Basic application scenario

2200v3 block

1. A maintenance terminal is connected to the storage system through a management network port or the management network port of SVP (18000 series storage systems). You can manage and maintain the storage system on the maintenance terminal running the DeviceManager program developed by Huawei.

2. The storage system provides storage space for application servers

3. Storage systems can be connected to application servers running different operating systems including Windows, Linux, and UNIX over an Internet Small Computer Systems Interface (iSCSI), Fibre Channel (FC), or InfiniBand (IB) network.

According to data transmission protocols, an application server functions as the initiator for data transmission, and a storage system serves as the target for the information. The initiator sends data read and write requests to the target. The target receives, processes, and responds to the requests.

4. Application servers run client programs. The storage system can connect to application servers running different operating systems including Windows, Linux (SUSE, and Red Hat), UNIX (Solaris, AIX, and HP-UX), and VMware ESXi.

Storage system

2200 v3 block

1. The storage system automatically identifies all disks.

2. Disk domains are composed of the same or different types of disks. Services of different disk domains are isolated from each other.

3. Storage pools are created in disk domains and comprised of RAID groups formed by disks of different performance. For OceanStor 2000, 5000, 6000, and 18000 series storage systems, a storage pool can be divided into three storage tiers based on storage media: high-performance tier, performance tier, and capacity tier.

4. A LUN obtains storage space from the storage pool. LUNs are the minimum logical storage units that can be identified by application servers. A LUN group may contain one or multiple LUNs.

5. After mappings between host groups and LUN groups are established, related application servers can access LUNs.

6. After initiators are added to hosts, one-to-one logical mappings between hosts and application servers are established. Then application servers can use storage space provided by the storage system. A host group may contain one or multiple hosts.

7. The application server identifies LUNs as logical disks. Then it can access the detected logical disks in the same way it would access local disks.
