CM670 - Dell Dual Port SAS RAID Controller Module for PowerVault MD3000

Description

The Dell CM670 is an iSCSI RAID Controller, a component designed to facilitate high-performance, network-based storage access for Dell server environments. iSCSI (Internet Small Computer System Interface) is a protocol that allows block-level storage commands and responses to be transmitted over standard TCP/IP networks, effectively extending storage area network (SAN) capabilities over Ethernet. This means servers equipped with the CM670 can access storage devices located on a network as if they were locally attached drives, offering a cost-effective and flexible alternative to Fibre Channel SANs. Beyond its iSCSI connectivity, the CM670 integrates RAID (Redundant Array of Independent Disks) functionality. This allows the controller to manage multiple physical drives, organizing them into logical volumes that provide enhanced data redundancy and performance. Common RAID levels such as RAID 0 (for performance), RAID 1 (for mirroring/redundancy), RAID 5 (striping with parity), and RAID 10 (striped mirrors) are typically supported, enabling administrators to tailor storage configurations to meet specific needs for data protection and throughput. This combination of iSCSI and RAID makes it a powerful solution for consolidating and protecting storage resources. Designed for deployment within Dell servers or as part of Dell storage solutions, the CM670 typically interfaces with the host system via a PCIe slot or may be integrated onto a motherboard. Its primary benefit is enabling servers to leverage network-attached storage with the reliability and performance characteristics of a SAN, while also benefiting from the data protection features of RAID. This makes it suitable for a wide range of applications, including virtualization, file serving, and database storage, where efficient and protected access to shared storage is essential.
