are there sas breakout cables and can they be connected to a single B120i controller?

Hi, and thanks for any assist.

I'm managing a souped up Proliant M350e Gen 8 server with RPS and at this point, 4 RAID 1 volumes of various sizes.  Two of these arrays are managed by the onboard B120i controller, and the other two by a PCI connected LSI controller.  3 Pairs are in one drive cage, and the other pair is in another drive cage.

I would like to, if possible , control all available disks from the B120i controller.  The issue is that there is only one system board (SAS type) input to the B210i controller, an there are three connections coming from the drive cages (2 cable from cage 1 and 1 cable from cage 2).  I imagine that's why the LSI controller is currently employed.

Two question are:
1) Is there a SAS type breakout cable to bring all three cage connections to the B120i controller, and...
2) can the B120i controller handle those multiple connections.

Thanks for your insights!

The B120i is based on the Intel chipset fakeRAID controller but running HP's RAID stack. it does not support SAS disks, only SATA. The only reason it has a mini-SAS connector is for simple cabling to the backplane (which does support SAS). It's also limited to 4 drives. HP recommends plug-in Smart Array controllers if you want to use more than 4 disks in the first cage and another Smart Array controller if you want a second cage. They no longer support the SAS expander card that let you connect several cages to a single controller, and they don't do a controller with 4 internal ports to support two cages.

May as well stick to the LSI controller, if you replaced it with a HP one you would have to wipe the disks and start again since HP's stack can't read LSI's metadata or vice versa.

Thanks Andylader

I should have expected I'd need to shell out big bucks for the supported solution.  Well, the LCI controller works, so I;ll go with it.

Thanks again
