Project This work contributes towards: iPODS: Intelligent Performance Optimisation of Virtualised Data Storage Systems Project Objective: Strategies for Data Placement and Data Migration Project Partners: Sponsored by Ref: EP/F010192/1
Project Overview Disk Model Virtualised Tiered Storage System Model RAID Model
Initial Results: Zoned Disk model Measured and modelled cumulative distribution functions of data transfer time for 100MB requests. Measurements are taken from a single 7200rpm 500GB SATA Seagate disk (ST3500630NS).
Initial Results: RAID 0-1 Measured and modelled cumulative distribution functions of RAID 0-1 read (left) and write (right) requests. Measurements are taken from an Infortrend A16F-G2430 RAID system containing 4 Seagate ST3500630NS disks, with a stripe width of 128kB.
Initial Results: RAID 5 Measured and modelled cumulative distribution functions of RAID 5 read (left) and write (right) requests.
