Product Description
The IBM 00D7081 ServeRAID M1100 Series controller is a PCI Express-based RAID controller that distinguishes itself by being a 'Zero Cache' model. This means it does not feature onboard cache memory, which is typically used to accelerate read and write operations in higher-end RAID controllers. Instead, it relies on the host system's memory and CPU for some processing, making it a more cost-effective solution for basic hardware RAID needs. Despite the lack of cache, the 00D7081 still provides hardware RAID capabilities, supporting essential RAID levels such as RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), and RAID 10 (striped mirrors for a balance of performance and redundancy). This allows for fundamental data protection and performance improvements over software RAID or single-drive configurations, without the added cost of dedicated cache modules. Designed for IBM systems, this controller is suitable for entry-level servers or applications where the highest I/O performance is not critical, but basic hardware RAID protection is desired. Its PCI Express interface ensures compatibility with modern server architectures. The IBM 00D7081 offers a straightforward and economical way to implement hardware RAID for SAS and SATA drives in IBM environments.
