Re: Adding 5886 expansion unit.



fixed

Rob,

If I followed you correctly, yes. The 572F is a 5904/6/8 in the configurator tools depending on mounting only. It is a double wide card with redundant cache so these are not required to be paired like the newer cards. (They can be for additional protection.)

One 572F drives SSDs. I believe those must be on their own controller with these units as you have them.

The other two cards can support up to Five 5886 drawers each.

Obtain another SAS YO cable and use the next available port on one of the the cards used for spinny disks. (working bottom up)

Currently your existing 5886s are daisy chained from the bottom port but they are already two in each chain and that's the limit for each chain.

A cable from one 572F supports one 5886 running four SSD's.
A cable from another 572F supports one 5886 daisy chained to another 5886.
Both running spinning disc's.

I want to add another 5886 for spinning discs.
Can I plug it into an existing 572F, utilizing one of those extra ports?
Can I add this unit concurrently? The following is telling me no.
