Currently I’m reading Mastering VMware vSphere 4. So how is this book? I want to follow KISS principle here which means Keep it small and simple.
And my recommendation is It will make you Master in vSphere.
From the storage chapter, I got inspired and and I’m putting across virtual machine disk size consideration sheet using Google docs
|Virtual Machine Disk Size consideration|
|1||VMDK Size (MB)||40960||editable|
|2||Reserved Memory (MB)||512||editable|
|3||Configured memory (MB)||1024||editable|
|3||Snap shot allowance||15%||may not change|
|Actual Disk Size (MB)||47616||Formula field do not change|
- Put the disk size in MB
- If you choose to reserved some memory put across
- And finally snapshot consideration I used 15% of total disk size.
- Actual Disk Size has formula=[DiskSize +(Configured memory – Reserved memory) + (Snap shot allowance X 40960)]
Then multiple with number of disks or virtual machines you need and you get total size. Then comes usual discussion LUN SIZE 🙂
