Server templates are used to define servers for use in consolidation scenarios. You create server templates, each with their own components and utilization thresholds. A common use for server templates is for scale-up or scale-out consolidation scenarios. The created server templates are used as target servers for consolidating workloads.
Click

Click .
The New Server Template dialog box is displayed.
On the General page, specify the following:

Processor Count |
Yes |
Total processor count. |
Processor Speed |
Yes |
Instructions per second the server can execute in MHz or GHz. The minimum processor speed you can use is 266 MHz. |
Memory |
Yes |
Memory size for server in MB or GB. |
Cores Per Processor |
Yes |
Number of cores per processor. |
CPU Model |
Yes |
Model of CPU:
NOTE:The CPU model for any processor in the Pentium series is shown as Pentium IV. This is based on the normalization speed that is calculated for a series of processors. |
Hyper-Threading |
No |
Specifies if hyper-threading is available. |
Normalized Speed |
Readonly |
A unitless measure of processor capacity. This provides more realistic comparisons across diverse processor architectures. |
Memory Size |
Yes |
The amount of memory to use. The minimum memory size you can use is 256 MB. |
Disk Space |
Yes |
Disk space in GB or TB that is required for the server. Select if you are connecting target servers to a SAN or NAS, where disk space is not a limiting factor. If you use , the minimum amount of disk space you can specify is 1 GB. |
Thresholds |
||
Processor |
No |
Processor utilization. By default, the utilization is set to 80%. |
Memory |
No |
Memory utilization. By default, the utilization is set to 90%. |
Disk Space |
No |
Maximum disk utilization threshold. By default, the utilization is set to 85%. |
Disk IO |
No |
Maximum disk I/O allowed. By default, the Max IO is set to 50 MB/s. |
Network IO |
No |
Maximum network IO. By default, the network IO is set to 10 MB/s. |
Thresholds specify the level of utilization the Consolidation Planning Module can assume for the server templates. This affects the outcome of consolidation scenarios; lower utilization thresholds result in more servers being required to host the workloads of a scenario.
For example: workloads requiring 180 GB of memory can be consolidated onto a server with 200 GB of memory if the utilization threshold is set at 90%. However, if the memory utilization threshold is set at 50%, only 100 GB of memory can be used, resulting in fewer workloads being consolidated.
Utilization thresholds are initially set to the defaults listed in the table above and can be customized for specific needs.
