In June 2010, Dell was operating some 1700 servers in various worldwide locations on SuSE Linux when it decided to migrate to Oracle Linux 5.5, leaving the hardware and application layers unchanged. Dell found sufficient capacity on some existing MegaGrid implementations to allow the applications and databases to be migrated to the grid and the SUSE Linux server powered down and decommissioned. Although Oracle does not support heterogeneous Oracle RAC clusters, Dell experienced no issues during the transition with nodes running SUSE Linux interoperating with nodes running Oracle Linux. Dell expects to complete the migration in June 2012.

How do you manage staff idiosyncrasies within the purview of a system administrator? You could allow access to all of your applications (from Oracle or other vendors) through Oracle Secure Global Desktop, which allows you to host the client side of the applications on dedicated Application Servers in the data center, which are tightly controlled and managed by IT. And Oracle Secure Global Desktop provides a simple, web-browser based way for users to access those applications remotely from Windows, Mac OS, Linux, and Solaris. Users don't have to be concerned about installing any client bits or complicated VPN software.

The Linux Foundation and Yeoman Technology Group conducted an invitation-only survey of 1893 enterprise Linux users. Among the findings are plans by 80% of respondents to implement Linux servers in the next 12 months; 72% plan to use Linux to support their "big data" operations; the number of respondents with reservations about technical issues declined from 40% in 2010 to 20.3%; 22% fewer cite perceptions by management as an impediment to Linux implementations, and 10% fewer cite no issues at all impeding the success of Linux; and some 66.6% of respondents consider Linux to be more secure than Windows.

Oracle's Sun Fire X4800 M2 server equipped with eight 2.4 GHz Intel Xeon Processor E7-8870 chips and 4TB RAM and 160 CPU threads obtained a result of 4,803,718 tpmC on the TPC-C benchmark with a price performance of $0.98/tpmC using the Oracle Linux OS with Unbreakable Enterprise Kernel Release 2 and Oracle Database 11g Release 2 with partitioning. This result is 2.5x times better performance than the next 8-processor result, an IBM System p 570 equipped with POWER6 processors, and 3.1x times better price/performance than the 8-processor 4.7GHz POWER6 IBM System p 570.

Oracle’s Sun Fire X4800 M2, running Oracle Database 11g Release 2, achieved an x86 record of 4,803,718 transactions per minute (tpmC) with a price/performance of $.98/tpmC. The X4800 equipped with eight Intel Xeon E7-8870 processors and 4 Terabytes (TB) of Samsung’s Green DDR3 memory was nearly 3x faster than IBM's eight-processor result for a p570 and nearly 60 percent faster than the best DB2 result on IBM’s x86 server. The Sun Fire X4800 M2 delivered nearly 3x better price per TPC-C transaction than a 64-processor HP Superdome server and over 2.65x faster than HP’s best Proliant DL580 G7 score.
