- Blocks & Files: Now HP contributes HPC file system to open source - “HP has contributed its Tru64 UNIX Advanced File System (AdvFS) source code to the open source community, meaning Linux.” It’s been a long time since I’ve used AdvFS (the last time I used Tru64 was in 2003 or so), but it seems to me that this would maybe have been a lot more exciting if it had happened in 2000 or so. They do have a site up on SourceForge with source code already available for download, but I have to wonder how much interest this is going to attract with all the other file systems already out there.
- VMware VROOM!: Scaling real-life Web server workloads - “While the performance of each single-VCPU virtual machine is slightly lower than that of a one-CPU native machine (because of virtualization overhead), the cumulative performance of the multiple virtual machines well exceeds the performance of a large SMP native machine (because serialization penalties are reduced).” In other words, if you know that you have a scale out (instead of scale up) application, you can scale out by scaling up your virtualization server.
