Foi lan\u00e7ado o DRBD 9.1.0, um dispositivo de bloco replic\u00e1vel e distribu\u00eddo que permite implementar uma esp\u00e9cie de array RAID-1, formado por discos de v\u00e1rias m\u00e1quinas interligadas em rede (espelhamento pela rede). O sistema \u00e9 disponibilizado como um m\u00f3dulo para o kernel Linux e \u00e9 distribu\u00eddo sob a licen\u00e7a GPLv2. <\/p>\n

A vers\u00e3o DRBD 9.1.0 pode ser utilizada como uma substitui\u00e7\u00e3o transparente do DRBD 9.0.x e \u00e9 totalmente compat\u00edvel em n\u00edvel de protocolo, arquivos de configura\u00e7\u00e3o e utilit\u00e1rios. As mudan\u00e7as envolvem uma reformula\u00e7\u00e3o do mecanismo de bloqueio e visam reduzir a concorr\u00eancia durante o bloqueio no c\u00f3digo respons\u00e1vel pelas opera\u00e7\u00f5es de entrada\/sa\u00edda no DRBD. Essa altera\u00e7\u00e3o melhorou o desempenho em configura\u00e7\u00f5es com um grande n\u00famero de CPUs e com armazenamento NVMe, ao eliminar um gargalo que impactava negativamente o desempenho durante a ocorr\u00eancia de um grande n\u00famero de requisi\u00e7\u00f5es de entrada\/sa\u00edda em paralelo de diferentes n\u00facleos da CPU. De resto, o DRBD 9.1.0 \u00e9 semelhante ao lan\u00e7amento 9.0.28. <\/p>\n

Lembramos que o DRBD pode ser usado para agrupar dispositivos de armazenamento de n\u00f3s de cluster em um armazenamento resiliente. Para aplica\u00e7\u00f5es e sistemas, esse armazenamento aparece como um dispositivo de bloco id\u00eantico para todos os sistemas. Ao utilizar o DRBD, todas as opera\u00e7\u00f5es com o disco local s\u00e3o enviadas para outros n\u00f3s e sincronizadas com os discos de outras m\u00e1quinas. No caso de uma falha de um n\u00f3, o armazenamento continuar\u00e1 automaticamente a operar com os n\u00f3s restantes. Quando o n\u00f3 com falha se torna dispon\u00edvel novamente, seu estado ser\u00e1 automaticamente atualizado para a vers\u00e3o mais recente. <\/p>\n

O cluster que forma o armazenamento pode incluir v\u00e1rias dezenas de n\u00f3s, localizados tanto na rede local quanto geograficamente distribu\u00eddos em diferentes centros de dados<\/a>. A sincroniza\u00e7\u00e3o em tais armazenamentos distribu\u00eddos \u00e9 realizada utilizando tecnologias de rede mesh (os dados se espalham de um n\u00f3 para outro). A replica\u00e7\u00e3o dos n\u00f3s pode ser feita tanto em modo s\u00edncrono quanto ass\u00edncrono. Por exemplo, n\u00f3s localizados podem usar replica\u00e7\u00e3o s\u00edncrona, enquanto para locais remotos pode ser aplicada replica\u00e7\u00e3o ass\u00edncrona com compress\u00e3o e criptografia de tr\u00e1fego adicionais. <\/p>\n
