HI ashishs

I'm going to move this question to the right forum - I don't think this is a CE question.

Let me know otherwise - Thanks

Ok, thank you....I got the update, there is no option, simple copy / past.

As nutanix not worked as NAS with hyperv (required licence), Neeed to create VM and assigne LUN as a drive, so users will access the drive using VM IP address....

Hi,
there are multiple ways of moving data from a non Nutanix system to a Nutanix system. Got a few questions before i can point you in the right direction.

1, Is it VMs you want to move to Nutnaix?
2, If yes on 1, what hypervisor are you running today?

thanks

ok, good to know. is your intention to use Nutanix AFS or VMs providing NFS access to VMs?
See this for Nutanix AFS infotrmation http://go.nutanix.com/rs/031-GVQ-112/images/acropolis-file-services.pdf

AFS required licence, so VMs providing NFS is only option for me. Need to create VM and assign LUN as a drive...

Let me know if anyone have any other options...

well you can use VM with one virtual disk, VM with multiple virtual disks (in a stripe or as standalone targets) or VM with ABS. One way or another you need to do the file copy between the servers.
Remember the oplog limit per vDisk which is 6 GB so you'll get better performance with multiple virtual disks compared to one large single virtual disk if you got a lot of changes going on.

Are you looking at Linux of Windows VM as your NFS VM?

Looking for Windows vms....I have 30 TB data with 7 shares on EMC, what will be the best way...
1. Create 1 VM and create 7vdisks?
2. Crerate 7 vms and assign 1 vdisk per vm?
3. Any other?

hard to do a design based on only the conversation above since i have no idea about access pattern, working set (changes per day), number of file, catalogs, users, systems and so on. Last time i did a VM based NFS design i used multiple files where no one was bigger than 500 GB and have multiple of them in a LVM group.

thanks

hey ashishs - We're happy to help out with this via our PS team if you'd like, as we do this exact thing all the time in customer PS engagements to design your specific environment.

Otherwise magander3 is right, without knowing all of your requirements, its hard to definitively say exactly the right configuration for you. In general, more vDisks are preferred, but you also dont need to micromanage vDisks down to an ultra granular level. For a large file server, I'd roughly say 5-10 vDisks per VM.

Also, feel free to scale out the number of file server VM's you have, so that things like backup and recovery are easier.

Jon, currently we are using EMC VNXE3100 and have 7 shares of total 30 TB...attached screen shot of shares size...
Please let me know how many vms i need to create and how many drives i can assign per vm....?

Hi,
unless we get the information i was talking about we can't make any recommendations. Please engage Nutanix Services for a complete desig or use the guidelines me and Jon have provided to test different setup options.

hey ashishs - Magnus is correct here, its hard for us to tell you exactly what to do, besides the general guidance that we've already given you.

If you want us to do the work for you, we're happy to do that via our great professional services team. They literally do these exact types of migrations every single day, and can be engaged on a paid basis to do the work on your behalf.

Also, I dont see a screenshot attached here.

Hi,
please use our provided general recommendations and try your way forward or if you want a complete design you need to engage Nutanix services. We can not design a proudction environment in a cummunities thread.

Great to hear ashishs. What file server design did you end up going with? Server OS, number of vDisks, etc? Would be good for others who find this thread in the future

Its simple file server, where around 200 users accessing their files. Usres are mainly used excel, word files. Server config is 4vCPUs, 16GB RAM, 6TB vDISK (Used space 3.2TB)
