Answers Your Demand For Storage Efficiency
As the price of solid-state drives (SSD) becomes more favorable, the demand for high-performance storage increases. With the advantages of high IOPS and low response times, SSDs improve the performance of data center applications that require fast and consistent performance. However, as the cost per gigabyte of an SSD is still higher than conventional hard drives (HDD), it is still more economical to use HDDs to store large amounts of cold (rarely-accessed) data.
Incorporates the speed of SSDs and capacity of HDDs on one NAS system. can automatically migrate data based on how frequently data has been accessed using an industry-leading 12Gb/s SAS controller. It improves overall system performance under the most complex, mixed workloads and server applications while providing high-capacity storage for cold data.
Intelligent Data Management
Qtier, a multi-tier storage management system, automatically moves the most active data to high-performance drives while less active data is migrated to high-capacity drives. This alleviates the burden on administrators by supporting tasks of performance pre-estimation, layout design, and relocation of data according to performance and budgets.
Based on the sorting results of calculation that developed, the NAS will automatically move data blocks with higher weights to higher tier (e.g. moving data blocks from HDD RAID Group to SSD RAID Group). Here data migration and metadata updates will not interfere with normal IO; therefore, transaction-based updates will avoid problems with data integrity.
You can get the statistics of all data waiting to be processed as well as processed data in this phase. If the administrators need to do administrative tasks or there are bandwidth requirements for external connections, they can stop data migration in this phase. Furthermore, assigning weights can help adjust bandwidth allocation or alleviate congestion between external IO and internal data migration.
SSD Cache for around-the-clock acceleration
Qtier fully supports concurrent tiering and SSD caching. In this mode, 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. 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.
