SANTA CLARA, Calif. -- November 15, 2012

The NVM Express (NVMe) Work Group today announced it is releasing a new
version of the specification NVMe 1.1, bringing a new level of enterprise and
client functionality. NVMe is an optimized, high performance and scalable host
controller interface that unlocks the potential of PCIe® solid-state drives
(SSDs) now and in the future, and standardizes the PCIe SSD interface with the
NVMe 1.0 specification.

For enterprises, the NVMe 1.1 specification adds support for PCIe SSDs with
multiple PCIe ports to enable multi-host usage models such as Multi-Path I/O
and namespace sharing, enhanced reset capabilities, and a simplified
reservations mechanism compatible with SCSI reservations, increasing fault
tolerance. For both enterprise and client platforms, the NVMe 1.1
specification adds autonomous transitions during idle time to reduce platform
power consumption.

“As the storage market leader, EMC requires drives that meet the highest
standards for reliability, availability, serviceability and performance,” said
Bill DePatie, vice president of global hardware engineering at EMC and NVMe
Workgroup Member. “The latest NVMe 1.1 specification adds high-end,
enterprise-class drive capabilities to PCI Express SSDs. These features enable
broad interoperability for the next generation of PCIe flash devices, and
accelerate innovation in the systems and architectures that are built from
them. By standardizing many enterprise-class features, the NVMe specification
is enabling the industry to deliver higher performance PCIe SSDs without
compromising on expectations for drive functionality—which is especially
important as customers continue transforming their IT infrastructures.”

The NVMe Work Group consists of more than 80 companies from across the
industry with a goal of driving the adoption of SSDs using the PCIe interface.
This specification, and future versions, will enable the industry to have
secure, efficient and fast access to their data.

“The NVMe 1.1 specification is another milestone on the path to broad adoption
of SSDs using the PCI Express interface and toward unlocking the full
performance potential of SSDs,” said Sumit Puri, senior director of strategic
marketing, Flash Components Division, LSI Corporation and NVMe Workgroup

“As a developer of the world’s first NVMe enterprise flash controllers, IDT is
leading the charge in PCIe-based flash controller innovation,” said Kam
Eshghi, senior director of marketing, IDT Enterprise Computing Division and
NVMe Workgroup Member. “NVMe 1.1 provides high-end features such as support
for dual-port PCIe SSDs to get the most out of high performance enterprise

This new release demonstrates the rapid development and maturity of the NVMe
specification and the infrastructure surrounding, and supporting, PCIe SSD
devices. The NVM Express 1.1 specification is available for download at
