Производительность софт NVMe рейдов на основе mdadm, LVM и ZFS при использовании iSER и NVMe-oF (100G version) — Part 2

Продолжение первой части, смысл данной статьи сохраняется, а именно показать максимальную производительность, когда вопрос сохранности данных решается репликами или бэкапами. Цель - протестировать производительность трёх систем объединения физических устройств в одно логическое систем при использовании iSER и NVMe-oF. Так как статья получилась объёмная, она поделена на 2 части. В этой части - тесты с использованием HCIbench и iSER\NVMe-oF

Смысл данной статьи показать максимальную производительность, когда вопрос сохранности данных решается репликами или бэкапами. Цель - протестировать производительность трёх систем объединения физических устройств в одно логическое систем при использовании iSER и NVMe-oF. Так как статья получилась объёмная, она поделена на 2 части, в первой идут тесты на уровне локального устройства + вступление. Во второй уже тесты с использованием HCIbench и iSER\NVMe-oF

Русская рулетка дедиков: Собираем RAID 1 + LVM на живой системе без Rescue-режима

Ситуация до боли знакома каждому, кто регулярно арендует выделенные серверы: вы оплачиваете счет, заходите по SSH и видите, что ОС установлена на /dev/sda, а второй диск просто болтается пустым. Никакого RAID, никакой отказоустойчивости. Умрет первый диск — ваши данные исчезнут. Мы в SoftStore идем по пути полного контроля над процессом. В этой статье разбираем пошаговый протокол: как собрать программный RAID 1 и LVM прямо на живой, работающей операционной системе без использования Rescue-режима и переустановки. В качестве бонуса — практика по управлению квотами, снапшотами и замене дисков в Production.

@Gentoo_eV Given that I get a KVM console in time, I will demonstrate my installation guide (https://gentoo.duxsco.de/) in English using a #Hetzner dedicated server.

• What? Beyond Secure Boot – Measured Boot on Gentoo Linux?
• When? Saturday, 2024-10-19 at 18:00 UTC (20:00 CEST)
• Where? Video call via BigBlueButton: https://bbb.gentoo-ev.org/

The final setup will feature:

• #SecureBoot: All EFI binaries and unified kernel images are signed.
• #MeasuredBoot: #clevis and #tang will be used to check the system for manipulations via #TPM 2.0 PCRs and for remote LUKS unlock (you don't need tty).
• Fully encrypted: Except for ESPs, all partitions are #LUKS encrypted.
• #RAID: Except for ESPs, #btrfs and #mdadm based #RAID are used for all partitions.
• Rescue System: A customised #SystemRescue (https://www.system-rescue.org/) supports SSH logins and provides a convenient chroot.sh script.
• Hardened #Gentoo #Linux for a highly secure, high stability production environment.
• If enough time is left at the end, #SELinux which provides Mandatory Access Control using type enforcement and role-based access control
