Support from the bottom of AMD Virtualization Technology-AMD, server, network-IT industry
In April, the official Barcelona into the market, Dell , HP, Sun and other important Cooperation Partners, have launched a virtualization application for Server . Dell in particular, is introduced PowerEdgeR805 and R905 servers. PowerEdgeR905 is refreshed in the use of 60 virtual machines in VMmark performance testing records, there was some industry concern. HP and Sun also launched A new focus on propaganda MD Quad-core Barcelona virtualization performance advantages, then Quad-Core AMD Opteron processor virtualization performance advantages of what expression? AMD's product manager Mr. Liang Hongwei to reporters a detailed and thorough analysis.
Current customer challenges, a lot with virtualization related. So Barcelona's advantage in the virtualization to solve the many problems facing the industry, such as increased performance, investment protection, energy saving, green and so on.
Virtualization in enterprise computing can be said is a common topic. X86 processor-based virtualization technology is the area in recent years, the server is very hot a topic. The current trend of virtualization technology are gradually migrated from the mainframe to other mainstream industry standard X86 inside. These servers are not early virtual environment for custom things, when added in the future of virtualization, you may face more problems in performance.
Virtualization technology allows a single physical machine into a lot of logic machines. Exclusively on a server before the operating system, is now turned into a virtual machine application form, re work in virtual environments, virtualization technology, therefore reducing the number of physical servers, improve server utilization can be largely on reducing power consumption to save energy, the enterprise data center features a very high value.
AMD Opteron processor designed from the ground up for virtual overtaken on further optimization to further improve performance, reduce CPU Energy consumption. For example, the dynamic core technology with independent, low-power DDR2, Memory , Dual Dynamic Power Management. These new dynamic power adjustment feature allows many servers to automatically adjust intelligent, CPU load according to the system, running on the Regulation of its own frequency and voltage, the lower power consumption than their lower.
The same time, AMD Opteron processors for virtualization performance also made the corresponding optimal design, which in addition to its own architecture, AMD has also introduced the RVI (Rapid Virtualization Indexing), Marked-style performance of TLB and a list of DEV unique technology to solve virtualization performance and safety issues.
First single from a performance point of view, in the dual system, AMD Opteron dual-core Opteron than 60% of the upgrade, the system will have similar four dual-core to quad-core from the larger rate improved. In floating point and memory-sensitive applications which have significant performance improvements. RVI, namely, AMD Rapid Virtualization Indexing is the four-core Opteron processor introduced virtualization optimization technology, the improvement of the performance is very obvious. The Microsoft platform, in the semi-virtual environment can achieve 14% performance increase, after the RVI enabled, you can upgrade 50%. If the Linux environment, which, in half inside the virtual environment, performance enhancing a times, combined with RVI will increase more than 200%. RVI open and close later on virtualization performance increase is obvious.
Second virtualization technology called TaggedTLB (with marked TLB). To enhance the virtual machine and physical machine data transfer and translation between the conversion, Barcelona used with marked TLB (Translation Look-aside Buffer, address translation reserve buffer, which is CPU in a table used to store recently used from virtual to physical memory translation of records, 'tag' which means that data is a virtual machine), makes multiple virtual machines running simultaneously, the switch in the memory address that TLB can make Hypervisor and virtual machine-one correspondence between relations, to improve virtual machine performance. AMD TLB will provide users with excellent marking performance.
Third technology, is AMD's advanced Direct Connect Architecture to enhance virtualization for server performance play an important role. As the virtual machine takes a lot of memory, AMD's Direct Connect Architecture can be very large memory management.
But still address the complexities of access, which will lead to the virtual machine memory management more complex, virtual machine memory page is not a real physical memory, so virtual machines to its actual physical address mapping will need to know that this is in the past called shadow page tables, a third party Software Management, maintenance, and for the operating system is transparent. If you spend a lot of CPU time to maintain the virtual machine to access the page table, will affect the performance of the entire virtual machine. In AMD's virtualization technology, you can directly know the address of the mapping, the virtual machine at run time do not need the help of a translator, and their direct implementation by means of hardware, hardware for address translation, and I quickly access the physical memory. Before the virtual machine and memory when talking to the middle of a translation, that translation is the hypervisor. Such a benefit will quickly improve the performance of virtualization.
Finally, the physical machines in the past an application for an exclusive, now turned into a virtual machine to be shared by many, it faces many new problems, such as memory to the virtual machine at the same time for many to share. AMD introduced the DEV, DEV protection can be created in the memory domain, by refusing to unauthorized memory access request, make equipment without authorization, shall not access the memory page. Realized in hardware, embedded security, to improve virtual machine efficiency. Hardware-level security to provide better efficiency.
Equipment list, and Direct Connect Architecture, fast indexing of several new technologies to achieve greater memory capacity support, including lower memory latency, etc., while in the energy saving achieved outstanding virtualization performance. To help enterprise customers achieve better results.
As the leader in virtualization technology, AMD is also using its virtualization technology. AMD Austin headquarters in the data center, full adoption of virtualization technology. In the past 100 server virtualization technology to the integrated application, the current number of physical servers only 7 units. Headquarters in another 33 units from the compressed to 2 sets, integrated view of integration ratio to 17:1. Integrated industry applications, virtualization, probably in the compression ratio between 1:10 and 1:20. Save a lot of money
