Oracle VM Server for SPARC 3.4 Released!

We are pleased to announce the release of Oracle VM Server for SPARC 3.4, which has been delivered as part of Oracle Solaris 11.3 SRU 8.7. Together, they provide new features for virtualization, performance, security, scalability, and system management.

Oracle VM Server for SPARC 3.4 introduces several new capabilities, including the following:

  • The virtual HBA (vHBA) method of doing I/O introduced with Oracle VM Server for SPARC 3.3 has been enhanced to better support I/O resiliency, multi-pathing, monitoring and large configurations.
  • Verified boot can be used to enhance guest domain security by verifying signed boot blocks and kernel modules.
  • Trusted guest domains can be permitted to assign alternate MAC addresses and VLAN IDs, especially for domains running OpenStack.
  • Inter-vnet-link Logical Domain Channels (LDCs) are automatically enabled unless more than a tunable number of virtual network devices are on a virtual switch, in order to conserve use of LDCs.
  • The number of LDCs has been increased to a maximum of 4096, for further scalability.
  • Device properties for InfiniBand SR-IOV devices can now be modified without domain reboot.

Announcing Oracle VM Server for SPARC 3.1 Release

We are pleased to announce the availability of Oracle VM Server for SPARC 3.1. The new release delivers significant virtual networking performance improvements, more flexibility to configure I/O virtualization, and further enhancements for cross-CPU secure live migration to help customers take advantage of the massive thread scale offered by SPARC servers and the Oracle Solaris operating system.

See the key features and benefits delivered in Oracle VM Server for SPARC 3.1:

  • Virtual network performance improvements: Significantly improve the virtual networking performance up to 5 times faster. For example, guest to external network approaches wire-speed at ~9Gb/s; while for the guest to guest within the same host, it's measured up to 16Gb/s. For more details, read the blog.


  • Dynamic Single-Root I/O Virtualization (SR-IOV): Bringing configuration flexibility to I/O virtualization with native I/O throughput. For more details, read the blog

  • Cross-CPU secure live migration enhancements: Perform secure live migration across different generations of SPARC servers, including the new SPARC T5 and SPARC M5. For more details, read the blog.
  • Extends the Direct I/O and SR-IOV features to non-Primary root domains. For more details, read the blog
  • Adds InfiniBand device support to the SR-IOV feature in addition to the Ethernet devices.
  • Adds the Fault Management Architecture (FMA) blacklisting feature. When FMA detects faulty CPU or memory resources, Oracle VM Server for SPARC places them on a blacklist. A faulty resource that is on the blacklist cannot be reassigned to any domains until FMA marks it as being repaired.
  • Adds a recovery mode feature that automatically recovers domain configurations that cannot be booted because of faulty or missing resources.
  • Adds the ldmpower command to show per-domain, power-consumption information.
  • Adds support for VNICs on virtual networks.
Read the blog to learn the in-depth details of the new release and how to upgrade to the latest release. Please review the What's New section and the documentation about specific details of required and minimum software and supported platforms. Visit the download page for instructions to download the required software.

Announcing Oracle VM Server for SPARC 2.2 Release

We are excited to announce Oracle VM Server for SPARC 2.2, the latest release of Oracle’s enterprise-class server virtualization solution. The new release delivers significant enhancements that improve workload agility and performance, maximize the availability of business-critical applications, and increase flexibility in provisioning and deployment. Oracle VM Server for SPARC takes advantage of the massive thread scale offered by SPARC T-Series servers and the Oracle Solaris operating system.

See the key features and benefits delivered in Oracle VM Server for SPARC 2.2:

  • Secure live migration is now available across different generations of SPARC T-Series servers for flexibility of workload deployment and migration. Customers continue to benefit from their existing investment as they add SPARC T4 servers into the environment for increased capacity with minimal downtime or disruption to their operation. Secure live migrations are as simple as point and click using Oracle Enterprise Manager Ops Center’s console. Read more about Cross-CPU Secure Live Migration here and watch a video demo.
  • Single-Root I/O Virtualization (SR-IOV) delivers superior I/O throughput to guest domains that have SR-IOV on Oracle's SPARC T4 and SPARC T3 platforms. SR-IOV enables the efficient sharing of PCIe network devices among I/O domains so application workloads can achieve native I/O performance. Read more about SR-IOV feature and SR-IOV Virtual Function (VF).

  • Integrated optimization with SPARC T-Series servers, especially for SPARC T4 and SPARC SuperCluster T4-4, provides administrators with fine-grained control of server resources and the ability to tailor CPU performance across business-critical enterprise workloads for better throughput. Read more about whole core allocation enhancements here.

Please review the Oracle VM Server for SPARC 2.2 Documentation for specific details of required and minimum software and supported platforms. Visit the download page for instructions to download the required software.

Optimize Workload Performance on SPARC T4 Systems with Oracle VM Server for SPARC

Early this week Oracle launched SPARC T4 Servers and SPARC SuperCluster T4-4. With Oracle VM Server for SPARC, the built-in server virtualization solution on SPARC T-Series systems, you can use dynamic CPU threading controls to optimize workload performance on SPARC T4 systems.

These threading controls enable you to specify the number of hardware threads to be activated per core. CPU performance can be optimized for CPU-bound workloads by tuning CPU cores to maximize the number of instructions per cycle (IPC). Or, CPU performance can be optimized for maximum throughput by tuning CPU cores to use a maximum number of CPU threads. Existing applications can take advantage of the SPARC dynamic threading performance benefits without having to be rewritten or recompiled.

To learn how to use CPU threading controls to optimize CPU performance on SPARC T4 platforms,  read the white paper:
