The Draco SIRA CPU enables the seamless integration of virtual machines into KVM systems.

Product Information

Draco SIRA CPU (Series 488)

The Draco SIRA CPU (Secure IP Remote Access) combines the functionality of a thin client and a KVM extender (transmitter). This space-saving solution is fully compatible with the Draco vario extender and the Draco enterprise and compact matrix switch series.

The IP module provides seamless KVM connectivity to an IP infrastructure. It supports RDP, RemoteFX, SSH, VNC and HTML5 protocols (access via kiosk mode). Further remote protocols will be incorporated in future and can be made available on demand. A single Draco SIRA CPU can host up to 8 simultaneous sessions.

KVM meets VDI
Using diverse remote access protocols the SIRA CPU provides KVM access from the KVM system to virtual machines and webbased interfaces in the same manner as accessing real PCs.

The Draco tera KVM matrix system enables the parallel operations of several Draco SIRA CPUs – even with different network connections. It isolates the networks from each other like a firewall and thus allows secure access to „private cloud“ and „public cloud“ systems from one workstation.

RDP and the benefits of KVM
The KVM infrastructure adds extensive flexibility to a RDP session. RDP sessions can now be shared amongst multiple users, delivering better collaboration and control room solutions.
Immediate access Immediate access to real PCs and virtual machines is achieved through permanent connection. Switching between the two types occurs instantaneously, with no disruption or inconvenience to the users.

Single Sign On
For ease of operation, the system can be configured to support SSO. Single stage user identification is all that is required, either locally or via AD. User credentials are stored for future connection setup.


The Draco vario Remote IP CPU is still available as a starter model with basic functionality.
