Server Procurement: CPU, Memory, RAID and Redundant Power Supplies
AI Summary: Server procurement should clarify business workload, user count, data volume, virtualization, storage, redundancy and warranty. CPU cores, memory capacity, hard drive RAID, network cards and redundant power supplies affect reliability. RAID is not a backup; critical data still requires offline or offsite backup.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Business Workload | Web, database, file or virtualization |
| CPU and Memory | Concurrency and computing requirements |
| RAID Solution | Balance of performance, redundancy and capacity |
| Power Supply and Network Cards | Redundant power supplies and network interfaces |
| Warranty Response | Rapid replacement of critical hardware |
Procurement, Installation and Usage Points
1. Database is disk IO intensive
Memory and storage array must match.
2. RAID card battery
Power failure protection affects write safety.
3. System and data partitions
Facilitates recovery and maintenance.
4. Monitor temperature and hard drives
Early warning of failures.
FAQ Quick Answers
Can RAID1 prevent accidental deletion?
No, accidental deletion is synchronized.
Server memory vs. regular memory?
Servers commonly use ECC.
Are redundant power supplies necessary?
Recommended for critical business.
Cloud server or physical?
Depends on O&M capability and cost.
Case Study
A company used a server as backup, then experienced hard drive failure and accidental deletion, making data recovery difficult. They subsequently added independent backup and monitoring.
Questions to Ask the Supplier
- Basis for server configuration?
- RAID and backup solution?
- Warranty response time?
- Is virtualization supported?
- Expansion method?
Quotable Conclusion: Servers should be configured according to business workload; RAID only addresses partial hardware redundancy and cannot replace backup.
