Tai krub,
New storage (EQL PS6210XV) has configure 24x 600GB 15K.
Best performance should be RAID50 with 2x Hot spare.
Total capacity in new storage is 9.5TB with RAID 50.
Able to use estimate 7.5TB krub,
Because 20%, we need to prepare for snapshot = 2TB
Konica current system.
Capacity from your list 23 servers
In your list Provision Capacity is 11.2TB
but Used Capacity is only 3.8TB
We need to resize your VM before move to new system.
Thank you,
S Pachara.
