ICT Infrastructure Environment Designer

This section of the Design tool lets you define your environment in terms of datacentres.  Add new DCs including the following infrastructure elements:

  • Physical Compute.  this includes elements such as database servers, appliances or specialists physical servers.
  • ESX Hosts.  Tell cloudstep about the ESX virtual hosts that are present in the datacentre and the ESX environment they are associated with.
  • Storage.  Indicate Storage equipment such as SANs and storage networking.
  • Networking.  Indicate core switching, firewall and routing equipment.

For each piece of equipment you need to provide:

  • The capital value of this equipment at its date of purchase.
  • The date of purchase for the equipment.
  • The refresh interval for the equipment that shows when you would re-purchase hardware.
  • The monthly running costs for managed services and other components that are allocated to the server (extended support for instance).

When populating the datacentre, the name of the datacentre will be used to build the names of the constituent infrastructure components.  These can be changed later.  The naming standard is as follows:

<DCNAME>-<COMPNENTNAME>-<NUMBER>

For example, the a datacentre called newdc2 has four ESX hosts in it and 2 SANs.  The result of creating these model Elements would be:

  • newdc2 (the datacentre)
  • newdc2-esx-0, newdc-esx-1, newdc-esx-2, newdc-esx-3 (the ESX Hosts)
  • newdc2-san-0, newdc-san-1 (Storage components)

Cloudstep will organise a view of this hardware that groups it by type (Compute, Storage, Networking) within specific datacentres.  

Start by clicking the button Add new or populate existing Datacentre to start adding a datacentre.  This will show the Add a new datacentre screen.  At any point you can click the Save button and a summary of your new infrastructure will be shown on the left hand side of the screen.  Initially it will contain only the datacentre but as you add more equipment of different types the summary will show this.  When you're ready you can click Build these in the model to create all the necessary model Elements.  You can also click Start Again if you ant to abandon your changes.  Until this point nothing has been added to the cloudstep model.  The names provider matter though.  If Elements already exist that match, cloudstep will update the values you've changed.

Adding a Datacentre

The first section is to tell cloudstep about the datacentre you plan to add to the model.  If you wish to add new equipment to an existing datacentre in the model then use the same name.  cloudstep will find the existing entry in the model and update it and add any new hardware into that datacentre.

Provide the following information:

  • Datacentre name.  This will be used as a prefix for any equipment that is added to this datacentre.  Make sure to keep it simple and "machine readable".  So rather than Coglin Street Datacentre use "cog-dc".
  • Start Date.  The date when the datacentre was commissioned.
  • Racks.  The number of racks in the datacentre.
  • Cost/Rack.  The monthly cost per rack which is multiplied by the number of racks to indicate the monthly fee.

You should click Save to create the datacentre before moving on.

Add Physical Compute Hardware

While modern datacentres are heavily virtualised there is often a need for physical hardware to deliver services that aren't suitable for virtualization.  These include hardware licensed servers for applications and databases and appliances.

Provide the following information:

  • Name.  Keep this simple as it will be combined with the name of the datacentre and a number, depending on the value provided for "How Many".
  • Capital Value.  The initial purchase pricing of the infrastructure
  • Refresh Interval.  The number of years between purchases or refreshes of this equipment.
  • How Many?  The number of hosts of this type to add to the datacentre.
  • Monthly Running Costs.  The cost per month to operate this equipment.  This is considered a Managed Services fee.
  • What do they do? - The purpose of these servers, one of:
    • Database Servers
    • General Purpose
    • Appliances
  • Operaing System.  One of:
    • Windows
    • SUSE
    • SLES
    • Linux
    • NA
  • CPU
  • Memory
  • Storage

Add ESX Hosts

Most modern datacentres are heavily virtualized.  ESX environments generally have several Virtual Hosts that provide the compute, memory and storage capacity required to deliver the fleet of virtual machines.  These hosts contribute greatly to the overall running cost of the environment.  You can add several ESX Hosts at once with the same specification and capital value or you can add them separately.  You should provide the following:

  • Start Date.  The purchase or commissioning date of the hardware.
  • Capital Value.  The initial capital purchase price of the hardware.
  • Monthly Running cost.  Any service fees associated with the ESX hosts.  These will be considered Managed Services.
  • Refresh Interval.  The frequency with which these hosts will be replaced.
  • How Many?  The number of hosts you want to add at this purchase price and date.
  • ESX Environment.  Your environment may have several vSphere environments, indicate which one these are attached to.

Add Storage Equipment

Most modern datacentres have centralised Storage Area Networks and storage arrays.  You can add one or more SANs to the datacentre.  Provide the following information:

  • Start Date.  The date when the equipment was purchased.
  • Capital Value.  The initial capital value of the equipment.
  • Monthly Running Cost.  The monthly cost of managed services, licensing or extended support.  This is considered Managed Services.
  • Refresh Interval.  The frequency with which this equipment is refreshed.
  • Storage.  The capacity of the storage network.

Add Networking Equipment

Most on-premises or 3rd party datacentres have networking equipment in them.  Its not important to model every individual piece of equipment, you can bundle them together as distribution switching for instance.  For key pieces of infrastructure such as routers and firewalls it is important to add them separately.  Provide the following information:

  • Start Date.  The date when the equipment was purchased.
  • Capital Value.  The initial capital value of the equipment.
  • Monthly Running Cost.  The monthly cost of managed services, licensing or extended support.  This is considered Managed Services.
  • Refresh Interval.  The frequency with which this equipment is refreshed.

There are a few different types of networking equipment you can add:

  • Distribution Switching
  • Core Switching
  • Routing
  • Firewalls
