PowerStore is joined to four application servers in a cluster. We're running an application that we use to monitor our activity in the financial markets. We collect all the data from the market—books, trades, orders—that we send to the market. In terms of volume, we are collecting about 100 million rows a day for the books, 10 million a day for the orders, and about 500 rows for public trades.
It is a mission-critical application because of compliance and the regulators. We have to maintain this kind of monitoring because it's a direct link to our activity in the regulated market.
