Shared Storage

Shared storage describes a combination of hardware and software used to share data among a
group of users. User systems connect to shared storage devices by way of a server or other
device on a local area network (LAN), or by way of a storage area network (SAN) separate
from the LAN. Shared storage software enables users of these systems to gain access to and
alter data on the shared storage devices. The following figure shows a shared storage
configuration comprising both a LAN and a SAN.
