Why FlashRAID?
• How to do data protection for NVMe SSD?
– Hardware RAID has bottleneck
• How to management storage space for NVMe SSD?
– Traditional storage software (LVM, MD-RAID) has defects
Software Defined RAID is the Future

What’s FlashRAID?
• FlashRAID is a data protection and volume management system for NVMe SSD
– guarantee data protection
– Logic volume management

FlashRAID Data Reliability
• Reconstruction performance can be scalable due to RAID2.0 innovative architecture
– More SSDs, higher reconstruction performance
• Higher risk data can be recovered in higher priority due to smart reconstruction technology
– Priority reconstruction & data aware reconstruction
• End-to-end data protection and periodical data scrubbing can make data more reliable
– Data verification & Data scrubbing
• RAID0/1/5/6 data protection level are provided in FlashRAID

FlashRAID Benefits
Complexity
• Hyper-converge; reduce the complexity of maintenance and management
• Heterogeneous media automatic-management reduce the complexity of deployment
• High-performance at single host, reduce the system scale and complexity
Cost• Reduce cost of electricity, air-condition, datacenter scale• Runs on universal server, reduce system cost• Automation reduce cost of maintenance• Heterogeneous media reduce storage cost
Risk• Compatible with legacy storage and cloud storage, reduce
the upgrade risk• Runs on universal server, reduce procurement risk• Easy to upgrade at demand, reduce investment risk
