VMware Ready certification

Verba Technologies is a VMware Technology Alliance Partner, and has tested and approved all system components, including the Recording Server and the Media Repository roles, to run on VMware solutions.

 The Verba Recording System is VMware Ready certified: 

VMware instance examples for Verba servers

These are very simple examples for the configuration of VMware instances where your Verba servers are installed:

Verba Media Repository (MR)Verba Recording Server (RS)Verba Express Server (MR+RS combo)

4 vCPU, 8 GB vRAM
Windows Server 2008 R2 x64
>40 GB system disk
>100 GB media disk 

2 vCPU, 4 GB vRAM
Windows Server 2008 R2 x64
>40 GB system disk
>40 GB media disk

4 vCPU, 8 GB vRAM
Windows Server 2008 R2 x64
>40 GB system disk
>100 GB media disk

The passive recording solutions uses a monitored network traffic to record the calls. In default, the vmware virtual interface drops the frames which are not sent to the virtual interface. To prevent this, you need to enable the promiscuous mode on virtual interface which is conneced to the Verba Recording Server. How to configure promiscuous mode on a virtual switch or portgroup in vSphere.

Recommendations for VMware environments

When configuring the VMware platform, the following recommendations apply:

  • For Recording Servers using the passive recording technology, an extra dedicated physical network interface is required on the host machine and needs to be allocated specifically to the virtual machine in order to capture the mirrored network traffic.
  • For the Recording Server components, the minimum CPU and memory resources must be permanently dedicated.
  • The requirements regarding the hard disk performance must be carefully handled, especially for the write intensive Recording Server components.
  • For the Media Repository component, the memory has to be permanently dedicated; the CPU resources can be shared with other virtual machines.
  • It is recommended to use Intel based Nehalem processors (e.g. E5540) to enjoy the hardware assist benefits.
  • It is recommended to enable hyperthreading for optimum CPU performance.
  • It is recommended to use VMware vmxnet3 paravirtualized adapter for optimum network IO.
  • It is recommended to implement storage best practices to reduce the latency such as disk partition alignment, proper RAID configuration, eager zeroed disk, adequate number of spindles etc.

VMware Virtual Machine File System: Technical Overview and Best Practices

The VMware Virtual Machine File System (VMFS) is a high performance cluster file system that allows virtualization to scale beyond the boundaries of a single system. Designed, constructed, and optimized for the virtual server environment, VMFS increases resource utilization by providing multiple virtual machines with shared access to a consolidated pool of clustered storage. And VMFS provides the foundation for virtualization spanning multiple servers, enabling services such as VMware Vmotion, Distributed Resource Scheduler, and VMware High Availability.
