Appendix D: Server Performance Analyzing and Scaling
These counters are referenced in Step 7: “Design the Farm,” in which the form factor and size of the terminal servers and the TS Web Access server are determined. They are also referenced in Step 9: “Size and Place the Terminal Services Role Services for the Farm , ” where the form factor and sizing for each of the Terminal Services role services is determined. Proper design and sizing of the terminal server and the Terminal Services role services is critical to the effective operation of the environment, particularly since the servers will host a somewhat unusual workload: multiple copies of applications that were likely originally designed to run on client workstations. The variety of components in this workload means that there is no “one size fits all” answer for terminal server sizing, so careful measurements and testing must be performed in order to arrive at a design that is capable of meeting end users’ expectations.Analyzing Storage Performance - Counter of the Week - Site Home - TechNet Blogs
Introduction The purpose of this article is to provide prescriptive guidance on how to troubleshoot logical and physical disk response times in regards to Windows performance analysis. Average disk seconds/read and average disk seconds/write (response times): Are the users having to wait for application responses? Are we exceeding established thresholds for disk drive performance degradation (generally > 15 ms)? Throughput: Are we saturating any of the pipes, such as mainboard bus, SCSI connection, SAN connection, or other link between servers and storage. Are we reaching the throughput limit of the disk subsystem?
Analyzing storage subsystem performance is an art, not a science. Each rule has an exception; each system designer or administrator has a different combination of hardware configurations and software workloads to consider. This paper examines the performance of storage subsystems used by computers running the Microsoft Windows 2000, Windows XP, or Windows Server 2003 family of operating systems.
