There's a growing overlap between HPC and big data, both architecturally and technologically, said Patrick Moorhead, president and principal analyst with Moor Insights & Strategy.
SGI's Ice line of servers makes it a key player in high-performance computing, while its UV line gives it strong big-data capabilities, Moorhead said. In HPC, it boasts "very strong customer relationships that span decades."
"I believe this acquisition will make HPE more competitive in HPC and could do the same in big data," he said. "HPE will need to invest and integrate to make it additive."
The transaction is expected to close in the first quarter of HPE's fiscal 2017, which ends in January.
