- New Dell Storage array series, designed for mid-tier deployments, extends Dell’s intelligent data placement technology with an all-flash solution costing up to 72 percent less than competing arrays1
- New flash and hybrid arrays support diverse workload demands, including support for up to 10,000 Microsoft Exchange user mailboxes in a single 2U SAN3
- Dell expands software-defined storage portfolio with planned series of Web-scale converged appliances
Dell announced it will bring its high-end storage capabilities to mid-sized deployments with the creation of a new series of full-featured, enterprise storage arrays. Dell also shared details of its growing software-defined storage (SDS) ecosystem and plans to broaden its portfolio with new Dell converged server and storage appliances.
The new Dell Storage SC4000 Series arrays demonstrate Dell’s continued innovation to bring full-featured, enterprise-class storage to cost-efficient, high-performing, mid-tier solutions. With these new arrays, customers can achieve impressive all-flash performance – costing up to 72 percent less than competing pure flash arrays1 – or a highly cost-efficient combination of high-end flash performance and low-cost disk storage all in one array. The storage array series joins Dell’s customer-driven, enterprise data centre portfolio of purpose-built solutions designed to make IT more efficient and practical.
“The Dell Storage SC4000 Series is redefining the economics of enterprise storage, offering the advanced capabilities of larger-scale enterprise storage and outstanding price for performance to help customers with mid-tier storage needs become more competitive,” said Alan Atkinson, vice president and general manager, Dell Storage. “While Dell continues to make huge strides in evolving our storage portfolio with industry leading value propositions for customers seeking innovative SAN technology, we’re also supporting organisations opting for a revolutionary approach to data management by growing our portfolio of software-defined storage and converged solutions.”
New Dell Storage Arrays Bring Large-Scale, Enterprise-Class Features to Smaller Deployments
Supporting customers seeking high-performing and cost-efficient storage arrays at a smaller scale, the new Dell Storage SC4000 Series arrays will debut with the enterprise-class Dell Storage SC4020, a 2U, 24-drive storage area network (SAN). These enterprise-class arrays leverage technology from both the Dell Compellent and EqualLogic family of products, incorporating full-featured Dell Storage Center 6.5 array software and the EqualLogic iSCSI software stack. The new series supports both Fibre Channel and iSCSI connectivity and is designed to offer the same advanced capabilities as larger SANs in a solution sized and priced for mid-sized deployments.
The Dell Storage SC4020, which can scale to more than 400 terabytes of raw capacity, supports a wide range of workloads for organisations, across all industries and sizes, seeking a high-performing, mid-sized SAN entry point or a remote or branch office storage solution. For example, the Dell Storage SC4020 can host up to 10,000 Microsoft Exchange 2013 user mailboxes in a single 2U SAN with 24 hard disk drives or can achieve nearly 120,000 IOPS (input-output operations per second) with less than one millisecond latency for OLTP or mixed workloads.3
The new arrays will launch with the same intelligent data placement capability as the Dell Compellent SC8000 that moves data among traditional rotating drives, write-optimised flash (SLC), and read-optimised flash (MLC) drives to optimise overall storage costs. Customers can achieve all-flash performance for the price of 15K disk technology2 with real time tiering between flash drive types,thereby reducing storage costs and gaining from all-flash performance to support applications, such as OLTP database workloads, where previously all-flash storage might have been deemed cost prohibitive.
The Dell Storage SC4020 also provides an excellent replication partner for Dell Compellent SC8000 arrays, allowing customers to seamlessly connect and manage arrays together with a single, centralised management interface that can help simplify operations and reduce total cost of ownership. The new Dell Storage array series also offers customers:
- Unprecedented value with a highly efficient SAN and compact size, making it ideal for mid-sized needs or remote or branch office deployments
- Enterprise-class performance with dual controller capability and SAN optimised for all-flash or hybrid SSD/HDD configurations
- World class intelligence with advanced levels of automation and control to auto-tune the customer’s storage environment
- Advanced software capabilities such as real-time automated tiering, replication, thin provisioning, snapshots and centralised management for multiple local and remote SANs
- Perpetual software licensing that enables customers to pay only once for software features, even across hardware upgrades
- Unified storage with the ability to manage both block and file storage, with the Dell Fluid File System, from a single management console
- World class Dell Copilot support services that provide a combination of centralised support and 24×7 active system monitoring to help improve system performance and stability
Dell Grows Software-Defined Storage Portfolio
Dell also today announced growing support for a diverse set of software-defined storage solutions, broadening its partner ecosystem with a new go to market relationship with Nutanix. With the new agreement, Dell plans to offer customers the Dell XC Series of Web-scale Converged Appliances, which combine compute, storage and networking into a single offering, powered by Nutanix software. The new appliances will benefit customers seeking an integrated IT approach, offering simple deployment, management and scale as needed.
As SDS begins to find its way into the enterprise storage and the larger software-defined data centre discussions, some organisations are looking to move towards revolutionary solutions where the components – compute, storage and networking – are tuned to work together for optimised application performance and ease of management and scale through automation and IT orchestration.
With a focus on delivering end-to-end data centre capabilities, Dell offers customers multiple SDS options, along with its partners, whereDell hardware, services and support are integral to the solutions. Dell’s broad and open approach to SDS includes integration with open source platforms and leading hypervisor vendors to provide a breadth of customer-centric SDS solutions to address various business needs.
- The Dell Storage SC4000 Series will be available worldwide during the third quarter of 2014.
- The Dell XC Series of Web-scale Converged Appliances have planned worldwide availability during the fourth quarter of 2014.
Airbus CEO urges trade war ceasefire, easing of COVID travel bans
By Tim Hepher
PARIS (Reuters) – The head of European planemaker Airbus called on Saturday for a “ceasefire” in a transatlantic trade war over aircraft subsidies, saying tit-for-tat tariffs on planes and other goods had aggravated damage from the COVID-19 crisis.
Washington progressively imposed import duties of 15% on Airbus jets from 2019 after a prolonged dispute at the World Trade Organization, and the EU responded with matching tariffs on Boeing jets a year later. Wine, whisky and other goods are also affected.
“This dispute, which is now an old dispute, has put us in a lose-lose situation,” Airbus Chief Executive Guillaume Faury said in a radio interview.
“We have ended up in a situation where wisdom would normally dictate that we have a ceasefire and resolve this conflict,” he told France Inter.
Boeing was not immediately available for comment.
Brazil, which has waged separate battles with Canada over subsidies for smaller regional jets, on Thursday dropped its own complaint against Ottawa and called for a global peace deal between producing nations on support for aerospace.
Faury said the dispute with Boeing was particularly damaging during the COVID-19 pandemic, which has badly hit air travel and led to travel restrictions or border closures. He expressed particular concern about widening bans within Europe.
“We are extremely frustrated by the barriers that restrict personal movement and it is almost impossible today to travel in Europe by plane, even domestically,” he said.
“The priority no. 1 for countries in general is to reopen frontiers and allow people to travel on the basis of tests and then eventually vaccinations.”
The comments come as businesses increase pressure on governments to reopen economies as coronavirus vaccine roll-outs gather pace across Europe.
France has defended recently introduced border restrictions, saying they will help the government avoid a new lockdown and stay in force until at least the end of February.
Germany installed border controls with the Czech Republic and Austria last Sunday, drawing protest from Austria and concerns about supply-chain disruptions.
Berlin calls the move a temporary measure of last resort.
Poland said on Saturday it had not ruled out imposing restrictions at the country’s borders with Slovakia and the Czech Republic due to rising COVID-19 cases.

Why a predictable cold snap crippled the Texas power grid
By Tim McLaughlin and Stephanie Kelly
(Reuters) – As Texans cranked up their heaters early Monday to combat plunging temperatures, a record surge of electricity demand set off a disastrous chain reaction in the state’s power grid.
Wind turbines in the state’s northern Panhandle locked up. Natural gas plants shut down when frozen pipes and components shut off fuel flow. A South Texas nuclear reactor went dark after a five-foot section of uninsulated pipe seized up. Power outages quickly spread statewide – leaving millions shivering in their homes for days, with deadly consequences.
It could have been far worse: Before dawn on Monday, the state’s grid operator was “seconds and minutes” away from an uncontrolled blackout for its 26 million customers, its CEO has said. Such a collapse occurs when operators lose the ability to manage the crisis through rolling blackouts; in such cases, it can take weeks or months to fully restore power to customers.
Monday was one of the state’s coldest days in more than a century – but the unprecedented power crisis was hardly unpredictable after Texas had experienced a similar, though less severe, disruption during a 2011 cold snap. Still, Texas power producers failed to adequately winter-proof their systems. And the state’s grid operator underestimated its need for reserve power capacity before the crisis, then moved too slowly to tell utilities to institute rolling blackouts to protect against a grid meltdown, energy analysts, traders and economists said.
Early signs of trouble came long before the forced outages. Two days earlier, for example, the grid suddenly lost 539 megawatts (MW) of power, or enough electricity for nearly 108,000 homes, according to operational messages disclosed by the state’s primary grid operator, the Electric Reliability Council of Texas (ERCOT).
The crisis stemmed from a unique confluence of weaknesses in the state’s power system.
Texas is the only state in the continental United States with an independent and isolated grid. That allows the state to avoid federal regulation – but also severely limits its ability to draw emergency power from other grids. ERCOT also operates the only major U.S. grid that does not have a capacity market – a system that provides payments to operators to be on standby to supply power during severe weather events.
After more than 3 million ERCOT customers lost power in a February 2011 freeze, federal regulators recommended that ERCOT prepare for winter with the same urgency as it does the peak summer season. They also said that, while ERCOT’s reserve power capacity looked good on paper, it did not take into account that many generation units could get knocked offline by freezing weather.
“There were prior severe cold weather events in the Southwest in 1983, 1989, 2003, 2006, 2008, and 2010,” Federal Energy Regulatory Commission and North American Electric Reliability Corp staff summarized after investigating the state’s 2011 rolling blackouts. “Extensive generator failures overwhelmed ERCOT’s reserves, which eventually dropped below the level of safe operation.”
ERCOT spokeswoman Leslie Sopko did not comment in detail about the causes of the power crisis but said the grid’s leadership plans to re-evaluate the assumptions that go into its forecasts.
The freeze was easy to see coming, said Jay Apt, co-director of the Carnegie Mellon Electricity Industry Center.
“When I read that this was a black-swan event, I just have to wonder whether the folks who are saying that have been in this business long enough that they forgot everything, or just came into it,” Apt said. “People need to recognize that this sort of weather is pretty common.”
This week’s cold snap left 4.5 million ERCOT customers without power. More than 14.5 million Texans endured a related water-supply crisis as pipes froze and burst. About 65,000 customers remained without power as of Saturday afternoon, even as temperatures started to rise, according to website PowerOutage.US.
State health officials have linked more than two dozen deaths to the power crisis. Some died from hypothermia or possible carbon monoxide poisoning caused by portable generators running in basements and garages without enough ventilation. Officials say they suspect the death count will rise as more bodies are discovered.
THIN POWER RESERVE
In the central Texas city of Austin, the state capital, the minimum February temperature usually falls between 42 and 48 degrees Fahrenheit (5 to 9 degrees Celsius). This past week, temperatures fell as low as 6 degrees Fahrenheit (-14 degrees Celsius).
In November, ERCOT assured that the grid was prepared to handle such a dire scenario.
“We studied a range of potential risks under both normal and extreme conditions, and believe there is sufficient generation to adequately serve our customers,” said ERCOT’s manager of resource adequacy, Pete Warnken, in a report that month.
Warnken could not be reached for comment on Saturday.
Under normal winter conditions, ERCOT forecast it would have about 16,200 MW of power reserves. But under extreme conditions, it predicted a reserve cushion of only about 1,350 MW. That assumed only 23,500 MW of generation outages. During the peak of this week’s crisis, more than 30,000 MW was forced off the grid.
Other U.S. grid operators maintain a capacity market to supply extra power in extreme conditions – paying operators on an ongoing basis, whether they produce power or not. Capacity market auctions determine, three years in advance, the price that power generators receive in exchange for being on emergency standby.
Instead, ERCOT relies on a wholesale electricity market, where free market pricing provides incentives for generators to provide daily power and to make investments to ensure reliability in peak periods, according to economists. The system relied on the theory that power plants should make high profits when energy demand and prices soar – providing them ample money to make investments in, for example, winterization. The Texas legislature restructured the state’s electric market in 1999.
Since 2010, ERCOT’s reserve margin – the buffer between generation capacity versus forecasted demand – has dropped to about 10% from about 20%. This has put pressure on generators during demand spikes, making the grid less flexible, according to North American Electric Reliability Corporation (NERC), a nonprofit regulator.
That thin margin for error set off alarms early Monday morning among energy traders and analysts as they watched a sudden drop in the electrical frequency of the Texas grid. One analyst compared it to watching the pulse of a hospital patient drop to life-threatening levels.
Too much of a drop is catastrophic because it would trigger automatic relay switches to disconnect power sources from the grid, setting off uncontrolled blackouts statewide. Dan Jones, an energy analyst at Monterey LLC, watched from his home office in Delaware as the grid’s frequency dropped quickly toward the point that would trigger the automatic shutdowns.
“If you’re not in control, and you are letting the equipment do it, that’s just chaos,” Jones said.
By Sunday afternoon about 3:15 p.m. (CST), ERCOT’s control room signaled it had run out of options to boost electric generation to match the soaring demand. Operators issued a warning that there was “no market solution” for the projected shortage, according to control room messages published by ERCOT on its website.
Adam Sinn, president of Houston-based energy trading firm Aspire Commodities, said ERCOT waited far too long to start telling utilities to cut customers’ power to guard against a grid meltdown. The problems, he said, were readily apparent several days before Monday.
“ERCOT was letting the system get weaker and weaker and weaker,” Sinn said in an interview. “I was thinking: Holy shit, what is this grid operator doing? He has to cut load.”
Sinn said he started texting his friends on Sunday night, warning them to expect widespread outages.
‘SECONDS AND MINUTES’
Early Monday morning, one of the largest sources of electricity in the state – the unit 1 reactor at the South Texas Nuclear Generating Station – stopped producing power after the small section of pipe froze in temperatures that averaged 17 degrees Fahrenheit (9 degrees Celsius). The grid lost access to 1,350 MW of nuclear power – enough to power about 270,000 homes – after automatic sensors detected the frozen pipe and protectively shut down the reactor, said Victor Dricks, a spokesman for the U.S. Nuclear Regulatory Commission.
About 2:30 a.m. (CST), the South Plains Electric Cooperative in Lubbock said it received a phone call from ERCOT to cut power to its customers. Inside the ERCOT control room, staff members scrambled to call utilities and cooperatives statewide to tell them to do the same, according to operational messages disclosed by the grid operator.
Three days later, ERCOT Chief Executive Bill Magness acknowledged that the grid operator had only narrowly avoided the calamity of uncontrolled blackouts.
“If we hadn’t taken action,” he said on Thursday, “it was seconds and minutes (away), given the amount of generation that was coming off the system at the same time that the demand was still going up.”
