SKU: ES2486AFdc-2142IT-128G
The QNAP ES2486AFdc combines an Active-Active dual-controller architecture with 24 hot-swappable 2.5-inch dual-port U.2/U.3 NVMe PCIe SSD bays. Powered by Intel® Xeon® D-2142IT processors and the ZFS-based QES operating system, it is designed for high availability, consistent low latency and enterprise data protection.
It is a 2U enterprise all-flash storage system with two independent controllers that process I/O concurrently. This configuration includes 64GB RDIMM DDR4 ECC memory per controller, for 128GB total system memory, alongside built-in 10GbE SFP+ connectivity, Copy-to-Flash protection and dual-port U.2/U.3 NVMe SSD support.
Both controllers operate simultaneously to provide redundancy, system bandwidth and computational capability.
Two independent controllers process I/O requests at the same time rather than using a traditional Active-Standby configuration.
If one controller fails, the other controller takes over the NVMe drives and network IPs through the PCIe Non-Transparent Bridge internal connection.
The supplied product information states that NAS services including SMB, NFS, iSCSI and Fibre Channel remain available without front-end reconnection.
Battery-backed Copy-to-Flash protection works with the ZFS-based QES operating system.
Each controller includes a 64GB M.2 SSD for Copy-to-Flash protection. During an unexpected power outage, the BBU helps securely write cached DRAM data to the M.2 SSD protection area to prevent data loss.
QES is based on the FreeBSD kernel and ZFS file system. The supplied product information highlights end-to-end data integrity and support for up to 65,535 snapshots for iSCSI LUNs and shared folders using Copy-on-Write technology.
Dual-port NVMe storage is designed to reduce latency and remove SAS 12Gb/s bandwidth limitations.
Each hot-swappable 2.5-inch bay supports dual-port U.2/U.3 NVMe PCIe SSDs.
The NVMe protocol reduces command queue wait times for latency-sensitive database and transaction workloads.
The supplied description states performance of over 616,000 iSCSI 4K random read IOPS and throughput of up to 15GB/s.
Built-in high-speed networking and expansion options support enterprise storage deployments.
Each controller includes four 10GbE SFP+ ports and three Gigabit Ethernet RJ45 ports, with one Gigabit Ethernet port assigned for remote management. Two PCIe expansion slots are also provided per controller.
QNAP Storage QoS is designed to deliver stable and predictable performance from a single storage pool. The ES2486AFdc can also complement the ES1686AFdc by pairing Tier 1 mission-critical all-flash storage with Tier 2 general-purpose and capacity storage.
