FORGOT YOUR DETAILS?

Electronic data storage needs are growing exponentially. As companies produce more information in the electronic format, management of storage space is a critical aspect to look at. Managing data storage while ensuring that performance, integrity, and scalability needs are met is quite challenging.

Calsoft’s File Systems Expertise

Storage vendors are developing advanced, next-gen file systems to cater to this growing need for data storage. Calsoft helps vendors test these file systems quickly and reduce time-to-market.

File System Testing Tools

Calsoft has worked extensively on various File System testing tools and has considerable expertise in file system development and testing. Calsoft has carried out stress testing and benchmarking for more than fifteen testing tools available in the market for various OS environments such as Linux and Windows. Calsoft has also identified the top five tools to test file systems -

  1. NFSx is the nfs version of fsx that is used by LTP to test the robustness of Linux File System
  2. Connectathon is the official suite used to test client/server interoperability
  3. Bonnie++ is a test suite which performs several hard drive/ filesystem tests
  4. XDD is a storage i/o performance characterization tool that runs on most Unix-like systems and Windows
  5. DBench is a filesystem benchmark that generates filesystem loads
