Growth of NVMe
•
“Enterprise SSD market is expected to reach $4 billion in
revenues by 2016, nearly six times that of 2011, while unit
shipments are expected to increase by ten times during
that period, to approximately 4 million units.”
- Forbes.com July 2014
•
NVMe is the next gen interface for both client and
enterprise systems.
NVMe products announcements are happening
There is a strong need to demonstrate the interoperability
of NVMe products.
The NVMe plugfest at UNH-IOL is a key component in
accomplishing this.

NVMe Test Program Overview
 Since 2012 NVMe Promoters Group
collaborating with UNH-IOL to manage the
Integrators List based Test Program for
NVMe.
9
NVMe Integrators List
NVMe Integrators List
hosted by UNH-IOL as
of Sept 30, 2014:
https://www.iol.unh.edu/services/testing/NVMe/integratorslist.php
10
NVMe Integrators List
• NVMe Integrators List is the industry
resource for listing products proven to
interoperable and conformance according to
industry accepted test practices.
• Listed products demonstrate commitment to
interoperability and open standards
conformance.
• OEMs viewing Integrators List qualification
as necessary for components.
11
NVMe Test Program Goals
 Prove the robustness and
interoperability of NVMe through
continually improving interop
and conformance testing.
 Help implementers ensure the
conformance and interoperability
of their products
 Provide recognition for products
meeting the necessary
qualifications backed by test
reports.
12
How do we populate the Integrators List?
 New Interop and Conformance
Testing Requirements approved by
NVMe Promoters group
 New Testing requirements launched
at plugfests.
 Testing for Integrators List
performed throughout the year at
UNH-IOL.

NVMe Plugfest Components
 NVMe Plugfest #3 November 10-13, 2014
will test according to version 1.1b of the
NVMe Test Program.
 First opportunity to test devices to the
new requirements and have them listed
on IL.
 After the Plugfest, UNH-IOL members
can request 1.1b Integrators List testing
throughout the year.
15
Test Plans
2 Test plans will be
executed at the plugfest.
1. UNH-IOL NVMe

16
Common Test Terms
Mandatory
• DUT must pass test in order to qualify for IL.
Optional
• If DUT supports an optional NVMe feature, it
must pass test inorder to qualify for IL. If
option is not supported, the test is not
performed and does not affect IL qualification.
FYI
• Test does not affect IL qualification, but may
become mandatory in the future.
17
Passing Requirements Overview
Conformance Tests
• DUT must pass all mandatory conformance
tests supported by test tools
• If feature is supported, DUT must also pass
optional tests supported by test tools
18
Passing Requirements Overview
Interop Tests
Plugfest #3 (Today)
DUT must pass mandatory tests with 4/5 systems.
FYI tests do not affect IL qualification, are only
performed with 1 system
Plugfest #4 (2015)
DUT must pass mandatory tests with 5/6 systems.
FYI tests will become mandatory, are only performed
with 1 system
19

Why 2 Conformance Tools?
•
•
•
Community needs a tool with a relatively low
cost barrier, to be able to determine
conformance. The PC Edition meets that
need.
Community also needs a tool with deep
debug and analysis capability. TeledyneLeCroy edition meets that need.
Tradeoff: Cost vs. Debug Capability + Trace
Analysis

43
Listing Products
Listed Information Includes:
 Product, includes Manufacturer, Model Name and Family
Name (i.e. different capacities of one SSD are in a single
family)
 Product type (accepted products types are: NVMe SSD, SSD
Controller, or SSD Controller IP, server, server board,
motherboard, add-in card, RAID Controller, or IP device).
 Operating System and Driver (Host Only)
 Firmware revision (Device Only)
 Interop Program Revision (i.e. 1.0, 1.1, 1.1b etc...)

44
Listing Similar Products
 Products with differences that do not affect
NVMe operation (form factor, storage
capacity) can be listed under a single
product listing, “listed by similarity”.
 The products listed by similarity must have
the same Firmware revision and Model
Name, and the listing company confirms
that the products are materially similar with
no substantive changes to the NVMe
interface.

Review
•
•
•
•
•
NVMe Test Program focused on Integrators List to
showcase interoperable and conformant products.
Test tools and plans available from UNH-IOL.
Plugfest will allow the first opportunity to list
products on the NVMe Integrators list v1.1b.
Plugfest will walk SSDs through multiple
conformance and interop stations.
Testing can continue after the Plugfest for those
unable to attend.

Q&A
Contact: [email protected]
52
Q&A
• When will the 1.1b IOL-INTERACT
Linux and Lecroy tools be available for
download?
• As far as test support, the currently released
tools support all the necessary tests. Future
releases prior to the plugfest will contain bug
fixes and update LeCroy software support.
53
Q&A
• FYI boot from NVMe will require an OS
to be installed. What if the NVMe
device is too small for an OS to be
installed?
• Then the test cannot be performed. This is why
we have this as an FYI test today, so that you
can properly prepare for the next plugfest and
have a device large enough for an OS then.
54
Q&A
• How does the CEM adapter support
hot-plug testing as the server
motherboard PCIe slots also should
support the hot plug
• We will not be performing hotplug on CEM
card systems or devices. ·
55
Q&A
• What is the difference between github
version and iol-interact SW other than a
gui interface?
• IOL INTERACT supports test groups 3, 4, and
5, which tNVMe does not directly support.
56
Q&A
• Slide mentions IOL-Interact 1.1, but not
1.1b release
• In this case the 1.1 refers to the software
version. The 1.1 software version supports most
of the tests required for the NVMe IL version
1.1b (see table on slide 31 ). It’s just an
unfortunate coincidence that the numbers are
close.
57
Q&A
• Is PCIe phy conformance available for
non-CEM form factors
• Yes
• Is UEFI testing available on any
motherboard that can be done locally?
other platforms that support UEFI
• Yes, the test can be performed on any platform
that supports UEFI, but UNH-IOL will only
supply 1 platform at the plugfest.
58
Q&A
• Is there a deadline for registration?
• October 17, 2014
• Do you use Solaris host for interop test?
• Currently we don’t have a Solaris host for this
interop event. However, using a Solaris host as
one of the hosts for interop testing would still
help qualify an SSD for the IL.
59
Q&A
• We are interested in bringing a server
instead of a drive. Would you require 2
models the same as you want for
drives?
• Bringing a single server is fine. We only need
two samples of SSDs.
