Cloud storage is becoming common place in the industry, but as a storage engineer you will be responsible for providing that storage to the end users.
Background
Data and storage expansion is a challenging task for cloud service providers and data center managers. New technologies can be leveraged to implement storage back-ends, but when you have as much data growth as Google, sometimes you need to think out of the box. The Google File System uses many architecture concepts as RAID, but pushes that up further into the OSI reference model by using software defined storage.
Improvements in hardware technologies are advancing at a rate that Moore's Law that states computers double in complexity every two years is no longer the measuring stick. While the hardware is improving, the demand for faster access to data seems to be more generational. If we look at specific hardware interface standards for hard drives, we've had an evolution from SCSI and IDE drives to newer standards like SAS and SATA. Now M.2 SATA III is becoming more common and will make for smaller storage arrays in the future.
These interface standards that were once hardware based have been encapsulated over TCP/IP to allow for these devices to be accessed over a much greater distance than the cables would allow in the past. Protocols like iSCSC, NFS, FCoE are some of the more common network-based protocols that allow the flexibility to implement distributed storage.
Prompt
Investigate common hardware interface standards and discuss how they are being used to provide data access over high speed networks. How has this enabled systems to change how they add storage space to the enterprise?
