5.1 ESXi management no connectivity network with two network adapters connected

• ESXi 4.0 host network adapters

  I'm kinda a noob here, so forgive me if this is a stupid question. I have an ESXi host with two network adapters. My configuration is to have an adapter connected to the Internet and an adapter connected to my internal network. I want to do in order to implement an router ISA in a VM and use a NAT to clients internal and other virtual machines. Is this possible?

  I thought it would be as simple as the external adapter with DHCP configuration to obtain the address of my ISP and configuration of the adapter internal staically and then simply using vSwitches to connect the adapters with my computers invited to use the appropriate physical card. The problem is that when I go in the shell of ESXi, you can only configure dynamic or static for the management network and there is no options to configure two adapters separately. I see my internal adapter properly configured with a static address in the vClient, but the external adapter shows a range of IP addresses observed of 10.229.128.1 - 10.229.129.254. Where did that come from? Do I need to use the command-line utility to configure this? If so, what commands can do that? Thanks in advance!

  No need to reboot the host. Basically, all you need are two vSwitches. The first one connected to the LAN internal groups of 2 ports, one for the VMKernel (with the configured IP settings) and one for the network of the Virtual Machine. The second vSwitch only requires a Virtual Machine port group.

  Configure the virtual machine (your router ISA) with two network cards virtual, a related internal and external vSwitch. Make sure the settings for virtual network cards are set to "Connect at Power On" and are in the 'connected' State when the virtual machine is up and running.

  Depending on your ISP, you should get a DHCP IP address on the external vNIC by configuring it to "Automatic" in the guest OS.

• How many network adapters I - ESXi 4.1 with iSCSI

  I was wondering if someone could help me give a sense the news I read on # NIC for ESXi 4.1.  I came across the following article, but I'm not sure I understand all parts of traffic that he speaks:

  http://livingonthecloud.blogspot.com/2009/09/ESXi-networking-best-practices.html

  At the moment I have 6 cards 1 GB on each of my 3 servers.  I connect to my SAN via iSCSI, so I know I'm going to need at least 2 of these network adapters for that traffic. I know I'll need at least 2 NICs for connection between my ESXi server and my switch to the network of the VM.  What I don't understand is what I really need for the VMKernel FT, VMkernal Vmotion and VMKernal the Network Administration.  I do not plan on using Vmotion very often at all, so I'm not concerned about its impact on my network.

  Any advice?  I need to replace my double NICs with Quad NIC card or is it exaggerated?

  The management doesn't have a dedicated network card. It can share the network with virtual machines cards.

  In this case the following configuration would be interesting:

  vSwitch0: (3 NIC uplinks) (assuming vmnic0, vmnic1 vmnic2)

  Port group 1 - networking (vmnic0 and vmnic1-> active vmnic2,-> stand-by)

  Port group 2 - network of the VM (vmnic0 and vmnic1-> active vmnic2,-> stand-by)

  Port 3 - VM Network Group (vmnic0 and vmnic1-> stand-by, vmnic2-> active)-for the "Pervasive SQL.

  vSwitch1: (1 NIC/uplink)

  Port group 1 - VMkernel for vMotion on a separate network (192.168.x.x)

  vSwitch2: (2 cards network/links rising)

  configuration by following the best practices of your iSCSI storage provider

  In this way the "Pervasive SQL" would have a dedicated NIC (vmnic2) and may switch to another NETWORK card in the event of disruption of the network.

• Question quick bonehead: ESXi management network?

  Hello

  Didn't find it in the docs still... Managing IP network that is configured on the ESXi console:

  Does it become part of any another logical network later, for example the VMotion network - or is it independent?

  I'm trying to find out where to place; so far, I have:

  net iSCSI (private)

  NET vMotion (private)

  NET management (LOM and other things)

  Main DvSwitch (public internet)

  I assumed that the ESXi management IP is purely the hook to vCentre control one or several hosts - in which case, for us, it could logically go on the net public or management of the net, as long as he has a gig connectivity - would it be a reasonable assessment?

  Thank you very much

  Tim

  The net vMotion fit into this net managemnet - or is it physically separate?

  No, vMotion traffic moves the load of the computer virtual from one host to another. This traffic is not encrypted and so - for security reasons - the vMotion network must be a separate private network. Depending on your topology (1 GB, 10 GB), you can consider using cards dedicated for vMotion to provide the necessary bandwidth.

• URGENT! Two physical network with two subnets completely - no bridges - interface cannot connect both

  This is my urgent problem:

  I have a physical machine with two physical network interfaces. I have a VMWARE player and a virtual machine that must use cards on two different subnets, a public directly to the router and an intranet within the company.

  How can I just say a net card to go on this submarine and the other on the public void?  Go crazy. Help, please.

  Thank you

  P.

  Use the virtual network editor VMware Player, create an additional bridged VMnet and bind each bridged to a different physical network... card VMnet on a virtual machine, create a virtual network adapter on each subnet and bind each virtual network adapter to an another VMnet jumpered.

• Make a little a bood by setting the switch 1 VLAN other than ALL - lost to ESXi management

  Hi all

  As the title says, I mucked this up a little bit. I have two virtual switches configured, one with all my virtual machines on three cards attached network, and the other with the management and interface card NETWORK attached.

  I thought that I have would combine the lot in a single switch and have the cards connected to the simple switch. Everything is VLAN'ed switch0 was set up at the trunk all the VLANS, as was the segment of management - although this should be in one VLAN specific. I've updated the Switch0 simply use the VLAN segment management and connectivity quickly lost the device to ESXi. All virtual machines on their VLAN specific are OK on the second switch.

  How can I return a network access ESXi?

  Console access is available, but I seem to have lost Out Light control will have to physically go to the machine.

  What a prick!

  Chris

  Couple of questions to understand the actions performed by you:

  I've updated the Switch0 simply use the VLAN management segment, and quickly lost connectivity to the device ESXi--> do you mean WHAT VLAN ID changed to 18 0 (none)?

  

  The virtual switch was set to pass all THE VLAN the Port VMkernal (Management Network Group) has been updated with "All THE VLAN", I went it to the VLAN (18)-->, you gave VLAN ID as 18 and your single NIC - VMNIC 0 is interconnection to VLAN 18?

  In simple words - you physical NIC 0 visibility to VLAN 18 or not (you will have to ask Admin network) - double else check your wiring asks that you made at the time of Installation

  For this kind of connectivity issues - you need problems like RSA/ILO/DRAC remote console based on the style of the material.

  Hello

  The profile used is taken from your provider's SIM card - do not try to create one yourself. He usually works with the settings.

  Try this:
  1. disable the 3 G module and exit the Wireless Manager.
  2. wait 5-10 seconds.
  3. turn on the 3 G module, and then open the Wireless Manager.

  Should work?

  I have the problem that the module disconnects after a while. After it is not possible to reconnect because the Wireless Manager does not respond or I get a problem of downtime as yours.

• VMware device with 2 network cards claiming the same IP address with two MAC addresses

  Hello.

  I see messages intermittent my gateway network two MAC addresses associated with a virtual machine running on a 5.5 ESXi host for the same IP address.

  The virtual machine is a MiTel 3300 controller for a VOIP system. the system is configured with two IP addresses, one on the local network and another with a public IP address in the DMZ. In the network configuration of the 3300, I assigned the address LAN IP at 00: 0C: 29:30:B2:B2 and the DMZ IP at 00: 0C: 29:30:B2:BC (Mac for network devices presented by the ESXi host virtual machine).

  On the host, I configured a vSwitch with exclusive access to two physical network adapters on the host machine. The vSwitch is configured with two machine virtual port groups, LAN and DMZ, with access to the physical network interface cards. Tab grouping of groups vSwitch port NIC, I replaced the order of failover of the switch to activate an active NETWORK card only for the Group of LAN ports and the other card NETWORK only for the DMZ port group. (I don't know how the content of the column of networks is determined. Neither is correct for the traffic on the physical switch. If these are configurable, please advise and I'll change the settings). The relevant parameters of vSwitch, groups of ports and VM are distinguished below.

  On the virtual machine itself, through the VMWare host, I assigned 00: 0C: 29:30:B2:B2 for the Group of LAN ports and 00: 0C: 29:30:B2:BC to the DMZ group port (best I can tell, anyway, since the MAC address field annoyingly obscures the last two digits of the MAC address - break if I invert the mapping) (, but all seems OK).

  The goal here is to make sure that MACs of ports vSwitch the 3300 is listening and sending always correspond to the physical ports that are VLAN Tag by the physical switch to ensure the routing. Generally speaking, it seems that what is happening but, intermittently, we cross one-way calls that suggests a problem of routing between us and our SIP trunk provider; coinciding with these incidents, I get an email along the lines of "the security in the network device has detected a conflict of IP address with two or more devices. The period of INVESTIGATION "DMZ. DMZ. DMZ. DMZ' is claimed by the following clients with MAC addresses: ' 00: 0C: 29:30:B2:B2' ' 00: 0C: 29:30:B2:BC'. »

  I did something in the configuration that would lead to this kind of collision intermittent? Have a hacked together a way to do something that could be accomplished in a way that is simpler and more reliable?

  Thanks for any idea that you can offer.

  Kind regards

  J.

  

  

  

  I probably don't fully understand your configuration, but it seems that you are not interested in using the collection of NETWORK adapters in the virtual switch of the VM MiTel 3300.

  If it is correct, why not create two virtual switches, each with a group of port (LAN and DMZ) unique and with a separate connection of (vmnic2 and vmnic1)?

  In general, collection of NETWORK adapters may be used to share traffic between uplinks and ensure that if one of the uplinks connect fails, a virtual machine still has access to the network.

• Best practices for network configuration of vSphere with two subnets?

  Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

  Install the most common iSCSI would be traffic between hosts and

  the storage is not being routed, because a router it could reduce performance.

  If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

  MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

  vMotion a deployment scenario might be something like:

  NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

  standby

  NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

  NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

  NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

  VMK (192.168.4.10) active

  You would place you on VLAN 10 storage with an IP address of something like target

  192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

  gateway configured in ESXi would be the router the VLAN 20 with an ip address of

  something like 192.168.2.1. I hope that scenario help set some options.

• Poor ESXi 4 NFS Datastore Performance with various NAS systems

  Hello!

  In testing, I found that I get between a half and a quarter of the e/s inside a guest performance when ESXi 4 systems connect to the using NFS data store if the clients connect to the exact same NFS share.  However, I don't see this effect if the data store using iSCSI or local storage.  This has been reproduced with different systems running ESXi 4 and NAS systems.

  My test is very simple.  I created naked CentOS 5.4 minimum installation (completely updated 07/04/2010) with VMware Tools loaded and the creation time of a file of 256 MB using jj.  I create the file on the root (a VMDK stored in different data warehouses) partition or a directory of the NAS mounted via NFS, directly in the comments

  My crucial test configuration consists of a single test PC (Intel 3.0 GHz Core 2 Duo E8400 CPU with a single Intel 82567LM-3 Gigabit NC and 4 GB RAM) running ESXi 4 connected to a printer HP Procurve 1810 - 24 G, which is connected to a VIA EPIA M700 NAS system running OpenFiler 2.3 with two 1.5 to 7200 tr / MIN SATA disks configured in front of software RAID 1 and dual Gigabit Ethernet NIC.  However, I have reproduced it with different ESXi PC and NAS systems.

  This is a release of one of the tests.  In this case, the VMDK is a store of data stored on the NAS via NFS:

  The first dd is a VMDK stored in a connected via NFS data store.  The dd ends almost immediately, but the synchronization takes nearly 40 seconds!  It's less than 7 MB per second transfer rate: very slow.  Then I get the exact same NFS share that ESXi is used to store data directly in the comments and repeat the DD.  As you can see, the SD is longer and the synchronization takes no real time (as befits a NFS share with active sync), and the whole process takes less than 10 seconds: this is four times faster!

  I don't see these results on data warehouses mounted via NFS.  For example, here is a test on the guest even running from a mounted via iSCSI data store (using the exact same SIN):

  As you can see, the performance of NFS direct comments for each of the three are very consistent.  ISCSI and the performance of the store local data disk are both a bit better than that - as I expect.  But the mounted via NFS data store gets only a fraction of the perfomance of the any of them.  Obviously, something is wrong.

  I was able to reproduce this effect with an Iomega Ix4 - 200 d as well.  The difference is not as dramatic, butalways important and consistent.  Here is a test of a guest of CentOS using a VMDK stored in a data store provided by an Ix4 - 200 d via NFS:-.

  Once more, the direct NFS mount gives very consistent results.  But using the diskette provided by ESXi on a mounted NFS datastore gives still worse results.  They are not as terrible as OpenFiler test results, but they are constantly between 60% and 100% longer.

  Why is this?  What I've read, NFS performace is supposed to be within a few percent of the iSCSI performance, and yet I see between 60% and 400% worse performance.  And this isn't a case of the SIN is not able to provide correct NFS performance.  When I connect to the NAS via NFS directly inside the guest, I see much better than when ESXi connects to the same NAS (the same proportion!) via NFS.

  The configuration of ESXi (network and network cards) is 100% stock.  There is no VLAN in place, etc., and ESXi system has only one

  Single Gigabit adapter.  It is certainly not optimal, but it doesn't seem to me to be able to explain why a virtualized guest is able to get a lot better performance NFS as ESXi itself to the same NAS.  After all, they both use the same exact suboptimal network configuration...

  Thank you very much for your help.  I would be grateful any idea or advice, you might be able to give me.

  Hi all

  It is very definitely a performance O_Sync problem. It is well known that NFS VMware shops still use O_Sync for writes little matter what share put for a default value. VMware uses a custom file locking system so you really can't compare it to a normal NFS share connection to a different NFS client.

  I have validated that the performance will be good if you have an SSD cache or storage target with enough reliable battery backup.

• ESXi 4.0 & incompatible network adapter

  I'm trying to install ESXi to see if it's something I want to use on your desktop new HP Z800 , which comes with 2 Broadcom NetXtreme Gigabit Ethernet network adapters. Here, I installed the other OS (Windows 7, Windows Server 2008), and two of them see network adapters, so I know that they are in good working condition.

  When I try to install ESXi, he goes through the process of decompression for a long time while it comes with a screen of text style 'BACK' base indicating "no compatible network adapter found. Please see the hardware compatibility Guide (HGC of the product) for the list of supported cards. "and won't let me go any further in the installation process.

  First why should place one network adapter for installation? Second, why is it something special because it seems to me (a type of material being not) that all network cards are basically the same today?

  I crossed and applied all the updates (BIOS, Chipset, etc.) to the material that I can apply and as I said works with at least two operating systems, so I don't know how to go beyond that.

  Clues?

  > First place why should one network adapter for installation?

  ESXi is managed from the remote computer, so ESXi without network card is unnecessary.

  > that all network cards are basically the same days now

  They are not.
