Overview

Overview

A PM8060 RAID controller card provides two 12 Gbit/s SAS wide ports and supports PCIe 3.0 ports.

In addition to better system performance, the controller card supports fault-tolerant data storage in multiple hard drive partitions and read/write operations on multiple hard drives at the same time. This makes accessing data on hard drives faster.

A PM8060 RAID controller card supports boot and configuration in legacy and UEFI modes.

The built-in cache improves performance as follows:

  • Data is directly written to the cache. The controller card then updates accumulated cache data to hard drives in batches. Overall data write speed is higher since writing to the cache is faster than writing to the hard drive.
  • Data is directly read from the cache, reducing the response time from 6 ms to less than 1 ms.

The controller card is installed on PCIe slots of a server and its appearance is shown in Figure 10-1.
