Utility Storage Service
General Information
The Utility Storage Service provides a low-cost, large-capacity storage solution for research and general use, and is ideal for archival purposes as well as for low to medium I/O performance storage needs. The storage volumes are provisioned over the campus network, and therefore, there is no need for any physical connection to client systems, other than the normal Ethernet connection.
Subscription
The Utility Storage Service can be subscribed using the online form provided here. You will be contacted on details of your project’s WBS number for billing purposes.
As the storage service is for archival of large data files, the minimum size per subscription is 1TB. Please contact the Utility Storage Service administrators (see contact information below) for more details on this.
Requirements
To be able to make use of the networked storage, subscribers must have a server that is already connected to the campus network with fixed IP address. Only Windows and Linux/UNIX operating systems are currently supported. The following are the protocols used to mount the storage for each of the operating systems.
- Windows servers - iSCSI
- Linux/UNIX - NFS
If subscribers do not have a server, they can subscribe for a virtual machine from Computer Centre. For more information on this service, please see the Computer Centre’s VM subscription web page.

FAQs
- How is the payment done?
After submitting the online request form, the Utility Storage team will contact you for information on your project’s WBS number. You will need to supply us the name and contact details of your finance office, as well as get the finance officer to endorse your application to make use of your WBS number for this subscription. - Can I mount on to more than one server?
We provision the volumes using 2 different protocols, NFS for Linux clients, and iSCSI for Windows clients. Only NFS volumes can be shared among 2 or more clients. iSCSI protocol in general is for 1-to-1 connections between server and client. - I am not able to connect to my iSCSI volume.
The following are the steps for connecting to the iSCSI volume from your Windows server:- Start up the iSCSI Initiator and in the Targets tab, fill in the IP address given to you into the Target: field and click on Quick Connect.
- A pop-up window will show you the target that is connected, click OK to close the pop-up window. If there is no target connected, then check your network settings, especially your Windows Firewall to ensure that the IP address is not blocked.
- On the Volumes and Devices tab, select Auto Configure to retrieve the disk.
- Launch the Computer Management and find Disk Management utility under the Storage section. Format the new disk that has been added to the system.
- The disk is now ready for use.
- Do you charge GST?
No, we do not charge GST. - Do you provide backup services?
No, you will need to manage the backup of your data stored in the provisioned volume. - How do I ensure higher reliability and availability of my data?
You can subscribe to a second replication volume, which will be located on a different server in our data centre. You may make use of this volume to backup your data for higher reliability and availability.
