In this chapter, we have seen how ready RHEL 7 is for the Enterprise network to act as a SAN server using the new kernel-based iSCSI target server. The management of the server is now made through Python-based tools, such as targetcli, and the targetd service is there to load the configuration at boot. We often provide disk storage on demand from logical volumes. We also looked at how to use three components of LVM to make this happen: physical volumes, volume groups, and logical volumes.

With our storage created and shared, we looked at the second RHEL 7 system and how to connect it as an iSCSI Initiator to utilize this shared storage on the iSCSI target. This was managed initially using iscsiadm, but the connections are persisted through the iscsid service.

In the next chapter, we will take a look at the BTRFS (Better File System), which makes its first appearance on RHEL with version 7. I am sure that you will be impressed with what is on offer with this filesystem.
