SSD disk wear indicator in E-Series SANtricity 11.70
E-Series SANtricity 11.70 shows wear level for SSD/NVMe disks.

To view it, simply navigate to view physical disk properties.
The indicator shows wear level as amount of performed writes performed so far divided by total supported amount writes for this disk over its lifetime.
Two percent means the disk can take 50x more writes before its considered worn out.
I've never seen a disk with wear level above 10% (or below "90% remaining", on SolidFire arrays.)
