DS-AT1000S

 High-performance and high-reliability hardware platform: modularized and cableless design, SBB2.0 standard architecture, Xeon 64-bit multi-core CPU, 4 to 32GB cache, 1000M network interfaces x 4, key component redundancy
 Super large capacity and high-density design: 48 TB/U, up to 192TB storage space for single device, installation in 800 mm-deep cabinet
 Disk inspection and RAID optimization technologies
Disk inspection and repair: disk inspection and auto repair technology to improve disk usage
RAID optimization: various RAID modes (0, 1, 3, 5, 6, 10, 50), global or partial hot spare to protect data security;
VRAID (Video RAID) data protection: recording service will not be interrupted where there are multiple RAID bad disks.
Volume cloning: when RIAD fails, data can be restored through volume cloning technology only if disk is readable physically
 Security-dedicated direct write technology (Hybrid SAN):
High-performance stream data management structure: stream
media-based bottom layer management structure, which
protects file from being unreadable or lost in case of file system
damage; no file fragment will be generated by overwrite
Direct storage of mixed stream: direct storage of mixed video
stream and smart stream;
Transmission protocols: compatibility with RTSP, ONVIF, PSIA, protocols
 Enclosed Helium disk technology: introduce helium disk technology to security industry for the first time; fully isolate disks from dust, moisture, and impurity in air to increase reliability and stability
 Rich video applications:
Various recording modes, including alarm recording, timing recording, and manual recording;
Lock key video data to protect from being overwritten;
Auto Network Replenishment (ANR) and video loss detection/ alarm to ensure data integrity during network exception;
Hybrid SAN self-monitoring and recovery to avoid data loss or service interruption caused by configuration information exception
 Environmentally-friendly and energy-saving design:
Smart CPU frequency adjustment: adjust CPU frequency based on CPU usage to reduce system power consumption;
Smart fan speed adjustment: adjust fan speed finely to improve heat dissipation efficiency and reduce noise;
Smart disk dormancy: disks that have no r/w tasks will be in dormant state to reduce energy waste and prolong disk lifespan;
Physical space and power consumption conservation: ultrahigh-density design saves server room space and further reduces power consumption
 User-friendly maintenance interface:
Quick system configuration function;
User-friendly GUI for user to get device status information (key
component, storage resource, environment control information,
etc.) timely;
Rich alarm modes (LED indicator, message, and email) to improve device maintenance efficiency;
SADP protocol to auto search online storage in LAN;
Connection with mainstream network management systems via
SNMP; Centralized management of multiple devices
