vlan on s3048<->2xs5248f-on<->10xpoweredgeR750

Hi, need help with setup of vlan where I have one s3048 connected to two s5248f-on that are connected to 10 R750 machines and the idea is to create storage cluster in ubuntu. I am new to cisco OS 9 and 10 and so it is a bit tuff to realise anything good just jumping between manuals.

Would appreciate some educational hints how to configure the switches to properly create the vlan for the servers.
