2.1.1.1 Sizes and Specifications
The following sample virtual infrastructure sizing table describes three different service offerings—small, medium, and large. The service provider could also craft a custom offering which would go through a sizing exercise with the end customer to determine exact requirements.
In this example, there are three sizes of environment leveraging a single specification of host (2x 6 Core CPU @ 2.6 Ghz, 192 GB RAM and 1 TB of usable VMware vSAN™ local storage). The provider can offer different sizes of hosts to achieve economies of scale for the end customers.
Table 1. Hosted Infrastructure Service Examples
Size | CPU Cores and GHz | RAM GB | Storage GB |
Small (2x hosts) | 24 cores / 62 GHz | 384 GB | 2 TB |
Medium (4x hosts) | 48 cores / 124 GHZ | 768 GB | 4 TB |
Large (6x hosts) | 72 cores / 186 GHz | 1,152 GB | 6 TB |
Note Different hardware vendors offer different specifications. Make adjustments to suit your preferred hardware platform.
Note These specifications do not make adjustments for high availability (HA) reserved resources.
Where customers choose a custom option, you might need some sizing tools to determine the required amount of infrastructure.
