QES and ZFS (Zettabyte File System)

The QNAP Enterprise-class NAS series leverages the extensive native functionality of ZFS to ensure persistent,

reliable logical volume management, protection against data corruption, seamless capacity expansion, flexible

storage pool management, several data integrity mechanisms, unlimited snapshots, and unlimited clones. QES

also features advanced technologies for efficient space utilization including deduplication, inline compression,
and thin provisioning to maximize ROI on storage usage.

Intelligent Storage Manager

The QES Storage Manager neatly presents tools and options for managing system storage with an intuitive graphical
interface. From reviewing the system storage allocation in the Dashboard, to managing volumes, storage pools, disks
and iSCSI storage, or even the Snapshot function, the Storage Manager provides a centralized place to simplify hard
drive management and to maximize storage usage.

Dashboard

The Storage Manager dashboard provides an overview for administrators to monitor and manage storage allocations
easily. QES provides a secure and flexible way to store and manage data stored on your ES NAS. This next generation,
enterprise-grade volume management toolset offers powerful features such as storage pooling with multiple RAID
groups, thin-provisioned volumes with space reclamation, and online capacity expansion.

Storage management

IT administrators can monitor HDD allocation status for RAID groups in addition to individual HDD information.
This ensures that there are no idle HDDs, maximizing utilization of the storage resources. They can also aggregate
multiple RAID groups into a single storage pool to flexibly utilize the storage capacity. This provides further degree of
redundancy, allowing for better protection against multiple disk failures in large-capacity environments.

Enterprise ZFS NAS

Space allocation

QES supports the creation of multiple LUNs/share folders within a storage pool. View all available storage pools
with different RAID groups, share folders, and iSCSI LUNs from a single interface. This enables the expansion or
removal of current pools, setting of threshold values for capacity consumption alerts, and RAID group management.
Businesses can utilize this flexible storage capability to facilitate various business applications based on different
work groups. Storage pools and LUNs can also be extended without interrupting services.

Thin provisioning

Over-allocation enables a server to view more storage
capacity is actually available in a storage pool. This
accommodates flexible usage patterns of multiple users.
Further, the physical storage capacity is used only when
files are written by the application, improving utilization
rates.

Dynamically and efficiently, use storage spaces with

incremental allocation.

Thick provisioning

Physical storage capacity is dedicated during the initial
allocation of the storage space.

Specifically define all storage space that cannot be used by

other LUNs.

iSCSI LUN

QES supports block-level iSCSI LUN. It supports different types of configuration for server connections: 1) single LUN

Data Self-healing

Robust data integrity is one of the major characteristics that distinguish ZFS from other file systems. ZFS is designed to
protect the user's data on disk against silent data corruption caused by incidents including metadata errors and bugs in
disk firmware. Data integrity is achieved by using a checksum. When a block is accessed, its checksum is calculated and
compared with the stored checksum value. If the checksums do not match, then ZFS can heal the data using the data
storage's redundancy features.

Snapshot (local snapshot) and SnapSync (remote
snapshot replication)

QNAP Snapshot technology uses copy-on-write to record a file's status. If there is a problem with a file, blocks
containing the old data can be recovered quickly, allowing a complete snapshot version of the file system to be
restored. This greatly enhances a business's Recovery Point Objective (RPO) and Recovery Time Objective
(RTO).

Low-impact, small-sized, and user recoverable snapshots offer more benefits of storage administration compared to
traditional file copies, which are often stored as a single large data file.For example, choose to recover a file in a folder
or, recover the entire folder instantly from the easy-to-use GUI.

Intuitive interface with granular data visibility

The QNAP Snapshot provides tools in Storage Manager
to help you find specific files to recover. These tools
enable you to easily view files and folders within a
snapshot, browse through chronologically ordered
snapshots and quickly find specific files to recover.

Enterprise ZFS NAS

Snapshot clones as writeable snapshots

Clone a snapshot as a share folder or LUN for quick file access, eliminating long restore times and reserving sizeable
space for storing backups. The files in a snapshot clone can be freely edited by users.

Rsync/NAS-to-NAS integration

The Rsync (Real Time Sync) function in Backup Station automatically detect whether the system supports
Snapshots. The Rsync function takes snapshots of the volume before starting replication and then backs up
snapshots to a remote server. This greatly enhances data integrity.

VMware/Microsoft VSS integration with QNAP Snapshot Agent

QNAP Snapshot fully supports virtual machine snapshot capture on VMware and Microsoft Volume Shadow Copy
Service (VSS) deployments. Before taking snapshots, the Snapshot Agent notifies VMware or Microsoft VSS to stop
accessing iSCSI LUNs both ensuring data integrity and reducing system overhead.

SnapSync for remote snapshot replication

SnapSync enables you to replicate share folders/LUNs between different remote servers using snapshot technology as
part of a comprehensive strategy for data backup. Additionally, this approach helps to reduce storage and bandwidth
usage.

Enterprise-class disaster recovery

QES SnapSync captures snapshots and backs up local shared folders and iSCSI LUN snapshots to a specified
destination over IP. After creating a first-time full backup, SnapSync targets only changed blocks. This significantly
reduces time needed for capture snapshots.

QNAP Site Recovery Agent plug-ins for VMware Site Recovery Manager fully support remote array backup,
to ensure a comprehensive, enterprise-grade remote backup solution. If a user encounters a local computer
equipment problem or interruption in the Internet service, they can restart essential services in a short time at the
remote location. And the services can be resumed back by the primary server after successful system recovery.

1.Network environment protection

Connection management (black/white list)

Allow or deny specific IP addresses or subnets to connect
to the NAS. This increases connection safety by creating
lists of allowed and blocked IP addresses. For example,

2.Account security and system notifications

Push service

In addition to email and SMS, you can get messages sent
to your mobile devices in the event of a system failure or
other warnings. This keeps you updated with the latest
system status so that you can take immediate action to
rectify the situation and reduce the risk of data loss.

3.Protection by transmission encryption

Network transmission encryption

Advanced AES encryption ensures the security of
shared folders. Without the key, no one can access
the data in encrypted folders or files. Data transmitted
over the Internet can also be encrypted to protect data
security when using services such as FTP, WebDAV or
in File Station. QNAP NAS provides SSL connectivity,
and SSH encryption to secure data transmission and
authentication. System administrators can restrict access
to HTTPS (SSL over HTTP) encrypted connections. SFTP is
also supported for transmission security and file access.
The SSH encrypted connection provides another layer of
protection for data transmission over public networks.

5.QNAP Snapshot

QNAP's whole volume/ LUN Snapshot employs Copy-on-Write technology to record file state. If system failures occur,
you can immediately revert the system to a specific state earlier in time.

6.SnapSync

By using the SnapSync function in Backup Station, you can also back up snapshots to a remote site.

With so many layers of protection, you will never worry about data loss again.

The all-new, all-inclusive operating system

- QES 1.1.2

Engineered from the popular system architecture of the QNAP QTS OS with its simple and intuitive interface,

QES enables consolidated management of various storage systems across different product lines and a reduced

learning curve. From virtual desktop to the cloud, the QES OS on the ES1642dc / ES1640dc not only provides a
solid foundation for rapid server virtualization and applications for remote virtual desktop but also paves the way

for rapid hybrid cloud infrastructure provisioning.

Simple and intuitive QES desktop

The QES intelligent desktop allows you to easily operate the ES
convenience access to all management tasks, including launching the applications, creating desktop shortcuts and
monitoring system status.

Multitasking vs. customized desktop

The new QES system dramatically improves your
efficiency by allowing you to open multiple windows
and run multiple tasks without waiting for the previous
one to end. You can minimize running apps onto the
tool bar and switch between them. With QES's multi­desktop design, you can drag and drop a desktop icon

smart dashboard to obtain a quick view of important
information including system health, disk information
and health, resource monitoring, storage space,
scheduled tasks, device information, and firmware
information. Drag and drop dashboard functions to
the desktop to monitor them at any time. Moreover, in
the event of a critical failure (hard disk corruption, etc.)
the smart dashboard will flash and prompt a system
administrator to take immediate action to recover data
and to prevent the loss of data.

File Station manages all files from
a single management window

Just like a file explorer on your PC, File Station lets
you easily carry out common tasks operations such as
rename, copy, move, delete and compress/uncompress.
Move files from a local PC/Mac to File Station by drag­and-drop to upload the files to the NAS easily. Moreover,
enable mutual sharing on a shared folder by allowing file
upload to the folder.

Newly added sharing functions

Users can share links from their own email account with
the pre-configured SMTP server. Or they can create share
links only and copy & paste it into forums, websites, and
instant messengers for others to access them. In addition,
enable Mutual file sharing to easily share several files in
a shared folder with friends via a Share Link. By enabling

Enterprise case studies

Case 1: Deploying a remote virtual desktop infrastructure (VDI)

The QNAP ES NAS series can be deployed as robust desktop virtualization solutions that enable IT organizations
to reap the benefits of traditional server-based computing without the challenges that often accompany server­based solutions. By leveraging the benefits and advantages of VDI, IT organizations can transition away from the era
of distributed PC computing towards cloud computing and the delivery of user desktops as a service. Segregation
of operating environments from applications provides an inherent layer of security. Administrators can consolidate
and maintain a small number of core desktop images or pools that everyone can use. Implementing a standardized
solution drives down the total cost of ownership (TCO) and helps minimize the complexity and unpredictability of a
customized solution.

VDI centralizes the access control and confines corporate data to the data center and provides advanced security
measures. VDI enables organizations to extend the value of their infrastructure and desktop virtualization environments
to encompass not only desktops in the data center, but also applications and the delivery of these environments
securely to remote clients. However, the VDI administrator faces critical challenges that need to be addressed before a

｀

desktop can be made ready for the end user. One such challenge is what is termed VDI
occurs when numerous users of a VDI all attempt to boot simultaneously from a shared storage device, like at the start
of a workday, causing a substantial spike in IO traffic and putting a temporary strain on the system hosting the virtual
machines, including storage, network connectivity, and processor resources.

Implementing a read cache across an array of SSDs is the most common remedy to resolve the increased workload

1642

during workload ramp-up, and unexpected resource spikes. The QNAP ES

dc and ES
an SSD read cache to maintain the required IOPS. Additionally, where VDI creates a great deal of data redundancy
(hundreds of operating systems connect to a single clone) QES supports block-level de-duplication and compression to
further improve disk utilization and reduce power requirements, significantly reducing overall TCO.
