Oracle 吃下 SUN 後，除了 x86 Virtualization 的產品 -- Oracle VM Server for x86 以外，也有針對 SPARC 推出虛擬化解決方案。(昇陽時代稱為 Sun Logical Domains)
日前釋出的版本為 Oracle VM Server for SPARC 2.1，支援 Live Migration。以下為主要功能 :
- Live migration: Enables users to migrate an active domain to another host machine while maintaining application services to users. Live migrations are as simple as point and click using Oracle Enterprise Manager Ops Center’s console.
- Secure, encrypted migration included: On-chip cryptographic accelerators deliver secure, wire speed encryption capabilities for live migration – without any additional hardware investments.
- Dynamic Resource Management (DRM) between domains: Ensures that domains running the most important workloads get priority for CPU access over domains with less critical workloads.
- Increased maximum number of virtual networks per domain: Permits a dramatic increase in external access to domains.
- Lower-overhead, higher scalability networking for Oracle Solaris 11 Express: Allows virtual network devices to use shared memory to exchange network packets, enabling improved performance and scalability.
- Support for Virtual Device Service Validation: Immediately validates the name and path for a specified network device or virtual disk, greatly reducing the risk of incorrectly configured I/O.
- Integrated Dynamic Reconfiguration (DR) of Cryptographic units and virtual CPUs: Cryptographic units and CPUs are dynamically reconfigured together to simplify operations and ensure consistent performance.
- Enhanced Management Information Base (MIB): Enables the SNMP MIB to use the latest Logical Domains Manager XML interface, permitting third party management software to access the new features and resource properties.
- P2V tool enhancements: Bring more flexibility to quickly convert an existing SPARC server running Oracle Solaris 8, 9 or 10 into a virtualized Oracle Solaris image to run on SPARC T-series servers.
