Discos r\u00edgidos NAS<\/a> do mesmo tamanho.<\/p>\n![\"\"](\"https:\/\/monserveurnas.com\/wp-content\/uploads\/2022\/07\/image-48-1024x618-1.png\")
<\/p>\n
O SHR oferece uma enorme vantagem, uma vez que a mistura de discos r\u00edgidos de diferentes capacidades d\u00e1-lhe a op\u00e7\u00e3o de utilizar inicialmente discos r\u00edgidos pequenos e, eventualmente, atualizar para discos r\u00edgidos maiores, se assim o desejar. Se tiver um NAS de 4 compartimentos e pretender aumentar a capacidade dos discos, pode simplesmente remover um dos discos r\u00edgidos de 4TO e actualiz\u00e1-lo para um disco r\u00edgido de 12TO. Depois de reconstruir o RAID, o seu espa\u00e7o de armazenamento utiliz\u00e1vel ir\u00e1 aumentar para 28TO. Mais uma vez, utilizando o RAID 5, continuaria a ter apenas 12 TB de espa\u00e7o utiliz\u00e1vel.<\/p>\n

<\/p>\n
Resumindo tudo o que acab\u00e1mos de ver, a principal vantagem do SHR do ponto de vista do utilizador \u00e9 a flexibilidade. Se pretende utilizar discos r\u00edgidos do mesmo tamanho e nunca misturar discos, pode utilizar o RAID da sua escolha sem perder espa\u00e7o.<\/p>\n
Tamb\u00e9m \u00e9 importante notar que o SHR \u00e9 tolerante a falhas. Isto significa que se perder um dos discos r\u00edgidos devido a uma falha mec\u00e2nica, poder\u00e1 reconstruir completamente o seu RAID. Este \u00e9 um ponto importante a compreender, pois pode parecer que a perda de um disco r\u00edgido de 12 TB no nosso exemplo acima resultar\u00e1 na perda de dados, quando n\u00e3o \u00e9 esse o caso. Depois de adicionar o novo disco r\u00edgido, o sistema RAID ir\u00e1 reconstruir-se corretamente.<\/p>\n
Finalmente, o SHR pode ser criado com um m\u00ednimo de dois discos r\u00edgidos com prote\u00e7\u00e3o completa contra falhas. O RAID 5, por outro lado, deve ter pelo menos tr\u00eas discos r\u00edgidos. Esta \u00e9 uma diferen\u00e7a importante, uma vez que oferece a possibilidade de utilizar apenas 2 discos num NAS de 4 compartimentos para come\u00e7ar.<\/p>\n

<\/p>\n
Como \u00e9 que o Synology SHR funciona?<\/h2>\n
Uma matriz RAID tradicional utiliza apenas o disco mais pequeno num conjunto de armazenamento, o que significa que os discos de maior capacidade utilizar\u00e3o sempre o espa\u00e7o de armazenamento do disco r\u00edgido mais pequeno por predefini\u00e7\u00e3o quando o RAID \u00e9 criado. A \u00fanica forma de aumentar o tamanho do conjunto de armazenamento seria tornar todos os discos do mesmo tamanho.<\/p>\n
O SHR \u00e9 diferente na medida em que divide o espa\u00e7o de armazenamento do disco r\u00edgido em partes mais pequenas que permitem a utiliza\u00e7\u00e3o de espa\u00e7o de armazenamento adicional.<\/p>\n
Conclus\u00e3o<\/h2>\n
Se pretender obter informa\u00e7\u00f5es um pouco mais t\u00e9cnicas sobre o funcionamento do SHR, encontrar\u00e1 mais informa\u00e7\u00f5es no site da Synology, mas para o utilizador comum que pretende configurar a sua primeira matriz RAID, o importante \u00e9 compreender o resultado que proporciona em termos de espa\u00e7o de armazenamento utiliz\u00e1vel.<\/p>\n
O SHR oferece flexibilidade. Se a flexibilidade n\u00e3o for importante para si, ou se n\u00e3o tencionar utilizar discos r\u00edgidos de tamanhos diferentes, n\u00e3o h\u00e1 raz\u00e3o para escolher o SHR, uma vez que o RAID 5 (a partir de 3 discos) oferece velocidades de transfer\u00eancia ligeiramente superiores.<\/p>","protected":false},"excerpt":{"rendered":"
