The ES1640dc v2 is whole-new product line developed by QNAP for mission-critical tasks and intensive virtualization applications. With Intel® Xeon® E5 processors, dual active controllers, ZFS, and fully supporting virtualization environments, the ES1640dc v2 delivers “real business-class” cloud computing data storage. The ES1640dc v2 features the brand-new QES operating system that allows almost limitless snapshots, block-level data deduplication, and thin provisioning with reclaim, assisting businesses in building the most cost-efficient VDI platform and storage for critical data. The ES1640dc v2 provides the same user experience as the current QNAP NAS and QTS system, allowing business users to enjoy the easy learning curve and quickly deploy the system, and making it ideal for small and medium businesses with budget constraints or large-scale IT divisions coping with mission-critical tasks.
- Dual active controllers, NVRAM cache, dual mini-SAS channel backup, 40GbE-ready, SAS 12Gb/s-enabled
- QES operating system which is based on FreeBSD and ZFS
- Data deduplication and compression allows hosting over 500 VDI in one chassis
- Near-limitless snapshots and SnapSync for efficient disaster recovery
- NAS and iSCSI/IP-SAN storage supporting VMware®, Microsoft® Hyper-V, KVM and advanced virtualization features
- Fully supports OpenStack® iSCSI Cinder driver
- Scalable design, over 1 PB total storage capacity
- 5 year warranty - Global warranty inclusive

Intel® Xeon® E5 dual-controller for nearly zero downtime high-availability

The ES1640dc v2 is powered by two Intel® Xeon® E5-2400 v2 processors and features dual active-active controller architecture, ensuring businesses with nearly zero downtime high availability as the standby controller can quickly take over if one controller breaks down. The ES1640dc v2 connects to the JBOD enclosure (EJ1600 v2) via the dual path mini-SAS design to sustain continuous operations even if an external JBOD cable is disconnected. Designed around redundancy, the ES1640dc v2 is the best realization of reliable enterprise storage for uninterrupted mission-critical enterprise tasks and productivity.alt

Dual controller NAS: high reliability and high availability

“Reliability” is the primary priority for mission critical business applications. The ES1640dc v2 adopts dual active-active controllers to provide the most reliable base for business IT storage.alt

  1. Dual active-active controller
    If one controller fails, the other one will immediately take over to provide high availability with the least downtime.
  2. Built-in 4 x 10GbE SFP+ ports
    Intel® XL710 network card provides four 10GbE SFP+ ports to fulfill various iSCSI/NFS/CIFS network data transmission requirements.
  3. Pre-installed dual-port 10GbE (RJ45) network card
    The PCIe slot is pre-installed with a LAN-10G2T-X550 network card that offers two 10GbE RJ45 ports. Users can replace it with a dual-port QSFP+ 40GbE NIC to provide massive data transmission potential and to simplify network cabling.
  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. 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.
  6. 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.
  7. M.2 SSD
    Stores cache data written by DRAM to ensure information is not lost if the system experiences a sudden power failure.
  8. Dual Path Mini-SAS 12Gb/s (EJ1600 v2), 6Gb/s (EJ1600) JBOD architecture
    Increases the ES1640dc v2’s potential storage capacity to over 1 PB with expansion enclosures.
  9. Intel® Xeon® E5-2400 v2 series processor
    Provides the performance required by software-defined storage and commercial mission-critical applications.
  10. 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.altalt

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.alt

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.alt
