Description

QNAP ES2486dc ZFS 24-Bay 2U Rackmount NAS Xeon D-2142IT 96GB

QNAP ES2486dc Enterprise ZFS NAS  - 24-Bay, SAS 12G/6G, Xeon D-2142IT 1.9GHz, 96GB RAM, 7-LAN (4 SFP+ / 3 RJ45 for Each Controller), 10G-ready, iSCSI, redundant power supply, with Rail Kit

 



The ES2486dc Enterprise ZFS NAS is QNAP's first high-availability NAS with all-flash arrays and dual active controllers. Powered by an Intel® Xeon® D-2142IT 8 cores/16 threads processor, the ES2486dc supports up to 24 x 2.5-inch SAS 12Gbps SSDs and provides excellent I/O throughputs. Random write performance for all-flash arrays is further driven by the flash-optimized QES 2.1.1 operating system that comes pre-installed on the ES2486dc. The QES uses ZFS to support logical volume management; block-based inline data deduplication and inline compression reduce I/O and SSD storage consumption, which significantly extends SSD lifespan with higher price-performance ratio for all-flash storage arrays. Coupled with near-limitless snapshots and SnapSync for data protection, the QES-based ES2486dc fulfills demanding business applications, such as mission-critical file servers, virtualization servers, VDI, medium-sized data center, video streaming, surveillance storage, and efficient file backup and recovery.




- Intel® Xeon® D dual active-active controllers provide superb uptime and redundancy to ensure high availability (HA).


- Battery-protected DRAM write to cache data protection and flash read acceleration provides industry-leading random access performance.


- PCIe expandability allows for 10GbE/25GbE/40GbE adapters to increase application performance.


- Four 10GbE SFP+ ports accelerate large file sharing and intensive data transfer from virtualization or datacenter.


- Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time.


- Supports VMware® vSphere® 6.5, Windows Server® 2019 and Citrix® XenServer® 7.0 for storage virtualization. Compatible with OpenStack® cloud environments.

 

Active-Active high availability with optimal storage efficiency

In Active-Active storage system architecture, both controllers can provide a comprehensive range of services, which is different from the Active-Standby architecture of single-controller systems. An advantage of Active-Active architecture is the lack of idle computing resources. To leverage the strengths of the ES2486dc Active-Active controller architecture, QNAP recommends creating multiple storage pools and distributing ownership between both controllers to enable simultaneous output from both controllers for improved load balancing.


Active-Standby


Active-Standby single-controller system

With two HA systems you are paying twice the price, and the HA system can cause load imbalances because workloads are only processed on the active system. Moreover, a power outage can cause data loss, while network disconnections will invalidate the HA architecture.


Active-Active



Active-Active dual-controller system

Both controllers of the ES2486dc can carry traffic, along with Copy-To-Flash protection against power failure and the dual-path SAS interface design. Besides conserving computing resources, a high-speed, uninterrupted, and high-availability storage service is also provided through communication protocols such as SMB, NFS and iSCSI.


Intel® Xeon® D dual controllers optimize inline deduplication and SSD workloads

Powered by Intel® Xeon® D-2142IT 8 cores/16 threads processors, the ES2486dc delivers massive computing power to maximize inline data deduplication and inline compaction performance. The dual active-active controller architecture provides failover/failback operations since the standby controller can quickly take over if one controller breaks down. Redundant hot-swappable power supplies and cooling fans also provide businesses with near-zero downtime and high availability. The ES2486dc connects to the JBOD enclosure (EJ1600 v2) through dual-path mini-SAS design and can sustain continuous operations even if a JBOD cable is disconnected.

Multi-level cache technology with read and write support boosts storage performance

The ES2486dc simultaneously supports read caches including primary cache (L1 ARC), SSD cache as a secondary cache (L2 ARC), and write cache ZFS Intent Log (ZIL) for synchronous transactions to meet performance demands for various enterprise applications.


- Model with ZFS for Dual-controller QNAP NAS


Up to 512 GB main memory

- Each controller has eight RDIMM slots, allowing up to 512 GB memory.
- Note: The main memory will retain 8 GB through the ZIL cache.

NVRAM cache reduces the risk of losing write cache data

- If a sudden power outage occurs, the system can write cache data from the battery-protected DRAM to M.2 SSD through Copy To Flash (C2F) to ensure data security.
- Note: To ensure write cache data security, QNAP recommends replacing BBU annually. QNAP provides a one-year warranty for the BBU.

SSD Cache

Configure SSDs for SSD caching to increase IOPS performance and reducing latency for storage volume.


Use SAS or SATA SSDs flexibly within your IT budget

Although SATA 6Gbps SSDs provide high-performance affordable storage, this type of drive is unsuitable for dual-controller environments because it lacks dual-port support. By using a QDA-SA3 adapter specially designed for QNAP all-flash Enterprise ZFS NAS, a SATA 6Gbps drive can be used in the 3.5-inch SAS drive bay of the ES2486dc- allowing storage capacity expansions with cost-effective SATA drives. By installing a SATA SSD with the QDA-SA3 into the dual-controller ES2486dc, the SATA SSD can share SAS dual-port advantages to ensure a high-availability and fault-tolerant enterprise storage environment.


PCIe expansion for 25GbE/40GbE high-speed networks

The ES2486dc provides two PCIe Gen 3.0 x8 slots connected to the CPU, allowing you to install lightning-fast 10GbE/25GbE/40GbE network cards to boost virtualization, media streaming, and other bandwidth-demanding applications. Installing a Smart NIC that supports iSER can improve VMware® virtualization performance. You can also install a SAS expansion card ( SAS-12G2E ) for connecting up to seven 16-bay EJ1600 v2 expansion enclosures to seamlessly expand potential storage capacity to over 1PB, with unprecedented performance of up to 48 Gbps per host connection.


Dual controller NAS: High performance, high reliability, and high availability

The ES2486dc adopts dual active-active controllers to provide reliable mission-critical business applications in IT storage.

8 - 700W power supply

Power units are hot-swappable and the redundant power supply units in one chassis ensure continuous system uptime.


QES 2.1.1: ZFS-based, and optimized for all flash performance

The ES2486dc features the QES (QNAP Enterprise Storage) 2.1.1 operating system which is based on the simple and efficient FreeBSD kernel and ZFS file system for high-end enterprise applications. QES 2.1.1 not only provides reliable data protection, recovery, and business-class features, it is also optimized for flash storage to drive outstanding performance of all-flash storage arrays, accelerating mission-critical services and eliminate challenges in VDI environments. QES 2.1.1 also comes with Quality of Service (QoS) capabilities to ensure consistent primary storage performance in multi-application environments. The flash-optimized QES 2.1.1 continues the same user experience as the intuitive QTS, thus easy to learn for enterprise users and can be quickly implemented into existing IT infrastructures.

Unleashed SSD potential - cost-effective and agile with ultimate performance

QES 2.1.1 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-class data management and mission-critical services.

- Write Coalescing Algorithm

Transforms all random writes to sequential writes along with reduced I/O. Not only does it effectively increase random write performance for all-flash environments, but also improves SSD lifespan.

- Software-Defined Over-Provisioning

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