Eu tenho um servidor onde atualizarei o firmware e os drivers dos controladores RAID da Adaptec em breve, e então eu estava no arcconf para verificar algumas coisas.
Os quatro discos são todos do mesmo modelo configurado como um volume RAID10. Ao executar o GETCONFIG do arcconf, fiquei um pouco surpreso que uma das unidades esteja rodando a 3.0gb / s em vez de 6, como as outras unidades.
Qual poderia ser a razão para isso, e existe uma maneira de fazê-lo funcionar a 6gb / s?

Provavelmente o cabo ATA (DATA) está danificado e o rendimento máximo é de 3 GB / s. Tente trocar o cabo ou se for um hot swap use o slot diferente. Além disso, não há diferenças na unidade de 5,4k RPM e você ainda terá um desempenho decente, por isso praticamente não fará diferença em seu desempenho.
