This tutorial shows how to set up a high-availability storage with two storage servers (Debian Jessie) that uses GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage nodes. The client system (Debian 8 as well) will be able to access the storage as if it was a local filesystem.

IBM has long been a stalwart supporter of, and participant in the Open Source community. So IBM’s announcement of the LinuxONE platform last year should have come as a surprise to no one. The ultimate goal for LinuxONE, however, may be a bit more surprising.

This tutorial shows you how to setup an AoE client (initiator) and server (target) on Debian 8 /Jessie). The term AoE stands for "ATA over Ethernet" which is a storage area network (SAN) protocol that allows AoE clients to use storage devices on the (remote) AoE server over a normal ethernet network. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE client (initiator), the remote storage looks like a normal, locally-attached hard drive.

Good news! One of my clients is launching a new marketing campaign, which we expect will make the business even more successful than before. Bad news!
