And why do you think that machine is called a Netra?
Netras were designed for telco use so not for any obvious reason as you suggest. It was available with -48V power supplies.
However, this is precisely the reason why TLS also has the option to use ChaCha20-Poly1305, which will have a decent speed even on an ancient SPARC CPU, though on the most recent CPUs it cannot match the throughput of AES-GCM, which is preferred on these.
So if you want to use a SPARC with TLS 1.3, you must configure it to avoid AES-GCM and use only ChaCha20-Poly1305.
Thank you for saying this. I read this article a few days ago and felt the same: it's a 64-bit gigahertz-class RISC purporse designed internet server with a gig of RAM, running a current OS released less than 4 months ago.
OF COURSE it can host a website. A hundred active ones at once, I should think.
Aix, HP-UX and Solaris, alongside Windows NT/2000 were our production server operating systems.
