One of the biggest problems for thin provisioning is not the provisioning part: It’s fairly easy for a storage array to allocate on request: “I need a block; here’s some data I want you to write.” And the storage array just starts allocating, and allocating. But, the operating system never goes back and says “I don’t need that block anymore.”

Back From the Pile: Interesting Links, December 24, 2010
Happy end-of-the-year week! I’ll be posting an 11-part series on thin provisioning starting today, but last week was eventful as well. I introduced my enterprise IT events calendar and wrote more about HP’s expiring ink and my HP printer’s demise. It was also time to write about The Four Stages of Vendor Blogging and advising my clients to Always Punch Above Their Weight.
Every Company Is Gunning For Someone Else
One of the amusing aspects of being self-employed is watching all the giants battle it out. Every company is gunning for someone, but the amazing thing is that they rarely have each other in their sights: NetApp is gunning for EMC who’s more focused on HP who wants to knock off Oracle who’s fixated on IBM. It sounds very “high school romance” but this is deadly-serious business.
Caringo Bulks Up CAStor For Cloud Services
Now that the hype of “cloud everything” is subsiding, organizations are getting down to work deploying cloud storage to do actual useful tasks. The march from CAS to cloud to object storage has seen high-profile high-end flare-ups (think EMC Centera and Atmos) but the bulk of work is done by more pedestrian (think lower-cost) hardware and software. Through it all, Paul Carpentier has been at the forefront. Now his company, Caringo, is back in the news, delivering much-needed storage service features like multi-tenancy, named objects, dynamic caching, and web services.
From CAS to Cloud: Revolutionary Storage
Change is not a word normally associated with storage, and revolution is practically unheard of. Today’s modern enterprise storage systems and networks employ massive resources to do one simple thing: Emulate the basic hard disk drives used over three decades ago. But cracks are appearing in our mausoleum of fake disks: Application developers are discovering the value of object storage, and storage systems are appearing to support this need.
