Yes. Proprietary CISC chips->MIPS->Itanium and ported to x86-64 around 10 years ago. Apparently is or will soon be offered "in the cloud" as a "NonStop as a Service".
- ghaff 2y agoI forgot about the MIPS step. Went to grad school with a guy who was with Tandem and ended up in charge of HP's enterprise servers. Not sure how network-accessed FT works from a reliability perspective but I guess there are a lot of apps where, if your network is down, you're toast anyway and there are various ways to provide redundancy.
- sillywalk 2y agoI think it's for people who don't want to deal with or upgrade the legacy NonStop stuff. As I understand it, a minimum logical NonStop server is actually pretty extensive: Two standard(?) HPE servers plus two Infiniband fabrics. Also, these servers don't directly connect to anything except the Infiniband. I believe all (or most) IO is offloaded to Clustered IO Modules (CLIMs), which are 1U HPE servers running a custom Linux distro. There are Storage and Network (and I believe Telco) CLIMs. I'm not sure what the minimum number of CLIMs is - e.g. can one provide storage and networking, or if you need two, or for redundancy you need two or four.
- ghaff 2y agoI was an analyst who covered the server space but I sort of lost track of the details of Tandem FT latterly even though I knew the head of HP enterprise server pretty well. As I wrote, a classmate. Originally it was 3 hardware modules voting but that changed latterly and I forget the details. NEC had something as well based on standard hardware as I recall.
