Those of you familiar with Red Hat Storage might remember that our mission is to offer, with our partners, a unified, open, software-defined storage portfolio for next-generation workloads that helps accelerate the transition to modern IT infrastructures. The recent news with SanDisk affirms our commitment to this mission. Our newly found friendship with one of the global leaders in flash storage is predicated upon extending Red Hat Ceph Storage to even further heights, and it demonstrates how open source software benefits not only from the innovation of those in the community but also from an open commercial ecosystem that traditional solutions are hard-pressed to duplicate.

Joining forces with another product giant

On the heels of the Red Hat Ceph Storage 1.3.2 point release–one stealthily promoted yet proudly delivered with management, security, and performance upgrades–we’ve formalized a strategic alliance with SanDisk aimed at supporting the scalability and performance needs of enterprise customers. The combined solution, which incorporates Red Hat Ceph Storage and Red Hat Enterprise Linux with the SanDisk InfiniFlash™ system, has been optimized and tested to offer high density and peak performance at scale.

Taking aim at joint customer pain points

The motivation between such an alliance stems from a common understanding of what our customers need and how satisfying these needs is essential for next-generation storage in a software-defined datacenter. We’re talking about applications requiring high performance and low latency, like demanding OpenStack cloud platforms, large-scale Splunk log analytics, high-speed messaging servers, and read-intensive apps that process large amounts of data. We’re talking about customers deploying multiple storage solutions for different classes of applications at the risk of over-provisioning hard disk drives (HDDs) to meet SLAs and exceeding their capacity, space, power, and cooling capabilities. We’re talking about increasingly scrutinized budgets, cost containment, and the pressure to achieve economies of scale in datacenter operations.

One and one equals three!

Red Hat and SanDisk knew that our respective solutions delivered bona fide business benefits for storage customers, but together, we had the best of both worlds. We simply needed to document the configurations, certify compatibility, and provide basic training on our respective products to SanDisk Global Customer Care and Red Hat Global Support Services.

The result is nothing short of “performance that scales” in an integrated, single-platform solution. Red Hat Ceph Storage and SanDisk’s InfiniFlash System offer petabyte-scale capacity, high density, and performance, which can yield powerful cost-economies for our joint customers with big data storage requirements. The combination delivers the performance of an all-flash array with the economics of an HDD-based system and the scalability and versatility of a Red Hat Ceph Storage software-defined storage platform. Our customers can apply it not only to integrated OpenStack environments but a wide array of workloads in medium to large deployments.

We encourage customers to seek more information about this offering from their Red Hat or SanDisk sales reps and to consider how the combined benefits of Ceph and flash storage might help their organizations. At the same time, let’s give a shout out to our friends at SanDisk for joining us as part of the Red Hat Storage Nation and setting the bar even higher for next-generation, scale-out storage.

Enterprising businesses get to Red Hat Storage Days!

By E.G. Nadhan, Chief Technology Strategist, Red Hat

As businesses are increasingly being asked to cope with burgeoning amounts of valuable data, there’s a data explosion in the enterprise. This explosion fuels the need for a new approach to storage, which is the underlying theme of Mark Thiele’s article, 400 million new servers needed by 2020 — Think different or lose. “You aren’t ready to scale the way you’re going to need to scale,” he contends, noting that data sources are projected to reach 30 to 50 million by 2020. In his article, Are 18-month org charts and constant training the new reality of IT?, Curt Carver agrees, saying, “To plan for an IT future, you’ve got to be agile….”

So the drumbeat is growing louder: Digital enterprises need storage solutions that are agile and continuously evolving to accommodate dynamically changing requirements.

What’s an enterprising business to do?

To meet contemporary storage challenges head on, digital enterprises of the future should embrace open source and all it enables. To that end, Red Hat GM for Cloud Product Strategy, Bryan Che, penned an article titled, Open source is programming the digital future, noting that innovative companies like Uber and Facebook have embraced a digital approach to help ensure their long-term viability. Che’s article highlights the role of open source in this evolution as it contributes to the creation of new categories of functionality across enabling technologies.

Latest release of Red Hat Gluster Storage enhanced with container support, file-based auto tiering, writable snapshots, and more

By Alok Srivastava, Senior Product Manager, Red Hat Gluster Storage and Data, Red Hat

Red Hat Gluster Storage 3.1.2 became generally available today, adding such key functionality as containerization and file-based auto tiering to its already feature-rich base. For detailed information on all the latest Red Hat Gluster Storage features and enhancements, see the documentation and read on here. For my interview on the topic, watch our video below.

 

 

Key feature enhancements

 

Red Hat Gluster Storage image on Red Hat’s container registry for persistent file storage for containerized applications

Persistent file-based storage from containerized Red Hat Gluster Storage can be consumed by containerized applications over the network (see following figure). You can quickly bring up a Red Hat Gluster Storage container in a Red Hat Atomic Host or on Red Hat Enterprise Linux by simply pulling a Red Hat Gluster Storage image from Red Hat’s container registry.

 

RHGS 3.1.2 (1)

 

File-based auto tiering to leverage innovation in flash and HDD design

The file-based auto tiering feature of Red Hat Gluster Storage 3.1.2, initially available only in tech preview and supported on Red Hat Enterprise Linux 7 based on Red Hat Gluster Storage, places frequently accessed or “hot” data on fast media (e.g., flash, SSDs) and seldom-accessed or “cold” data on higher capacity yet slower-spinning media (see following figure).

 

RHGS 3.1.2 (2)

 

Tiering combines SSDs and HDDs to enable intelligent data placement and thereby boost performance and cost efficiencies. For example, a new or an existing volume may be distributed (erasure coded) on HDDs and the hot tier could be distributed on SSDs. The “attach” operation of tiering, transparent to applications, converts existing volumes into a cold tier. Together, the combination is one tiered volume.

 

Writable snapshots with shared backend LVM store

This release of Red Hat Gluster Storage supports writable snapshots–clones of snapshotted volumes with read/write permissions. Until today, only thin, LVM-based, read-only snapshots were available in the product. The writable clones, which are space efficient and instantly created, share the backend LVM store with their parent snapshots (see following figure).

 

RHGS 3.1.2 (3)

 

Other feature enhancements

 

Bit rot detection status

The bit rot detection functionality in Red Hat Gluster Storage periodically scans all data bricks in the product, compares checksums, and identifies and sometimes proactively fixes corrupted files. This release augments this feature so that you can identify corrupted files easily and take any necessary corrective action.

Faster SMB access

SMB shares back-ended by Red Hat Gluster Storage now perform better for streaming workloads. With this release, asynchronous IO from Samba to Gluster is supported and the relevant option is enabled by default in smb.conf. We have seen up to 100% performance increase from the previous release in our performance labs!

Offline console installation

Offline installation of the Red Hat Gluster Storage console is now enabled by offering an OVA image. You can now import RHGS-C OVA image to Red Hat Enterprise Virtualization Manager and install the console s/w on virtual machines.
