Dell - E2K-UCP-51 PERC 5I PCI-Express SAS RAID Controller with 256MB Cache

Product Description

The Dell PERC 5/i (E2K-UCP-51) is a robust PCI-Express SAS RAID controller engineered to deliver enhanced storage performance and data protection for Dell PowerEdge servers. Equipped with 256MB of onboard cache memory, this controller significantly accelerates read and write operations by buffering frequently accessed data, thereby reducing latency and improving overall system responsiveness. It supports both SAS (Serial Attached SCSI) and SATA (Serial ATA) drives, offering flexibility in drive selection and allowing for the integration of high-performance SAS drives or cost-effective SATA drives. This RAID controller supports essential RAID levels, including RAID 0 for striping (performance), RAID 1 for mirroring (redundancy), RAID 5 for striping with parity (balanced performance and redundancy), and RAID 10 for striped mirrors (high performance and redundancy). These configurations provide crucial data protection against drive failures and can also boost storage throughput. The controller's PCIe interface ensures high-speed communication with the server's motherboard, making it suitable for demanding enterprise workloads. The Dell PERC 5/i is designed for seamless integration into compatible Dell PowerEdge server models. It typically supports hot-plug functionality, allowing drives to be added or removed without shutting down the server, which is critical for maintaining high availability. Management of the RAID array is usually performed through Dell's OpenManage software or the server's BIOS utility, providing administrators with tools for configuration, monitoring, and maintenance of the storage subsystem.
