Hardware and Software Requirements

AP ENPS is the most advanced multiplatform news production software available today. The hardware and software required to run AP ENPS is all off-the-shelf, giving you choices when it comes to building a system that best fits the needs of your organization. 

We strongly encourage a technical consultation with our support team before purchasing the components of your system for AP ENPS. Please contact us to arrange a time that works for you. 

The physical and virtual server requirements in this guide will vary based on the number of users at your site and other factors.  You may also need additional servers as your organization grows.  All hardware must have the appropriate drivers.

If you have any questions about the hardware and software requirements, please contact us.

Server Requirements

The following table lists server requirements. These requirements apply to your ENPS Primary and Buddy Servers and the servers that will be running NOMWebService: 

Note: Performance and speed will be enhanced if your computer’s processor, memory, and available disk space exceed the minimum reqhttp://www.enps.com/admin/general_content-section_pages.phpuirements.

  Minimum Server Requirements
Recommended Server Specification
CPU Each server must have at least two Intel Xeon 2 GHz processors. Having a dualcore processor does not take the place of multi-processors. At least two Intel Xeon processor E5-2400 or E5-2400 v2 or better.
RAM 32-bit servers require 4 GB
64-bit servers require a minimum of 8 GB 64-bit servers: 16 GB or more
Hard Disk Storage

Two (2) RAIDs are required for ENPS server operations in any environment.

Common configurations include: RAID-5: 3 x 60 GB 10k RPM+ SCSI or SAS drives or RAID-1: 2 x 120 GB 10k RPM+ SCSI or SAS drives.

This must be a hardware-based RAID; software based RAIDs will not work.

For configuration questions or if you would like to set up a different RAID configuration than what is listed, please refer to the Hard Drives section below or contact ENPS Support.
32-bit Two (2) RAIDs, each of which should yield a minimum of 120GB of space, including the operating system. For more details on recommended RAID configurations, please see the Hard Drives section below.
64-bit Two (2) RAIDs, each of which should yield a minimum of 120GB of space, including the operating system. Three (3) RAIDs – one for the operating system, one for the Index partition, and one for the remaining ENPS partitions.

For more details on recommended RAID configurations, please see the Hard Drives section below.
Operating System Windows Server 2008 (32-bit), Windows Server 2008 (32-bit) or Windows Server 2008 R2 (64-bit), Windows Server 2012 (64-bit), and Windows Server 2012 R2 (64-bit).

The operating system you are using must have the latest Microsoft service packs and security patches installed. Microsoft .NET Framework 4.X must be installed.

Wire Ingestion If your server will be ingesting AP WebFeeds or any Social Media feeds, an Internet connection is required. Multi-port serial card such as Comtrol Rocketport or Digi Board with one port for each incoming serial port-based wire feed. PCI or PCI Express connectors for the multi-port serial cards are recommended. USB connectors are not recommended.
Network Interface Card 10/100BASE-T minimum; The card must support TCP/IP in a Windows networking environment. 10/100/1000BASE-T recommended.
Backup System   A network-based or local backup system is strongly recommended.
Additional Software Microsoft Internet Explorer 7.0 or later.

A defragmentation tool with scheduling capabilities is required - Diskeeper Server is recommended.
A tool to provide remote access to server such as Microsoft Windows Remote Desktop or some other 3rd party software (as preferred).

Adobe IFilter 6.0 to index PDF files. This tool is available as a free download from Adobe.

Real-time antivirus software is not recommended. Refer to Antivirus Software Recommendations for more information.

Hard Drives

On 64-bit operating systems, a minimum of 6 hard drives (SCSI, SAS, SSD or similar enterprise-level storage devices) are required for best performance; 8 drives allow for highest availability. 3.5” platter hard drives are preferred as they have been found to provide slightly better performance compared to 2.5” drives. SSD drives have not shown to offer significant performance increases to justify their increased cost at present, although this may change. Sites using virtual servers should maintain the same drive configurations, swapping a virtual hard drive (VHD) for each physical RAID listed below.

Software RAID is not supported or recommended.

Best Performance Configuration for 64-bit systems – 3 RAIDS (min. 6 drives)

RAID 1 RAID 1 RAID 1 or RAID 5 or RAID 10
Operating System (C:) Index (E:) ENPS Work (F:, G:, H:)

Normal, Acceptable Configuration for 64-bit systems – 2 RAIDS (min. 4 drives)

RAID 1 RAID 1 or RAID 5 or RAID 10
Operating System (C:)  Index (E:) ENPS Work (F:, G:, H:)

Recommended for 32-bit systems, Not Recommended for 64-bit systems

RAID 1 RAID 1 or RAID 5 or RAID 10
Operating System (C:) ENPS Work and Index (E:, F:, G:, H:)

Note: The recommendations above mean that sites which have previously run ENPS with only C: (system) and D: (index and ENPS data) drives in the past, should change their drive configurations to include at least 3 drives – system, index and ENPS data – when building 64-bit servers for use with the ENPS client. For acceptable performance, the index should be on its own partition; for optimal performance it should also be on its own RAID array. Having the index and ENPS data on the same partition can slow down access to ENPS data during times of heavy indexer activity.

ENPS Client on a Mac-Based Computer

The full ENPS client application will run on a Mac when combined with the following third party applications: 

* Parallels * VNC
* Fusion * Boot Camp
* Remote Desktop * Windows on Apple Hardware


In these cases, support is provided for the ENPS client as it is run within the Microsoft Windows Operating System. Specific technologies required to bring the Windows Operating System and ENPS client UI to the Apple desktop are provided by third
parties. Third party technologies bring with them specific feature sets. As with Windows System Administrators, Apple System Administrators should be familiar with the Apple OS as well as specific third party applications and features.

A list of recommendations can be provided on how to best configure many of these third party technologies to work with the ENPS client, but direct support is not provided for third party software.

Any Mac workstation that is to be used to host an ENPS client should not only meet the minimum specifications of the software being used to host the environment in which the ENPS client is run, but the resources allocated to that environment should meet or exceed the normal ENPS client minimum specifications.

Virtual Machines

Keep the following requirements in mind before you install an ENPS server on a virtual machine:

  • The Associated Press does not support third party software such as VMWare. You should contact the virtual machine vendor for support issues related to their software.
  • You are solely responsible for meeting the virtual machine's requirements for hardware, networking, wire ingestion, and integration. ENPS servers on virtual machines require the same operating system, memory, storage, and processing power as physical ENPS servers.
  • There should be a minimum of 2 GB of RAM available to the host machine after the virtual machine is mounted.
  • Make sure that anti-virus software on the host machine does not scan virtual machine files. Just like a physical ENPS server, an ENPS server in a virtual machine environment should not run antivirus software with real-time scanning. Refer to Anti-virus Recommendations for more information.
  • Running an ENPS Primary server and its corresponding Buddy server as virtual ENPS servers on the same machine simultaneously is not an acceptable configuration.

Anti-virus Recommendations

The Associated Press recommends against using anti-virus software with real-time scanning on ENPS servers. Doing so may result in the following issues:

  • The anti-virus software may have kernel-level conflicts with Microsoft's Index Server or the Windows Search Service, which the ENPS client uses for its Search functionality.
  • When new material is added to the server it may take significantly longer to add it to the index and therefore will not be available through Search as quickly.
  • The index may be corrupted frequently. If it is corrupted, re-indexing will take significantly longer to complete. The Index Server may attempt to repair itself from a conflict by re-scanning the indexed drives which can significantly degrade
    server speed.
  • Unscheduled Master Merges may occur several times a day. This can also decrease server performance.

These risks can be severe but they do not always occur. If you accept the potential consequences of running anti-virus software on an ENPS server following these steps to reduce the likelihood of encountering problems:

  • Set the anti-virus software to perform scheduled scans instead of real-time scans.
  • If you must do real-time scans exclude the ENPS data drive(s), which are usually D: on a single-partition system and F:, G: and H: on a multi-partition system. Also exclude the ENPS index folder Catalog.WCI.

If you experience frequent Search or indexing problems while running anti-virus software you may need to disable or uninstall the anti-virus software while you troubleshoot.

To reduce your servers' vulnerability to viruses and spyware you should take the following precautions:

  • Keep servers updated with all of the critical updates from Microsoft. AP recommends installing all critical updates from Microsoft right away. You do not need to wait for our approval. Do not install Service Packs until AP has certified their compatibility with AP ENPS. AP will post compatibility notes on its ENPS support board, http://support.enps.com and in release notes provided with each ENPS software update.
