Server Consolidation and Data Center Consolidation
By Rajesh Battala
Server consolidation is a key element of cutting IT costs. Novell products make it easy to assess your data center for consolidation and optimization. This not only helps your IT organization to reduce costs but also improves the efficiency of the usage of the resources, improves service levels and helps in better information organization.
The purpose of server consolidation is to use your computer servers more efficiently so you can reduce the total number of physical servers or server locations. Server sprawl is one of the main reasons you need to worry about server consolidation.
Server consolidation benefits include:
- Reduce Hardware Costs
- Reduce Maintenance Costs
- Reduce Support Costs
- Reduce Floor Space & Facility Costs.
Several factors typically drive an organization to look at server consolidation:
- As business becomes more competitive and recession affects the market, enterprises need to reduce their costs by using existing resources more effectively.
- Advancements in hardware from Intel and AMD have increased their capabilities with inexpensive multiprocessor and 64-bit machines.
- Virtualization support from some hardware vendors — Intel’s-VT capability and AMD-V Virtualization — makes virtualization more feasible.
There are lots of solutions available in the market for data center management. Novell’s Virtualization and Workload Management solutions are particularly well suited to help your organization with server and data center consolidation.
To Implement Server Consolidation:
- Inventory resources in the data center
- Monitor the resources’ usage and capabilities
- Analyze results
- Determine a server consolidation plan
- Execute the consolidation
- Manage the consolidated servers
Here is how administrators can execute the above steps using Novell products.
How PlateSpin Recon helps Server Consolidation:
PlateSpin Recon is not only a good monitoring product but also a great server consolidation reporter. It collects workload inventory and resource usage statistics.
PlateSpin Recon supports a high number of platforms.
PlateSpin Recon Platform Support
The following steps to implementing server consolidation are made a lot easier with PlateSpin Recon:
- Inventory the resources/workloads in the Data Center.
- Monitor the workloads for a period of time.
- Analyze the workloads’ usage from their monitoring data.
- Identify the candidates for consolidation.
- Generate a server consolidation plan.
To inventory the resources, Recon supports
- Individual machines
- Virtual Center
- IP Range
- Windows Domain
- CVS File
To inventory the machines we need to provide the credentials of the machines. PlateSpin Recon provides a good and easy way to manage the credentials of machines and maintain them securely.
Consider a case where you need to inventory the machines using IP Range Mechanism.
You just create some credential sets and assign them to particular platforms. Recon uses these specified credential sets to authenticate all machines in that IP range and inventory them. This will avoid a lot of the headaches of providing credentials to each machine.
If there is any failure in inventory just refer to the job logs which will help you understand why it is failing. Once the inventory of all the machines is successfully done, the next step is to Monitor the Machines.
To monitor the workloads of a machine, right-click and choose Start Monitoring. It gets the performance data of the server. To monitor a group of machines, select all the machines, right-click and choose Start Monitoring. At any time you can stop monitoring by right-clicking and choosing Stop Monitoring. Any time Monitoring fails, the associated log will be shown in the client which will provide necessary information for the problems.
Recon collects several detailed metrics of a workload depending on the inventory type. For example, tracking detailed metrics on storage usage over time, versus a simple point-in-time snapshot, PlateSpin Recon shows how and when physical servers consume local and remote storage resources iSCSI and FC SAN (at both the physical disk and logical volume level).
Data must be collected at least one hour before running Analysis Reports. To view the monitoring data or usage of the resources, Recon provides a chart where the monitoring data of the machines will be shown graphically.
PlateSpin Recon reporting will show the inventory and usage information in a detailed way.
Go to Report Explorer
Reports are organized according to category.
If you want to know all the inventory information, go to Inventory Node, select a category and right-click and generate a report. A report will be created and saved in the server.
Generate the reports after monitoring the workloads. The reports will give a good summary of how the resources are getting used in the Data Center.
There are three Consolidation Candidate reports generated that contain a listing of good consolidation candidates, poor consolidation candidates, and candidates requiring further investigation.
After monitoring the workloads for a certain time, Recon reports which tell which are good and bad candidates for server consolidation.
Go to Report Explorer under Consolidation and Consolidation Project Samples, select the appropriate template and generate the report.
Recon can deliver the reports via email, save as Network File, FTP, and will show in report explorer.
It also supports a wide range of output formats (pdf, png, jpg, excel, csv).
The report can be scheduled or it can be recurring to keep the administrator fully aware of data center status.
You should monitor the machines for at least 30 days to generate a good server consolidation plan. Consolidation scenarios use the performance data captured during monitoring to generate server consolidation scenarios.
The hardware, virtualization, and power and cooling information, as well as total cost of ownership and utilization thresholds, are values associated with PlateSpin Recon Server Templates.
Before starting on generating server consolidation reports, you should first determine the target hardware servers and virtualization technology.
Server Templates play a major role in server consolidation. By default there will be some commonly used server templates in Recon. Provisions are there to create or edit the server templates.
How to determine the consolidation and protection of workloads
- After monitoring the workloads for a period of time, go to Project Explorer and create a new project.
- Select the Project Type ( server consolidation or workload protection or both).
- Click Next and select all the machines for server consolidation.
- Click Next to specify the Data Range and the Business Days.
- Click Next to enter the Forecast Options.
- Click Next to specify the whether to Enable the Power and Cooling factors and their values.
- Now we are ready to create the project. Click Create to create the project.
Once the project is created it will be shown in the Project Explorer.
Under the project
Scenarios: user created scenarios will be shown
Existing Target Server: Contains the list of server class machines added to the project
Consolidate: workloads to be consolidate will be shown
Protect: workloads that can be protected will be shown
Some scenarios are:
- Determine the number of servers (selected from the server templates) required for server consolidation.
- User can specify the servers (from server templates or existing servers) and Recon will create a consolidate report accordingly.
In the first case, Recon will generate a report of how many specified servers are required to consolidate the workloads and how to group them also.
In the second case it will fit workloads well into the servers provided by the user.
The output of server consolidation reports are very optimal.
This is how PlateSpin Recon helps to generate the server consolidation reports to the administrator.
From this point PlateSpin Migrate takes control of implementing the scenarios generated using Recon.
As businesses grow rapidly there is a rapid increase in the computer systems in terms of size and management. These computer systems will have different configurations such as operating system, applications running on them, and hardware capabilities.
PlateSpin Recon helps by providing reports about how these computer machines are being used in the data center. Implementing the server consolidation plans generated by Recon, depending on the users’ needs, helps you manage and protect these workloads.
Protecting or moving the workloads is not a simple task, as it involves lots of tasks to be done very carefully and sometimes without disruption of the workloads. PlateSpin Migrate safely and easily moves or protects the workloads in the data center.
Migration of the workloads is either moving the workload on physical machine to a virtual machine or from a virtual machine to physical machines.
Protection of the workloads is to take the backups of the workloads into different images, so when a particular workload gets corrupted or damaged, the protected workloads will start running to provide the services.
