The Write Accelerator speeds up write-intensive Oracle databases
Texas Memory Systems, maker of the World's Fastest Storage®, today announced a new Write Accelerator specifically designed to increase Oracle database performance. It accelerates Oracle databases by allowing them to handle substantially greater transaction volumes and add more concurrent users. The Write Accelerator writes with 40 times less latency than the cache of a standard RAID array and is easily integrated into Oracle environments.
The Write Accelerator works on the simple premise that performance of write-intensive databases is limited by two factors: latency and throughput. The Write Accelerator, a special edition RamSan solid state disk solution, offers unparalleled latency and throughput and unbinds Oracle applications limited by slow writes.
Solutions provided to accelerate writes must meet three requirements: they must tightly integrate with the operating systems that run Oracle; must support Oracle and Oracle ASM; and must follow Oracle’s stripe and mirror everything (SAME) rule. The Write Accelerator supports Oracle in Windows, Linux, Solaris, HP-UX, OpenVMS, and AIX environments. The systems have been deployed with Oracle databases from Oracle 8i to Oracle 11g including support for Oracle RAC and Oracle ASM. The Write Accelerator consists of two separate, but bundled units, enabling complete support for SAME, and enabling even the most demanding enterprises in the world “five-nines” reliability for the solution.
The Write Accelerator can be directly attached to Oracle database servers or attached to storage networking components and does not require special skills or training to install and administer. Administrators simply move their redo logs, undo segments, or temporary tablespaces to the Write Accelerator. Neither the Oracle database nor the operating system has to be modified to support the Write Accelerator.
“Write activity in Oracle is mostly a factor of the performance of the redo logs, undo segments, and temporary tablespaces,” said Mike Ault, Oracle Guru at Texas Memory Systems and author of more than twenty books on Oracle performance and tuning-related topics. “By moving these files to the Write Accelerator, application performance is boosted as server resources are made available to support more transactions and more concurrent users. Plugging it in is easier, more effective, and less costly than adding additional RAID arrays or constantly tuning the database”.
Oracle database administrators can determine if their application suffers from poor write performance or other issues by analyzing their Oracle Statspack and Automated Workload Repository (AWR) reports using the free tool at StatspackAnalyzer.com. StatspackAnalyzer.com is an Oracle community forum that is co-sponsored by Texas Memory Systems and Burleson Consulting.
The Write Accelerator is immediately available. More information, including a detailed white paper and a five minute podcast by Mike Ault, is available online at http://www.ramsan.com/products/write-accelerator.htm.
