Server with 10 TB LUN attached by physical brutes FC connection works, but second 10TB seems to be limited

I have an ESX Server with two virtual machines on it, one of the servers is to store medical images. These virtual machines are essentially backup servers to servers that are physical (not virtual).  The main server is a physical server with an attached IBM DS4700 direct and secondary sandbox. I have 20 TB of data spaced so far.  Side virtual server also direct a of DS4700 attached to the area of ESX and he sees the first 10 fine to, as a single disc, and Yes, I know that this seems to go against the norm.  In any case we work for well over a year to date.  I add the second 10TB and I now seem to be limited by the expected 2 TB-512 b per LUN through documentation.  I would like to know why I was able to create the first 10 TB LUN without problem using physical RDM mode, but when I try to add the next physical drive from RDM on the same server (see 9.54 TB LUN very well), using the same method, why windows or should I say VMWare ESX is not being able to see the 10 to complete this time.  I am aware of the supposed limits, but the first works fine, why only now did he not see it.  To clarify the "Add" function of VMWare 9.54 Tb thin LUN during the creation of the new disc, but in Windows, it only recognizes the first 1.5 to (so it seems) I have not actually tried to format the volume in Windows and have yet once removed from the virtual machine.

Windows 2008 64 bit standard on top of ESX 4 Enterprise Plus connected via direct fiber DS4700 and DS4000 with 10 TB on each table.  The virtual machine has been improved to version 7 machine and I have NOT tried add the second 10TB still with the new VM version. Thought I would ask first.

Yes, you can map your volume of GPT in any physical Windows but I can't tell if you will experience data corruption or not, as I know that more than 2 TB volumes don't are not supported with current versions of vSphere.

It is a good article on 2 TB limit, and how taken Windows support that: http://blogs.technet.com/b/askcore/archive/2010/02/18/understanding-the-2-tb-limit-in-windows-storage.aspx

  • Conversion of a server that has SAN LUNS attached

    Hello

    Need help.

    I need a file server, which currently has 4 mapped to the EVA SAN drives, each drive is almost 1.6 TB of P2V.

    I also have the CD VMware converter acronis.

    How can I get it work? as I'm not able to migrate the attached SAN LUN due to space issues.

    Any help appreciated...

    How can I get it work? as I'm not able to migrate the attached SAN LUN due to space issues.

    You don't need to convert the SAN disks, ignore those.  NPIV can be used to attach these LUNS later once it is converted.

    Use VM Converter, convert JUST the boot disk for the file server.

  • Network Diagnostics says that the connection works but server problems?

    I have Windows Vista on a Lenovo laptop. I recently got a new 2wire modem/router all-in-one of at & t wireless.

    When I connect to the internet on the laptop wireless it says that I'm connected to the internet and when I get on my browser I get a server error. When I go through the window of diagnosis of windows it says that my internet connection is fine. I clicked on the option to turn off my card and plug it in again and my internet works then for about fifteen minutes before receiving once more the server error. Help, please! I have always connected and remained perfectly connected before to acquire this new modem. Another laptop I have is online and remains very well.

    Is this a computer problem? Or a microsoft connectivity issue?

  • How to backup VMs that have RAW LUNS attached with TSMserver v5.5 and TSMclient v6.1 in VCBproxy in a task (backup script)

    Hallo

    I have several virtual machines that have RAW LUNS attached to them.

    Question 1: Is there a way for me to use (free LAN) save those VMS with VCB + TSMserver 5.5 + TSMclient 6.1 - in mode (an automated task - script), which local VMDK disk backup is backup with FULL-level and fasteners LUN RAW to the VM backup files of the virtual machine level. Does the solution support?

    Question 2: Is there a way in a task (separate in the 'pre' and 'post' script) as a single disc with vcb backup - for example when VM have a disk VMDK more attached, only a VMDK disk backup for is a primary partition on a virtual machine?

    Note: Backup free LAN for backup of the VCB proxy any type (level FULL or FILE) is correctly and fully functional.

    Hello

    Question 1: Is there a way for me to use (free LAN) save those VMS with VCB + TSMserver 5.5 + TSMclient 6.1 - in mode (an automated task - script), which local VMDK disk backup is backup with FULL-level and fasteners LUN RAW to the VM backup files of the virtual machine level. Does the solution support?

    If the RAW format is really a ROW then you can do a virtual RDM and Yes, VCB will save help file or full. If she is not a ROW but a RAW, then only the VMDK can be saved via VCB.

    Question 2: Is there a way in a task (separate in the 'pre' and 'post' script) as a single disc with vcb backup - for example when VM have a disk VMDK more attached, only a VMDK disk backup for is a primary partition on a virtual machine?

    Not only a single disc that I saw that it's all or nothing. If you don't want to VCB to backup a drive, you can mark it independent or if it's a RDM make non-virtual.

  • A physical server with 2 NETWORK interface card using a virtual machine as IPS (transparent VM) and everything should work normally?

    Hello guys.

    Is there a diagram that I made, using for my self this question.

    2067917_1.png

    As you can see, I have a physical server with 2 NIC I don't want to use a VM (with Snort) as IPS / IDS system for inbound traffic on the management of VLANS. Is it possible to use this VM in this way (as an IPS/IDS, VM with two NIC without any routing work?)? Maybe you have a suggestion, how can I achieve this, as easy as possible? Maybe you have an opinion, what OS unix system do I use?

    Thank you for your time and your answers. Any useful information is much appreciated.

    Yes, it should work. You need to look out for, it's that the 'outgoing' NIC is not connected to the same physical switch as the entrant and that there is no link between these two physical switches, because this would create a loop of layer 2 on the network.

    I haven't worked much with Linux, but I don't see that you would have a problem to find some Linux/Unix with the possibility to bridge two network cards and use some software IPS to inspect the traffic.

  • Clone a physical server with converter

    When the cloning of a physical server with converter and selecting Configure the VM when completed does change on the physical server?

    My original physical server becomes inoperative?  I would rename the virtual server and give it a new IP address, but also want to continue to use the original physical server.

    Welcome to the community - but be aware that if you do not want to run two machines on the same network, your willingness to care about the host name and IP address to avoid confllicts.

  • UCS C420M3 server with VIC 1225, can't see the ethernet LOM ports

    Hi Guyz,

    We have C420M3 server with VIC 1225 connected on PCIe slot, with fabric Interconnet.

    After you have installed the OS & drivers, vNIC created the VIC 1225 by the service profile appear, but 4 gig on server LOM ports do not appear.

    Any idea. ?

    Thank you

    If you incorporate your rack server to UCSM, you will be able to use the LOM ONLY ports for traffic of Mgmt, when you join the server mode to 'Dual Wire'.

    It is useless (unless you have one for a special reason, I do not intend at this very moment) to use ports LOM, once you entered the server, precisely because of the 1225 VIC is not a regular NIC card or a regular HBA, it is indeed a CNA (Converged Network Adapter), which essentially allows you to do in a map , what you would do with two (which means "what you would do with a NETWORK card and HBA separated')

    When you have a VIC card, you actually have the ability to create up to 256 virtual interfaces (this is the capacity of the equipment, always limited by the operating system, please keep this in mind), this is the reason why, after the server is integrated, entirely rely on the interfaces in the Service profile instead of the physical interfaces.

    Find more info here:

    http://www.Cisco.com/c/en/us/products/interfaces-modules/unified-computi...

    You have a specific reason to use the LOM ports rather than create 2 additional virtual interfaces in Server Service profile?

  • Web server with CVI

    Hello

    I want to know if it is possible to create a webserver with CVI so that I can connect my application and see the data with internet Explorer?

    Backround: we run a CVI-application on a computer within a network. On this computer, collect US data from different systems and publish these data in a sign of the CVI. Users who want to see the data, connect to the computer with a remote control software.

    Now, we wondered if it is possible to create a web server with CVI. And if the user cannot see the data on his computer using internet Explorer.

    In the forum, we found a few messages very old. Are there new items on this subject?

    Thank you

    No, by default the server listens on all interfaces.
