Software RAID-5 plus web server
- Linux/Apache vs. Windows 2000/IIS
Why software RAID?
- well-defined availability guarantees
- RAID-5 volume should tolerate a single disk failure
- reduced performance (degraded mode) after failure
- may automatically rebuild redundancy onto spare disk
- simple system
- easy to inject storage faults
Why web server?
- an application with measurable QoS metrics that depend on RAID availability and performance
