Meet the minimum requirements to ensure a successful installation of Content Rendering Engine (CRE).

Requirement Notes

VM or Physical Server (64-bit)

Co-locate CRE on a separate server in the same data-center or network as Remote File Storage (RFS) for maximum performance.

Sizing Recommendations

Sizing estimates for devices may vary based on concurrent usage. If CPU, RAM, or I/O utilization approaches 70-80%, consider adding more resources or servers.

# of Devices CPU Cores RAM (GB) Disk Space (GB)
1-1000

4+

4-8 20+
1,000-5,000

8-16 CPU cores

OR

4 CPU cores w/4 load-balanced servers

8-16  
5,000-25,000

16 CPU cores w/4 load-balanced servers OR

8 CPU cores w/8 load-balanced servers

16-32  
25,000+ 8-16 CPU cores w/8-16+ load-balanced servers 32+  

General Requirements

Requirements Notes

Internally registered DNS record

Register the Endpoint server.

Externally registered DNS record

Register the Endpoint server.

SSL Certificate from trusted third party with subject name of server hostname

Requires a PKCS12 (.pfx) format and the trust of all device types in use. Keep in mind:

  • Android does not natively trust all Comodo certificates.
  • PKCS12 (.pfx) format includes the server certificate, private key, root chain, and password protection.
Remote File Storage set up and configured

Because CRE integrates with RFS for Linux, you must install RFS for Linux before proceeding with CRE installation.

Software Requirements

Requirement Notes

SSH access to Linux Servers and an admin account with full write permissions.

Root permissions, or sudo access with the same privileges as root required. Once installation completes, you can put restrictions into place for these account types.

yum Enabled

Enable to allow the installer to request and install any missing prerequisites.

CentOS 7.x

SUSE 12.x

RHEL 7.x

UI-less recommended.

Basic infrastructure type recommended.

Remove Java from server prior to install. Java packaged with installer.

Network Requirements
