We are wanting to add a DS2246 to a FAS2620 currently up and running with no Diskshelf. The DS2246 is currently connected to a FAS2240 which is being taken offline soon. Want to verify our cabling plan. The documents can be a bit confusing.
Using: Installation and Service Guide For DS4243, DS2246, DS4486, and DS4246 Jun 2020 and SAS and ACP Cabling Guide For DS4243, DS2246, DS4486, and DS4246 June 2020.
On page 17 I see a connection picture that looks like what we want to do for a 2 Controller single shelf but unsure of how I tell which side of our shelf is IOM A and IOM B?
The other questions I have is how to cable the ACP ports. Looking at picture on page 55 show connections but with multiple shelf's and stacks.
Attached is a ppt of how I think we cable up the new configuration.
Slide 1 is how I think we cable the desired FAS2620 to DS2246 both SAS and ACP cables. I do have a question on the connection from cluster01-02 e0b to cluster01-01 e0b. Not sure if that is needed.
Slides 2 and 3 are using graphic for the same connections as slide 1
Slide 4 is the current our FAS2620 connections with no shelf.
I was asking about the other cables because the current FAS2240 & DS2246 do have those connections. Understand not to move disconnect e0a/e0b on the controller, makes sense as it is for Cluster networking.
Please check the connections for a single shelf with IOM6 connected to a FAS26xx.
SAS adapter 0a of CONTROLLER A should be connected to external shelf DS2246 IOMB SQR PORT SAS adapter 0b of CONTROLLER A should be connected to external shelf DS2246 IOMA CIR PORT
SAS adapter 0a of CONTROLLER B should be connected to external shelf DS2246 IOMA SQR PORT SAS adapter 0b of CONTROLLER B should be connected to external shelf DS2246 IOMB CIR PORT
CONTROLLE A sas port 0b is considered as internal IOM A which shouldn't be connected to IOMB of an external shelf and like wise node CONTROLLER B 0b is considered as internal IOMB which shouldn't be connected to IOMA of an external shelf , if we violates this then we get MixOfIOMAandIOMBConnection_Alert.
