Hi list,
Thanks a lot for your very helpful feedback!

Great hint, but I'm afraid that's too expensive for us. But it's a great
way to scale over the years, I'll keep that in mind.
I had a look at other server vendors who offer 4U servers with slots for
16 disks for 4k in total (w/o disks), maybe that's an even
cheaper/better solution for us. If you had the choice between 16 x 2TB
SATA vs. a server with some SSDs for WAL/indexes and a SAN (with SATA
disk) for data, what would you choose performance-wise?
Again, thanks so much for your help.
Best,
Chris
