1 The user interface is designed for normal business usage, large rulesets, high number of users or interface assignments may be less practical.

All measurements are based upon TCP traffic unless stated otherwise. Total Firewall Throughput is calculated based on system utilisation and port-to-port performance test in full duplex. Maximum PPS is measured using 100 byte packets. IPS performance is measured using ET Open and standard 1500 byte package size. SSL VPN is measured using AES256GCM16+SHA512. Concurrent sessions are based upon memory available, where one state consumes 1KB of memory and 1GB of memory is reserved for system tasks. Latency is measured as an average over 60 seconds.

Supported SFP(+) Modules

When using SFP+Modules, do not mix 2.5/5Gbps and 10Gbps link-speed as the hardware does not support mixing these due to different frequencies.

While most standard LC-LC OM3 SFP+ modules and SFP+ Direct Attached Cables are likely to function we advise to select one of of the known compliant modules from the following list:
