GÉANT receives the contract to hyperconnect European supercomputers 🎉

The EuroHPC Joint Undertaking (EuroHPC JU) awarded GÉANT a contract to provide ultra-high bandwidth, secure, pan-European, interconnect services for the EuroHPC #supercomputing infrastructure.

Together, EuroHPC JU, GÉANT and the European NRENs are taking a major step in strengthening Europe’s supercomputing ecosystem, and safeguarding Europe’s digital sovereignty.

I 💝 OpenZFS

Working on research for a HPC storage cluster, one of my architecture doc sections quote this information from the wonderful group at Klara:

> OpenZFS In the Wild
>
> .. Lawrence Livermore National Laboratory (LLNL) undertook porting ZFS to Linux, to form the backbone of their Lustre distributed filesystem. They noted that OpenZFS facilitated building a storage system that could support 1 terabyte per second of data transfer at less than half the cost of any alternative filesystem.
>
> Based on the success seen at LLNL, Los Alamos National Laboratory (LANL) started using ZFS as well.
>
> In the latest example, just a few months ago the U.S. Department of Energy’s Oak Ridge National Laboratory announced it had built Frontier, the world’s first exascale supercomputing system and currently the fastest computer in the world, backed by Orion, the massive 700 Petabyte ZFS based file system that supports it. This impressive system contains nearly 48,000 hard drives and 5,400 NVMe devices for primary storage, and another 480 NVMe just for metadata.
