Exadata Database Machine

Exadata Database MachineAn Appliance and moreDATA Processing- HistoryCPU processor performance doubles every 12 to 18 monthsMemory increased almost at the same rateDisk Capacity is also increasing at escalating rate

In 1990 1370 MB drive speed 4.4MB/s 5m timeIn 2013 1TB drive speed 100MB/s 2hrs 30mins time

Disk Speed relying on mechanical part , much slow, more disk spindles are needed , more connection to storage over faster interconnect to the memory needed. storage latency.Closer data is to the CPU, better the performance
