Containers have the potential to be hugely disruptive – they are about to impact almost every process and person within the data center. Container technology will also impact how we think about storage for applications and microservices. In turn, software defined storage will impact how storage is dynamically provisioned and managed for containerized applications.

According to the OpenStack Foundation’s sixth and most recent user survey released just prior to this week’s OpenStack Summit in Tokyo, 62% of users selected Ceph RBD block storage for their OpenStack use cases, nearly three and more than four times the two closest alternatives, LVM (default) and NetApp, respectively. In production, a full 38% of respondents indicated that their OpenStack deployments depended on Ceph as their Cinder driver, with the same comparisons. A survey of the largest production clouds, those exceeding 1,000 cores, showed similar results, with 37% of users selecting Ceph RBD followed by NetApp at 12%. Interestingly enough, with 9% of respondents using GlusterFS in production, development & quality assurance, or proof of concept across all OpenStack deployments, more than 70% of OpenStack users are relying on block storage championed by Red Hat Storage.

Enterprises are dealing with workloads that demand anywhere from a few terabytes to multiple petabytes of unstructured data. Storage-intensive enterprise workloads are ubiquitous in the data center and range across workloads such as:

This week at OpenStack Summit in Vancouver, Red Hat announced integrated OpenStack Manila shared file system services with Red Hat Gluster Storage to provide enterprises with a scale-out file system for OpenStack clouds.
This news is extremely relevant to enterprises that need a scale out shared file service for their private cloud deployments. Before the Manila file share service, there was no elegant way to handle file shares in OpenStack. The integration with OpenStack Manila allows Red Hat Gluster Storage to serve as a storage back end for Manila, giving users a way to take advantage of file-based storage services in an OpenStack environment. In addition, it takes away much of the housekeeping chores from OpenStack users who can now request a file share, use it as long as needed and place it back into the storage pool, without ever caring about who first created the file or where exactly it’s stored.

OpenStack Manila file storage users have a reason to celebrate. Red Hat is proud to announce a new performance benchmark that not only reinforces the performance of GlusterFS at scale but also demonstrates how enterprises could significantly lower enterprise storage and energy costs.
The benchmark tests represent the industry’s first results of GlusterFS on ultra-dense Cisco UCS C3160 servers with high-speed networking. GlusterFS offers over half a petabyte of usable storage with just four nodes, which makes it is extremely cost effective in storage intensive workloads such as OpenStack Manila. The latest IOzone file system performance benchmark shows how GlusterFS read and write performance scale near linearly when deployed on Cisco UCS 3160 servers.

According to a voluntary online survey conducted by the OpenStack User Committee, many of OpenStack’s founding projects, including Nova and Glance continue to be popular. However, other projects, such as Heat, Swift, and Trove, are also gaining in adoption.
There were some areas of the survey that really stood out, however. Such as the small matter of storage, one of our favorite topics! For example, there’s the fact that Ceph continues to be the most popular storage driver, gaining 7 percent since the last survey.

This blog post comes to us from Sayan Saha, Sr. Manager, Product Management, Storage & Data Business, Red Hat. In it, Sayan explores how Red Hat Storage’s server solutions are evolving and adapting to the needs of today’s businesses. Read on!
Red Hat released an update of it’s Storage Server product based on the upstream GlusterFS project in mid-January. It was the most significant update release after the General Availability of Red Hat Storage Server 3.0 in October 2014. Red Hat Storage Server 3.0 update 3 (a.k.a RHSS 3.0.3) delivered a broad set of functionality building upon the major release of the Storage Server 3.0.

The trusty paper shredder in my home office died last week. I’m in the market for a new one. Years ago, when I purchased “Shreddy” (of course, it had a name) after a brief conversation with a random store clerk, choices were few and information scarce. In fact, paper shredders weren’t really considered standard personal office equipment as they are today. Most good shredders were built for offices not homes. Back in the market more than a decade later, it’s clear that the search for a new shredder is going to be trickier than I had imagined.
A paper shredder is a lot like big data.

Digital data has been around for centuries in one form or the other. Commercial tabulating machines have been available since the late 1800’s when they were used for accounting, inventory and population census. Why then do we label today as the Big Data age? What dramatically changed in the last 10-15 years that has the entire IT industry chomping at the bit?
More data? Certainly. But that’s only the tip of the iceberg. There are two big drivers that have contributed to the classic V’s (Volume, Variety, Velocity) of Big Data. The first is the commoditization of computing hardware – servers, storage, sensors, cell phones – basically anything that runs on silicon. The second is the explosion in the number of data authors – both machines and humans.
