For information about the features introduced in all versions of the Oracle VM Server for SPARC (Logical Domains) software, see What's New in Oracle VM Server for SPARC Software.
The major changes for the Oracle VM Server for SPARC 3.3 software are as follows. Note that each feature is available on all supported platforms except UltraSPARC T2, UltraSPARC T2 Plus, and SPARC T3 unless otherwise stated. For the list of supported platforms, see Supported Platforms in Oracle VM Server for SPARC 3.3 Installation Guide .
Support the virtual SCSI host bus adapter (vHBA) feature, which enables you to virtualize any type of SCSI device (such as disk, tape, CD, or DVD). The virtualized SCSI device is accessible from a guest domain.
The vHBA feature is compatible with other I/O interfaces such as MPxIO multipathing, which enables a virtual LUN to have the same behavior as a physical LUN. vHBA also enables you to easily configure virtual SANs, which can contain an unbounded number of SCSI devices. See Introduction to Virtual SCSI Host Bus Adapters in Oracle VM Server for SPARC 3.3 Administration Guide and the ldm(1M) man page.
This feature is supported on UltraSPARC T2, UltraSPARC T2 Plus, and SPARC T3 systems as well.
Enable recovery mode by default. See Recovering Domains After Detecting Faulty or Missing Resources in Oracle VM Server for SPARC 3.3 Administration Guide .
This feature is not supported on SPARC T4 systems.
Add Oracle VM Templates commands to create, deploy, and configure Oracle VM templates for SPARC systems. See Chapter 18, Using Oracle VM Server for SPARC Templates, in Oracle VM Server for SPARC 3.3 Administration Guide .
This feature is supported on UltraSPARC T2, UltraSPARC T2 Plus, and SPARC T3 systems as well.
Support whole-core dynamic resource management (DRM). See Using Dynamic Resource Management in Oracle VM Server for SPARC 3.3 Administration Guide .
Add support for CPU socket constraints. See Fujitsu M10/SPARC M10 Systems System Operation and Administration Guide.
This feature is supported only on Fujitsu M10 servers.
Enhance the live migration feature to enable memory block splitting. Memory block splitting eliminates the requirement to have sufficient free contiguous memory regions on the target machine for each memory block that is assigned to the guest domain. The migration can split up memory blocks in the guest domain to fit into available free regions on the target machine.
This feature requires that you run the Oracle Solaris 11.3 OS on the guest domain being migrated.
This feature is supported on UltraSPARC T2, UltraSPARC T2 Plus, and SPARC T3 systems as well.
Enable autoreplacement of faulty CPUs with bound processes and faulty CPUs in single-core domains. See Fujitsu M10/SPARC M10 Systems System Operation and Administration Guide.
This feature is supported only on Fujitsu M10 servers.
Dynamically update the net-dev property value by using the ldm set-vsw command.
Expand cross-CPU migration to include the SPARC T7 series servers and SPARC M7 series servers. See Domain Migration Requirements for CPUs in Oracle VM Server for SPARC 3.3 Administration Guide and Cross-CPU Restrictions for Migration in Oracle VM Server for SPARC 3.3 Administration Guide .
Provide support for Ethernet over USB to enable the ldmd daemon to communicate with the SP and provide support for an ldmd connection check. See How to Verify the ILOM Interconnect Configuration in Oracle VM Server for SPARC 3.3 Administration Guide .
This feature is supported only on SPARC T7 series servers and SPARC M7 series servers.
