I'm currently looking at the following machines one is a tower the other is rack server.
| Dell Precision T7500 WorkStation |
| Intel Xeon Quad Core 2.66Ghz |
| Intel X5550 Processor 8MB L3 Smart Cache |
| DVD Burner Drive |
| 24Gig DDR3 RAM (Support up to 192Gb RAM) 6 X 4GB |
| 1Tb 7.2K SATA 3.5" Hard Drive |
| nVidia Quadro FX580 Video Card |
| DVD Drive |
| 2 X Gigabit Network 10/100/1000 |
| Full Size 4U Tower machine |
| Dell PowerEdge 2950 III Server |
| 2 X Intel Xeon Quad Core 3.0Ghz E5450 |
| 32GB RAM DDR2 PC5300 |
| 2 X 1Tb 7.2K SATA Hard Drives |
| DVD ROM Drive |
| 2 X Gigabit Network 10/100/1000 |
| 2 X Redundant Power Supplies |
| 2U Rackmount Size |
My primary use for this machine is to use Cisco VIRL a simulation program below are some guidlines. My secondary use will be used to a home server for backup and storage.
The key factor for determining memory is to determine the number of virtual devices (nodes) that you want to simulate. This should be based on a cumulative number:
- Number of concurrently active simulations and the sizing of the topologies
- Types of nodes that users can activate, for example, Cisco IOS or IOS XRv Software, and so forth
As a guide, following are the general memory requirements for supported virtual images:
- Virtual Cisco IOS Software requires 512 MB of memory to run each node.
- Cisco CSR 1000V requires 3 GB of memory to run each.
- Cisco IOS XRv Software requires 3 GB of memory to run each node.
- Cisco NX-IOS Software requires appox 4 GM of memory to run each node.
