5.8.2 Resource Bottlenecks Caused by Virus Scanners
If there are several VMs running on a particular ESX server and there are any virus scanners installed on
these VMs, these virus scanners should be set up so that they wouldn‟t start their virus check cycle at the
same time. If so, they may cause substantial bottleneck on system resources, especially CPU and disk
bandwidth, and as a consequence, fax transmission error rate may increase dramatically during such a
period of time.
5.9 Test: 150 Fax Channels
KCS was successfully tested with 150 fax channels on virtual computers in a tandem configuration.
Hardware:
Host system 1 (primary master and status agent): HP Proliant DL380 G7, CPU Intel Xeon E5645 2.4
GHz, 2 processor sockets with 6 cores each, 12 GB RAM, HP Smart Array P410i Controller, Raid 1+0
Host system 2 (secondary master): HP Proliant DL380 G7, CPU Intel Xeon X5650 2.665 GHz, 2
processor sockets with 6 cores each, 24 GB RAM, HP Smart Array P410i Controller, Raid 1+0
Virtualization settings:
Host software: ESXI 5.5.0, free license
Primary master virtual machine: using 4 processor cores, speed not limited
Secondary master virtual machine: using 4 processor cores, speed limited to 2,4 GHz
Windows Server 2008 R2 Enterprise x64
Test work flow:
Test messages consisting of an XML body in TC/XML format with linked PDF attachments are
automatically created by a test script and put into the network share polled by the TC/LINK-XML
instances.
TC/LINK-XML takes the messages from the network share, adds a TCI alternative for the PDF
attachments and puts them into TCOSS, to be sent out as faxes.
TCOSS sends the messages on the 75 outbound fax lines, which are connected to the 75 inbound fax
lines, creating back-reception documents and notifications.
The notifications are processed by TC/LINK- XML and put into a “NOTIF” directory on the network share
(to be deleted by a script)
The received faxes are routed to a queue polled by the KCS Capture Connector via TWS, transferred to
Kofax Capture and marked completed in TCOSS.
The TCOSS file structure size is 100 GB, with 4 million file entries. There are 50,000 mail entries and
220,000 address book entries.
