Terminology
Terminology
This document uses the terms new and existing to refer to storage
systems, servers, and host bus adapters (HBAs) as follows:
The document also uses SP to refer to a storage processor in the storage
system. An AX100SCi storage system has only one SP, so it is called a
single-SP storage system. An AX100i storage system has two SPs, so it
is called a dual-SP storage system.
CHAP Challenge Handshake Authentication Protocol. An optional
security mechanism to control access to an iSCSI storage
system over the iSCSI data ports.
Existing NIC or iSCSI
HBA The network interface card (NIC) or host bus adapter (HBA) that is already installed in a server.
Existing server The server that is already configured for and connected to an
AX-Series storage system.
Existing storage system An AX-Series storage system that is already connected to a
server and configured for storage.
Host A computer that is or will be connected to an AX-Series storage
system. This computer is called either a
management host or a
server, depending on how it is or will be connected to the storage
system.
Management host A host from which you manage AX-Series storage systems. It
must be on the same LAN as the storage-system management
ports. A management host may also be server.
Initiator A NIC or iSCSI HBA port that issues requests to send data to or
receive data from a target in the storage system.
New NIC or iSCSI HBA The NIC or iSCSI HBA that was
not already installed in the
server.
New server A server that is not already connected to or set up for an
AX-Series storage system.
New storage system A storage system that is
not connected to a server or configured
for storage. It is just as it was shipped to you.
Server A host that is already or will be connected over a LAN to the
iSCSI ports on a AX-Series storage systems. A server can also
be a management host.
Target A storage system SP port that accepts and responds to requests
from an initiator.
