The default is 6TB 5400 RPMs for the EX4100-24TB kit.
Looks like 32TB (4x8TB) is supported OOTB but not 40TB.
Are 10TB-Pro supported for this server?
There now seems to be a new series, the PR4100 that does appear to support 40TB (4x10TB).
I do not see anything specific in the specs for the EX4100 that would identify a restriction.
Are there any known issues putting a 10TBPro drive in an EX4100?
