Improvements to qnap qts 4.3.5 and how the envelope works

QNAP Systems, a leading provider of storage, networking and computing solutions, has officially launched its new QTS 4.3.5 operating system, which has been designed to take advantage of all the benefits of SSDs to meet the demands of the network era. high speed. This new version QTS 4.3.5 is rich in features, offers an exceptional, optimized and performance based user experience.

QNAP releases QTS 4.3.5 with over-provisioning and other enhancements

With QTS 4.3.5, users can allocate additional SSD provisioning space, from 1% to 60%, to help optimize SSD random write speeds and lifespan / endurance. A unique SSD profiling tool helps assess the best provisioning ratio based on users' target IOPS performance.

Other enhancements in this release include restoring from remotely stored snapshots, you can now write directly to the local NAS over the network without manually restoring all folders and files. This saves time and effort by streamlining operations.

From now on, volumes can be converted between thin and thick provisioning, providing maximum flexibility in allocating storage space. Also coming is QNAP's proprietary Virtual JBOD (VJBOD) technology, which is powered by iSCSI Extensions for RDMA (iSER) support of Mellanox compatible network cards, improving transmission speeds for more efficient storage expansion.

What is over-provisioning?

Over-provisioning consists of allocating a certain percentage of the free space of an SSD to help maximize the life, resistance and overall performance of the drive. This is done by providing a permanent swap space for the drive controller to handle all data traffic and storage on the drive. By ensuring this free space for the controller to move data more efficiently, the SSD no longer has to waste time preparing on-demand space to write, overwrite, and perform basic NAND maintenance tasks like garbage collection, wear leveling, and management bad blocks as the drive fills up with data under sustained workloads.

While provisioning may still be viewed by some users as an expensive waste of storage capacity, it actually offers significant benefits in smaller capacity drives and application intensive drives. For example, a 64 GB SSD at 7% over-provisioning would only leave 60 GB of storage space for the user, but there is no longer a risk of the disk becoming full, allowing the behind-the-scenes processes running without interruptions in performance to get the most out of the unit throughout its life.

Detailed benefits of over-provisioning and what benefits does it provide

• Increased Drive Performance - Over-provisioning improves random read and write performance by providing the flash controller with additional space to manage erase cycles, and ensuring that the write operation will have immediate access to a previously erased block. Sustained Performance Over Time - Over-provisioning helps keep the SSD fast even when the drive fills up throughout the read / write cycles by ensuring the controller has the space it needs to work. Increased drive endurance - By spreading the total number of writes and erases across large numbers of NAND flash blocks and pages over time, it allows the drive to maintain its workload. SSD Safeguard - Guaranteed swap space acts as a safeguard to ensure that the user does not completely fill the drive, to ensure there is enough unused capacity available on the SSD, and enough downtime to run TRIM, garbage collection, and much plus. Reduces Power Consumption: Over-provisioning allows the controller to run smoothly, and in turn requires less power from your device to do its job. Increased Reliability: As NAND flash manufacturing processes become more complex, accumulating more flash on smaller chips, over-provisioning drives are becoming common practice among manufacturers to ensure reliability as they increase usage and application expectations. Reduced time for garbage collection: Garbage collection is a background operation that requires free blocks to temporarily copy, consolidate, and store quality data while deleting invalid data blocks. Over-provisioning increases the size of the controller's workbench, giving you the additional free space needed to move data or remove worn out cells, resulting in faster execution.
