Download Available for Solaris 10 1/13 as Alternative
Oracle has releases a patchset of all the patches contained in Solaris 10 1/13 (Update 11) for both SPARC and x86 systems. The patchset includes an important post-S10U11 patch - 150125-01 (SPARC) / 149637-02 (x86) - and a fix for ZFS Bug 15809921. According to Gerry Haskins' post, this patchset can be applied to any existing Solaris 10 system to bring all pre-existing packages up to the same software level as Solaris 10 1/13.

Optimizing Storage Systems for DB Workloads [30346]
While Guaranteeing Best in Class Performance and Ease of Integration
Storage devices must embed a variety of features so that the optimal level of performance, manageability and operational agility can be achieved. Oracle's Exadata Engineered System does exactly that by embedding dedicated and highly optimized storage nodes that take in charge a part of the database workload in a way that a separate standalone storage device cannot. Philippe Deverchère reviews the requirements that must be met before one can deliver storage systems that can be used as primary storage for databases while guaranteeing best in class performance and ease of integration, noting that Sun ZFS Storage Appliance meets these requirements in large measure.

Is btrfs is better than ZFS? [30336]
Rudd-O.com Disputes the Notion
A post on Rudd-O.com challenges the view that btrfs is superior to ZFS, noting that the advantages of ZFS are practical consequences of the user-centered design decisions that obtained during the its development. Among the distinctions giving the edge to ZFS are that ZFS organizes file systems as a flexible tree while btrfs does not enable organizing subvolumes; ZFS file system operations can apply recursively but not in btrfs; ZFS auto-mounts file systems by default; ZFS tracks used space per file system; ZFS distinguishes snapshots from file systems, and so forth, with the evidence falling preponderantly on the side of ZFS.

Joerg Moellenkamp on Performance Analysis [30245]
In a Word (or Three): 'Never Assume Anything'
Readers with the time (and the interest) might wish to have a go at Joerg Moellenkamp's treatise on performance analysis, which parses the "methodology" of that task in a more semantic than methods-oriented fashion. He begins by taking exception to Brendan Gregg's post "The USE method addresses shortcomings in other commonly used methodologies," exception that bears more on philology than performance analysis. There is no disputing Moellenkamp's advice in the end, however: The more you know, the better you will be at performance analysis.
