System Requirements for a Virtualized SRC Software
The system requirements for a virtualized SRC software are:
 | Note: We recommend you to allocate CPU cores, RAM, and hard disk space as same as that of C Series Controllers to attain better performance. |
Hard Disk Requirement
The qcow2 image grows in size up to 250 GB when used on a virtual machine, so you must have more than 250 GB of disk space in the host operating system if you use the qcow2 image.
If you are using an SRC iso image, we recommend you to have around 250 GB of disk space allocated to the virtualized SRC software to have enough space for system and component logs.
Memory Requirements
Table 1 lists the default heap size allocated for SRC components on a virtualized SRC software.
Table 1: Heap Allocation for SRC Components on a Virtualized SRC Software
SRC Component | Default Heap Size on Virtualized SRC Software | Heap Size Adjustable or Not |
|---|---|---|
SRC ACP | 64 MB | Yes |
SNMP agent | 160 MB | No |
Web application server | 616 MB | No |
CLI | 200 MB | No |
Diameter server | 600 MB | No |
External subscriber monitor | 160 MB | Yes |
3GPP Gateway | 200 MB | No |
IMS Services Gateway | 200 MB | No |
JPS | 400 MB | Yes |
License server | 1 GB or smaller than one-fourth of physical memory | No |
NIC | 128 MB | Yes |
SAE | 70% of free memory | Yes |
C-Web interface | 200 MB | No |
| Note: In a virtualized SRC software, the default heap size is set only for the Java components and not for the non-Java components such as redirect server. |
The memory requirements of the virtualized SRC software based on the default heap size allocation are:
- At least 2927 MB of memory is required for all Java components other than the SAE and license server.
- Subscriber management capacity of the virtualized SRC software depends on the heap size of the SAE. We recommend you to allocate enough heap size for SAE.
- 1 GB of memory is required for the license server.
CPU Requirements
You must allocate a minimum of one CPU core for a virtualized SRC software. You can allocate CPU cores same as that of C Series Controller to attain better performance. The CPU cores available in C Series Controllers are:
- C2000—4
- C3000—8
- C5000—24
