1. This will require a high-quality network connection between remote offices and server farms. Ideally, this should be a dedicated channel with low delay, but you can also use the technology of virtual private network (VPN) and keep in touch over the existing Internet connection. Choosing the type of communication depends on the type of access you want for your business, and the tools that you can allocate for this purpose. If you don’t need to frequently transfer large amounts of information between the server center and office, you may not need a channel with broadband – just use the T1 lines or similar.
However, if you often transfer large amounts of data, you have to think about establishing a partial or complete DS3 connection.
2. You have to spend money on switching (KVM, keyboard, video card, and mouse) over IP for all computer servers based on PC. For Unix systems require Internet access to the server console. Most likely, you will not use any of these ways: It is better to use RDP (Remote Desktop Protocol – RDP) to remotely manage Windows and SSH for remote administration of Unix or Linux because these systems are much faster than the KVM-based IP or console switches.
Sometimes, however, you may require access to a keyboard/monitor or console port server. For example, you may need to access the BIOS setup screen, you will need to enter single user mode in Unix, etc. Many manufacturers offer Spurious card remote control, but it seems much easier to manage, unified solution KVM over IP.
3. It is strongly recommended to make use of control over an IP network extension, enabling remote reboot completely “hung” servers. As we know, most service providers offer free server colocation that remotely reboots servers, but experience shows that it takes too much time. When the system is denied, the time – the money, and seem like an eternity in the 15 minutes when you sit helplessly in office, waiting for the technician remote data center to reboot your server. With access to the extension with remote control, you can make yourself rebooting many times faster.
4. Provide your technical support hardware firewall and high-speed Internet access, to connect to the data center and access a remote server. This will give your staff a reliable and effective tool for managing all remote servers. This approach is very important for the effective support of on-demand, and it is also useful.
However, if you follow the advice listed above, the benefits of server colocation in a specialized center will outweigh the disadvantages caused by this choice.
