cluster for a customer who is planning to use vRealize Automation to provision 600 virtual machines into that cluster, with expected growth up to 1,000 VM. Each VM has a 40GB thick-provisioned disk.
Which flash disk size is required for the cache tier per ESXi node to meet all requirements?
- A. 400GB
- B. 600GB
- C. 800GB
- D. 700GB
Answer: C
Explanation:
40GB x 1000VMs = 40 000 GB total max expected usage 40 000GB / 5 node cluster = 8000 GB per node cache should be 10% so 800GB SSD is needed. However this question is stupid from real life perspective. one host can run up to 200 VMs - so what with MM, any failure ? Cluster should be sized with 6 ESXi hosts minumim
