DS-A71024R/440 series storage system is a storage product with huge capacity and high-density design. A 4U chassis provides up to 440 TB capacity. Compared to general storage product, it reduces the total cost at up to 50%. iRAID technology realizes an intensive management for storage space and data, and protects the data security from substructure. Support periodic HDD replacement, which guarantees the product availability

Key Feature | Huge Capacity and High Density

• A 4U chassis provides up to 440 TB capacity
• High-density design reduces the installation space requirement and transportation cost

Low consumption

For 20 TB enterprise HDD, lower consumption for each terabyte at 50%

Security and Reliability

• iRAID technology and N + M redundant mechanism allow up to 2 error HDDs in a single RAID
• HDD encryption technology protects data security by only allowing Hikvision device to read the data in HDD

Maintenance-Free

• Rebuild fault HDD on-demand
• HDD periodic automatic replacement

Stream Data Management Structure of High Performance

Based on the bottom layer management structure of the stream media, it solves the problem that the damaged file system will lead to file unreadability or loss and ensures no file fragments will be produced during overwriting

Direct Storage of Mixed Stream

• Supports mixed storage of video stream and SMART stream
• Supports camera access through protocols including RTSP, ONVIF, etc.

iRAID

Erasure encoding and iRAID technologies ensure data integrity even when 2 HDDs in a single RAID are failed. If the number of error HDD exceeds redundant limit, other HDDs can still be read and written

Abundant Application

• Continuous recording, manual recording, and alarm recording

User-Friendly Operation and Maintenance

• Supports one-key configuration to improve system configuration efficiency
• Raises device maintenance efficiency via abundant alarm management methods, like alarm via indicators, and emails.
