DX2040 compression and security acceleration card delivers unprecedented compression and security performance to OEMs in the data
analytics, storage, and cloud security markets. The DX2040 provides 40 gigabits/sec of simultaneous compression, encryption, and hashing while supporting up to 40,000 operations/sec of RSA (2048 bit key size). The DX2040 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 40 gigabits/sec of device throughput.
Connecting to the host with an eight lane PCI Express 3.0 interface, the DX2040 offloads the host from CPU-intensive compression, encryption, and public key algorithms, providing the processing power of hundreds of enterprise class x86 CPU cores at much lower power and cost. The DX2040 Class of Service provides multiple command queues to prioritize traffic, enabling OEMs to avoid over provisioning and enforce service level agreements for performance critical applications. The DX2040 incorporates Single Root I/O Virtualization (SR-IOV) to support virtualized environments, integrating 128 virtual functions.
The DX2040 includes a user friendly Software Development Kit (SDK) which includes a wide range of features for enhanced performance, advanced management and monitoring, and high reliability and availability, and the SDK is API-compatible with Exar’s DX1700 and DX1800 families of compression and security acceleration cards. In addition, the DX2040 has been integrated with AltraHD, Exar’s hardware accelerated compression solution for Hadoop, as well as Exar’s hardware accelerated OpenSSL package.
The DX2040 is available in a compact low profile, half length form factor, enabling easy integration and deployment across a wide range of platforms.
Key Benefits
The DX2040 leading edge compression engine minimizes the data footprint while maximizing performance, delivering a multitude of benefits. Costly I/O bottlenecks for both storage and networking are removed or minimized, enabling maximum system throughput at minimum latency.
Storage and data analytics applications benefit from higher bandwidth disk I/O and higher storage capacity. Data encryption and hashing are alsosupported in addition to compression without suffering penalties in either performance or latency.
The DX2040 supports a wide range of encryption, authentication, and public key algorithms for networking security, providing all required support for IPsec and SSL/TLS/DTLS, including high performance public key processing, which enables the secure infrastructure needed to support the high transaction throughput required by cloud and web-based applications. Security features also include support for the elliptic curve cryptography (ECC) algorithms and Suite B.
Target Applications
The DX2040’s high performance, scalability, and low power addresses the requirements for a variety of enterprise applications, including data warehouses, Hadoop clusters, storage arrays, application delivery controllers, WAN optimization appliances, security gateways, and hardware security modules.
