Key Notes
* bxp API is available only through the firewall but for ease of diagram is posted differently above.
* USB1 is conceptual for off-site data removal procedures. Ports restricted and bitlocker required on any connection.
* Db2, will become an active server, rather than a passive backup server.
* The hard drives in the Db servers are being changed from 7200 rpm drives to Solid State Drives, which will see throughput increase over 10 fold.
* Previously if we’d used Db1, the tables would lock and the tills still would have been unusable. Instead, we’re able to allow W3 to chat to Db2, which is being kept up to date in real time. This means the tills aren’t affected and yet we can do very memory intensive operations.
* This change addresses KeyStats generation speed issues, as they will be created on W3.
