I picked up one, waiting for delivery

How are you going to use it?

 

[efschu3]

Actual I only need the dual expander SAS backplane.

 

[TedB]

How are you going to use that? Just curious and would like to learn something new

It exposes both ports of a SAS disk, so it can be connected to two hosts. Using this in my actual big.LITTLE cluster project.

Hello geeks,
as I see this enclosure should accept EMC 3.5" FC disks (SCA-40) and output is SAS <-> SAS HBA /RAID contrl.
EMC FC 300G/450G/600Gb size disks should be accepted, right ??

I think Ted is asking, how would someone use this in a regular Intel/AMD server with LSI controllers, or something. Does connect directly via SFF8087 connectors?

Btw, this shelf normally requires 520b formatted disks. Does that requirement change when you yank the backplane?

Can you use normal 512b formatted drives?

Edit: Nevermind, all answered in the thread linked to in the next post below.

It does not. You could have just asked in https://forums.servethehome.com/index.php?threads/emc-ktn-stl3-15-bay-chassis.23244/

But this just uses Fibre-channel drives right? It cant connect standard SAS drives without some interposer?

 

[simoncorner]

It uses SAS disks, the interposer is basically only there to decode some Dell/EMC VNX messages to flash the orange and blue LEDs. You can't connect disks directly to the backplane without redesigning the caddy.
The older chassis KTN-STL4 used FC backplane and FC interposers. It's easy to tell the difference between the interposers as the SAS <> FC ones have a large IC on them and the SAS only ones don't.
