Detecting advance format drives

Client systems are transitioning to Advanced Format (AF) drives for larger storage capacity and to address

the limitations of 512-byte sector hard drives (HDDs). The hard drives transitioning to 4KB sectors

maintain backward compatibility, while the current AF hard drive, known as 512e hard drive, match 512-

byte SATA and operate at 4KB. During the transition, you may encounter performance issues such as,

partition mis-aligned drives in the client systems resulting in failure of sector-based encryption software

packages that handle 512e drives. Command | Monitor allows you to identify if the hard drive on a system

is 4KB AF drive, which helps to prevent these issues.

Boot configurations

A client system can have two boot configurations:

• Legacy (BIOS)

• UEFI

In Dell Command | Monitor, the boot configuration (Legacy or UEFI) is modeled using the following

classes:

• DCIM_ElementSettingData

• DCIM_BootConfigSetting

• DCIM_OrderedComponent

• DCIM_BootSourceSetting

NOTE: The terms "Boot Configuration" and "Boot List Type" are used interchangeably and convey

the same meaning representing Legacy or UEFI.

DCIM_BootConfigSetting

An instance of DCIM_BootConfigSetting represents a boot configuration that is used during the boot

process. For example, on client systems, there are two types of boot configurations — Legacy and UEFI.

So, DCIM_BootConfigSetting has a maximum of two instances to represent, one each for Legacy and

UEFI.

You can determine if the DCIM_BootConfigSetting represents Legacy, using the following properties:

• InstanceID = "DCIM:BootConfigSetting:Next:1"

• ElementName = "Next Boot Configuration Setting : Boot List Type 1"

You can determine if the DCIM_BootConfigSetting represents UEFI, using the following properties:

• InstanceID = "DCIM:BootConfigSetting:Next:2"

• ElementName = "Next Boot Configuration Setting : Boot List Type 2"

DCIM_BootSourceSetting

This class represents the boot devices or sources. The ElementName, BIOSBootString, and

StructuredBootString properties contain a string that identifies the boot devices. For example, floppy,
