With the Windows Flash Array family, Zstor offers a very versatile, high performance storage system that can be seamlessly integrate into new and existing IT environments. Especially where a high input-/output load is requested, the Windows Flash Array of Zstor plays out its special features and represents more than 1.4 million IOPs in particular in the field of databases. With a data transfer rate up to 10 GB/s also large files can be quickly and easily transferred to the central servers. The Zstor AF224 is optimized for use in Microsoft Windows, HyperV, Linux, and VMware environments. The main features are:

  • More than 1.400.000 IOPs with Enterprise SSDs
  • up to 10 GB/s real data transfer
  • 4,8 - 38,4 TB total capacity
    (2 - 16 TB usable high performance net capacity)
  • Internal data transfer via SAS 12 GB/s
  • Two hot swap nodes, each with two Intel XEON processors out of Haswell family
  • 128 / 256 GB RAM DDR4 per node
  • 10 Gb-Ethernet-, IB- or FC-interfaces
  • RDMA support for fast data access
  • Redundant high efficiency 80+ Platinum PSUsAF224a front
  • Compact chassis in 2U rack mount
  • Hot swap carriers for SSDs
  • Expansion up to 115 ZB total capacity
    via JBODs and SAS 12GB/s external interfaces


Highly available SSD Array

With the AF224 Zstor has developed a high-availability storage system based on Microsoft Windows Server 2012 R2 and consistently optimized the technical possibilities of storage spaces with powerful hardware components. Through the use of solid state disks of the enterprise-class in the fastest 12G-SAS-Technologie the AF224 uses not only an existing potential in terms of IOPs, but also in terms of latency. In addition to low response times, the Windows Flash Array of Zstor realized also the transfer of large files up to 10 GB/s. Performance is achieved by use of two hot swappable server bays (2 node cluster), each of them is equipped with two of the latest Intel server processors. That also a sufficient memory in DDR4 technology is installed, is almost obvious.

"Storage Spaces" realized as it‘s best

The Zstor Windows Storage Array fits seamlessly in the Microsoft server world. Thanks to Windows Server 2012 R2 features can took advantage of the storage spaces and the connections to the server are done through proven protocols. Particularly, the AF224 is suitable for the virtual world of the HyperV, because here it can be set as scale-out-file-server (SoFS) and makes high-performance space available to virtual machines or SQL databases.


   Ideal for Data Center

Ease of deployment, operation and scalability are essential requirements of modern large-scale data centers, who request typically fast servers and high performance data access. The compact design in 2U rack mount and the ease of use and integration into existing IT structures suggest the Zstor Windows Flash Array for use in data centers. The Zstor AF224 family fits into today's requirements also with regard to the acquisition and operating costs, because the system can be extended at a later date through external 12G SAS interfaces in addition to a very good price/performance ratio. As a result the systems therefore grows with future customer needs.
