Acrescentar HD no servidor ml 110 G7

[JC-Imagem]

Olá,

Comprei há um tempo um ML 110 G7 - Product No. 639264-205 que veio com 1 HD Sata de 250 GB e controladora Sata B110i e quero expandir.

Vi que para usar 2 ou mais Discos SAS em RAID precisarei de controladora.

Qual é a recomendada para o Raid Level 6  ou Level 10?

Modelo encontrado de SAS: HP 581284-B21 - 450GB 6G SAS 10K 2 5in DP Hot Plug

Abaixo a tolerancia de falha suportada para ambos as controladoras e destaquei alguns pontos importantes:

Fault Tolerance

Keeps data available and server running while a failed drive is being replaced; several fault tolerance configurations are supported including: RAID 6 with ADG (Advanced Data Guarding): This is the highest level of fault tolerance. It allocates two sets of parity data across drives and allows simultaneous write operations. This level of fault tolerance can withstand two simultaneous drive failures without downtime or data loss. RAID 6+0: Supported with min of 8 drives, but would have 4 available. Target benefit is to split RAID across the external boxes. NOTE: RAID 6, 6+0 can be enabled with either 256 MB cache, Battery kit and Smart Array Advanced Pack License key option upgrades 512 MB BBWC and Smart Array Advanced Pack License key option upgrades RAID 5 (Distributed Data Guarding): This allocates one set of parity data across drives and allows simultaneous write operations. This level of fault tolerance can withstand a single drive failure without downtime or data loss. NOTE: RAID 5 can be enabled with a minimum 256 MB cache RAID 5+0: This is a RAID 0 array striped across 5 elements. Combines the straight block-level striping of RAID 0 with the distributed parity of RAID 5. RAID 1, 1+0 (Drive Mirroring): This allocates half of the drive array to data and the other half to mirrored data, providing two copies of every file. It is a high-performance RAID.
