July 11, 2018: Over the years there have been occasional requests for redundant power supplies for Limulus systems. We also note that there has never been a power supply issue with any Limulus system. We attribute this reliability to proper design and high quality components. While we stand by this record, we are pleased to offer a reasonably priced redundant power supply option on all standard Limulus models (100-400). A similar option is in the works for the larger Limulus systems (Models 1200 and 1300). Finally, a little hint of things to come. What other types of systems like to use redundant power supplies (and sit in a rack chassis)? Stay tuned because the easiest turn-key HPC, Hadoop, and Deep Learning appliance solutions are about to come in another packaging option.
