Overview

Unstructured data is growing at an accelerated rate, and IT is feeling the pain. With machine-generated data, user-generated data, and collaborative file data, IT has to deal with more sources and bigger files than ever before. In a recent ESG survey of over 400 IT professionals, including storage directors, storage architects, IT managers, data center architects, and operators working at midmarket (100 to 999 employees) and enterprise (more than 1,000 employees) organizations, the rapid growth and management of unstructured data was cited by the largest percentage of respondents as their primary storage challenge over any other storage issue facing IT (see Figure 1), making it the most popular response.1 Of course, as data volumes grow, protecting that data becomes more challenging, so it is not surprising that data protection came in as the second most cited primary storage challenge.

Exablox Reimagines File Storage Date: April 2013 Author: Terri McClure, Senior Analyst

Abstract: Exablox emerged from stealth mode with a new platform (OneBlox) designed for midsized enterprises with content-intensive applications. It is a scale-out system that can grow with the business, that leverages commodity hardware, and that has some interesting data protection features. It uses an object replication strategy for data protection rather than RAID, so administrators should appreciate the promised fast setup and ease of use, and wont have to worry about miss configuring volumes and LUNs, which is still common to midrange NAS systems today. If OneBlox works as promised, it will be an attractive alternative to todays traditional NAS systems.

When looking at the data from a company size standpoint, midmarket organizations were more likely than enterprise organizations to call out the rapid growth and management of unstructured data, data protection, and running out of physical space as their top storage challenges (see Table 1).2 The fact that midmarket organizations are more concerned with their data protection strategies is consistent with previously conducted ESG research that revealed improved backup and recovery as the top overall most important IT priority reported by midmarket organizations in 2012 and beyond.

It is pretty clear that doing more of the same when it comes to storing unstructured data just isnt going to cut it. The overhead associated with traditional scale-up NAS systems, with limited throughput and drives, LUNs, and volumes to configure, created the challenges IT is having with storing and managing data today. This is especially true for mid-sized organizations that dont have the resources and expertise to spend all their time migrating data between systems to perform storage optimization and management tasks. Next generation storage systems need to be easy, automated, and scale-out to grow with the business. They must be optimized to save space, with deduplication and thin snaps. Of course, they must be highly available, and protect the information. Exablox is promising all this and more with its OneBlox solution.

Exablox Looks to Solve the Unstructured Data Management Challenge

Storage vendor Exablox just came out of stealth mode and claims to have re-architected and reimagined storage. OneBlox is built on its own distributed object-based file system that presents a global file system of CIFS/SMB shares to applications and users coupled with a cloud-based management service called OneSystem. Multiple OneBlox nodes (or rings, as Exablox calls them) enable capacity, performance, and availability to non-disruptively scaleExablox is aiming to ease the management of unstructured data for mid-sized enterprises, and is focusing on capacity-intensive environments like: storing digital assets, and virtual machine archivesthe things that grow like kudzu, and are out-of-hand before users realize they have a problem.

OneBlox

OneBlox is at the core of Exabloxs solution. It is an enclosure with memory and an SSD to handle metadata/indexing (the hash lookup table). It comes with no disk drivesIT can source their own drives and pay commodity pricing (and ride commodity price drops) rather than expensive vendor markups. Drives can be mixed and matched from capacity and performance standpoints, and each node holds up to eight drives. This is a clustered scale-out systemas physical nodes are added it still appears to users as a global file system (even over wide-area distances). This enables users to start with exactly the capacity they need and grow the system with their requirements in a very granular form,

optimizing cash flow and asset utilization. This architecture also means that performance and availability scales with capacity, so you dont suffer from performance bottlenecks as the system scales.

At the core of OneBlox is its new distributed object-based file system, architected from the ground up to be easy, secure, and efficient. The secret sauce behind delivering the advanced functionality at scale is the use of a consistent hashing algorithm. As with some other scale-out file and object storage systems, there are no volumes, LUNs, or RAID groups to configure. The hardware environment is virtualizedas nodes are added (with zero configuration) to the global namespace and absorbed into the system. Then they are presented as additional total capacity available to the users and applications. Thats it. No LUN assignments, configuration changes, or boxes to check. Exablox claims that the initial node can be up and running in about five minutes, and additional nodes added in about three minutes.

Exabloxs file system is full featured and automates a number of tasks. Some of the feature set includes:

Protection from physical failure: Drives fail, users kick plugs out of the wall, someone unplugs a wrong cable. These are the physical failures IT needs to worry about. To protect from physical failure, OneBlox makes three copies of every data object. When a file is written, it ensures that three copies are distributed across the drives in a node (in a single node ring) or across multiple nodes in a ring. In a single node ring, the system can withstand two drive failures. It also means that, in a three node or greater ring, two data paths, drives, controllers, or full nodes can fail without impacting data availability. Because this is not traditional file storage using RAID, rebuild times are accelerated by leveraging all the drives in the system to create new copies of the data objects as required, ensuring every file always has its three copies. Extending the replication capability further, OneBlox can replicate to another ring, over WAN distances, and continue to present a single global namespaceextending protection to entire ring and/or site failures.

Protection from logical errors: When it comes to data protection, logical errors are much more common than physical errorsthings like accidental deletion or software bugs. OneBlox also addresses this issue with inline CDP (continuous data protection) and creates a snapshot every time a file is written to OneBlox. It saves these files as versions, even if a file is accidentally deleted. Every authorized user has access to all versions and can perform a self-service recoveryno need to call IT. CDP is a fully integrated function, enabled by default, and cannot be accidentally turned off by an administrator.

Space efficiency: OneBlox is one of the few solutions that provide inline deduplication of every file written as primary storagethis is a significant advantage of an object-based file system. One would think that there would be tremendous overhead associated with creating a snapshot of every version of a file, but OneBlox leverages inline deduplication across the ring to minimize overall storage consumption and negate the impact of CDP.

Security: When a questionable drive is removed, there is always a concern whether the data on that device is confidential. Exablox uses AES 256 level encryption to secure data at rest. This helps because as drives are removed from the system, they are unreadable. Like CDP and deduplication, encryption is another feature that is enabled by default and cannot be turned off.

Overhead is associated with the data protection methodology used. Because OneBlox creates three copies of data, usable capacity is 33% of total capacity for any new file written. Deduplication will certainly make the equation much betteras storage capacity does not get chewed up by duplicates, so system utilization could be much higher than 33%, depending on the nature of the data stored and how much of it may be all or partially duplicated.

OneSystem

OneSystem is a multi-tenant cloud-based management system used to manage the OneBlox environment. It provides a simple user interface that enables proactive monitoring and management of the entire Exablox environment. Administrators no longer have to deploy onsite management servers, or patch and maintain softwarethey can simply log into OneSystem from anywhere. Managed Service Providers will particularly enjoy the multi-tenancy that enables consistent management across their many customers. This is a unique approach to management (at least for on-premises storage solutions) and should enable Exablox to rev software development more frequently as the physical hardware is decoupled from the management software.

All OneBlox users will use OneSystem, so Exabloxs use of multi-factor authentication is reassuring to ensure another level of security. OneSystem provides management services for the common user, group, and file share permission tasks, but the valuable part is the collective proactive monitoring and reporting it delivers. It removes the configuration complexity of many tasks, which will be a cultural change for many storage administrators.

Of course, there are some trade-offs with making things this easy. The default settings for these features cannot be changed by the administrator. Enterprise storage administrators that want to turn knobs and dials and adjust everything wont be happythis is the antithesis of what high-end systems deliver. But it will be fine for (in fact, desired by) mid-sized enterprises that may not have the staff of storage administrators to handle such tasks.

Market Impact

Exablox certainly addresses many of the pain points storage administrators face today. It invented a system that starts small and grows with the business, is easy to use, leverages commodity hardware, and integrates security and multiple levels of data protection. It almost sounds too good to be true.

No matter how good the technology seems, historically, it has been difficult for any new vendor to gain traction in storage. The brand name vendors have a pretty tight stranglehold on their accounts, and will often do what it takes to keep new vendors out. And storage administrators are (rightfully so) conservative when it comes to deploying new storage technology. An if it aint broke, dont fix it mentality comes with being responsible for the corporate jewels, the data itself. Often, that means making the safe decision and going with the known solution. But things seem to be changing. Many of the core designs behind todays storage systems are (literally) decades old. RAID was invented in the 1980s. The pain points associated with managing data at scale, with accelerated unstructured data growth, and with trying to store and manage that data in systems never designed for these use cases is creating an opportunity for new storage technology to make inroads into IT. There is more willingness to try something new.

Of course, even though it is very cool technology, OneBlox is a new solution. It is not easy to create a scale-out file system that manages data consistency across the cluster. Many have come and gone. Exablox will need to get proof points into the market quickly. Those interested in kicking the tires can get in pretty easily. The system is expected to list at under $10,000 for 32TB. It will be sold through channel partners who can source drives, or the user can source their own drives. This is an interesting point. Administrators are often upset at vendor drive pricing. It is tough to pay vendor drive prices when a 4TB drive sells for just over $200 at Best Buy. Of course, the system vendors will discuss drive qualification and testing and the peace of mind that comes with knowing the drives are well vetted before they go into the system. But the truth is that the secret sauce is in the software, not the drives. And if the software is designed at the start with commodity drives in mind, it can mitigate potential problems. OneBlox appears well suited to take on that challenge.

The Bigger Truth

According to Einstein, the definition of insanity is doing the same thing over and over and expecting a different result. If storage admins try to solve the challenges associated with managing unstructured data with the same technology theyve been using, insanity may certainly be in their future because things just wont get better. Vendors like Exablox are out there with innovative technology that is designed for the unstructured data challenges IT faces today, not the challenges it faced twenty or thirty years ago. And Exablox has an architecture and price point that make it reasonable to bring in as an alternative storage platform to keep the big guys honest. It is a new vendor with new technology, but if it is as easy to use and manage, and functions and performs as promised, those tire kicker installations have the potential to grow into something much more.
