Difference between controller modules

Question

Guys, My company just bought PS4110 and PS6110 SANs. They have controller modules types 14 and 17 respectively, two controllers per SAN. These controllers have 10GbE SFP+ and 10GbaseT ports. Either SFP or 10GbaseT can be used at any given time.  If we replace these controllers for type 10 which has dual SFP ports, is it going to result in performance dergradation?  Type 14 and 17 have 4GB cache as opposed to 2GB in type10.  Besides what about drive compatibility? Does type 10 support NL-SAS drives? THX.

Why do you think you'd want to replace the type 14/17 controllers with type 10? It's highly unlikely that you're maxing out the 10Gbit/s connection (bandwidth).

Type 10 has 2 SFP ports that can be used concurrently.   type 14 and 17 have one SFP and 1one 10GBase ports and I cannot use them concurrently.

Would you guys know if type 10 will be a good upgrade for ps5500e? Seems perfect, right?
