Ua paʻi ʻia ka hoʻokuʻu ʻana 1.5.0 o ka ʻōnaehana mālama polokalamu Vitastor me ke kākoʻo ʻōnaehana faila cluster (VitastorFS). He ʻōnaehana mālama poloka i hoʻolaha ʻia ʻo Vitastor, ʻo ia hoʻi kahi ʻōnaehana mālama no nā kiʻi mīkini virtual a i ʻole nā disk ipu, i hoʻomohala ʻia e ka mea kākau mai ka makahiki 2019. E hoʻomaka ana me ka hoʻokuʻu ʻana 1.5.0, kākoʻo pū ia i nā ʻōnaehana faila cluster. Hoʻouka ʻia ʻo VitastorFS ma o NFS 3.0 mai kahi kikowaena e holo ana ma kahi kūloko a mamao paha.
ʻO ke kumu nui o Vitastor ʻo ia nā hui SSD a me SSD + HDD (akā hana pū kekahi i nā hoʻonohonoho HDD-wale nō) me ka liʻiliʻi he 10 Gbps networking, kākoʻo iā TCP a me RDMA, a ma nā lako maikaʻi hiki ke hoʻokō i ka 4K heluhelu a kākau latency o ~ 0.1 ms, ʻo ia hoʻi ma kahi o 10x wikiwiki ma mua o ka hapa nui o nā SDS kaulana a me nā SDS kūloko o nā mea hoʻolako ao nui - ʻo Ceph a me nā SDS ao maʻamau he kākau latency o 1-2 ms ma nā disks wikiwiki loa.
No ka laʻana, ma kahi hoʻāʻo hou me nā drive Samsung PM9A3 NVMe a me nā kāleka pūnaewele Mellanox ConnectX-4 RDMA, ʻo ka latency kākau kūpono he > 0.1 ms me ka hana hou ʻana a me 0.1 ms heluhelu / 0.2 ms kākau me ka ECC i hoʻāla ʻia.
Kākoʻo ʻo Vitastor i ka mea hoʻokele QEMU, nā protocol NBD a me NFS, nā mea hoʻokele Proxmox, Kubernetes CSI, a me OpenStack. Loaʻa pū kekahi mea hoʻokele Kubernetes hoʻokolohua a me ka mea hoʻopuka Prometheus no Vitastor.
Ua hoʻolaha ʻia nā ʻāpana kikowaena o Vitastor ma lalo o kāna laikini "network copyleft", ʻo ia hoʻi ka VNPL (Vitastor Network Public License). ʻO ka manaʻo ma hope o ka VNPL, ʻo ia ka hoʻonui ʻana i ka copyleft ma mua o nā modula i hoʻopili pono ʻia me ke code i nā lawelawe i hana kūikawā ʻia no Vitastor e launa pū me ia ma luna o ka pūnaewele (no ka laʻana, kekahi mau ʻōnaehana hoʻohana kūloko i loko o kahi ao kalepa). A i ʻole, ua kope ʻia ka kikokikona VNPL mai ka GNU GPL 3.0.
