Linux File System Limitations For High Performance Computing

Linux file systems have a number of limitations that make them a poor choice for large and high-performance computing environments. This article explains some of the pros and cons of Linux and old UNIX file systems:

I am frequently asked by potential customers with high I/O requirements if they can use Linux instead of AIX or Solaris.

No one ever asks me about high-performance I/O -- high IOPS (define) or high streaming I/O -- on Windows or NTFS because it isn't possible. Windows and the NTFS file system, which hasn't changed much since it was released almost 10 years ago, can't scale given its current structure. The NTFS file system layout, allocation methodology and structure do not allow it to efficiently support multi-terabyte file systems, much less file systems in the petabyte range, and that's no surprise since it's not Microsoft's target market.

Download of the day: IBM AIX 6 beta

Do you own IBM hardware such as IBM eServer p5, pseries or intelliStation POWER workstation? IBM is now offering the AIX 6 as a open beta software for testing. It appears that Linux has changed all the rules of the game ;)

From the IBM announcement web page:

1. Almost anyone who is interested will be able to download and install a pre-release version of AIX 6. By contrast, only a few clients would have the opportunity to test a new AIX release in a traditional beta.
2. Participants in the open beta will not receive traditional support from IBM. Instead, you access a Web forum to discuss questions and issues.
3. The only legal document required for participation in the open beta is a "click to accept" license agreement that clearly states all program conditions.
