Kalray Launches Krypto128 Accelerator Card

By Nick Flaherty www.flaherty.co.uk


French chip designer Kalray has moved into the data centre market with a programmable accelerator for high speed encryption.

The Krypto128 card is based on the second generation of MPPA processor called Bostan which combines high computing performance with real-time processing and low power consumption. The card can replace up to eight Xeon processors to cut costs.

Kalray started back in 2012 by integrating 1024 digital signal processing cores on a single chip to provide the same performance as FPGAs.  The Bostan chip integrates up to 288 C/C++ programmable CPU cores and 128 crypto co-processors with a fully deterministic and real-time architecture. 

The company is aiming at two main markets with its Krypto128 card. The first market concerns storage computation pipelines, which include algorithms such as compression, encryption, erasure coding and integrity checks. This computation pipeline can be found at several places in the data center, either in the main server, if SSDs are attached to it, or in the storage proxy I/O server - or even in the all-flash array cabinet storage server. In any of these cases, this suite of computation on the data before writing or after reading to or from the SSDs requires numerous cycles of the main processor and can be offloaded easily on the Krypto128 PCIe card.

Kalray has customer use cases in which a Krypto128 card can offload and replace up to 8 Intel Xeon E5 2630v3 @2.4Ghz when implementing a Lz4 compression, an AES128 encryption, an erasure coding (8 to 10) and a CRC 32 bits on 4K block of data, resulting in a significant 3 x system cost reduction.

A key advantage is that the Bostan chip is fully programmable in C and C++ so that customers can easily use a wide range of algorithms such as AES256/126, Sha256/128 and CRC32. Depending on which algorithm is implemented, performance of up to 60Gbits of bandwidth can be achieved.

"Kalray is fully committed to offering solutions to our customers that help them to quickly introduce SSD technology, with all its latency benefits, into their data center," said Eric Baissus, CEO of Kalray. "And, more importantly, this gives them the possibility to scale up the technology in a cost effective manner."

The second market targeted by the Krypto128 concerns IPsec and OpenSSL transparent acceleration into VPN routers or secure gateways. These are commonly found in the network between, for instance, a private enterprise data center located at the customer premises and a remote public cloud where the customer may rent some hardware services. Performance in these use cases is phenomenal and can go up to 120Gbits of bandwidth.

Kalray provides all the basic software modules required to implement those functions. Communication between the main server and the Krypto128 card is mainly based on the standard socket API with an AF_ALG extension interfacing with MPPA specialized engines, which in turn enables transparent acceleration for either the storage computation pipeline or OpenSSL and IPsec stack. Kalray also offers all software acceleration engines implemented on the MPPA high-speed I/O processor, from crypto, Sha, CRC and compression, to erasure coding. In addition, the customer is able to customize and add new features.

The Krypto128 card is a single width, full height, half-length PCIe programmable card with 16 lanes of  Gen3 PCIe and typically consumes 25W.
