Objective: NAS (Network attached storage-networked attached storage) will connect storage devices to a group of computers through a standard network topology, such as Ethernet. NAS is a part-level storage method that The focus is on helping to address the need to rapidly increase

Different storage vendors have different iscsi configurations. Currently, three approaches are available: 1) directly add the target IP address on the host, and then discover the target. The UIT low-end server architecture storage has been discontinued) 2) some users need to add the iscsi initiator number on the target side, then discover on the initiator side, and then authorize the initiator on the target

Basic configuration of IBM storwize V5000 Storage Initial account passwordSuperuser/passw0rd Basic status of devices and systems First, add the configuration host. The premise is that the fiber optic cable has been connected and the fiber optic switch has been configured. Here we use fiber channel The system should be able to automatically identify the port. The host name can be set to the host model or

The IBM ds6800 storage can accommodate 16 Optical Fiber disks, for example, 16 4.8 GB disks with a capacity of TB. When the customer needs a larger space, they can connect 13 expansion cabinets to expand to 224 disks and get a capacity of TB. The Cascade method is: the first loop (gray loop) connects the ds6800 internal disk and the other six disk expansion cabinets, and the second loop (blue loop) conne

OpenStack is a cloud computing software developed by NASA and Rackspace, which is licensed by Apache License and is a free software and open source project. OpenStack is the IaaS (infrastructure, service) software that allows anyone to build and provide cloud computing services on their own. In addition, OpenStack is also used to create a "private cloud" within a firewall (private Cloud) that provides the resources shared by organizations or departments within the enterprise.

Block Storage SystemDistributed storage has excellent performance, can carry a lot of failures, it is easy to scale, so we use ceph to build a high-performance, high-reliability block storage system, and use it to support the public cloud and managed Cloud cloud host, the Cl

Internet. In the age of value Internet, data is the cornerstone of all values. The value of the Internet, which is represented by block chain technology, is leading us into the new data age. With the popularization of IoT, Edge computing and artificial intelligence, the new data age is coming. We know that most of the current mainstream cloud storage is based on data centralized processing methods. It is

Data such as chunks and transactions are ultimately stored in the LEVELDB database, and this article describes the storage formats for chunks and transactions in Leveldb. All code related to chunk storage and reading is encapsulated in Core/database_util.go, which allows you to figure out how chunks, transactions, and other data structures are stored in the database. Chunk
