users can choose from a list of these addresses in the KVM Console dialog box when they launch KVM from a server, SSH to the ground, a service profile, the KVM Launch Manager or Cisco UCS Manager GUI web URL.

MMIC inband access supports the following services:

  • KVM console

  • SSH to MMIC for soil

  • vMedia of ISO, virtual CD/DVD, removable disk, floppy drive


Note

Only Cisco UCS M3 and M4 servers support access in-band MMIC. Access Inband MMIC for Cisco UCS M1 and M2 servers is not supported.

  • Reference Dell R310 Server Blade not start CD ROM [FRESH WINDOWS SETUP]

    Hello

    I have a Server Blade Dell R310. I created the virtual disk on a Raid Configuration, also I updated the BIOS boot.

    I PERC S100 when I checked on my configuration tab.

    The scenario is that I want to install a new / new copy of Windows 2008 R2 on this server, I have the dvd bootable. but when I put it on the drive it says "No Bootable Media found" something like that.

    Y at - it all the configurations that I missed? hoping to get answers from here.

    Kind regards!

    OK, let's back up a bit:

    Use the management tools of systems and Documentation (GDPS) instead of SBUU.  If you use SBUU with 2008R2, you should use the Driver Pack too... MUCH easier to use the GDPS, which has everything you need in there:

    FTP (you will need to copy/paste - forums do not like the FTP links):

    FTP://FTP.Dell.com/secure/FOLDER01538030M/1/OM_SMTD_730_A00.ISO

    Yes, you start on GDPS, follow the instructions, and then insert the 2008R2 media when prompted.

    Hey people,

    strange things occur yesterday evening. I bypassed about 120 messages "threshold crossed: CAW: etherTxStats...» "and"IO Module Warning.

How the database for me to work with Management Studio? Glaust

    Glaust, did you eventually get this working or is this even a question? If you can provide a little more information about what you were doing to import you talk. Am I right in assuming that your instance of SQL Server has the database is available for you to access through SSMS. Then, you have completed the import and now you can see the DB in the SSMS DB tree but you get the error and are unable to access the DB?

    It is usually a temporary error during hostname resolution and means that the local server does not valuationauront of response from an authoritative server.

  • vCenter Server and Manager on the same virtual machine and on the same host ESXi update that they manage

    Hi all

    I have a question to which I did not respond.

    I have an ESXi 5 on Proliant DL380 G7 server host. I want to install vCenter Server and Manager Update on one of the Server 2008 R2 VM on the same host. I know it's possible, but my question is how Update manager will provide updates to the same ESXi host it will run on? The update is applied every time host must spend in maintenance mode and power off the virtual computer running on this subject which means he'll kill VM where vCenter Server and Update Manager is running and the update will fail right?

    Is that possible at all or the VCS and UM such as a virtual computer operating point is updated to other guests if you have them or vMotion as VM to another host when you want to update the VCS and UM host is running?

    Thanks in advance.

    It will not work.  You will need at least two hosts.  This way you can vMotion the vCenter VM to another host.  From there, you can use VUM.  Otherwise, you will need to patch the host as a stand-alone host.

    Hello

    A 3850 catalyst switch has VLAN 20 (10.18.4.32/29) defined on it, which has a 10.18.4.38 gateway:

    D01-01-BWY #show ip short int vlan 20
    Interface IP-Address OK? Method State Protocol

  • on the side of client vpn ip address Apple Server help

    Hello

    i've got server apple running on a mac mini running yosemite and I put it in place for the vpn and everything works well on the server-side and client-side. I have what may be a stupid question so patient with me. When I'm on my machine client and vpn is connected, in order to access the storage disk, I have running on my server I have to enter the static ip address, that I attributed to my server. call 192.168.0.14. My question is: what happens if my router on the client computer affects 192.168.0.14 on a device? This results in a conflict? can I assign a static ip address within a range of numbers greater than my server so it's less likely to happen? I'm worrying about something stupid? I'm doing something wrong? Thanks to a light that you can throw on this dilemma.

    George

    Your network server should not be in the same subnet as the network that you are from the connection.   Which means that subnets 192.168.0.0/24 and 192.168.1.0/24 - is the range 192.168.0.1 to 192.168.1.254 - should be avoided.   Better to use a subnet or block 172.16.0.0/12 one subnet in the 10.0.0.0/8 block.  Usually a 24 (255.255.255.0) subnet somewhere in the range of 172.16.0.1 to 172.31.255.254 or 10.0.0.1 to 10.255.255.254, respectively.

    If you are entering the IP address of your server, then the DNS server is either not properly configured the address IP of the DNS server is not communicated to the VPN client or there is something other odd here.

    If your 'router' - probably a gateway box IP offering a combination of IP, NAT router, firewall, port forwarding, and Server features DHCP - past through apparently, built-in DHCP server IP address then you want set up to prevent it to the addresses that you have assigned statically.   In other words, the DHCP server should not be configured with a pool of available IP addresses that include statically assigned IP addresses.

    If you prefer, you can have your OS X Server act as DHCP server and disable the DHCP service in the IP gateway.

    The features and configuration and management of the gateway box varies.
