Assistance with cabling 3PAR 9450

[CraigV]

Hi All,

Could someone assist me with a cabling up a 2-node 3PAR 9450 to 5 disk enclosures?

Tried to make sense of the cabling guide (which stops at 4 enclosures) and getting stuck.

And this is my first time deploying a 3PAR, so go easy!

Thanks!

It depends on the number of disk ports and if you use direct or daisy chained configuration.

Hi Craig,

More than 4 enclosures is definitely possible in 2 node 3PAR 9450. Each node pair supports up to 12 Drive Enclosures.

Thanks to you both. It would be direct-connect. Each controller node has a 2 x 4-port 12G SAS card installed.

Unfortunately the cabling guide isn't very descriptive and only offers a single configuration type (3 x 4-port SAS with 4 enclosures)

quickspecs say

"HPE 3PAR StoreServ 9000 Storage uses SAS drive adapters for backend drive connectivity. Two SAS adapters are included as part of each controller node. Each SAS adapter on a controller node can connect up to 8 drive enclosures. HPE 3PAR StoreServ 9000 Storage arrays have 12Gbps SAS backend."

Obviously you need another adapter:

Order the following SKU to configure a third SAS adapter on the HPE 3PAR StoreServ 9000 controller nodes. This is optional because each controller node already includes 2 SAS adapters.

HPE 3PAR 9000 4-port 12Gb SAS Host Bus Adapter

Q0E96A

Two (2) SAS adapters are included as part of each controller node
A third optional SAS adapter can be ordered per controller node

I would need a third controller why? Just curious, as it should work with what is there.

I thought you have 9 enclosures, but you have 5, right? All SFF? Even numbers of enclosures are strongly recommended.

You basically cable like this:

slot 2 port 1 - first enclosure

slot 1 port 2 - second enclosure

slot 2 port 3 - third enclosure

1/3 - 4. enc

2/2 - 5. enc

...

It is a dual-node 9450 with 2 x 4-port 12G SAS cards per controller, and 5 enclosures.

Connect like I wrote in the previous post.

Thanks, I will check it out tomorrow.
