This spring, the Saanich School District finished a complete overhaul of its computer networks B次元官网网址� one that has drastically reduced its energy consumption, saved cash and won an environmental recognition award for the district.
SD 63 replaced every computer in every school to diskless, or thin clients. Each workstation in each school is now connected to a central server, allowing computers to run on less energy, start up and shut off at set times and receive simultaneous updates.
The changeover reduced the school computersB次元官网网址� energy consumption by about 75 per cent and earned the district an Eco Star award from the Capital Regional District. The model will also afford students access to more up-to-date technology since whenever possible, open source software has been installed on the server in lieu of commercial products.
B次元官网网址淥ften times schools are left with using used computers and then using very old software,B次元官网网址� said Gregg Ferrie, director of information technology. B次元官网网址淭he technology is old and dated. The computers are end-of-life, but (school districts) simply cannot afford to do very much because they donB次元官网网址檛 have a lot of capital dollars.B次元官网网址�
The energy savings from replacing more than 2,500 aging Microsoft Windows-based workstations total more than one gigawatt hour per year, or a roughly $80,000 on the districtB次元官网网址檚 B.C. Hydro bill. The energy savings from desktop computers alone are enough to fully power two middle schools for the year.
B次元官网网址淚tB次元官网网址檚 a whole new approach at looking at technology,B次元官网网址� Ferrie said.
A typical school like StellyB次元官网网址檚 secondary school has about 300 computers connected to the server. The IT department isnB次元官网网址檛 burdened with updating each one individually when it comes time, rather dealing with the single server alone. Computers are also turned on and off each day via the server, reducing the energy consumption even further.
While there are pros and cons related to the single point of failure, Ferrie said, there is redundancy built into the servers, which are also centrally backed up.
B次元官网网址淟etB次元官网网址檚 say one server did have a catastrophic failure and couldnB次元官网网址檛 come up and none of the work stations worked, we can replace that server very rapidly,B次元官网网址� he said.
The district is also developing Open Student, a student information program based on the same technology. Ferrie hopes Open Student, now being tested at Saanichton elementary school, the current program, BCeSIS.
B次元官网网址淚t was a bad scenario because it was putting old technology in studentsB次元官网网址� hands. If we wanted to put new computers on every studentB次元官网网址檚 desk it would cost millions of dollars because they have a relatively short life span. Districts just donB次元官网网址檛 have the money to do that.B次元官网网址�
