The impact of storage design in VDI
As we go further down the road of moving workloads to virtual infrastructure, it is imperative to understand the moving parts that make up the virtual infrastructure. One of the main bottlenecks for virtual environments is shared storage I/O. Ruben Spruijt recently posted an article on BrianMadden.com explaining impact of storage design for VDI environments; although, the information shared in the article is useful for any virtual environment. The article explorers
- Client I/O
- Storage I/O
- SCSI versus ATA
- RAID levels
- Disk alignment
- Prefetching and Defragging
To quote Ruben, “…there is a hidden danger to VDI. There’s a killer named ‘IOPS’”.
