Help me design our network
Rather than starting few new threads in different categories I have decided to include everything in one. If this is not the right category, mods please move it to the right one.
I have started working in a high school as ICT Administrator couple of months ago. We are located in Victoria, Australia. First of all, I would explain briefly what our network is like at the moment. We have two separate networks(two domains) for students and staff. They are not connected to each other and both of them are flat networks with unmanaged switches. We have four physical servers on the staff network and three on the student network based on Windows Server 2000 to 2008. There are 50 staff each with a school provided laptop or desktop. There are close to 300 students and about 250 devices which are a mixture of desktops, laptops and tablets. The client machines mainly have Windows xp or Windows 7 on them. At the moment our usage is pretty basic, both staff and students mainly use it for internet browsing and Office and some other applications.
Now we are planning to implement few new technologies to improve the service and quality of education. The current infrastructure is definitely not suitable for things like BYOD and LMS which we want to implement. So we have decided to rebuild our network with new servers, switches and upgrade all the servers and clients to latest OS. As I am the one who is mainly responsible for this, I thought of asking other admins here and gain knowledge from their experience. I come here quite a bit whenever I need to do research on something or if I am stuck and I have almost always found a solution.
Now I have done some research and planning so would like other’s views on these:
2X Servers- Dell Poweredge Rack Servers R720/R720xd or equivalent
Server OS- Windows Server 2012
Client OS- Windows 8
Hypervisor- VMWare Vsphere Essentials Plus Kit
Firewall/Filtering- Smoothwall/Sonicwall/endian/untangle/Bloxx (I am aware smoothwall is everyone’s favourite)
Backup- Veeam/unitrends or something similar
Classroom Management System- Lanschool/abtutor
UC- Lync Server 2013
I might have missed a few things here and there so please let me know about those. Also I am wondering if I can go somewhere to find some network diagrams and configurations which will make my job much easier. I would also like to know how many lans people recommend having and for what. I would like to use existing unmanaged switches for student computers as they will be phased out once BYOD is implemented.
It would be great if someone can tell me how much they paid for these software and hardware so that I can get an idea. I am aware that the prices vary based on configuration and other factors. If someone else works in a similar size school, can you please tell me what you are using and would you be able to share your network topology.
There are a lot of other questions I want to ask but do not want to make my post longer.
Thanks in advance.
