When your ESXi host connects to block-based storage systems, LUNs or storage devices that support ESXi become available to the host.
For each storage adapter, you can display a separate list of storage devices available for this adapter.
Generally, when you review storage devices, you see the following information.
|Storage Device Information||Description|
|Name||Also called Display Name. It is a name that the ESXi host assigns to the device based on the storage type and manufacturer. Generally, you can change this name to a name of your choice. See Rename Storage Devices.|
|Identifier||A universally unique identifier that is intrinsic to the device. See Storage Device Names and Identifiers.|
|Operational State||Indicates whether the device is attached or detached. See Detach Storage Devices.|
|LUN||Logical Unit Number (LUN) within the SCSI target. The LUN number is provided by the storage system. If a target has only one LUN, the LUN number is always zero (0).|
|Type||Type of device, for example, disk or CD-ROM.|
|Drive Type||Information about whether the device is a flash drive or a regular HDD drive. For information about flash drives and NVMe devices, see Working with Flash Devices.|
|Transport||Transportation protocol your host uses to access the device. The protocol depends on the type of storage being used. See Types of Physical Storage.|
|Capacity||Total capacity of the storage device.|
|Owner||The plug-in, such as the NMP or a third-party plug-in, that the host uses to manage paths to the storage device. See Pluggable Storage Architecture and Path Management.|
|Hardware Acceleration||Information about whether the storage device assists the host with virtual machine management operations. The status can be Supported, Not Supported, or Unknown. See Storage Hardware Acceleration.|
|Sector Format||Indicates whether the device uses a traditional, 512n, or advanced sector format, such as 512e or 4Kn. See Device Sector Formats.|
|Location||A path to the storage device in the /vmfs/devices/ directory.|
|Partition Format||A partition scheme used by the storage device. It can be of a master boot record (MBR) or GUID partition table (GPT) format. The GPT devices can support datastores greater than 2 TB. See Device Sector Formats.|
|Partitions||Primary and logical partitions, including a VMFS datastore, if configured.|
|Multipathing Policies||Path Selection Policy and Storage Array Type Policy the host uses to manage paths to storage. See Understanding Multipathing and Failover.|
|Paths||Paths used to access storage and their status. See Disable Storage Paths.|
