Ceph-based cloud block storage service debuts from Atlantic.Net

Atlantic.Net launched a cloud block storage service that uses standard HDDs to keep prices down and an NVMe-based flash cache to boost performance over major disk-based alternatives.

Alantic.Net claims its Secure Block Storage (SBS) performs sequential reads and writes faster than HDD-based block storage from AWS and Microsoft Azure. The hosting provider positions SBS as a choice between HDD and SSD Elastic Block Storage (EBS) options from AWS.

The Atlantic.Net SBS service uses open source, Ceph-based block storage, with a fast nonvolatile memory express SSD cache and inexpensive 7,200 RPM HDDs on the back end. The Ceph system makes three copies of the data, but the customer pays for only one of them, said Marty Puranik, president and CEO of Atlantic.Net.

Atlantic.Net offers 50 GB free for one year from the date the customer signs up for the service and charges 7.9 cents for each additional gigabyte per month. The 50 GB promotional offer is available to current customers through June 15, 2019.

Cloud block storage pricing

On-demand pricing for block storage in the U.S. was 5.5 cents per gigabyte, per month, in the second quarter, according to 451 Research’s Cloud Price Index. The index is based on the cheapest available option for a provider to fulfill a “small basket” specification of two web and two application servers, with 150 GB and 300 GB of attached storage, internet and inter-data center bandwidth for data ingress and egress, and round-the-clock support. The cloud providers generally use HDDs or SSDs for the block storage.

Atlantic.Net’s pricing is competitive against SSD-backed cloud block storage, but less so against HDD-backed block services, according to Deepak Mohan, a research director in IDC’s storage and infrastructure group. Much would depend on the IOPS level the provider can guarantee, he said.

Atlantic.Net offers a service-level agreement for uptime, Puranik said, but not for IOPS — unless the customer contracts for at least a year. The company negotiates IOPS into contracts with those customers and offers discounts based on the block storage quantity and term commitment, he said.

Atlantic.Net’s SBS price and performance level falls between the EBS hard-disk and SSD options, Puranik said. AWS charges 4.5 cents per gigabyte, per month, for its throughput-optimized HDD volumes; it charges 10 cents per gigabyte, per month, for its general-purpose SSD volumes and even more for provisioned IOPS SSD volumes.

“Our service gives better performance than their regular hard drives, and there’s no additional IOPS charge or overages or anything like that. It’s a straight 7.9 cents [per gigabyte] per month,” Puranik said.

Atlantic.Net hosting sites

Founded in 1994, Atlantic.Net started out as a residential internet provider before moving to business-to-business connectivity and web hosting. The company operates out of its own data center in Orlando, Fla., and colocation facilities in New York, Dallas, San Francisco, Toronto and London. Additional options in Ashburn, Va., and Singapore are coming soon, Puranik said.

The SBS service is available only at Atlantic.Net’s Orlando data center, but the company plans to extend it to colocation facilities and offer multisite replication, snapshots and backup, Puranik said.

Atlantic.Net has long offered traditional SAN and NAS storage to customers running applications at its Orlando data center. But, Puranik said, the company wanted a cloud block storage service with a higher level of reliability than the limited-capacity, RAID 10-based local SSD storage Atlantic.Net offered in individual compute servers. The SSDs were overkill in some cases, and customers wanted to scale their storage and move volumes between servers, he said.

Atlantic.Net’s local SSD storage option maxed out at about 2 TB, Puranik said, whereas the SBS service enables as much as 16 TB per volume and eight volumes per server.

Atlantic.Net runs the latest Ceph release with the new BlueStore storage back end that improves performance, supports built-in data compression and provides full checksums to verify data integrity.

Atlantic.Net wrote its own control panel to simplify customers’ deployment of open source Ceph, Puranik said. Users see a slider, choose the size of the block storage volume, create it, name it, mount it and point it at the desired server, he said.

“You wouldn’t know Ceph is running on the back end,” Puranik said.

More storage services planned

SBS is Atlantic.Net’s first dedicated public-cloud-based storage service. Puranik said the company would add an object storage service later this year — also based on Ceph — to target unstructured data. Ceph software supports block-, file- and object-based storage, and it scales out through the addition of commodity server nodes.

Puranik said he expects most customers will use the new SBS service to provide cloud block storage for applications that also run on Atlantic.Net’s cloud compute infrastructure.

“Workloads on the block side are more transactional and compute-driven, and if the compute is close to the block storage service, that would make more sense. So, directionally, Atlantic.Net is probably on the right path. But [it] will face a lot of serious competition from someone like an Amazon,” said Amita Potnis, a research manager with IDC’s storage systems program.

Potnis said Atlantic.Net’s London colocation facility could work to its advantage, because there’s considerable room for growth for a niche provider outside of North America, where Amazon dominates.

What’s new with data protection systems? Everything

How did buying backup hardware get interesting again in this age of software-defined storage and the cloud?

Actually, it’s the software and the cloud that made data protection systems more interesting than they have been in years. The hardware hasn’t changed much since the early 2000s, when disk supplanted tape as the mainstream backup medium. Even the rise of flash in primary storage hasn’t changed the hard disk’s role in data protection systems.

But the game has changed for buying data protection systems, including the role of the hardware. Led by newcomers Cohesity and Rubrik, the targeted uses have expanded. Backup is now just a piece of secondary storage management, and the target includes the cloud as well as an on-premises disk appliance or library.

There’s a good chance your next backup hardware will come with backup software integrated instead of sold separately. That alone changes the buying dynamic. It may simplify the buying and integration processes, but it complicates the decision-making.

How we got here

Rubrik ($292 million in funding) and Cohesity ($160 million) have been the darlings of investors, and each claims it is raking in over $100 million in annual revenue after less than three years in the market. The storage establishment has also taken notice.

Following Cohesity and Rubrik‘s lead, backup vendors Dell EMC and Commvault have gone the integration route with their data protection systems. Backup software leader Veritas Technologies was already selling integrated systems, but is expanding beyond pure backup into data management. Where does that leave software-only vendors such as Veeam Software, which partners with backup hardware vendors but doesn’t sell in integrated appliance to compete with them? That was also Commvault’s situation until it began shipping converged appliances in late 2017.

There are fundamental differences in how vendors integrate software and the cloud on backup targets. That means comparison shopping isn’t always apples to apples.

The last time backup hardware buying went through this much change was during the early days of data deduplication around 2005. Startups such as Data Domain and Avamar (both now a part of Dell EMC) proved the value of shrinking the amount of data that had to be backed up, and the rest of the industry rushed to follow. That change helped make disk the dominant platform for backup.

Now, vendors are scrambling to replicate the integrated concept Rubrik and Cohesity began. Both vendors have roots in hyper-convergence pioneer Nutanix, and they call their technology hyper-converged secondary storage. Other vendors are picking up that term and expect the secondary market to undergo changes similar to what hyper-convergence put primary storage through.

Today’s backup choices

Backup targets are no longer always mere repositories that serve as insurance policies for backed-up data. They can often host platforms that combine backup, archiving, disaster recovery and copy data management. Besides those features, they must connect to the cloud and often manage data across clouds. They replace the need for separate backup software, because they work directly with applications, servers and hypervisors. They can scale up by adding nodes instead of forcing customers to buy a complete new library.

But you may not need that. A large enterprise might want the traditional disk backup library, especially if it already has a lot of critical data on it. And an organization that’s learned to trust its backup software might not want to trash it to use a Cohesity or Rubrik box with their software included. In other words, if you like your backup software, you should keep it. That might mean sticking with a traditional Dell EMC Data Domain-type data protection system as well.

But there are fundamental differences in how vendors integrate software and the cloud on backup targets. That means comparison shopping isn’t always apples to apples.

Choices of data protection systems include complete platforms like Cohesity, Commvault and Rubrik or systems that integrate the vendor’s backup software and don’t need separate media servers like Arcserve, Dell EMC Integrated Data Protection Appliances, Unitrends or Veritas. When buying backup hardware, you must consider factors such as the size and capacity of the system; the way you manage, secure and upgrade it; and how it scales.

With secondary storage use cases blending and factors such as the cloud as a tier, the need to protect software-as-a-service apps through cloud-to-cloud backup and compliance with the European Union’s General Data Protection Regulation becoming a reality, your next backup target will likely be significantly different from your last one.

Pure Storage cloud plan gets warm reception from end users

After hearing the Pure Storage cloud message, customers at the vendor’s Accelerate annual user conference said they were eager to expand their use cases for the vendor’s all-flash storage portfolio.

Pure executives preached simplicity, security and scalability during keynotes at last week’s San Francisco gathering. Customers said they would like to deploy the flash vendor’s revamped products for legacy and emerging AI applications, as well as in public clouds and expanded private clouds.

Charles Giancarlo, CEO of the Mountain View, Calif., company, conjured images of the San Francisco gold rush, likening storage customers to modern-day forty-niners. On average, about half of an organization’s data is never analyzed, because legacy storage infrastructure isn’t equipped to support it, he said.

“We’re moving into the zettabyte era. There’s a huge opportunity to pull that ore out of the ground, and we give you the picks and shovels to do it,” Giancarlo said.

Mining for medical gold

Benjamin Nathan, CIO at the University of California, Los Angeles’ David Geffen School of Medicine, is among those mining for gold in reams of data. Pure Storage FlashBlade scale-out NAS is on his wish list, Nathan said. Although he has no timetable for deploying FlashBlade, Nathan said scale-out NAS is a natural complement to a large FlashArray virtualization cluster.

Pure Storage cloud support for Amazon S3 is attractive, Nathan said, but his Microsoft shop would also like to see Pure integration with Azure.

Nathan became a Pure customer when serving in IT leadership jobs at Cornell University’s Weill Cornell Medical College in New York City before heading west. At UCLA, Nathan said he installed Pure Storage FlashArray to replace roughly 500 physical servers and provided centralized shared storage for more than two dozen IT teams.

“The thing that interests me about FlashBlade, beyond just the performance and scalability, is you can use it to provide storage-like workspaces from Amazon S3 and, hopefully, eventually, Azure,” he said. “I want to seamlessly be able to incorporate our on-premises and cloud storage in one offering that I can manage on the back end.”

When uptime matters

Robert Green, CTO of virtual desktop infrastructure specialist Dizzion, said he was initially skeptical of Pure’s claims it could scale performance to handle any workload. Dizzion, based in Denver, provides desktop as a service to organizations that need continuous uptime.

“I told them, ‘OK, we’ll throw our most challenging workloads at it,'” Green said. “We have one customer that always red-lines our storage, and they can’t have any downtime. I put that workload on the Pure, and it didn’t miss a beat.”

Dizzion’s Pure Storage cloud consists of dense “pods” of compute and storage, Green said. Each pod has 42 server nodes atop 6U of FlashArray storage and can support 3,000 desktops. Dizzion has scaled to nine pods.

“It cost us less to buy the Pure Storage than to keep building our own servers and flash-based storage devices every year,” Green said.

Some Pure Storage cloud customers — such as Workday — are moving slowly to adopt a multi-cloud architecture. Workday provides financial services and human resources software via its private cloud.

Workday replicates mission-critical data among its own data centers, using the cloud selectively, said Job Simon, the Pleasanton, Calif., company’s vice president of IT strategy and architecture.

Workday deploys a Pure Storage cloud environment on FlashArray//M systems to send fast reads and writes in memory to disk. Pure Storage is enormously helpful in managing the throughput for mixed workloads, Simon said.

Data reduction results

Frost Bank, based in San Antonio, switched to Pure Storage after years as a Hitachi Vantara customer. As a financial services firm, Frost Bank avoids placing data beyond its internal firewall, said Dan King, Frost’s vice president of IT operations.

“One of the interesting things I heard during this conference is that people still think of Pure as an array for point-in-time use cases, and that’s not how we use it at all,” King said. “We use Pure to replace entire Hitachi VSPs [Virtual Storage Platforms]. We run 90% of our workloads on the Pure.”

King said he is most impressed by the high data reduction Pure delivers to his highly virtualized storage.

“We had about 150 TB of VMware, but after data deduplication and compression, that equaled 12 TB of actual storage,” he said. “That’s amazing. I would have bought and paid for all of that [capacity] with any other vendor.”

Pure Storage software tooled up for containers, OpenShift, VMware

Pure Storage software news received less attention than its nonvolatile-memory-express-enabled FlashArray last week at the company’s Pure Accelerate user conference, but the new features did cover a lot of ground.

The expanded Pure Storage software includes integrated cloud synchronization with VMware, Red Hat OpenShift and Linux-based Docker containers. Pure also introduced the Evergreen Storage Service (ES2), a Pure-managed private cloud with utility pricing for on-premises bare-metal consumption.

Software features tackle virtualization woes

A core tenet in Pure Storage software development is to add data services while keeping things simple for customers, said Sandeep Singh, Pure’s senior director of cloud and new stack solutions marketing.

“This is all part of our strategy to help you build a data-centric architecture to transition workloads faster and with less effort to multiple cloud environments,” Singh said.

Pure Storage wrote its own software-defined stack for VMware SDDC. The VMware-certified code integrates with VMware Virtual Volumes and the full vRealize suite. Authorized users provision data storage to individual virtual machines via policy-based service catalogs. The underlying storage is Pure Storage FlashBlade in place of VMware Virtual SAN.

Pure also launched software tools to address the challenges of persistent Docker storage application containers. Customers can get a reference design for implementing platform as a service using Pure Storage FlashArray and Red Hat OpenShift.

Additional Pure Storage software can help optimize large-scale Docker deployments with Kubernetes. The Pure Service Orchestrator is intended to speed stateless and stateful containers via the Pure stack.

“You have a big pool of storage across many FlashArray and FlashBlade [machines] and can allow the container environment to provision storage automatically,” said Matt Kixmoeller, Pure’s vice president of strategy.

Pure multi-cloud approach includes on-premises managed service

The all-flash array vendor also added data protection software. PureSnap enables snapshot replication from Pure Storage flash to any NFS target. CloudSnap replication to Amazon Web Services’ S3 is on the product roadmap for this year, Singh said.

ES2 builds on the Pure Storage Evergreen Storage subscription that lets customers buy storage upfront and receive nondisruptive upgrades. With ES2, customers select capacity and performance requirements. Pure Storage selects the type and number of hardware arrays needed and deploys them at a customer’s site.

Kixmoeller said ES2 gives enterprises a chance to build scalable capacity while maintaining control of data.

Rob Green, CTO of desktop-as-a-service firm Dizzion, said he expects to deploy ES2 as a private cloud for back up and testing on an existing 42-node Pure Storage environment.

“I think ES2 will be huge for us. I don’t trust the big box clouds to protect my data. Having Pure on premises on a subscription? I’m geeked out about that,” Green said.

For DevOps organizations, the vendor released Pure Storage software development kits for full stack automation with open source configuration engines, including Ansible, Puppet, Python and SaltStack.
