10g packet capture 1U front

Ultimate 20G packet capture

20g packet capture 1U raid5            

Full duplex 2x10Gbps traffic sustained line rate packet capture is hard. Whats even harder is sustained 20Gbps packet capture at a reasonable price, but we have done it so you get the maximum value from your infrasturcture.

Our FMADIO 20G packet capture system is designed for simultaneous full duplex Rx and Tx line rate 64Byte 30Mpps 2x10Gbps traffic. The result is a cost effective 20Gbps packet capture system for the absolute best value on the market today.

16 TeraBytes of RAID

Large total capture capacity is critical for network and security forensics. Our 16TB(raw) RAID5 storage keeps your data safe and secure using the open source linux software RAID stack. This means no funky raid hardware problems and rock solid opensource code that's stood the test of time.

2 TeraBytes of cache

We use an ultra fast, high bandwidth 2TB solid state cache to guarantee 100% packet capture with 30Mpps at full 20G line rate. During capture this cache is constantly flushed on a best effort basis to RAID5 (or RAID0) magnetic disk array. Creating the ultimate blend of high performance 100% line rate packet capture, with massive storage capacity at reasonable prices.

Hardware Time Stamp

All fmadio20G devices use hardware timestamping for high precision nanosecond level timing. This enables monitoring at the highest resolution for even the most latency sensitive applications.

Full 20Gbit Line Rate

Line rate capture and processing to disk are absolutely critical features to have. Not only do we capture and store to cache at full 2x10Gbit line rate we also index in real time to calculate data CRC`s and ensure captured data retains its data integrity.

Hybrid SSD & HDD

Out system takes a hybrid approach to utilizing both SSD flash devices for their high bandwidth and HDD magnetic disks for their storage density. This creates the optimal blend of cost vs performance while maintaining your data on a RAID5 array, all in an tiny 1U profile.

Microburst Analyzer

FMADIO Packet capture is more like a packet database. You can view captures split by time (1sec/10sec/1minute/10min/1hour) or by size (1MB/10MB/100MB/1GB/100GB/1TB) or use our excellent microburst analyzer to view, inspect and finally extract only the packets you require.

Built in GPS

We support NTP, PTPv2 and external PPS signals. But in cases where there is no high quality time GrandMaster you can utilize the onboard GPS satellite receiver and achieve sub 100ns accurate world time calculated from up to 22 simultaneous satellites.
