Can a 10 Gbps connection support data analysis between the DRAGEN server and storage server?

Can a 10 Gbps connection support data analysis between the DRAGEN server and storage server? Will the connection be stable?

Yes, the DRAGEN server is designed to be used with a storage system and 10 Gbps is the recommended connection speed. As long as the connection between the DRAGEN server and storage unit is stable, users should not experience any issues with the analysis. Each lab's networking environment is unique. Illumina recommends that users consult with their IT department to confirm that the networking setup meets the recommended specifications for DRAGEN. DRAGEN will run at speed if there is a sustained IO of 300Mbytes/sec with the storage system. If data IO is slow, DRAGEN will run slower. If there is very high latency, DRAGEN runs watchdog timers that will trigger an error rather than wait for a long time.

Note: The default storage location for intermediate analysis files is the --output-directory specified. To avoid I/O latency when using a networked output location, use the --intermediate-results-dir argument to set a local directory (eg, /staging/tmp) as the scratch space for DRAGEN.
