The DX2040-SX4 compression and security acceleration card delivers unprecedented compression and security performance to OEMs in the data analytics, storage, and cloud security markets. The DX2040-SX4 provides 30 gigabits/sec of simultaneous compression, encryption, and hashing while supporting up to 40,000 operations/sec of RSA (2048 bit key size). The DX2040-SX4 value proposition includes best in class compression ratios at maximum throughput, delivering compression ratios that are comparable with gzip level 9 while sustaining the full 30 gigabits/ sec of device throughput.

  • 30 gigabits/second of processing throughput with simultaneous compression, encryption and hashing
