Server requirements of all Verba server components

This page helps you to configure the server for your Verba Recording System.
Please note, that Verba Technologies does not sell server hardware, OS and database licenses.

This table outlines typical server sizing and recommended hardware and software configurations:

Server Role



Media Repository (MR)

Recording Server (RS)Both functions on one server
(combined MR and RS)
Server PlatformAny industry standard PC server

Quad core Intel Xeon 2.4 GHz or higher with Hyperthreading

rule of thumb:

  • 1 core needed per 75 simultaneous audio-only calls, but minimum 2 cores for Recording Servers
  • 1 core needed per 150 simultaneous audio-only calls, but minimum 4 cores for Proxy Servers
  • 1 core needed per 50 simultaneous audio-only calls, but minimum 4 cores for combined Recording and Proxy Servers
  • 1 Media Repository needed per 1000 simultaneous web user sessions, with a minimum of 2 cores
  • for video applications calculate with 125 Mbps per core, but minimum 2 cores
  • actual performance is highly dependent on used codecs and resolutions
Memory8 GB4GB8GB
Hard disk

System disk - 80 GB or more

Media disk - Use our Storage Disk Space Calculator tool to size your hard disk capacity.
Contact support at to help you properly size your disks.

Always use redundant disks with RAID and have separate Media and System volumes!

On Recording Servers: at least 2 disks with RAID 1
On Media Repositories: if more than 2 disks are needed you can use RAID 5, otherwise RAID 1.

Network1x Gigabit Ethernet1x Gigabit Ethernet
plus 1x Gigabit Ethernet port if you use passive recording
(if you use a virtual server you need to dedicate
a physical port to the virtual server instance - available on VMware)
Operating system

Microsoft Windows Server 2008 R2
Microsoft Windows Server 2012 R2
Microsoft Windows Server 2016 

Standard Edition, latest service packs installed
Important! We support the English versions of Microsoft server software!


Microsoft SQL Server 2008 R2
Microsoft SQL Server 2012
Microsoft SQL Server 2014
Microsoft SQL Server 2016

Express, Standard or Enterprise Edition, latest service packs installed

Express Edition is bundled for free, recommended up to 1.000.000 calls.
If the Full-Text Search feature is needed, then install SQL Server Express with Advanced Services.
See Select your SQL Server Edition

If you have an existing SQL Server cluster, we recommend using that as Verba database
(in that case 4 GB RAM is enough on the MR and MR+RS servers).


VMware recommended, see Virtualization.

Hyper-V is also fully supported.

AntivirusMake sure your Antivirus software does not scan database, media and log folders.
PowerRedundant Power Supply
UPS recommended

Please note the following:

  • No other apps on the server - Verba Recording System components should be installed on dedicated servers or virtual server instances with no other applications being co-hosted on them.
  • You can contact Verba for server review - You can contact Verba or your system integrator representative for a review before submitting orders for your server.
  • Good backup is essential - A regular (daily) backup procedure of the Verba Recording System server needs to be established to prevent data loss and allow disaster recovery.
  • Contact Verba for video recording planning - For video, telepresence and agent computer screen deployments, pleased contact your Verba Technologies or system integrator representative.

Desktop requirements for Verba Desktop Agent

This component is installed on the PC of the agent whose screen shall be recorded during the phone calls.

Hardware and 3rd party software requirements for Verba Desktop Agent component deployment:

CPUIntel Pentium 4 or later
Memory1 GB
Network10/100/1000 LAN interface card
Operating system

Microsoft Windows XP
Microsoft Windows Vista
Microsoft Windows 7
Microsoft Windows 8


The system can record all resolutions, color depths, multiscreen setups.

The following recommendations help to dramatically lower disk space requirements of the recordings:

  • Use the minimum possible screen resolution that still fulfills software usability requirements
  • Use 16 bit color depth
  • Turn off background picture on the desktop
  • Use a low screen recording rate: 3 frame/sec is typically enough for a proper review

Desktop requirements for standard search and replay workstations
