The competition in storage networking and data management is forever going to get fiercer. And there is always going to be the question of either having open standards APIs or proprietary APIs because storage networking and data management technologies constantly have to balance between gaining a competitive advantage with proprietary APIs or getting greater market acceptance with open standards APIs.
The flip side, is having proprietary APIs could limit and stunt the growth of the solution but with much better integration and interoperability with complementary solutions. Open standards APIs could make the entire market a plain, vanilla one where there is little difference between technology A or B or C or X, and in the long run, could give lesser incentive for technology innovation.
I am not an API guy. I do not code or do development work on APIs, but I do like APIs (Application Programming Interface). I have my fair share of APIs which can be considered open or proprietary depending on who you talk to. My understanding is that an API might be more open if there are many ISVs, developers and industry supporters endorsing it and have a valid (and usually profit-related) agenda to make the API open.
I can share some work experience with some APIs I have either worked in the past or give my views of some present cool APIs that are related to storage networking and data management.
One of the API-related works I did was with the EMC Centera. I was working with Schlumberger to create a file-level archiving/lifecycle management solution for the GeoFrame seismic files with the EMC Centera. This was back in 2008.
EMC Centera does not present itself as a NAS box (even though I believe, IDC lumps Centera sales numbers to worldwide NAS market figures, unless I am no longer correct chronologically) but rather through ISVs and application-level integration with the EMC Centera API. Here’s a high-level look of how the EMC Centera talks to application with the API.
Note: EMC Centera can also present a NAS integration interface through NFS, CIFS, HTTP and FTP protocols, but the customer must involve (may have to purchase) the EMC Centera Universal Access software appliance. This is for applications that do not have the level of development and integration to interface with the EMC Centera API.
