Versions¶
The n2disk software comes in four versions: n2disk1g, n2disk5g, n2disk (10g and above), depending on the ingress traffic rate that need to be processed (note: there is no constraint on the link speed or number of links).
n2disk1g (1 Gbit/s)¶
This is the entry-level version, enough for rates up to 1 Gigabit.
n2disk5g (5 Gbit/s)¶
This is the standard version, with two threads: one for packet capture and one for disk writing. This version can handle rates up to 5 Gigabit.
n2disk (10/40/100 Gbit/s)¶
This version includes support for ZC and multithreaded traffic processing, with an internal architecture able to load-balance pcap processing and indexing on multiple threads. This version can handle 10 Gigabit and above.
