Many people are looking for a low cost solution for external storage for their free ESXi server. In this article, I will describe how to use a Windows machine and Windows Services for UNIX (WSFU) version 3.5 to create an NFS share that can be mounted on an ESXi host for storage of Virtual Machines, ISOs, or backups. There are a lot of articles like this out there but none of them worked as advertised for me so I decided to write my own.

Because I’m thinking about using my NFS storage for backup purposes my NFS share is called esxi-backup. Call your share what you will.

There are 6 main steps in the process:

1. Installing WSFU
2. Enable SSH on the ESXi Server
3. Obtaining copies of the ESXi Server passwd and group files to the WSFU server
4. Configuring WSFU for accepting ESXi connections
5. Sharing the Windows folder to NFS clients
6. Creating an ESXi Datastore to mount the Window NFS Share.

1. Install WSFU

• To install WSFU you must first download it from Microsoft. SFU Download
• Install WSFU on the desired machine
• Select Custom Install
• Add NFS + Server for NFS and Authentication tools for NFS + user name mapping
• After installation, open the windows services control panel applet and verify the service ‘User Name Mapping’ is setup to startup automatically and that the services is started.

2. Enable SSH on the ESXi Server

• Please note that enabling SSH on ESXi is not supported on production servers. Follow the instructions here

3. Copy the ESXi Server passwd and group files to Windows

• Using a program like WinSCP or Veem fastSCP you need to navigate to the /etc directory on your ESXi server and copy passwd and group files to the WSFU server.
• I copied the files to c:\SFU\esxi-files, that way I won’t forget what the file is for.

4. Configure WSFU to accept connections from the ESXi Server.

• On the Windows platform where WSFU was installed Click Start, Programs, Windows Services for UNIX, Services for UNIX Administration
• Select User Name Mappings on the left hand side then configuration on the right had side.



• Select the Password and Group files radio button
• Then select browse for both the password and group files that you copied from the ESXi server
• Select apply
• Now Select Maps
• Once the Maps window opens, select “Show User Maps”
• Under Windows domain name, Select the windows PC where the users are located and then select List Windows Users, then select list Unix users
• Select a local administrator user from the Windows Users on the left.
• Under the Unix users Select the root account
• Select Add
• Then click apply (upper right)

5. Sharing the Windows folder for NFS compatibility

• Right click the local folder you wish to share via NFS (mine is c:\VMware esxi backup)
• Select NFS sharing
• Type in the name for the share
• Make sure allow anonymous access is NOT selected.



• Select permissions
• Change type of access to “Read+Write” then select allow root access.

6. Configure the ESXi Server to mount the Window NFS Share as VMFS

• Open the VI client and select your ESXi Server
• In the Configure tab choose Storage
• Add storage, Network File System
• In the Server Field enter the NFS server IP address or hostname.
• In the Folder field enter the share name you created above (mine is esxi-backup)
• I used esxi-backup for the Datastore name.

6a. Alternate NFS Configuration
This is an advanced configuration that requires the NFS server is on a separate IP network. I would only suggest this is you know what a separate subnet is and have one configured.

• Open the VI client and select your ESXi Server
• In the Configure tab choose Networking
• Select Add networking
• A new window will open, select VMKernel then select a vSwitch, then give the VMkernel an IP that is accessible via the NFS host.
• Now open the storage option for this host
• Click add storage, Network File System
• In the Server Field enter the NFS server IP address or hostname.
• In the Folder field enter the share name you created above (mine is esxi-backup)
• I used esxi-backup for the Datastore name.

Anyone that has ever put a document in a copy machine and pressed start has scanned an image. Scanning is that easy, what you do with the scan is how you can improve your business.

Scanning is the process of taking a hardcopy document and converting it to a digital format. Instead of keeping the hardcopy documents in metal file cabinets, the scanned images can now be stored electronically in electronic file cabinets. This save space and if setup correctly it can be found quickly and easily by anyone with access to the location where the file is stored.

Scanning can be accomplished in a number of ways.

• Scan to email - The document is scanned from a MFD, using the MFD internal mail client the scanned document is then sent by email to the recipient. In most cases the file is sent in a image only PDF format. That means that the scan looks just like the original hardcopy document but it can not be searched for keywords.
• Scan to folder - With scan to folder the document is scanned to a folder on the network. From there it can be accessed by anyone.
• Scan to desktop - Building on scan to folder, an application like Nuance PaperPort watches the network folder for scanned document. Once it sees a new scan it takes the scan out of the network folder and puts into the PaperPort desktop. At this point the user can convert the document to a text searchable PDF. A text searchable PDF looks just like the original image and it can be searched for keywords. Once it is in a text searchable PDF it can easily be found in PaperPort.
• Middleware scanning applications - Middleware scan applications like NSI Autostore, Xerox SMartSend, and xSolutions Scan Flow Store,  can take scanned images and convert them to almost any file format and send them to a number of locations with little or no intervention from an end user. A common use of a middleware scanning application would be to scan to a document management system like Microsoft SharePoint or Xerox DocuShare. 

That brings us back to the how can scanning benefit you? With scanning you can take all of your hardcopy documents that are sitting in the file cabinet and make the readily accessible for anyone that needs them. This can save you space, time, and money.
