64 GB DDR4 ECC RDIMM per controller, expandable to 512 GB per controller across 8 slots.

24 x 2.5-inch SAS 12Gb/s bays; SATA drives can be used with the QDA-SA3 adapter.

Copy-To-Flash (C2F) with a battery backup unit protects write cache data in a power outage.

QES operating system on FreeBSD and ZFS with inline deduplication, compression and compaction.

Up to 65,536 snapshots for iSCSI LUNs and shared folders, with block-level SnapSync replication.

Two PCIe Gen 3 x8 slots per controller for 10GbE/25GbE network cards or SAS expansion cards.

Redundant hot-swappable 700W power supplies and three hot-swappable system fans.

The QNAP ES2486DC-2142IT-128G in depth

Active-active dual-controller availability

Unlike an active-standby setup, both ES2486dc controllers serve SMB, NFS and iSCSI traffic at the same time, so no computing resources sit idle. QNAP recommends creating multiple storage pools and splitting ownership between the controllers for load balancing. Dual-path SAS to TL-R1620Sdc expansion enclosures keeps operations running even if a JBOD cable is disconnected.

QES and ZFS built for flash

QES pairs the FreeBSD kernel with ZFS, end-to-end checksums and self-healing to detect and repair silent data corruption. A write coalescing algorithm turns random writes into sequential writes to improve all-flash performance and SSD lifespan, and software-defined over-provisioning lets you reserve extra SSD capacity.

Room to grow

Two PCIe Gen 3 x8 slots per controller take 10GbE/25GbE network cards or a QXP-820S-B3408 SAS expansion card, which QNAP says can connect up to seven 16-bay TL-R1620Sdc enclosures for over 1PB of potential capacity.
