Greeting's, I'm provided with:

1. Windows Server 2012 R2 Standard Edition.
2. SAN block storage (EMC VNXe 1600) with FC connectivity.
3. Blade servers (Dell M630 within M1000e chassis) with FC switch. Each server has 2 Xeon V3 processors totalling 32 cores and 64 GB DDR4 RAM.

I need to implement active directory with 2 domain controllers and folder redirection for all users (user count is at 250 and will reach 1000 in due course). Folder redirection will be used for all customizable folders.

Problem / Question:

A LUN created on SAN storage can only be mounted on one server (Domain controller). Mounting single LUN on multiple servers will corrupt the LUN.

Folder redirection will require ACLs to keep user data secure (ACLs are mentioned here: (https://technet.microsoft.com/en-us/...v=ws.11).aspx). I see that these are NTFS ACLs.

Given the above constraints (hardware / software / requirements). How best can I implement 2 DCs with folder redirection? I have one extra server which I can use.

I have got certain recommendations such as creating a filer server but I'm unaware if the I/O will be acceptable in case where DC's are constantly asking a file server to read, write user data?

What would be the best way to go about implementing folder redirection in this case?

Create multiple LUN's on the SAN mate, why have you only got one? Each LUN can then be assigned to a datastore. Create multiple datastores and assign servers to each DS.

I/O would depends on the nodes not the servers in youir case but RAM could be an issue with 1000 users accessing DNS, NTFS and shares at anyone time.

It is going over my head but just have the one DC connect and share with 1 connection at a time.  I remember there was this big "LUN" thing from a Texas project when I worked corporate and they had a problem with something.  I was a desktop guy.  I only heard things.  It was a unix based "LUN" and it was expensive and a piece of crap but engineering had to use it for some project.  I guess a "LUN" is the file store system.

LOL LUN's are a logic number which identifies at which point a file system is created. Think of it as a target.

I dont believe it has anything to do with UNIX at all and they are incredibly handy for splitting raids and volumes into smaller chunks
