EMC VNXe 3100 Expand Shared Folder accross multiple disk arrays

Hi

We have a EMC VNXe 3100 Unisphere which we use for backup. We recently bought a second array of 12 disk having now total of 2 arrays with each 12 1.7 Tb disk in.

We have created a storage pool called backuppool that until recent was 14 TB which is maximum with a Raid 6. On top of this storage pool we have a share folder called backup.

I have attached the second disk array, and I can add the extra disk to our BackupPool Storage pool. When I try to expand the backup folder it cannot see the extra space in the backuppool that I just added.

1. Is there a folder size limitation for share folders?
2. Is it possible og expand shared folders accross multiple disk arrays?

There's a hard limit of 16TB per file system on the VNXe so I suspect that's the limit you've hit. Your best option is to create a new file system and perhaps use a mount point to access the extra space.

hmm, I thought so.

Do I need to create 2 storage pools, one for each rack, with 2 shared folders each looking at each storage pool,

or

can I keep one storage pool and just create 2 shared folders on that pool each maximising available space??

You could do it either way but if you've already added the disk, then that's it - you can't remove the drives without destroying the entire pool. I'd typically prefer to have two pools as it gives me a little bit more flexibility around expansion, but it's only a preference.
