Red Hat not likely to combine Ceph, Gluster into single product

Red Hat Storage

One petabyte-scale storage customer traveled to this week’s Red Hat Summit in Boston with dreams of Ceph and Gluster merging into a single product. He hoped Red Hat would take the best pieces of each and “slam them together.” He suggested the vendor could dub the new creation Red Hat Storage, Red Hat Software-Defined Storage or Red Hat Scalable Storage, or “come up with a fun new name.”

“I was waiting for it, and it just didn’t happen,” said Nicholas Gerasimatos, director of engineering at Fair Isaac Corp. (FICO).

And it isn’t likely to happen soon, if ever, according to the heads of product management for Red Hat’s commercially supported versions of open source Ceph and Gluster software.

“They’re very different, and the way we see Ceph and Gluster is that they’re targeted at different parts of the market,” said Neil Levine, the Red Hat director of product management who laid out Ceph’s long-term roadmap during a conference session this week. “Ceph is Fortune 500, ‘I’m building a huge Amazon-style cloud.’ Gluster is not mid-market, but it’s certainly for customers that have a problem ‘that I need to fix and I don’t have months to set this up; I’ve got like a week.’ ”

Levine said the reason the conversation crops up about combining Ceph and Gluster is “mainly because customers want a file system, which Gluster provides, but then they like the distributed smarts underneath Ceph.”

“It’s something that I don’t think we’re likely to do,” Levine said. “Customers can do it, but it’s not a supported configuration that we’re going to recommend or push. I think if you want our file system, you should use Gluster, and trying to put Ceph underneath it, you’re just giving yourself an operational headache and potentially expense if you’re going to buy those products from us as well.”

Separate communities develop the open source Ceph and GlusterFS projects. Ceph’s community is working on a file system, but CephFS is generally regarded as not ready for enterprise prime time yet. In the meantime, Ceph sees use for block and object storage. Gluster offers file and object capabilities.

“Instead of trying to combine the two products, we will come up with a control plane that makes these two products look consistent,” said Sayan Saha, head of product management for Red Hat Gluster Storage. “Our eventual goal is actually to get rid of the whole concept of Ceph and Gluster.”

Saha said the new control plane could provision, manage, monitor and tune Gluster and Ceph in the same way, “where all you care about is data services for your workloads as opposed to caring about where it is coming from.” Red Hat demonstrated the unified storage management technology at its booth in the conference’s exhibit hall. The company wrote the controller software in the last six or seven months, according to Saha.

“You want virtual block storage. You want file storage. Or, you want object storage. You will be able to come to that controller and request that, and it will be served out to you,” Saha said. “If you choose that you want to do block storage, it will give you Ceph, and then you go to the Ceph provisioning. If you say file, it will say Gluster.”

Red Hat currently recommends Ceph or Gluster based on the workloads the customers intend to run, but there can be overlap between the two products. For instance, Gerasimatos said when Red Hat visited FICO, one group told them to use Gluster, and the other group said Ceph. FICO engineers ultimately chose Ceph and decided to run the free, open source version of Gluster on top of Red Hat Ceph in cases where they needed a file system.

Craig Hadix, a data center architect for a global systems integrator, said Red Hat’s two-product storage strategy can be confusing. He said he would be surprised if Gluster is still around in a year. He thinks it would be smart to “take the feature set that Gluster provides and integrate it into one storage product that has Ceph and Gluster features.”

But, combining the source code from two distinct software applications can be a bear of a project. Just ask NetApp. The company spent years trying to merge the scale-out NAS software from its Spinnaker Networks acquisition with its Data OnTap operating system.

“NetApp does aggregation for eight years,” Saha said. “There’s no product.”

PernixData plans platform proliferation

Dave Raffo Dave Raffo Profile: Dave Raffo

PernixData executives this week disclosed three coming additions to its core FVP software, which clusters server flash and RAM to accelerate I/O and reduce latency.

PernixData claims around 400 customers use FVP to serve read and write I/O requests inside VMware hosts.

Founder and CTO Satyam Vaghani previewed the new products for storage bloggers this week at a Tech Field Day event, and vice president of marketing Jeff Aaron filled in details in a subsequent interview.

FVP Freedom, PernixData Architect and PermixData Cloud are expected to officially launch around the time of VMWorld in August, along with FVP 3.0. The additions will enhance FVP, although Freedom and Architect can be used independently.

Freedom is a free version of PernixData’s acceleration software that pools RAM but not flash resources. Freedom will be available on an unlimited number of hosts and VMs, and in clusters up to 126 GB of memory. Support will be limited to the PernixData community.

“We took read acceleration and said ‘We’re going to make that free,’” Aaron said. “We know once people feel it and touch it, they’ll want more [and upgrade to a standard FVP license.].”

PernixData Cloud is an analytics program that provides insights into customers’ environment.

It collects metadata from all customers using FVP – and in the future Freedom – and shares high-level results with other users to give them an idea of how their environment stacks up.

“We collect data and feed it back to you,” Vaghani said. “Our vision is to share the entire planet’s metadata with each other. You want to know if you’re running 4,000 hosts and 40,000 virtual machines, what other people who are running 4k hosts and 40,000 virtual machines are doing. Before this, here was no good data to share and no good way to share it.”

Or, as Aaron put it, “it’s like we’re crowd-sourcing” to provide information that analysts deliver in reports.

The goal of Architect is to monitor virtual servers and storage devices, and help optimize applications running on them. It does predictive analysis to detect when problems could occur, but can also be set to take prescriptive action to fix problems.

“If a VM goes bad, you get a red blinking light that tells you what went wrong,” Aaron said. “There are tools for monitoring servers and tools for monitoring storage, but nobody ties them together like this. It suggests remediation and can be automated to do the remediation.”

Aaron said while Architecture can run without FVP, it has great insight into a user’s environment and can fix more problems if used with FVP.

The next version of FVP will include support for VMware vSphere 6 and VVOLs, along with a new user interface and connectivity with Architect. FVP’s VVOL support should be interesting, considering Vaghani helped write the original VVOLs specs in his previous job as VMware’s principal engineer and Storage CTO.

Other items on the PernixData roadmap include support for Microsoft Hyper-V and KVM hypervisors (FVP only supports VMware today) and containers. But those additions are not expected in the next version of FVP.

NetApp’s Kurian ‘not constrained’ from making changes … or not making them

Dave Raffo Dave Raffo Profile: Dave Raffo

New NetApp CEO George Kurian today said he has a free hand to make any changes he believes are necessary at the company while giving no indication that any sweeping changes are coming.

Kurian, who replaced Tom Georgens as CEO on June 1, discussed his vision for the company during a webcast hosted by UBS IT hardware analyst Steve Milunovich. Customers, partners and investors looking for the company to go in a new direction will likely be disappointed by Kurian’s insistence that he is looking to execute on the plan put in place before his promotion to CEO.

Although new chairman Mike Nevens said there is a CEO search underway, Kurian is not listed as an interim CEO and he said he is free to make the moves he wants.

“I am operating as CEO of the company and I do not feel constrained in any manner as far as making changes to necessitate success,” he said.

NetApp revenue has declined for the past two years and the company forecasts little or no growth this year. But if Kurian plans any changes, he kept them to himself today while taking questions from Milunovich and others on the call. He said NetApp will continue to embrace hybrid clouds, Data OnTap storage software and three all-flash array platforms.

When asked why the CEO change was made and what he will do different than Georgens, Kurian said he would “translate the strategy we have into more vigorous execution.”

Kurian played down suggestions from several questioners that NetApp is too focused on its core Data OnTap software, and that it needed to diversity its products. He said the vendor has moved into hybrid cloud storage, cloud backup, all-flash arrays, object storage and hyper-convergence (through a partnership with VMware) in recent years. He added that he doesn’t think NetApp needs to add more products through acquisitions.

He said it was not new to have competition from smaller companies such as Nutanix, Pure Storage and Nimble Storage competing with NetApp as well as large rivals such as EMC and Hewlett-Packard. “We’ve had multiple competitors before. We always worry about competition and how to differentiate ourselves,” he said.

Kurian also proclaimed NetApp the leader in software-defined storage, but said that does not mean it will be releasing software-only versions of its main storage platforms. “The value of software-defined storage is as a consistent way to manage data across a diverse set of hardware,” he said. “You can have the same data management landscape across extreme performance and extreme capacity configurations, remote offices and the hybrid cloud.”

Kurian was grilled on NetApp’s all-flash strategy, which includes all-SSD versions of its FAS enterprise and EF Series high performance computing arrays, and a built-from-the-ground up FlashRay platform that is not yet generally available. Kurian defended that strategy, although NetApp all-flash sales lag those of EMC’s XtremIO, Pure’s FlashArray and IBM’s Flash System.

“If you believe flash is transformative, it will be used in a broad range of use cases,” he said. “One of those is where people want mature data services, enterprise-grade resiliency and performance. OnTap allows customers to have no-compromise use cases. There will also always be customer that wants extreme performance and the fastest thing in the world. That’s the EF Series. For customers who want a few features but the full capability of a large data center system, that’s where we target FlashRay.”

Kurian was also asked about NetApp’s EVO: RAIL hyper-converged product that it will sell in partnership with VMware. He said hyper-convergence is “a carbon copy of all other parts of the virtualization landscape” and customers will want to seamlessly move workloads and have consistent data protection.

Kurian said he has worked with new Cisco CEO Chuck Robbins during his time at Cisco and during his four years at NetApp, and expects the FlexPod reference architecture partnership between the two vendors to remain strong.

As for what is probably NetApp’s most immediate product concern — customers struggling to upgrade to clustered Data OnTap from the vendor’s standard OnTap — Kurian said the early adopters of the clustered product have been new customers or those who only have one workload to migrate. NetApp’s IT team required months to complete its upgrade to clustered OnTap, but Kurian said that was because the storage migration was done along with other projects, including Microsoft Windows and SQL Server upgrades.

Backup appliance revenue grows, but leader EMC’s shrinks

Dave Raffo Dave Raffo Profile: Dave Raffo

EMC remains the leader in backup appliance sales but its grip on the market is loosening.

While backup appliance revenue increased seven percent year-over-year in the first quarter of this year, EMC revenue fueled mainly by Data Domain dropped more than five percent, according to the latest IDC tracker numbers. Second-place Symantec shaved more than 10 percentage points off EMC’s market share lead following 46 percent growth in the quarter.

EMC still has most of the market share, but its share slipped from 59.2 percent in the first quarter of 2014 to 52.4 percent this year. Symantec jumped from 13.5 percent share last year to 18.5 percent this year after strong growth by its NetBackup appliances. EMC revenue came in a $377 million compared to Symantec’s $133 million as EMC fell below 60 percent share for the first time in a year.

The next five vendors behind Symantec also increased revenue from the previous year. IBM increased seven percent to $37.5 million while its share remained at 5.2 percent. Hewlett-Packard followed at $32.5 million after growing three percent, but its market share slipped from 4.7 percent to 4.5 percent. IDC lists IBM and HP in a statistical tie because their share was within one percent of each other.

Barracuda and Quantum each had a bigger percentage increase than Symantec. Barracuda grew 65 percent year-over-year to $25.2 million, and its market share increased from 2.3 percent to 3.5 percent. Quantum grew 58 percent to $24 million with share increasing from 2.3 percent to 3.5 percent. Dell, in a statistical tie for fifth with Barracuda and Quantum, increased 28 percent to $18.3 million and its share rose from 2.1 percent to 2.5 percent.

All other vendors combined for 10 percent of the market after slipping one percent in revenue from last year. The total market hit $719 million for the quarter and 647 PB shipped for an increase of 32 percent over 2014.

VMware gives EVO:RAIL hardware partners more options

Dave Raffo Dave Raffo Profile: Dave Raffo

VMware is giving its hardware partners more options for building EVO:RAIL hyper-converged appliances.

Dell, EMC, Hewlett-Packard, Hitachi Data Systems, and Supermicro are among the hardware vendors who sell EVO:RAIL appliances packaged with VMware’s Virtual SAN (VSAN) hyper-convergence application.

VMware’s new configuration options can support approximately 1,600 generic virtual machines (VMs) and 2,400 virtual desktops in an eight-appliance (32-node) cluster, up from 800 generic VMs and 2,000 virtual desktops in the previously supported configuration.

EVO:RAIL hardware options now include dual six-, eight-, 10- or 12-core Intel Haswell or Ivy Bridge CPUs per node, 128 GB to 512 GB of memory per node and two capacity options. The first capacity option is one 400 GB solid state drive (SSD0 with three 1.2 TB hard disk drives per node for 1.6 TB of raw SSD capacity and 14.4 TB of total hard disk capacity per appliance. The second option is one 800 GB SSD and five 1.5 TB hard disk drives per node for 3.2 TB of raw SSD and 24 TB of hard disk capacity per appliance.

The original EVO:RAIL configuration set last August was for dual six-core Haswell or IVY Bridge CPUs, 192 GB of memory and the 14.4 TB capacity option.

Mornay van der Walt, vice president, EVO:RAIL Group, VMware, said VMware planned to make these additional options available later this year but moved them up at its partners’ request. Some partners have already started using their own configurations. For example, EMC’s Vspex Blue EVO: RAIL product launched in February with 126 GB and 192 GB memory options.

“As customers are finding their own swim lanes, we’re getting demand for more configuration options,” van der Walt said. “This was on our roadmap, but given the demand we said, ‘Let’s roll this forward.’”

VMware has yet to make VSAN 6 – the latest version of VSAN – available to EVO:RAIL partners. EVO:RAIL appliances still run VSAN 1.5, with VSAN 6 expected to show up on them in the second half of 2015.

Van der Walt said VMware has sold more than 1,200 VSAN licenses since it launched in 2014.

Disk storage increases over Q1 2014, but networked storage declines

Dave Raffo Dave Raffo Profile: Dave Raffo

Disk storage revenue grew 6.8 percent during the first quarter of 2015, with server-based and hyperscale storage picking up the slack for SAN and NAS sales according to IDC’s latest storage tracker numbers.

External storage – SAN and NAS – dropped 0.6 percent from the first quarter of 2014. It slipped from $5.64 billion to $5.61 billion. That compares to overall disk sales that jumped from $8.21 billion in the first quarter of 2014 to $8.77 billion in the first quarter this year. Total capacity shipments increased 41.1% year over year to 28.3 exabytes during the quarter.

“Following a busy end-of-year spending environment, the enterprise storage market fell back into what has become a familiar market pattern,” IDC storage research director Eric Sheppard said in a statement. “Spending on traditional external arrays fell during the quarter while demand for server-based storage and hyperscale infrastructure was up strongly during the quarter.”

Server-based storage includes hyper-converged and direct attached storage, while hyperscale infrastructure consists of large-scale web storage.

From a vendor perspective, Heweltt-Packard (HP), Dell and Hitachi Data Systems (HDS) increased year-over-year while sales from EMC, NetApp and IBM decreased. Original design manufacturers (ODM’s) selling directly to hyperscale data center customers accounted for 12.6 percent of global spending and the “others” category made up 30.5 percent of disk storage sales.

In the overall disk market, EMC held on to the No. 1 vendor spot despite a 6.7 percent decline to $1.51 billion for the quarter. EMC’s market share dropped from 20 percent to 17.4 percent. No. 2 HP increased 19.3 percent to $1.28 billion and increased market share from 13.1 percent to 14.6 percent. Dell moved past NetApp into third, growing six percent to $897 million for 10.2 percent share. NetApp revenue fell 10.5 percent to $765 million and it slipped from 10.4 percent market share to 8.7 percent. Fifth-place IBM’s revenue declined 29.3 percent to $525 million and went from nine percent share to six percent.

EMC and NetApp remained the top external disk vendors – all of their revenues are in that category – with EMC at 27.3 percent share and NetApp at 13.6 percent. HP ($512 million) and HDS ($507) are in a virtual tie for third with HP holding 9.1 percent share and HDS nine percent. IBM placed fifth with $424 million, falling 12.8 percent and dropping from 8.8 percent share to 7.7 percent. Dell was sixth with $395.1 million, an increase of 2.1 percent over 2014 for seven percent share.

HDS fully digests Pentaho

Dave Raffo Dave Raffo Profile: Dave Raffo
Data Analytics, Hitachi Data Systems, Internet of Things

Hitachi Data Systems (HDS) closed its acquisition of Pentaho this week, which means Pentaho’s big data analytics technology will be showing up in HDS storage products soon.

Pentaho software will be part of the Hitachi Scale-Out Platform (HSP) hyper-converged system launched at HDS Connect last month. HDS will also use Pentaho in a Hitachi Unified Compute Platform (UCP) product for SAP HANA and Hadoop to analyze big data.

Pentaho’s standalone and embedded software for analytics, data integration and visualization is a big part of the HDS social innovation strategy the company highlighted during its Connect conference. Hitachi is trying to become a leader in the Internet of Things market, including storage and other infrastructure products.

That means analytics will play a big role in nearly all of its products going forward, said Sarah Gardner, HDS CTO of social innovation.

“Internet of things solutions are not designed to operate in the background,” she said. “We need to wire them into other parts of the environment. The days of people wanting standalone analytics are gone.”

HDS disclosed its intention to acquire Pentaho in February. Pentaho will operate independently as Pentaho, a HDS company, according to HDS.

Violin still searching for right notes

Dave Raffo Dave Raffo Profile: Dave Raffo
Violin Memory

The red hot all-flash array remains ice cold for Violin Memory.

Violin reported revenue of $12.1 million for last quarter. That was down 33.3 percent from last year and 41 percent from last quarter, and well below the vendor’s previous forecast of from $21 million to $24 million. Violin lost $26.5 million for the quarter, which was actually an improvement over the $46.8 million loss from the previous quarter.

“Our first quarter results fell far short of our prior guidance and expectations as Violin continued to manage through the short-term effects of transitioning our customer base to our new flash storage platform,” Violin CEO Kevin DeNuccio said during the vendor’s earnings conference call.

Violin’s numbers look especially paltry when you consider EMC executives claim their XtremIO all-flash system is on track to exceed $1 billion in revenue for 2015.

DeNuccio blamed poor sales on a transition to Violin’s new 7300 and 7700 Flash Storage Platform (FSP) arrays, which include storage services that were missing from its old 6000 Series. He said those features – particularly inline deduplication and compression – are required to compete with market leaders EMC and Pure Storage.

DeNuccio predicts Violin will get a significant chunk of what he expects will become a $15 billion annual market for flash in primary storage after people get a good look at the FSP arrays. He said Violin has already brought in $11 million in revenue in May to kick off the current quarter, mainly from deals that did not close by the end of last quarter.

Still, Violin forecasted only from $16 million to $20 million in revenue this quarter.

“We think the quarter outlook is still strong, but after missing two quarters in a row, we are being very cautious in the kind of guidance that we give,” he said.

He said a product transition is a significant drag on a “one-product company.” But he claimed Violin’s one product is in the right segment to ride a coming wave. DeNuccio claimed the all-flash array market is reaching a “tipping point” as customers are ready to move completely off hard disk drives for primary storage.

“We are seeing early adopters that no longer want to purchase additional disk or hybrid arrays going forward and they recognize the transformational advantages of an all-flash storage infrastructure with enterprise data services that Violin can now deliver,” he said.

NetApp names new CEO

Carol Sliwa Carol Sliwa Profile: Carol Sliwa

NetApp announced a changing of the guard at CEO and chairman of the board after the market close today, less than two weeks after another disappointing earnings report.

CEO Tom Georgens departed after nearly 10 years at NetApp, and George Kurian, the company’s vice president of product operations, has replaced him. Kurian joined NetApp in 2011 and, since September 2013, has overseen the strategy and development of the company’s product portfolio. Kurian was also appointed to the board of directors.

NetApp also said Mike Nevens, lead independent director, was elected chairman of the board to replace Georgens, who held the position since April 2014. Nevens has served on NetApp’s board since December 2009. He is a senior advisor to Permira, an internal private equity fund, and he also serves on the boards of directors of Altera Corp. and Ciena Corp., according to NetApp’s Web site. Nevens is a retired director (senior partner) of McKinsey & Co., where he led the company’s global technology practice.

“While we intend to conduct a CEO search, we have the utmost confidence in George’s ability to lead the company, given his deep knowledge of NetApp and support from a strong executive team,” Nevens said via a prepared statement. “George has deep relationships with customers and partners globally and is committed to strengthening those relationships going forward.”

A NetApp spokesperson added, “The board believes that conducting a search is the appropriate course of action. George is the lead internal candidate for this position. He was part of our CEO succession plan and brings a wealth of experience to the role.”

Kurian’s appointment comes at a time of slumping earnings for NetApp and several other major storage vendors. NetApp announced on May 20 that its $1.54 billion in quarterly net revenue and $6.12 billion in annual revenue for the 2015 fiscal year were down on a year-over-year basis. The company also confirmed through an SEC filing plans to cut about 500 employees.

One of NetApp’s main troubles has been getting customers to move to its latest Clustered Data OnTap operating system. Many of the company’s largest customers waited for feature parity with the legacy version of Data OnTap, and that didn’t happen until the late 2014 release of clustered Data OnTap 8.3, Georgens noted during NetApp’s May 20 earnings call.

Georgens said the company underestimated the disruption the transition to Clustered OnTap had on the direct and indirect pipeline. He noted that Clustered OnTap represents a “re-architected and modernized version” of OnTap, and large customers have to undertake complex planning to update their existing storage management processes and migrate their data.

Channel partners typically guide smaller customers through the upgrade process, and some partners that were not well versed in selling Clustered Data OnTap saw customers defer upgrades, according to Georgens. Plus, the drive to Clustered Data OnTap hurt NetApp’s ability to attract new customers, he said.

NetApp also has been slow with the release of its all-flash FlashRay appliance. The company instead has relied on all-flash and hybrid version of its EF Series and FAS arrays to compete in the hot flash market. But, Georgens has claimed the company has sold significant amounts of flash through those products.

NetApp’s stock price plummeted during the first five months of this year from $41.68 per share at the close of business on January 1 to $33.16 at the close of business today.

Kurian said via a prepared statement that he is “honored to lead NetApp during this time of transition.” He cited key investment areas of “accelerating Clustered Data OnTap adoption, regaining traction in the channel, and increasing our sales capacity.”

Prior to serving as NetApp’s executive VP of product operations, Kurian served as senior vice president of the Data OnTap group and oversaw the product roadmap and engineering execution of Data OnTap and the associated On Command storage management product portfolio. Before that, Kurian served as senior vice president of NetApp’s storage solutions group.

Kurian came to NetApp from Cisco, where he was vice president and general manager of the application networking and switching technology group. He was responsible for modular campus LAN switching and WAN application delivery. He also previously worked on Cisco’s product development to enable Ethernet-based converged networks for video, voice and data.

Kurian’s prior employers also include Akamai Technologies, McKinsey & Co. and Oracle Corp. He holds a Bachelor of Science degree in electrical engineering from Princeton and an MBA from Stanford.

Georgens joined NetApp in October 2005 as executive vice president and general manager of enterprise storage systems. He was promoted to executive vice president of product operations in January 2007. Georgens succeeded Dan Warmenhoven as CEO in August 2009 and as chairman of the board in April 2014.

Veeam adds EMC to snapshot support list

Dave Raffo Dave Raffo Profile: Dave Raffo

Veeam will add snapshot integration with EMC VNX and VNXe storage arrays when it rolls out its Availability Suite 9.

Virtual backup specialist Veeam began integrating with storage arrays for more efficient backup and recovery of snapshots in 2013 with support for Hewlett-Packard 3PAR and StoreVirtual arrays. It added support for NetApp arrays in version 8 of its backup and recovery suite last year.

The integration allows Veeam Backup from Storage Snapshots to create snapshots faster by offloading the process to the supported arrays.

“One of our strategies is to integrate with primary vendors and their snapshot capabilities,” said Doug Hazelman, Veeam VP of product strategy. “This provides two capabilities. First, you get faster, more efficient snapshots because we can leverage the power of a primary storage array. The second is on the recovery side, we can see existing snapshots on the array and we can provide recovery operations from the array.

Veeam Availability Suite’s Enterprise Plus Edition is required for Backup from Storage Snapshots.

Availability Suite 9 is months away from release, but, as usual, Veeam will pre-announce features in advance.

“We’ll have rolling thunder through the next couple of months talking about new features,” Hazelman said.
