RabbitMQ Cheat Sheet (russian)

Общие упрощенные понятия. Возможно существуют способы задать другое поведение нежели данное упощенное.

Понятия

  • producer - отправитель, программный код, который отправляет сообщение.
  • consumer - получатель, программный код, который должен получить сообшение.
  • exchange - обменник, функционал RabbitMQ, получает сообщение с заданными параметрами от отправителя и:
    • может сбросить(удалить) сообщение или вернуть отправителю (зависит от атрибутов сообщения),
    • может отправить сообщение в очередь,
    • может отправить сообщение в несколько очередей (сообщение будет скопировано для каждой очереди)
  • queue - очередь, функционал RabbitMQ, хранит все сообщения и раздает их получателям.
  • message - сообщение, содержит атрибуты необходимые RabbitMQ, а также данные для передачи от отправителя к получателю

HP Smart Storage Admin CLI (ssacli) installation and usage on Proxmox PVE (6.x)

HP Smart Storage Admin CLI (ssacli) installation and usage on Proxmox PVE (6.x)

Why use HP Smart Storage Admin CLI?

You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.

CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.

ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.
