Minimum requirements to deploy ZVA appliances are:

Minimum of 12GB of disk space allocation. How to dimension ZVAs properly?
At least, 2 network interfaces. It’s a good idea to maintain the maintenance network interface independent from the services network interface. If the cluster is configured, it’s recommended to create another independent NIC to reduce latency.
It’s recommended to configure dedicated cores in the hypervisor.
Follow the good practices when configuring a cluster service. Latency and clock skew could cause important effects on virtual platforms.

The software included in the ZVA Enterprise Edition is delivered under the terms of GNU Affero General Public License v3.

The ZVA products licensing model is related and associated with the number of instances deployed per virtual template, so it’s needed as many appliances as deployments required. Resources like CPU, memory or throughput allocated per virtual machine are not relevant to the licensing model.

If a single node is required, only it’s needed to acquire one appliance license. If a cluster LB service is required, two appliance licenses are needed.

When acquiring an appliance, a product version certificate is obtained and we can provide every kind of hypervisor for such product version. Each appliance could be updated with the incremental software releases that we provide with a valid Support Plan in form of install package, but a redeployment of any product version upgrade requires acquiring a certificate upgrade for such a new version.

On the other hand, a redeployment during the appliance lifetime is supported meanwhile the hostname remains the same. In a similar way, an appliance certificate could be reissued to change the hostname of the appliance if there isn’t any associated redeployment of such.

How does the evaluation work?

The evaluation of this product is free of charge and it allows to deploy, create, and use the real product for one month by default. Extensions of this period could be requested to the Sales Team through the contact form. During the evaluation period, pre-sales support is available.

Once the decision of purchase is made, it’ll be enough to issue a definitive activation certificate without the need for deploying the appliance again.

How to migrate from Community to Enterprise edition?

In order to migrate from Community to Enterprise Edition, it is required to redeploy the appliance, since the operating system is optimized for networking operations, and then a configuration migration process needs to be applied. Our technical team will assist to automate this migration from Community to Enterprise when required.

How many licenses do you need to build a cluster?

In order to build a cluster and obtain HA, it’s needed to acquire two licenses.

ZEVENET cluster is a stateful cluster which means that once the primary node is detected as down, the second one takes the control but the clients don’t experience any disruption. In order to achieve that, the second node is constantly synchronizing configurations, automatic processes, connections, user sessions, etc. So both nodes require to be online at every moment. That also permits that the switch between nodes is quite fast.

Is support included with the appliance?

The support service is not included with the appliance and it should be acquired a part of the product in order to get updates, security advisories and patches, hotfixes, development proposals, and assistance from our specialized Support Team. We can provide three different support plans for every application requirement, from Subscription to 24×7 support services.
