Design a ROBO infrastructure. Part 4: HCI solutions

2-nodes hyperconverged solution

As written in the previous post, for ROBO scenario the most interesting HCI (Hyper-Converged Infrastructure) configuration is a two nodes configuration, considering that two nodes could be enough to run dozen VMs (or also more).

For this reason, not all hyperconverged solutions could be suitable for this case (for example Nutanix or Simplivity need at least 3 nodes). And is not simple scale down an enterprise solution to a small size, due to the architecture constraints.

Actually, there are some interesting products specific for HCI in ROBO scenario:

  • VMware Virtual SAN in a 2 nodes clusters
  • StarWind Virtual Storage Appliance
  • StorMagic SvSAN

Design a ROBO scenario must match finally the reality of the customers’ needs, its constraints but also the type of workload and the possible availability solutions of them.

Logical design of a ROBO scenario

When can found the different type of approaches:

  • No server(s) at
  • Few servers (that maybe can fail)
  • Some servers with “relaxed” availability requirements
  • Some servers with reasonable availability

Let’s analyze each of them.

In the previous post, we have explained and described business requirements and constraints in order to support design and implementation decisions suited for mission-critical applications, considering also how risk can affect design decisions.

Now we will match the following technology aspects to satisfy design requirements:

  • Availability
  • Manageability
  • Performance and scaling
  • Recoverability
  • Security
  • Risk and budget management

What is a ROBO scenario?

A Remote Office / Branch Office (ROBO) is an office located in a different site or a remote geographical area from another office (usually the headquarter or the main office). Several organizations have one (or more) main office, as well as remote offices in another city, country or continent.

Many organizations today have in each remote office some local IT infrastructure, usually for data locality, but also for service local services.
