The "Unified Field Theory" of Storage

This guest blog was contributed by William Rocca of OS NEXUS. OS NEXUS makes the Quantastor Software Defined Storage platform designed to tackle the storage challenges facing cloud computing, Big Data and high performance applications.

Over the last decade, the creation and popularization of SAN/NAS systems simplified the management of storage into a single appliance so businesses could efficiently share, secure and manage data centrally. Fast forward about 10 years in storage innovation, and we're now rapidly changing from a world of proprietary hardware sold by big-iron vendors to open-source, scale-out storage technologies from software-only vendors that make use of commodity off-the-shelf hardware. Some of the new technologies are derivatives of traditional SAN/NAS with better scalability while others are completely new. Object storage technologies such as OpenStack SWIFT have created a foundation for whole new types of applications, and big data technologies like MongoDB, Riak and Hadoop go even further to blur the lines between storage and compute. These innovations provide a means for developing next-generation applications that can collect and analyze mountains of data. This is the exciting frontier of open storage today.

This frontier looks a lot like the "Wild West." With ad-hoc solutions that have great utility but are complex to setup and maintain, many users are effectively solving one-off problems, but these solutions are often narrowly defined and specifically designed for a particular application. The question everyone starts asking is, "Can't we just evolve to having one protocol ... one technology that unites them all?"

If each of these data storing technologies have unique advantages for specific use cases or applications, the answer isn't to eliminate protocols. To borrow a well-known concept from Physics, the solution lies in a "Unified Field Theory of Storage" — weaving them together into a cohesive software platform that makes them simple to deploy, maintain and operate.

When you look at the latest generation of storage technologies, you'll notice a common thread: They're all highly-available, scale-out, open-source and serve as a platform for next-generation applications. While SAN/NAS storage is still the bread-and-butter enterprise storage platform today (and will be for some time to come) these older protocols often don't measure up to the needs of applications being developed today. They run into problems storing, processing and gleaning value out of the mountains of data we're all producing.

Thinking about these challenges, how do we make these next-generation open storage technologies easy to manage and turn-key to deploy? What kind of platform could bring them all together? In short, "What does the 'Unified Field Theory of Storage' look like?"

These are the questions we've been trying to answer for the last few years at OS NEXUS, and the result of our efforts is the QuantaStor Software Defined Storage platform. In its first versions, we focused on building a flexible foundation supporting the traditional SAN/NAS protocols but with the launch of QuantaStor v3 this year, we introduced the first scale-out version of QuantaStor and integrated the first next-gen open storage technology, Gluster, into the platform. In June, we launched support of ZFS on Linux (ZoL), and enhanced the platform with a number of advanced enterprise features, such as snapshots, compression, deduplication and end-to-end checksums.

This is just the start, though. In our quest to solve the "Unified Field Theory of Storage," we're turning our eyes to integrating platforms like OpenStack SWIFT and Hadoop in QuantaStor v4 later this year, and as these high-power technologies are streamlined under a single platform, end users will have the ability to select the type(s) of storage that best fit a given application without having to learn (or unlearn) specific technologies.

The "Unified Field Theory of Storage" is emerging, and we hope to make it downloadable. Visit OSNEXUS.com to keep an eye on our progress. If you want to incorporate QuantaStor into your environment, check out SoftLayer's preconfigured QuantaStor Mass Storage Server solution.

Adding 'Moore' Storage Solutions

In 1965, Intel co-founder Gordon Moore observed an interesting trend:"The complexity for minimum component costs has increased at a rate of roughly a factor of two per year ... Certainly over the short term this rate can be expected to continue, if not to increase."

Moore was initially noting the number of transistors that can be placed on an integrated circuit at a relatively constant minimal cost. Because that measure has proven so representative of the progress of our technological manufacturing abilities, "Moore's Law" has become a cornerstone in discussions of pricing, capacity and speed of almost anything in the computer realm. You've probably heard the law used generically to refer to the constant improvements in technology: In two years, you can purchase twice as much capacity, speed, bandwidth or any other easily-measureable and relevant technology metric for the price you would pay today and for the current levels of production.

Think back to your first computer. How much storage capacity did it have? You were excited to be counting in bytes and kilobytes ... "Look at all this space!" A few years later, you heard about people at NASA using "gigabytes" of space, and you were dumbfounded. Fastforward a few more years, and you wonder how long your 32GB flash drive will last before you need to upgrade the capacity.

As manufacturers have found ways to build bigger and faster drives, users have found ways to fill them up. As a result of this behavior, we generally go from "being able to use" a certain capacity to "needing to use" that capacity. From a hosting provider perspective, we've seen the same trend from our customers ... We'll introduce new high-capacity hard drives, and within weeks, we're getting calls about when we can double it. That's why we're always on the lookout for opportunities to incorporate product offerings that meet and (at least temporarily) exceed our customers' needs.

Today, we announced Quantastor Storage Servers, dedicated mass storage appliances with exceptional cost-effectiveness, control and scalability. Built on SoftLayer Mass Storage dedicated servers with the OS NEXUS QuantaStor Storage Appliance OS, the solution supports up to 48TB of data with the perfect combination of performance economics, scalability and manageability. To give you a frame of reference, this is 48TB worth of hard drives:

If you've been looking for a fantastic, high-capacity storage solution, you should give our QuantaStor offering a spin. The SAN (iSCSI) + NAS (NFS) storage system delivers advanced storage features including, thin-provisioning, and remote-replication. These capabilities make it ideally suited for a broad set of applications including VM application deployments, virtual desktops, as well as web and application servers. From what I've seen, it's at the top of the game right now, and it looks like it's a perfect option for long-term reliability and scalability.
