В качестве примера системы хранения для HPC-приложений, Kingston представила на выставке Supercomputing-2019 стоечное решение с 10 накопителями DC1000M U.2 NVMe, каждый емкостью 7.68 ТБ. Система хранения построена на базе SB122A-PH, платформы форм-фактора 1U фирмы AIC. Процессоры: 2x Intel Xeon CPU E5-2660, память Kingston DRAM 128 ГБ (8×16 ГБ) DDR4-2400 (Part Number: KSM24RS4/16HAI). В качестве ОС установлена Ubuntu 18.04.3 LTS, Linux kernel ver 5.0.0-31. Тест gfio v3.13 (Flexible I/O tester) показал производительность операций чтения 5.8 млн IOPS при пропускной способности 23.8 Гбит/с.
