CAIN CXL-Sentry, explained for beginners

CXL-Sentry blocks memory writes outside a tenant's range or without a valid lease.

What it is

In shared-memory hardware setups, one tenant must never write into another's memory. CXL-Sentry checks each requested access before it is granted.

Reads must fall inside the tenant's range. Writes additionally need a valid lease tied to that exact range and time; without it the write is blocked.

An everyday comparison

A safety-deposit box that only opens with today's key for that box.

How it works, in 4 steps

1. An access to a memory range is requested.
2. The range is checked against the tenant aperture.
3. Writes need a valid lease.
4. Otherwise: blocked.
