Microsoft's Storage Spaces may well be fine for storing family photos and other personal memorabilia but as an enterprise storage tool? Not so much, contends Nexenta CEO Evan Powell in The Register article by Chris Mellor, noting the absence of such features as double and triple parity RAID, the ability to snapshot and replicate data, and the cryptographic-strength 256 bit checksums of ZFS-based solutions found in NexentaStor, which provide end-to-end data integrity. In addition, Powell points out the 16 Terabyte (16 TB) limit in the capacity of Storage Spaces. "It just isn't enterprise class," Powell asserts.

Nexenta's Evan Powell offers 10 open storage predictions for 2012 and, in a commendable mood of candor, grades himself on predictions for 2011. One A+ mark involves his prediction that growth and demand for storage capacity would be exponential. He sees the same for 2012. Powell offers his A+ view that hardware commoditization will play an ever bigger role and awards an A+ for the prediction that sales in the server channel will increase, as he expects them to do in 2012. One last A+, and that is for predicting that Nexenta is the fastest growing storage company ever.

Reporting from the recent OpenStorage Summit, 451 Group analyst Dave Simpson notes a healthy degree of interest in open source alternatives to traditional storage systems. The economies that open source storage technologies such as Nexenta offer have apparently proven sufficiently compelling that Korea Telecom, for example, Asia's largest public cloud provider, has implemented those technologies and offers its services to customers at considerably reduced rates. Simpson also mentions new products from both Nexenta and Symantec, which have attracted considerable interest in the industry. These include NexentaStor 3.1.2 and Symantec's OpenStorage APIs.

The face of storage is changing, and Nexenta's Evan Powell highlights the top 10 drivers of the storage industry in 2011: Part 1 in a recent blog. The first five are:
Capacity demands will continue their exponential rate of growth
IT vendors will appreciate more profit from storage than any other segment
Hardware commoditization (read Nexenta, Supermicro, other OpenStorage solutions) will leave proprietary solutions in the dust
Silent data corruption will grow apace with capacity and users will increasingly turn to solutions like ZFS to checksum everything in order to maintain file integrity.
Developers, impatient with the snail's pace response of corporate IT to their need for SAN and NAS will turn to solutions such as NexentaStor and other open storage solutions to meet those needs. And then there's the cloud. Developers are learning to make an end run around corporate priorities.
