Description
Product Specification
The Dell 0D90H2 Perc H730P PCI-E 3.0 SAS 12GBPS/SATA 6GBPS Raid Controller is a powerful storage solution for servers and workstations. This controller offers advanced features like RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 to provide data redundancy and protection. It also includes a 2GB NV flash-backed cache to accelerate data transfer rates.
PCI-E 3.0 and SAS 12GBPS/SATA 6GBPS
The Dell 0D90H2 Perc H730P PCI-E 3.0 SAS 12GBPS/SATA 6GBPS Raid Controller utilizes the PCI-E 3.0 interface for faster data transfer rates. The PCI-E 3.0 interface provides a higher bandwidth than its predecessor, the PCI-E 2.0, which translates into faster data transfer rates. The SAS 12GBPS/SATA 6GBPS interface provides faster data transfer rates than its predecessors, the SAS 6GBPS and SATA 3GBPS interfaces. The higher data transfer rates allow for faster access to data stored on the RAID array.
RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10
The Dell 0D90H2 Perc H730P PCI-E 3.0 SAS 12GBPS/SATA 6GBPS Raid Controller supports several RAID levels to provide data redundancy and protection. RAID 0 provides no data redundancy or protection but allows for the fastest data transfer rates. RAID 1 provides data redundancy by mirroring data across two drives. If one drive fails, the other drive can still access the data. RAID 5 provides data redundancy by striping data across three or more drives with parity data. If one drive fails, the data can still be reconstructed from the parity data. RAID 6 provides data redundancy by striping data across four or more drives with dual parity data. If two drives fail, the data can still be reconstructed from the dual parity data. RAID 10 combines RAID 0 and RAID 1 by striping data across mirrored pairs of drives. This provides both fast data transfer rates and data redundancy.
2GB NV Flash-Backed Cache
The Dell 0D90H2 Perc H730P PCI-E 3.0 SAS 12GBPS/SATA 6GBPS Raid Controller includes a 2GB NV flash-backed cache to accelerate data transfer rates. The NV flash-backed cache uses non-volatile memory to store data, which means that the cache is not lost if the system loses power. This helps to ensure that data is not lost in the event of a power failure. The cache is used to temporarily store data that is frequently accessed, which speeds up data access times. The cache can be configured to operate in write-through or write-back modes. Write-through mode writes data to the cache and the disk simultaneously, while write-back mode writes data to the cache first and then writes it to the disk later. Write-back mode provides faster data transfer rates but carries a higher risk of data loss in the event of a power failure.
Finally, the Dell 0D90H2 Perc H730P PCI-E 3.0 SAS 12GBPS/SATA 6GBPS Raid Controller is a powerful storage solution for servers and workstations. It utilizes the PCI-E 3.0 interface and SAS 12GBPS/SATA 6GBPS interface to provide faster data transfer rates. It supports several RAID levels to provide data redundancy and protection, including RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10.
