VMware ESX Server 2 NUMA Support
ثبت نشده
چکیده
ESX Server 2 provides memory access optimization for both Intel processors and AMD Opteron processors in server architectures that support NUMA (nonuniform memory access). This white paper provides background on NUMA technologies and a detailed description of the sophisticated NUMA optimizations available in ESX Server 2. The document contains the following sections: • Introduction • What is NUMA? • NUMA Challenges for Operating Systems • ESX Server NUMA Scheduling • VMware NUMA Optimization Algorithms • Manual NUMA Controls • IBM Enterprise X-Architecture Overview • AMD Opteron-Based Systems • Conclusions • Glossary This white paper is intended for partners, resellers, and advanced system administrators who wish to understand the unique advantages of implementing a VMware ESX Server solution on various NUMA-supported platforms such as those available from Hewlett-Packard, IBM, and Sun Microsystems.

VMware ESX Server is a thin software layer designed to multiplex hardware resources efficiently among virtual machines running unmodified commodity operating systems. In many computing environments, individual servers are underutilized, allowing them to be consolidated as virtual machines on a single physical server with little or no impact on performance. Similarly, many small servers can be c...
متن کاملVMware ESX Server: Providing LUN Security
VMware ESX Server provides strong security and performance isolation for virtual machine storage. Each virtual machine sees only the virtual disks that have been presented to its virtual SCSI adapters. Virtual machines cannot see the physical Fibre Channel HBAs on the ESX Server host on which they run. Nor, in typical use cases, do they see the LUNs on which their virtual disks reside. Emerging...
متن کاملAn Analysis of Disk Performance in VMware ESX Server Virtual Machines
The performance of applications running within VMs is a significant factor in their adoption. VMware ESX Server was designed for high performance, and its architecture is streamlined to provide high-speed I/O. In this paper, we focus on one component of ESX Server's I/O architecture, its storage subsystem. We look at the characteristics of a series of disk microbenchmarks on several different s...
