Corvil Pushes Latency Management Towards Big Data

With an effective storage capacity of 60 terabytes, Corvil’s new CNE-7300 latency measurement appliance can retain tick data over an extended period, potentially making it useful as a data archive for ‘big data’ applications beyond latency management.

According to Donal O’Sullivan, head of product management at Corvil, the CNE-7300 will likely be able to store 50 days of option tick data from OPRA, which is the highest message rate and volume consolidated feed around.  O’Sullivan bases that estimate – and he notes it is indeed an estimate – on a daily OPRA peak of around five billion messages per day, and 250 bytes per message (including derived data stored with each message received).

Applications – such as back testing and transaction cost analysis – have access to the data via an XML SOAP interface, says O’Sullivan.  That interface allows search and filtering of datasets, as well as optional indexing for faster retrieval.

The CNE-7300 also leverages Intel’s latest ‘Sandy Bridge’ chips for performance, enabling it to process two million messages per second.
