Dual-Controller NAS servers are fast becoming the mainstay of businesses that need high-availability, and thus enable zero-downtime. The QNAP ES1640dc series offers the ability of protecting and enabling mission critical tasks and intensive virtualization applications to work flawlessly with its dual active-active controllers, at the heart of the NAS is the incredulous intel® Xeon® E5 six-core processor family, and 32GB/64GB for main memory DIMM and 16GB write cache DIMM per controller.

As far as hardware features its stacked well, 16 hot-swappable bays x 3.5″/2.5″ SAS 12Gbps/6Gbps, or 2.5″ SAS SSD; lockable trays.  4 x SFP+ (Intel XL710-AM1) * and 2 x RJ45 (LAN-10G2T-X550) for each controller, cache is supported with M.2 2280 SSD dedicated to NVRAM. As far as maintenance is concerned this is made easy with field-replaceable unit (FRU) that is applicable to controllers, 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.

What is even more enduring is the new QES (QNAP Enterprise Storage) operating system, which is based on the FreeBSD kernel and the popular ZFS file system, which is a proven platform ideally suited for high-end enterprise applications.

There is little doubt where QNAP is heading with the ES1640dc v2 series and for under 10k for this Dual controller active-active NAS it’s a great step forward and a welcome for budget strapped IT departments that don’t get a fair share of their expenditure at budgets intervals.

Maintenance is a cinge with field replacement units and technical support is amply provided by QNAP and/or its resellers.
