Glossary: Fault Tolerance

Glossary of Terms: Fault Tolerance

Definition: Fault tolerance is a level of protection in a computing environment used for mission-critical applications that require >99.999% availability and RTO and RPO of near zero. Fault tolerant systems require an investment in redundant hardware, software, networking and other systems. In these environments, two or more systems operate synchronously – performing compute functions simultaneously, so that in the event of a hardware, software, or network failure, application operation will continue without interruption or dropped transactions.

Changing A Drive Letter With Powershell

Changing A Drive Letter With Powershell

Here is a short but sweet post on how to change the drive letter of a partition. Despite using my best Google skills I couldn’t find an example that was doing it for me. I rolled up my sleeves and just figured it out on my own. I hope this helps someone out there.

Set-Partition -DiskNumber 4 -PartitionNumber 1 -NewDriveLetter X

As long as you know the DiskNumber and PartitionNumber this will immediately change the drive letter of the partition you specify.

You may also need to import the Storage module into Powershell before you can do this.

Import-Module -Name Storage

Let me know if this helped you

Disaster recovery software replicates or moves important data and applications to a location that is geographically separated from the production location so that,in the event of a sitewide or regional disaster, it can be restored.
