Activity of the ZFS Adaptive Replacement Cache
Using kstat and DTrace
Using the statistics generated by kstat and the tracings derived from DTrace, Brendan Gregg examines ZFS Adaptive Replacement Cache (ARC) activity in detail. In addition to calculating hit and miss rates, Gregg discusses other statistics including prefetch and metadata ratios, then writes about using tracing to observe information from the ARC – including who is using the ARC and why, ARC buffer sizes, the age of the ARC buffers, lock contention timings and eviction details. He points out that more can be traced as needed: ZFS with DTrace provides great performance and observability.

Automated Diagnosis for Sun SPARC Servers Offered by My Oracle Support
Users Must Upload Oracle Explorer to Access this Feature

Oracle Sun SPARC T-Series servers now feature automated diagnosis as part of the My Oracle Support services. Users are strongly urged to upload an Oracle Explorer when asked in the Service Request (SR) creation process in My Oracle Support (MOS), which will allow the SR to be handled by Automated Diagnosis and speed up the service process significantly. By not uploading an Explorer during SR creation or shortly afterwards Service Requests will follow the normal process. Automated Diagnosis will not be used on P1 Service requests or Accounts that have special handling instructions.

Nexenta Trashes Win8 Storage Spaces
'Just Not Enterprise Class'
Microsoft's Storage Spaces may well be fine for storing family photos and other personal memorabilia but as an enterprise storage tool? Not so much, contends Nexenta CEO Evan Powell in The Register article by Chris Mellor, noting the absence of such features as double and triple parity RAID, the ability to snapshot and replicate data, and the cryptographic-strength 256 bit checksums of ZFS-based solutions found in NexentaStor, which provide end-to-end data integrity. In addition, Powell points out the 16 Terabyte (16 TB) limit in the capacity of Storage Spaces. "It just isn't enterprise class," Powell asserts.

    Anatomizing an Oracle Solaris Binary File
    The Tools and Techniques You Will Need
    When application object files and executable binary files become unhandily large, it is helpful to be able to see inside such files. In order to do that it is necessary to know what tools are called for in such an inquiry and which parts can be reduced in size. In her oracle.com/technetwork post Miriam Blatt discusses these issues, reviewing the contents of binaries and the tools that are available to read, extract and delete sections. She concludes with a discussion of the effect on binary file size of compiler flags and how to reduce the size of the executable.

    Analyzing Interrupt Activity with DTrace
    A Useful Tool in Assessing the Effects of 'Pinning'

    Interrupts are events delivered to CPUs, usually by external devices and can cause performance and observability problems for applications. Tim Cook's post explains the use of DTrace in identifying the source of interrupts and solving the performance problems caused when an interrupt "steals" a CPU from an application thread, halting its process while the interrupt is serviced. Cook calls this pinning (the interrupt will pin an application thread if the interrupt was delivered to a CPU on which an application was executing at the time). Cook cites several DTrace scripts to use in assessing the effects of pinning.

    How to Use Oracle Solaris 11 Network Virtualization and Resource Management
    Restricting Application Network Traffidc
    Users can now monitor, control, guarantee, and reconfigure network infrastructure to provide applications with the required data connections using Oracle Solaris 11 Network Virtualization and Resource Management. Duncan Hardie's post on Oracle tech network showing how to apply bandwidth limits to both data links and user-defined flows to manage network traffic. Hardie also shows how data link bandwidth limits all traffic through that data link, whereas bandwidth limits applied to flows can be based on network packet characteristics. These technologies allow users to create a flexible and controlled environment to meet all their network resource management needs.
