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:

Data Management Moves to the Fore. Part 4: Why Cognitive Data Management?
Posted by Jon Toigo on May 11, 2017
5/5 (1)

In previous installments of this blog, we have deconstructed the idea of cognitive data management (CDM) to identify its “moving parts” and to define what each part contributes to a holistic process for managing files and more structured content.

First and foremost, CDM requires a Policy Management Framework that identifies classes of data and specifies their hosting, protection, preservation and privacy requirements of each data class over its useful life.  This component reflects the nature of data, whose access requirements and protection priorities tend to change over time.

Design a ROBO infrastructure (Part 3): Infrastructure at remote office side

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.

Design a ROBO infrastructure (Part 2): Design areas and technologies
Posted by Andrea Mauro on February 24, 2017
4/5 (1)

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

The Virtualization Review Editor’s Choice is a selection of the most outstanding virtualization products of 2016. It is based on the opinions and overlooks by the trusted experts in the fields of virtualization and cloud computing. This is not the “best of the best rating”. No criteria were applied to make the list. This is just the collection of individual choices of writers, who deal with the industry daily, so they have pointed out virtualization solutions they found especially interesting and useful.

Is NVMe Really Revolutionary?
Posted by Jon Toigo on August 19, 2016
4/5 (1)

To hear advocates talk about NVMe – a de facto standard created by a group of vendors led by Intel to connect flash memory storage directly to a PCIe bus (that is, without using a SAS/SATA disk controller) – it is the most revolutionary thing that has ever happened in business computing.  While the technology provides a more efficient means to access flash memory, without passing I/O through the buffers, queues and locks associated with a SAS/SATA controller, it can be seen as the latest of a long line of bus extension technologies – and perhaps one that is currently in search of a problem to solve.

I am not against faster I/O processing, of course.  It would be great if the world finally acknowledged that storage has always been the red-headed stepchild of the Von Neumann machine.  Bus speeds and CPU processing speeds have always been capable of driving I/O faster than mechanical storage devices could handle.  That is why engineers used lots of memory – as caches ahead of disk storage or as buffers on disk electronics directly – to help mask or spoof the mismatch of speed.

How to Deploy and Manage Storage Spaces Direct Cluster using SCVMM 2016?

Windows Server 2016 – Storage Spaces Direct Hyper-converged [image credit: Microsoft]

Introduction

With the release of Windows Server 2016, Microsoft is introducing Storage Spaces Direct (S2D), which enables building highly available Software-Defined Storage systems with local attached storage. This storage can be leveraged by VMs running on the same cluster (in hyper-converged mode) or the storage can be presented as a File Share (in disaggregated mode). The hyper-converged deployment scenario has the Hyper-V (compute) and Storage Spaces Direct (storage) components on the same cluster. Virtual machine’s files are stored on local CSVs. Once Storage Spaces Direct is configured and the CSV volumes are available, configuring and provisioning Hyper-V is the same process and uses the same tools that you would use with any other Hyper-V deployment on a failover cluster.

Why moving from Windows Server 2012 R2 to 2016 for Hyper-V
Posted by Romain Serre on August 16, 2016
5/5 (7)

Windows Server 2016 will be released the next month said Microsoft the last month. Windows Server 2016 brings a lot of new features compared to the last Windows Server version for Hyper-V, networking and storage. In this topic I will try to convince you to move from prior Windows Server edition to Windows Server 2016 with eight reasons.

Windows 2016 Makes a 100% In Box High Performance VDI Solution a Realistic Option
Posted by Didier Van Hoye on June 27, 2016
5/5 (5)

1. Introduction

With Windows Server 2016 we have gained some very welcome capabilities to do cost effective VDI deployments using all in box technologies. The main areas of improvement are in storage, RemoteFX and with Discrete Device Assignment for hardware pass-through to the VM. Let’s take a look at what’s possible now and think out loud on what solutions are possible as well as their benefits and drawbacks.
