What is QStora?

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 servers into fully distributed storage pools, and provides virtual targets and logical volumes as block storage services for upper-layer applications through standard iSCSI interfaces. The client supports both Windows and Linux. With the help of iSCSI initiator, the client can connect to the servers of QStora and use the logical volumes provided by QStora as the local disks, to provide storage resources for the applications deployed on client.

The use of QStora makes the management of the storage simple and easy, while simultaneously providing a very powerful, highly flexible, reliable and fast storage solution.

Introduction to the basic architecture and operation of Internet Small Computer Systems Interface

Image
 iSCSI is an acronym for Internet Small Computer Systems Interface, an Internet Protocol (IP)-based storage networking standard for linking data storage facilities. iSCSI works on top of the Transport Control Protocol (TCP), and provides block-level access between the iSCSI initiator and the storage target by carrying SCSI commands over a TCP/IP network. iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances. iSCSI can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet, and can  enable  location-independent data storage and retrieval. Overview of the overall architecture iSCSI   is a remote mapping technology that maps a storage device on a remote server to the local area and presents it as a block device (which can be thought of as a disk). From the perspective of the normal user, the mapped disk is no different from the locally connected disk. This mapping is based on the SCSI protocol, whi

What is MPIO and how to use it?

M PIO is an acronym for MultiPath Input Output. This is a framework designed to configure load balancing and failover processes by providing multiple logical paths between storage devices and the server. The logical paths can be created through redundant physical components like buses, controllers, switches or bridge devices. Should one or more controllers, ports or switches fail, the server can route the I/O through an alternate path, the remaining controller, port or switch transparently and with no changes visible to the applications, other than perhaps resulting in increased latency.   Microsoft provides Device Specific Module (DSM) in Server 2008, 2012 and 2016, supports Asymmetric Logical Unit Access (ALUA), and can configure Multipath I/O (MPIO) environment with the storage device conforming to the SCSI Primary Commands (SPC) specification. DSM provides the load balancing policies, and load balance policies are generally dependent on the ALUA of the storage array attached to Win

Why is QStora a software-defined storage controller

Storage controller  is a device that manages the physical  disk drives  and presents them to the computer as  logical units .  It is also called "storage processor" or "array controller". Storage controller integrates the storage space in multiple storage devices and provides them as a single storage space to the client. When receiving a write data request from the client, the storage controller decides which of the multiple storage devices to allocate the data to, and stores the data in the selected one. When receiving a read request from the client, the storage controller finds the location where the data is stored, reads the data from the storage device and transmits it to the client. The storage controller performs these tasks in an efficient and stable manner. In addition to reading and writing data, the storage controller also implements various value-added functions, including dynamic allocation of volume capacity, snapshots, and so on. QStora is a software-d
