Factors that affect storage performance
Storage performance is affected by many factors; however, some of them are really important. These are:
- VMFS partition alignment
- Spanned VMFS volumes
- SCSI reservation
To step through this recipe, you will need one or more running ESXi Servers, a vCenter Server, and a working installation of vSphere Client. No other prerequisites are required.
How to do it...
The first thing you have to counter is the VMFS partition alignment as follows:
- The alignment of your VMFS partitions can affect performance and it happens only if you create the datastore using CLI since the vSphere Client is not impacted by misalignment. Like other disk-based file systems, VMFS suffers a penalty when the partition is unaligned. ...
