HP Medical Archive
Glossary
ADC Administrative Domain Controller—a unit of the HP Medical Archive
software that authenticates grid nodes (certificates) and manages
interconnections. It maintains grid topology information.
ADG Advanced Data Guarding—HP proprietary fault tolerance mechanism
implemented in certain models of HP “Smart Array” RAID storage.
Two sets of parity data are distributed across all drives to protect
against the failure of any two drives in an array.
AE title Application Entity Title—the identifier of a DICOM node communi-
cating with other DICOM AEs.
AMS Audit Management System—a unit of the HP Medical Archive
software that monitors and logs all audited system events and
transactions.
CBID Content Block Identifier—A number that uniquely identifies a piece of
content within the HP Medical Archive system.
CIDR Classless Inter-Domain Routing—a method of routing traffic between
IP networks that improves flexibility when dividing ranges of IP
Addresses into separate networks. CIDR is defined in RFC 1519.
Standard notation for a CIDR address range begins with the network
address, padded with zero bits on the right, followed by a slash “/”
character and a number representing the length in bits of the subnet
mask (prefix), thus defining the size of the network. For example:
• 192.168.120.0/24 represents the 256 addresses 192.168.120.0
through 192.168.120.255 inclusive. The “/24” indicates a 24-bit
subnet mask, leaving 8 bits (0–255) of subnet address space.
• 192.168.212.0/22 represents the 1024 addresses 192.168.212.0
through 192.168.215.255 inclusive. The left-most 22 bits form the
mask, leaving 10 bits (0.0–3.255) of subnet address space.
CIFS Common Internet File System—a file system protocol based on
SMB (Server Message Block, developed by Microsoft) intended to
complement existing protocols such as HTTP, FTP, and NFS.
CLB Connection Load Balancer—a unit of the HP Medical Archive software
that directs incoming DICOM traffic based on factors from an ADC.
CMN Configuration Management Node—a unit of the HP Medical Archive
software for performing system-wide reconfiguration and Grid Tasks.
