Taking a Pulse on Red Hat: Ceph and OpenShift in 2020

It’s been three years since I worked up a software-defined comparison between Red Hat Ceph and Datera, which you can see for reference. That’s 30 years in technology time (one year of human life equals 10 in technology evolution) www.mcafee/activate, so it’s more than time for an update. And www.mcafee.com/activate product key, as you’d expect www.mcafee.com/activate, a sea change has occurred during www.mcafee.com/activate download that period not only for each storage offering, but also in the preeminence of containers and Kubernetes as a foundation of future applications mcafee.com/activate product key.

Setting the Scene

The use of software-defined technologies in storage and other layers of the IT stack has gone mainstream, whereas just over our shoulder www.mcafee.com/activate it was still a niche, early adopter market. Recently, we profiled just how far software-defined technologies in the data plane have come, outgrowing classical hardware-defined arrays by 5X.

Red Hat is also a different entity altogether, now part of IBM with a heightened ability to reach Big Blue customers and beyond. Both Red Hat and Datera continue to see significantly more customer adoption on the www.mcafee/activate back of powerful new feature development powering performance and usability improvements. Datera has experienced increased adoption in the Global 1000 enterprise www.mcafee.com/activate download space www.mcafee.com/activate product key, supporting transactional IO use cases like MySQL databases while Ceph is mainly deployed at service providers and in developer heavy environments.

In the meantime, containers have emerged mcafee.com/activate product key as the central technology of the future, with now half of the Fortune 100 reporting they have rolled out Kubernetes in production. Red Hat has made a big investment in Kubernetes with its OpenShift platform, and similarly Datera has cemented its support for a variety of container orchestrators including OpenShift.

Technology Strides

Ceph has made strides and has IBM’s support www.mcafee.com/activate, which is good news for the software-defined storage market, particularly in the following areas www.mcafee/activate: 

Ease of Rollout, Use and Reporting

Ceph has always been viewed as a powerful engine for the right kind of use cases, but considered to be a bit www.mcafee.com/activate download of a mixed bag on the ease of rollout and ease of use fronts. But our friends at Red Hat have taken many steps www.mcafee/activate to emulate other SDS technologies like VMware vSAN and Datera that excel here. A case in point is Ceph’s Admin dashboard, which provides a graphic view of the overall cluster.

Hyperscale

While making our platform easier to implement and improving our real-time analytics using telemetry data from every node mcafee.com/activate product key remain fixtures on our engineering agenda, our focus in 2019 focused squarely on scaling our deployments www.mcafee.com/activate product key and adding a slate of new media and server vendor options to reduce latency even further www.mcafee.com/activate. On the hardware side, we have improved reporting across all our major supported server www.mcafee/activate platforms including HPE, Fujitsu, Dell, Supermicro, Quanta, and Intel. We also added more predictive features around latency reporting and capacity projections. We are also tracking our customer’s production deployments and are happy to see 70%+ of all write IOs are serviced under 131 µs.

Our Fortune 1000 customers have challenged us to scale to entirely new levels, since our customers typically start with a petabyte of capacity and add from there. To this end, we put ease of rollout on display in multiple forms which are best left to the eye to view rather than discussed.

On The Block: Ceph Bluestore and Datera’s Extent Store

Bluestore was released and as an alternative to using traditional POSIX file systems (filestore) to manage data on each disk. Using existing file systems provides robust data integrity and block management but comes at a great cost to performance and latency as a block storage backend. Bluestore adds a method www.mcafee.com/activate of managing  www.mcafee/activate the block metadata mcafee.com/activate product key on the disk. To improve performance, metadata can be placed on separate media, which is a common technique for traditional file systems as well. In Bluestore’s case, it can be placed  www.mcafee.com/activate product key on an NVDIMM type device or Intel’s new Optane DIMM technology.

The diagram below shows a block diagram of how data www.mcafee.com/activate download, and metadata, flow with the Filestore backend and with the Bluestore backend

Today, we’re releasing an experimental preview of tracking prevention for Microsoft Edge. We features of build microsoft edge as one of the concepts we’re exploring www.mcafee.com/activate product key to offer greater transparency and control over your online data . Microsoft Edge Insiders can www.mcafee/activate now try out tracking mcafee.com/activate product key prevention by enabling the experimental flag on Microsoft Edge preview builds starting with version 77.0.203.0 (today’s Canary channel release).  (Note: Today’s Canary release www.mcafee.com/activate download is not currently www.mcafee.com/activate available for macOS due to a build issues. Tracking prevention will be available in the next update to the Canary channel on macOS.) Tracking prevention is designed to protect you from being tracked by websites that you aren’t accessing directly. Whenever a website is visited, trackers from other sites may save information in the browser ww...

Why businesses need to back up

For almost any business, information is critical: documents, contacts, contracts, correspondence, accounts, and so on. Modern technologies help not only to manage business-critical data  www.mcafee.com/activate product key , but also to lose  www.mcafee/activate  it in the blink of an eye. For most companies, losing access to data means the suspension  www.mcafee.com/activate download  of all business processes  mcafee.com/activate product key , inevitably leading to lost profit, damage to reputation, and recovery costs. Rest assured, there is no shortage  www.mcafee.com/activate  of data loss scenarios out there waiting to happen — and almost none of them has anything to do with the quality of your equipment. Here are just a few. Ransomware An employee might click a malicious file downloaded from the Internet or an attachment in an e-mail sent by cybercriminals. Doing so doesn’t just encrypt data on the local machine; ransomware has a nasty habi...
