Dedupe or Not Dedupe: That is the Question!
Posted by Boris Yurchenko on February 22, 2018
5/5 (1)

When planning or improving an IT infrastructure, one of the most difficult challenges is defining the correct approach to developing it so that it requires as little changes at further scaling up as possible. Keeping this in mind is really important, as at some point almost all environments reach the state where the necessity of growth becomes vivid. While hyperconvergence is popular these days, managing large setups with less resources involved becomes quite easy.

Today I will deal with data deduplication analysis. Data deduplication is a technique that helps to avoid storing repeated identical data blocks. Basically, during the deduplication process, unique data blocks, or byte patterns, are identified and written to the storage array after being analyzed. While such analysis is a continuous process, other data blocks are processed and compared to the initially stored patterns. If a match is found, instead of storing a data block, the system stores a little reference to the original data block. In case of small environments, this is not crucial mostly, yet for those with dozens or hundreds of VMs, the same patterns can be met numerous times. Thus, due to the advanced algorithms used, data deduplication allows storing more information on the same physical storage volume compared to traditional data storage methods. This can be achieved in several ways, one of which is StarWind LSFS (Log Structured File System), which offers inline deduplication of data on LSFS-powered virtual storage devices.

Don’t break your fingers with hundreds of clicks – automate Windows iSCSI connections
Posted by Boris Yurchenko on February 20, 2018
No ratings yet.

If you have a single environment with only several iSCSI targets discovered from a couple of target portals, messing with automation may not be worth it. Yet, if you have multiple environments with a bunch of portals and targets that need to be discovered and connected, and all of them are more or less similar in terms of configuration, you might find your resort in automating the whole process.

I hope to post some other automation things here, so tune in and check the StarWind blog from time to time.

5/5 (2)

Azure Dev Test Labs

Official Microsoft description:

“Azure DevTest Lab is a service that helps developers and testers to quickly create environments in Azure while minimizing waste and controlling cost. You can test latest version of your application by quickly provisioning Windows and Linux environments using reusable templates and artifacts.”

In other words, Azure DevTest Labs is a great service that will help you to implement DevOps in your organization. Azure DevTest Labs will allows you to easily deploy Virtual Machines in order to test your workload in Azure. Setting up a development and test environment can take lots of time for your Ops Team. Let’s imagine that you have developers that want to be able to test their application using the latest version of SQL Server. You must:

  1. Deploy the VM
  2. Configure the VM
  3. Test the VM
  4. Configure RBAC
  5. Send the VM information with credentials to the Dev Team
  6. Check with the Dev Team if everything is ok
  7. If not, you must reconfigure the VM
  8. Check once again with the Dev Team

And so on…

Replacing a Veeam Agent for Windows host while preserving existing local or share backups
Posted by Didier Van Hoye on February 14, 2018

starting Veeam Agent for Microsoft Windows service - runing a full back up

Imagine you have a server with data source volumes that are backed up to local (or a share) target backup volumes with Veeam Agent for Windows (VAW). You might or might not backup the OS as well. That server is old, has issues or has crashed beyond repair and needs to be replaced. You don’t really care all that much about the server OS potentially but you do care about your data backup history! You don’t want to lose all those restore points. Basically, we try to answer how do you replace the backup server when it’s a local Veeam Agent for Windows 2.1 deployment.

How do you do this?

Migrate On-Premises VHD files to Azure
Posted by Nicolas Prigent on February 8, 2018

Azure Virtual Machines

You may need to move a couple of Azure Virtual Machines from on-premises to your Azure subscription. Thanks to Windows PowerShell, uploading a VM to Azure is really easy to do! You must check only one prerequisite before uploading your VM to Azure: you will need to check what type of virtual hard disk is being used by the virtual machine. Hyper-V can use either VHD or VHDX based virtual hard disks. However, only VHD disks can be uploaded to Azure. Azure does not support VHDX disks.

The most important part of any server infrastructure is the performance of the underlying storage which creates a direct dependency on the performance of the mission-critical applications. With all the available options for selecting the highest-performing underlying storage for your host taken into account, as well as the consideration of a lot of finger pointing once a storage array doesn’t perform according to plan, the responsibility involved makes the decision even more difficult than it seems.
