    Recommendation for a good and fast iSCSI switch

    arista or mellanox should be nice (check if later has os) dell with OS10 is also quite ok, but kinda hard to know you get perpetual, and support reinstatements can be iffy

    SAS, SATA, U.2, NVME, MiniSAS, HBA or RAID, OcuLink?? - Lost in Diversity
