HP StorageWorks SAN Virtualization Services Platform 3.0.2 Virtualization Services Manager Demo Mode User Guide (5697-0346, May 2010)

SAN Storage Area Network. A network specifically dedicated to the task of transporting

data between storage systems and servers. SANs are traditionally connected

over FC networks but have also been built using iSCSI technology.

secondary path For an active/passive device, the set of paths that are passive by default.

See also active/passive RAID, passive path, and primary path.

setup virtual disk A virtual disk that contains the virtualized VSM configuration for the SVSP domain,

including, for example, information about storage pools and virtual disks defined

on the domain.

SFP Small form-factor pluggable. The 2 Gbps or faster form factor of the removable

optical transceiver used by the Data Path Module, HBAs, and most Fibre Channel

switches. It uses the LC-type connector.

snapclone A VSM service that creates physical copies of VSM virtual disks without using

host resources.

snapshot Either of the following:

• A VSM service that creates multiple low-capacity, read-write snapshots of

virtual disks and makes the snapshots available to any number of hosts, for

purposes such as data recovery, backup and testing, while the original virtual

disk stays online and continues to be updated.

• A read-write entity that makes PiT data available to any host as a logical

drive.

SNMP Simple Network Management Protocol. The protocol used by the Data Path

Module to report exception conditions to third-party network management

applications.

SSH Secure Shell. A protocol and application for communicating with a remote

computer system. SSH is a more secure alternative to using telnet to communicate

with the Data Path Module.

storage pool In VSM, a set of back-end LUs or stripe sets from which you can create virtual

disks and allocate them to hosts. SVSP storage pools enable you to classify

storage elements into classes of service and provide different classes of service

to different hosts.

stripe set In VSM, a set of back-end LUs across which VSM stripes data, optionally used

to build storage pools.

SVSP domain Consists of all SVSP components and the storage they manage.

synchronous

mirroring

A mode of data mirroring in which the updates on the mirror site are synchronized

between destinations.

system software

image

A software component, capable of being updated, that contains the operating

environment for the Data Path Module, including the SVSP VSM agent for the

Data Path Module.

target Receives commands from the initiator, and after execution, returns

acknowledgement to the initiator.
