QStora

QStora is a  software-defined storage controller , which provides a high-performance  virtual storage array  in the form of virtual targets and logical volumes through standard Internet Small Computer System Interface (iSCSI) protocol. The traditional  hardware storage array  provides low latency and high availability for each logical volume, but has problems of poor horizontal scalability, high cost, and may form many "isolated data islands". That leads to high cost and low utilization of storage resource. Some traditional  distributed storage  looks quite attracting, but usually has the problems such as complex deployment, bad performance and poor stability. QStora delivers storage array in a quite different approach. QStora is a zip package, which can be easily installed on the Linux operating system of any brand and any configuration of physical servers, bare metal servers, virtual machines and even container instances. QStora is completely de...

QStora is a   software-defined storage controller , which can convert the commodity servers and their internal Hard Disk Drives (HDDs) and Solid State Drives (SDDs) to a high-performance   virtual storage array   and provide virtual targets and logical volumes through standard Internet Small Computer System Interface (iSCSI) protocol. QStora is particularly suitable for scenarios such as edge computing, hybrid cloud storage, secondary storage (backup/video surveillance), and hardware utilization enhancement. If deployed in a reliable hardware environment, QStora can even host critical workloads of the enterprises. QStora Architecture Here is the QStora Architecture. The bottom layer is the storage devices, a variety of storage media is supported, including NVMe SSD, SAS SSD, SATA SSD, SAS HDD, NL-SAS HDD, SATA HDD, and QLC SSD. These storage devices provides storage resource and are mounted to the Linux servers as disks. QStora organizes the local disks of the s...
