where and how much Vcenter must be installed? as a virtual machine or physical host? -config is 2xESXi40 - CX4 - 120 1xEMC2 - DAS mode

"BEST PRACTICE RECOMMENDATION.

I work with 1 ESXi40 in DAS mode very good and everything is fine.

I have still a few servers production of Phisical aditional to be virtualized, but before that

We cultivate our virtual infrastructure by adding a second Esxi40 and installing the Virtual Center software and license to use HA, Vmotion, etc..

the questions and the thing is, if I'm migrating all my hosts physic to the VMs system, do I need a new physical server to install Virtual Center, yes or no.

and why?

If this is not the case, the Vcenter can be virtualized, and what is the best practice to do this.

which of the following configuration might be valid, the best recommendation and why and why not.

(a) create 1 Vcenter VM, located in a data store on the hard drive that comes a host of Esxi40

(b) create 1 Vcenter VM, created storage located in a data store that comes from the CX4-120, and the group contains 1 ESXi40 physical host

(c) create 1 Vcenter VM, created storage located in a data store that comes from the CX4-120, and the group contains 2 ESXi40 physical hosts

(d) create 2 Vcenter VW, created storage located in a data store that comes from the CX4-120, and the group contains 1 ESXi40 physical host

(c) create 2 Vcenter VM, located in a data store that comes from the CX4 - 120, ahd, the storage group created containds 2 ESXi40 physical hosts

Thank you

MC.

You're too complicate things...

Do the vCenter as a virtual machine, which gives the requirements for processors, RAM, etc... Place it on a data store available to BOTH hosts. In fact, I would make sure that ALL s LUN where sit all VM are available for BOTH ESXi servers.

I recommend also using a full SQL Server for the db, is not using SQL Express. If you have a SQL 2005 server, use it. If you want to future proof, vCenter things, put on a 64 bit OS (so you're ready for vCenter 4.1 and ESXi 4.1). Having the SQL database on a real SQL Server (other than the server vCenter Server/VM) makes things a lot easier on the road...

  • vCenter Server 5 install in a virtual machine or not?

    Hi all.

    We have a health care environment small assisted living with a dozen sites/servers

    A server has 3 VMw4 vms on it.

    We received two new servers ESXi installed 5. They will host several virtual machines of Windows Server for most of the migration of the current VMw4.

    I want to install vCenter Server 5 to manage.

    My book of VMware by Lowe, he mentions that install the vCenter server in a virtual machine has limits.

    It mentions cold migration, cloning and editing material are not available.

    He also mentions the considerations with the help of a distributed virtual switch.

    Ufortunately that he won't go into details.

    But there seems to be benefits such as the backup server and fast food when you use a virtual machine.

    Any thoughts?

    Thanks in advance.

    Hello

    It is one of the common design decision. now VMware recommended is to use a virtual machine.

    some of the benefits you can get are: -.

    The vCenter Server system can be revived in a cluster of high availability of vSphere

    VM resources CPU and memory can be easily resized. The vCenter Server system also benefits from vSphere Distributed Resource Scheduler (DRS) cluster workload balancing.

    You can easily save or create a virtual machine as needed.

    him as a physical Machine will be some disadvantages such as:-

    To ensure availability, you must purchase and use additional software such as vCenter Server Heartbeat or a third-party clustering solution.

    You must properly size the physical machine's resources.

    You must have a separate system and use imaging software to take a snapshot of a physical machine.

  • Host of XP with 4 GB of Ram - how much memeory can I connect to all virtual machines?

    I am running 2 VM (XP Pro - 32-bit)) on the XP Pro - 32-bit host (running Server 2.0).  I know there is a restriction on the host computer using only 3 GB of it, but I was wondering if the virtual machines have this limitation.  Example - if I assign 1.5 GB for each of 2 virtual machines, that is to say 3 GB used my VM 2 - will be the other 1 GB can be used by the host?  Alternativle, could I run 3 VM each with 1 GB and then the host would use the 1 GB remaining?  Or anything running on the system limited to 3 GB?

    I noticed when creating VM will occur, he says that I can attribute something like 4096MB before the exchange of memory?  Seems weird to me.  Any info on how memory is managed is useful!  I am not concerned about performance problems... I understand the limitation of the who simply want to understand whether or not the last 1 GB of ram is even used.  Thank you!

    in fact, you don't have to worry about this

    the VM process will be spread in all of your CPU/cores/HT etc.

  • How can access us the Client on a virtual machine on the host ESXi VI?

    Good afternoon, we are evaluating a virtualization solution, our company is small and we want only 3 servers to virtualize, and we want to use one of the virtual machines on the ESXi host, using the Client of VI, so we can use the keyboard and the screen of this server to access virtual machines. Our idea is to use this virtual machine as a workstation.

    Is this possible? or we use VMware server?

    Kind regards

    Cristian Fernández

    It is really not possible. Since the physical ESXi console, you will see only the menus and COS screens.

  • How to find the IP address of the virtual machines from the host Linux

    Hello

    Y at - it a tool that can resolve the IP address of the linux host running VMS, when using NAT and DHCP networking?

    I can find by logging on virtual machines, but I need to retrieve automatically these addresses for the host scripts will not have to be changed manually when IPs change.

    Thank you

    Host: Ubuntu 8.10 64 bit, WS6.5

    Probably the easiest solution is to use static IP addresses... Having said that, what I meant was:

    Each machine (real and virtual) has a unique MAC address. If I create a file (database type) with the name and the MAC address of each virtual machine, then I could use nmap or arp commands to get the IP address. For example, I create a table and put it in a file like this:

    VMName1 00:14:BF:19:45:61

    VMName2 00:0E:5 C: 1 has: 44:1E

    Name of the machine 3. etc.

    Then I could run a combination of arp and/or nmap to find the MAC address of active machines and their respective IP addresses. For example, running:

    sudo nmap - sP 10.0.2.0/24

    This gives on my local network:

    Starting Nmap 4.76 ( http://nmap.org ) at 2009-08-14 18:09 EDT

    Host 10.0.2.1 seems to be upward.

    MAC address: 00:14:BF:19:45:61 (Cisco-Linksys)

    Host 10.0.2.99 appears to be upward.

    MAC address: 00:10:83:BB:08:99 (Hewlett-Packard Company)

    Host 10.0.2.130 appears to be upward.

    MAC address: 00:0E:5 C: 1 has: 44:1E (Motorola BCS)

    Host 10.0.2.134 appears to be upward.

    Nmap done: 256 IPS (4 hosts upward) scanned at 3.71 seconds

    So, now, I know that the machine VMName1 with MAC 00:14:BF:19:45:61 has IP 10.0.2.1 and is it my Linksys router.

    Just a thought.

    Hi, you are almost there! When you look at the Add - ons you must select the Extensions on the left side, and you should see and your AdBlock plus. It can also be a button on the bar of 3 menu - but I'm not familiar with that particular module so cannot be sure about that.

    Thanks for reading & a helping hand

    Tgirl_Alana, welcome to the forum.

    Here is the page of 'product' for the computer.  If you look in the section titled 'Memory upgrade information', it shows the maximum memory as 32 GB with a 64 bit OS.  It is dual channel memory architecture.  Therefore, you should check the memory stick existing brand and match exactly.  Otherwise, dual channel does not work correctly.  Running dual channel memory is faster.  If you does not match the existing memory, it may be better to buy two new sticks as a set.

    At the same time a long time ago there was a way to register for notifications by e-mail of new updates, I have not seen this for years.  Many products have an application that can be selected when the drivers are installed to check and install updates regularly.

    I prefer to manually verify updates, for your printer, you can get updates from HP here.  I see there was a relatively recent firmware update it.
