Chelsio T6225-CR and SM25G-SR

I recently ordered a Chelsio T6225-CR network interface card and a couple of SM25G-SR SFP28 optical modules.

The aim is to get a 10 Gbit/s connection to the LAN, utilise the off-load capabilities of the NIC, and of course utilise the on-board crypto accelerator. The latter will not be useable until the system moves to the upcoming stable/12 branch.

Speaking of stable/12, I look forward to encrypted crash dumps and linear ZFS scrubbing.

I hope both OpenSSH and OpenSSL will be able to use the crypto accelerator by ways of crypto(4). Imagine a crypto speed in excess of 30 Gbit/s. That’s pretty neat. If all goes well, another T6225-CR may find its way to a VPN router.
