Data copy from MD3000i to NX3000

HI,

I need to move the entire data from MD3000i (20 TB) device to NX3000 device.

Is there anyway that i can connect both device directly and move the data?

Can you please help me on this?

NP: I need to complete the data migration in a very short time.

Please help me.

Thanks.

    If the data on the MD3000i is on a windows recognizable file system, you should be able to map the MD3000i virtual disks onto the NX3000. At that point, you can copy the data over or just use it in that fashion. This is because the NX3000 is expandable using MD Powervault products.

    Dear Mohan,

    Thanks for your immediate response.

    Yes the data is on NTFS file system only.

    A clarification, "map the MD3000i virtual disk on NX3000" mean, physically connect the MD3000 to NX3000 or different?

    Also, to copy, is there any option available in NX3000 to copy the data from one Disc Group to another or one Virtual Disc to another? how to do the copy?

    Will it copy over network or internal - i.e., between devices? and how much will be the transfer speed approximately?

    Kindly clarify me.

    Thanks much.

    As it's an MD3000i, you should be able to use the network to transfer the data.

    Probably better if the network was separate from your normal user network to avoid a decrease in performance.

    You would need to add the NX3000 host into MDSM and check that the iSCSI initiators on the host are setup to recognise the IP addresses of the array

    By mapping the MD3000i Virtual Disk on NX3000, I meant that you can set up iSCSI sessions from the NX3000 to the MD3000i, create a host on the MD3000i for the  NX3000 and then assign the Virtual Disk that you want to copy over to the host - NX3000.(Note, the VD should be assigned to only 1 host at a time to prevent data corruption)  Once you do this, if you go to the Disk Management area of the NX3000, you should see the same VD there. At that point, you can use any backup software to backup the files, or just copy them to any other VD.

    The backup would take place over the iSCSI network between the NX3000 and the MD3000i. It is difficult to predict the transfer speed as it will depend on the type of files, the nature of your disks, the network, etc.

    Dear Mohan,

    Thanks for your great assistance.

    I've some more queries. Do we have iSCSI Target on NX3000 as well?

    So that i could connect the Virtual Disk of NX3000 in the servers in the network and copy parallel?

    Thanks,

    Prakash

    Hey Prakash,

     I don't uderstand the question. What do you want to accomplish? It might help if you can draw an image of the setup that you are envisioning and share that.
