DAS is a method of data storage in which a storage device is attached to a single host directly, rather than over a network. This can be a standalone drive, an external drive, or a DAS server with its own power supply, cooling, and controllers.
DAS usage scenarios:
- In home environments where simplicity, low cost and reliable storage are important. Personal PCs and laptops can be easily connected to DAS - it turns out a convenient archive of personal files and data. But keep your home DAS in a safe place so as not to repeat my success: I kept a home DAS (USB connection) with all the photos of my favorite cats, connected it to my laptop and accidentally dropped it on the floor while it was turned on. Press F to respect, as they say. Make backups, friends. As I do after this story.
- In offices, especially in small companies. DAS provides high performance, control and increases storage security. With DAS, you can process large amounts of data - work with them without copying to a workstation or PC.
- Professionals in content creation. For example, videographers and sound engineers use DAS to store and edit large multimedia files. Fast data access, high performance, and redundancy make DAS an excellent option for work.
- DAS can be adapted to back up data from other devices. A good option for backups (one of the links) according to the 3-2-1 rule.
Advantages of DAS:
- High performance: Data access speed is limited only by the DAS device and host interfaces. Plus, there are no network connection delays.
- Simplicity: A novice sysadmin or user with instructions can handle deploying a DAS. But if your DAS is a flash drive for a computer, then even children 2+ can handle it
- Reliability: There is no risk of network failures, switches, etc., as the data is stored locally. Therefore, there are fewer points of failure and higher reliability.
- Security: Full control over data as it never leaves the host device.
DAS limitations:
- Access: Data is only available to the host to which the DAS device is connected. A disadvantage when multiple employees in the office need access, and a serious disadvantage when remote access to data is required (e.g. in branches). You will have to convert the computer + DAS connection to a NAS server.
- Scalability: The maximum amount of data in a DAS device is limited by the disk basket and supported drives. Once you run out of bays, you run out of scaling. Simple DASs have one to a few drives; advanced DASs have high storage density with a large number of drives.
- Physical vulnerability: To avoid losing data from a DAS device, backup measures and redundancy of critical nodes are required.
- Management and Monitoring: Incomparable to network storage and storage networks in flexibility and speed of service. Requires more manual work.
- Virtualization: DAS in virtualized environments limits the management, sharing, and movement of virtual machines between hosts.
DAS connection options: speed table
Modern versions of USB have good bandwidth.
- USB 3.0 (3.2 Gen 1) - up to 5 Gbit/s.
- USB 3.1 (3.2 Gen 2) - up to 10 Gbit/s.
- USB 3.2 (3.2 Gen 3) - up to 20 Gbit/s.
Fibre Channel is widely used in data centers due to its high bandwidth.
- Fibre Channel 16G (16 Gigabit) - up to 16 Gbit/s.
- Fibre Channel 32G (32 Gigabit) - up to 32 Gbit/s.
- Fibre Channel 128G (128 Gigabit) - up to 128 Gbit/s.
Serial Attached SCSI (SAS) is a reliable and productive interface, widely used in servers and SRDs. Suitable for connecting DAS devices.
- SAS-2 - 6.0 Gbit/s.
- SAS-3 - 12.0 Gbit/s.
- SAS-4 - 22.5 Gbps, called "24G".
