Tahoe-LAFS nodes that run a webserver have a page dedicated to provisioning

decisions: this tool may help you evaluate different expansion factors and

view the disk consumption of each. It is also acquiring some sections with

availability/reliability numbers, as well as preliminary cost analysis data.

This tool will continue to evolve as our analysis improves.

This page provides a basic tool to predict the likely storage and bandwidth
|

requirements of a large Tahoe grid. It provides forms to input things like
|

total number of users, number of files per user, average file size, number
|

of servers, expansion ratio, hard drive failure rate, etc. It then provides
|
||||
numbers like how many disks per server will be needed, how many read
|

operations per second should be expected, and the likely MTBF for files in

the grid. This information is very preliminary, and the model upon which it

is based still needs a lot of work.
