Prognosis Virtual Server CPU Best Practices

For best performance of a virtual server to be used for Prognosis, be sure to configure the CPU as it would exist on a physical server. Prognosis recommends an Intel Xeon 3450 Quad-Core processor 2.66GHz. On the virtual server CPU settings, you would configure 1 physical CPU or socket and then configure the 4 cores to make up the quad core. This is more efficient than configuring 4 separate sockets of 1 core each. the multi-core setting processes threads simultaneously rather than sequentially and is more efficient with a multi-threaded application like Prognosis.

Re: Prognosis Virtual Server CPU Best Practices

I thought it was 2 sockets, 4 CPU and up to 200GB of space?

Re: Prognosis Virtual Server CPU Best Practices

Hi Tonia,

we tested that internally and if I recall correctly one socket was the most efficient setting. Disk size does depend on what number of systems you monitor and what load is comming in (e.g. how many calls). Also if there was a change to the default data retention time it will have an impact on the disk space needed.

HEre the extract from the documentation:

After installation, the Prognosis server requires at least the following amount of disk space for normal operations:
- Windows server......................2.0 GB
In addition, the Prognosis server requires the following amount of space for the storage of historical data.
- Common UC databases................34.0 GB
Plus, the maximum database size for each vendor type is:
- Alcatel-Lucent OmniPCX:.............1.5 GB
- Avaya Aura Communication Manager:..65.5 GB
- Avaya Communication Server 1000:....2.2 GB
- Avaya IP Office:....................4.6 GB
- Avaya Modular Messaging:............7.1 GB
- Avaya System/Session Manager:.......1.0 GB
- Contact Center:.....................1.0 GB
- Cisco Emergency Responder (CER):....1.0 GB
- Cisco UCM 5+ (per cluster):.........7.0 GB
- Cisco Express Suite:................1.0 GB
- Cisco UCS B-Series: ................3.0 GB
- Cisco UCS C-Series:.................1.0 GB
- Cisco UCCX:.........................1.0 GB
- Cisco Unified Presence:.............1.0 GB
- Cisco Unity Connection:.............1.0 GB
- Microsoft Skype for Business:......87.0 GB
- Session Border Controllers:........ 1.0 GB

UPGRADE: Twice the recommended minimum disk space is required for a backup and restore of these databases during an upgrade to a later Prognosis version.
