Intended Audience This white paper is written for users who need to use OVPA data with Capacity Advisor. 1 Introduction HP Integrity Essentials Capacity Advisor is a tool in the HP Virtual Server Environment Management (VSEMgr) suite designed for doing capacity planning by simulating placement of application workloads to help IT administrators improve server utilization. Capacity Advisor captures server utilization data and manages what-if configuration scenarios to perform ongoing capacity planning.
2.1 Importing OVPA data from HP-SIM nodes This section presents the process for importing OVPA data when the target system is listed in HP-SIM but not in VSEMgr. This process requires that: • • The system is a HP-SIM node and is not listed in VSEMgr A ssh connection is enabled for the given system. ssh is required to execute the capovpaextract command on the CMS.
4. As root user on the managed node, cd to the directory where you copied the files in Step 1 and execute the following commands: ./extracttool –f –b FIRST –e LAST cp .capextractdir/sysConfig.dat /var/opt/mx/data/HOSTNAME.sysConfig.dat cp .capextractdir/sysGlobal.dat /var/opt/mx/data/HOSTNAME.sysGlobal.dat cp .capextractdir/sysDisk.dat /var/opt/mx/data/HOSTNAME.sysDisk.dat cp .capextractdir/sysNet.dat /var/opt/mx/data/HOSTNAME.sysNet.dat cp .capextractdir/missingData /var/opt/mx/data/HOSTNAME.miss rm –rf .
Figure 1 Example: Importing OVPA Data from Systems without ssh 1. 2. 3. 4. 5. 6. 7. Copy files from the CMS to the managed node. Access target host. Set permissions. Extract OVPA data. Copy files and run capovpaextract. Copy workload .csv file back to CMS. Import workload .csv file into Capacity Advisor. 4 Using Imported Data in Scenarios This section describes how to use workload data from non-VSE systems in a Capacity Advisor scenario. To import non-VSE workload data, do the following: 1. 2. 3.
IMPORTANT: When moving imported workloads, it is crucial to enter a platform CPU multiplier. Capacity Advisor uses a multiplier computed from the clock speed of the system to scale a workload’s demand profile when it is moved from one system to another. Such an estimate gives numbers that are usually accurate within 10% when moving workloads within the PA family of processors or within the Integrity family of systems.
