AMD Difference

The performance of a VDI solution can be enhanced with AMD hardware. Large numbers of VMs mean large memory requirements. The AMD Opteron processor, with its increased memory addressability and high memory bandwidth, can support a large number of concurrent, memory-intensive VMs.

Some key AMD advantages for Virtual Desktop Infrastructure environments include:

* More VMs per server
Direct Connect Architecture helps eliminate the bottlenecks because everything is directly connected to the CPU—the processors, integrated memory controller, and I/O connect directly to the CPU and communicate at CPU speeds.

Integrated Memory Controller is designed to improve performance on memory-intensive virtualization environments through high bandwidth, low latency, and scalable access to memory.

HyperTransport™ technology optimizes the movement of data and the sharing of resources among VMs for greater system scalability.

* Better Performance in Virtualized Environments
Rapid Virtualization Indexing, an enhancement to AMD-V technology, is designed to increase the performance of the most demanding virtualized applications through hardware-assisted memory management.

Address space IDs (ASIDs) decrease context switching overheads and increase the performance of VMs.

* Increased Responsiveness in Virtualized Environments
Tagged Translation Look-aside Buffer (TLB) addresses switching times between VMs by mapping to the VMs’ individual memory spaces.

* More Efficient Security
The Device Exclusion Vector (DEV) controls access to VM memory based on permission, isolating VMs for secure operation.

* Smooth Upgrades
The AMD common-core strategy, same-socket infrastructure, and stable, long-term road map makes it possible to perform seamless upgrades of processor technology, helping IT administrators minimize the cost of transitions and maximize past investments in hardware, software, and personnel.
