Table 4-74 Parameters

Parameter

Description

Total Capacity

Total capacity of a drive group.

Free Capacity

Remaining capacity of a drive group. The capacity can be used for expanding the existing RAID array or creating a RAID array.

Data Protection

Specifies whether to enable the data protection function for hard drives in a drive group.

Data protection is an advanced feature of RAID controller cards. A unique key for each member hard drive is used to encrypt data by supported hard drives. Such data cannot be accessed from removed hard drives without the key. This function is valid only for hard drives that support data encryption.

Virtual Drives Menu

This menu allows you to view virtual drive properties, modify virtual drive configuration policies, and manage virtual drives.

Screen Introduction

Figure 4-259 shows the Virtual Drives screen. Table 4-75 describes the parameters on the screen.

Type

Parameter

Description

Properties

RAID Level

RAID level.

Status

RAID status.

Strip Size

Volume of hard drive data on each strip.

Default value: 256 KB

Capacity

RAID array capacity.

Parity Size/Mirror Data Size

Parity size or mirror data size.

Policies

Access

Data access policy.

  • RW: The virtual drive is readable and writable.
  • Read Only: The virtual drive is read-only.
  • Blocked: The virtual drive is blocked from access.

I/O

Options for data I/O of special virtual drives. This policy does not affect cache prefetch.

  • Direct: reads data directly without caching it.
  • Cached: caches all the data read.

Read

Options for reading data on a virtual drive.

  • No Read Ahead: disables the Read Ahead function.
  • Always 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

Physical hard drive cache policy.

  • Enable: writes data to the cache before writing data to the hard drive. This option improves data write performance, but data may be lost due to power failure without a power failure protection mechanism.
  • Disable: writes data to a hard drive without caching. Data is not lost in the event of power failure.
  • Unchanged: uses the current cache policy.
NOTE:

The parameter applies only to SSDs.

Disable BGI

Specifies whether to disable background initialization (BGI).

  • No: enables background initialization. In this mode, the background automatically starts initializing virtual drives.
  • Yes: disables background initialization.

Default Write

Data read policy for a virtual drive.

  • Always Write Back: Once all data in the cache is received, the controller notifies the host that data transmission is complete.
NOTE:

In Always Write Back mode, DDR write data of the controller card will be lost if the supercapacitor is not installed or being charged. This mode is not recommended.

  • Write Through: Once the drive subsystem receives all data, the controller notifies the host that data transmission is complete.
  • Write Back with BBU The controller card automatically switches to the Write Through mode when the controller card has no Battery Backup Unit (BBU), the BBU is on charge or discharge, the BBU is faulty, or the controller card has Pinned/Preserved cache. It is recommended that you set the write policy to this mode.
