NVM Express Seminar (5 Modules) – With Optional Modules

-NVMe has been designed from the ground up to match the advantage of SSD with the speed and availability of PCIe. It is built on the proven and efficient PCIe interface by engineers and architects familiar with both storage and PCIe. Sign-up today for a public or on-site seminar!

KnowledgeTek is pleased to announce that our NVMe includes the definitive textbook concerning this interface. This material is provided at no cost to the attendees. This book is in addition to the usual KnowledgeTek training manual and our PCIe/NVMe reference manual.

The following modules expand the knowledge of NVMe in various directions depending on the needs of the audience. Times are listed for the duration of
each module. These modules may be added to the basic NVMe training, or presented standalone.

PCIe BASICS for NMVe – 2 hours
NVMe does not cover the transport, data transfer, or interrupts. Those services are provided by PCIe for the original NVMe or Fabrics for NVMe over Fabrics. This optional module provides necessary training to understand those three subjects.

PCI/PCIe Concepts
– Configuration Headers
– Addressing
Topology Discovery and Enumeration
PCI Transactions
Interrupts and Masks
– INTx

NVMe – MI – 1 hour
Originally management of the NVMe devices (controllers) was provided by in-band Admin commands. To provide out-of-band management, an NVMe-MI specification was developed. The first version provided basic read-only capabilities (referred to Basic Management below), the next version added control capability with two different out-of-band transports, and finally the out-of-band capabilities were provided for in-band management through two new Admin commands.
