• vCenter 5.5 install - physical vs virtual

  We are relying on companies more edition and we have about 600 guests esxi and 5000 vms and 50 clusters. Currently we are trying to ruin vCenter 5.1 in a virtual machine (cluster-HA/DRS) with stand alone DB SQL backend running on separate virtual computer. We intend to migrate VSS to DVSs and take advantage of the other features of more editing. VM still good for vCenter 5.5, if yes, what is the resources max and other configurations, I need to consider for vCenter deployment in a virtual machine? Appreciate your help

  Thank you

  There is no difference in the maximum rates of configuration runs vCenter virtual or physical, at least if current running on the virtual computer, you have to play close attention to certain best practices. Have a look here: recommended: running virtual vCenter (vSphere) - yellow brick

• vCenter:-change from physical to virtual

  Hello

  I have 1 Server vCenter 5.0 which is a physical machine.

  Physical machine (vCenter Configurations):

  1 HP Porliant Server

  2. Windows Server 2008 R2 STD SP1.

  3 RAM: 16 GB

  4 CPU: Interl Xeon 8 cpu.

  I want to have my server vCenter as a virtual server rather than physical.

  Can I create a new virtual machine and install vCenter 5.0 on it, and then point it to the existing database (SQL 2008 R2 - Cluster)?

  OR

  I have to create a new database as well and restore the existing DB Backup, then point vCenter for her?

  OR

  P2V using vCenter Converter my only option?

  Also anyway, I only add hosts to vCenter after its VM on as they will appear disconnected. Right? Something else is needed?

  Thanks - AG

  Yes that is correct:

  Create the system DSN proper connections on the new host to vCenter server. For more information, seedisplaying and editing of the database server to vCenter Server installation fails with ODBC and DSN errors (1003928).

• Physical to virtual (P v) Conversion of vCenter Server

  What are all the things I need to think about when convering vCenter server from one physical machine to a virtual machine?  For example:

  1 if the SQL database is on the same server, it can be corruputed?

  2. If I create P to V would be vm and let it sit for a day, while the physical vCenter server is in place, what is happening with Active Directory when I stop the physical and virtual vCenter server takes over?  The vCenter Server virtual would have a less recent synchronization with Active Directory than the physical server, I just stopped.  No problem?

  StageCoach says:

  No unjoining and join vCenter server to this domain questions all possible - such as the loss of permissions, etc that I need to be wary of?

  nothing whatsoever.  vCenter has all it's information stored in a database.  The reason for the possible reach of the field is just to update the AD and DNS object

• 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.

• Advantages and disadvantages of the use of the same network card to the network management and production (all my virtual machines) VLAN?

  Hello

  I have an ESXi. The management network and the virtual machines vlan through the same network adapter.

  What the disadvantages are to do?

  Can you help me please?

  Thank you in advance,

  Kind regards

  Garish

  Well well, in this case. This is a perfect case of SPOF, try to reach NIC teaming to avoid this.

  At least two cards physical network is necessary in your hardware ESXi host to do.

  Download an official guide of VMware Networking from the following URL, it has got everything you need and much more.

• Is storage adpater for Vcenter, necessary?

  Stupid question, but if you have Vcenter Server on one physical server, it needs to have access to your storage network?

  I did have to make an installation in a while so sorry if this question is stupid.

  I have a customer who ordered 3 new servers and a storage array Fibre.  2 servers will be used for ESXi and the other server is a server main lower they were planning to use for Vcenter server.  They have a fiber switch and each server ESXi came with fiber cards.

  However, the server vCenter came not with a fiber card.  Need a fiber card?

  Or he does not she and Vcenter gets all the information storage of ESXi hosts?

  Thank you

  Mike

  If there is no special reason to have vCenter Server running on dedicated hardware, I agree with golddiggie to define as a virtual machine and save money for the server.

  Subject of your question:

  However, the server vCenter came not with a fiber card. Need a fiber card?

  No, there is absolutely no need for the vCenter Server to access the storage. He only manages the ESX(I) hosts on the network.

• With the help of Vlan for LAN and DMZ

  Hello

  For the moment, I have assigned my LAN and DMZ networks to two separate network card (so therefore no Vlan tagging)

  for example vmnic0 = LAN, vmnic1 = DMZ.

  It works well but I like to make changes in the way I want to use two separate physical network adapter and use on the two s two LAN and DMZ nic but now using the VLAN.

  So think of this configuration:

  For each network, I create a Vswitch, in order to obtain a Vswitch named VsLAN, VsDMZ for the case.

  The Vswitch I attribute a two nic Nic will be the day before. as vmnic0, vmnic2 (at rest)

  This Vswitch I create a port group and assign the correct number of VLan as LAN 10 and 20 to the DMZ.

  Create the another Vswitch will have the same Nic but now vmnic0 will be the stanby one.

  Probalby all great so far I think or not?

  Issues related to the:

  -Well this concept where there is a relationship a Vswitch and port group or a switch with multiple exchanges?

  In case a Vswitch with multiple port groups I will assign to group level reserve and the active NIC Port.

  -If I create a group of ports and assiging several Vlan IP packets received by the virtual machine itself also be labelled or not identified?

  Other words. Do I need to configure the NETWORK adapter to the virtual machine also for the same local network ID virtual or not.

  Thanks for your comments.

  Hello

  Change of vlan is a pretty good idea to get the failover and the performance of the network LAN and DMZ. You have confused somewhat however concepts.

  A can only be used in a vSwitch vmnic. So what you want to do is the following:

  Create a vSwitch

  On the vSwitch create two ports: LAN (vlan10), DMZ (vlan20)

  If vmnic0 and vmnic1 have access to the vlan10 and 20, then simply add the two vmnic virtual switch. By default, they will both be active and that's fine. If you do not want to CHANGE the GRPE ports LAN and goto the "failover" tab and put vmnic0 as active and vmnic1 as before. Then do the reverse on the DMZ port group.

• Is a new virtual Center required for deployment of Horizon view 6 / licensing issues

  Hey all,.

  Just curious to know if it is required or existing best practice to install a separate virtual Center for your environment from view of the Horizon, or if it is correct to attach it in your VC.

  Also, reading that I've done, it seems that when you buy Horizon display 6 advances you get ESXi licenses as well?  Is it true.

  When it comes to the Windows 7 license you ave h to buy anything for your VDI VMware or do you just an open license / SA with Microsoft for Windows 7/8

  I think the projections and business decisions will do that for you.   Some circles have separate teams who manage desktop and server infrastructure.  In these scenarios, you can have a dedicated instance for VDI and the office team.     In other environments, you can be a small shop where a couple of technicians do everything.   In this environment, it can be allowed to have a single vCenter.     I still hate the TI depends on the answers, but in this case it really depends on your environment and how you want to manage.

  2: based on the comparison on the site, all the editions come with vSphere and vCenter for desktop.    I read you right, but I would check with a specialist VMware licenses.

  3: Just that you have the licenses required in view and vSphere VMware wants.  They do not all control over your Microsoft licenses.

• Configuration of SQL 2008 R2, Enterprise Edition for vCenter Server 5.1

  Greetings to all seasons.

  Kind of a newbie here. That's my lab environment.

  I have always used the vCenter Server install Simple option that also installs the shipped Microsoft SQL 2008 R2 Express edition.

  Now, I do an eval of vSphere 5.1 and I want to manually configure a database server using the Microsoft SQL 2008 R2 Enterprise Edition.

  I know how to install the database server and it works. But I do not know how exactly set up a database for vCenter Server.

  I looked at the guide Configuration / Installation of vSphere and I don't seem to be able to follow the preparation vCenter Server databases section, because I'm not a person to the database. Y at - it any other guide or a blog, I can follow? I searched a lot and found everything I was looking for. Thought I would ask here.

  Here are the virtual machines I have.

  Lab - DC1 (domain controller)

  Lab - DC2 (domain controller)

  Lab-SQL1 (SQL 2008 R2, Enterprise Edition)

  Lab-SQL2 (SQL 2008 R2 Enterprise - subsequently configure failover clustering)

  Lab-VC1(vCenter Server 1)

  Any help is appreciated!

  Happy holidays.  Here is a link to another site with a nice installation guide for SQL 2008 for VMware.  Version 4.x, published in lonesysadmin.net was very helpful, so I'm sure that the 5.x update (have not read through it again) must be all too packed with useful tips.

• RDM (Raw Device mapping) physical or virtual?

  Hello:

  I have VM and will add a hard drive.  RDM will be, but I was wondering what "Compatibility Mode" choose "physical or virtual?

  It's my production Oracle machine and this new drive will contains about 500 GB of DATA...

  I think it would be nice to use the 'virtual' mode, to make snapshots, but I'm worrying that, for this one big disk, it will take a lot of time and a lot of space... There are other arguments that I should consider?

  Thank you very much.

  "design of the SAN and Deployment Guide system.

  Virtual mode for a mapping specifies full virtualization of the mapped device. He

  appears to the operating system exactly the same as a virtual disk in a file

  VMFS volume. The actual physical features are hidden. Virtual mode

  customers who use raw disks of the benefits of VMFS, such as advanced files

  locking for snapshots to streamline development and data protection processes.

  Virtual mode is also more portable across storage than the physical hardware,

  with the same behavior as a virtual disk file.

  Physical mode for a device mapping gross specifies the SCSI virtualization minimum of la

  device mapped, allowing greater flexibility for SAN management software. In

  physical, VMkernel mode all SCSI commands to the device, with a

  exception: the REPORT LUNS command is virtualized, so that VMkernel can isolate the

  volume to the virtual machine owner. Otherwise, all the physical characteristics of the

  underlying hardware are exposed. Physical mode is useful for running the SAN management

  agents or other software SCSI target on the virtual machine. Mode of physics

  also virtual and physical memory allows for cost-effective high availability clustering.

• Transfer multicast through VLANs for KVM Over Ip

  I am currently designing an architecture of Terminal servers, using the KVM-Over-IP technology (I use features of Gefen) where I have two VLAN:

  • A VLAN for screens (receivers KVM) at 192.168.240.0/24
  • A VLAN for servers (KVM shippers) to 192.168.241.0/24

  I use a Switch Cisco 3750 G Layer 3. I have configured all the VLAN with their gateways (. 1) and there is connectivity between devices, so this ping between them, etc. The configuration is as follows (this is an excerpt, the rest are the default values)

  IP routing
  IP multicast-routing distributed
  !

  GigabitEthernet1/0/1 interface
  switchport access vlan 2
  !
  interface GigabitEthernet1/0/2
  switchport access vlan 10
  !
  interface Vlan2
  IP 192.168.240.1 255.255.255.0
  IP pim sparse - dense mode
  !
  interface Vlan10
  IP address 192.168.241.1 255.255.255.0
  IP pim sparse - dense mode
  !

  Now, KVM (these devices Gefen DVI KVM) devices cannot auto detect other KVM devices in different VLANS. It is to be expected, because the broadcast messages do not exceed the limits VLAN. After further investigation, looks like these devices use multicast groups to annonunce themselves, using standard TCP connections later to perform the video transmission.

  To solve the problem, I enabled routing multicast distributed and also tried activation sparse dense mode. Using wireshark with duplication of port I see some messages of the devices within a local network VIRTUAL membership report and Protocol PIM from the interface messages VLAN (. 1), but the devices fail to see each other again.

  Thus, from scratch, how should I configure the 3750G for multicast traffic is shared between the VLANS? I also checked the MVR nothing helps.

  Thanks in advance.

  Just a thought.

  What is the Group of multicast discovery? If 224.0.0.x. that is not specific to the local LAN segment with a TTL of 1. In these cases the multicast routing road it.

  If it's another group of multicast, always check the LIFE expectancy in the packages. It can always be 1.

• Maximum virtual interfaces (VLANS) FWSM latest version

  Hello

  Please someone (perhaps cisco) can tell me for the FWSM for the latest 3.x version that corresponds to the maximum number of virtual interfaces (VLANS)?

  Best regards.

  It depends on the firewall mode, but I think that most of the time, the limit of vlan is related to the routed mode.

  Refer to this VLAN 3.1 FWSM features/limit:

• How to allocate disk space for vCenter server logs

  Hello

  I plan to level 4.1 to 5.5 U2d vCenter on the customer site. One of the conditions set out in the vSphere upgrade guide is:

  "In vCenter Server 5.x, the default size for vCenter Server connects is larger than in vCenter Server 4.x. make sure that the disk space allocated for the log folder is sufficient for this increase 450MB."

  My question is how to allocate disk space for the log file and where can I find the disk space allotted to file papers to vCenter 4.1 existing?

  Just see the free space on the partition where the vCenter server logs are stored. If it is insufficient, increase the size of the virtual disk and then increase the file system to the guest OS.
