IEEE
Institute of Electrical and Electronics Engineers (read “I-Triple-E”). A
non-profit professional association best known for developing standards
for the computer and electronics industry. In particular, the IEEE 802
standards for local-area networks are widely followed.
I/O
Input/output.
I/O Card (ENC)
The I/O Card (ENC) is installed in a DBX. It provides interface functions
for the Controller Box or Drive Box.
I/O Module (ENC)
The I/O Module (ENC) is installed in a DBS/DBSD/DBL/DBLD/DBF/DBW.
It provides interface functions for the Controller Box or Drive Box.
IOPS
Input/output per second. A measurement of hard disk performance.
initiator
See iSCSI initiator.
IOPS
I/O per second.
iSCSI
Internet-Small Computer Systems Interface. A TCP/IP protocol for
carrying SCSI commands over IP networks.
iSCSI initiator
iSCSI-specific software installed on the host server that controls
communications between the host server and the storage system.
iSNS
Internet Storage Naming Service. An automated discovery,
management and configuration tool used by some iSCSI devices. iSNS
eliminates the need to manually configure each individual storage
system with a specific list of initiators and target IP addresses. Instead,
iSNS automatically discovers, manages, and configures all iSCSI
devices in your environment.
