Make a disaster recovery plan with Veeam Backup & Replication 9.5

Veeam Backup and Replication is a backup and replication product. The backup part ensures your workloads are protected against bad manipulation, ransomware or disaster. It enables to restore the data in case of loss. The replication part ensures that your workloads can quickly start again in another datacenter in case of sinister in the first one. Products such as Microsoft Hyper-V or VMware vSphere can also handle this task. In this topic, I will show you how to leverage Veeam Backup and Replication to make a disaster recovery plan. The same steps can be applied to Hyper-V or VMware but in this topic, I will take VMware as example.

Disaster Recovery and why hypervisor HA may not be best

A lot of the time I see and speak to people asking about DR solutions when what they really want is HA with a few backups so I wanted to use a blog article to go through some of the technical terms used in conjunction with DR. When people say “I want DR”, I’ll ask them about the sort of disasters they are looking to protect against and most of the time the response is “I want to keep working if my hypervisor crashes”.

Eliminating Blue Screen or Errors during failover

The reason for writing this post was a recent case from one of our customers, who ran into an issue when their SAN switch failed. The problem was that their VMs were generating an enormous amount of errors that were caused by the switching of active paths at the time of failover.

vSphere 6.5: HA & DRS improvements. Part I

A number of improvements that have been introduced in vSphere HA and DRS in the last several years are impressive. vSphere 6.5 continues this tradition by bringing new features into HA Admission Control, by adding flexibility with HA Orchestrated Restart and by enabling DRS to make more intelligent balancing. I will be trying a new format today. First, I will be explaining the challenges you might have had in previous vSphere releases and then I will show you how the new vSphere 6.5 HA & DRS features address those challenges.

Storage HA on the Cheap: Fixing Synology DiskStation flaky Performance with StarWind Free. Part 3 (Failover Duration)

We are continuing our set of articles dedicated to Synology’s DS916+ mid-range NAS units. Remember we don’t dispute the fact that Synology is capable of delivering a great set of NAS features. Instead of this, we are conducting a number of tests on a pair of DS916+ units to define if they can be utilized as a general-use primary production storage. In Part 1 we have tested the performance of DS916+ in different configurations and determined how to significantly increase the performance of a “dual” DS916+ setup by replacing the native Synology DSM HA Cluster with StarWind Virtual SAN Free.

vCenter Server High Availability Review – Part 1

High Availability for vCenter Server has never been as important as today when there are so many products dependant on vCenter, e.g. VMware NSX, vSAN, Horizon View, etc. VMware tried different approaches to bring HA to the vCenter.

How to Configure Storage Replication using Windows Server 2016? – Part 2

1

Warning: This article is written with information related to Windows Server 2016 Technical Preview 4.

In part one of this multi part blog on How to Configure Storage Replication in Windows Server 2016, we covered an introduction into Storage Replica which is a new feature introduced in Windows Server 2016, and we covered step by step the implementation of Windows Volume Replication (Server-to-server). In this follow up post, we are going to cover the implementation of volume replication with stretch cluster. This type of cluster features uses Asymmetric storage, two sites, two sets of shared storage and uses volume replication to ensure that data is available to all nodes in the cluster.

Hyper-V: Free “Shared Nothing” SMB3 Failover File Server

A part of a series, the research is dedicated to the capability of free Microsoft Hyper-V Server R2 to assume a file server role and cluster the resulting file server. Our last experiment on this matter showed that it’s possible to create SMB3 File Server on the free Microsoft Hyper-V Server R2 and now we’re about to go further and cluster it. The post shows a detailed instruction on the process and also the resulting setup. It appears to be fully working and usable, so the process may be called a success after all. Though it is absolutely real to do so, it is a violation of Microsoft’s license agreement, so StarWind urges everyone to refrain from repeating the experiment.

Storage Spaces Direct: 4-node “Shared Nothing” Scale-Out File Server

This is a research dedicated to practical implementation of Microsoft Storage Spaces Direct. It is a part of a series of posts about S2D and features a detailed comprehensive instruction on building a fault-tolerant 4-node setup. Storage Spaces Direct is the next step of Storage Spaces, meaning it is an extension of the current SDS for Windows Server. Storage Spaces Direct utilizes SMB3 for all intra-node interaction, including the latest SMB Direct and SMB Multichannel. The testing of S2D is hot right now, so StarWind is doing its part as well. This setup is meant to withstand node failures and the post reveals how exactly it performs in this respect.
