I don't know about your overall connectivity requirements. It depends on what you're doing.
However, the Integrated Lights-Out (ILO) is a management port. It is intended for out-of-band management access to the server. ILO should not be used to connect between servers.
For one server, it's potentially a waste of time, depend on the context.
But if you install 2000 server at a time and you don't do a valid "stress test", you are pretty sure to find one server which behave badly.
And it's not only for RAM, it's for network, CPU, hard drive, etc.
When you replace one DIMM, it's a good thing too, just to be sure, the right ...

These SSDs are at least 5 years old and you may be running into other bottlenecks with the controller and design. Don't expect that you'll get the full SSD's performance behind a RAID controller. You may want to ensure your firmware on the server, drives and controller are fully up-to-date, though.
The two drives you mentioned are not the same: They have ...
