I?m not too sure this is the correct area to post this type of question as it is network related, but I?m hoping you guys can help anyway.
One of our clients wants to save on network costs and move from a fixed point to point (2Mb) link from their network to ours to a public internet routed VPN connection.
I?m not a network guy but this seems to me to be a potential for increased latency, and reduced response times due to the additional routing that is likely to over the public internet plus the higher contention ratio that is likely to be on the line over a direct site to site.
Having said that the likely hood is that we would allocate 5Mb for the VPN tunnel at our end.
The question I have is two fold, one am I worrying unnecessarily, they would after all only be using standard iAccess for Windows sessions for 5250 emulation. There is spooled data produced and sent to remote writers (physical printers on their network).
There is generally an average of 50 ? 60 concurrent users and their workload is predominantly interactive, although a few functions do submit batch jobs.
The second question is, does IBM publish a minimum specification of line or network that should be used for iSeries access workloads? If so can anyone point me in the right direction please?
The problem is I don?t have any information to go back to the client to advise either way as to the legitimacy of their plan.
