Depending on which services shall be used in which range of performance, the PC performance has to taken into account.
|
The following specifications refer to the application of an ISDN-board or V-CAPI. When applying an H.323 Connecting Module, you will need additional memory:
80 MB + 10 MB per channel
|
Basic Installation
Contains:
- ixi-Framework
- ixi-UMS Kernel
|
- one ixi-UMS Connector
- ixi-UMS Voice-Mail Server
|
Needed:
| · | At large installations (more than 400 users), space should be included for the with 0,5 MB per voice-mailbox announcement. |
| · | Processor at installations with up to 4 channels: 1,5 GHz |
| · | The required main memory per channel, depending on the services, has to be added: |
Service
|
Main Memory
|
Fax / SMS /Voice
|
20 MB / Channel
|
TTS
|
15 MB / Channel
|
OCR
|
5 MB / Channel
|
Render Connector
|
50 MB
|
SMTP-based Connectors
|
12 MB / Number
|
FAPI / FapiTxT-Connector
|
10 MB / Instance
|
SAP R/3 -Connector
|
25 MB / Instance
|
For a basic installation with ixi-UMS Fax and Voice as well as an ixi-UMS Connector on a Windows Server 2008 R2, a "Hardware" (parameter for virtual machines) should be deployed with the following parameters at least:
Hard Disk: 40 GB
Prozessor: 2 GHz
Free main Memory: 2 GB
|
You have to take into account here, of course, that the applications (e.g. Word) are accessed for the rendering and need an appropriate main memory.
A one-page Word-document, for example, needs approx. 30 MB main memory in order to opened and printed with Word 2007.
|
Basic Recommendation
| · | ixi-UMS and Estos UCServer can be installed together on one machine. |
| · | It is recommendable, however, to install the modules ixi-UMS Kernel, ixi-UMS Connector and/or UCServer on a machine separate from the messaging system. |
Advantage:
| o | No influence on the messaging system when maintaining the ixi-UMS Server (e.g. ISDN-board driver update) or CTI Server |
| o | No software installation on the messaging server |
| o | When maintaining the messaging server, the ixi-UMS Server is fully ready to send and receive (processing of the queues) |
