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
 - Compression ratios comparable to Level 9 gzip
 - 40,000 operations/second of RSA with 2048 bit keys
 - PCI Express 3.0 host interface with 8 lanes
 - Low profile, half-length PCI Express form factor
 - Support for gzip, zlib, Deflate, and eLZS compression algorithms
 - Support for a wide range of encryption, authentication, and public key algorithms, including support for elliptic curve cryptography (ECC) and Suite B
 - Class of Service provides multiple queues to prioritize traffic
 - Single Root I/O Virtualization (SR-IOV) integrates 128 virtual functions
 - DX2040 Software Development Kit (SDK) is compatible with Exar' DX1800 and DX1700 families of compression and security and acceleration cards
