3 Performance Considerations

This chapter provides performance data and considerations for capturing device configuration archives in Oracle Communications Configuration Management.

Device Configuration Archives

This section outlines the archiving rates for small, medium and large scale deployments.

Small-scale Deployment

In a small-scale deployment, the time it takes to perform scheduled archives is as follows:

• PE device — can be archived at a rate of one per minute

• CE device — can be archived at a rate of 50 per minute

Example

The following example shows the approximate time it takes to archive an average small-scale deployment:

• 10 PE devices = 10 minutes to archive

• 990 CE devices = 20 minutes to archive

  Total = 30 minute archive

Medium-scale Deployment

In a medium-scale deployment, the time it takes to perform scheduled archives is as follows:

• PE device — can be archived at a rate of two per minute

• CE device — can be archived at a rate of 300 per minute

Example

The following example shows the approximate time it takes to archive an average medium-scale deployment:

• 50 PE devices = 25 minutes to archive

• 4,950 CE devices = 17 minutes to archive

  Total = 42 minute archive

Large-scale Deployment

In a large-scale deployment, the time it takes to perform scheduled archives is as follows:

• PE device: can be archived at a rate of two per minute

• CE device: can be archived at a rate of 300 per minute

Example

The following example shows the approximate time it takes to archive an average large-scale deployment:

• 200 PE devices:

  • with two CPUs = 100 minutes to archive

  • with four CPUs = 50 minutes to archive

• 19,800 CE devices:

  • with two CPUs = 66 minutes to archive

  • with four CPUs = 33 minutes to archive

  Total

  • for devices with two CPUs = 166 minute archive (2 hours, 46 minutes)

  • for devices with four CPUs = 83 minute archive (1 hour, 23 minutes)

Tuning

To decrease the time it takes to archive device configurations, you can increase the number of threads in the Network Processor. This mainly applies to large-scale deployments.
