Comment Re:How do you back up Ceph? (Score 5, Informative) 18 18

(Inktank community guy here)

There are a number of different options for backup/disaster recovery solutions with Ceph, depending on what piece(s) of the platform you are using. For instance, the object gateways (think S3) from multiple clusters can be plugged together for multi-site replication. The CephFS and block device portions both have snapshotting built in that can be replicated offsite.

In the medium-term we're looking at having a way to replicate your entire cluster over the wire at the RADOS level (underlying object store). Longer-term we'd love to be able to offer WAN-scale replication for a single cluster and the ability to snapshot a cluster (or portions/pools therein) easily.

I hope that helps. If you have more questions hit me up on #ceph at OFTC.net IRC.

As one AC already pointed out, you should check out Ceph (full disclaimer: I work for Inktank now, the consulting services company that employs most of the core Ceph devs). Ceph is, at its heart a Distributed Object store, but we allow you to access in a number of different ways:
  • * Native API
  • * Via a RESTful interface that can handle native Amazon S3 and Swift API calls
  • * As a thinly provisioned block device
  • * Mount it as a POSIX-compliant file system via CephFS (although this is a bit rough for production environments just yet)

Josh Durgin has actually done some really interesting work in using the block device (RBD) to back Cinder which you can read a bit about here.

The cool part about Ceph is it was designed to be massively scalable (petabytes and beyond) and extremely fault tolerant / HA / etc. DreamHost actually just built out a huge production deployment of Ceph and OpenStack for their new DreamCompute / DreamObjects offering. If you have questions feel free to hit up the #Ceph irc channel at irc.oftc.net or poke me via email (my UN at inktank.com) and I'll see if I can't find the right person to help.

OpenStack really has some awesome potential, and we're excited about poking at it more with our semi-sharp Ceph-stick. Good luck.

Now that Ceph is gathering momentum since having been included in the mainline kernel, what other storage (or low level) advancements do you see on the horizon?

Submission + - Intel and Micron Unveil 128Gb 20nm NAND Flash->

ScuttleMonkey writes: "A joint venture between Intel and Micron has given rise to a new 128Gb die. While production wont start until next year and distribution mostly likely not until 2013, this little beauty sets new bars for capacity, speed, and endurance. "Die shrinks also tend to reduce endurance, with old 65 m MLC flash being rated at 5,000-10,000 erase cycles, but that number dropping to 3,000-5,000 for 25nm MLC flash. However, IMFT is claiming that the shrink to 20nm has not caused any corresponding reduction in endurance. Its 20nm flash uses a Hi-K/metal gate design which allows it to make transistors that are smaller but no less robust. IMFT is claiming that this use of Hi-K/metal gate is a first for NAND flash production.""

Submission + - Startups a Safer Bet Than Behemoths->

ScuttleMonkey writes: "TechCrunch's Vivek Wadhwa has a great article that takes a look at difference between startups and "established" tech companies and what they each mean to the economy and innovation in general. Wadhwa examines statistics surrounding job creation and innovation and while big companies may acquire startups and prove out the business model, the risk and true innovations seems to be living at the startup level almost exclusively. 'Now let’s talk about innovation. Apple is the poster child for tech innovation; it releases one groundbreaking product after another. But let’s get beyond Apple. I challenge you to name another tech company that innovates like Apple—with game-changing technologies like the iPod, iTunes, iPhone, and iPad. Google certainly doesn’t fit the bill—after its original search engine and ad platform, it hasn’t invented anything earth shattering. Yes, Google did develop a nice email system and some mapping software, but these were incremental innovations. For that matter, what earth-shattering products have IBM, HP, Microsoft, Oracle, or Cisco produced in recent times? These companies constantly acquire startups and take advantage of their own size and distribution channels to scale up the innovations they have purchased.'"

Submission + - Tracking Water Molecule Could Unlock Secrets->

ScuttleMonkey writes: "ScienceDaily is reporting that several new discoveries about the simple molecule of water have kicked off a surge in research that scientists believe could lead to solving some of the world's most tricky problems from agriculture to cancer. "Understanding how individual water molecules maneuver in a system to form fleeting tetrahedral structures and how changing physical conditions such as temperatures and pressures affect the amount of disorder each imparts on that system may help scientists understand why certain substances, like drugs used in chemotherapy, are soluble in water and why some are not. It could also help understand how this changing network of bonds and ordering of local tetrahedrality between water molecules changes the nature of protein folding and degradation. 'Understanding hydrophobicity, and how different conditions change it, is probably one of the most fundamental components in understanding how proteins fold in water and how different biomolecules remain stable in it,' says Kumar. 'And if we understand this, we will not only have a new way of thinking about physics and biology but also a new way to approach health and disease.'""

NotAnIndividual writes: On an ice fishing trip two months ago, I lost my iPhone somewhere in the snow. I searched and searched, but to no avail. But just this weekend when moving the ice hut, lo and behold there it was. I quickly threw it into a bag of rice and placed it under a lamp to defrost. Three hours later I plugged it in. I wasn't expecting much. I mean, really, it had been frozen in snow for the last two months! To my surprise, the Apple logo popped up. I put in the SIM card and voila, my iPhone was back. My apps, my contacts, my music and more importantly my life were back. And this is the same iPhone that I dropped in a cup of coffee a few months ago! This got me wondering how much damage a cell phone can actually take.

How have other slashdot users punished their phones without actually killing them completely?
