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.

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...

Are all your IT resources being used efficiently?

As a Chief Information Officer (CIO) or corporate decision maker, you manage the corporate's IT operations and infrastructure. At present, the global economy is not very prosperous. You may not have much budget to buy new equipment, but there are growing storage requirements. You may have some servers for deploying applications, such as database, WEB application, etc., these servers have spare disk slots, and the utilization of CPU and memory may be not very high. So, why not make full use of these servers, fill up the disk slots, and let these servers be used for data storage at the same time? Especially for secondary storage like backups and archives, you don’t need to purchase a separate SAN storage device, you can use software-defined storage to save the TCO. Can all software-defined storage be mixed deployed with existing applications, regardless of the hardware environment and operating system? Of course not. Some software-defined stora...

DAS, NAS and SAN

There are 3 most prevalent storage types that are primarily deployed by enterprises, which are  DAS (Direct-Attached Storage), NAS (Network-Attached Storage) and SAN (Storage Area Networks). DAS DAS is a traditional mass storage, the storage devices are directly/physically attached to the computer through an internal cable, which does not use any network. This is still a most popular approach. It provides block-level access through Small Computer System Interface (SCSI), Serial Advanced Technology Attachment (SATA), or Serial Attached SCSI (SAS), etc. Advantages: Storage device is dedicated with high performace compared to NAS Lower cost,  inexpensive. Simple to configure and use Disadvantages: Inability to share data or unused resources with other servers efficiently. This is addressed by NAS ans SAN but at the risk of security and higher initial cost. Can not manage it by network No high availability Hard to expand storage capacity NAS NAS is mass st...
