IT – Capacity increase in SAXESS for OMX Nordic Exchanges and Oslo Exchange (54/07)

We are continuously adjusting the data communication capacity to match with the data communication demands. We are experiencing an increase in the number of transactions within the activities on the NOREX platform (SAXESS). We have therefore decided to increase the capacity in steps. Our aim is to achieve this in the most efficient way.

We have split up our SAXESS system in three different partitions, one for equities, one for warrants, and the third for fixed income. The aggregated data output rate from the three partitions is currently 14400 zB (compressed bytes per second). The decision to increase the partition one (equities) to 15 000 zB from 5th of November. In second step to increase partition 2 to 4 000zB and 6 000 zB from 3rd of December. 

The capacity increase will be implemented in production from 5th November and 3rd December 2007.

Member actions to prepare for the capacity increase:

Members will need to take the following actions:
•	Verify that your own trading application(s) can cope with the increased capacity (a total of 20 000 zB in step 1 and 25 000 in step 2). Your trading application is certified for this bandwidth, but we strongly recommend that you test your setups before the increases.

The test system (SAXTST3) is configured with regular load tests of 20 000zB. For detailed information please check separate information about the test systems on our member web pages.
