        Non-Stop is for the first tier (at least it was 2 years ago)...
        the other two tiers (mid-tier and backend) are Windows based

http://www.onwindows.com/article.asp?id=25

The first tier receives
quotation information from SuperMontage's Hewlett-Packard Non-Stop
Computing mainframe platform. The second tier processes and
maintains the data, while the third tier disseminates the information
to SuperMontage's subscribers.

[snip]

The second tier, running on Windows 2000 Server and SQL Server
implemented on two Dell 8450 four-processor servers, manages all
business logic using stored procedures. Each quotation, or message,
causes a SQL Server stored procedure to execute four or five database
calls to process the message and load it into the database. SQL
Server business logic reviews all the reference information associated
with the message, such as the state of quoting participants. It
prepares relevant information to be included with the eventual
transmission of the quotation data to subscribers. It analyses whether,
and where, the new quotation fits among the top five bid and ask
prices.

The third tier pulls data from the SQL Server database and multicasts
it to all SuperMontage subscribers. This layer is implemented on three
dual-processor Dell 2250 servers running Windows 2000 Server. Each
processor supports a single channel of output, and each server has a
backup machine for failover.

"Quite candidly, when we started the project, I had my doubts whether
Microsoft could deliver on enterprise-class applications," he
concludes. "But I think the results speak for themselves. Microsoft can
deliver."

Men with walkie-talkies                 I'm home again to you babe
Men with flashlights waving             You know it makes me wonder
Up upon the tower                       Sittin' in the quiet slipstream
The clock reads daylight savin'         Rollin' in the thunder
