One of the challenges when using any Operating System is answering the question 'Is my hardware supported?'. To track this down, you often have to scour Internet sites, hoping someone else has already asked the question, or do other, more horrible machinations – or ask someone knowledgeable. If you're running on an illumos-based system like SmartOS, OmniOS, or OpenIndiana, this just got a lot easier: Robert Mustacchi has created the list. Better yet, he has created a tool to automatically create the list.
The List
illumos now has a hardware compatibility list (HCL) available at
http://illumos.org/hcl.
This list contains all the PCI and PCI Express devices that should work. If your PCI device isn't listed there, don't fret, it may still work. This list is a first strike at the problem of hardware compatibility, so things like specific motherboards aren't listed there.
In his post on "How to Size Main Memory for ZFS Deduplication" Dominic Kay explains that, prior to using deduplication, one must first determine whether that operation is worthwhile by finding out the deduplication ratio and the memory requirements. Fortunately, ZFS itself provides a means to assist with this determination: the ZFS debugging tool, which will tell users whether deduplication will result in storage space savings. Establishing the memory available for deduplication can be accomplished by multiplying the number of allocated blocks by 320 bytes (the size of each in-core deduplication table).
The paper "MySQL Enterprise Backup and Symantec NetBackup" focuses on how Symantec NetBackup and MEB interact with each other. MySQL Enterprise Backup delivers online "Hot" database backup, whether full, incremental and partial backups, or Point-in-Time Recovery and backup compression. MySQL Enterprise Backup can interface with media management software (MMS) to execute backup and restore operations via System Backup to Tape (SBT) interface. SBT is the Oracle API implemented as shared library (libobk.so in Linux and orasbt.dll in Windows) to backup /restore data via 3rd party software vendors. Registration and log in are required to access the document.
On this episode of Meet the MySQL Experts Podcast, Mikael Ronstrom, senior MySQL Architect, discusses how the MySQL Thread Pool improves MySQL Scalability. Ronstrom summarizes the typical problems that commonly crop up when scalability is called for, one of them being MySQL Thread Pool itself, which was resolved in a later version. Ronstrom also notes the best use cases for MySQL Thread Pool, which are for sorting out active connections and managing long-running queries. Finally, he points out that, even with more than 64 active connections MySQL Thread Pool can produces results up to 20x better than MySQL Enterprise alone.
Users new to the command line feature of Linux can find a sympathetic ally in David Cardinal whose post on extremetech.com provides a helpful introduction to their structure and function. He begins with an explanation of the abbreviations commonly used in Linux, which can be fragmentary. One of the most helpful pieces of information Cardinal offers is his explanation of the wildcard as a shortcut in typing a Linux filename. This is a time- and keystroke-saver for sure. He also stresses the utility of the Linux control key sequences that, used improperly, have the potential to undo a user's intentions.
Companies that are building appliances with some Linux distro as the embedded OS can do better, argues Wim Coekaerts, than rely on community-based and/or community-maintained versions or even those commercial Linux distros that come with distribution and access restrictions. The alternative, Coekaerts suggests, is Oracle Enterprise Linux. Customers have complete access to the code and are able to use Oracle Enterprise Linux as they choose, without contract restrictions, nor even any license or activation key. This is one distro that can manage across all the use cases, says Coekaerts.
Using Oracle Validated Configurations is strongly urged in a post by Durgam Vahia, who describes the program as offering " ... pre-tested, validated architectures, with documented best practices for software, hardware, storage, and network components. This integrated approach helps improve the performance, scalability, and reliability of solutions, with faster, lower-cost implementations." The Oracle integrated stacks free the customer from the burden of testing a stack in their respective environments. They simply choose the Oracle Validated Configuration certified for their situation. Support is available for any and all components of each of the Oracle Validated Configurations.
Each year, Oracle releases its publication "Oracle for SAP Technology Update," as it has just done. Like its predecessors, the 2012 issue provides updates and information about Oracle products and services for SAP customers. The publication features content about running SAP on the Exa stack, including technical articles and customer cases. Users can download the 2012 issue as a PDF.
Oracle has created an interactive e-Book on the new SPARC T4 servers and SPARC SuperCluster. The e-Book, available as a PDF, includes such content as the SPARC SuperCluster T4-4 launch webcast; customer success stories; and 3D demos and detailed product information on all SPARC Servers.
As one of the comments on Joerg Moellenkamp's note concerning IOPS, storage capacity and bandwidth there is more to " ... storage than capacity, particularly IOPS and bandwidth." Moellenkamp pithily explains how the uneven progress among these three aspects of storage makes it essential to consider storage in as wide a context as possible in order not to wind up with massive storage on the other side of a bandwidth bottleneck.
