Storage Manager for SANs
The Storage Manager for SANs (also called Simple SAN) snap-in enables you to create and ma nage the
LUNs that are used to allocate space on storage arrays. Storage Manager for SANs can be used on
SANs that support Virtual Disk Server (VDS). It can be used in both Fibre Channel and iSCSI environments.
For more information on Storage Manager for SANs, see the online help. A Microsoft document titled

NOTE:
Storage Manager for SANs is only available on Standard and Enterprise editions of Windows Storage
Server 2003 R2.
Single Instance Storage
Single Instance Storage (SIS) provides a copy-on-write link between multiple files. Disk space is recovered
by reducing the amount of redundant data store d on a server. If a user has two files sharing disk storage
by using SIS, and someone modifies one of the files, users of the other files do not see the changes. The
underlying shared disk storage that backs SIS links is maintained by the system and is only deleted if
all the SIS links pointing to it are deleted. SIS automatically d etermines that two or m ore files have the
same content and links them together.
NOTE:
Single Instance Storage is only available on Standard and Enterprise editions of Windows Storage
Server 2003 R2.
