Constant optimization of data across storage tiers
Qtier™ Technology empowers automated-tiering storage solutions that automatically moves hot data to high-performance storage tiers and cold data to lower-cost, higher-capacity drives, allowing businesses to enjoy exceptional application performance and lower TCO of storage at the same time.
|Optimal storage efficiency||High performance||Cost saving|
|Ongoing optimization of data across high-performance SSD, SAS drives and high-capacity SATA disks based on access frequency.||Improved overall system performance as active data is moved to faster storage tiers for tasks in hand.||Businesses can only buy the amount of SSDs needed, and save money on expensive Flash technology.|
|Easy to set up||Schedule||Performance analysis|
|Use QTS Storage Manager to create RAID groups for each tier, set scheduling, and it’s done.||Set Auto Tiering during off-peak times such as weekends or evenings to get the best system performance in busy hours.||Check history reports for Auto Tiering statistics to evaluate the accuracy of auto-tiering policies.|
The 15-bay, 12Gbps SAS-enabled TVS-EC1580MU-SAS-RP NAS supports 3.5” & 2.5” drives in its chassis, uniquely combining the advantages of both high-performance SSD and high-capacity HDD.
Compared with all-SSD NAS and all-HDD NAS, the TVS-EC1580MU-SAS-RP benefits organizations to enjoy exceptional application performance and lower TCO of storage at the same time. Coupled with Qtier Technology, organizations can just buy the amount of SSDs needed, and attain the highest value/performance and optimal efficiency of storage utilization.

To tackle the increasing data needs of a growing business, the scalable TVS-ECx80U-SAS series supports online capacity expansion by connecting up to eight QNAP RAID expansion enclosures (REXP-1620U-RP and REXP-1220U-RP) to flexibly expand the total storage to over 1 PB raw capacity (depending on model). It saves organizations from having to invest big at initial setup, but have budget-friendly options to enjoy more flexibility in allocating IT budgets.
You can easily implement a 3-tiered storage solution with a JBOD:
Ideal for complex virtualized environments
With Qtier Technology, QNAP NAS* provides a tiering solution that realizes the optimal storage efficiency and boosts performance, making it the best and most cost-efficient storage solution for environments like virtualization that contain dynamically-changing workloads.
The goal of auto-tiering in a QNAP NAS is to optimize the use of the storage infrastructure by simultaneously improving storage utilization and performance:
3 levels of tiered storage
Qtier offers a 3-tier configuration: ultra-high speed (SSD), high speed (SAS) and high capacity (SATA/NL-SAS) for a combination of different disk drives.
Detailed and visualized statistics for performance analysis
Historical data assists users in performance tuning and storage provisioning, enabling the accurate adjustment of auto-tiering policies.
User-defined policies for better auto-tiering efficiency
Policy-defined auto-tiering enables dynamic reallocation of data corresponding to the performance requirements of the data or applications in addition to scheduling and prioritization of data migration.
Qtier fully supports concurrent tiering and SSD caching. In this mode, Qtier constantly monitors I/O activity and keeps active data that requires small, mostly-random, read/write operations in SSD Read-only or Read-write cache and other data in the tiered storage automatically moving data between the appropriate tiers. QNAP unified and tiered storage is an intelligent, automated storage system for managing data placement to help optimize performance and cost requirements in multi-tier configurations.
Comprehensive comparison of storage technologies:
|Qtier||Full SSD||SSD cache|
|Available SSD space||Extends as needed||Extends as needed||Limited by available memory|
|Data migration method||Scheduled||No||Automatic|
|Data migration mechanism||Moves data according to access frequency||All data is in SSD storage||Replicates frequently accessed data to SSD storage|
|Application scenarios||Typically used for predictable I/O workloads such as file/web/e-mail servers and virtualization application or video editing||Typically used for applications requiring fast/intensive I/O such as databases or virtualized environments||Typically used in a highly frequent data access environment such as virtualized applications or high-resolution video or audio processing|
*Qtier is currently available in the following QNAP NAS models: TDS-x89U, TES-x85/x85U (QTS), TVS-x82/x82U, TVS-x80/x80U, TVS-x79U-SAS, TVS-x73/x73U, TVS-x71/x71U.
