Customer Needs

The world of modern data storage solutions includes a broad spectrum of demands for implementations from HDD-based large-capacity storage setups up to high-performing All-Flash types of storage. Solution providers are challenged to develop solutions to meet different requirements, for instance:

  • Scalability
  • Cost-efficiency of HDDs
  • High performance of NVMe SSDs
  • Balance between TCO and performance

The combination of Western Digital hardware, ATTO adapters, and Open-E JovianDSS advanced caching features has been certified together and it is proved that the solution enhances the crucial parameters of the whole data storage solution based on HDDs.

Hardware and Software Specification

The solution consists of the following hardware elements:

  • ATTO ExpressSAS® GT HBAs (H1244GT) - a 4-Port External 4-Port Internal 12Gb/s SAS to PCIe 4.0 Host Bus Adapter built to handle the scalability and availability needs for the next generation of data processing.
  • ATTO FastFrame™3 100GbE NICs which are suitable for a wide variety of high-performance applications and provide a high-quality and high-performance experience. ATTO NIC supports the Ethernet standard in a single- or dual-port configuration.
  • Western Digital Ultrastar® Data60 Storage Platform, which provides up to 1.3 PB of raw storage using DC HC570 22TB CMR HDDs in a compact and efficient form factor. Ultrastar® Data60 addresses the demanding storage needs of large enterprise customers, as well as cloud service providers, requiring dense, shared HDD.
  • Western Digital Ultrastar® TB 3,5” SAS HDD Family, which enable an incredible capacity to maximize data storage, especially in footprint- and power-constrained environments. Performance-optimized for heavy application workloads
  • Western Digital Ultrastar® DC SN840 1.6 TB NVMe SSD, performance-optimized SSDs that target the cloud computing and enterprise workloads that require low latency and high availability of data.

As for the software, the whole system was powered by the ZFS-based Open-E JovianDSS. With Open-E JovianDSS users can achieve advanced levels of data protection since not only a High Availability clustering to ensure zero-downtime data accessibility can be utilized but also consistent data snapshots that can be stored both locally and remotely on the external backup machine. This way users can build their Business Continuity strategy against all the threats such as hardware failures, power outages, human errors, ransomware attacks, natural disasters, and much more.


The technology used in the Western Digital, ATTO, and Open-E joint solution takes full advantage of the hardware components: the high capacity of the HDDs and the super-high performance of the NVMe SSDs that build an appliance that can meet even the most demanding requirements of the data centers and enterprise customers in terms of centralized NAS filers, media postproduction, CCTV, backup servers, or even virtualization, and more.
