HP XP P9500 Storage - Manual (Page 609)

an LU that has been reserved is given only to the host that issued the reservation, so
the LU cannot be accessed from multiple paths (coming from multiple hosts)
simultaneously. However, because of this, load balancing is not possible.
S
SAN (Storage Area Network)
A high-speed network connecting hosts to storage systems. This network is independent
of a LAN and is dedicated to data transfers. A SAN provides faster access to storage
systems, and prevents the transfer of high-volumes of data from deteriorating LAN
performance.
SCSI device
A SCSI disk device
SLPR (Storage Logical Partition)
The SLPR function enables logical splitting of a storage system supported by the Hitachi
USP series, Universal Storage Platform V/VM series and Virtual Storage Platform series.
This function splits up the resources, such as ports, CLPR, and volumes, in the storage
system, so that the user can manage each resource independently.
