Product Description
The Dell CN-0TT235 is a specialized backplane board engineered specifically for integration into the Dell PowerEdge R900 server. Its primary function is to serve as an intermediary between the server's internal storage bays and the SAS (Serial Attached SCSI) host bus adapter (HBA) or RAID controller. This backplane board is designed to support multiple SAS drives, enabling configurations that leverage the high performance and reliability of SAS interfaces for storage. The 'SAS x5' designation indicates that the backplane utilizes five lanes of SAS connectivity. SAS is a serial communication protocol designed for high-speed data transfer, offering advantages over older parallel SCSI interfaces in terms of speed, scalability, and error handling. The x5 specification likely refers to the number of SAS lanes it supports or the type of SAS expander/controller it is designed to interface with, ensuring sufficient bandwidth for multiple drives. This backplane board is critical for enabling hot-swap functionality for the installed SAS drives. Hot-swapping allows administrators to replace or add drives without shutting down the server, which is essential for maintaining high availability and minimizing downtime in mission-critical environments. The CN-0TT235 is a key component for expanding the storage capacity and performance of the PowerEdge R900, supporting demanding workloads that require fast and reliable access to data.
