Statement of Volatility

Hello, wondering if there's an updated Statement of Volatility posted.

The KB: https://kb.netapp.com/support/s/article/what-are-the-best-practices-for-data-security-covering-complete-system-volatility

has a link that no longer works.

Wondering if there is any way to get written confirmation as to whether there may be information left on the components (specifically the NVRAM & DIMMs) when removed from the machines.

Thanks.
