I have the following question:
We want to replace our current network.
A Windows SBS 2011 Server and a Windows 2008 Server (Premium Add On).
It works for us the last years but we had a (very unexpected) grow in the company, so we get more then 100 extra users next year. SBS 2011 is not an option anymore also for the availability of our network, we get also extra office(s) in other places next year.
We have a quote for a new server:
- Xeon Processor with 6 cores
- 128 GB RAM
- 2 * 146 GB SAS Disk (15k, 6Gbps)
- 6 * 600 GB SAS Disk (10k, 6Gbps)
- Windows 2012 R2 Standard Edition with Software Assurance (two licenses)
- Windows 2012 User cals with Software Assurance
- Exchange 2013 Standard with Software Assurance
- Exchange Standard cals with Software Assurance
The price of the server is not a problem, but I have the following question. What do we need (and to do) to get a availibility option for us. I understand we have to buy an extra server and we can place it in another office. At this moment there is no VPN between the 2 offices.
Do you have a recommendation for our situation. Do we need a cluster or is it not necessarily? When we get a high availibility between 2 servers do we need to buy the user cals twice?
I hope someone can give us a good advice. I know some thing are 'beginner' questions, but I am 'official' a programmer. I learnt a lot in the last years about the systems.
Our management want to keep al the Infrastructure 'in house' and they want to spend some money on it. We can hire an expert, but maybe someone here give us a good summary of things we can do.
