In Aruba CX 10000 switches, how many SFP28 port-groups are there?

How many Aruba 100G QSPF28 LC ER4L 40KM SMF Transceivers are allowed on Aruba CX 8325?

In preparation for the deployment, what statement is correct from the below?

2-Tier L2 Design
* 6400 100G Core Switches
* 8320 48-P 10G RJ45 Access Switches
* 40G DAC connections between Core and AccessCore Switches = VSX Pairs of 6400 switches (each with 2 x 12-port QSFP28 100G modules) Each pair uses:
* 2 x 1M 100G DAC for ISL
* 1 x 1M 100G DAC for Keepalive
* 2 x 5M 40G DAC to each access switch
Each Spine switch has 5 x 100G interfaces available.
This solution could scale to a maximum of:

What is the upper limit for spine switches with leaf HPE Aruba CX 8360-48Y6C v2 using 100 or 40 GbE Leaf-to-spine port speed (when using 2 uplink ports for VSX)?
