The ES1686dc runs the latest QES 2.1.0 operating system that supports near-limitless snapshots, Snap Sync, block-level data deduplication, & inline data compression. Whether being used as a mission-critical file server, virtualization server, VDI, medium-sized data center, video streaming, surveillance storage, & efficient file backup & recovery, the ES1686dc helps your business to achieve service-level agreements for performance & uptime.\n\n Active-Active high availability with optimal storage efficiency\n In Active-Active storage system architecture, both controllers are able to provide a complete range of services, which is different from the Active-Standby architecture of single-controller systems. The Active-Active architecture does not have the disadvantage of idle computing resources. To leverage the strengths of the ES1686dc Active-Active controller architecture, it is recommended to create multiple storage pools & distribute their ownership between both controllers. This allows simultaneous output from both controllers for better load balancing.\n\n Intel&174; Xeon&174; D dual-controller ensures high availability & failure-resistant service\n Powered by two Intel&174; Xeon&174; D processors, the ES1686dc features a dual active-active controller architecture that provides failover/failback operations as the standby controller can quickly take over if one controller breaks down. Redundant hot-swappable power supplies & cooling fans are also included to provide businesses with near-zero downtime high availability. The ES1686dc connects to the JBOD enclosure (EJ1600 v 2) via the dual-path mini-SAS design to sustain continuous operations even if a JBOD cable is disconnected. Designed around redundancy, the ES1686dc is the best realization of reliable enterprise storage for uninterrupted mission-critical enterprise tasks & productivity.\n\n Multi-level cache technology with both read & write\n The ES1686dc simultaneously supports main memory read cache (L1 ARC), SSD secondary read cache (L2 ARC), & memory write cache (ZFS Intent Log) to meet performance demands for various enterprise applications.\n\n PCIe expansion for 40 Gb E high-speed networks\n The ES1686dc provides two PCIe Gen 3 x 8 slots connected to the CPU, allowing you to install lightning-fast 10 Gb E/40 Gb E network cards to boost virtualization, media streaming, & other bandwidth-demanding applications. Installing Mellanox&174; Smart NICs further adds support for i SER for enhanced VMware&174; virtualization performance. You can also install a QM2 expansion card (QM2-4P-384) to add four additional M.2 2280 PCIe NVMe SSD slots to burst reading performance with SSD caching, or a SAS expansion card (SAS-12G2E) for connecting up to seven 16-bay EJ1600 v 2 expansion enclosures to seamlessly expand the potential storage capacity over 1PB, with unprecedented performance of up to 48 Gbps per host connection.\n\n Dual controller NAS: High reliability & high availability\n&156; Reliability&157; is the priority for mission-critical business applications. The ES1686dc adopts dual active-active controllers to provide the most reliable base for business IT storage.\n\n Leverage the 6 Gbps SAS to SATA drive adapter\n While SATA 6 Gb/s SSDs provide high-performance yet affordable storage, the lack of dual-port support makes them unsuitable for dual-controller environments. The QDA-SA adapter is designed for QNAP Enterprise ZFS NAS, & allows the use of a SATA 6 Gb/s drive in a 3.5-inch SAS drive bay
- providing the ability to expand storage capacity by using cost-effective SATA drives. By installing a SATA drive with the QDA-SA into the dual-controller ES1686dc, the SATA drive can share these SAS dual-port advantages to ensure a high-availability, fault-tolerant enterprise storage environment.\n\n QES 2.1.0: ZFS-based, & optimized for all flash performance\n The ES1686dc features the QES (QNAP Enterprise Storage) 2.1.0 operating system, which is based on the simple & efficient Free BSD kernel & the ZFS file system that has been proven through years of experience to be most suitable for high-end enterprise applications. Not only does QES 2.1.0 provide reliable data protection, recovery, & business-class features, it is optimized for flash storage & is capable of driving outstanding performance for all-flash storage arrays to accelerate mission-critical services & eliminate challenges in VDI environments. QES 2.1.0 also comes with Quality of Service (Qo S) capabilities that help ensure consistent primary storage performance in multi-application environments. Continuing the same user experience with the intuitive QTS operating system, QES provides business users with an easy learning curve for quick implementation within IT infrastructures.\n\n Unleashed SSD potential " cost-effective & agile with ultimate performance\n QES 2.1.0 features QNAP&153;s exclusive Write Coalescing algorithm that further optimizes all-flash performance in ZFS, providing a highly cost-effective all-flash solution for enterprise-class data management & mission-critical services.\n\n Deduplication & compression to maximize VDI storage performance\n In VDI environments where there could be over 90% duplicate data from OS images & applications that are spread over virtual desktops, the QES-powered ES1686dc provides businesses with the most cost-effective remote virtual desktop platform & mission-critical information warehousing.\n\n Self-Healing ensures data integrity & reliability\n Designed with a focus on data integrity, a fundamental aspect of storage security & reliability, the QES-based ES1686dc uses its end-to-end checksums to detect & correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors. If integrity violations are detected, QES automatically repairs the damage using data from the other mirror before the data is passed to applications.\n\n Streamlined remote backups with nearly limitless snapshots & Snap Sync\n The ES1686dc supports up to 65, 535 snapshots for i SCSI LUN & shared folders (if 1 snapshot is created every hour, 24 snapshots per day, then up to 7 years worth of snapshots can be created without needing to delete any) & replicates snapshots to remote servers by using the block-level Snap Sync. In the event of a primary site failure, Snap Sync assists businesses to resume essential services in the shortest possible time.\n\n Create VMware/ Windows backups for VSS-Aware applications using QNAP Snapshot Agent\n QNAP Netbak Replicator is easy-to-use & VSS-aware backup software, helping businesses to create complete backups in data centers & virtualization environments without needing additional software. To build a QNAP Snap Agent & VSS Hardware Provider operating environment, all applications (including VSS Service, Requestor, Provider & QNAP Snap Agent) can be deployed with VSS-Aware applications on the same server, & the minimal requirements are only one ES1686dc & one server for it to be operational.\n\n Compatible with VMware, Microsoft & Citrix virtualization, & supports i SER\n The ES1686dc supports VMware&174; v Sphere&174; 6.5, Windows Server&174; 2016, & Citrix Xen Server&174; 7.0 for flexible deployment & management in virtualization environments. It also supports VMware&174; VAAI & Microsoft&174; ODX to increase performance by offloading server loading for ESXi&174; server & Hyper-V&174; respectively. The QNAP v Sphere Client plug-in, Web plug-in & QNAP SMI-S provider are also supported to increase the efficiency of operations & management in virtualization applications. The ES1686dc & VMware&174; ESXi server installed with Mellanox&174; Smart NICs that support i SER can acquire i SER advantages to offload CPU workloads with boosted VMware&174; virtualization performance.\n\n QES is Open Stack Ready to explore out-of-the-box enterprise cloud services\n QES supports Open Stack&174; Cinder & Manila file sharing services. With the QNAP Cinder Driver, the ES1686dc can provide block-level storage space to virtual machines. It not only accelerates the deployment of virtual machines & enhances virtual machine image access efficiency through i SCSI, but it is also easier to integrate into commercial cloud storage platforms, providing businesses with a flexible, easy-to-use, & low-cost storage solution.\n\n\n\n\n\n\n\n Model: ES1686dc\n\n\n\n\n\n\n\n
