06 Dec 2010 Oracle Processor Core Factor for SPARC Systems [23739]
SPARC64 VII+ Now a Core Multiplicator of 0.5

For many systems, the cost of the solution can be dominated by the Oracle license fee. A systems solution with CPUs that have a lower Core Processor Licensing Factor may end up with a lower overall cost than one with a smaller number cores that have a higher Oracle Licensing Factor (aka multiplier).

Oracle has set the multiplier for the newest SPARC chips - the SPARC T3 and the SPARC64 VII+ - very aggressively. The SPARC T3 has a multiplier of 0.25 - the same as the 1.0 GHz UltraSPARC T1 (as featured in the T1000 and T2000). The SPARC64 VII+ has a multiplier of 0.5, which is less than the 0.75 multiplier of the UltraSPARC IV, IV+ or the SPARC64 VI, VII which powered older systems like the V490, E6900 and E25k servers.

Note: the IBM POWER6 and POWER7 systems have a multiplier of 1.0. The latest AMD and Intel systems a have multiplier 0.5, twice that of the SPARC T3.

24 May 2010 Using Dynamic Resource Management in Oracle VM Server for SPARC [23139]
Defining Three Policies for Three Logical Domains

Orgad Kimchi has penned a five-page article on using the Oracle VM Server for SPARC (formerly called Sun Logical Domains or LDoms) version 1.3 Dynamic Resource Management (DRM) for allocating CPUs resources based on workload and pre-defined polices. This technical paper defines three policies for three logical domains, offering commands for managing a policy along with the specific add-policy commands for each logical domain and how to enable them.

24 May 2010 Oracle VM Server for SPARC [23156]
Reintroduction to the Former Sun Logical Domains

The once Sun Logical Domains is now the Oracle VM Server for SPARC. Leveraging the built-in SPARC hypervisor to subdivide supported platforms' resources (CPUs, memory, network, and storage) by creating partitions called logical (or virtual) domains, the Oracle VM Server allows for the creation of up to 128 virtual servers on one system to take advantage of the massive thread scale offered by the Sun SPARC Enterprise Systems with Chip Multithreading (CMT) technology. Honglin Su writing for Oracle's Virtualization Blog recapitulates the solution's features, architecture, and systems support.

26 Jan 2010 Sun BluePrints: "LDoms I/O Best Practices" [22736]
Configuring Highly Available Paths from Sun LDoms Guest Domains to Storage

The Sun BluePrints article "LDoms I/O Best Practices - Storage Availability with Logical Domains" by Peter A. Wilson discusses the approaches and trade-offs for configuring highly available paths from Sun Logical Domains (LDoms) guest domains to storage. Topics include I/O availability, multipath I/O with Solaris OS MPxIO, multipath I/O with virtual I/O failover, virtual I/O failover and network file storage, and multipath I/O to network file storage with virtual I/O failover.
