Product Information

Full Description

Details

The ES1640dc is a product line developed by QNAP for mission-critical tasks and intensive virtualization applications. With powerful processors, dual active controllers, ZFS, HPE Helion compatibility and fully supporting virtualization environments, the ES1640dc delivers "real business-class" cloud computing data storage. The ES1640dc features the QES operating system that allows almost limitless snapshots, block-level data deduplication, and thin provisioning with reclaim, assisting businesses in building the cost-efficient VDI platform and storage for critical data. The ES1640dc 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, 40 GbE-ready, SAS 6 Gb/s-enabled
  • QES operating system which is based on FreeBSD and ZFS
  • Data deduplication and compression allows hosting over 200 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, and compatible with HPE Helion
  • Scalable design, up to 1 PB total storage capacity
  • E5 dual-controller for nearly zero downtime high-availability
    The ES1640dc is powered by two 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 connects to the JBOD enclosure via the dual path mini-SAS design to sustain continuous operations even if an external JBOD cable is disconnected. Designed around redundancy, the ES1640dc is a great realization of reliable enterprise storage for uninterrupted mission-critical enterprise tasks and productivity.
  • Dual controller NAS: high reliability and high availability
    "Reliability" is the primary priority for mission critical business applications. The ES1640dc adopts dual active-active controllers to provide the reliable base for business IT storage.
  • NVRAM cache reducing the risks of losing write cache data
    To increase random write performance and reliability, the ES1640dc features NVRAM modules 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.
  • QES operating system combining ZFS file system
    The ES1640dc features the 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 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, and provides a great storage solution jointly with the current QNAP NAS.
  • ZFS - the file system for business data storage
    The ES1640dc features ZFS, a combined file system and logical volume manager, to support various advanced functions for high-end enterprise storage, including powerful storage expansion, flexible storage pools, simplified management, high-performance SSD cache, nearly limitless snapshots and cloning, data deduplication, in-line compression and thin provisioning with reclaim for optimized utilization for virtual machine storage. ZFS is designed with a focus on data integrity, and uses its end-to-end checksums to detect and correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors, effectively protecting user's data.
  • Strong disaster recovery made by nearly limitless snapshots and SnapSync
    The ES1640dc supports up to 65,535 snapshots for iSCSI LUN and shared folders. When executing a remote snapshot backup, it only needs to transfer changed data, and can use deduplication and compression to significantly reduce the amount of transferred data. The ES1640dc can provide remote backup SnapSync for snapshots at the shortest interval of every five minutes, fully supports VMware vCenter Site Recovery (SRM) technology, provides Storage Replication Adapter (SRA) for SRM, and provides enterprise-class remote backup & disaster recovery solution to fulfill business continuity.

Well, this is disappointing - this product has sold out. Fear not though, more may be on order or we may be able to source it for you.

Are we out on price?

We check our prices daily against a wide range of competitors to try to bring you the best deal. However, if you've spotted a better price offered by one of our competitors, please let us know and we'll do our very best to match it.

Price Match Challenge

Is the advertised price & availability genuine?

The IT sector is littered with companies who don't hold stock. Their websites advertise products that are sourced from third party suppliers. Pricing and availability data on such sites is typically retrieved from files or feeds which are often not refreshed regularly enough. The result? Cancelled orders, long lead times and disgruntled customers.

King of Servers is a major stockholder with full transparency into our stockholding and pricing. Our website is refreshed on a 15-minute cycle 24/7 so the pricing and availability you see online is both accurate and reliable.

We recommend you double check a cheaper price elsewhere is accurate and based on physical stock that can be shipped immediately before placing your order.

Do they really have the product in stock?

We show true stock counts on our website, not woolly messages like ‘in stock' or ‘available to order'. Stock levels are updated every 15 minutes 24/7 so you can see exactly how many units we have sat in our warehouse available for immediate despatch.

And speaking of shipping, did you know we offer same day deliveries? You can choose this or other timed services during checkout on our website or contact our sales team for a quote. Handy when you need the goods in a hurry!

Do they specify product condition?

Most web stores fail to specify the stock condition of the products they advertise for sale. It seems reasonable to assume that all products are brand new, unused units supplied in the sealed, original manufacturer packaging and protected by the full warranty but this isn't always the case.

A heavily discounted price can be a sign that the product in question may be a used or refurbished unit. Open/damaged box and ‘ex demo' units are also rife in the marketplace and warranty cover on such goods will be variable so it's wise to check what you're getting before committing to any purchase.

King of Servers displays the product condition on all our product pages. As well as detailing what the condition means, we specify the level of warranty condition allowing you to make an informed buying decision.

Ensure you compare like for like when shopping around for prices online.

Is the product covered by warranty?

All brand new products come with a full manufacturer warranty, right? Not always; it depends where the products were sourced from. You may have heard of the grey market or parallel imports? Manufacturers often stipulate the geographical regions in which their products are designated for sale. Unscrupulous suppliers seek to source goods from outside of these regions at cheaper costs which they pass on via cheaper prices. The downside is that the manufacturer might not honour the warranty in the event of a support call. Grey kit does not qualify for warranty support and if it fails, you could be significantly out of pocket.

All products offered for sale at King of Servers are sourced from legitimate channels and are covered by warranty. For added peace of mind, we can supply serial numbers up front which can be validated on the manufacturer's website to ensure warranty cover is in place prior to purchase.

Ask any potential supplier if they can supply serial numbers ahead of purchase. Any legitimate stockholder who has sourced the goods from the proper channels should be able and happy to do so.

Is the competitor trustworthy?

Look beyond the price and establish whether the company behind the product is a bona fide organisation that you can return to should you encounter issues down the line. This is particularly important if you've never heard of them before. It's relatively easy to set up a web shop nowadays which makes it difficult to differentiate between a one-man band operating out of a home office and a well-established, reputable bricks and mortar business. Sales T&Cs, returns policy and aftercare service are probably important areas for you to consider.
