Credit Suisse has implemented flash memory technology from supplier Fusion-io as it attempts to increase trade volumes on its existing infrastructure.

The ioMemory technology has been added to Credit Suisse's Advanced Execution Services (AES) trading platform to improve data access performance and maximise the effectiveness of its architecture.  

"As our trading businesses continue to grow in size and complexity, driving greater efficiency and performance in the supporting IT infrastructure becomes ever more important,” said Marinela Tudoran, global head of alternative execution platform technologies at Credit Suisse.

“Combining Fusion’s solid-state memory solution has allowed us to increase performance while achieving higher levels of reliability in our IT infrastructure," said Tudoran.

Credit Suisse engages heavily in algorithmic trading, which uses complex formulae to determine what trades to execute and when to execute them. The number of transactions that a financial organisation can perform depends heavily on the average latency at which these trades can be logged, or saved from volatile DRAM memory into permanent storage.

Improving the overall efficiency of the system, including CPU utilisation, creates a more agile, faster computing system that can transact greater trade volumes, according to the bank.

Credit Suisse has adopted virtualisation in its data centres to slash energy use. Around 25 percent of its servers are now virtualised.
