Redundant fans, redundant power, and multi-redundant design ensure stability. The brand new design for disk carrier ensures good cooling, stability and safety for hard disks. Storage Extension Capacity Local extension, connecting to expansion storage cabinet by mini SAS interface. Extension storage supports redundant power and RAID. RAID 0/1/5/6/10/50/60 Offering a balance between storage performance, storage capacity, and data integrity, the EVS features fruitful RAID 0/1/5/6/10/50/60 for faster and safer recording. N+M Hot Standby The highly reliable redundancy N+M Hot Standby design provides a secure failover technique, ensuring immediate backup. In the event of a system failure, the slave instantly takes over the master to ensure no data is lost. ANR (Automatic Network Replenishment Technology) Video is recorded in SD card in IP cameras when the network breaks down, and after the network is recovered, the video will be transferred to EVS and then recorded on it.
