PLDA Announces vDMA™, a Highly Efficient Many-Channel DMA Engine Engineered for Virtualized Systems in Data Centers, to Be Demonstrated at Flash Memory Summit 2017

PLDA’s vDMA allows thousands of independent and concurrent DMA channels to be distributed among a number of Virtual Machines without sacrificing performance or resource utilization

SAN JOSE, Calif.--()--PLDA, the industry leader in PCI Express® interface IP solutions, today announced their vDMA™ IP Core, a highly efficient many-channel DMA engine specifically engineered for SoCs that power tomorrow’s virtualized data centers. PLDA has created a demonstration of this new technology for exhibition at Flash Memory Summit 2017, to be held August 7-10, 2017 in Santa Clara, CA.

PLDA’s vDMA IP Core is based on a novel architecture that allows thousands of independent and concurrent DMA channels to be distributed among a number of Virtual Machines (VMs) without sacrificing throughput, latency, or resource utilization. Additionally, it incorporates the data protection and security features required by Enterprise storage and Networking applications.

The exponential traffic growth in Data Centers and the convergence of compute, storage, and network fabric within virtualized systems requires the development of SoCs that implement DMA engines that can move data efficiently between a large number of Virtual Machines. The traditional DMA architecture is limited, however, as it replicates resources for each DMA channel, leading to a high gate count, and typically does not implement the data security and VM isolation features required in today’s Data Center environments.

The PLDA vDMA IP Core solves these issues by providing the scalability required to support thousands of DMA channels and hundreds of VMs, without compromising on performance or resource utilization. This provides significant benefits for SoCs targeted at virtualized data center applications, such as multi-core and many-core network and flow processors, Smart NICs, NVMe and other storage controllers.

The main features of PLDA’s vDMA IP Core include:

  • Up to 2048 dynamically reconfigurable DMA channels
  • Up to 512 Virtual machines
  • Up to 128 outstanding read and write requests
  • Data path and Context memory protected with CRC and Parity bits
  • VM Isolation enforced with sideband signaling for identification and access control

According to Arnaud Schleich, CEO of PLDA, “PLDA’s vDMA IP core will enable our data center SoC designers to build devices that take advantage of virtualization more efficiently. This new DMA architecture will empower data centers to move even more data, with better performance and improved Quality of Services, for the benefit of Cloud users everywhere”.
