QNAP ES2486AFdc
Extreme All-Flash Performance. An NVMe High Availability Storage Solution Built for Mission-Critical Environments.

Overview:

The ES2486AFdc is QNAP's first enterprise-grade storage combining an Active-Active dual-controller architecture with a U.2 / U.3 NVMe all-flash design. It shatters the performance bottlenecks of traditional High Availability (HA) systems constrained by SAS interfaces, utilizing a PCIe Gen4 direct-connect architecture to deliver microsecond-level ultra-low latency and millions of IOPS throughput. Powered by the ZFS-based QES operating system to ensure zero data loss, it is the ultimate foundation for enterprise virtualization environments, VDI desktop deployments, and core databases.

• Intel® Xeon® D multi-core processor (Dual Controller)
• 24 x U.2 / U.3 NVMe PCIe Gen4 drive bays, supporting dual-port SSDs
• Built-in 4 x 10GbE SFP+ network ports
• Supports 1PB+ logical storage capacity

Features:

Active-Active Dual-Controller Architecture

The ES2486AFdc features two completely independent controllers that process I/O requests concurrently (Active-Active), rather than the traditional Active-Standby configuration. Each controller is powered by an Intel® Xeon® D-2100 series processor and supports up to 512GB of DDR4 ECC memory, delivering robust multitasking computational power.

Making All-Flash More Reliable: Write Coalescing and Disaster Recovery

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.

PB-Level Dual-Controller SAS Storage Scalability

Achieve PB-level storage capacity by connecting up to seven QNAP expansion enclosures, and utilize Dual-path connections to ensure services continue running seamlessly even if a single node fails.

Perfect Match for QNAP Enterprise Switches

If you plan to enable iSER (iSCSI Extensions for RDMA) to lower CPU workloads and latency, QNAP's QSW series switches support PFC (IEEE 802.1Qbb). This allows pausing only traffic of "specific priorities" (such as storage traffic) without affecting other business operations, creating a true Lossless Ethernet environment and preventing packet loss from degrading RDMA transmission performance, thereby fully unleashing its high availability and extreme performance.

Adaptable to Diverse Application Scenarios

Application Scenario	ES2486AFdc Advantages
Virtualization Servers (VMware / Hyper-V / Proxmox)	Supports VAAI and ODX offload transfers; iSER (iSCSI over RDMA) lowers CPU loads. The dual-controller architecture guarantees zero VM downtime.
VDI (Virtual Desktop Infrastructure)	Powerful inline deduplication saves massive amounts of SSD space; high NVMe IOPS effortlessly handles "Boot Storms" when hundreds of employees boot up simultaneously.
Media & Entertainment (M&E)	Ideal for collaborative online editing of 4K/8K high-resolution videos, with 25GbE bandwidth satisfying multiple workstations accessing media assets concurrently.
Database (SQL / Oracle)	The ultra-low latency of NVMe drastically shortens database query times and transaction processing times.

Hardware Specifications:

Note: Use only QNAP memory modules to maintain system performance and stability. For NAS devices with more than one memory slot, use QNAP modules with identical specifications and refer to the hardware user manual to install compatible QNAP memory modules.
Warning: Using unsupported modules may degrade performance, cause errors, or prevent the operating system from starting.
QNAP reserves the right to replace partial parts or accessories if the original is no longer available from its manufacturer/supplier. Any replacement would be fully tested and verified to meet strict compatibility and stability guidelines and will deliver identical performance to the original.
