This site might indicate that the 2006 contract, which has a higher dollar amount, was for the initial setup, which would include the hardware. It does mention "equipment." The following years' dollar amounts are lower. Could this be for cloud archiving of the data that was being backed up on site?
No, they don’t do that. The contract was for the IRS Office of Chief Counsel, so it didn’t even apply to the department Lois Lerner worked in.
The equipment would have been a drive array from Rorke, and it would have been installed at the IRS, not at Sonasoft, which does not provide servers at any Sonasoft facility.
A lot of people have been jumping to incorrect conclusions about this entire thing.
