4. SAS 12Gb/s hard drive

Dual-controller architecture that supports SAS 12Gb/s and SAS 6Gb/s hard drives / SSDs, providing versatile storage choices for enterprises.

5-1. NVRAM w/ Copy-to-Flash

Battery-protected DRAM write to cache data protection and Flash read acceleration provides industry-leading random access performance to benefit virtual machine deployment.

5-2. DDR3 RAM

(1) NVRAM dedicated DDR3 memory modules - supports 16GB, power required by C2F is supplied by BBU.
(2) Dual-channel DDR3 system main memory - each channel supports 16GB/32GB, providing up to 32GB/64GB total capacity.

5-3. M.2 SSD

Stores cache data written by DRAM to ensure information is not lost if the system experiences a sudden power failure.

6. Dual Path Mini-SAS 12Gb/s (EJ1600 v2), 6Gb/s (EJ1600) JBOD architecture

8. Field-replaceable unit

Field-replaceable unit (FRU) applies not only to the controllers but also to the cooling fans, power supplies, and the BBU battery pack for C2F (Copy-To-Flash), providing a cost-effective way to maintain complex systems and to replace defective parts.

NVRAM cache reducing the risks of losing write cache data

To increase random write performance and reliability, the ES1640dc v2 features NVRAM modules (DRAM Write Cache with Copy-to-flash) to protect write data. When data is written into NVRAM, there are dedicated backup battery units to protect writing to the cache, and at the same time the data is replicated to a backup controller, to achieve 100% data integrity. NVRAM-backed write cache in the dual-controller architecture presents high performance, fault-tolerant, and helps reduce flash SSD write amplification.

*To ensure write cache data safety, it is recommended to annually replace the BBU.

QES operating system combining ZFS file system

The ES1640dc v2 features the brand-new QES (QNAP Enterprise Storage) operating system, which is based on the simple and efficient FreeBSD kernel and the ZFS file system that has been proven through years of experience to be most suitable for high-end enterprise applications. QES supports dual active controller architecture and remote disaster recovery, can be directly integrated into OpenStack® cloud environments, and is designed for intensive virtualization and VDI applications with optimal performance. Continuing the same user experience with the QTS operating system, QES provides business users with an easy learning curve to quickly deploy the ES1640dc v2, and provides the best storage solution jointly with the current QNAP NAS.
