Vitastor \u00e8 un sistema distribuito di archiviazione a blocchi, ovvero uno storage per immagini di macchine virtuali o dischi di container, sviluppato dall'autore dal 2019. A partire dalla versione 1.5.0, \u00e8 anche un filesystem cluster. VitastorFS pu\u00f2 essere montato tramite il protocollo NFS 3.0 su server\/server remoti o locali.    <\/p>\n<p>Vitastor \u00e8 principalmente indirizzato a cluster SSD e SSD+HDD (ma funziona anche con configurazioni solo HDD) con una rete di almeno 10 Gb\/s, supporta TCP e RDMA, e su hardware di qualit\u00e0 pu\u00f2 raggiungere latenze di lettura e scrittura di 4KB di circa ~0.1 ms, circa 10 volte pi\u00f9 veloce rispetto alla maggior parte dei popolari SDS e degli SDS interni dei grandi fornitori di cloud - sia Ceph che i tipici cloud SDS offrono latenze di scrittura di 1-2 ms anche su dischi molto veloci.    <\/p>\n<p>Ad esempio, in un recente test con dischi NVMe Samsung PM9A3 e schede di rete Mellanox ConnectX-4 con RDMA, la latenza ideale di scrittura era &gt; 0.1 ms utilizzando la replica e 0.1 ms in lettura \/ 0.2 ms in scrittura utilizzando codici di correzione degli errori.    <\/p>\n<p>Vitastor supporta il driver QEMU, i protocolli NBD e NFS, i driver Proxmox, Kubernetes CSI e OpenStack. Inoltre, \u00e8 disponibile un operatore Kubernetes sperimentale e un esportatore Prometheus per Vitastor.     <\/p>\n<p>I componenti server di Vitastor sono distribuiti sotto la propria licenza di \"copyleft di rete\" VNPL (Vitastor Network Public License). L'idea della VNPL \u00e8 quella di estendere l'applicazione del copyleft non solo ai moduli direttamente collegati al codice, ma anche ai servizi che interagiscono con Vitastor tramite rete, creati appositamente per esso (ad esempio, qualsiasi wrapper per uso interno nel cloud commerciale).
