Introduction
Analysis of core requirements
Data lifecycle management requires the use of archival-grade recordable Blu-ray discs for long-term storage, and the following must be tested:
| Parameters | PLS requirements | SLS requirements |
|---|---|---|
| Continuous read and write IOPS | ≥90% of the nominal value | Comply with DA/T74 |
| Service life | ≤5 years | ≥30 years (shielded castration case) |
Technological innovation dimension
Compared with traditional storage, this standard adds:
- Optical-magnetic random hybrid access mechanism
- Automatic diagnosis algorithm for batch optical disk durability
- Four-dimensional fault-tolerant verification framework (BE Sum/RSER/UE/LFS)
Analysis of implementation difficulties
Typical case: Construction of government cloud disaster recovery system
During the construction of a provincial archives, the following needs to be met:
- PLSTier uses all-flash array to achieve ≥500K IOPS
- Temperature control fluctuation in normal temperature storage area should be ≤±2℃
