Signiant SDCX Server System Requirements

This guide outlines the system requirements and firewall configuration needed to install and use the Signiant SDCX Server in your organization.

The Signiant SDCX Server, previously known as the Media Shuttle Storage Server, is software that must be installed at any on-premises location that will be used with either Jet or Media Shuttle. The SDCX Server connects your storage to Signiant’s SaaS platform, enabling file transfers using either Signiant product. A single deployment can support both products and the software can run on more than one server for high volume usage and redundancy.

There is no charge to download and install Signiant SDCX Server software. Its use is included in annual SaaS subscriptions for Jet and Media Shuttle.

Signiant SDCX Server software provides an endpoint for Jet transfers and Media Shuttle on-premises storage, such as a local disk, NAS, or SAN.

Network Requirements

The following ports are required by Signiant SDCX Server to perform transfers:

ProtocolDirectionPort RangeChange TypeDescription
TCPInbound49221Network FirewallUsed for file transfer
UDPBidirectional49221-49421Network FirewallUsed for file transfer
TCPBidirectional50221Network FirewallUsed for file transfer
TCPBidirectional50222Network FirewallUsed for relay transfers
TCPOutbound443Network FirewallUsed to connect to cloud services:
Storage server to Amazon EC2 IP Ranges
Storage server to Amazon CloudFront IP Ranges
Note: Port 443 requires unrestricted outbound access to the Internet. SDCX server versions 3.5 or earlier require TCP Port 80 to accept bidirectional traffic.

Note: In addition to network setup on the firewall, you must also configure Windows Firewall on Windows, or iptables on Linux.

Local Port Requirements

Signiant SDCX Servers use a range of local ports for monitoring, control, and data transfer functions. No other software can use these ports on your server when using Jet.

The following ports must not be used by any other local processes:

ProtocolDirectionPort RangeChange TypeDescription
HTTPSLocal8443Local ServerLocal connection to storage server
TCPLocal8888Local ServerLocal connection to storage server
