Introduction to the QNAP ES NAS
The QNAP ES NAS is a high-availability enterprise storage system designed to support dual storage
controllers and simplify management efficiency in a budget-friendly manner. The ES NAS is suitable for a
wide range of workloads in enterprise cloud environments and is a best-of-breed multiprotocol storage
in an iSCSI SAN environment. From the advanced ZFS-based QES NAS operating system and near-
unlimited number of snapshots to its native inline file compression and deduplication support, the ES
NAS is equipped with enterprise-class hardware and software. QES is also based on the user-friendly
QTS NAS operating system, which enables consolidated management of various storage systems across
different product lines and reduces the learning curve of users. In addition, the ES NAS can
accommodate any number of SSDs. Implementing a read cache across an array of SSDs is the most
common method to accelerate application performance and resolve increased workloads during
workload ramp-up, and unexpected resource usage spikes.
The dual controller is powered by an Intel ® Xeon® E5 processor with 96GB RAM (48GB per controller).
This superior computing power enables faster movement of data between different components of the
system. As a result, the read and write performance for I/O requests is also improved. The employment
of BBU and NVRAM protects the data in the DRAM if a power supply failure should occur. The cable-less
design throughout the entire system assists in heat dissipation and improves overall reliability.
Furthermore, the Field Replaceable Unit (FRU) design in many of its hardware components allows you to
replace damaged parts - including storage controllers, fan modules, power supply units, and battery
backup units (BBU) - to attain a higher level of system serviceability and reliability.
