Capacity planning by simulating UNIX servers
نویسنده
چکیده
This paper discusses the development and testing of simulation software for the measurement and modeling of UNIX performance data for data centers with mission-critical UNIX servers. The emphasis is on sizing CPU resources and assumes well configured Memory and Disk I/O subsystems. We begin by ensuring that our simulation package can be verified against the available theory on the subject, then compare it with a real life server and, finally, pose capacity planning questions by altering the simulation program’s input.

متن کاملVideo Server on an ATM Connected Cluster of Workstations
Video servers are important for applications which make use of digital video. The video servers should provide better functionality than most of today’s video servers offer, – e.g., support of flexible and instant user interactions, delivery of multiple video formats and support of virtual video documents. In this paper we discuss the requirements that video servers should fulfill and we descri...
متن کاملA Strategy for Adopting Server Virtualization in the Public Sector: NIPA Computer Center
Many public organizations have been adopting and operating various servers. These servers run on Windows, Unix, and Linux operating systems that generally use less than 10% of their capacity. For migrating a public organization to cloud computing, we must first virtualize the server environment. This article proposes a strategy for server virtualization that the National IT Industry Promotion A...
متن کاملUNIX Resource Managers: Capacity Planning and Resource Issues
The latest generation of UNIX includes facilities for automatically managing system resources such as processors, disks, and memory. Traditional UNIX time-share schedulers attempt to be fair to all users by employing a round-robin policy for allocating CPU time. Unfortunately, a loophole exists whereby the scheduler can be biased in favor of a greedy user running many short CPU-demand processes...
متن کاملMigrating from UNIX SMP Servers to Linux Clusters
The increasingly compelling price/performance and absolute performance advantage of Intel Architecture-based servers, coupled with the huge upswing in the popularity of Linux, is leading major data centers to migrate mission-critical applications from traditional large UNIX systems to Intel Architecture-based servers running Linux. Linux is very similar to UNIX – very little retraining of staff...
