How Does Dropbox Store Data?

On my Mac, Dropbox clearly uses a 4 MB "chunk" size for deduplication

Dropbox recently clarified (via their blog and privacy policy) that they “de-duplicate” user files. This has been known for quite a while, and is obvious to anyone who’s had a large file “upload” instantly. But how exactly does Dropbox store files? Are they really de-duplicated or just single-instanced? I set out to discover the answer.

How Apple iCloud Will Challenge the Storage Status Quo

Apple's iCloud is not just MobileMe 2.0!

iCloud is a key enabler of the “post-PC” experience for iOS users. It supports wireless daily backup, storage of purchased music, apps, and books, and synchronization. It also has some interesting Mac OS X features, and it’s free. But the most-compelling feature of iCloud is what it means to future applications on iDevices, the Mac, and even Windows!

Concerning HDS

Where is HDS in VMware's roadmap?

I’ve been following the progress of Hitachi Data Systems (HDS) for well over a decade. When I participated in high-end enterprise storage system shootouts as an end-user, HDS routinely placed second against EMC, HP and NetApp in the, and the decision was always a close one. But the storage market has changed, with nimble startups innovating around established competitors and industry giants flexing their marketing muscles.

How Google and Dropbox Revolutionized My Laptop Migration

My new MacBook Pro was up and running with my data in less than an hour, thanks to Google and Dropbox!

I replaced my trusty MacBook Pro last week, the latest in a series of upgrades stretching back over 25 years. In the past, moving to a new computer is a time-consuming process of installing applications and moving data. But things were different this time: I still had the installs to do, but most of the data migrated on its own.

So there it is. Intel’s Light Peak was launched as Thunderbolt in the new Apple MacBook Pro line. What else happened?

Talking Cloud Storage Gateways With Nasuni and Cirtas

I’ve got a new video podcast up and running: Raising the Floor is a series of discussions about the future of enterprise IT. I kicked the series off talking about one of my favorite topics: Cloud storage. It was a pretty broad discussion, all packed into less than half an hour, but I wanted to share a few excerpts.

My regular series resumes this week.

Oops! This never got posted, what with Thanksgiving and all. So, one week delayed, here are my interesting links from a few weeks back!

Overcoming The Limits Of Thin Provisioning With Automatic Provisioning!

Most thin provisioning solutions are colossal hack jobs. How about real automatic provisioning instead?

I’ve never been a fan of thin provisioning as a storage management tool. Don’t get me wrong, I love having thin provisioning in my toolkit to overcome the limitations of conventional filesystems. Thin provisioning just gets under my skin when folks try to use it to solve business problems like long deployment time and slow purchasing cycles. If you attended any of the thin provisioning sessions I’ve presented at Storage Decisions, Interop, E-Storm, or elsewhere then you’ve heard my wistful dreaming of real automatic provisioning without the hackery of thin provisioning systems. But perhaps I didn’t mention that actual automatic provisioning actually exists today! It’s one of the many things I love about API-driven cloud storage!

Flexible IT and the Path to the Services Future

IT is crossing a chasm, and we may not be prepared for the new direction we are taking

I’m an IT revolutionary. I talk all the time about the quaint backwards “state of the art” in enterprise IT, what with its (many) decades old protocols, paradigms, and practices. What we call modern is really just a charade of faked-out old-fashioned open systems infrastructure: Pretend servers talking to fake disks over frankenstein networking technology.
