IBM will acquire Storwize, a privately held developer of real-time data compression technology. 
Storwize can compress primary data, or data that clients are actively using, of multiple types — from files to virtualization images to databases — in real-time while maintaining performance. This is in contrast to other storage compression technologies that only compress secondary or backup data. The companies claim the technology can reduce physical storage requirements by up to 80% Financial terms were not disclosed.
Storwize , which is based in Marlborough, MA, claims over one hundred customers, such as Mobileye, Polycom Israel, Shopzilla, Inc. and Sumitomo Mitsui Construction.
