Benchmarking Performance: Benefits of PCIe NVMe SSDs for Client WorkloadsSamsung Business USA
The transition from Serial ATA (SATA ) to Peripheral Component Interconnect Express (PCIe) interface and Non-Volatile Memory Express (NVMe) protocol is taking client storage to a new level. This white paper discusses the benefits that PCIe NVMe SSDs, such as Samsung’s 950 PRO, bring to client PC users. Client PC workloads are not always well understood in the industry, since common benchmarking utilities tend to focus on measuring maximum performance rather than performance under typical PC usage. This white paper looks at actual IO traces of PC workloads to better understand how client SSDs should be benchmarked, and also tests the 950 PRO against other Samsung SSDs to show how PCIe and NVMe improve IO performance in tests that represent real-world IO activity.

Consolidation on Flash- Hardware for Nothing, Get Your Flash for Free (I want...Western Digital
By now, Tier 1 apps deployed on flash is ubiquitous. However, Tier 2 apps often remain relegated to spinning media. This presentation explains the economics of consolidating on flash. Owing to the SQL Server core licensing model, licensing a 2-socket commodity server can cost up to $500,000 or more! Consolidating instances on flash can—and does—save hundreds of thousands to millions of dollars. This presentation provides real-life case studies showing such real-life savings.
Today Micron announced the production of 8GB DDR4 NVDIMM, the company’s first commercially available solution in the persistent memory category. Persistent memory delivers a unique balance of latency, bandwidth, capacity and cost, delivering ultra-fast DRAM-like access to critical data and allowing system designers to better manage overall costs. With persistent memory, system architects are no longer forced to sacrifice latency and bandwidth when accessing critical data that must be preserved.

Reliable Hydra SSD Architecture for General Purpose ControllersIJMER
The Solid State Disks (SSDs) had almost replaced the traditional Hard Disk Drives (HDDs) in modern computing systems. SSDs possess advanced features such as low power consumption, faster random access and greater shock resistance. In general, NAND Flash memories are used for bulk storage applications. This project focus on an advanced SSD architecture, called Reliable Hydra to enhance the SSD performance. Hydra SSDs overcomes the discrepancy between slow flash memory bus and fast host interfaces like SATA, SCSI, USB etc. It uses multiple high level memory controllers to execute flash memory operation without the intervention of FTL (Flash Translation Layer). It accelerates the processing of host write requests by aggressive write buffering. Memories are subjected to bit flipping errors, so this project also considers the incorporation of matrix code for increasing the reliability and hence yield of the system. The highly sophisticated controllers for real time systems in the industrial, robotics, medical and scientific applications require high performance and reliable memories. The aim of this project is to design Reliable Hydra SSD architecture for controller applications to enhance the performance. The design architecture is to be coded in VHDL using Xilinx ISE tools.

Time and Low Power Operation Using Embedded Dram to Gain Cell Data RetentionIJMTST Journal
Logic compatible gain cell (GC)-embedded DRAM (eDRAM) arrays are considered an alternative to SRAM because of their small size, non rationed operation, low static leakage, and two port functionality. But traditional GC-eDRAM implementations require boosted control signals in order to write full voltage levels to the cell to reduce the refresh rate and shorten access times. The boosted levels require an extra power supply or on-chip charge pumps, as well as nontrivial level shifting and toleration of high voltage levels. In this paper, we present a novel, logic compatible, 3T GC-eDRAM bit cell that operates with a single-supply voltage and provides superior write capability to the conventional GC structures. The proposed circuit is demonstrated in 0.25μm CMOS process targeted at low power, energy efficient application.
A NEW MULTI-TIERED SOLID STATE DISK USING SLC/MLC COMBINED FLASH MEMORYijcseit
Storing digital information, ensuring the accuracy, steady and uninterrupted access to the data are
considered as fundamental challenges in enterprise-class organizations and companies. In recent years,
new types of storage systems such as solid state disks (SSD) have been introduced. Unlike hard disks that
have mechanical structure, SSDs are based on flash memory and thus have electronic structure. Generally
a SSD consists of a number of flash memory chips, some buffers of the volatile memory type, and an
embedded microprocessor, which have been interconnected by a port. This microprocessor run a small file
system which called flash translation layer (FTL). This software controls and schedules buffers, data
transfers and all flash memory tasks. SSDs have some advantages over hard disks such as high speed, low
energy consumption, lower heat and noise, resistance against damage, and smaller size. Besides, some
disadvantages such as limited endurance and high price are still challenging. In this study, the effort is to
combine two common technologies - SLC and MLC chips - used in the manufacture of SSDs in a single
SSD to decrease the side effects of current SSDs. The idea of using multi-layer SSD is regarded as an
efficient solution in this field.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. Enterprise applications have
become much more versatile
within the past decade, due to
the rise of Internet-connected
devices such as smartphones
and tablets. As the amount of
data that are generated every
day is growing and devices are
shifting away from high-capacity
local storage to cloud storage,
the requirements for enterprise
storage are changing and cost
considerations are becoming
more critical.
Today, there are numerous
classes of enterprise solid
state drives (SSDs) for different
applications, each with unique
performance and endurance
characteristics. One of the most
critical differentiators is the
underlying NAND technology,
which has been developing
rapidly in the past decade with
new innovations such as Multi-
Level Cell (MLC) and Vertical
NAND (V-NAND) technologies.
Choosing the right SSD for the
application is not necessarily an
easy task given the complexity
of the differences between
various NAND technologies.
This whitepaper explains the
fundamental characteristics of
two-bit-per-cell (MLC) and three-
bit-per-cell (3-bit MLC or TLC)
NAND technologies, as well as
the inherent scaling limitations of
planar NAND and how vertical
NAND (V-NAND) technology
solves these issues with our
innovative vertical structure.
Understanding the basics
of NAND is the key to
understanding performance,
endurance and cost differences
between SSDs, which is
essential for making an educated
purchase for your specific
enterprise application.
When NAND was invented in the
late 1980s, it was only capable
of storing one bit per cell. It
took nearly two decades of
engineering work before the first
SSD based on MLC NAND with
two bits per cell was introduced
by Samsung in 2007. Ever since
then, the industry has been
moving more and more towards
MLC technology and today,
SLC only accounts for a few
per cents of total NAND flash
output. Recently, triple-level-cell
(3-bit MLC) NAND has also been
gaining popularity, with Samsung
being the first manufacturer to
introduce it to its client SSDs in
2012 and to enterprise SSDs
two years later.
The SSD and NAND industries
have been adopting multi-
level cell technology due to the
increased cost efficiency. NAND
cost is dictated primarily by
the number of gigabytes each
wafer yields and historically there
have been two ways to achieve
increases. The first is to shrink
individual cells through traditional
lithography and multi-patterning
technologies. By making each
cell smaller, it’s possible to fit
more cells in a wafer, which
yields more gigabytes and thus
reduces the manufacturing
cost of each gigabyte. The
whole semiconductor industry
relies on lithography shrinks
to either provide lower cost
by reducing the die size, or by
adding more transistors per
die to deliver more functionality
or higher performance. While
lithography is the cornerstone
of semiconductor scaling, it has
become less cost effective in
recent years.
The second way is to add more
bits per cell. NAND flash works
by trapping electrons in an
insulated floating gate, which
creates a charge inside the cell.
SLC NAND cells only have two
states: charged (0) and non-
charged (1), whereas 2-bit MLC
NAND has four and 3-bit MLC
NAND eight to differentiate all the
possible bit outputs that two or
three bits can have.

3. Both cost scaling methods
have a negative impact on the
endurance and performance
of NAND. Making cells smaller
reduces the number of available
electrons that can be used to
differentiate between voltage
states and additionally, by
bringing cells closer to each
other and thinning the insulators
around the floating gate, the
cells become more vulnerable
to interference from neighboring
cells.
As NAND goes through program
and erase (P/E) cycles, the
tunnel oxide wears out due to
the stress caused by the strong
electric field, which is required
to tunnel electrons through the
insulating oxide to the floating
gate. This generates holes
inside the oxide structure, which
act as escape paths for the
electrons in the floating gate.
Electrons may also get trapped
in the holes during the tunneling
process. Because NAND flash
differentiates bit values based
on the voltage state of the
floating gate, electron leakage
and trapping may alter the state
from the correct one, making
the cell unreliable.
Increasing the number of bits
per cell makes matters worse
because 3-bit MLC NAND
needs to differentiate between
eight voltage states, while MLC
NAND has only four. That makes
3-bit MLC NAND less tolerant
against cell-to-cell interference
and electron leakage/
trapping, because it takes less
interference and fewer electrons
to change the state of a cell.
Similarly, 3-bit MLC NAND
requires more program-verify
iterations than MLC NAND,
as every bit is programmed
separately and the voltage
distribution of each state is
much finer, requiring a very
specific number of electrons in
the floating gate.
This all leads to 3-bit MLC
NAND having lower write
endurance and performance
compared to MLC NAND,
but read endurance and
performance are barely affected.
Because reading from NAND
works by simply sensing
the charge in the cell, the
read performance difference
between MLC and 3-bit MLC
is practically negligible in real-
world applications. Similarly,
as reading doesn’t involve a
stressful electron tunneling
process, reads induce
substantially less strain on
cells. Whereas write cycles are
measured in thousands or tens
of thousands, read cycles run
in hundreds of millions even for
3-bit MLC NAND.

4. As explained above, NAND has
traditionally been scaled by
shrinking the lithography, and in
the past decade, multiple bits
per cell have been introduced
to further scale the cost
down, but both methods are
now starting to become less
effective. These methods are
actually counteractive because
as cell size and the number of
electrons scale down, storing
multiple bits per cell becomes
even more difficult and creates
serious endurance and reliability
concerns.
To continue cost scaling in
the future, semiconductor
manufacturer have introduced
3D or Vertical NAND, stacking
multiple cells in layers. Samsung
was the first manufacturer to
begin production of its V-NAND
in 2013, with the first V-NAND-
based SSDs released a year
later.
V-NAND works by stacking
multiple layers in order to create
“cell towers.” Scaling to the
third dimension takes away
the lithography stress because
instead of making cells smaller,
cost reduction can be achieved
by increasing the number of
layers. Samsung is currently
shipping its second generation
32-layer V-NAND, and third
generation 48-layer V-NAND is
going into production in October
2015.
Because the high number of
layers brings considerable
density improvement, the cells
don’t have to be packed as
closely. Samsung has actually
moved to much larger 30nm-
class lithography, whereas
modern planar NAND is
manufactured using 15-20nm
lithography. As cells are larger
with more available electrons
and distance between cells
is greater, V-NAND is able to
provide tremendous endurance
and performance gains over
planar NAND.

5. For the majority of client
applications, 3-bit MLC NAND
provides the necessary write
endurance and performance
because consumers do not
usually write more than 20
gigabytes of data per day and
disk activity is based on bursts
of IOs. However, enterprise IO
workloads are more complicated
because there are many different
applications, each with unique
characteristics. Enterprise
workloads can, however, be
roughly divided into categories
by their write-intensity.
Read-centric workloads
include applications such
as cloud storage, media
streaming and web servers.
In these applications, data is
written once but is rarely, if
ever, modified, yet it may be
accessed by millions of people.
3-bit MLC NAND is perfect for
such applications because it
offers read performance very
similar to MLC NAND, but at a
substantially lower cost. Many
read-intensive applications
require very large amounts of
storage (consider Netflix and
Facebook as examples), but
as the data is mostly read-only,
the applications do not usually
need more than one drive write
per day (DWPD) in endurance,
making 3-bit MLC an ideal
choice because of its lower
cost.
For mixed workloads, the
choice of NAND depends on
the amount of write activity.
Because V-NAND technology
offers much higher endurance
over planar NAND, 3-bit MLC
V-NAND can be used for
mixed workloads with low
write endurance needs –
1 DWPD or less. For example,
desktop virtualization (VDI) is
typically not very write-intensive
in office environments, and
3-bit MLC V-NAND can meet
the endurance needs for such
workloads.
On the other hand, applications
such as online analytical
processing (OLAP) tend to
require higher endurance
than 1 DWPD and are hence
best served by MLC V-NAND,
which can scale to up to 10
DWPD with configurable over-
provisioning offered in the
Samsung SM863 Series.
Use cases such as real-time
financial trading and online
transaction processing are
great examples of very write-
intensive and performance-
sensitive applications. Because
these applications generate
a lot of write IOs and even a
millisecond of additional latency
may result in a lost trade or sale,
the higher endurance and write
performance of MLC V-NAND
is required for such critical
applications.
In most enterprise workloads,
the path to the lowest total cost
of ownership (TCO) is to utilize
the benefits of both 3-bit MLC
and MLC technologies through
tiering. Files that have a lot of
write activity can be kept in the
more durable MLC-based SSDs,
while files that are read-only or
accessed more infrequently can
be moved to a lower tier that is
based on 3-bit MLC SSDs.
