Efter fem \u00e5rs utveckling presenterade Linux Foundation lanseringen av SEAPATH 1.0, en virtualiseringsplattform som har utvecklats med h\u00e4nsyn till kraven f\u00f6r informationssystem f\u00f6r digitala transformatorstationer inom energin\u00e4t. Plattformen tar h\u00e4nsyn till specifikationen av energin\u00e4t, men kan \u00e4ven till\u00e4mpas inom andra omr\u00e5den d\u00e4r h\u00f6g tillf\u00f6rlitlighet kr\u00e4vs. Koden f\u00f6r plattformen publicerades under Apache 2.0-licensen. Utgivningen av SEAPATH 1.0 har bed\u00f6mts vara redo f\u00f6r industriellt bruk och f\u00f6r anv\u00e4ndning i kritiska system. Plattformen anv\u00e4nds redan i den operativa infrastrukturen hos energif\u00f6retaget RTE och genomg\u00e5r en testimplementering hos f\u00f6retag som GE Vernova, Alliander, ABB, Red Hat och Enedis. <\/p>\n

F\u00f6r \u00f6vervakning, automatisering, support och hantering av energifl\u00f6desf\u00f6rdelningen p\u00e5 digitala transformatorstationer inom moderna energin\u00e4t, anv\u00e4nds specialiserade applikationer fr\u00e5n olika leverant\u00f6rer, som f\u00f6resl\u00e5s att k\u00f6ras i separata isolerade virtuella maskiner. SEAPATH implementerar en plattform f\u00f6r att organisera arbetet med s\u00e5dana virtuella maskiner<\/a>, virtualiserade applikationer (vPAC — Virtualized Protection, Automation and Control) d\u00e4r realtidsoperationer kan utf\u00f6ras.

F\u00f6r att implementera noder med v\u00e4rdmilj\u00f6n erbjuder SEAPATH tv\u00e5 distributioner baserade p\u00e5 Debian GNU\/Linux 12 och Yocto Scarthgap. Plattformen \u00e4r inte knuten till n\u00e5gon specifik h\u00e5rdvara, \u00e4r oberoende av enskilda leverant\u00f6rer och kan anv\u00e4ndas p\u00e5 olika typer servrar<\/a> och h\u00e5rdvaruarkitekturer. Det \u00e4r till\u00e5tet att k\u00f6ra applikationer f\u00f6r elektriska transformatorstationer som st\u00f6djer standarden IEC-61850. <\/p>\n

Fel\u00f6vervakning s\u00e4kerst\u00e4lls genom anv\u00e4ndning av klusterkonfigurationer med redundans av h\u00e5rdvara, samt genom lagring av data och bilder av virtuella maskiner i ett distribuerat lagringssystem som replikeras p\u00e5 olika noder i klustret. Uppdateringar installeras automatiskt fr\u00e5n en extern server. Konfigurationshantering och administration sker centralt med anv\u00e4ndning av konceptet infrastruktur som kod. <\/p>\n

Plattformen \u00e4r byggd med hj\u00e4lp av befintliga \u00f6ppna projekt, f\u00f6r vilka en testsvit har f\u00f6rberetts, inklusive mer \u00e4n 700 enhetstester. Virtualisering \u00e4r genomf\u00f6rd med hj\u00e4lp av hypervisor KVM och en Linux-k\u00e4rna som \u00e4r kompilerad med PREEMPT_RT-alternativet f\u00f6r realtidsarbete. Som ett distribuerat lagringssystem som omfattar hela klustret anv\u00e4nds Ceph. F\u00f6r enhetsvirtualisering anv\u00e4nds QEMU, och f\u00f6r n\u00e4tverksvirtualisering — Open vSwitch. Verktyget Libvirt anv\u00e4nds f\u00f6r att hantera virtuella milj\u00f6er. F\u00f6r att hantera resurser i klustret, s\u00e4kerst\u00e4lla redundans och organisera interaktioner mellan noder anv\u00e4nds Pacemaker och Corosync. Centraliserad hantering av infrastrukturen och orkestrering av virtuella maskiner \u00e4r genomf\u00f6rd med hj\u00e4lp av Ansible.
