[lustre-discuss] What does your (next) MDT look like?

[E.S. Rosenberg]

Hello fellow Lustre users :)

Since I didn't want to take the "size of MDT, inode count, inode size"
thread too far off-topic I'm starting a new thread.

I'm curious how many people are using SSD MDTs?
Also how practical is such a thing in a 2.11.x Data On MDT scenario?
Is using some type of mix between HDD and SSD storage for MDTs practical?
Does SSD vs HDD have an effect as far as ldiskfs vs zfs?

Thanks!
Eli
