Active-Standby Architectur

Active-Standby Architecture

If the active system fails, the standby system starts up and takes over processing.

  • Requires purchasing two systems for HA, doubling the cost.
  • Causes load imbalance as only the active system processes workloads.
  • A power outage may lead to data loss.
  • Network disconnection invalidates the HA architecture, rendering it ineffective.
Active-Active Architecture

Active-Active Architecture

Both systems are active simultaneously.

  • Both controllers handle traffic, optimizing workload distribution.
  • Copy-To-Flash protection safeguards data against power failure.
  • Dual-path SAS interface ensures seamless connectivity.
  • Efficient resource utilization, reducing computational waste.
  • High-speed, uninterrupted, and high-availability storage service.
  • Supports multiple communication protocols: SMB, NFS, and iSCSI.

Intel® Xeon® D processors bring high performance and efficiency

Powered by two Intel® Xeon® D processors, the ES1686dc R2 features a dual active-active controller architecture that provides failover/failback operations as the standby controller takes over if one controller breaks down.

Multi-level cache technology

Multi-tier caching Multi-tier caching

The ES1686dc R2 simultaneously supports main memory read cache (L1 ARC), SSD secondary read cache (L2 ARC), and memory write cache (ZFS Intent Log) to meet performance demands of various enterprise applications.

RAM Expand main memory up to 512GB

Both controllers have eight RDIMM slots, allowing for up to 512GB memory.

The main memory will retain 8GB for use by the write cache.

NVRAM NVRAM

In the event of power failure, the system can write cache data from the battery-protected DRAM to M.2 SSD through Copy To Flash (C2F) to ensure that data is not lost.

To ensure write cache data safety, it is recommended to annually replace the BBU. QNAP provides one-year warranty for the BBU.

PCIe Gen 3 slots

The ES1686dc R2 provides two PCIe Gen 3 x8 slots per controller connected to the CPU, allowing you to add additional functionality to meet growing workload and business requirements.

Self-healing ensures data integrity and reliability

Designed to ensure data integrity, the QES-based ES1686dc R2 uses end-to-end checksums to detect and correct silent data corruption caused by hardware defects, firmware bugs 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.

Unleashed SSD potential – agile and cost-effective for the ultimate performance

QES 2.2 features QNAP’s exclusive Write Coalescing algorithm that further optimizes all-flash performance in ZFS, providing a highly cost-effective all-flash solution for enterprise data management and mission-critical services.

QNAP all-flash solution

Write Coalescing

Transforms all random writes to sequential writes along with reduced I/O. This not only increases random write performance for all-flash environments, but also improves SSD lifespan.

Pool over-provisioning

Users can allocate additional over-provisioning for SSDs (from 1% to 60%) and Storage Pools (from 1% to 40%) for a constant performance boost of over 100%.

Deduplication and compression maximizes VDI storage performance

In VDI environments where there could be over 90% duplicate data from virtual desktop OS images and applications, the QES-powered ES1686dc R2 provides businesses with the most cost-effective remote virtual desktop platform and mission-critical information warehousing.

Inline data deduplication

Block-based data deduplication optimizes storage usage and significantly decreases storage capacity requirements.

Inline compression

Shrinks data to reduce storage I/O workloads for improved performance. In VDI, deduplicated virtual desktops are easily cached to achieve optimal virtual desktop performance.

Inline compaction

Especially helpful for increasing SSD storage utilization efficiency when highly repetitive data or massive small files (such as transaction logs of banks or e-commerce) are generated. It delivers higher cost efficiency of all-flash storage systems.

Deduplication helped us achieve our primary goal of increasing storage capacity more efficiently.

Real-time SnapSync ensures minimal RPO with real-time disaster recovery

Real-time SnapSync ensures that both the primary and secondary NAS maintain identical data. When data is written to the source, it is immediately written to the destination. If the primary NAS goes offline, IT staff can simply adjust the privilege settings of the secondary NAS to ensure continuous operations. SnapSync provides the strongest support for nonstop business operations and helps users to reduce the risk of data loss.

Real-time SnapSync
Business Continuity

Business Continuity

Copy-on-write technology makes QES snapshot creation almost instantaneous without affecting ongoing data writes. SnapSync supports incremental backups, real-time deduplication, and compression. The source ES1686dc R2 performs deduplication before compressing the metadata to reduce synchronized data and save bandwidth.

VMware SRM

VMware SRM

SnapSync supports VMware Site Recovery Manager (SRM) that offers enterprise-class remote backup and disaster recovery solutions for virtual applications. With the Storage Replication Adapter (SRA) for SRM, operation overheads of the ESXi® server can be offloaded to a QNAP NAS to accelerate and simplify virtual machine backup/restore.

Compatible with VMware, Microsoft and Citrix virtualization

The ES1686dc R2 supports VMware® vSphere®, Windows Server®, and Citrix XenServer® for flexible deployment and management in virtualization environments.

Learn More: Storage for Virtualization

VMware

Reliable, high-performance storage for virtualization

The ES1686dc R2 supports block-based iSCSI LUN as a reliable, high-performance, and affordable storage solution for mainstream virtualization environments. It supports VMware® VAAI and Microsoft® ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively.

Learn More

Supports iSER for Improved VM Performance

The ES1686dc R2 supports iSER, combining iSCSI and RDMA (Remote Direct Memory Access), which can bypass general network drivers, the socket layer, and to directly enter memory buffers of the server and storage. Response time is also reduced to ensure service quality of the NAS.

Build an affordable Fibre Channel SAN environment

Common Fibre Channel Storage Area Networks (SAN) devices are often costly. By installing QNAP dual-port 16Gb/32Gb Fibre Channel expansion cards in the ES1686dc R2, you have more budget-friendly options to add a NAS to a SAN environment. You can set a Fibre Channel Target using the iSCSI & Fibre Channel app. Moreover, the LUN Masking and Port Binding features provide an additional layer of data security.
