Release R7 is an enhancement release to the previous Zadara R5 release which includes scalability, security, usability improvements, new features and bug fixes.

The following section will breakdown the additions and updates to the Zadara Compute Cloud platform (zCompute).

R7 (V21.4.0) - Key Enhancements

VPSA based VM and Volume DR

zCompute can now orchestrate the protection and restore of individual Instances and Volumes between two zCompute systems connected to different VPSAs. The data transfer is done using VPSA volume mirroring between sites, and zCompute has enhanced the protection plans capability to support setting of mirroring on the volumes and to place the required metadata for restoration on an NFS share on the destination VPSA.

Self service password reset

Users can reset their passwords directly from the login page using the “Forgot your password?”.

Added support for virtual network appliances within a VPC

Some virtual network appliances are either a virtual firewall that requires full control of the traffic coming in/out of the interface, or may be a VPN appliance that has extra IPs representing the client endpoints.

To support the above, there are now two new settings:

  1. Enable/Disable Source/Dest Check - which only controls the L3 IP check. Item 3 above. (This operation can be done by any tenant member)

  2. Enable/Disable Port security. This one can only be set by MSP or Cloud admins.

The options were added to the security groups settings of the interface


Improve VNC console security

Starting of R7 version, users must explicitly allow Zadara administrators or MSP administrators to connect to the VM VNC, otherwise only users from the same project can access the VM VNC.

Auto-populate instance name as a DNS record

When creating a new instance from the Management user interface, the DNS name field in the VM creation wizard will auto populate the VM name as the DNS name.

VPC deletion wizard

A VPC is a construct with many sub resources and/or attached resources. A VPC deletion wizard was added to easily delete a VPC and it’s related resources as long as there are no running workloads in the VPC.

Allow user to set VPC as default VPC

The user is now able to change the default VPC by setting a new VPC as the default one.

R3 (V5.5.3) - Key Enhancements

Quick start button and screens

Look for the quick start button on the main navigation bar


It will easily guide you via the most common tasks such as creating VM instances, attaching storage volumes, etc…


New VPC creation wizard

A wizard was added to assist you with creating the 3 common topologies of VPCs with private or public subnets


The Wizard can activated from the Quick Start and from the VPCs pane


Elastic Network Interfaces

A new screen was added to manage Network Interfaces. Network interfaces may be attached and detached from an instance and may even move between instances or be a route target. Until now, you could only create it implicitly when connecting an instance to a subnet. Now it has its own screen that exposes the full functionality.

A user can now Create/attach/detach/add security groups and update the name of any network interface.



A VM with client tools available on the marketplaces Toolbox v5.5.0. The images contain the Symp CLI, AWS CLI, Python 2.7, Boto3 and Terraform. The instance should be created with an SSH key pair.

  • NK-386 - Added Storage Pool update mechanism
