We are a retail company dealing with textile , retail business. We have about 4 branches within the span of around 250 to 300 kms from our main office. In a branch we have about 60-70 computers with thin clients operating with the help of IBM BLADE server. Total, we have about 250-270 computers accessing the server.
The server is about 5 years old and in these 5 years everything was good except a few server and network issues because of which we had to go for manual billing and other processes and also it causes severe problems though the n/w and server errors occur for few minutes.
Our main usage of server is at point of sale , admin and accounts department.
Now we have an option to go for offline application which we could use at the time of main server faults and we have to merge the data from the offline app to main server DB everyday night.
Is it the good decision or can we go for a sub-server which could be used during n/w or server connection failure? Will the sub server concept be cost-effective and what would be the performance of it?
Please help us with your valuable solutions.
