{2jtab:Features} For 6Gbps SAS to SATA hard disk / SSD adapterSATA 6Gb/s interface SSDs provide a high-speed and economical storage solution, but are limited by the fact that SATA SSDs do not support dual-homing and therefore cannot be used in dual-controller environments. Designed for the QNAP Enterprise ZFS NAS, the QDA-SA hard drive adapter converts SAS signals into hard drive bays for SATA 6Gb/s connectors. With the QDA-SA's SATA HDD/SSD for dual-controller ES1686dc, SATA SSDs also feature SAS Dual-port fault tolerance, providing powerful support for high availability applications and helping organizations enjoy economical and flexible Save the configuration plan. New QES 2.1.0 operating system: running ZFS file system, Flash random write performance is more excellentThe ES1686dc is equipped with a new generation QES (QNAP Enterprise Storage) 2.1.0 operating system based on the FreeBSD core and featuring a ZFS file system that is optimal for high-end enterprise applications, demonstrating high performance and robust data protection and disaster recovery mechanisms. And a variety of enterprise management features. QES 2.1.0 is based on the flash-optimized architecture, especially for all-flash (All Flash)-configured storage arrays, helping organizations accelerate the speed of business-critical applications and effectively overcome remote virtual desktops ( VDI) Challenges in the application environment. QES 2.1.0 also supports QoS management capabilities to provide performance guarantees in a multi-user environment. The QES operating system continues the QTS user experience, helping enterprise users enjoy the lowest learning curve and fastest deployment speed, and seamlessly connect to the current QNAP NAS. Unleash the potential of SSD - fine, flexible, and breakthroughQES 2.1.0 uses QNAP's exclusive Write Coalescing algorithm to optimize the read and write performance of the Full Flash storage environment in the ZFS file system, providing more enterprise-level data management and mission-critical operations. A cost-effective full flash storage solution. Write aggregation algorithmThe scattered and randomly written data can be sequentially sorted and merged into the block, thereby reducing the number of I/Os, which not only significantly improves the write performance of the full flash configuration, but also helps the durability and service life of the SSD. Software-defined reserved space (Software-defined Over-provisioning)Users can flexibly set 1% ~ 60% of SSD reserved space and 1% ~ 40% of storage pool reserved space according to demand, so that continuous write performance can grow by more than 100%. Data deduplication, compression and compaction to create an enterprise application environment with more than 500 VDIsRemote virtual desktop (VDI) applications that store large amounts of the same operating system and applications simultaneously have incredible data repeatability (up to 90% or more).

Self-healing error blocks to ensure data correctness and availabilityES1686dc supports the self-healing capability of Silent Data Corruption, which allows Checksum for all data blocks. If the static data is damaged due to hardware (for example, broken transmission line), driver, or Metadata error, the next time you read this block, the backup data will be automatically repaired due to the inconsistency of Checksum results. Correctness. Nearly unlimited snapshots sync with SnapSync snapshots to create an impeccable disaster recovery mechanismThe ES1686dc supports snapshots of iSCSI LUNs and shared folders with up to 65,535 snapshots (assuming one snapshot per hour, 24 per day, which can be maintained for 7 years without deletion!). The established snapshots can be backed up to the remote through the block-based SnapSync snapshot synchronization function. When a disaster occurs, comprehensive and efficient snapshot synchronization allows the enterprise to quickly restart important services in a remote location in a short time Remote backup, data restoration is not interruptedQES's snapshot service uses Copy-on-Write technology to take snapshots almost instantaneously without affecting data writes. Accelerate offsite backup with SnapSync's differential backup. SnapSync also supports instant data deletion and compression. Before synchronization, the source ES1686dc first deletes the data and compresses the metadata, which greatly reduces the amount of data in the synchronous backup and reduces the network bandwidth requirement Integrate VMware SRMQES's SnapSync technology integrates with VMware Site Recovery Manager (SRM) to provide a remote backup and disaster recovery solution for high-end enterprise-class virtualized environments.
