Demartek

Demartek focuses on industry analysis and lab validation testing of server, network, storage and security technologies, for the small and medium business (SMB) environment and the large enterprise. Demartek conducts research and lab testing resulting in white papers and product comparison reports.

  • editor's comments:- in November, 2010 - Demartek published a sponsored test report (pdf) which compares the performance of SSDs and HDDs in a simulated web server environment when managed by LSI's CacheCade software - which provides SSD ASAP functionality.

    Editor's commnents:- The report shows that throughput and access times were improved by at least 3x using a single SSD cache compared to the HDD only situation.

    However - it's disappointing that the sizing of the test was not best chosen to draw meaningful conclusions. Because the web content was only 25% larger than the SSD capacity! It would have been more helpful to design a simulated case in which there was at least a 10x or 100x size difference. Because if you can fit all the web content onto an SSD then you don't need the burden of the "cache" software at all - and might get better results by switching it off.

    There are case studies going back nearly 10 years which show that SSDs can provide big speedups in web servers. The exact speedup depends on how fast the SSD is. This test report doesn't answer the question - is LSI's CacheCade useful in a realistically scaled environment?
