OSS vs. self-built server storage

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
