Hello!

There are some considerations around a "memory to flash ratio" (how much flash a controller can address). The CS300 can address 16TB of SSD in total (if I recall correctly) so this might need a touch of consideration depending on the size of shelf you want to add (a 90T shelf includes a 2TB SSD, for example).

Have a chat with your local SE as they should be able to validate this quite easily.

Well teh shelf config was put together by our local NImble/HPE Rep so i hope that is taken into account.  any special conciderations when adding it to the current system??  We are Currently at OS version  5.0.6.0.  Thanks

Then you're all set! adding a shelf is non-disruptive and is a very simple process.... but I always clicking the "activate" button in the GUI out of hours.
