Server sizing and requirements
- Kiss, Mate

This page provides information for server sizing showing detailed information about server requirements such as CPU, memory, hard disk, virtualization, operating system, etc.
Please note, that Verba does not sell server hardware, OS and database licenses.

Server sizing
This table outlines typical server sizing and recommended hardware and software configurations:
Server Role | Recording Server (RS) | Media Repository / Application Server (MR) | Proxy Server | |
|---|---|---|---|---|
| Server Platform | Industry standard PC servers Physical or virtual | |||
| CPU | Intel Xeon 2.4 GHz or higher Up to 16 CPU cores or vCPUs 2 cores/vCPUs must be "reserved" for the OS, only the rest can be used for application sizing Numbers only applicable when Receive-side scaling (RSS) is enabled in the OS | |||
Refer to Media Recorder sizing for voice, video, screen - application share recording When Recording Director is installed as separate servers:
| Up to 100 user sessions: 2 cores Up to 500 user sessions: 4 cores If SQL Server is installed on the server, additional CPU is required. | Skype for Business: 200 voice calls / core Cisco: 150 voice calls / core 75 video calls / core | ||
| Memory | 8 GB | Up to 100 user sessions: 4 GB Up to 500 user sessions: 8 GB If SQL Server is installed on the server, additional memory is required. | 4 GB | |
| Hard disk | System partition (OS and applications): 80 GB or more Media partition: 80 GB or more, use the Storage Disk Space Calculator tool to size your hard disk capacity Always use redundant disks with RAID and have separate Media and System volumes | |||
| Network | 1x Gigabit Ethernet plus 1x Gigabit Ethernet port if you use passive recording | 1x Gigabit Ethernet | ||
| Operating system | Microsoft Windows Server 2012 R2 Standard Edition, latest service packs installed | |||
| Database | Microsoft SQL Server 2012 Express, Standard or Enterprise Edition, latest service packs installed Express Edition is bundled for free, recommended up to 1.000.000 calls. If you have an existing SQL Server cluster, we recommend using that for the Verba database | |||
| Virtualization | VMware recommended, see Virtualization. Hyper-V is also fully supported. | |||
| Antivirus | Make sure your /wiki/spaces/v93/pages/4388496948. | |||
| Power | Redundant Power Supply UPS recommended | |||
Please note the following:
- No other apps on the server - Verba 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.
- A good backup is essential - A regular (daily) backup procedure of the Verba servers, recorded media files and database 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, please contact your Verba or system integrator representative.

Server sizing for servers with co-located/mixed roles
The different server roles can be installed on a single server when the capacity does not exceed the limitations. When sizing the servers with co-located server roles, each role has to be sized separately and added to the overall capacity. The system allows deploying the following server roles:
| Server Role | Description |
|---|---|
| Media Repository / Application Server and Recording Server (Combo) | Includes all Verba services, except the Filter services running on the Skype for Business servers |
| Recording Server | Includes all recording services, ethical wall capabilities, announcement |
| Media Repository / Application Server | Includes all central applications such as web UI, storage management, licensing, APIs, speech recognition, etc. |
| Media Collector and Proxy Server | Includes the media collector and proxy application |
| Announcement Server | Includes the announcement application |
| Speech Analytics Server | Includes speech recognition applications |
| Skype for Business Filter | Includes the applications running on the Skype For Business Front-End servers |
| Media Collector and Skype for Business Filter | Includes the applications running on the Skype For Business Front-End servers and the media collector and proxy application |
| Desktop Recorder | Includes the screen capture application running the desktop computers |
A single server can have only one of the above roles.
