1. Scope
This article provides an overview of Datto's SIRIS 3 Imager tool and provides links to other sources of information about this tool.
2. Background
SIRIS 3 Imager is a USB stick that contains the necessary code to convert any capable computer into a Datto SIRIS. Converted devices have a model number starting with SC (SIRIS Conversion) or I (Imaged).
3. Requirements
Disable any hardware RAID on the system to be imaged. If possible, enable HBA mode (sometimes called IT mode), or set each drive to RAID 0. Hardware RAID is not supported for monitoring drive health.
In order to successfully run the SIRIS operating system, the computer must meet the following requirements:
- BIOS that is capable of USB boot
- Two NIC cards with internet connectivity
- Dual Core 64-bit processor
- HDD with at least 250GB free space for the Datto OS. Total hard drive space should not exceed 1 TB.
- Two or more 7200 RPM HDDs for the storage array
- Minimum amount of RAM as determined by local storage capacity
- Servers that use external SAN configurations are not supported.

| I60000 | 2 x 2.3 GHz | 2 x 12 | 256 GB | 13 x 6TB (RAID 6) (60 TB before zfs) - SIRIS 3/NAS 3 Enterprise 60000 |
This chart shows recommended amounts of CPU, CPU cores, and RAM to take full advantage of multiple virtualizations for a disaster recovery scenario. However, the system can perform with less power. Higher RAM and CPU power increases the speed and efficiency of backups and virtualizations.
We support all Ubuntu Server Certified Hardware that meets the above requirements.
