• Reference Dell MD3200i correct editing with IP system and the NIC for faster network speeds

  Hi all

  I worked on this project for a while now. I did a lot of research and have contacted Dell several times. I need help.

  I have 2 sets of identical to use for Hyper-V clusters servers. We bought a Dell MD3200i in November, we also bought a Dell 5424 switch and a Cisco SLM2048 switch. These servers have Real Tek 2 network cards for iSCSI Jumbo frames is 9 k

  The Dell MD3200i is two SAN controllers. Dell 5424 is the iSCSI optimized switch and Cisco is a 48 switch ports. iSCSI is on its own network that nothing else is connected to it. (There is an Iomega NAS and a promise Vtrak SAN Tech with all current domain of execution with iSCSI controller)

  Reference Dell MD3200i controller 0 Port 0 192.168.130.101 controller 1 Port 0 192.168.131.101

  Controller controller Port 1 0 192.168.130.102 1 1 192.168.131.102

  Controller controller Port 3 0 192.168.130.103 1-3 192.168.131.104

  Cisco switch has 1 VLAN n ° 1 on it and the 130 subnet inside elements. There are 8 connections to the switch. 4 controller 0 and 1 of each of the servers. It has an IP of 192.168.132.4, but that switch IP does not make difference. Lighted Jumbo frames

  Dell switch has 2 of #1 for various things such as the domain controller, Vtrack, and SIN. Subnet 2 is 131 and has a total of 8 connectors inside. 4 in 1 controller and 1 from each of the servers. Lighted Jumbo frames. The switch IP address is 192.168.132.2

  Groups of servers. Each server node running Windows 2008 R2 SP1 and running hyper-v with virtual server clusters / storage folder on them. 2 Realtek NIC with Jumbo frames made 9 k ProdNode1 and ProdNode2 have 12 Core i7 CPU with 12 GB memory, EXNode1 and ExNode2 have 12 Core i7 CPU with 24 GB of memory.

  ProdNode2 iSCSI-1 192.168.130.120 ProdNode2 iSCSI-2 192.168.131.120

  ExNode2 iSCSI-1 192.168.130.140 ExNode2 iSCSI-2 192.168.131.140

  Portal discovery iSCSI on ProdNode1 went to 192.168.130.110 192.168.130.101 and 192.168.131.110 192.168.131.101 each of the other servers Discovery Portal have been pairs like this.

  iSCSI tab click on add 8 MPIO sessions at each of the ports on the MD3200i from Dell, target. For example, I added 1 session of 192.168.130.101 using it. Add Session,--> activate--> Advanced Mutlipath--> Local--> IP 192.168.130.110 initiator and target 192.168.131.101 iSCSI adapter. This is repeated on all servers. 4 connections for each NIC.

  The network is very slow. It revolved around 2 to 4 MB/MIN and it should be much faster. Initially, we had only the Cisco switch with only 1 VLAN and everything connected directly to it. I read somewhere that MPIO has been the problem, so I went through the same configuration but does not verify the MPIO checkbox above. Once this has been done, the network speed went up to 1.5 GB/Min but modular storage Dell was not happy, and virtual servers would fail and the connection is not very stable.

  What wrong with my setup? Can I directly home and fix the servers directly to the PowerVault and will make stable and allow for failover and redundancy NIC? I need to get this stable so I can move with something else.

• UCS C200 and NIC Teaming/FailOver

  As UCS C200 with management of a 10/100 and 10/100/two interface 1000 interfaces and PCIe with 4NIC

  I want to install CUCM 8.5 is the NIC Teaming/failover supported by UCS C200 and how to set up the NIC Managment interface with failover?

  Thank you.

  Hello

  As you install apps from the CPU on the server of the UCS, speech application team listed their recommendations here.

  http://docwiki.Cisco.com/wiki/QoS_Design_Considerations_for_Virtual_UC_with_UCS#Guidelines_for_Physical_LAN_Links.2C_Trunking_and_Traffic_Sizing

  You can create a NIC teaming in the ESXi via vSphere client software for traffic from from / destined for virtual machines.

  For C200, we have only one management port and if you use the management for MMIC traffic port, switch option is not available.

  However, if you choose to use host for MMIC traffic NETWORK ports, you can set up CIMC NIC mode for 'LOM shared' which provides the NIC teaming options.

• ISE Cisco 3395 NIC Teaming/redundancy

  Is it possible to implement the consolidation of NETWORK cards on a 3395, I see that it is available on the SNS 3400 series? However, I was unable to locate any information about NIC grouping for purposes of redundancy on of the 3395. This feature is taken in charge, and if so, how I would approach him allowing of correctly? Thank you very much for the help in advance.

  Hello. For now, ISE does not support the NIC teaming/pipe of any kind. It asked that several times so I hope that Cisco will implement in a future version.

  Thank you for evaluating useful messages!

• NIC teaming and aggregation rate

  Hello

  I need help on configuring NIC teaming on our ESX. We have a HP Server with 6 network adapters I already configured the vSwitch for VMkernal, VMotion and Service Console.

  Now, since the ESX will run at various Web servers I want to do is aggregate throughput of EPS of 1 GB to give me a flow of 4 GB total. What I've done is created a vSwitch and alllocated 4 NICs to the switch and created a port called 'Prod LAN' and receives the NIC 4, also on our Cisco switch I trunked 4 ports.

  What else do I need to do to make sure that I have configured correctly the NICs, so that when we assign the network adapters on the virtual Web server computer it can use aggregate 4 GB throughput. Also that I also want to make sure, if some fail NIC 1,2 or 3, I always have speed on the port.

  Thank you very much...

  Duncan has identified the problem above with what you are proposing.  You may agree with your config if a physical switch entire fails but as stated above, if you lose an single link on one of the aggregates that ESX will add a unique link from the passive cluster causing the switch to become crazy.

• What is the different NIC Teaming policy between vSwitch properties setting and Port-Group

  Hello

  I know that there r two ways to set NIC Teaming policy: vSwtich or Port Group.  What is the different?

  Who is the highest priority?    Could the port group properties overrides the setting of vSwtich? Or just inherit.

• Are these viable designs for NIC teaming on UCS C-Series?

  Is this a viable design on ESXi 5.1 on UCS C240 with 2 Quad port nic cards?

  Option A) VMware consolidation of NIC with the load balancing of interfaces vmnic in an configuration active/active through alternate and redundant physical paths to the network.

  Option B) VMware consolidation of NIC with the load balancing of the interfaces in a configuration vmnic Active/Standy by alternate and redundant paths of material to the network.

  Option A:

  

  Option B:

  

  Thank you.

  She really comes down to what means active/active N ° and type of switches upstream.  For ESXi NIC teaming - Active/Active load balancing provided the opportunity for all network links be active for devices different comments.  Grouping can be configured in a few different methods.  The default value is by ID of virtual port where each guest computer is assigned to an active port and then also a spare port.  Traffic to this host would be only sent on a connection at a time.

  For example, suppose 2 Ethernet connections and 4 guests on the ESX host.  Link 1 for switch 1 would be active for 1 and 2 and 2 link to switch 2 backup for 1 and 2.  However 2 link to switch 2 would be active for 3 guests and 4 and 1 link 1 switch backup for 1 and 2 comments.

  The following provides details on the configuration of the card NETWORK is teaming up with VMWare:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=1004088

  There are also opportunities for LACP configuration in some situations, but there is a material special considerations on the side of the switch, but also on the host side.

  Keep in mind that the vSwitch does not blindly broadcast/multicast/unknown unicast on all ports.  He has a strict set of rules that prevents loopback.  It is not a traditional L2 redirector so loops are not taken into account in an active/active environment.

• iSCSI / vmkernel multipathing vs NIC teaming

  Hello

  I know of Configuration of VMware SAN Guide provides information about how to configure iSCSI multipath with vmkernel interfaces double on various uplinks.

  What are the disadvantages of using basic NIC teaming instead? Just an interface of vmkernel on a vswitch (d) with two uplinks. It will work properly about redundancy and failover?

  Kind regards

  I guess the difference is while using "Port Binding" iSCSI initiator uses vSphere Pluggable Storage Architecture to handle the load balancing/redundancy, that can make better use of multiple paths to NETWORK card available. Otherwise, the initiator will use vmkernel stack ensures redundancy network and balancing in the same way as a normal network traffic.

  I suggest that you look at the great post on iSCSI multi-vendor, I think the 2 statements below will summarize the difference:

  "

  • However, the biggest gain of performance allows the storage system to scale the number of network adapters available on the system. The idea is that multiple paths to the storage system can make better use multiple paths, he has at his disposal than the consolidation of NETWORK cards on the network layer.
  • If each physical NETWORK adapter on the system looks like a port to a path to the storage, the storage path selection policies can make best use of them.

• NIC teaming on HP Blade

  I use HP Blades as my servers to host ESX 3.5 update 3. I have only 2 NETWORK ports on each host and I would like to implement the NIC teaming, but I'm confused on whether I would run into any problems if the vmnic should fail.

  I set up vswtich0 with three groups of ports - the primary NETWORK card for my Console Service (VLAN12) and port groups Vmotion (VLAN3) is vmnic0 with vmnic1 failover

  I also created another group of ports for the VMservers vmnetwork (no VLANs) on vswitch0 with vmnic1 as a principal port with vmnic0 my failover group.

  What concerns me, is the port group settings switch to vmnic1? For example, if vmnic0 tilt vmnic1, will I run into issues because the Service Console is running on VLAN12 and Vmotion works on VLAN3, and vice versa with the port vmnetwork group.

  Hello

  You will need to implement VST where you master all the VLAN to the vSwitch through each Teddy.

• Configuration of several interfaces vlan on a layer 3 switch

  I am trying to incorporate a layer 3 switch in a network. (see figure 1 below). My problem is that in the configuration below, the layer 3 switch seems to offer no additional benefit on a layer 2 switch, because it does not pass packets from Layer 3, instead, it will take an additional router configuration.

  If I set up 2 interfaces like no switchports (diagram2) and create virtual interfaces on the switch of level 3, that is to say 0.1/g0, g0/0.2, 0.3/g0, g0/1.1,g0/1.2, g0/1.3, configure dot1q encapsulation and add ip addresses and subnets on each interface, so I understand that I can use the switch of level 3 as a router.

  However this introduces a new problem now, VLAN 1 is on both interfaces, so devices in VLAN 1 on each interface will have point to the default gateway on this specific interface and features of VLAN 1 on G0/0.1 interface must be configured with a different subnet than those on G0/1.1 interface.

  It does not seem logical, am I missing something?

  On a L3 switch you do not configure subinterfaces (usually).

  You create what's called Lass (Switched Virtual Interfaces) instead of this, and what are your L3 interfaces.

  If your L3 switch ports are ports of L2 or other trunks or assigned to a VLAN specific.

  For each VLAN you want to route you create then a SVI IE. -

  int vlan
  IP x.x.x.x
  No tap

  and the default gateway for clients in this vlan is the IP assigned to the SVI.

  Any other configuration of L3 interface, you add to the SVI.

  The only time wherever you actually use the ports of L3 is when you connect to a router for example.

• Is it possible to superimpose a 3cr17161-91 3Com with another Cisco layer 3 switch?

  Hello

  Nice day.  I would like to ask whether it is possible to superimpose a 3cr17161-91 3Com to a layer 3 Switch Cisco? The two will be stacked using the SFP modules available to the general public.

  Thank you

  Hi Rey, not with switches for small businesses. Small business past stack with their own range of products running the same software. Something like SGE2010 won't stack with SG500-48 as example.

• NIC teaming with the IP hash load balancing

  Hi guys

  I have a virtual machine with a VMXNET3 10 Gbps. It is usually have a heavy traffic with a special server and saturate one of my two physical NIC of 1 Gbps in its PortGroup. I want to know what's going to happen if I turn on "NIC Teaming for this portgroup with basic IP hash load balancing". In my case the source IP address and destination are not change so the aggregates of traffic between my two physical network adapters?

  To avoid saturating completely the two 1GbE NIC, it can also be useful to look in charge based on the grouping and the NIOC. It will ensure that the other streams of traffic VM are not crushed by this machine a virtual when it saturates a network card. The disadvantage is that it requires Enterprise Plus licenses (using a dvSwitch).
