Hacer un rescan de discos iSCSI

En el caso que hayamos cambiado el tamaño de un disco iSCSI, vamos a necesitar hacer un rescan de las sesiones iSCSI

Vamos a suponer que hemos ampliado el siguiente disco:

# fdisk -l /dev/sdb

Disk /dev/sdb: 32.2 GB, 32212254720 bytes
64 heads, 32 sectors/track, 30720 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       30720    31457264   83  Linux

Mediante iscsiadm podemos hacer el rescan de las sessiones iSCSI:

# iscsiadm -m node -R
Rescanning session [sid: 1, target: iqn.1992-08.com.netapp:sn.193472889, portal: 10.12.16.222,3260]

A continuación veremos el nuevo tamaño del disco:

# fdisk -l /dev/sdb

Disk /dev/sdb: 85.8 GB, 85899345920 bytes
64 heads, 32 sectors/track, 81920 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       30720    31457264   83  Linux

A Look into Cloudian’s HyperStore 4000

Cloudian has come up with a new cloud data archiving product called HyperStore 4000 that promises to have many unique features to support the changing needs of businesses.

HyperStore 4000 offers object storage, which means, data is stored as objects and not as files. The obvious advantage is that each object acts as a single repository instead of a file system where documents are nested within subfolders.

This cloud archiving option comes with a storage of 700 TB, and even has two separate computer nodes for every chassis. Essentially, what this means is there is a high level of flexibility for data storage, as it can be configured as a three-way cluster. In addition, it ensures the highest levels of data availability as it has a built-in cloud tiering system.

With this product, customers have the choice to store data on their own premises or on popular cloud platforms like AWS, Microsoft Azure and Google Cloud. This data can tier to Cloudian’s public cloud as well.

HyperStore 4000 is the perfect addition to Cloudian’s line of products as it combines their existing expertise with what businesses need today. Data is growing at astronomical speeds. According to a report published by IDC, the amount of data is doubling in size every two years, and this means, by 2020, we’ll reach 44 zettabytes (equivalent to 44 trillion gigabytes). Such a rapidly growing data needs ample storage space, and this is exactly what HyperStore 4000 offers with its 700 TB space.

According to Jon Toor, the Chief Marketing Officer of Cloudian, this device will be particularly useful for industries that deal with large amounts of data such as genome sequencing companies, video surveillance units, and those involved in the entertainment industry. These industries prefer large on-premise storage than cloud simply because it’s safe and they know where their data is located. He also opined that it could replace tape archives that are slowly going out of existence.

In terms of pricing too, Cloudian’s HyperStore 4000 gives a competitive deal. A report released by the company says that this device offers on-premise performance at the price of cloud services, as it costs 40 percent less per GB when compared to other products from Cloudian. This lower pricing is Cloudian’s way of establishing itself in a market that is being dominated by cloud providers with extensive infrastructure.

In fact, one of the biggest reasons for many companies to move to the cloud is cost-saving. If Cloudian can offer the same cost, there is a high possibility for customers to buy HyperStore 4000. To top it, the many recent reports about hacking and data loss has brought up renewed concerns about cloud security. So, when Cloudian offers a solution that is safer than cloud, but at the same price, many businesses are sure to look into it.

In short, Cloudian has come up with a competitive market to bridge the gap that exists between cloud and on-premise storage. Its competitive price, abundant storage and easy-to-use features can after all make businesses reconsider their data archiving strategies.

Cisco Introduces New Products

Cloud applications are becoming an integral part of everyday life, both at the personal and professional level. It’s little wonder that companies are vying with each other to tap into this huge market. The latest company to join this bandwagon of enterprise cloud suite applications is Cisco, with the introduction of ONE Enterprise Cloud Suite.

Introduced at Cisco’s Partner Summit in San Francisco on November 1st, ONE Enterprise Cloud Suite is a hybrid cloud software solution that’ll allow companies to make the most of their cloud environment. In many ways, this is a self-service portal that is customized to meet the needs of end-users, app developers, and IT professionals, so they can have a flexible environment backed by a solid infrastructure. It’ll offer advanced automation tools for managing the infrastructure, cloud, and other related services by providing real-time diagnostics and historical analysis. One of the most important features of ONE Enterprise Cloud Suite is Big Data automation, so as to provide higher levels of consistency and reduced risk.

Besides this cloud enterprise suite, Cisco also announced a new storage server called UCS S3260. Part of its Cisco Unified Computing System (UCS), this is the first offering in UCS S-series of servers. Known for its modular architecture, the first of its kind in the industry, this server offers a high level of scalability and cloud connectivity that is sure to go a long way in helping customers to convert their data into useful business insights. Further, this server can store terabytes of data, that can be quickly scaled to Petabytes if needed, with Cisco’s UCS manager, and unified I/O connectivity.

Another unique aspect of this server is that it consumes almost 50 percent less power than similar servers, and takes up to 60 percent less space. This is a big move considering that power consumption is one of the biggest aspects of a server’s maintenance costs, closely followed by the cost of space. By addressing both these aspects, Cisco has lowered the cost of total ownership by almost 50 percent when compared to public cloud, and at the same time, offers the perfect infrastructure to power any kind of workload. This can be particularly important for IoT and other data-driven applications, as this server can be quickly scaled to store the enormous amounts of data that is being generated every minute today. Going forward, the rate of data generation is only going to increase, and servers like UCS S3260 are expected to fill this growing demand for storage.

Through this new cloud platform and storage server, Cisco wants to provide an architecture that’ll make it easy for customers to Analyze, Simplify, Automate, and Protect (ASAP) their data, according to a press release from the company. In addition, both these announcements are sure to make it smooth and easy for businesses to make the most of their hybrid cloud adoption.

With these offerings, Cisco has made a foray into the storage business through its successful domain of server business.

A Look Into IBM’s Cloud Object Storage

IBM has set a high standard for cloud storage with its new service called Cloud Object Storage. This service allows organizations to store any amount of unstructured data on their own servers, in the cloud, or in any combination, at one of the lowest rates in the cloud storage market today.  This service will be available from October 13th, 2016 in the US, and from April 1, 2017 in Europe.

This service is built on a technology called SecureSlice that combines encryption, erasure coding, and geographical dispersal of data. Encryption is a technology where messages are encoded in such a way that only those who are authorized can view this message. Erasure coding is also a way of securing the data. This technology breaks the data down into different segments, expands them, and finally encodes them with redundant data pieces. These data fragments are then stored across different geographical locations or across different devices. This method is particularly useful to reconstruct corrupted data, and in this sense, they are a better replacement for RAID systems, as the time and overhead needed to reconstruct data is greatly reduced. Lastly, geographic dispersal of data is the method by which data is spread across different locations for greater security and redundancy. IBM acquired the SecureSlice technology when it bought a company called CleverSafe last year for $1.3 billion.

There are multiple options available for users with respect to storage. One option called Cross Regional Service, allows users to send their treated data to three separate cloud regions located in different parts of the world, while another option, called Regional Service, allows users to store in multiple data centers located within the same region. Regardless of which choice customers make, their data will be made secure and redundant with SecureSlice technology.

With this service and its many options, IBM has extended the SecureSlice technology to hybrid clouds too, thereby giving customers more flexibility and scalability, without compromising on their control over in-house infrastructure. This product comes at a time when the IDC has predicted that hybrid cloud architecture would be adopted by more than 80% of enterprises by 2018. IBM has made a strategic move by acquiring CleverSafe and extending it to a hybrid cloud environment to tap into this growing market.

In terms of cost too, this service is likely to be a good deal for customers. IBM claims that this service costs 25 percent less than Amazon Web Services S3 storage service. Also, it believes that many customers who are already using IBM’s cloud services would be willing to adopt this technology. According to Russ Kennedy, VP Product strategy, users who run apps on Amazon Web Services can also use this service to store their data, as it supports the S3 interface. The same applies to OpenStack Swift customers too, as Cloud Object Storage supports this API as well.

This service has already been deployed at a few early-adopter companies, and many more are expected to adopt it in the next few months.

Managed Cloud Storage – What’s the hold up?

Boxes on trolley in warehouseOrganisations operating in today’s highly competitive and lightning-speed world are constantly looking for new ways to deliver services to customers at reduced cost. Cloud technologies in particular are now not only being explored but are becoming widely adopted, with new Cloud Industry Forum statistics showing that 80% of UK companies are adopting cloud technology as a key part of their overall IT and business strategy.

That said, the cloud is yet to be widely accepted as the safe storage location that the industry is saying it is. There is still a great deal of apprehension, in particular from larger organisations, to entrust large volumes of data to the cloud. Indeed, for the last 20 years, storage has been defined by closed, proprietary and in many cases monolithic hardware-centric architectures, which were built for single applications, local network access, limited redundancy and highly manual operations.

Storage demands are changing

The continuous surge of data in modern society, however, now requires systems with massive scalability, local and remote accessibility, continuous uptime and great automation, with fewer resources having to manage greater capacity. The cloud is the obvious answer but there is still hesitancy.

Let’s face it though, anyone who is starting out today is unlikely to go out and buy a whole bunch of servers to deploy locally. They are much more likely to sign up for cloud-based managed services for functions like accounting, HR and expenses, and have a laptop with a big hard drive to store and share files using Gmail, Dropbox and so on. It is true to say that smaller businesses are increasingly using storage inside cloud apps, but for larger businesses, this option is not quite so simple or attractive. Many enterprises are turning to the cloud to host more and more apps but they still tend to keep the bulk of their static data on their own servers, to not only ensure safety and security but also to conduct faster analytics.

Open Door LightThe cloud storage door is only slightly ajar

With increasing data volumes and accelerated demand for scalability, you would expect many businesses to be using cloud-based managed storage already. However, the fact remains that there are still many businesses burying their heads in the sand when it comes to cloud storage. As a result, there is quite a bit of fatigue amongst the storage vendors who have been promoting cloud for some time, but not seeing the anticipated take-up. In fact, I would go so far as to say that the door the industry is pushing against is only slightly ajar.

As with most things, there are clouds and there are clouds. At the end of the day, cloud-based storage can be anything an organisation wants it to be – the devil is in the architecture. If you wanted to specify storage that incorporates encryption, a local appliance, secure high-bandwidth internet connectivity, instant access, replication, green and economical storage media – a managed cloud storage service can actually ‘do’ all of these things and indeed, is doing so for many organisations. There is take-up, just not quite as much as many storage vendors would like.

It’s all about the data

Nowadays, for most organisations it is about achieving much more than just the safe storage of data. It’s more and more common to bolt-on a range of integrated products and services to achieve a wide range of specialist goals, and it’s becoming rare that anyone wants to just store their data (they want it to work for them). Most organisations want their data to be discoverable and accessible, as well as have integrity guarantees to ensure the data will be usable in the future, automated data storage workflows and so on. Organisations want to, and need to, realise the value of their data, and are now looking at ways to capitalise on it rather than simply store it away safely.

Some organisations though, can’t use managed cloud storage for a whole raft of corporate, regulatory and geographical reasons. The on-premise alternative to a cloud solution, however, doesn’t have to be a burden on your IT, with remote management of an on-site storage deployment now a very real option. This acknowledges that storage capabilities that are specific to an industry or to an application are now complex. Add on some additional integrated functionality and it’s not something that local IT can, or wants to, deal with, manage or maintain. And who can blame them? Specialist services require a specialist managed services provider and that is where outsourcing, even if you can’t use the cloud, can add real value to your business.

What do you want to do with your data?

At the end of the day, the nature of the data you have, what you want to do with it and how you want it managed, will drive your storage direction. This includes questions around whether you have static or data that’s subject to change, whether your storage needs to be on-premise or can be in the cloud, whether you want to backup or archive your data, whether you want an accessible archive or a deep archive, whether you need it to be integrity-guaranteed or something else, long or short term. Cloud won’t always necessarily be the answer; there are trade-offs to be made and priorities to set. Critically, the storage solution you choose needs to be flexible enough to deal with these issues (and how they will shift over time) and that is the difficulty when trying to manage long-term data storage. Everything is available and you can get what you want but you need to make sure that you are moving to a managed cloud service for the right reasons.

Ever-increasing organisational data volumes will continue to relentlessly drive the data storage industry and today’s storage models need to reflect the changing nature of the way in which businesses operate. Managed storage capabilities need to be designed from the ground up to facilitate organisations in maximising the value they can get from their data and reflect how those same organisations want to access and use it both today, and more importantly, for years to come.

China Shuts Down Cloud Storage Services for Pornographic Content

“Internet companies only provide the technology to build cyberspaces for online storage, but in the end, these spaces belong to China’s online territory and, hence, fall within the government’s jurisdiction,” Qin An, a cyber security expert at the China Institute for Innovation and Development Strategy. China has defined Cloud Storage as a territory of the Chinese government and therefore has the jurisdiction to regulate the content stored within Clouds, allowing for immense censorship.

Pornographic content is widespread on cloud services, with users uploading videos and then selling them. The government believes it should take necessary action to halt this “immoral” behavior.

President Xi Jinping has ignited a moral campaign that aims to tackle corruption within the country’s sprawling administration as well as crackdown on inappropriate online content. After the National Office Against Pornographic and Illegal Publications launched a campaign in March “to address the emerging practice of sharing and hosting pornography via cloud storage services.” Many companies cloud storage services have been shut down. The list includes interne giants Sina, Tencent and Kingsoft as well as DBank and Alibaba.

Alibaba announced in March a complete closure of the service but dates have not yet been specified. Sina soon followed on April 25 with their announcement to close cloud services. DBank has become the sixth company to close or reduce operations after this crackdown. DBank will close all services and delete all data on July 1st, 2016. . Sina and Xunlei, which operate Vdisk andKuaiPan storage services respectively, announced closure of free accounts on June 30.

Homemade videos may still be created and uploaded to personal accounts as long as the content is treated as private information.

Throughout the massive crackdown, few companies, such as search engine Baidu and Internet company Qihoo360, have no plans to suspend any operations.

This is not the first of mass censorship in China, as Google Drive, Dropbox, Apple iTunes, Walt Disney’s DisneyLife services, and many online streaming shows have been blolcked in China. The Chinese government has expanded the word pornography to include any material it finds to be objectionable, such as political criticism. What will be censored next?

 

Comments:

Xie Yongjiang, deputy director of the Institute of Internet Governance and Law at the Beijing University of Posts and Telecommunications: “The government has the right to supervise and intercept illegal information spread online, while companies are also obliged to prevent such information from being uploaded online in the first place by using filtration technology.”

EMC claims it can make data centres All Flash and no downtime

EMC quantum leapAs EMC prepares for its takeover by Dell it claims it has made ‘significant changes’ to its storage portfolio, converting its primary offering to All Flash, modernising array pricings and introducing a new category of flash storage, DSSD D5 at its Quantum Leap event.

EMC’s flagship VMAX All Flash enterprise data services platform and its new DSSD D5 rack-scale flash system are part of a new drive to persuade data centres to use flash technology as their primary storage medium. The vendor claims that by 2020 all storage used for production applications will be flash-based with traditional disk relegated to the roll of bulk storage and archiving.

The new all-flash portfolio will be used by databases, analytics, server virtual machines and virtual desktop infrastructures, says EMC, which predicts that the need for predictable performance with sub-millisecond latencies will persuade data centres to make the extra investment. ENC’s new XtremIO is designed for high-end enterprise workloads, while VMAX All Flash will consolidate mixed block and file workloads that require up to 99.9999% availability, as well as rich data services, IBM mainframe and iSeries support and scalable storage growth up to four petabytes (PB) of capacity.

The DSSD D5 Rack-Scale Flash, meanwhile, is for the most performance-intensive, traditional and next-generation use cases, such as getting microsecond response times on Oracle and Hadoop based analytics jobs. Meanwhile, the new VNX Series arrays represent an entry level all-flash offering which starts at $25,000.

EMC announced that the VMAX array has been re-engineered to offer two new all-flash models: the EMC VMAX 450 and EMC VMAX 850. Both are designed to capitalise on the performance of flash and the economics of today’s latest large-capacity SSDs.

Finally, EMC also announced the DSSD D5 which, it claimed, will be a quantum leap in storage technology, with its new Rack-Scale Flash. TEMC said the new invention will be used in high production applications such as genetic sequencing calculations, fraud detection, credit card authorisation and advanced analytics.

EMC claims it will create a ten fold surge in performance levels. The storage hardware is capable latency of 100 microseconds, throughput at 100 GB/s and IOPS of up to 10 million in a 5U system. EMC DSSD D5 will be generally available in March 2016.

Public cloud spending predicted to double by 2019 with storage booming

Cloud storageThe boom in public cloud service spending will propel AWS and Microsoft into the top five of the world’s biggest storage vendors, according to analysts.

Separate reports from IDC and the 451 Group suggest that the public cloud will growth overshadow the rest of IT and change the power balance.

The latest Public Cloud Services Spending Guide from IDC predicts that global spending on public cloud services will grow at six times the rate of the rest of the IT industry. With a 19.4% compound annual growth rate (CAGR) public cloud spending will double from last year’s $70 billion to $141 billion in 2019.

The popularity of Software as a Service (SaaS) will continue as it makes up two thirds of all public cloud spending in the forecast period. However Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) will grow faster, with spending on each rising by 27.0% and 30.6% respectively.

By 2018, most software vendors will have fully shifted to a SaaS/PaaS code base, predicted Frank Gens, Chief Analyst at IDC. This means the software industry is at a tipping point where SaaS becomes the preferred option.

The industries with the largest public cloud services expenditures in 2015 were discrete manufacturing at $8.6 billion, followed by banking and professional services at $6.8 billion and $6.6 billion, respectively. Telecommunications will be the fastest-growing vertical industry over the 2014-2019 forecast period with a worldwide CAGR of 22.2%. Other industries expecting a five-year CAGRs of over 20% are the media, government, education, retail, transport and utilities.

“The cloud is the future of IT but every organisation’s journey to the cloud is different and won’t always result in moving to a public cloud,” said Mark Ebden, strategic consultant at Trustmarque. However, he warned that companies need to assess the functions that can be moved to the cloud with the least disruption.

The fast growth of public cloud service companies is already disrupting the storage market, according to a 451 Research study. It found that public cloud storage will account for 17% of enterprise storage spending by 2017, up from 8% today. In some verticals like retail the public cloud will account for 25% of total storage spending by 2017.

Public cloud will shift the IT budget so that more money is spent on storage, according to the report. In addition, Amazon Web Services and Microsoft will become top five storage vendors by 2017. While the traditional storage players like leader EMC can dominate now, in two years spending on traditional SAN and NAS products will be more muted, said the report. Dealing with data and storage capacity growth is by far the single greatest pain point for storage managers and improving backup and disaster recovery will be the top storage objectives for 2016, according to 451 analyst Simon Robinson.

HPE opens first EMEA customer engagement centre in London

HPE office logoHewlett Packard Enterprise (HPE) has unveiled a new 14,000 square foot demonstration facility next to its new offices in London’s financial district.

The new City of London-based Customer Engagement Centre (CEC) is part of a new 67,000 square foot single occupancy on Aldermanbury Square, London. The demo centre is HPE’s first in the EMEA region. The plan is to use business experts and leaders to show potential customers what HPE’s new systems and services look like and how they can be tailored to improve the client’s productivity.

HPE said it aims to prove how four key areas of expertise can help customise each service to suit every client. The four pillars of expertise are in building hybrid IT, creating a data driven culture, security and increasing productivity.

HPE’s first area of expertise, ‘Transforming to hybrid infrastructure’ will be used to help clients bridge their existing IT with cloud environments and get the best performance from their mixture of resources.

Its expertise in ‘empowering data-driven organisations’ will be applied to help companies develop analysis techniques. HPE has promised to show them how to get faster and more meaningful insights, with a view to improving decision making and customer satisfaction, and to identify new business opportunities.

The ‘protecting digital enterprises’ strand of its expertise will be used to advise companies on risk management, protection from cyber threats and sustaining operational integrity.

The fourth area of expertise, ‘enabling workplace productivity’, will be used to help clients get the best possible options for employees, customers and partners through mobile and networking solutions, said HPE.

“We see the EMEA region as one of the world’s most dynamic technological hubs and fertile environments for this revolution, hence our decision to create the first CEC outside of the US in London,” said Peter Ryan, HPE’s MD for EMEA. The UK is HPE’s second largest market.

Meanwhile HPE Ventures has invested in software defined storage provider Scality as part of an ‘enhanced partnership’ between the companies.

“The enterprise storage market is diverging into latency-optimized and capacity-driven segments,” said Manish Goel, GM for storage at HPE. “As the leader in enterprise and hyperscale servers, and the fastest growing vendor in all-flash storage with HPE 3PAR StoreServ, this Scality partnership gives us a leadership position in capacity-driven storage as well.”
