Nex-gen Fibre Channel will do 128-gig in the fast lane(s)



Posted by: Sonia Lelii

With an eye on hyper-scale virtualization and solid-state storage, the Fibre Channel Association (FCIA) today laid out the roadmap for the Gen 6 Fibre Channel (FC) industry standard protocol that allows a bare speed of up to 128 Gbps for storage area networking (SANs).

Gen 6 is 32-Gbps FC, but it will reach 128-gig through four striped lanes. Until now, each generation of FC technology has doubled bandwidth from the previous generation. Gen 5, which has been available since 2011 but is still in the relatively early days of adoption, supports 16-Gbps bandwidth. Gen 6 will be the first time an FCIA standard includes specifications to stripe four lanes.

“What people see is one connector from the host side and underneath it is made up of four lanes,” said Mark Jones, President of FCIA and director of technical marketing at Emulex. “Gen 6 is comprised of both 32 Gbps and 128 Gbps in parallel speeds.”

Gen 6 is expected to hit the market in 2016. It will provide 6,400 MBps full-duplex speeds, twice that of Gen 5 FC.

“We have never been able to come to an agreement of four set of lanes,” said Skip Jones, chairman of the FCIA and director of technical marketing at QLogic. “With four lanes, you are aggregating each lane and put them in sequence. It’s not four trunked lanes. It looks like a small 128-port all the way up to the APIs.”

Emulex’s Jones said Gen 6 also includes several features that go beyond speeds, which include Error Code Correction (EEC) to maintain the quality of the links to keep the error rate low and ensure data quality. The Gen 6 Fibre Channel protocol also is backwards compatible and better encryption, meaning it supports the 800-131a information security standard of the National Institute of Standards and Technology (NIST).

“[Backward compatibility] is not new but we want to emphasize this because we thought we might lose people when we talk about 128 Gbps,” said Jones, of Emulex.

Gen 6 also includes N-Port ID Virtualization (NPIV), which is an ANSI T11 standard that describes how a single Fibre Channel physical HBA port can register with a fabric using several worldwide port names (WWPNs) that might be considered Virtual WWNs.

“We are finding [NPIV] use is expanding among our user base,” said Emulex’s Jones.

George Crump, president and founder of Storage Switzerland, said it will be interesting to see how Gen 6 affects the server-side flash market because customers in this area generally are concerned with network latency.

“Gen 6 could cause people not to do server-side flash,” said Crump. “This has the potential to forestall some from going to server-side flash. Gen 6 will also drive down the price of Gen 5.”

Something’s wrong when storage vendors pitch speeds and feeds



Posted by: Randy Kerns
Storage

I’m surprised to hear from IT people that storage vendors are still using “speeds and feeds” in their sales pitches. Salesmen for these companies talk about how fast and how big the storage systems could be.

When I asked what specific details were being emphasized, the list included:

  • Bandwidth – The maximum total bandwidth the system could support was presented.
  • IOPS – The aggregate number of a fully configured system was given without information regarding the response time.
  • Type of processor, clock rate of processor, and number of processor cores for the controller.

Maybe the presentations included more about the function and value of the storage system being, but this was the information relayed by customers.

I thought storage sales had moved beyond that.  Most customers are looking to solve specific problems or address some complex workload needs.  The most basic for traditional IT environments include:

  • Capacity growth. There is a need for more storage but not at the sacrifice of getting the same relative amount of work completed.  This means not just adding capacity, but having the same ability to access the capacity.  This is usually measured as accessed density, which is the number of I/O’s possible divided by the capacity.
  • Workload requirements. Some workloads need improvement.  Most commonly cited needs are improving transaction processing, increasing the virtual machine density (number of VMs per physical server), and the number of virtual desktops supported per physical server and storage system.  These have performance needs but are much more complex than speeds and feeds numbers presented.  Necessary improvements include the latency per I/O to allow write-dependent transactions to move ahead.  Using an aggregate number of IOPS can be a very misleading number in this case.
  • Consolidation of storage with a technology upgrade. This is usually a generational change for storage that can be caused by the end of the financial life of the storage system (usually dictated by increased cost of maintenance) or perceived technical obsolescence.  The expectation is the new system will provide greater capacity and performance to allow consolidation of multiple older storage systems.  This brings improvements in the amount of power, cooling, and physical space required.  Consolidation is really a workload discussion as well.

The simple speeds and feeds sales approach is a throwback.  Most sales have moved beyond this, recognizing the sale is all about solving a problem or meeting a need for the customer.  In solving a problem or meeting a need, the salesmen must understand the customer and not just present the speeds and feeds attributes. Proposing a product with a focus on those attributes can only short-circuit that understanding.  It pushes the responsibility for finding the correct solution onto the customer.

This brings to mind the recent Super Bowl commercial from Radio Shack with stars from the 1980’s and the message “The 80’s called.  They want their store back.”  Within days after airing, Radio Shack announced the closing of 500 stores.  Maybe this should be a hint about the speeds and feeds sales approach.

DataGravity drops hints about data management product while building channel



Posted by: Dave Raffo
Storage

DataGravity, the storage startup founded by EqualLogic veterans Paula Long and John Joseph, is in the whisper stage about its product that is scheduled to launch this year.

The startup is still keeping product details under wraps, and won’t get any more specific on a launch data than to say it will be generally available in 2014. But DataGravity will have a team headed by president Joseph at VMware Partner Exchange this week to woo channel partners. Joseph said DataGravity’s unstructured data management system is in beta following an alpha program that started last June.

Joseph said the DataGravity product will sell as an appliance, with the hardware serving as a delivery mechanism for the software that will manage, analyze and unlock the business value of file data.

“We want to get out of being a box pusher and into offering data solutions,” Joseph said of the system. “I would like to bring insight to our customers’ file-oriented business content.”

Joseph said he expects the appliance to be installed by a storage administrator, but will be a tool for business units rather than merely for storing data.

“The value starts in IT and motions out to the line of business,” he said. “We have the capability that IT people will love, but people in the legal department, finance, HR and marketing are going to say ‘Holy smokes, my time to answer has been cut in half by using this product and it’s so user-friendly I can get what I need in a fraction of the time.’”

Long, who was responsible for the engineering expertise behind the EqualLogic iSCSI SAN startup that Dell acquired for $1.4 billion in 2008, isn’t talking technology yet regarding DataGravity. In a YouTube video produced to drop hints about the product, CEO Long says DataGravity is “out to change table stakes for storage,” is “turning the light on to your data” and “will bring color and flavor and language to your storage.”

So if your storage looks and tastes bland and doesn’t say much, DataGravity will change all that.

VMware’s picking its storage friends more carefully



Posted by: Dave Raffo
Storage

VMware historically has had a good relationship with storage vendors, especially those who focus on storing and protection for virtual machines. The annual VMworld conference draws more storage vendors than any storage-dedicated show. The VMware Partner Exchange (PEX) show has also been storage vendor-friendly, although less so this year.

As first reported by CRN, VMware asked Nutanix and Veeam Software to stay away from PEX next week. Those two vendors have had success with products that help organizations running VMware hypervisors. Nutanix sells hyper-converged systems that include storage, servers and VMware hypervisors in one box, and Veeam sells backup for virtual machines.

But VMware has also become more competitive with Nutanix and Veeam as VMware expanded its capabilities and products over the past couple of years. VMware’s Virtual SAN (vSAN), currently in beta, is a software-only version of what Nutanix does. Nutanix also competes with Vblocks, sold by the VCE joint venture comprised of VMware, its parent EMC and Cisco. And VMware’s vSphere Data Protection (VDP) backup product, an OEM version of EMC’s Avamar software, directly competes with Veeam’s Backup & Recovery.

Still, VMware isn’t telling all hyperconverged systems and VM backup vendors to stay away from PEX. SimpliVity, which also sells hyper-converged systems that bundle VMware hypervisors, will be at the show and its CEO Doron Kempel will be a speaker. Unitrends PHD, which also handles VM backups, will also be there.

Why Nutanix and Veeam? Maybe because of their success. They are among the fastest growing storage vendors, according to the numbers released by the private companies. Nutanix claims it has gone over $100 million in revenue in barely two years of selling products, and forecasts more than $80 million for 2014. Veeam claims its annual revenue passed $100 million in 2012, and that its software protects more than 5.5 million VMs. These vendors can also be seen as growing threats to EMC and VMware’s larger storage partners, including NetApp, Dell, Hewlett-Packard and IBM.

Although Veeam now protects Microsoft Hyper-V VMs too, it much of its early success came from customer referrals from VMware. Doug Hazelman, Veeam vice president of product strategy, said he would not speculate why Veeam is no longer welcome at VPX but said his company still considers VMware an ally.

“We still have a good relationship with VMware,” he said. “The vast majority of the more than 80,000 customers we have are running on VMware. In the software industry there is always overlap between vendors like VMware and Microsoft and their partners, and Veeam is no different.”

Hazelman wouldn’t say if he thought being officially absent from PEX will hurt business, but he said Veeam will send a team to the show for meetings with VMware partners. “We have a strong and vocal customer base and partner base,” he said. “Just because we may not be on the show floor or at the partner exchange, doesn’t mean we won’t be out there.”

Report: FC faster, more reliable than FCoE — and requires fewer cables



Posted by: Dave Raffo
Storage

Despite all the hyper around Fibre Channel over Ethernet (FCoE) a few years ago, old fashioned Fibre Channel (FC) remains the dominant SAN protocol.

A report released today by technology research firm Evaluator Group shows there is good reason for that. Evaluator Group testing found FC significantly faster than FCoE with far less CPU utilization. FC also required fewer cables and power than FCoE, according to the report.

Before we get into the numbers, I want to point out that FC-centric Brocade funded the testing. Brocade sells FCoE gear too, but has been more bullish on FC while its rival Cisco has been FCoE’s chief evangelist. That doesn’t mean the results were skewed – Evaluator Group senior partner Russ Fellows said his group conducted the tests at its labs without vendor interference – but Brocade may not have released the results if FC did not come out a clear winner.

Evaluator Group used Hewlett-Packard BladeSystem c7000 chassis and 16 Gbps FC switching and HBAs on the FC side. For FCoE, Evaluator Group used Cisco UCS 5108 blade chassis and 10-Gigabit Ethernet (GbE) switching. In both cases, the storage was a 16-gig FC solid-state arrays.

The difference in response times for FC and FCoE didn’t show up until workloads surpassed 70% SAN utilization. However, FC response times were two to 10 times faster than FCoE as workloads surpassed 80% SAN utilization. FC also used 20 percent to 30 percent less CPU power than FCoE according to the report.

Speed and low latency aren’t FCoE selling points, so those results were no big surprise. A need for less cabling and power are supposed to be FCoE’s advantages, however, so it was a surprise that FC required 50% fewer cables for LAN and SAN connectivity. “This highlights and confirms the inaccuracy of the FCoE claims of fewer cables and connections,” the report states.

The tests also found the Cisco UCS required 50% more power and cooling than the HP blade with FC equipment.

The tests also determined that FC has more predictable performance with FCoE, which had twice as great a difference between average and standard deviation at 50% utilization than FC. The difference was 10 times as great with 90% workload utilization.

“If you have a high-performing application and use solid state storage, Fibre Channel is the better way to go,” Fellows said. “There is less overhead and better performance. I was surprised that Fibre Channel looked as much better than it did. The cabling and power advantage was a bit of a surprise, too.”

Fellows added that CPU utilization was almost identical when using a hardware initiator for FCoE. The test results for the report used a software initiator because that is the standard configuration for UCS, but FCoE performed better in subsequent tests using hardware initiators.

FCoE adoption for storage has been slow, for several reasons. Fellows said that while FCoE performance is good enough for many workloads, he doesn’t expect it to supplant FC any time soon. “It will continue to roll out, but I don’t think adoption will be that strong,” he said. “I think FCoE will be similar to iSCSI – it will work, people will use it and it will expand, but iSCSI hasn’t taken over the world yet.”

Violin hires new CEO — will he hold or sell?



Posted by: Dave Raffo
Storage

Violin Memory today named Kevin DeNuccio as its CEO, and he must decide if he wants to try and turn around the struggling all-flash array vendor or sell it off.

DeNuccio replaces interim CEO Howard Bain, who held that position since Violin’s board fired Don Basile in December. Bain remains Violin’s chairman. Basile cut his remaining tie with Violin when he officially resigned from the board last Friday. DeNuccio, who also has the title of president, replaced Basile on the Violin board.

Basile left as CEO less than three months after Violin went public, and saw its stock price plummet from its initial public offering of $9 to $2.68. It didn’t help Basile that Violin’s first earnings report as a public company was disappointing, as it lost $34.1 million and missed its revenue and guidance targets.

Clinton Group, a Violin investor, has been pushing the board to sell the company. Clinton Group president Gregory Taxin wrote a letter to the Violin board in December urging it to sell the company. Last week he told Bloomberg at the Activist Investor Conference that Violin has received informal inquiries from five suitors.

DeNuccio won’t be making any public statements for at least a few days according to a Violin spokesperson, who said the new CEO will be tied up in meetings with employees, partners, investors and customers.

Although he is a director for solid-state drive (SSD) vendor SanDisk, DeNuccio’s background goes far deeper in telecommunications that storage. He most recently managed angel investor Wild West Capital, which he founded in 2012. He also served as CEO of Metaswitch Networks from 2010-2012 and Redback Networks from 2001-2008. He took Redback through Chapter 11 bankruptcy before sellng it to Ericcson. He also held executive positions with Bell Atlantic Network Integration, Cisco, Wang Laboratories and Unisys Corp.

Quorum sets out to one-click its way to DR supremacy



Posted by: Dave Raffo
Storage

Data protection appliance vendor Quorum enters 2014 coming off what it claims are record sales with expectations to grow more this year, a fresh $10 million funding round and a still-emerging cloud DR market in front of it. At the same time, the company is in transition as it searches for a new CEO to manage its expected expansion.

Walter Angerer, who works for one of Quorum’s venture capitalists and sits on its board, became interim CEO in November when the company announced its latest funding. He replaced Larry Lang, who served as CEO since 2010.

“As you go through growth cycles, you grow out of the startup phase and enter a growth phase,” Angerer said, explaining the reason for the CEO change. “It was appropriate for us to hand things over to new leadership to accelerate growth.”

Angerer said he hopes to find a new CEO soon. He has reason to find somebody quick. Besides his role as a venture partner with Quorum VC Toba Capital, Angerer is also founder CEO of Parsec Labs, a NAS virtualization startup preparing to roll out its first products.

Quorum has already begun revamping its executive team with the addition of VP of marketing John Gallagher and VP of products Kemal Balioglu. Gallagher has storage experience with DataDirect Networks, LSI and EMC Isilon. Like Angerer, Balioglu spent time at Symantec.

Quorum bills its onQ appliances as “one-click” backup and recovery. Customers can use an appliance on-site and replicate to a second appliance at a DR site. Or, the second appliance can be hosted by a VAR or cloud provider.

Angerer said Quorum has close to 500 customers and it has doubled its revenue every year for the past three years. He predicts that Quorum will more than double revenue this year.

“There’s a lot more awareness and appreciation of the need for DR rather than just backup,” he said.

Gallagher said it will also be an active year for product releases. “Our engineering team is quite busy,” he said. “We’ll have core technology advances late in the first half of the year, and some more technologies that will expand or market in the second half.”

What does IBM’s server sale to Lenovo mean for storage?



Posted by: Randy Kerns
Storage

IBM’s sale of of its x86 server business to Lenovo raises questions about IBM storage.

Lenovo did not buy any storage systems in the $2.3 billion transaction, but it will OEM and license IBM Storwize storage arrays, tape systems and General Parallel File System (GPFS) software as part of the deal.

I see much potential impact on the storage business from this deal.  Certainly it is too soon to make any conclusions and even to speculate at this point.  But, there are some areas worth considering:

  • Storage sales are often server-led, meaning customers often buy new storage systems when they purchase servers. The x86 server line did have storage drag along with it. That’s part of the reason why Lenovo will OEM IBM storage, and may mitigate some of the disruption for customers. But will the sales drag continue for the Storwize systems? Lenovo is a low-cost provider and there will be pricing pressure.  And, Lenovo may want a more commodity priced offering.
  • Will the pricing pressure drive down the prices of storage overall and make the storage business less profitable?  With less profit, there will be less motivation to invest in development and the competitive pressures may be too great.
  • A possible upside is Lenovo’s success as a low-cost provider will drives more volume and increases profit, allowing greater investments in the storage business by IBM.
  • IBM’s service and support for enterprises has been a factor for customers buying IBM systems. Will that change after the acquisitions? This could be a hidden impact which will take some time to surface.
  • What about the IBM storage products not in the OEM deal?  This is less of an issue because these systems are primarily sold with the server systems that IBM has held on to (Power and System-z) or through independent storage sales. The Storwize systems should continue sales from IBM and its resellers for independent storage sales and with the Power servers as well.  But with Lenovo selling the Storwize and tape systems, will there be conflict with IBM?  There may be engagement rules established to handle this situation but we don’t’ know that yet.
  • What does the big picture look like for IBM? IBM is moving away from low-margin devices and systems. The threshold for selling off the business is not clear and probably for good business reasons.  But, the question comes down to whether the investment and resulting innovations in storage will produce enough added value to continue the investments.  IBM has an excellent portfolio of storage products currently and some great people in sales, support, and in the channel and distributors.  There is great potential to continue to be competitive and move forward with technology and solutions. This is what is expected of IBM.

With little growth in sight, EMC plans layoffs



Posted by: Dave Raffo
Storage

EMC’s earnings report Wednesday served as another reminder that storage spending is not growing at anywhere near the rate that data is. With more data spread around on mobile devices and the cloud, the storage model is changing and companies are not rushing out to buy more traditional storage arrays.

EMC’s $6.68 billion revenue last quarter was a big jump from its $5.54 billion in its disappointing third quarter. But EMC’s full year storage revenue of $23.22 billion fell short of the vendor’s original target of $24.5 billion, and its 2014 forecast of $24.5 billion was below Wall Street expectation. EMC executives said industry-wide storage revenue growth continues to slow, and the company announced it will reduce its staff by about 1,000 to cut costs.

The slowdown is clearly more industry-related than specific to EMC. Worldwide storage sales have been down overall this year, and IBM said its storage revenue dropped 13% year-over-year during its earnings call earlier this month.

“We are disappointed we didn’t hit our original goal of $23.5 billion in revenue,” EMC CEO Joe Tucci said, “We are, however, proud that we did hit our $5.5 billion free cash flow goal, grew considerably faster in the markets we serve, and substantially faster than the overall IT market.”

Tucci added that the transition in the IT business now presents “the biggest, most disruptive and yet most opportunistic transition in IT’s 60-plus year history.” However, he and EMC Information Infrastructure CEO Dave Goulden mentioned several times that CIOs are reluctant to buy in this market “We recognize that CIOs right now are being very cautious in their spend,” Goulden said. “We are seeing a little bit of a pause in the market … We are really factoring what we are seeing in the market and the dilemma that the CIOs are facing into our thoughts about how the year might play out. So we are taking a conservative view of IT spending.”

Tucci added that EMC expects the IT market to grow around only 2% this year, and EMC’s guidance represents a 3% gain over 2013.

As for the layoff, Goulden called it a “rebalancing activity” to put EMC’s workforce more in line with the current technology and product landscape. EMC had a similar layoff last May. The company has about 60,000 employees.

“Last year when we did this, we actually wound up with about 2,000 more people at the end of the year when we started off this,” he said. “This year we expect to probably end the year flat or slightly up. Just think of it as rebalancing rather than restructuring.”

Syncsort data protection becomes Catalogic



Posted by: Dave Raffo
Storage

Syncsort Data Protection has an official name, three months since splitting off from the Syncsort data integration company.

The data protection vendor Monday said it is now called Catalogic Software, and adopted the slogan “Catalog, protect, manage” to describe its DPX data protection and EPX catalog management applications.

The data protection spinoff came when part of its management team and new investors acquired that business from Syncsort. Flavio Santoni, who was CEO of Syncsort, is the Catalogic CEO. The rest of the Catalogic management team consists of chief marketing officer John McArthur, CTO Walter Curti, VP of sales Mike Kuehn, senior director of customer support Ira Goodman, and senior director of business development and alliances Bob Sarubbi.

Their goal now is to keep Catalogic from becoming catatonic in a highly competitive data protection market.
