Announcing Oracle VM Server for SPARC 2.0

Honglin Su
Sr. Director of Product Management
Oracle VMToday, at Oracle OpenWorld, we are pleased to
announce Oracle VM Server for SPARC 2.0. Oracle VM Server for SPARC
allows you to create up to 128 virtual servers on one system to take
advantage of the massive thread scale offered by the SPARC T-Series
servers. The combination of Oracle Solaris and SPARC helps to increase
flexibility, isolate workload processing, and improve the potential for
maximum server utilization.

Oracle VM Server for SPARC 2.0 delivers:

Enhanced performance: A low-overhead
architecture provides scalable performance under increasing workloads.
 The performance is further accelerated by the PCIe direct I/O that
assigns individual PCI cards to guest domains, removing the restrictions
to only assign an entire PCI bus, while also providing native I/O
throughput. CPU whole core allocation and core affinity enable
organization to optimize the assignment of virtual CPUs to deliver
higher and more predictable performance for all types of application

resource management
: Dynamic memory reconfiguration allows memory to be added or
removed on an active domain. Customers now have the ability to
add/remove vCPU, virtual I/O, cryptographic units (aka MAU), and memory
on an active domain. These capabilities help organizations to better
align IT and business priorities.

Improved power management: CPU clock speed
adjustments, memory power management and power limit settings ensure
that energy consumption is optimized with utilization.
  • CPU clock speed
    adjustments - increase or decrease clock speed based on CPU utilization
    (per socket)
  • Memory power management - put under-utilized
    memory in a deeper idle mode
  • Power limit - set a
    power limit for the system and reduce the power state of manageable
    resource if the limit is reached.

Greater flexibility: Oracle Solaris has
been optimized for guest domain migration with Oracle VM Server for
SPARC, enabling more flexible migration of an active domain.

Higher availability: Improvements to
virtual disk multipathing enhance the availability of a virtualized
environment by helping to ensure that the virtual disk failover
capabilities can handle I/O domain, storage and storage-path failures.

Faster processing of
secure data
Oracle VM Server for SPARC takes advantage of SPARC T-Series systems'
integrated on-chip cryptographic accelerators that deliver wire speed
encryption capabilities, providing customers with critical data and
services protection and delivering better response times.
