It is completely loaded and working in a production environment.
We have got a new Disk Enclosure (14disks)and we wish to add it to existing configuration.
Whether a question it is possible to add a new Disk Enclosure (14disks)not disconnecting EVA (shtudown array), and on how many it risky to add Disk Enclosure on powered EVA4000
Solved! Go to Solution.

8- free space from here up
7- 2U Controller B
6- 2U Controller B
5- 2U Controller A
4- 2U Controller A
3- 3U Disk Shelf
2- 3U Disk Shelf
1- 3U Disk Shelf
If you plan on upgrading to more disk shelves later on, you may want to move the controllers up to U7-10 and/or if you think you might upgrade to a 6000, move them up to U14-17.
Eitherway, always hae a backup of all your data.

Re: EVA4000 2C1D, adding new Disk Enclosure
Now total we have 2 disk enclosure an 28 disks
each disk is: 136.73Gb
136.73 x 28 = 3,828.44
But on EVA, Storage Capacity Total space is: 3332.41
EVA Operational Status is Good, no pending operations
All 28 Disk is groped in 1 disk group, all disk status is Online and Grouped.
3828.44 - 3332.41 = 496.03
and we lost = 496.03 Gb, where 496 Gb gone?

What is your Disk Protection set to? None? Single? or Double? Looks like single to me with the difference being overhead/metadata/miscalculation.
Single protection, you lose an additional 2x136.73 (273.46)
Double protection, you lose an additional 4x136.73 (546.92).

Re: EVA4000 2C1D, adding new Disk Enclosure
On the upgraded EVA, if you did not create or expand any virtual disks yet, then you should have the occupancy that you had beforethe upgrade.
As for why you lost 500GB, I am unsure.
