Introduction
The Tranzman appliance is designed for seamless migration between different backup domains.
It is available as both an ISO image and an OVA template.
- The virtual appliance is recommended for same-vendor transitions where connectivity to tape media or large disk volumes (above 2TB) is not required.
- The OVA template supports environments with up to two million images without modifications. For environments exceeding this limit, an additional 2GB of RAM per 500K images is recommended.
- A single Tranzman appliance can manage multiple environments, but proper sizing considerations should be applied.
Note: To determine the optimal appliance sizing, it is recommended to use Tranzman Recorder, which validates the environment and catalog sizing.
RAM Requirements
| Use Case | RAM Size (Minimum Recommended) |
|---|---|
| Using the appliance for assessments | Minimum 4GB |
| Migrating Same Vendor | Minimum 8GB |
| Migrating Cross Vendor | Minimum 8GB |
 | Additional 1GB of RAM is required for every tape drive connected to the Appliance |
CPU Requirements
| Use Case | CPU Core (Minimum Recommended) |
|---|---|
| Migrating Same Vendor | Minimum 4-core Intel CPU |
| Migrating Cross Vendor | Minimum 8-core Intel CPU |
| Additional 1 core required per tape drive connected to the appliance. Only Intel processors are tested and supported. |
Network Requirements
| Use Case | Network Speed (Minimum Recommended) |
|---|---|
| Migrating Same Vendor & Recovery on Demand | 1Gbps connection |
| Migrating Cross Vendor | 10Gbps connection |
| If multiple links are used, aggregation is required for maximum throughput. Additional connections may be needed for multiple tape drives. |
Ports Requirement
The appliance requires network communication. If an internal firewall is present, the following connections must be allowed to ensure proper functionality.

Storage Requirement
- Minimum 3GB local disk for OS installation.
- Local/SAN attached disks are needed for temporary staging of converted images based on recovery volume requirements.
To correctly size the volumes, it is recommended to use Tranzman Recorder and Stone Ram Consulting Services.
| Use Case | Requirement (Guideline Only) |
|---|---|
| For Assessment | Additional 20GB disk |
| Same Vendor Migration | Additional disk(s) of Minimum ((2.5 * Catalog Size) + (2 * Total Memory)) |
| Cross Vendor Migration | Additional disk(s) of Minimum ((2.5 * Catalog Size) + (2 * Total Memory) + Largest of either:
