System Requirements
Virtualization Platforms
- VMware vSphere: Version 7.0 ESX host or higher is required.
- OpenSUSE Leap 16.0: Appliance is built on OpenSUSE Leap 16.0 operating system.
ESXi Host Hardware Requirements
The ESXi host running the Superna Disaster Recovery Edition virtual appliance must meet the following minimum hardware requirements:
- CPU: Minimum 2 physical CPU sockets with processors ≥ 2.0 GHz per core
- Disk latency: Less than 10 ms average latency
- Storage type: Enterprise-grade storage (SSD or high-performance SAN/NAS recommended)
Poor disk performance or high latency can impact disaster recovery operations, failover readiness checks, and overall system performance.
VMware vCenter Deployment
vCenter 7 and vCenter 8 are supported for deployment.
System Resources
- CPU: 4 vCPUs
- Memory: 16 GB RAM (Memory may need to be upgraded based on scalability requirements. Refer to the scalability table for more information.)
- Disk Space:
- Operating System Partition: 30 GB
- Additional Disk Space: 80 GB
- Total Disk Size in VMware: 110 GB
Network Requirements
- Latency: The latency between the administration PC and the Eyeglass VM GUI must be less than 15 ms (measured by ping).
Authentication and User Management
- Active Directory (AD) Authentication: An AD authentication provider must be available for Role-Based Access Control (RBAC) and SID-to-user resolution API requirements.
Browser Requirements
- Supported Browser: Google Chrome is required. The browser must support WebSockets.
- Unsupported Browsers: Internet Explorer is not supported.
- Cookie Settings: Third-party cookies must not be disabled, as they are required for authentication sessions and file downloads.
Port Requirements
The following network ports must be open for proper operation of Superna Disaster Recovery Edition 4.3.0.
| Port | Protocol | Source → Destination | Description |
|---|---|---|---|
| DNS 53 | UDP | Appliance → DNS Server | Required for DNS resolution used by system services and validation checks. |
| TLS 443 | TCP TLS 1.2 | Appliance → Internet | Required for remote monitoring, support log uploads (Phone Home), and update services. |
| NTP 123 | UDP | Appliance → NTP Server | Required for time synchronization. The appliance must use the same NTP source as the environment. Disable VMware host VM time synchronization. |
| SMTP 25 | TCP | Appliance → Mail Server | Required for sending system alert and notification emails. |
| HTTP 80 | TCP | Appliance → OpenSUSE repositories | Required to download operating system updates and security patches. |
| HTTPS 443 | TCP TLS 1.2 | Admin PC → Appliance | Required to access the appliance web user interface. |
| HTTP 80 (redirect) | TCP | Admin PC → Appliance | Redirects HTTP requests to secure HTTPS access. No services run on port 80. |
| SSH 22 | TCP | Admin PC → Appliance | Required for secure shell administrative access. |
| SMB 445 | TCP | Appliance → Domain Controller(s) | Required for Active Directory authentication and role-based access control via Domain Controllers. |

| Arrays Added to the Appliance | Supports 4 arrays with 32 GB RAM Supports 4 - 8 arrays with 64 GB RAM Supports > 10 arrays with 84 GB RAM | |
| Concurrent Administrators (3 or more) | Adds 8 GB RAM to the above requirements for each logged-in administrator using RBAC or not using RBAC |
Each release of the software may adjust memory requirements, and the alarm code (SCA0094) will recommend memory for the supported configuration. The recommendation from Alarm Code SCA0094 takes priority over this documentation.
