that it could provide. I believe we’ve gotten great value
for money,” he added.
SET now hosts about 100-150 servers and expects a
20 percent increase in the next six to12 months, using
the new data centre infrastructure. Even so, SET is
confident that the growth in users and servers will be
handled smoothly. The same infrastructure will also be
used for additional services, such as IP Telephony and
wireless networks. “We have in place plans for using
IP Telephony and wireless networks in the secondary
site. We have also deployed wireless in the primary
site, using it for both public work areas and also for
internal use,” he said.
The existing primary site uses PBX for telephony, and
remote users log into the network using RAS.

underway to implement the Cisco mobile office
