Nearly unlimited snapshots are synchronized with SnapSync snapshots to help organizations build recovery plans in the shortest amount of time.
Complete VMwareR vSphereR 6.5, Windows ServerR 2016 and CitrixR XenServerR 7.0 virtualized storage applications with support for OpenStackR block storage.

Active-Active balances storage performance with high availability

Dual Active Controller (Active-Active) The storage system architecture with two controllers providing services simultaneously. Unlike the single-ended Active-Standby architecture, which has only a single controller activity, the dual-active architecture has no shortcomings of computing resources being idle. In order to fully utilize the advantages of the ES1686dc dual-active controller architecture, it is recommended that users can create multiple storage pools and evenly distribute the storage pools to two controllers, so that the advantages of dual-active controller architecture load balancing can be realized.

Active-Standby single-ended backup architecture
A high-availability system requires twice the cost of the system and hard drive. The data load is also handled only on Active systems, resulting in unbalanced system load. In addition to the risk of loss of power outage data, network disconnection will also invalidate the highly available architecture.

Active-Active Dual Active Controller Architecture
There is no need to buy two systems at twice the cost. Both ES1686dc controllers provide data access services with C2F (Copy-To-Flash) and dual-path SAS interfaces with power-down data protection. In addition to not wasting valuable computing resources, it can also provide high-speed, high-availability storage services through SMB, NFS, iSCSI and other communication protocols.

IntelR XeonR D dual-control architecture for highly available services with near-stop performance

Built for the data center, the ES1686dc is equipped with two high-performance IntelR XeonR D processors that support dual active-active. When one controller fails, the other controller can take over immediately and automatically. Fault controller all work; equipped with auxiliary heat exchange components (including controllers, fans, power supplies, hard drives) and controllers with Failover / Failback functions, providing enterprises without High availability for downtime. The ES1686dc and JBOD storage expansion unit ( EJ1600 v2 ) also supports the dual-loop architecture of the Mini-SAS Dual Path redundancy design. Even if one of the JBOD cables is damaged, the system can be transported normally. ES1686dc's multi-protection mechanism helps companies through every critical moment.

Multi-layer cache with both read and write: up to 512 GB of main memory with SSD read/memory ZIL write cache

ES1686dc supports both main memory read cache (L1 ARC), SSD read cache (L2 ARC), and memory write cache (ZFS Intent Log) to meet the performance needs of different enterprise applications.

Memory can be expanded to 512 GB

The single-sided controller provides a total of eight RDIMM slots for memory capacity up to 512 GB.
Note: The system will retain 8GB of memory for use as a cache.

M.2 SSD cache

Built-in 2 M.2 SSD ports, support PCIe Gen3 x4 or SATA 6Gb/s SSD, flexible configuration SSD cache, improve data read and write cache performance.
Note: Shipment does not contain M.2 SSD

C2F implements data write zero risk

The system memory is equipped with a backup battery unit (BBU) protection, and the Copy To Flash (C2F) cache ensures that the data in the memory and the ZFS Intent Log (ZIL) can be retained when the system is powered off and after the power is restored. Reply to avoid data corruption.
Note: To ensure data writing security, it is recommended to replace the BBU once a year.

PCIe flexible expansion, immediately upgrade 40GbE rapid experience

The ES1686dc features two PCIe Gen3 x8 expansion slots from the CPU to flexibly configure 10GbE / 40GbE NICs for your needs, meeting the high-speed network requirements for virtualized applications, streaming video, and high-bandwidth business services; installing the MellanoxR SmartNIC network The road expansion card also supports the iSER offload capability. Install the QM2-4P-384 expansion card to add four additional M.2 2280 PCIe NVMe SSD slots for faster read speeds. SAS-12G2E can also be installed to cascade up to 7 units. EJ1600 v2 storage expansion device with hard disk , with 48Gb/s high-speed data transmission performance, can expand the total storage space by more than 1 PB without stopping the machine.

Key enterprise-level dual-control backup design: high-speed, uninterrupted, high-availability storage services

"Reliability" is the number one priority for key enterprise applications. With dual active controllers, the ES1686dc provides instant hardware backup with virtually no downtime and is the cornerstone of critical enterprise storage.
