Understanding OpenStack’s Success
Grazed from Linux Journal. Author: Petros Koutoupis
At the time I got into the data storage industry, I was working with and developing RAID and JBOD (Just a Bunch Of Disks) controllers for 2 Gbit Fibre Channel Storage Area Networks (SAN). This was a time before "The Cloud". Things were different—so were our users. There was comfort in buying from a single source or single vendor. In an ideal world, it should all work together, harmoniously, right? And when things go awry, that single vendor should be able to solve every problem within that entire deployment.
That is why, enterprise companies typically bought from a single storage vendor and invested deeply in them. You either bought HP, Dell, EMC, Sun Microsystems or NetApp, which also was successfully carving a new market in Network Attached Storage (NAS). For example, once an EMC shop, always an EMC shop. Hundreds of thousands to even millions of dollars were spent to ensure that you were enabled for high availability, fault tolerance, training, support and more. Again, through that single vendor.
