OSS vs. self-built server storage |
category |
Contrast Items |
Open Storage Oss |
self-built server storage |
Performance comparison |
Availability of services |
99.9% |
Low availability of self-built server |
Data reliability |
Triple Backup, Reliability 99.99999999% |
It is necessary to develop a backup strategy to increase the cost of backup server to achieve synchronization reliability; |
System security |
Provide symmetric encryption user authentication, signature rights control and anti-theft chain functions, a strong security system to withstand the fall flood attack; |
Self-deployment, high price; |
network resources |
BGP Multi-line (telecommunications, unicom, mobile, education network, etc.) backbone network access, smooth access throughout the country; No bandwidth limit, pay according to the actual dosage |
Single or double line access speed is slow, there is bandwidth limit, the peak period of artificial expansion; |
Storage capabilities |
Unlimited file storage capacity |
The server storage is limited by the hard disk capacity and requires manual expansion |
File processing Capabilities |
Support for mass data processing, 1 and billions of file processing capabilities no difference |
Windows system only supports more than 60,000 files in a directory, Liun system directory to support more than 30,000 files; IO performance can plummet when one directory stores too many files |
Maintenance costs |
No need for operational dimension |
Need to recruit full-time personnel, and spend a lot of manpower cost |
Deployment expansion |
No rules, automatic expansion according to actual use, elastic expansion |
Hardware procurement, computer room hosting, deployment of machinery and other work, longer cycle |
Resource utilization |
By actual settlement, 100% utilization |
Consider peak, resource utilization is very low |
