Copying existing set-up but for off site redundancy, refresh of network equip?

hayd

Hi all

We are replicating a system for off site redundancy, management have asked weather our current equipment is sufficient or if their is new models since been replaced.

Equipment I had been asked to look in to is for the following:

Cisco 2960 24TS-L - still ok
Cisco ASA 5545 - still ok
Cisco IPS 4345 - end of support 2020, potentially look for an alternative
McAfee S4016 - not able to find, mcafee site pages says moved location.
Dell N46064 - is ok

Hopefully someone could shed some light if they think these products could be improved.
