SK Telecom Cloud Storage
Since June 2010, PSPACE worked with SK Telecom as a partner for   developing Storage Technologies for SK Telecom’s Cloud Storage   Services. This project was in the form of SK Telecom’s Technologies   Internalization Project for Cloud Service Technologies.
  PSPACE used InfiniStor as a base system for SK Telecom.
 
The 1st year development was completed in Nov. 2010 and tested in
  SK Telecom Mobile Education Services for testing reliabilities and   acceptabilities tests.
 
After completing 1st stage development, SK Telecom and PSPACE   decided to add security features to InfiniStor.
  That is PSPACE added AES based encryption technologies in InfiniStor.   Thus, when file is stored to DISK, data is encrypted using AES method.
  To enhance the performance of the process, we used Intel’s latest CPU   architecture, Westmere, to make use of AES-NI technology.
  AES-NI is Intel’s latest technology that the CPU already contains AES   instructions in the core of CPU level to speed up CPU consuming work.   Using AES-NI, we were able to enhance the encryption speed by the factor   of 14 times.

  Now, SK Telecom is using TFS, InfiniStor based Storage system, for   various uses of Storage services for both internal and public users.
 
Currently, TFS is used in call recording, distance learning services. Soon, TFS is expected to be used in T-Bag and
  T-Biz Cloud Services.
 
Recently SK Telecom made another contract with PSPACE to develop Block Data Storage System. PSPACE will use PSTORE   as a base platform to develop the block storage system.
  Although PSTORE is not production ready, SK Telecom believe PSPACE can deliver block data storage system by end of Dec.   2011.
  The prototype of PSTORE will be installed and deployed to T-Biz Cloud services for serving Virtualization OS delivery services.
  As InfiniStor, PSTORE will be general purpose storage system and very successful Unified Multi-Protocol systems to debut in the   market by middle of 2012.
  With PSPACE’s Storage technologies, SK Telecom is able to deliver the most reliable and scalable Cloud Storage Services in   limited time and budget.
 
With very close co-development, PSPACE can develop the latest technologies and use SK Telecom’s service infrastructure as a   real test bed. At the same time, SK Telecom can test the latest storage technologies and make request to PSPACE to customize   technologies to fit their needs.
