At the EAKC2012
Conference last week in Edinburg, Robert Milkowski, Unix engineer at Morgan Stanley, presented on deploying OpenAFS on Solaris 11
. It makes a great proofpoint on how ZFS and DTrace gives a definite advantage to Solaris over Linux to run AFS distributed file system services, the "cloud file system" as Robert calls it in his blog
. Robert used ZFS to achieve a 2-3x compression ratio on data and greatly lower the TCA
of the storage subsystem, and DTrace to root-cause scalability bottlenecks and improve performance. As future ideas, Robert is looking at leveraging more Solaris features like Zones, ZFS Dedup, SSD for ZFS, etc.
