Solving Performance Problems with Solid State Drives
The continual growth in data volumes creates challenges in our SAS environments. More data to analyse and increasingly diverse uses of SAS Software causes more reading and writing of data, referred to as I/O (Input/Output). This is the biggest performance challenge we face.
Disks are commonly unable to read and write as quickly as CPU's can process, leading to I/O bottlenecks. This is indicated by:
- SAS sessions executing over a long period of time without obvious activity
- Extracting the appropriate timing information from the SAS log
- Monitoring the behaviour of your hardware at the operating system level
Amadeus improves performance by:
- Analysing the problems and recommending the appropriate Solid State Drive / Nand Flash technology
- Migrate your data between storage types
- Optimise your site configuration
We have observed average reductions of almost 60% in the elapsed time of SAS jobs when we used Fusion-io's devices in well configured SAS environments. Download the paper "Solving Performance Problems in the SAS Environment with Solid State Drives" for more information or contact us to find out more.
Consider the following graph which shows the I/O for three different data storage devices:
The I/O of a traditional mechanical disk clearly leads to longer running processes. The Fusion-io device has far higher data throughput resulting in shorter elapsed processing times and greater server utilisation.
