Use Case Comparison of ORACLE 11gR2 and Sybase ASE 15.7 on Solid State Disks June 2, 2012

Database performance is ultimately constrained by the need to read and write data from a persistent storage. For almost the entire history of Oracle and Sybase, this persistent storage has been provided by the magnetic spinning hard disks (HDD). The relative performance of magnetic disk has been so poor compared to the rest of the hardware, that database performance tuning has focused primarily on minimizing the disk IO. Only now, with the advent of Solid State Disk (SSD) technology and in-memory databases, we are getting to the point of an increase in IO performance to match the improvements we have come to take for granted in CPU and memory access speeds.

Although replacing all the storage component of Oracle and Sybase with SSD is a rather expensive option for many shops, Both databases can benefit from an intelligent use of solid state disks. However, it is not always obvious how best to leverage limited quantities of SSD in order to get the best performance return from the investment.

A client of mine requested me recently to undertake “Use Case Comparison of ORACLE 11G and Sybase ASE 15 “on Solid State Disks. They wanted to improve their system response and both Oracle and Sybase databases were feeding their trading systems. I undertook this study separately for both Oracle 11gR2 and Sybase ASE 15.7 and the outcomes were very interesting. To simplify the matters we separated  read intensive and write intensive activities for both Oracle and Sybase. The results of the studies for read intensive activitiesfor Oracle have now been published in Oracle SELECT journal. SELECT Journal is a quarterly journal of peer-reviewed technical articles and news published by the Independent Oracle Users Group (IOUG). This article was published under title “Use Case Comparison of ORACLE 11g on Solid State Disks (Part One)” . The result of studies for write intensive activities for Oracle 11g will be published shortly

Likewise, the result of studies for read intensive activities for Sybase ASE 15 was published in International Sybase User Group (ISUG) journal in April 2012 edition titled “Use Case Comparison of ASE 15.7 on Solid State Disks [Part 1]“. The result of studies for write intensive activitiesfor Sybase ASE 15 have now been published in June 2012 edition of ISUG journal titled “Use Case Comparison of ASE 15.7 on Solid State Disks [Part 2]“.
