Screen Description

Figure 4-305 shows the Advanced screen. Table 4-101 describes the parameters on the screen.

Figure 4-305 Advanced

Table 4-101 Parameter description

Parameter

Description

Parity Size

Specifies the parity block size.

Logical Sector Size

Specifies the logical sector size.

Segment Size

Specifies the strip size.

Starting Logical Block Addressing

Specifies the start address of logical units.

Protected

Specifies whether drive protection is supported.

Bad Blocks

Specifies whether bad block processing is supported.

SSD Caching

Specifies whether SSD caching is supported.

Access

Specifies whether the access policy is supported.

Current Write Cache Policy

Write cache policy used by the RAID array.

  • Write Back: If the supercapacitor is not configured or the supercapacitor is faulty, the RAID controller card automatically switches to the Write Through mode.
  • Write Through: Once the drive subsystem receives all data, the controller notifies the host that data transmission is complete.

Default Write Cache Policy

Default cache write policy of the RAID array.

The values of this parameter vary depending on the firmware version.

  • If the firmware version of the LSI SAS2208 is 3.460.165-8277, the cache write policies are as follows:
    • Write Through: Once the drive subsystem receives all data, the controller notifies the host that data transmission is complete.
    • Write Back: If the supercapacitor is not configured or the supercapacitor is faulty, the RAID controller card automatically switches to the Write Through mode.
    • Always Write Back: Once the cache receives all data, the controller notifies the host that data transmission is complete.
  • If the firmware version of the LSI SAS2208 is 3.400.95-4061, the cache write policies are as follows:
    • Write Through: Once the drive subsystem receives all data, the controller notifies the host that data transmission is complete.
    • Write Back: If the supercapacitor is not configured or the supercapacitor is faulty, the RAID controller card automatically switches to the Write Through mode.
    • Force Write Back: Once the cache receives all data, the controller notifies the host that data transmission is complete.
    Default value: Write Back
    NOTE:
    If this parameter is set to Write Back,, the current write cache policy will automatically change to Write Through when:
    • The RAID controller card does not have a supercapacitor.
    • The supercapacitor is being charged and discharged.
    • The supercapacitor is damaged.
    • Pinned or preserved cache exists.

    If this parameter is set to Always Write Back or Force Write Back, the DDR write data of the RAID controller card will be lost when:

    • The server is powered off unexpectedly.
    • The supercapacitor is not installed.
    • The supercapacior is being charged.

    This mode is not recommended.

Disable Background Initialization

Specifies whether background initialization is disabled.

Read Cache Policy

Specifies the current cache read policy.

  • No Read Ahead: disables the Read Ahead function.
  • Read Ahead: enables the Read Ahead function. The RAID controller card prefetches sequential data or data to be used and stores it in the cache.

Drive Cache

Specifies whether drive caching is supported.

Input/Output

Specifies the I/O read policy.

  • Direct: Data is read directly and not cached.
  • Cached: All read data is cached.

Modifying Virtual Drive Properties

  1. Set Advanced parameters by referring to Table 4-101.
  2. On the Advanced Controller Properties screen, select Apply Changes and press Enter.

    The message "The operation has been performed successfully" is displayed.

  3. Press Enter to complete the configuration.
