Using iSCSI to share Discs and Tape
SAN for dummies?
I have been working in the Linux industry since before time began -- well, since before Linux began, anyway. I've worked at many of the large Linux/Unix hardware and software companies, such as Bell Labs, HP, AT&T, Sun, and a host of lesser-known names. I've come to love storage: as the internet grows, the bits have to go somewhere! I've worked on drivers for disc drives, HBAs, and tape drives, and now I'm an iSCSI/SCSI expert at SUSE, in the kernel group.
I'm also active outside of SUSE: I'm co-owner of the open-iscsi project, owner of open-isns, and several other projects using C and python.
I love sharing my passion for all things free, including software and beer!
All the tools you need for your own local SAN are available on Linux, including an iSCSI initiator (open-iscsi) and an iSCSI target (LIO) using the targetcli interactive interface. Using these tools, it's easy to share disc drives and even tape units between systems. I will touch on some advanced subjects, such as tcmu-runner, a package that allows users to create their own custom user-space IO back-ends.
