HP 012891-001 Smart Array SAS 128MB PCIe x8 Raid Controller

Product Description

The HP 012891-001 is a Smart Array SAS RAID controller designed to provide essential storage management capabilities for HP ProLiant servers. This controller utilizes a PCIe x8 interface, ensuring high-speed communication with the server's motherboard. It is primarily designed to work with SAS (Serial Attached SCSI) drives, offering reliable performance for business-critical applications. The controller supports a SAS interface speed of 3Gb/s, which is adequate for many server storage needs. This Smart Array controller comes equipped with 128MB of onboard cache memory, which helps to improve the performance of storage operations by buffering data. While it does not support battery-backed or flash-backed write cache, it provides fundamental RAID levels including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), and RAID 10 (a combination of striping and mirroring for both performance and redundancy). These RAID levels offer a good balance of data protection and performance for entry-level to mid-range server environments. Designed for easy integration into HP ProLiant servers, the 012891-001 supports hot-plug drive functionality, allowing for the addition or replacement of drives without shutting down the server. This feature is crucial for maintaining high availability and simplifying maintenance. The controller is managed through HP's standard array configuration utilities, providing straightforward setup and monitoring of the RAID arrays. It represents a cost-effective solution for businesses needing basic SAS RAID capabilities and data protection.
