Storage FAQs

What happens to my data when my server shuts down?

Data stored on your virtual drives is persistent and will be available when you restart your server, just as it would be on a physical hard disk. This means that you can install software and save data exactly as you would on a physical server, unlike some other cloud solutions.

What is the maximum size of a single drive?

The maximum size for a single drive is 500 GB.

What is the minimum size of a single drive?

The minimum size for a single drive is 5 GB.

How do I attach more than one drive to a server?

You can set this in the server configuration page. (Click Edit when your server is powered off to find this page.)

Can I attach one drive to more than one server?

No. However, you can run filesharing protocols such as NFS or Windows File Sharing from one server to another over a private network VLAN. If you need advanced clustering support, you might want to contact our sister company, Melbourne Server Hosting.

I have uploaded an ISO9660 image (.iso file). How do I boot a server from it?

On the server configuration page, set the drive media type for the drive containing the image to cdrom and ensure the boot radio button is activated next to it. If you are installing a server from the CD, remember you will also need another drive attached onto which to install your operating system.

What is the difference between IDE, SCSI and Virtio drives? Which do you recommend?

In practice you should stick with the IDE emulation, which offers good performance and compatibility. The SCSI and Virtio drive types are intended for specialised applications. (Note that our virtio drives have writeback caching enabled, so you will need Linux 2.6.32 or later, which supports barriers over virtio, to be able to use these safely. No released version of the Windows virtio drivers support barriers, so the virtio block transport cannot yet be used safely under Windows.)

What storage performance can I expect?

You should be able to achieve around 30-40MB/s streaming read and write performance from your virtual drives. However, contention with other users accessing the same underlying RAID arrays can result in lower performance, especially at peak times. This affects writes more than reads as we cannot safely cache disk writes as aggressively.
