Linux and Shared Storage

There are many ways to have shared storage. This will only cover SAN attached storage for now.

Linux servers can connect to SANs using 2 types of connectors. iSCSI and Fiber.

Fiber Easier to set up and manage

iSCSI Messier to setup but easy enough

There are also several multipathing options.

PowerPath this is an EMC product that can support various other Storage Vendors.

DM-Multipath Cheap and cheerful does the job nicely but does not have as many bells and whistles as Powerpath. Also slightly messier to setup
