Many storage solutions provide access over iSCSI, but it is also possible to run a Linux server that
provides an iSCSI target. In this case, it is important to set up a Linux server that is optimized for file
system services. The iSCSI target accesses block devices in Linux. Therefore, it is possible to use
RAID solutions to increase disk space as well as a lot of memory to improve data caching. For more
information about RAID, also see
Chapter 8, “Software RAID Configuration,” on page 79 .
