Scale IO, SSD or SDS

A large service provider recently signed a multi million-dollar deal with EMC SDS Solutions.  With this type of solution, the customer reduced its storage costs by 25%. This reference confirms the trend that customers are moving more and more towards Software Defined solutions, which aligns with the predictions from IDC, Gartner, Wikibon ....Here are some of my recaps and opinions on ScaleIO, based on what I’ve seen in the industry.


ScaleIO is one of the core Software Defined technologies at EMC. This innovative solution and the disruptive approach require a change in our traditional mindset. ScaleIO is not meant to replace all the workloads in the IT environments, but it’s key to accommodate Next-Gen applications.
 
ScaleIO’s principle is quite simple: a set of x86 servers is aggregated with local drives, which creates a virtual SAN. All the features of traditional storage arrays are preserved and offered at at a lower cost with a simplified management.

ScaleIO offers very high performance and high scalability while reducing management complexity and costs.
