Multiple NICs configuration

Similar Questions

• Multiple NICs

  I have a user who has multiple NICs on their machine. Sometimes remote-scan checks the correct network card, sometimes it isn't. Is there a way to lock Remote-Scan to the network adapter that is saved?

  Default remotescan remembers the network adapter selected when it fires. Sometimes remotescan may fireup before that all network cards are online or initialized. There is a directive to say remotescan ini setting delay start giving so I hope that sufficient time for these cards to come. Or if you have any startup scripts, simply put remotescan to the end, etc.

  If, for some reason, this card has been disabled remotescan grab just the following in the list. The next time remotescan pulls up, since this new adapter is the last selected, he remembers that one.

• Tolerance of failure with multiple NICs

  Apologize if this has been asked before.

  I'll put up a vSphere 5.5 environment and I have NIC 1 GB for each host to devote two NICs per host for tolerance to failures.  I was wondering the best way to set this up to their maximum output.  I have implemented as a Multi - NIC Vmotion?  As noted here: VMware KB: Multiple-NIC in vSphere vMotion 5. Essentially using two groups of ports as FT-1 and FT-2.  Or what I need to do as a Multi-NIC iSCSI with separate vswitches and each vswitch with a Port Group.

  Thanks in advance.

  You run into a problem of flow when you use 1 NIC for FT?

  Currently FT only supports using a single network adapter (1 G or 10 G)

• configure multiple NICs

  Hello

  I have ESX server configured with SERVER-based storage.

  I have a card of 1 GB on each server.

  I bought 2:

  NIC HP NC7170 PCI - X Gigabit double

  Now I have an option to add 1 dual port card to each server.

  So I have 3 on each server gigabit ports.

  What will be the right way for the configuration.

  I'd appreciate links or explanation on this topic.

  THX.

• Increase throughput for iSCSI with multiple NICs

  I'm implementing a new host ESXi 6 using a Synology NAS as an iSCSI target. I have 4 nic of the Synology stuck in 1 connection, so it has 4 GB of throughput. So far, over my hosting provider, I have two nic I dedicated to iSCSI traffic. So far, I put vSwitch under 1 two NICs and I was playing with patterns. I put two 1 vmkernel network cards and set as active adapters. However when I watch the iSCSI network traffic I only see traffic on a network adapter. This of course caps my speed to 1 GB. I would like to be able to bind several network cards so I can get a flow more. I tried changing the selection of the path for the warehouses of data in Round Robin are therefore at least two active nic. But which always leaves me with two individual connections of 1 GB instead of 2 GB connection. Is it possible for me to get there or I'm better off just having several 1 GB NIC load balanced?

  I'm not familiar with the Synology. However, what is generally - in the case where the storage system supports - is to set up several uplinks on the side of the target of storage/as well as on the initiator/ESXi side, each with their own IP address. Once configured, you can use multiple paths to access the target. According to the capabilities of the target, Round-Robin (if supported) will send traffic through all the links, i.e. using the bandwidth of all the links.

• vMotion on ESXi5 is not using multiple NIC

  Hello

  I test 4 x simultaneous vMotion operations on the host ESXi5, and "thought" he was supposed to distribute the load between the two NICS in a config.  resxtop shows that he always uses one NIC someone can provide an overview?

• Best use of multiple NICS (collaborate with VIRTUAL networks or physcially separated)

  Set up my new production environment vSphere and trying to figure out the best way to set up the network.  I have pictures to illustrate, but the basic question is:

  1. use all NICS in a pool and VLANS to separate traffic - or -

  2 devote some physical nic to only certain things (VMotion, FT etc..)

  We use Dell R710 2 servers with 6 NIC of each.

  Our SAN is connected via zFCP iSCSI, see you in the group is therefore only for failover of emergency if environmental FC had to leave for some reason any.

  Please let me know which design you think would be the best.

  Thank you

  Hello

  Everyone says to separate the service of the VMnetwork console.  If I can separate the traffic of service with one console vlan why separate physically?  If something happens to the service console connection disconnects but my machines always communicate then I would have trouble.  Why not make sure that if the network paths are for machines that I can control the server VM?

  Your VMNetwork is one of network environments more hostile within the vNetwork as its arbitrariness and a point of attack if someone breaks into a virtual machine. If you have the virtualization management network attached to your VMNetwork is on, there is a VERY good chance that the pirate VM now will be used to launch an attack against the network of virtualization management. Given the current set of attacks there is a VERY good chance of success. For security reasons, you want your management network virtualization to be separated and protected by a firewall of any other physical and virtual network. Ideally on its own switches with output physical switch VLAN in use. However if you use VLAN physical switch then you put your trust in these spending patterns, so you want to increase your monitoring of these switches.

  Since the original post, I combined the iSCSI traffic because it is a failover of emergency only where my zFCP hardware has a problem.  The iSCSI link rarely go to never get used and I didn't spend 2 physical network cards to something that would almost never be used.

  You want to spend 2 links for iSCSI, if you still do not have a failover, you can the bandwidth and redundancy. Consider all the links of storage redundancy.

  Let me know what you think on the service console.

  When you use VLANS in the vNetwork you are automatically protected against most known layer 2 attacks, but in the pNetwork you are confident that your switch configurations you will protect. These configurations have been known to change and not necessarily for the better. Some say, it must break so for that to happen, but 1 problem of configuration and your SC is now attacked. Remember, once the virtualization management networks can be attacked they can probably be broken. I know a pen-Tester, which can do that in a very short time, and they will have your virtual environment.

  Protect the machine from service/management console, Client vSphere, vCenter servers as if they were gold, access to them implies access to almost everything. That's why VMware strongly recommends that you create another network of virtualization management a firewall of all systems on your system. That within this firewall that place you jump machines that run all vSphere SDK and vSphere client and that you use something like RDP to access these tools without their execution through your firewall. Make this thing increases the security of your global virtual environment of giant protecting your investment in the current batch of management network attacks. VLANs are not a security tool, they are a tool of separation of network based on the pNetwork is correctly configured, maintained and checked. VLAN security is based on the confidence in your pSwitches not something that is authoritative.

• T530 multiple display configuration

  I have the T530 with NVIDIA Optimus option that should allow a triple (two external displays and laptop LCD) display configuration.

  I was able to get a job with computer configuration portable LCD and two external displays on DisplayPort through the docking station.

  I found on some startup programs, I'm either stuck with just the laptop LCD as the view-only or that I am able to turn on a single screen. Sometimes a reboot it will change, sometimes it won't.

  What is strange, is that the NVIDIA Control Panel and the Windows display settings show all three screens LCD, I'm not able to turn on one or both of the external screens (even if I turn off the laptop LCD).

  Someone at - he found a solution to this problem?

  Thank you!

  Hi, admarsha

  There are available for your BIOS and Optimus updates that can help with this. The update of the BIOS can be found here and the Optimus update can be found here. Research on the file Readme for the Nvidia update, part of the update help issues related to several screens via a docking station, so it may be useful.

  Best,

• U2515H twinkle in multiple monitor Configuration

  I have a similar problem as reported here: http://en.community.dell.com/support-forums/peripherals/f/3529/t/19626679

  We have a problem with a 4, NVidia NVS 510 and 4 monitors Dell U2515H monitor configuration.  The monitors are connected via a cable HDMI/mdp.  Usually, a single monitor flickers at the beginning of each day and last for several hours before stabilizing.  Sometimes, a couple of monitors will wavers. We have a restart every night which takes place at 02:00.  All the device drivers and chipset are up-to-date.

  No indication of the potential causes?

  Given that each monitor is connected to its own port of video card, have you checked that each monitor has disabled DP 1.2?

  

  And the problem watching a different revision of A0x work are expensive?

• How to lock the desktop icons in a multiple monitor configuration

  Original title: lock the desktop icons - and display

  Working with Windows 7 Home Premium has a problem processing 2 pieces: no matter how many times I said I want the display screen appears on the monitor, the screen of the computer, every day he arbitrarily returns to the computer screen only. That creates the 2nd problem: the desktop icons that I have arranged for the largest monitor rearrange themselves to adapt to the computer screen. Is there a way I can lock the icons in this position that I used to be able to do? Or is it possible that I can keep the display to go back to the computer screen? (I'm careful to apply the instructions to display before the specified seconds elapse).

   

  Hello

  I suggest you to go through the steps mentioned in the link and the Coachman.

  On a system running Microsoft Windows 7, the desktop icons can be moved to positions at random during another monitor main screen.

• Start bar begins on a bad office in a multiple monitor configuration.

  I have my Windows 7 Home Premium machine series upwards with two monitors extended desktop display. I'm having a problem where sometimes, when I restart the computer, the start menu begins on the secondary display even if the icons are correctly located on the main display. I have to disable the secondary display and reactivate to solve this problem. It's extremely annoying; y at - it a fix for this problem?

  Rather than the deactivation and reactivation of the secondary display, follow these steps:

  1 - Check that the second screen is defined as primary in the resolution options.

  2 - the next time you experience the misplaced taskbar, unlock the taskbar (by clicking on the right) and then dragging it to the correct location.  The taskbar will remember this post - that it cannot do when it is placed automatically during the installation of multiple monitors.

• SearchIndex.FindByIP () for VM with multiple NICs for

  If a virtual machine has multiple vNIC and each vNic has its own IP address, the SearchIndex.FindByIp () can support

  VM search based on any of the IP address of the interface of the virtual machine, or the API only supports

  VM look after the IP corresponding host name of the virtual machine?

  Hypothesis: VMware Tools is running on the virtual machine (which is not the case in my lab environment, where)

  I can't test out easily).

  Thank you.

  Hello - I have tested in my lab - SearchIndex.FindByIP () is able to find another IP VM - not just a primary address-based

• VDI connect to the virtual computer with multiple NICs, use wrong address

  Strange question, we are the double of a VM to autoguiding.  Each NIC is on a different network, and it works very well.  Except when you sign out of the VM with a zero client.  If both network adapters is enabled through the vsphere, zero client the client tries to connect to the virtual machine using a wrong address.  He will try to use the address 172.16.x.x, but the life of the virtual machine and is stored on 192.168.x.x network.  Is there a way to make the NETWORK on 192.168.x.x address network card that zero the client tries to connect?

  Using the network-> Advanced-> advanced-> tab connections maps and links, move the 192.168.x.x network adapter to the top of the list of connections.

• Multiple NICs on a virtual single linux machine

  It seems like it should be simple, but when I assign two adapters for a virtual machine linux simple, the virtual linux machine stops as soon as it finishes the set-up and the fact over and over again endlessly.   He made a clean shutdown, I look at the console, I see it start to stop all the services at the time wherever he gets all a started.

  It started as soon as I added a second network adapter, and the problem disappeared as soon as I removed the network card.

  What I'm trying to do, is to have a second network adapter on a separate network that I use to communicate with one another physical machine on my network using a static internal ip address.

  I have set up a separate virtual switch, which possesses the second network card are entrusted to him.   There is only a single guest that uses this adapter.    Does anyone have any ideas why this would cause CentOS5 keep close and restart constantly?

  Sorry, in my previous message, actually one-liner I wasn't very clear.

  I mean, what happens when you configure the virtual computer with a second NETWORK adapter, and then restart the virtual machine in Single-user Mode od recovery mode?

  Is the virtual machine responds the same way or not?

  The idea is to start the VM with less service so that it continues to run and you will be able to do research on the second NETWORK card

• A guest can fill multiple NICs (two)?

  I have two network cards on my host:

  • NIC1 - Internet and corporate LAN

  • NIC2 - engineering LAN with two static IP addresses

  Under my host, I can develop software of casings that can connect to devices on the local network using the NIC1 company to navigate the Internet.  There that somehow a VM guest can be configured in the same way to fill both NIC1 and NIC2 LANs?

  It seems that I can only access one or the other.

  Thanks in advance,

  -Ed

  Ed - assignment of the two real networks to a single virtual map of the guest makes no sense at all and is not possible

  You must assign two virtual network adapters to the guest as listed here:

  ethernet0. Present = 'true '.

  ethernet0.startConnected = 'true '.

  ethernet0.virtualDev = "e1000".

  ethernet0. ConnectionType = "custom".

  ethernet0.VNET = "vmnet0.

  Ethernet1. Present = 'true '.

  Ethernet1.startConnected = 'true '.

  Ethernet1.virtualDev = "e1000".

  Ethernet1. ConnectionType = "custom".

  Ethernet1.VNET = "vmnet2.
