This page helps you to configure the server for your Verba Ethical Wall/IM 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:

Ethical Wall

For Cisco deployments, both the Media Repository and the Compliance (Recording) Servers are needed.
For Skype for Business (Lync) deployments only the Media Repository is needed.

IM Recording

Both the Media Repository and the Compliance Servers are needed.

Server Role



Media Repository (MR)

Compliance Server (CS)

(Recording Server)

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

Quad-core Intel Xeon 2.4 GHz or higher with Hyperthreading

rule of thumb:

  • 100 messages per second per core, but minimum of 2 cores for Compliance Servers
  • 1 Media Repository needed per 500 simultaneous web user sessions, with a minimum of 2 cores
  • Performance is highly dependent on the actual traffic
Memory8 GB4GB8GB
Hard disk

System disk - 80 GB or more

Network1x Gigabit Ethernet1x Gigabit Ethernet
(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 2012 R2
Microsoft Windows Server 2016 
Microsoft Windows Server 2019

Standard Edition, latest service packs installed

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


VMware recommended, see Virtualization.

IMPORTANT! Hyper-V is currently NOT supported for passive (SPAN port-based) recorders.

AntivirusMake sure your Antivirus software does not scan database, media and log folders.
