Driving Up Capacity and Driving Down TCO for Cloud and Hyperscale Data Centers

The breadth and depth of Big Data is driving the universal need for higher capacities across a broad spectrum of applications and workloads. Laying the foundation for a worry-free data center, Western Digital delivers the capacity to conquer the data explosion with the Ultrastar DC HC500 series of hard drives. Built using HelioSeal technology, the industry's only fifth-generation helium platform, the DC HC500 series is designed for public and private cloud environments, where storage density, Watts/TB and $/TB are critical for creating the most cost-efficient infrastructure. HelioSeal technology is key to achieving higher drive capacities, greater reliability ratings and extreme power efficiency. The result is a lower Total Cost of Ownership (TCO) for our cloud and enterprise customers.

Solves TCO Challenges

  • High Capacity - Up to 18TB HDDs, drop-in ready for Big Data workloads

QM2 - Upgrade your QNAP NAS Experience with M.2 SSD Caching and 10G in One Card

QM2 is designed specifically to upgrade your entry and mid-end QNAP NAS system! QNAP puts 2 M.2 SSD slots (SATA or PCIe NVMe) and one 10GBase-T network port into a single PCIe expansion card. Installed M.2 SSD sticks are covered by a giant heatsink as well as a smart fan for heat dissipation which ensure operational stability and longevity. With this PCIe expansion card, you can enable SSD Caching or auto tiering while populate all your NAS bays with high capacity HDD!

Application for QM2 SSD slots:

  1. Create a volume on these SSD and use them as extra storage
  2. Enable Read Cache
  3. Enable Read/Write Cache
  4. Enable Qtier feature
  5. Boost performance in case of memory swapping

What is Qbit?

Configured system orders start here!
The selected drives are batch controlled and tested using our HDD and SSD servers. Passed drives are then installed in the NAS with Volume and RAID set. Our pre-burn testing prepares the NAS with an initial system and drive testing cycle to ensure that the integrity of the entire system is tested and passed with no issues at all.

Our stress testing (burn-test) cycle commences for a minimum of 24 hours and extends to 48 hours if requested or required. This is undertaken in order to ensure stability when used in a normal environment. These tests can include extremes of workload (constant I/O's), CPU and memory use, thermal load (heat), clock speed, or voltages, bus and connectivity components, with the primary stress testing software aiming to test stability by trying to force a system to fail. Our tests put a greater emphasis on robustness, availability and error handling heavy loads.

Once the tests are complete we QA and pack the system back into it's retail box. Then it's double boxed to protect the unit during shipping. You receive your QNAP NAS Ready To Plug 'N' Store. It doesn't get any easier. Buy your NAS from the QNAP EXPERTS at QNAP DIRECT.
