bundles can be deselected before installation.
depot A repository of software products, organized so Software Distributor (SD-UX) commands can
use it as a software source.
device identifier A user friendly, readable string, such as “LAB2CAB23LUN15”, that is stored on a device. It

DHCP Stands for Dynamic Host Configuration Protocol, and is a way of dynamically allocating IP
addresses and other network topology information to clients for a specified lease time.
directed boot A boot request that is directed to a particular Ignite-UX server or boot helper system. A directed
boot allows boot and installation from an Ignite-UX server on a different subnet without requiring
a boot helper.
disk group The VxVM equivalent of an LVM volume group.
disk layout The way hard disks are formatted and information stored on them. There are two general
methods of disk layout: physical-storage layout and logical-storage layout. VxVM and LVM
use logical-storage layout, and use various layout techniques such as mirroring and striping.
disk layout
version
The version of the VxFS private data that is used for its file system layout. This term can be
abbreviated to DLVx, where x is the disk layout version number. See mkfs_vxfs(1M).
DNS Stands for Domain Name Service, and provides mapping between hostnames and IP addresses.
DSF Stands for Device Special File. A file associated with an I/O device. DSFs are read and written
