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

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 is setup (see www.cisco.com/go/ucsrnd for details).
Active Call processing nodes: 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
 | Note: | The Unified Communications Manager data is based on ~93-98% sequential writes. |
- 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 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 |

| 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.

| Upgrade | 0 | 320.006 | 3.691 | | 0 | 105.001 | 10.341 | Major upgrade |
| AVERAGE OPERATIONS | ||||||||
