Container-native storage, faster self-healing, sharding, and more

It’s a great time to be a storage aficionado! Last week, we announced Red Hat Ceph Storage 2. Today, we’re thrilled to announce the general availability of Red Hat Gluster Storage 3.1.3.

Building on momentum

Red Hat Gluster Storage has enjoyed strong momentum in terms of customer success and community growth. We’ve added a number of enterprise-class features over the past 3 to 4 years that have significantly enhanced performance, reliability, durability, and security.

Software-defined storage offers the best of both worlds—the flexibility to grow storage incrementally and reuse existing industry-standard hardware, while also taking advantage of the latest innovation in storage controller software and hardware components. For more on Red Hat Gluster Storage 3.1.3 features, check out the following video.

Feature-packed release

The 3.1.3 release of Red Hat Gluster Storage includes a number of feature enhancements that enable greater performance, reliability, and faster self-healing, including deep integration of Red Hat Gluster Storage with other Red Hat products.

Persistent storage for containers

You may have already seen our blog post from earlier today on container-native storage for OpenShift Container Platform. Earlier this year, we announced a containerized image of Red Hat Gluster Storage. This release moves a step further and enables converged storage containers that can co-reside with application containers on the same host. Shared resources between application and storage help in overall TCO reduction. Containers are deployed and provisioned using an enhanced Heketi module.

Container-native storage provides storage services to the application containers by pooling and exposing storage from either local hosts or direct-attached storage.

Multi-threaded self-heal

All at once or one at a time? While the debate between single- and multi-threaded approach is never ending, Red Hat Gluster Storage self-heal certainly does better for some workloads when it is parallelized. This release of Red Hat Gluster Storage allows you to perform self-heal in parallel. Multi-threaded self-heal will be most useful with a large number of small files (e.g., sharded VM images). Facebook is the primary contributor to multi-threaded self-heal in the Gluster community.

Sharding

Sharding refers to breaking a large file into tinier chunks. Sharding splits large virtual machine (VM) image files into small blocks of configurable size. This results in faster self-healing with reduction in CPU usage, which helps the hyperconvergence of Red Hat Gluster Storage with Red Hat Enterprise Virtualization and live VM use case.

Geo-replication feature of Red Hat Gluster Storage is also sharding aware for these two use cases so that only required shards/ fragments are replicated.

Integration with VSS

We heard you! You need not call up your storage administrator if you are a Windows user and need to browse through the previous version of any file/folder. Red Hat Gluster Storage is now integrated with Volume Shadow Copy Service (VSS) of Microsoft Windows. Red Hat Gluster Storage supports the viewing and accessing of snapshots.

RHGS 3.1.3-3

SMB Multichannel

Have more network adapters? Get better SMB performance! SMB Multichannel is a feature of SMB 3.0 protocol that increases the network performance and availability of Red Hat Gluster Storage servers. SMB Multichannel allows use of multiple network connections simultaneously and provides increased throughput along with network fault tolerance. SMB Multichannel is provided as a technical preview feature with Red Hat Gluster Storage 3.1.3, and we intend to fully support it soon.

Easy installation of hyperconverged setup

We’ve ensured that the installation of the hyperconverged setup of Red Hat Gluster Storage and Red Hat Enterprise Virtualization is easy enough for you. The Ansible-based gdeploy tool is enhanced for the automated installation of hyperconverged setups.

Kilo refresh for Gluster Swift

We’ve refreshed Gluster Swift to support OpenStack Kilo for RHEL 7-based Red Hat Gluster Storage. RHEL 6-based Red Hat Gluster Storage continues to support Openstack Icehouse.

Scheduling of geo-replication

Periodic scheduling of geo-replication allows administrators to synchronize data between clusters during non-peak hours. We have detailed performance and sizing guides available later this year, with prescriptive guidance to tweak the right price/performance mix for your workloads.

RHGS 3.1.3-4

Red Hat Gluster Storage sets the storage agenda. Again. This time with new container-native storage.

Earlier today, you may have read the news about container-native storage for OpenShift Container Platform, which helps developers manage storage just as easily as applications. As the name suggests, storage and applications are served out of containers running on the same server. Red Hat Gluster Storage runs in a container inside OpenShift, just like another application, but instead it serves storage. This helps lower costs and increase control and flexibility. Even better, it enables customers to move applications between platforms (on-premise, virtual, cloud, containers) without needing to rewrite code to deal with different storage environments.

What’s the big deal?

Containers are the next big thing. There’s a good chance you’re thinking about, planning, or already transitioning your applications to containers. While the container revolution started primarily with stateless applications, the reality is that most enterprise applications running in containers need a persistent storage layer to store application data, state, and configuration, all of which need to live beyond the life of a container. Our engineers have delivered a continuum of innovation by containerizing Red Hat Gluster Storage itself, and also leveraging API-driven volume allocation to help easily manage and provision storage for containers. Simply put, Red Hat Gluster Storage solves the persistent storage challenge for containers.

Why Red Hat?

Today’s storage news is aligned to the announcement outlining Red Hat’s strategy to offer the OpenShift platform from development to cloud platforms. Container-native storage strengthens the Red Hat value proposition for containers, while also increasing the appeal of Red Hat solutions to developers. In the words of Scott Sinclair, Senior Storage Analyst at ESG: “Any integration of storage into the container host and application development platform goes a long way to alleviating resistance in container adoption.”

In addition, this capability comes backed by Red Hat’s world-class support, offering a single point of support for customers looking for a comprehensive solution for their container environments.

To containers and beyond!

Red Hat Gluster Storage has made huge leaps in terms of adding enterprise-grade storage features over the last 3 to 4 years. Significant enhancements to scalability, reliability, performance, and security features have helped it surpass traditional storage solutions in terms of price/performance. Now, all this enterprise-class functionality is available for containerized applications.

Red Hat Gluster Storage is flexible, it’s easy to set up and use, and it’s one of the few storage solutions in the marketplace that can span classic, mode 1 customers to all-in, mode 2 customers and everything in between. Follow our story at Red Hat Summit this week.

The milestone of Red Hat Ceph Storage 2

By Daniel Gilfix, Red Hat Storage

This week’s announcement of Red Hat Ceph Storage 2 marks the most significant release of the cloud-native, software-defined storage product since the acquisition of Inktank by Red Hat in 2014. It represents an important milestone, not only in terms of the company’s steadfast commitment to storage but also from the perspective of preparing open source customers for the highly coveted software-defined datacenter.

Why storage matters

We work in an era where storage is often taken for granted, under-glamorized for the role it serves, and yet increasingly essential, often indispensable, to solutions spanning physical, virtual, private cloud, container, and public cloud environments. Nevertheless, in recent studies commissioned by Red Hat, Vanson Bourne Ltd reports that 71% of IT decision makers fear their organizations’ storage solutions won’t be able to handle next-generation workloads, while 451 Research indicates that 57% already have or are moving to software-defined datacenters this year. As most loyal Ceph followers know, this is precisely why folks are so excited about the launch of our new product.

What’s new in 2

While Red Hat Ceph Storage has distinguished itself as a unified storage platform that’s overwhelmingly preferred for OpenStack, for years Ceph has actually fulfilled this role with folks like service providers and the telco community as an object store proven at scale. Red Hat Ceph Storage 2 adds innovation resulting in a far more robust object storage solution for a wide variety of use cases aimed at the enterprise, like active archive, big data, and media content hosting. Customers also receive an easier-to-use product and life-cycle management by virtue of the integrated Red Hat Storage Console 2.

Object storage enhancements

Ceph’s object storage interface, RGW, has greatly improved. RGW geo-clusters with single namespace allows local communications with local clusters with “eventually consistent” synchronization between them. RBD mirroring enables multi-site replication for disaster recovery and archival. Support for Active Directory, LDAP, and Keystone v3 authentication systems expands security options. And improved S3 and Swift protocol API support–such as AWS v4 client signatures, bulk delete, and object versioning–strengthens compatibility with AWS and OpenStack, respectively.

Sneak peek

In addition, there are three sets of functionality in Tech Preview for early customer exposure:

  • CephFS, the POSIX-compliant file system that uses a Ceph storage cluster to store data in accordance with the OpenStack Manila service
  • An NFS-to-S3 gateway for import and export of object data
  • BlueStore, a new storage media backend that we expect to lead to 2-3X performance improvements for the entire product

Bottom line

All these features are instrumental to empowering Ceph to keep pace with the ever-growing demands of its spirited user base and to handle multi-petabyte workloads with the grace and efficiency that enterprise customers need for software-defined datacenters. On the surface, they might not appear especially sexy, but for cloud builders and IT decision makers of all sorts, many of whom are already in the loyal Ceph community, they are a breath of fresh air to an otherwise stifled march toward storage infrastructure agility.

See you at Summit

If you’re coming to Red Hat Summit at the Moscone Center in San Francisco between June 27-30, please stop by the Red Hat Storage booth (#31-32) or the partner pavilion (#529), where a cross-sample of Ceph partners are demonstrating the elements of our extended ecosystem.
