Steam

Updated: September 28, 2024

Setup Steam for use on a Synology NAS ( technically any system but we gonna focus on Windows)

This will create an iSCSI, that a computer will treat as an internal HD even though it is actually connect via LAN.
It may be too slow for some games so just try them and if one give trouble you can always move it back locally.

A few times now some of the settings have changed. As of the date of this writing
Synology incorporated iSCSI into the SAN Manager and Steam changed how to move games. A few min recommendations:

• A 10GB LAN Connection
• SSD/NVME drives if possible.
• Place non-intensive apps on iSCSI
• Keep Environment games local.

Synology

First thing it to create some space by adding a LUN (Logical Unit Number) on the NAS.
Then we will use the LUN as an iSCSI (Internet Small Computer Systems Interface) target.

• Launch SAN Manager
• Click on LUN
  • Name: Steam
  • Volume 1
  • Capacity:
  • Thick Provisioning
• Create new iSCSI target
• Permissions: Allow All R/W

Now Proceed to Windows/Linux/Mac

Network

My Nas has a firewall actove, so we need to allow Port 3260.

• Control Panel > Security > Firewall > Firewall Profile > Edit Rules
  • Create > Set from a list of built-in apps > iSCSI service > Ok + Apply

Windows

We are going to use ISCSI Initiator to Network Map

• Discovery Tab
  • Discover Portal
  • Enter IP of NAS, leave port at 3260
• Targets Tab
  • Select synology target
  • Click connect

Next, open Computer Management to label and format new drive.

• Go to Disk Management
  • Select Disk <#> to initialize
  • Keep as GPT
  • Below should now show the unallocated volume
  • Right Click - New Simple Volume
    • Next - Give all the space
    • Assign Drive Letter
    • Next - NTFS
    • Give new volume label name
    • Perform Quick Format (no compression)

Move onto Steam

Steam

Start out Steam > Settings > Storage

That’s it! Enjoy your new massive volume!
