Key storage features include Live Migration, Computational
Storage, and a new Host Directed Data Placement Technology
NVM Express, Inc. today announced the release of three new
specifications and eight updated specifications. This update to
NVMe technology builds on the strengths of previous NVMe
specifications, introducing significant new features for modern
computing environments while also streamlining development and time
to market.
“Beginning as a single PCIe® SSD specification, NVMe technology
has grown into nearly a dozen specifications, including multiple
command sets, that provide pivotal support for NVMe technology
across all major transports and standardize many aspects of
storage,” said Peter Onufryk, NVM Express Technical Workgroup
Chair. “NVMe technology adoption continues to grow and has
succeeded in unifying client, cloud, AI and enterprise storage
around a common architecture. The future of NVMe technology is
bright and we have 75 new authorized technical proposals
underway.”
NVM Express Specifications Target Streamlined
Development
The latest NVMe specifications consist of multiple documents
targeted at allowing faster and simpler development of NVMe
architecture. The three new specifications are the NVMe Boot
specification, the Subsystem Local Memory command set and the
Computational Programs command set. The updated specifications are
the NVMe 2.1 Base specification, Command Set specifications (NVM
Command Set, ZNS Command Set, Key Value Command Set), Transport
specifications (PCIe Transport, Fibre Channel Transport, RDMA
Transport and TCP Transport) and the NVMe Management Interface
specification.
Key New NVMe Capabilities
- Enabling live migration of PCIe NVMe controllers between NVM
subsystems.
- New host-directed data placement for SSDs that simplifies
ecosystem integration and is backwards compatible with previous
NVMe specifications.
- Support for offloading some host processing to NVMe storage
devices.
- A network boot mechanism for NVMe over Fabrics (NVMe-oF™).
- Support for NVMe over Fabrics zoning.
- Ability to provide host management of encryption keys and
highly granular encryption with Key Per I/O.
- Security enhancements such as support for TLS 1.3, a
centralized authentication verification entity for DH-HMAC-CHAP,
and post sanitization media verification.
- Management enhancements including support for high availability
out-of-band management, management over I3C, out-of-band management
asynchronous events and dynamic creation of exported NVM subsystems
from underlying NVM subsystem physical resources.
The NVM Express specifications and the new feature
specifications are available for download on the NVM Express
website.
