Huawei V2 and V3 Server RAID Controller Card User Guide 36

This document describes the appearances and features of the redundant array of independent disks (RAID) controller cards, how to configure properties for the RAID controller cards, and how to install drivers. The RAID controller cards include the LSI SAS2208, LSI SAS2308, LSI SAS3008, LSI SAS3108, LSI SoftRAID, PM8060, and PM8068.

Overview

Overview

The LSI SAS3108 controller card is a 12 Gbit/s SAS controller with the MegaRAID architecture. Equipped with PCIe 3.0 x8 ports and a powerful I/O storage engine, the controller card handles data protection, verification, and restoration.

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.

The LSI SAS3108 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.
  • Power failure protection for cache data relies on the supercapacitor of the controller card. For details about the supercapacitor, see the server user guide.
  • The supercapacitor must be used with a trans flash module (TFM). Table 8-1 describes the indicators on the TFM.

The LSI SAS3108 has two structures to provide ease of connection in different servers:

  • LSI SAS3108 for a rack, X8000, X6800 or X6000 V3 server

    The LSI SAS3108 connects to the mainboard through an Xcede connector and connects to the hard drive backplane by using two mini-SAS cables, as shown in (7) of Figure 8-1.

  • LSI SAS3108 for a blade, G560, or X6000 V2 server

    The LSI SAS3108 connects to the mainboard through two Xcede connectors, as shown in (7) of Figure 8-2.
