Type 1 and 2 should not co-exist in same JBOD, use both of the same type.
Type 2 is a newer version.
In a mixed type 1 and 2 setup, type 1 have a slow failover ramp up if type 2 fails, causing power interruption to the entire JBOD.
In a both type 1 setup, you can replace a failed type 1 with type 2, ensure type 2 is up and operational, then remove the other type 1, replace it with type 2.

Additional note on "ses show" and "ses show=121?":
'showall' gathers controller side info it does not retrieve all the enclosure info, must use "ses showall" AND "ses show=121?" to get ALL enclosure info. Only one controller is used for ses, typically it is the frist controller in a dual configuration. Only need to retrieve from one controller.
ses showall ses show=121a ses show=121b ses show=121c ses show=121d ses show=121e ses show=121f ses show=121g ses show=121h ses show=121p ses show=121s
The Power Supply SNs are highlight to show it is type 1.
