"It's been a little over five years since Hewlett Packard Enterprise (HPE) acquired Cray Computing, a stalwart of the supercomputing world since the 1970s. In that time, the company has grown its pedigree in high-performance computing (HPC) and in June 2025 occupied six of the top 10 spots in the Top500 list of the most powerful supercomputers. HPE Cray Supercomputing GX5000 and K3000"
"In addition to the GX5000, HPE also unveiled the HPE Cray Supercomputing Storage Systems K3000, one of the storage options for the new supercomputing system. According to the company, using K3000 with GX5000 offers 39% higher IOPS per rack compared to the Cray E2000 storage system. K3000 is also, HPE noted, the industry's first factory-built storage system with Distributed Asynchronous Object Storage (DAOS) open source software for software-defined storage."
HPE expanded its high-performance computing portfolio with the Cray GX5000 and K3000 storage system to address enterprise AI infrastructure and data-center efficiency. The GX5000 occupies 25% less rack space than its predecessor while delivering 127% more power per compute slot and supports liquid cooling with warmer inlet water (40ºC vs. 32ºC for the EX4000). The K3000 paired with GX5000 delivers 39% higher IOPS per rack compared to the E2000 and is the industry's first factory-built storage system shipping with Distributed Asynchronous Object Storage (DAOS). GX5000 modules include hot-swappable pump and VFD, left/right agnostic serviceability, and improved air venting.
