• What is the difference between codec primary and secondary codec in cts-3000?

  Hello

  I'm a novice on telepresence. This community is only a place to resolve issues for me.

  What is the difference between codec primary and secondary codec in cts-3000?

  I know the primary function of the codec. but I don't know exactly of secondary function of codec.

  Help me please.

  Hello

  On a CTS 3000 system, you have 1 codec primary and secondary 2 codecs. Secondary codecs are responsible for the camera left and right and view the connections. They communicate the main codec via an Ethernet cable.

  Here is a guide to the installation of a CTS-3000 so that you can see the routing of cables.

• No TCP between hosts, ping works fine

  I have ESXi installed on a Dell C524-TY with two NIC 5 and you have set up several Solaris 10 upgrade 10 physical hosts and VIRTUAL LAN interfaces. There are two Cisco switches between the NETWORK card with the installation of trunk between them and the server ports. The physical interfaces have connectivity through the switches VLAN 1, ssh, ping, etc. Interfaces VLANS are configured for VLAN 2000 and I cannot ping between them, no problem, but ssh or any kind of TCP connection just times out. I can also ping between installation interface VLAN (SVI) on the switches and telnet from one switch to another, and ping the virtual servers. When I run a snoop I see TCP request to arrive but they come from different IP addresses, which is attributed.

  On the receiving host:

• vMotion between hosts on different subnets

  Before you start, I'm a network engineer, not a server guru, please bare with me

  Is it possible to vMotion a virtual machine to a host on an IP network to another host, on a different IP network?

  Example:

  Data Center 1 - 10.1.1.1/24 with VM in the 10.1.2.0/24 ESX Server

  Same city, different site, binding fiber 10 GB between facilities 2ms latency

  Data Center 2 - 10.2.1.1/24 in the 10.2.2.0/24 with VM ESX Server

  Scenario:

  vMotion a computer virtual network 10.1.2.0/24 to the 10.2.2.0/24 network where virtual machine, on arrival on the ESX 2 data center server, now uses a IP address of 10.2.2.0/24.

  Any guidance towards a white paper or a guide would be greatly appreciated.

  Thank you all for your time.

  vMotion is possible between hosts on different subnets, but unless your discussions presented to the virtual machines are on the same subnet, you will eventually drop the virtual machine on a VLAN different and IP addressing will fail.

  There are ways around this, you could script the change of IP address / present several IP addresses of the virtual machine / or reservations DHCP to use, but you will need to ensure DNS etc. records are updated.

  If you have some kind of load balancer, you could in theory balance workloads on 2 IPs hosted on the same VM, to solve the network ip address issues, although in the end, you'll want a VLAN tended to port VM coverage groups.

  Good luck

• DMA between host and target FPGA is not supported for this remote system.

  I try to cover with my FPGA (on the cRIO-9002) of the RTO.  I have install upward of anOpen good VI reference without error, but as soon I try to access thefifo I error-63001 and the attached message wrote:

  Error-63001 occurredat reference FPGA VI opened in the target - multi rate - variables - fileIO_old.vi

  Possible reasons:

  NOR-RIO FPGACommunications framework: (Hex 0xFFFF09E7) DMA from the host to the FPGA targetis not supported for this remote system. Another method for controller of e/s or climatiqueLes associated with the FPGA target.

  What other I/O optionsdo I need to move the data asynchronously to the RTO for the FPGA. I have triedcreating memory, but it seems that I can't write to the memory of the RTOSside.

  We have also a 9012sitting around will using this cRIO rather solve this problem.

  I'm very very greenwhen it comes to LabView, so I apologize if this is an easy question.

  As stated in the readme of the driver NOR-RIO, DMA is not taken in charge from the host to the FPGA on the cRIO-900 x series. The cRIO-901 x supports DMA transfers between host and FPGA and FPGA to host all the cRIO-900 x series controllers only support transfers the FPGA host DMA. As a result, LabVIEW returns an error if you try to transfer using DMA controller for cRIO-900 x.

  The 9012 looks like the ideal solution, you are very lucky to have additional hardware laying around

• Cannot drag-and - drop between host and guest

  12 workstation

  Host = 10 Pro x 64 Windows

  Comments = 10 Pro x 64 Windows

  Everything is entirely up to date, etc. on a Z87 PC chipset.

  I can copy and paste. I can drag-and - drop comments to the host.

  I can't drag-and - drop between host and guest! lol I just get that bar circle icon.

  I'm totally stumped! I tried a myriad of common things...uninstalled/reinstalled VMWARE, then Tools, then even tried to create new guests. I do not have eccentric tweaks or customizations. It is a desktop PC that I use for a laboratory test and my business. I have no other problems in addition to this. Yet, on my other system, essentially a nearly identical configuration, I don't have this problem.

  Any suggestions?

  SOLUTION FOUND!

  The problem boils down to a matter of RUN AS ADMIN. On the HOST problem, it has been set to RUN as administrator. I've not done this! He has just installed that way automatically. Once I stopped that and it ran normally, all was well again. Read below for more details.

  I have two virtual HOST machine configurations almost identical - we'll we'll call HOST 1 and HOST 2. HOST 2 works perfectly without a problem. Drag and drop, to navigate to drives mapped to access NAS stored VMs, etc...

  I began to compare what was similar vs. different between the two. On HOST 1 (problem child even as I could slide properly - drop on), I noticed that I could not navigate to my NAS location where some virtual machines are stored. In the left navigation panel, the mapped drives would appear as drive letters with question marks next to them as you can see in the image below.

  

  I deleted the mapped drives then mapped them still fresh, did an other CLEAN uninstall VMWARE WS PRO 12. I combed the registry, records and checked for devices hidden in Device Manager. Clean as a whistle! I reinstalled 12 Workstation and returned the problem! I could yet drag-and - drop properly or navigate to mapped drives. Then I noticed the HOST 2 that he was not being RUN as administrator. Really? So, I removed this parameter and TA DA! Everything started to work properly. I don't know if it's a bug, or knowledge common to others but for me it was new. I don't know why, by default, when installing 1 HOST went down VMWARE to run as administrator, but it was.

  Bottom line - do not run VMWARE as an administrator.

• VMWare Server 2 - Pb communication between hosts

  Hi all.

  I just install VMWare Server 2 on my laptop to perform tests. I read 4 virtual machines but to my surprise none of them ping the other. My Vms do not communicate with each other.

  The 'network' main pour 4 virtual machines is 'host only '.

  Is what someone would have an answer to LUN pb communication?

  Thank you for your answers fast.

  -host only: allows the VM to communicate only with the host (the one that contains the VM).

  -Bridge: allows the VM use the physical host computer card, as if it were a network bridge. This allows to use the VM on the same subnet as the MPhy. The MPhy and VMS can to communicate without problem as if there was only some MPhy on the same subnet.

  -NAT: it's the year translation system.
  This means that the VM will not be on the same sub network as the LAN MPhy.
  And the of the VM in a single @IP of the side physical LAN of the transforms the @IP of the gateway NAT (principle used when you have several computers connected to a * Box ADSL which has only a single Internet @IP).

  I think you Pourrat find the answer yourself.

• Can I create an internal network or isolated on VDS shared between hosts?

  We seek to deploy VDS on our site of recovery (for MRS). We have expanded network of level 2 so the primary site and recovery, guests can use the same IP addresses, but I don't know the best way to test the SRM. If I create a dvportgroup SRM, without a dvuplink, the dvportgroup may exist on all hosts that share the same configuration of VDS, but will be virtual machines connected to this dvportgroup be able to communicate on different hosts?

  Otherwise, what is a good way to achieve an isolated private network that can be shared between virtual machines that have the same IP address as production systems? A distinct community VLAN?

  They will not be able to communicate without a VLAN on the physical switch upstream.

  If you have licenses VCloud suite for POSSIBLE, you could create a VXLAN to communicate, but the easiest solution would be to create a VIRTUAL LAN.

• 515E - host on VLAN may not leave

  Hi all

  I have a restricted license, the PIX 515E 6.3 (4) running. 2 physical and logical interfaces 1 (Vlan20). The movement of the inside to the outside and inside to Vlan20 works very well. Set up a domestic test Web on Vlan20 and can host server access without any problem. HOWEVER! Hosts on Vlan20 cannot send or receive through the outside interface! I'm dying here...

  The only other thing I can think is the possiblilty that, since you are not using a NAT at the address which is routed through your router upstream to is you have a routing problem there. If your upstream neighbor does not route these addresses to your pix that COULD be your problem. You could try the pat to see if it solves your problem and which would indicate that there is a routing problem.

• Can't access ESXi host after VLAN for MGMT has been implemented?

  Hello

  We run ESXi 5.1 and recently to get our network

  Network administrator has received only 5 VLAN for MGMT vSwitch.  Since then, we are not able to ping on the ESXi host, or access in vCenter.

  He received different VLAN for vMotion and vSwitch and VM.

  Just would like to ask your advice what changes I need to do?

  Hello

  That doesn't sound right. You have 3 different vSwitches with 2 ports on each, so you can not the team together on the side of the switch.

  This would have been right if you had a vDS with 6 uplinks and various exchanges by the feature that you do not.

  You have need of the network is to set up 3 different teams one by vSwitch and to start with that you have the management must be in the access mode so that you can retrieve with your ESX box connectivity.

  Also the vMotion didn't need to be mode trunk you'll only of vMotion. Data (VM) must be master.

• Private network between hosts in different regions

  Dear guys,

  I have just asked me if it would be possible that 2 hosts in different regions (EU-NA) can communicate on a virtual private network over the Wan.

  How to perform I thought to arrive at:

  -import the host NA in a cluster in the EU vcenter

  -create a tmp DVS and attach 2 guests to the DVS

  -create a private VLAN GP and configure 2 virtual machines with this PG = > they just have to communicate with each other, this is just a test

  The question I have is this: given that the 2 hosts are in different regions, traffic of 2 VMs would go across the WAN using the DVS even?

  Thanks in advance.

  Daniele

  I thought on it and it is not possible, DVS and a dummy network, we have L2 and we have no tools for the encapsulation of L2 to L3, I have no NSX.

  I will give points me

• vMotion between hosts 4 ESXi and ESXi 5

  I have a group of ESXi 4.x hosts connected to a vCenter Server 4.1.  I have an another 5.1 vCenter Server Management 5.1 hosts.  I want to move my hosts ESXi 4.1 in my 5.1 vCenter Server and upgrade to 5.1.

  Since vCenter 5.1 can manage ESXi 4.x and 5.1 hosts in the same cluster (KB VMware: upgrading vCenter Server 5.1 recommended)

  Could I add my 4.x hosts to vCenter 5.1 and put them in maintenance mode one by one and then upgrade?  I'd be able to vmotion the VMs between my 4.x and ESXi hosts 5.1?

  The goal is to reduce or hopefully elimate downtime for virtual machines.

  Thank you!

  You can get the upgrade with no interruption of service, if you can:

  (a) connect the storage 4.1 hosts FC 5.1 guests, so it is shared by all hosts

  or

  (b) your license allows you to storage vMotion the VMS to storage of 5.1 hosts

  The normal steps would be:

  -Disconnect the 4.1 hosts the vCenter 4.1

  -Connect the 5.1 vCenter

  -connect storage 4.1 for the 5.1 hosts or Storage vMotion the VMs on

  -vMotion the VMs to 5.1 hosts

  -upgrade the 4.1 hosts

  Concerning

• Can we do vmotion between hosts with load balancing in network cards grouping different strategy.

  Hello

  We are implementin new host in our Infra and do some vmotions between different groups. A group a host with balancing 'route based on IP hash. " Can we do Vmotion to another cluster where the hosts have different load balancing policies. In addition, if we change the policy on new hosts in furture of load balancing is loss of downtime or a package?

  Kind regards

  Vikram Kumar

  First of all, no problem from VMs one ESX to another, they use different political Multipathing.

  Second, if you use IP hash, it means you are using etherchannel (or LACP) on the physical layer - configuration/cancellation of the configuration that almost always require that the uplinks are not used by any VMs, so you have time to synchronize the physical and virtual configuration. It is not a time out, but you need to plan accordingly - all depends on your physical network capacity.

• Share LUNS between hosts ESX4 and ESX3.5

  Can I share a unit logic between an ESX4 and a crowd ESX3.5 number?  Not wanting to vMotion or HA or anything like that, just to share the same LUN.  Didn't the VMFS differences between them.

  Yes, you can. Just do Datastore on 3.5 host LUN to be sure.
