- You could carry on adding Domain Controllers to your network. This is of course an option if you need the extra processing capacity however if storage is the main reason for expanding the servers on your network then there are several disadvantages to this! Increased Running Costs: by adding more servers the amount of electricity to use will increase. You will need to add in the cost of additional support contracts for the servers you are adding. More Technical Management Time: more servers’ means more time required to manage them. Carrying out the daily or weekly housekeeping tasks; applying software updates, and so on. Increased Complexity: The more servers you have on your network, the more complex it will become and, if something goes wrong, it’s likely to take you longer to troubleshoot and fix the problem. Server Room Capacity: The more servers you have, the more room you will need. If your servers are rack mounted you need to ensure you have enough room in your cabinets and also consider the amount of heat will be generated by the additional servers. Will your air conditioning be able to cope with the amount of additional heat the server(s) will create?

- Reduce Downtime: A shared storage solution can minimise the downtime of any network as there are redundant, multiple paths between the servers and storage. As you can see in the diagram above, the server contains two SAN Ethernet controllers with one controller going to each SAN switch. Should one of the Ethernet controllers fail then there is another path to the SAN. Increase Performance: A SAN can speed up the network by intelligently spreading data across multiple discs avoiding data blockages. Fewer Devices to manage No need to keep adding NAS boxes, Hard Disk Drives and extra storage, it is much easier to manage with a SAN and no need to worry about running out of storage. Utilise Space More Efficiently: A shared storage solution allows re-allocation of disc space at a moment's notice. Easy Transition: A shared storage solution can be easily added and installed on to your existing network and expanded as you need more storage space. Prevent Bottlenecks: A shared storage solution means that you no longer have to rely on your servers to do all of the work. · Expand Easily Once the data is on a SAN, the data is in a permanent home- no need to worry about data migration ever again! Expanding your existing storage space is as close to plug and play as it gets. Increase Attainment: A shared storage solution frees up teachers and pupils to use their imagination; media rich classes can be accompanied by faster log on times Be the hero: A SAN means less downtime
- Another way to decrease the costs of running your network is to virtualise. Virtualising your servers migrates physical servers on to a VMware operating system. This allows you to consolidate your various servers on to a single hardware platform. Schools and colleges place particular demands on networks and so we've spent time understanding the load on servers to generate a robust design for the virtualised network that will work in schools. When you virtualise your network, VMware vSphere is our recommended solution to house your virtualised servers. There are four versions of VMware available from RM: vSphere Essentials vSphere Essentials Plus vSphere Standard vSphere Advanced The features of vSphere are: VMware ESXi 4: This is the operating system used on your hardware vCenter: Allows you to manage your virtualised servers through a central management console. Update Manager: This allows you to manage and schedule updates to the operating systems. vMotion: vMotion is a tool that allows you to move your virtualised servers between hardware without having any virtualised server downtime. Fault Tolerance: Fault Tolerance is a tool that allows virtual machines to be migrated seamlessly from one physical hardware to another without any system downtime. Depending on the version of VMware vSphere that is purchased will depend on which of the above features are available.

- The Terminal Server carries out all the processing and can be used as you would use a desktop computer. Thin clients are suited to low demand applications such as web browsing and Microsoft Word. It is not recommended to use high demand applications such as multimedia and digital video editing as this may deteriorate performance of the software or the network. It's important to manage the applications on the server carefully in order to maintain maximum performance. If you are considering using older computers and converting them to thin client devices, then there is a product available called iGel. iGel produce software called Universal Desktop Convertor that allows you to migrate your existing computer into a fully manageable IGEL Universal Desktop thin client-like device. It is capable of delivering Terminal Server desktop applications. Also included with iGel is free, thin client deployment and management software, with which you can quickly and securely manage and administer the converted computers. iGel is based on Linux and is installed on the hard drive of the computer you want to use as a thin client. The iGel Universal Desktop Converter is an ideal introduction to thin client technologies and minimises the costs of buying new client hardware and allows you to reuse your older computers. Of course, you don’t have to just older computers if you want to use thin clients on your Community Connect 3 or Community Connect 4 networks. A second option is to use thin client devices. These are simply a dumb-terminal which allows a mouse, keyboard, monitor, and network connection to be connected to your network and make use of a Terminal Server. From a Sustainability point of view, there are many advantages of thin clients and Terminal Servers: Thin clients are cheaper to buy than standard desktop PCs and laptops. Thin clients have a longer lifespan than PCs and notebooks as there is less inside them to go wrong. They typically last for five to eight years whilst PCs and laptops usually have to be replaced after between three and five years. This means the amount of time between your hardware refreshes is extended, so you spend less over a period of time. They consume less energy than PCs and laptops. They produce less heat than PCs and laptops, which reduces the need to use air conditioning to keep your classrooms cool. You consume fewer raw materials by extending your hardware lifespan through the use of thin clients, which means you reduce your energy consumption over a period of time. You have to carefully consider whether Thin Clients will suit your establishment. For example, the majority of thin clients will not have audio capability or the ability to use removable storage devices such as a USB drive. If you're planning to connect peripherals to your thin clients (for example; USB drives, projectors or interactive whiteboards), we advise you to check the capabilities of the devices to ensure they support this functionality.
