• 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)

• 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.

• 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

  The virtual machine tools has been installed on the guest operating system

• Multiple NICs configuration

  Please guys, I could really use some help.  Even after RTFM, I felt how much a noob in fifteen years.

  I had a COMPUTER technician long lost preach the wonders of virtualization for me and I saw the light.  So 2 years later, I'm ready to give it a try on my first production server.  I did a few tracks of practice developing successfully, but I can't reproduce exactly what I feel when I do in production. Specifically associate network.

  I am to convert a VM supported Dell PowerEdge T620 from physical to virtual.  Right now the physical server has a production Oracle database.  It has 2 network cards physical, 1 connected directly to the internet and connected to the internal LAN 1. I use VMConverter and empty the contents of the server to another machine, install VM ESXi 5.1 on the server, and empty the contents of the original server in a newly created virtual machine.  I then created a second VM for use as a file server.  I tested on a separate machine with no problems EXCEPT that... the network settings.  What the hell I do?

  I think (scary) that I need is 1 physical NIC w / 3 internal IP (192.168.0.28 - Oracle, now VM1 original INVESTIGATION period), (192.168.0.29 - new fileserver VM2), (192.168.0.30 - virtual computer management).  The other physical NETWORK adapter should have just the Internet (24.23.x.x) IP address and will be available at VM1 since only the Oracle DB must accessible via the internet.

  Is this sound right and how Devil can I configure it?  I went through the Guides of the network, but I am more confused than ever with groups, ports, distributed switches, standard switches, etc.  Do I still need to go down this path?  My head hurts.

  Thanks for any help.  It's really appreciated.

  All network adapters must be attributed to a vSwitch, even if used by only a single virtual machine.

  In your case, you want to do this:

  NIC1--> vSwitch 1-> 1-> NIC on Oracle VM PortGroup (this virtual NETWORK adapter has the IP 24.x)

  Map NETWORK 2-> vSwitch 2-> 2-> NIC on Oracle VM PortGroup (this virtual NETWORK adapter is 192.168.0.x address

  -> NIC on other VM (this virtual NETWORK adapter will have address 192.168.0.x)

  -> vmkernel port (for management - new 192.168.0.x)

  Hope this helps.

• 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?

• 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.

• 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.

• 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:

• 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.

• Windows 7 multiple Gatways prof. is not networked

  Recently, I had buy new HP desktop Core i3 with 4 GB of memory & installed windows 7 32-bit Professional on this PC operating system. I have set up the two LAN cards on this PC with a different static IP & gateway to connect to internet and my Local network.
  Mr President, I found that one network card can work at a time, Local or Internet LAN network. two cards are does not sentimentally, the same configuration was working properly in my windows XP system.

  kindly help

  Hello

  When multiple default gateways are used in TCP/IP configuration on a Windows computer options, connectivity to computers on remote networks may be lost. On multihomed connected to disjoint networks computers, static routes can be added to the routing table to get connectivity to remote networks.

  Windows computers can be configured with multiple default gateways. When an inactive gateway is detected by TCP, he can direct IP for default gateways to the next gateway in the backup list. This switch can occur when there are multiple gateways configured for the same network card or when different default gateway addresses are given on multiple NICs on a multihomed computer. A switch is triggered when TCP has tried half of the time to send a packet through the current default gateway TcpMaxDataRetransmissions.

  After the passage, all IP traffic from any network adapter on this computer to remote networks will be sent to the gateway currently selected. On disjoint networks, this can lead to the loss of connectivity and subsequent termination of active sessions with computers on remote networks connected through the first gateway. This is because the selected gateway may not be aware of the other routes managed by the first gateway if routers Exchange routing information to each other.

  If the dial-up gateway is unreachable or inactive on the network, it loses connectivity to all remote sites. At this point, this computer from a remote network ping fails to get a positive response. Similarly, no ping to a remote host from this computer will give a request error. This behavior is normal and in line with the specifications of the TCP/IP.

  I suggest you check out the links below to solve the problem:

• vCenter - multiple network cards

  Hello

  I have a vCenter Server 4 U4 with multiple NICs for managing esxi connectivity etc. All ESXi hosts are connected via a dedicated card. For security reasons I must add one host to vCenter managed on one vlan separated / network card. Is this a supported configuration or a configuration that someone uses?

  When I add the host to vCenter it disconnects after about 60 to 90 seconds. All firewall ports are open and nothing is denied, DNS works very well, as well as the ICMP between vCenter server and the host. Any ideas?

  Thank you

  Good deal.  If the Windows Firewall looks like right check this KB: http://kb.vmware.com/kb/1008030

• Is a NIC enough?

  I just ordered the material for a new box of ESXi and I forgot to order a NIC extra 1 will be enough or do I need to get a couple more? Other than the throughput and redundancy, are there other benefits to have multiple NICs to a laboratory at home?

  Thank you

  Tony

  1 NETWORK card is not recommended and fundamental requirement for the production environment. There are many benefits in having multiple NICs on an ESXi host.

  1 isolate the different types of traffic NW as direction NW, NW VM, vMotion NW, NW, FT NW iSCSI.

  2 with virtual NW physical card by covering with the required VLANs.

  3. its recommended to have an extra NIC as redundant for HA.

  4. several uplinks will help you make a migrationf of uninterrupter of standard switch to vDS.

• Best network design... Need advice on the best use of NIC

  I'm new to the concept of Distributed Switch so I need advice.

  Our current environment is the result of a vCenter 4.1 and ESXi 4.1 Enterprise Plus, but we are just using the standard vSwitch (1 for vMotion/Console and 1 for virtual machines).  When the distributed switch came out, we were warned that a vDSwitch could cause us problems if the server vCenter or database is down.  We could not connect directly to the host and make network changes because the vDSwitch is set in the database.  That's why we stayed with the Standard vSwitch only.

  Our farm is quite small, only 5 hosts but we run around 100 mV in this regard.

  We use currently servers HP DL385 G7, which have 4 cards integrated network, and we have a map of installed NETWORK 4 port card.

  I use the NETWORK 4 EtherChannel ports and trunk card to our virtual machines.

  I am currently using only 1 network card integrated for vMotion and 1 for the Service Console and they all have two of the other defined as secondary.

  This configuration has worked very well for us, but I realize that the latest version of ESXi has some new features that we could use.

  NEW CONFIGURATION

  I'll put up a new vCenter 5 and ESXi 5 environment and I am considering using the switch distributed instead of the usual vSwitch we use.  I'm also eager to take advantage of the multiple NIC vMotion.  All our cards are 10/100/1000 MB capable... No. 10 GigE.

  I think... use that map 4 NETWORK ports for my EtherChannel/trunk for just as our virtual machine before, but this would be set to vDSwitch1

  The mixture of my 4 other integrated ports, it's causing me grief.  Should they be on a standard vSwitch or vDSwitch?  Use 2 ports for vMotion and 2 for the Console?  I really thought to use 3 ports for vMotion and 1 Console port.  I could put the Console port to use one of the vMotion ports such as adapter of standby is... I'm so confused freaking!

  Any recommendations on how I should put up?

  Hello

  Given that you can't split your vmnic for each vSwitch I would recommend either keep configuration simular with the knoweldge if a whole nic fails, you will take a failure or as autumn has already been mentioned on 'Origin Port ID'. Lets do this out and give a little better example

  Current configuration

  vSwitch0

  VMNIC0 - NETWORK interface integrated - Service Console

  VMNIC1-Onboard NIC - VMotion (different IP or VLAN?)

  VMNIC2-Onboard NIC - VMotion (different IP or VLAN?)

  VMNIC3 - NETWORK interface integrated - VMotion (eve of Console of Service) (different IP or VLAN?)

  vSwitch1

  VMNIC4 - extension PCI NIC - Etherchannel trunk - PortGroup - VMNET

  Extension VMNIC5 - PCI NIC Etherchannel trunk-PortGroup - VMNET

  Extension VMNIC6 - PCI NIC Etherchannel trunk-PortGroup - VMNET

  Extension VMNIC7 - PCI NIC Etherchannel trunk-PortGroup - VMNET

  Now, to captured to eliminate any single point of failure that you could do is break your Etherchannel trunk and back this vSwitch from Port ID and Setup VMNIC2, VMNIC3, VMNIC4, VMNIC5 as vSwitch1 for your VMNET. Then the cable to multiple switches eliminate any single point of faiulre. If your standard configuration would look like this

  vSwitch0

  VMNIC0 - on - Board Service Console

  VMNIC1 - Board - Vmotion

  VMNIC6 - extension PCI NIC - Vmotion

  VMNIC7 - extension PCI NIC - Vmotion (standby Service Console)

  vSwitch1

  VMNIC2 - VMNET

  VMNIC3 - VMNET

  VMNIC4 - VMNET

  VMNIC5 - VMNET

  So to finish any request for psyhical nics on this particular configuration the Port ID of origin essentially around robins. If during your first VM is online it will be use VMNIC2 and nic forever, until a failure, in which case he will grab the next nic online. When your second VM is online it will use VMNIC3 forever, until a failure and so on. This still will give you around the same way through to as far as networking is concerned. However if you are attached to the trunk, etherchannel 4 GB and can obsorb a failure in case of failure, the network card 4 ports can stay.

  Distributed switching Setup

  Allows you to see how you can switch to distributed switching

  Let's start first of all, you can have EVERYTHING in switches distributed even the service console port if you wish. The resason why some people do not like to do this with the service console port is because IF your database is broken you cannot make any changes to the distributed switch. However it will not prevent a feature to your distributed it switches simply means, you can change them. Also if just getting worse and your DB has been declining for some time and you REALLY need to make a change to the service console port you can go into the console and change back to a standard vSwitch if need be. This allows the said look at some standard configs, you can work

  vSwitch0 (Standard)

  VMNIC0 - Service Console Port (Port Original ID or standby)

  VMNIC4 - Service Console Port (Port Original ID or standby)

  vSwitch1 (Standard)

  VMNIC1 - Vmotion

  VMNIC5 - Vmotion

  Distributed switch

  VMNIC2 - VMNET

  VMNIC3 - VMNET

  VMNIC6 - VMNET

  VMNIC7 - VMNET

  Now this config using originating port ID and breaks your etherchannel if you want to keep your configuration with the etherchannel it can look like this

  vSwitch0

  VMNIC0 - NETWORK interface integrated - Service Console

  VMNIC1-Onboard NIC - VMotion (different IP or VLAN?)

  VMNIC2-Onboard NIC - VMotion (different IP or VLAN?)

  VMNIC3 - NETWORK interface integrated - VMotion (eve of Console of Service) (different IP or VLAN?)

  Distributed switch

  VMNIC4 - VMNET

  VMNIC5 - VMNET

  VMNIC6 - VMNET

  VMNIC7 - VMNET

  Other changes to the configuration may also put the vmotion in distributed witch the VMNET but you would to VLAN, or you could create a second Distributed switch and put it as long as there are 2 network cards. It can go either way. The main advantage of a distributed switch is that it brings all of your settings with you in any host. So trade ect all your VIRTUAL networks is really easy to reproduce if a new host is brought online, all you have to do is to add the new host network cards in the distributed switch and your config is done. With that in mind lets look at the service console. This console is always configured on EACH Setup program that out you of the box if not that you really need to have these parameters transported on several hosts that is another reason why most people just don't. VMotion is up to you, I have seen and configured two ways, it all depends on how simple you want to keep it or think of switching / vlaning / port of groups.

  If you have any questions please let me know, I hope this has helped
