Introduction
Rev 1.8 13 Mellanox Technologies
RDMA and RDMA
over Converged
Ethernet (RoCE)
Mellanox Innova IPsec adapter supports RoCE specifications delivering low-
latency and high- performance over Ethernet networks. Leveraging data center
bridging (DCB) capabilities as well as Mellanox Innova IPsec adapter advanced
congestion control hardware mechanisms, RoCE provides efficient low-latency
RDMA services over Layer 2 and Layer 3 networks.

communication provides high efficiency RDMA access by
eliminating unnecessary internal data copies between components on the PCIe
bus (for example, from GPU to CPU), and therefore significantly reduces
application run time. Mellanox Innova IPsec adapter advanced acceleration
technology enables higher cluster efficiency and scalability to tens of thousands
of nodes.
CPU offload
Adapter functionality enabling reduced CPU overhead allowing more available
CPU for computation tasks.
Quality of Service
(QoS)
Support for port-based Quality of Service enabling various application
requirements for latency and SLA
Storage
Acceleration
A consolidated compute and storage network achieves significant cost-
performance advantages over multi-fabric networks. Standard block and
file access protocols can leverage RDMA for high-performance storage access.
Distributed RAID
Mellanox Innova IPsec adapter delivers advanced Erasure Coding offloading
capability, enabling distributed Redundant Array of Inexpensive Disks (RAID), a
data storage technology that combines multiple disk drive components into a
logical unit for the purposes of data redundancy and performance improvement.
Mellanox Innova IPsec adapter’s Reed-Solomon capability introduces redundant
block calculations, which, together with RDMA, achieves high performance and
reliable storage access.
