FAQ

This is a list of the most frequently asked questions.

Installation

How do I install the software?

We provide an installable ISO image. Use this image to install on physical hardware or virtual machines. For physical hardware, you will need to burn the image to CD, DVD or USB pen drive.

What operating system is Zetavault based on?

Linux. We use the Linux 4.4.x kernel.

Can I install the software on an existing Linux system?

No. The installer needs to install the dedicated OS. It is not possible to install as an application on an existing system.

What Linux distribution is the software based on?

Ubuntu 14.04 LTS.

Why Ubuntu?

For us, Ubuntu is easy to customize. For our users, it is easy to install and manage.

Ubuntu is used to run Netflix, Uber, Wikipedia, Dropbox, Paypal, Snapchat, Spotify, Pinterest, Reddit and Instagram. Plus thousands of other companies and organisations.

If you use the Internet, then you already use Ubuntu on a daily basis.

See http://insights.ubuntu.com/2016/04/07/ubuntu-is-everywhere for more details.

What system do I need to install Zetavault?

Any 64-bit X86 system on which Linux can be installed on. 32-bit systems and non-X86 systems are not supported. Virtual machines are supported and are a useful way of evaluating the platform.

VMware, XenServer, Hyper-V, Linux KVM and VirtualBox hypervisors are supported.

Is a trial version available?

Yes. A 60 day trial is available after installation of the ISO. See the Download page.

What happens to the software at the end of the trial?

Only the management software will stop working at the end of the trial period. We don’t touch any data you have created. The storage services (iSCSI, NFS, SMB, etc) will continue to run so any network clients you have connected can still access their data.

There is no need to re-install Zetavault if you are purchasing a license. Just update the system when we have confirmed payment.

Pricing

How much does it cost?

The software license is calculated on the amount of total storage in the system. This is done on a decimal TB basis since that is how hardware storage is sold. See the Pricing page for details.

Is there any additional costs for “plugins”?

No. All advanced features are enabled with the standard license. Bear this in mind when comparing our pricing to other vendors who have significant up-charges for features like Fibre Channel support and cloud backup.

What happens if I add additional storage to my system?

The license will no longer be valid. You will need to upgrade the license to the new storage amount. Your data is not affected and the storage services (iSCSI, NFS, SMB, etc) will continue to work but the Zetavault management software will not.

For example, if you go from 16TB to 32TB of storage, you will need to purchase the difference between a 16TB and a 32TB license. There is no need to purchase a new 32TB license. The price per TB gets progressively cheaper the more storage you have.

You should upgrade your license before adding new storage to your system.

How long does the license last?

The license is perpetual and does not expire. It is not an annual license. All updates to version 3.x are provided at no additional charge.

The next major version of the software (version 4) of the software will be subject to an charge should you wish to upgrade. The upgrade price for V4 will be discounted by 50% for V3 customers. We don’t expect V4 until at least 2018.

How long does technical support last?

Technical support is perpetual. It does not expire.

Storage Support

What storage protocols are supported?

For block based SAN storage, Zetavault supports iSCSI, iSER, SRP, Fibre Channel, FCoE and InfiniBand.

For file based NAS storage, Zetavault supports NFS, SMB and FTP.

Storage protocols can be run in any combination on the same box. This is what is known as “unified storage”.

What storage connectivity is supported?

Zetavault supports Ethernet, Fibre Channel and InfiniBand networks.

What Ethernet connectivity is supported?

1, 10, 40, 50 and 100 Gbit Ethernet.

What Fibre Channel connectivity is supported?

Up to 32 Gbit. Only Qlogic adapters are supported at the target side.

What InfiniBand connectivity is supported?

Anything up to 100 Gbit (EDR). All Mellanox, Intel and Qlogic adapters are supported.

High Availability

Is there a high availability option?

Yes. The Cluster edition enables the creation of scalable and high availability storage clusters.

See the High Availability page for more details.

How does the high availability option work?

It requires a minimum of 2 storage nodes.

You can run HA on 2 storage nodes, or you can scale beyond 2 storage nodes to entire racks of storage. Everything is managed from one system.

You can use “head” controller nodes that don't have internal storage or you can use the storage nodes as the controllers.

Other

How is the software managed?

Through a web based application. The application supports PCs, phones and tablets.

We use standard HTML, CSS and Javascript with no fancy extensions or flash.

How is the software updated?

The software is updated through the Internet. Software updates to the management packages do not affect the services running on the system and do not require a system reboot.

Only kernel updates require a system reboot but that can be postponed to when the reboot is convenient.

Is the ZFS FUSE based?

No. The ZFS is kernel based. This is what is known as “native”.

Are there any community forums?

We no not run any forums ourselves. There is plenty of community activity in the ZFS on Linux mailing lists.

See https://github.com/zfsonlinux/zfs/wiki/Mailing-Lists for details.

Is Zetavault open source?

The underlying Linux operating system and the OpenZFS storage technology is open source. The Zetavault specific management software is not open source.

What languages are supported?

At present, only English is supported.

Is there a licensing issue with ZFS on Linux?

No. There are no license issues when using or distributing ZFS on Linux.
