Product Description Data Storage System
A data storage system (DSS) is a fault-tolerant complex of hardware and software designed to store and manage large amounts of data at high data transfer rates. Data transfer speed is measured in IOPS — the number of read and write operations per second.
Depending on the amount of your data, the tasks you are solving and privacy settings, it can be stored:
- в Storage logical unit (LUN);
- on dedicated storage in one of pools;
- on cartridges tape storage.
Storage can be connected to one or more dedicated servers:
-
Storage LUNs can only be connected to dedicated servers arbitrary configuration with a 2 × 10 GE NIC + 10 Gbps SAN connection to the storage LUN. The server must be in the same pool as the storage LUN;
-
dedicated storage can be connected to dedicated servers with a 2 × 10 GE NIC + 10 Gbps SAN connection to the storage LUN.
Tasks to be solved
LUN storage is used for deploying your own virtualization system, working with hot backups, databases and media files.
Dedicated storage is used to handle large amounts of data.
Tape storage is used to meet deadlines for long-term data storage and to store data without network access.
LUN STORAGE
Storage LUN is a software isolated, preconfigured part of a dedicated storage. Logical units of one storage can be allocated to different clients, and common network interfaces are used for connection.
We highlight the LUN on the Huawei OceanStor Dorado 5 000 V6 storage system from the all flash lineup. Its performance indicators are 8,000/ 8,000 IOPS per TB of data.
The performance of each LUN depends on its capacity. The larger it is, the higher the performance. Change the volume of the LUN at any time.
Dedicated storage
Dedicated storage is a hardware-isolated storage system with no preconfiguration. Dedicated network interfaces are used to connect to it.
The parameters of the storage system and its manufacturer are selected individually.
Tape storage
Tape storage is a standalone storage system that uses magnetic tapes in cartridges to record data. Data is written to 18 TB LTO-9 tape cartridges. The cartridges can be transferred to an individual storage cell upon request.
You can rent a single cartridge or a dedicated tape library in its entirety. If you only rent cartridges, Selectel retains the tape library administration service. To write data to a cartridge, you will need storage to which you will save backups, such as cloud storage, a virtual machine, or an FTP server. Data is written to the cartridge in a pre-agreed scenario, such as daily, every other day, or once a week.
We use tape storage systems from HPE, DELL and IBM. The parameters of the tape storage system are selected individually.
Areas of responsibility
Selectel ensures the uptime and availability of the storage system.
For LUN storage, we are responsible for administration and pre-configuration. Read more in the document Terms of use of individual services: LUN storage.
Selectel is not responsible for the configuration and administration of dedicated storage.If you need help with administration and configuration of dedicated storage, order service administration services.
