This paper provides guidance in architecting a cloud solution to support Network Functions Virtualization (NFV) based on VMware vCloud NFV platform. The platform dramatically simplifies data center operations, delivering enhanced agility, rapid innovation, better economics, and scale.
The values of server virtualization are well understood today. Customers implement
server virtualization to increase server utilization, handle peak loads efficiently,
decrease total cost of ownership (TCO), and streamline server landscapes.
Similarly, storage virtualization helps to address the same challenges as server
virtualization. Storage virtualization also expands beyond the boundaries of physical
resources and helps to control how IT infrastructures adjust to rapidly changing
business demands. Storage virtualization benefits customers through improved
physical resource utilization and improved hardware efficiency, as well as reduced
power and cooling expenses. In addition, consolidation of resources obtained
through virtualization offers measurable returns on investment for today’s
businesses. Finally, virtualization serves as one of the key enablers of cloud
solutions, which are designed to deliver services economically and on demand.

Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

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.

View Persona Management, and View Composer 3.0—Reference Architecture
7. The technology This solution demonstrates how to use an EMC VNX platform to provide storage
solution resources for a robust VMware View 5.1 environment by using Windows 7 virtual
desktops.
Planning and designing the storage infrastructure for VMware View is a critical step as
the shared storage must be able to absorb large bursts of input/output (I/O) that
occur throughout the course of a day. These large I/O bursts can lead to periods of
erratic and unpredictable virtual desktop performance. Users can often adapt to slow
performance, but unpredictable performance will quickly frustrate them.
To provide predictable performance for an EUC environment, the storage must be able
to handle peak I/O load from clients without resulting in high response times.
Designing for this workload involves deploying several disks to handle brief periods
of extreme I/O pressure. Such a deployment is expensive to implement. This solution
uses EMC VNX FAST Cache to reduce the number of disks required.
The solution This solution aids in the design and implementation stages for the successful
benefits deployment of virtual desktops on VMware View 5.1. This solution balances the
performance requirements and cost by using the features in the VNX Operating
Environment (OE) such as EMC VNX FAST Cache. VNX support for NFS also enables the
use of VMware NFS datastores for cost-effective and easily deployable storage for the
desktop virtualization platform.
Using desktop virtualization provides organizations with additional benefits such as:
Increased security by centralizing business-critical information
Increased compliance as information is moved from endpoints into the data
center
Simplified and centralized management of desktops

13. Thirty LUNs of 200 GB each are provisioned out of a RAID 5 storage pool configured
with 30 SAS drives. Thirty drives are used because the block-based storage pool
internally creates 4+1 RAID 5 groups. Therefore, the number of SAS drives used is a
multiple of five. Likewise, thirty LUNs are used because Automatic Volume
Management (AVM) stripes across five dvols, so the number of dvols is a multiple of
five. The LUNs are presented to VNX File as dvols that belong to a system-defined
pool.
Sixteen file systems are then provisioned out of an AVM system pool and are
presented to the vSphere servers as datastores. File systems 1 to 2 are used to store
replicas. File systems 3 to 16 are used to store the linked clones. A total of 2,000
desktops are provisioned and each replica is responsible for 1,000 linked clones.
Starting from VNX for File version 7.0.35.3, AVM is enhanced to intelligently stripe
across dvols that belong to the same block-based storage pool. There is no need to
manually create striped volumes and add them to user-defined file-based pools.
Figure 5 shows the layout of the optional CIFS file systems.
Figure 5. VNX5500 – CIFS file system layout
Thirty LUNs of 1 TB each are provisioned out of a RAID 6 storage pool configured with
32 NL-SAS-drives. Thirty-two drives are used because the block-based storage pool
internally creates 6+2 RAID 6 groups. Therefore, the number of NL-SAS drives used is
a multiple of eight. Likewise, thirty LUNs are used because AVM stripes across five
dvols, so the number of dvols is a multiple of five. The LUNs are presented to VNX File
as dvols that belong to a system-defined pool.
Like the NFS file systems, the CIFS file systems are provisioned from an AVM system
pool to store user home directories and the VMware View Persona Management

14. repository. The four file systems are grouped in the same storage pool because their
I/O profiles are sequential.
FAST Cache is enabled on both storage pools that are used to store the NFS and CIFS
file systems.
VNX shared file Two shared file systems are used by the virtual desktops—one for the VMware View
systems Persona Management repository, and the other to redirect user storage that resides in
home directories. In general, redirecting users’ data out of the base image to VNX for
File enables centralized administration, simplifies backup and recovery, and makes
the desktops more stateless. Each file system is exported to the environment through
a CIFS share.
Network layout Figure 6 shows the 10-gigabit Ethernet connectivity between the Cisco Nexus 5020
overview switches and the EMC VNX storage. Uplink Ethernet ports coming off the Nexus
switches can be used to connect to a 10-gigabit or a 1-gigabit external LAN. In this
solution, the 1-gigabit LAN through Cisco Catalyst 6509 switches is used to extend
Ethernet connectivity to the desktop clients, VMware View components, and Windows
Server infrastructure.

15. Host network All network interfaces on the vSphere servers in this solution use 1-gigabit Ethernet
configuration connections. All virtual desktops are assigned IP addresses by using a DHCP server.
The Intel-based servers use four onboard Broadcom gigabit Ethernet controllers for all
the network connections.

VNX5500 network The EMC VNX5500 in this solution includes two Data Movers. The Data Movers can be
configuration configured in an active/active or an active/standby configuration. In the
active/standby configuration, the standby Data Mover serves as a failover device for
any of the active Data Movers. In this solution, the Data Movers operate in the
active/standby mode.
The VNX5500 Data Movers are configured for two 10-gigabit interfaces on a single I/O
module. Link Aggregation Control Protocol (LACP) is used to configure ports fxg-1-0

VMware View 5.1
View Composer 3.0

The Hardware and software resources section provides more information on the
components that make up the solution.
EMC VNX series The EMC VNX series is a dedicated network server optimized for file and block storage
access that delivers high-end features in a scalable, easy-to-use package.
The VNX series delivers a single-box block and file solution, which offers a centralized
point of management for distributed environments. This makes it possible to
dynamically grow, share, and cost-effectively manage multiprotocol file systems and
provide multiprotocol block access. Administrators can take advantage of the
simultaneous support for NFS and CIFS protocols by enabling Windows and
Linux/UNIX clients to share files by using the sophisticated file-locking mechanism of
VNX for File and VNX for Block for high-bandwidth or for latency-sensitive
applications.
EMC VNX FAST VNX FAST Cache, a part of the VNX FAST Suite, uses Flash drives as an expanded
Cache cache layer for the array. The VNX5500 is configured with four 100 GB Flash drives in
a RAID 1 configuration for a 183 GB read/write-capable cache. Larger configurations
are supported for scaling beyond 2,000 desktops.
FAST Cache is an array-wide feature available for both file and block storage. This
works by examining 64 KB chunks of data in FAST Cache-enabled objects on the
array. Frequently accessed data is copied to the FAST Cache and subsequent
accesses to the data chunk are serviced by FAST Cache. This enables immediate
promotion of very active data to the Flash drives. The use of Flash drives dramatically
improves the response times for very active data and reduces data hot spots that can
occur within the LUN.
FAST Cache is an extended read/write cache that enables VMware View to deliver
consistent performance at Flash-drive speeds by absorbing read-heavy activities,
such as boot storms and antivirus scans, and write-heavy workloads such as
operating system patches and application updates. This extended read/write cache
is an ideal caching mechanism for View Composer The base replica desktop image
EMC Infrastructure for VMware View 5.1 17
EMC VNX Series (NFS), VMware vSphere 5.0, VMware View 5.1, View Storage Accelerator,
View Persona Management, and View Composer 3.0—Reference Architecture
18. and other frequently accessed user data are serviced directly from the Flash drives
without having to access the slower drives at the lower storage tier.
VSI for VMware EMC Virtual Storage Integrator (VSI) for VMware vSphere is a plug-in to the vSphere
vSphere Client that provides a single management interface for managing EMC storage within
the vSphere environment. Features can be added and removed from VSI
independently, which provides flexibility to customize VSI user environments. The
features are managed by using the VSI Feature Manager. VSI provides a unified user
experience that allows new features to be introduced rapidly in response to changing
customer requirements.
The following VSI features were used during the validation testing:
Storage Viewer (SV)—Extends the vSphere client to facilitate the discovery
and identification of EMC VNX storage devices that are allocated to VMware
vSphere hosts and virtual machines. SV presents the underlying storage
details to the virtual datacenter administrator, merging the data of several
different storage mapping tools into a few seamless vSphere client views.
Unified Storage Management—Simplifies storage administration of the EMC
VNX platforms. It enables VMware administrators to provision new NFS and
Virtual Machine File System (VMFS) datastores and raw device mapping
(RDM) volumes seamlessly within the vSphere client.
The EMC VSI for VMware vSphere product guides available on the EMC online support
website, provide more information.
VMware vSphere VMware vSphere 5.0 is the market-leading virtualization platform that is used across
5.0 thousands of IT environments around the world. VMware vSphere 5.0 can transform
or virtualize computer hardware resources including CPU, RAM, hard disks, and
network controllers to create a fully functional virtual machines that run their own
operating systems and applications just like a physical computer.
The high-availability features of VMware vSphere 5.0 along with Distributed Resource
Scheduler (DRS) and VMware vSphere® Storage vMotion® enable seamless migration
of virtual desktops from one vSphere server to another with minimal or no disruption
to the customer.
VMware View 5.1 VMware View 5.1 delivers rich and personalized virtual desktops as a managed
service from a virtualization platform built to deliver the entire desktop, including the
operating system, applications, and user data. Administrators can virtualize the
operating system, applications, and user data, and deliver modern desktops to end
users. VMware View 5.1 provides centralized, automated management of these
components with increased control and cost savings. This component also improves
business agility while providing a flexible high-performance desktop experience for
end users across a variety of network conditions. VMware View 5.1 integrates
effectively with vSphere 5.0 to provide:
Performance optimization and tiered storage support— View Composer 3.0
optimizes storage utilization and performance by reducing the footprint of
EMC Infrastructure for VMware View 5.1 18

View Persona Management, and View Composer 3.0—Reference Architecture
19. virtual desktops. It also supports the use of different tiers of storage to
maximize performance and reduce cost.
Thin provisioning support—Enables efficient allocation of storage resources
when virtual desktops are provisioned. This results in better utilization of
storage infrastructure and reduced capital expenditure (CAPEX)/operating
expenditure (OPEX).
View Composer 3.0 View Composer 3.0 works directly with vCenter Server to deploy, customize, and
maintain the state of the virtual desktops when using linked clones. Desktops
provisioned as linked clones share a common base image within a desktop pool and
have a minimal storage footprint. Because the base image is shared amongst such a
large number of desktops, it is typically accessed with sufficient frequency to
naturally leverage EMC VNX FAST Cache, where frequently accessed data is promoted
to flash drives to provide optimal I/O response time with fewer physical disks.
View Composer 3.0 also enables the following capabilities:
Tiered storage support to enable the use of dedicated storage resources for
the placement of both the read-only replica and linked clone disk images.
An optional stand-alone View Composer server to minimize the impact of
virtual desktop provisioning and maintenance operations on the vCenter
server.
This solution used View Composer 3.0 to deploy 2,000 dedicated virtual desktops
running Windows 7 as linked clones.
VMware View View Persona Management preserves user profiles and dynamically synchronizes
Persona them with a remote profile repository. This component does not require the
Management configuration of Windows roaming profiles, eliminating the need to use Active
Directory to manage View user profiles.
View Persona Management provides the following benefits over traditional Windows
roaming profiles:
With View Persona Management, a user’s remote profile is dynamically
downloaded when the user logs in to a View desktop. View downloads
persona information only when the user needs it.
During login, View downloads only the files that Windows requires, such as
user registry files. Other files are copied to the local desktop when the user or
an application opens them from the local profile folder.
View copies recent changes in the local profile to the remote repository at a
configurable interval.
During logout, only the files that were updated since the last replication are
copied to the remote repository.
View Persona Management can be configured to store user profiles in a
secure, centralized repository.
VMware View View Storage Accelerator reduces the load on the virtual desktop storage
Storage Accelerator infrastructure by caching the common blocks of Virtual Machine Disk (VMDK) files
EMC Infrastructure for VMware View 5.1 19
EMC VNX Series (NFS), VMware vSphere 5.0, VMware View 5.1, View Storage Accelerator,
View Persona Management, and View Composer 3.0—Reference Architecture
20. into memory on the vSphere hypervisors. The View Storage Accelerator feature uses a
VMware vSphere 5.0 feature called Content Based Read Cache (CBRC) that is
implemented within the vSphere hypervisor. View Storage Accelerator is enabled on a
per-desktop pool basis; when enabled the host hypervisor scans the storage disk
blocks of the virtual desktop VMDK files to generate digests of the block contents.
These blocks are cached in the vSphere hypervisor CBRC based on disk access
patterns, and subsequent reads of blocks with the same digest are served from the
in-memory cache directly. This improves the performance of the virtual desktops,
particularly during boot storms, user logon storms, or antivirus scanning storms when
a large number of blocks with identical contents are read.

21. VMware View architecture
Linked clone VMware View 5.1 with View Composer 3.0 uses the concept of linked clones to
overview quickly provision virtual desktops. This reference architecture uses the tiered storage
feature of View Composer 3.0 to build linked clones and their replica images on
separate datastores, as shown in Figure 9.
Figure 9. Linked clones and replica images
The operating system reads all the common data from the read-only replica and the
unique data that is created by the operating system or user is stored on the linked
clone. Figure 10 shows a logical representation of this relationship.

23. High availability and failover
Introduction This solution provides a highly available end user computing infrastructure. Each
component is configured to provide a robust and scalable solution for the host layer,
connectivity layer, and storage layer.
Storage layer The VNX series is designed for five 9s availability by using redundant components in
the array. All Data Movers, storage processors, and array components are capable of
continued operation in case of a hardware failure. The RAID disk configuration on the
VNX back end provides protection against data loss due to hard disk failures. The
available hot spare drives can be dynamically allocated to replace a failing disk.
Connectivity layer The advanced networking features of VNX series, such as Fail-Safe Network (FSN) and
link aggregation, provide protection against network connection failures at the array.
Each vSphere host has multiple connections to both the Ethernet networks to protect
against link failures. These connections are spread across multiple blades in an
Ethernet switch to protect against component failure in the switch.
Host layer The application hosts have redundant power supplies and network connections to
reduce the impact of component failures in the vSphere servers. VMware high
availability (HA) is configured on the cluster to help recover virtual desktops quickly
in case of a complete host failure.

28. Conclusion
Summary The features of the VNX operating environment enable EMC VNX series arrays to drive
higher storage consolidation ratios at a lower cost than was previously possible. This
reduces the capital expenditure on equipment and lowers the operational costs
required to support the placement, power, and cooling of the storage arrays.
This reference architecture provides a blueprint for a validated VMware View 5.1
virtualization solution enabled by EMC VNX storage and the VMware vSphere 5.0
virtualization platform. The solution is able to support and scale to thousands of
virtual desktops.
Next steps EMC can help accelerate assessment, design, implementation, and management
while lowering the implementation risks for an EMC infrastructure for virtual desktops
enabled by EMC VNX Series (NFS), VMware vSphere 5.0, VMware View 5.1, and
VMware View Composer 3.0.
