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

or multiple LUNs per iSCSI target and storage pool to reduce overhead and improve overall read/write performance.

) multiple iSCSI targets for a single LUN. Deploy block-level iSCSI LUN in a

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.

Robust RAID-Z data protection on ZFS

RAID-Z outperforms traditional RAID technology with better efﬁciency in handling petabyte-size data collections. And when combined with the copy-on-write transactional semantics of ZFS, write hole errors can be eliminated.
