Dynamic N+M mode: 1+1, 4+1, 8+2, 12+3, 16+4, data is still usable after M storage nodes fail

File System

File System

Dahua EFS distributed file system

Data Type

Video, image and document

File-level Access

Global namespace, fIle can be accessed by 3rd party application directly

Load Balancing

Load balancing based on capacity and performance of each node

Data Recovery

Valid data recovery instead of entire disk recovery

Scalability

Storage Expansion

Scale-out technology, online expansion, with less than 60 seconds for expansion of a single node

Quota Management

Data quota management based on users, user groups and directories, allocation of capacity on demand

Performance Index

Read/write Performance

Sequence read/write: 4 GB/s

80% read, 20% write: 3.5GB/s

20% read, 80% write: 3.5GB/s

50% read, 50% write: 4GB/s

Data Recovery Speed

2 TB/h

Stream Processing Performance

Number of video channel: 2000/node

Storage bandwidth: 700Mbps/node

Fowarding bandwidth: 700Mbps/node

System Management

Initialization

One-click system initialization

Condition Monitoring

Real time health status monitoring including processor usage, memory usage, disk capacity, etc.

Alert By Email

Alarm notification of system exception by email

Disk replacement

batch replacement of bad disks, avoiding the work for immediate replacement once a single disk fails
