This page illustrates IOPS under various conditions for Unified Communications applications. This area is under construction. Check back frequently for updates.

Contents

Unified Communications Manager

This section provides the IOPS data for a Cisco Unified Communications Manager system under load. These values are per active VM OVA. Which VM OVAs are active, and how many are active simultaneously, depends on how the CUCM cluster nodes are setup with respect to service activation, redundancy groups, etc. (see www.cisco.com/go/ucsrnd for details).

CUCM storage access is on average 93-98% sequential writes with an IO block size of 4 kilobytes.

  • Active call processing: As a reference, the following steady state IOPS were observed at various loads (expressed in Busy Hour Call Attempts):
  • 10K BHCA produces ~ 35 IOPS
  • 25K BHCA produces ~ 50 IOPS
  • 50K BHCA produces ~ 100 IOPS
  • 100K BHCA produces ~ 150 IOPS
  • Software upgrades during business hours generate 800 to 1200 IOPS in addition to steady state IOPS.
  • CDR/CMR via CDR Analysis and Reporting (CAR)
    • CUCM sending CDR/CMR to the external billing server does not incur any additional IOPS.
    • Enabling CAR continuous loading results in around 300 IOPS average on the system.
    • Scheduled uploads are around 250 IOPS for Publisher's VM only.
  • Trace collection is 100 IOPS (occurs on all VMs for which tracing is enabled).
  • Nightly backup (usually Publisher's VM only) is 50 IOPS.

Cisco Emergency Responder

100 IOPS is a good typical value to plan around. Otherwise use values for Cisco Unified Communications Manager above (they will be conservatively high).

Cisco Intercompany Media Engine

Use values for Cisco Unified Communications Manager above (they will be conservatively high).

Cisco Unity Connection

Summary of IOPS for Unity Connection

IOPS Type 1vCPU 2vCPU 4vCPU 7vCPU
Avg Total 78.66 129.01 217.89 201.73
Peak Total 760.99 714.06 867.88 773.70
Avg Read 5.90 19.60 45.67 9.53
Peak Read 601.84 469.46 693.21 526.22
Avg Write 72.77 109.40 172.22 192.20
Peak Write 247.14 293.51 371.97 413.50

Unified Presence

The CUP 1000 user OVA generates about 60 IOPS during steady-state. Expect similar peaks as CUCM during backups and upgrades.


Cisco Unified Attendant Consoles

This section provides the IOPS data for Cisco Unified Attendant Consoles (using Enterprise Attendant Console to produce heaviest load). Load test and average operations are represented. These tests use the published OVA template for Cisco Unified Attendant Consoles.
