Hi,

I realize that VNX5200 unlike VNX5600 does not seem to support the 4 drive vault pack e.g. 4 x 300GB SAS for the vault drives. They have minimum and maximum quantity base configs for base DPE 2.5" SAS drives starting from a quantity of 8 up to 25.  Working with a specific requirement for 1 x R6 (14+2) 600GB with 2 spares, I decided that not not waste the drives from the minimum DPE base config of 8 x 600GB , I assume that the system should use the first 4 drives for the vault drives, giving a difference remaining of 4 drives.

I would then add the 4 drives + 18 additional drives =  4 + 18=22 ( 4 vault + ((14+2))+ 2 spares). 1 spare for vault and 1 spare for homogeneous Pool1. 22 drives in all, same size and speed.

Objective and questions:

• Let me know if I can use this format moving forward for vault sizing for the VNXs considering no vault packs for certain models
• What should be take into consideration when using the remaining drives from the default drive starter kits in the config e.g.the 8 to 25 starter kits
• Can the remaining drives from the drive starter kits be used as part of a storage pool and raid group
• My objective is to not waste the remaining drives from the drive starter kits as best as possible. Any advice other than the direction I am taking
• Is a spare disk required for vault drives or not really as I have seen many configs without a vault drive spare

Thanks
