Question about ESXi and NFS

Greetings!  I'm hoping to get feedback on the following possible scenerio.

Computer 1:

The computer that is running Windows Server 2008.  Large amount of storage available, via dedicated hardware raid or 'software' / raid ICH10.

Computer 2:

Computer running ESXi v4 (installed on the local hard drive).  Core2Quad w / 8 GB RAM.  Responsible for about 4-5 virtual machines.  Each virtual computer will be low IO load (DCs environment lab, MySQL server, web server).

I have three questions:

1. are there any problems with the use of the space on 1 computer through Windows 2008 NFS to host virtual machines that will run on computer 2.

2. because I do not use hardware RAID on computer 2, I won't RAID1 for redundancy.  If the hard drive fails, but virtual machines are on a redundant protected NFS share on Computer1, is there loss of data outside the need to reinstall ESXi on a new hard drive?

3. someone can tell the performance of a 'software' RAID (probably RAID5) NFS share (ICH10, etc.) from the point of view of virtual machines hosting?

Thanks in advance!

1. are there any problems with the use of the space on 1 computer through Windows 2008 NFS to host virtual machines that will run on computer 2.

Although the NFS Windows service is not the most ideal, it will work fine. You want to make sure there is no automated etc. updates and limited storage functions of the machine.

2. because I do not use hardware RAID on computer 2, I won't RAID1 for redundancy.  If the hard drive fails, but virtual machines are on a redundant protected NFS share on Computer1, is there loss of data outside the need to reinstall ESXi on a new hard drive?

It would not be otherwise than a hardware failure on any machine. You don't have the risk of data damage whether physical or virtual.

3. someone can tell the performance of a 'software' RAID (probably RAID5) NFS share (ICH10, etc.) from the point of view of virtual machines hosting?

Without hardware raid with a caching controller you won't have better disk performance. Controllers setting cached on RAM and will require a battery to protect the cache failure.

  • a few questions about ESXi and SAN CF with HP P2000 G3

    Hello everyone!

    I am new to ESXi and SAN, then I need help for her.

    I have Encolosure C7000 system with 4 blades BL460c already installed ESXi 5.1U1 (HP custome ISO image). Everything works fine now, but I do not understand something:

    -What is the management network which I use vSphare Client to connect to? It is a private network to manage ESXi servers what difference with VMnetwork used by Virtual Machines? Because I've set up an IP address for this connection manually, but it is of course separate with IP addresses, I used on Virtual Machines.

    -If my system has problem, so I have to reinstall ESXi, license keys can be used again? Already, I have 8 license key for 4 blades (2 CPUs per server), but they have not yet used. Because I am new to ESXi, cause I had to reinstall ESXi several times to understand.

    -When I install successful ESXi, I don't know how to start working with SAN. What should I configure P2000 before it be plugged into the SAN switch? Or I can plug it then config later? Because I don't see it on the ESXi server. And on the OS I installed on the Guest Virtual Machines, I see nothing new in Device Manager. I thought that this guest operating system will detect the mezzanine card. But I see only mezzanine card that connect to the P2000 by SAN switch in ESXi (see image here http://img203.imageshack.us/img203/684/dsc04088k.jpg ). To my knowledge, I think that ESXi server have to detect the P2000 as hardware device. Can someone teach me step by step install and configure a San on ESXi? Or show me a tutorial because I searched but only iSCSI results.

    My devices:

Because I've set up an IP address for this connection manually, but it is of course separate with IP addresses, I used on Virtual Machines.

    Yes, it's a separate network used only for traffic management between ESXi hosts and vCenter - it is also the network used to connect to the environment - that's different, then the network used by your virtual machines

    -If my system has problem, so I have to reinstall ESXi, license keys can be used again? Already, I have 8 license key for 4 blades (2 CPUs per server), but they have not yet used. Because I am new to ESXi, cause I had to reinstall ESXi several times to understand.

    Yes the license keys can be reused, and if you use vCenter licenses will be managed by vCenter

    -When I install successful ESXi, I don't know how to start working with SAN. What should I configure P2000 before it be plugged into the SAN switch? Or I can plug it then config later?

    Yes, you will be able to configure the San later - by default, the virtual machine will not see the SAn, as it is virtualized by your ESXi host - all the VM will see is a virtual SCSi disk - this doc's guide to vmware for storage - http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-511-storage-guide.pdf - you can visit the website of HP they might have documentation on configuring P2000 for vSphere -.

So, followed by all as should be. The prompt update from apple was quick time, iTunes and airport, I checked all and then updated. Then I loaded office 2010 and obtained throughout the process from the Microsoft site. On the last part of the installation, the installation failed due to a mistake of hanging iTunes. I tried again and again, I fixed the update to iTunes to add and remove the section of windows. Then, I got different errors.

  • Basic question about ESXi networks

    Hi all

    It may be a very simple question for you but I am new to ESXi and I need your help.

    I have a configuration of ESXi envionrment like that.

    192.168.1.200 - ESXi Server

    192.168.1.50 - a Linux machine

    192.168.1.60 - a Windows 8.1

    ESXi server connects to a router and the network is 192.168.1.0/24.

    The topology just like that.

    Screen Shot 2016-07-03 at 11.08.25 AM.png

    My problem is,

    1. I have a Mac machine connect to the same router. There is a web interface built into the Linux box. Can I use the Windows 8 to go, but I can't use the machine to physical Mac do. The firewall is off turn in ESXi already

    2. How can I make the two machines able to access internet?

    Thank you!!

    After taking a second look at the configuration of the network, I have seen that you have configured a VLAN ID on the port group. Assuming you are using a router not supported (i.e. without ports trunk/tag), this may cause the problem. Please remove the VLAN ID to see if that solves the problem.

  • Question about snapshots and virtual machines

    Hi all

    I have a small question about snapshots. I use VMware for about 6 months and I read about snapshots and how they work but still have a question to make sure that I understand how it works and it will work the way I think it works.

    I have a Windows 2003 server, which is a virtual machine. I have an application that uses MSDE database. I want to upgrade the database to MS SQL 2005, but to do this I need to back up the MSDE database, uninstall MSDE, and then install SQL 2005 and move the SQL database. This happens on the same VM.

    What I was thinking if I well Snapshots correctly is to snap turned the virtual machine before doing anything. Then do my upgrade steps and see if everything works. If its all messed up so I should be able to return to my shot and everything should be the way he had. What is the good? One of the main reasons I moved the server VM was because of this upgrade.

    After reading the documentation for the snapshots, it's how I undestood it. Pretty much any change could be reversed with snapshots. I wish just they had put in a few examples in the PDF file. Also it would be the same for all type of grades of the OS? Could I snapshot a Windows 2000 Server, and then "in the upgrade of the square" to Windows 2003? I've cloned a VM to do this but was curious about whether snapshots would be just as easy.

    Thanks for your help.

    That is right.

    Exactly the same thing for the upgrades of the OS.

    Perhaps the most important thing with the snapshots is to keep an eye on them and don't let them sit too long or become too big.  You have described the use cases are very good uses for snapshots.  Just make sure you have a solid plan with a schedule set, so that you can come back or validate changes before the snapshot becomes too large.

    Good luck!

  • Question about CR and LF

    Hey guys,.

    Quick question on LF and CR. As you can see I'm LF and CR of writing to a text file and because directly.

    However, I don't get the CR at the time where I read it. Why is this? Is it because Windows ignores the CR?

    There is an option for handling of CR/LF characters and explained mentioned in the "Advanced" section of the article for help!

  • M30-832: Questions about memory and DVD player

    Hi all, new to laptops up to have a few questions! First of all, I have a Satellite M30-832.
    1. He has on the dvd player on the side of the Compact disk with re-writable below image and sign dvd R/RW under. That means it is a DVD burner as well? It does not sem to recognize blank DVDs and I was under the impression that it should be possible to write about them!

    2. can I upgrade the memory with memory DDR - RAM modules or does take a special type? And how to change them!

    Thank you very much

    Hi Richard,

    From what I can find your M30 832 is equipped with a DVD burner so you should be able to burn DVDs (the specification says you can only burn at X 1 speed for DVDs).

    You should be able to update your RAM to a maximum of 2 GB and I recommend you buy a quality mark to avoid any problems. Your user manual should have details on how to change the RAM modules, but generally it will be to remove a panel of access (usually on the bottom of the unit) and then releasing it two clips (one on each side of the RAM modules) plastic spring-loaded and gently raising the output modules.

    Please make sure that you either wear a wristband anti-statuc dirt or this earth you yourself before accessing RAM modules. They are very sensitive to electrostatic.

    You can find suppliers of RAM suitable if you GOOGLE 'M30 832 RAM.

  • Question about phone and / or Android 1.5

    I have a question or a statement that needs confirmation. If someone could be good enough to help out I'd appreciate it.

    I am a heavy Texter and text on a daily basis, probably an average of about 250 + texts per day. Also, I noticed and I took County, after about 4 hours of texting the android keyboard and also the swype keyboard, affecting the time key to key response starts to slow down and get slow and ultimitely is unbearable to the text with. Even with the home screen and sliding screens from left to right, and as I said it doesn't happen only after some hours of use of the phone. So, I have to restart the phone and repeat for it keep to become lazy and unbearable to text with. I usually reset every morning or when I wake up. This is nothing compared to my sisters Mytouch, which is in fact older than my phone, it can affect his day at the time and not get done with the delayed touch response. I also noticed that his phone is running Android 1.6.

    Now my concern is, if I'm the only one knows this or is it due to a defective phone. What is the Android obsolete 1.5 that many people are talking about who is performing on the phone in this way.

    Basically, it's because of 3 things.

    1. history - more history, more than it takes to load. (If you wipe all messages and try again, you'll see what I mean)

    2 android 1.5 - don't know what the reason, but even on 1.6 devices SMS language delay is AVERAGE less.

    3 Swype - if you have enabled, it tends trolling more than the default android.

    It is not your phone, it's all phones Cliq/Cliq XT... 1.5 hate text messaging.

    In addition, your phone will work more effectively without a task manager. They are nice to have if you need something CF or to extend the life of the battery (no), it actually takes your phone like some processes that would otherwise, and you also have the risk of frost on the phone all together because some group programs are essential and cause the home screen all recharged after their closure. I would like to refer to this site in order to better explain.

  • question about SQL and VMDK places

    Hello world. Im kinda new here so please be gentle

    I'm confused on the locations of the files for sql.

    At this moment I have 1 with 3 vmdk files sql server executes a muscular 100 GB sql database.

    My disks are as follows

    1 OPERATING SYSTEM

    2 DB

    3 newspapers

    They are all thick and they are all stored with the virtual machine in the virtual machine configuration.

    It lies in a cluster HA/DRS and we use them both.

    The question boils down to performance.

    If my VM is stored on DATASTORE_A and the VM folder on this data store has all the VMDK files in it, it would be safe to say that they are all on the same disk as much as vsphere is concerned.

    Now to get best performance, I want to separate my VMDK files to separate data (with faster operation) warehouses to avoid conflicts of drive on my current data store. What is the right way to go about this?

    How separate you your VMDK to other data warehouses, and enjoy other performance data store? WE do not use DTS at all so im sure it although we use HA/DRS in our group... and yet, I don't think that it is important in this case... just more of an FYI.

    What do you do to get your SQL servers to run in vmware?

    Seems like a basic question.

    The answer seems easy. Separate disks so that they do not fight.

    'S virtually done it with VMDK but the data store underlying is 1 speed and they all exist on this subject, so... How to separate them at that level for best performance?

    Also... once I keep them separated, how can I keep my sanity by knowing my VMDK are not with the virtual machine? This kind of made a mess . Of course the performance takes a front seat for my mental health.

    Thank you all

    1. If I sVmotion my other vmdk files via the advanced options of one in another data store, it will create the files folder structure based on my VM name and place the vmdk inside?  (I guess I could just test it and see).

    Yes, the VM configuration file (.) VMX) will be modified to point to the new location of the virtual disk. You can use the virtual machine property editor to check for this, once the Storage vMotion.

    2. with regard to the disk controller, I assume you mean a virtual controller by VMDK in the vmx / correct the settings of the virtual machine and not a phyical on the hardware controller? (IM pretty sure I know the answer here but I just want to be clear).

    Yes, the virtual controller is correct.

    If so, what type of controller? LSI Logic or it would benefit all a paravirtual adapter?

    As long as your operating system is supported, go with the PVSCSI every time - especially for newspapers and the controller file data.

  • Question about printing and resolution

    Hello

    I have a trial version of PE13 tries and tries to reconcile with printing and resolution.

    I also read this informative tutorial here:

    How Image resolution affects printing - Photoshop tutorial

    This is the image I want to print:

    PhotoshopQ.jpg

    In the above tutorial, the author states that when printing, resolution 300 is the best and not the 79.3 px/inch I. When I change this 79.3 to 300, the image of Marilyn becomes tiny, so my question is how can I have a picture that would fit perfectly on photo paper A4 with a white 1 "border around itself (which means that the size of the image would be 8" x 6 ") while maintaining a 300 resolution?

    I go about it the right way, am I not?

    Thank you very much.

    Steve

    While the recommended resolution to see images from a short distance is 300 dpi, the normal resolution for screens, which was 72 PPI doe not exceed 90 ppi, except for the new screens hidpi. Which explains the "extended" effect that you see when you look at the 100% view (an impression pixel corresponds to a pixel on the screen). The print size will be what you chose: 6 * 9 inches.

  • Question about ESXi 5 use cases

    Hello

    My name is David Baldock, and one of the IT guys here at work suggested that with the help of VMware ESXi 5 could allows me to accomplish what I need to do on my system, without having to close and restart between Linux and Windows 7 for different tasks.

    I recently upgraded my PC to a processor Intel Core i7 - 3930K on a motherboard ASUS X 79 Sabertooth (VT - d support in BIOS) with 32 GB memory DDR3-2133 2 NIC and an AMD HD graphics 7970.  While I have not a card SCSI or SAS in there, I have a 256GB SSD OCZ Vertex - 4 2 x 120 GB OCZ Vertex 3 Max - SSD IOP, a 600 GB 10 K RPM Raptor H/D and a Blu - Ray SATA writer.  The SSD & H/D is on SATA 6 Gb/s ports, and the Blu - Ray is on a SATA 3 GB/s port.

    I normally run Linux on my PC, but the photo post-processing software that I use (DxO Optics Pro 7.5) works on Windows 7 and using OpenCL to take advantage of the computing power of 7970 HD.

    I understand that the VMware ESXi 5 installs as a hypervisor directly on the hardware and then allows multiple VMs to be run simultaneously on the system.

    Read on ESXi 5 (see courses and link below), I don't know if I should add a SCSI or SAS card, or if I can install and run VMware and OS on the SSD Client, using the large Raptor H/D to common storage?  There is a 2 to drive Iomega NAS connected to my network (and I have several external drives with SATA or USB-3 interfaces), with future plans to add in addition to stand-alone drives NAS or a big NAS RAID Array.

    The main question I have is if the material resources are dynamically reassignables between Virtual Machines?  For example, if I'm normally running Linux, then I would most of the CPU cores and the video card to "assign" to this virtual machine - but when I need to process the photos, I want to be able to boot Windows 7 and "reallocation" most of the hearts of processor and Passthrough the 7970 HD for this virtual machine to provide the computing power for the DxO Optics Pro.

    Is it possible to use VMware ESXi like that, or I'm better stop the PC and reboot between operating systems?

    Thanks for your ideas and suggestions.


    Take care
    David Baldock

    For Serial ATA (SATA), a drive connected through taken SAS controllers supported or supported integrated SATA controllers. SATA drives will be considered remote, non-local. These discs will not serve as a partition to scrape by default because they are too far away.

    Note
    You cannot connect a SATA CD-ROM device on a virtual machine on a host ESXi 5.0. To use the SATA CD-ROM device, you must use the IDE emulation mode.

    Regularly on the forums I see people asking if GPGPU computing is supported by ESX, prompting me to write a brief message on the subject:

    YES! VMware ESX supports GPGPU computing. Applications can access the GPGPU CUDA or OpenCL in exactly in the same way that when running in native mode - no changes are necessary for the application.

    =====

    Install ESXi 5u1 on the system, then upward, setting it up as a host server. Then use another computer (Yes, you need to have another system actually configure/use the host) to configure passthrough and others. I don't know if it's available in the free version, so you don't have to try it and see. Be aware that you will be able to use the video adapter on a virtual machine single at some point.

    I just activate DirectPath of e/s on my own host (a nVidia Quadro NVS 290) video card. It requires a restart until it's available, however.

    So, if this works (for you too) enable you, reboot the host and then attach one of the virtual machine to the video card to use. You will then be able to use your other system to open a console window in this VM (from the Client vSphere connect directly on the host server) to do what you want / need.

  • Question of ESXi and Vcenter licenses

    Hello

    I bought vcenter just now as well as some vsphere licenses, however were still about 15 older ESXi servers that I want to upgrade and manage vcenter.

    However, I am a bit confused about the cost of the upgrades for my ESXi free installs to connect to vcenter.  I watched the Essentials Kit where you can buy 3 licenses but it's to connect to vCenter Essentials.

    What is the difference?  I'm guessing that you can not essential home standard licenses to vCenter ESXi...

    I am not otherwise interested in HA or vmotion, I just need a way to access my vCenter ESXi.

    Thank you

    Essential ESXi connects to critical vcenter. for your case, you will need to vsphere Standard to be able to be managed by the vCenter.

Maybe you are looking for
