//NOTE> SERVER COSTS ARE LARGELY UNKNOWN// //NOTE> SERVER LOADS ARE TOTAL UNKNOWN// //NOTE> ALL SERVERS WILL BE ON FIBRE LAN AND COMPUTERS OF THE DEVELOPEMENT TEAM WILL BE ON GB LAN//


 * Master Server Plan**

Two backup sites in different geographical locations for disaster management connected via dark-fibre network for real-time mirroring.

On-site backups

Game server cloud/cluster

Database Server


 * Data Backup Server (1 at each site)**

IBM System Storage DS5000 Series 268.8 TB (fibre channel drives)

To be fibre linked to main site (requires infrastructure to already exist at site)


 * The Game Servers Themselves**

~100 * IBM blades each with 2 * dual-core 3.3Ghz CPUs


 * Database Server**

IBM X3850 M2 server, 128 GB RAM, 2 * 2.6 GHz 6-Core Xeons

Texas Memory Systems RamSan-6200 (storage) //While seeming overkill, we chose this larger, slower (65ms read/50ms write) because it would mean it would only need be replaced if it broke down or our online population exceeded that of a small country.//


 * Network Backbone**

Cisco Catalyst 3560G-48PS Switch (Game/Database servers)

Cisco Catalyst 4500 Series Switch (Developer Network)

Cisco CRS-1 Carrier Routing System (responsible for all main-site routing)

Hardware will need to be reliable and powerful as with an estimated 500,000 unique subscribers in the first year, we can expect approximately 100,000+ to be online concurrently.
