Windows Server 8 to be storage-focused OS

Microsoft executives said Windows Server 8, the beta of which is expected out in the next several weeks, is the most storage-focused OS release to date.

The new OS will support Hyper-V and SQL Server running over the Samba file sharing protocol Server Message Block (SMB) v2.2, including remote direct memory access (RDMA) over Ethernet and InfiniBand.

The new file-sharing capability allows a virtualized server infrastructure to utilize shared JBOD storage through the use of RDMA-enabled network interface cards (RNICs). To date, Microsoft has qualified one 10GbE NIC from Intel and a 10GbE and InfiniBand NIC from Mellanox Technologies.

RDMA allows servers, through special NICs, to access the memory of other servers without the use of the operating system, offering very high throughput, low latency networking for server clusters.

Jim Pinkerton, a partner architect in Microsoft's File Server Technologies development group, compared the ability to use RDMA over Ethernet or InfiniBand to that of the high-speed storage protocol Fibre Channel, in that a network interface card is used to offload network protocol traffic from a server's CPU.

"Think about going over the network for storage to get better performance, but your CPU [use] doesn't go up," said Pinkerton said.

SMB 2.2 has a multi-channel feature that enables the use of multiple physical network interfaces in an SMB 2.2 client and server. For example, Microsoft has tested a SQL database running across four 10GbE channels. Pinkerton said a SQL database his team ran achieved 6.5GB/sec total throughput or 280,000 I/Os per second using 8K writes with SMB 2.2.

Windows Server 8, which will replace Windows Server 2008, will also feature Live Migration, a tool that allows administrators to move stored copies of virtual machines from one storage server to another without taking down the virtual machine. The migration feature could allow data to be moved while a bad hard drive or array is replaced, or it could be used for SAN upgrades or just to migrate data from one storage platform to another.

Pinkerton said the Live Migration upgrade will also remove downtime on Patch Tuesdays by allowing admins to migrate virtual machines and applications onto another server node, upgrade the original server and then migrate the applications back.

Additionally, Windows operations such as Check Disk or Check Sum can be used to prepopulate a list of data errors -- in a database, for example -- without having to take a server or application offline, Pinkerson said.

Windows Server 8 allows admins to take a snapshot of data to create a list of errors that can then be used to take a volume offline only long enough to correct the data problems.

"The time to perform Check Disk today is proportionate to the number of files in a storage system. So if you want to check 100 million files, you have to take the whole cluster off line to check it, and that could take hours or days," Pinkerson said. "That operation can now be measured in seconds."

Additional management tools will allow adminstrators to oversee up to 200 hard drives or SSDs, allowing the disks to be seen as a single pool of capacity that can be carved up into logial unit numbers (LUNs) and volumes to be shared among physical servers.

"It's a lot harder to find guys to mange a Fibre Channel fabric than an Ethernet fabric. A lot of this stuff becomes more self service or doable by people in the data center," said SW Worth, a senior program manager at Microsoft.

Data deduplication and thin provisioning, or the ability to expand storage volumes on an as-needed basis, is also native to Windows Server 8. "Think of us as a new entry in the enterprise storage space. We're competing for some of that business," Worth said.

"The path we're going down is file-based access, so you don't need storage rocket scientists to administer your environment. And, we're also using SSDs to get performance without having to tune the disks," Pinkerton said, referring to the practice of short-stroking Fibre Channel hard drives to achieve peak performance, which also greatly reduces available storage capacity.

Microsoft also upgraded its access list control (ALC) to enable users to specify who can read and write to documents based on their business unit or the sensitivity of the data itself. For example, documents can be classified as business critical, as containing personal employee data, or they can be classified by business, such as legal, finance or marketing.

Pinkerton said Windows Server 8 will help companies with regulatory compliance and civil litigation by offering document classification.

Google, Motorola must capitalize on regulatory win to battle Apple's iPad

The US Department of Justice and European Commission have okayed Google’s planned $12.5 billion acquisition of Motorola Mobility. Now the two have to work together — and fast — to being Android 4.0 to Motorola’s Xoom and XyBoard and whatever other Android tablet platform that can grab some share against Apple’s iPad.

Best Microsoft MCTS Certification, Microsoft MCITP Training at certkingdom.com

Governmental clearance of Google’s $12.5 billion purchase of Motorola Mobility — both here and across the pond — is no doubt a big win for the open source Android operating system. But it’s no slam dunk.

Google and its new hardware device arm must get more serious in the tablet wars. Unlike Motorola’s roster of Android-based smartphones, Motorola’s Xoom tablet has competed poorly against Apple’s iPad.

And iPad 3 is getting set to debut.

Motorola won’t say exactly when Xoom will get Google’s Android 4.0 update, also known as Ice Cream Sandwich. A spokesman for Verizon confirmed that all of these devices are expected to get the update — Droid Bionic, Droid Razr, HTC Rezound, Spectrum by LG, Droid Xyboard, Motorola Xoom and Droid 4 — but he doesn’t known when.

Motorola, for its part, has said it is working to deliver the ICS upgrade for DROID RAZR and Motorola RAZR in the first half of 2012.

The Xoom? Xyboard? So far, nada news on those releases.

This is all Motorola Mobility has said:

”We are planning to upgrade DROID RAZR™ by Motorola, Motorola RAZR™, Motorola XOOM™ (including MOTOROLA XOOM™ Family Edition) and DROID BIONIC™ by Motorola to Ice Cream Sandwich. We will provide more precise guidance on timing after post-public push of Ice Cream Sandwich by Google, as well as any possible additions to this list of devices.”

Now that the US Department of Justice and European Commission have okayed the deal, Google and Motorola need to act fast.

First, Google must be careful not to stifle tablet innovation by restricting or delaying access to ANY Android 4.0 code to Motorola Mobility’s rivals. Heck, Samsung beat everyone to the punch.

That being said, ICS is a big deal and Motorola — with Google’s supercharged backing — ought to get something out the door fast. Really fast.

Young generations of users — my four-year-old included – are already adept at the iPad in a Droid heavy home. Google could lose the tablet war — and the smartphone war, for that matter — if the resulting merger slows down the Android product delivery cycle.

“Ice Cream Sandwich brings an entirely new look and feel to Android. It has a redesigned user interface with improved multi-tasking, notifications, Wi-Fi hotspot, NFC support and a full web browsing experience. With Ice Cream Sandwich, Android has been rethought and redesigned to be simple, beautiful and useful,” noted David Rothschild, a senior vice president of software and services at Motorola Mobility, which spun off from Motorola last year. “ Ice Cream Sandwich introduces innovations such as Face Unlock to unlock your phone, a Data Manager to control your network data usage, and advanced multimedia and imaging features. Ice Cream Sandwich also provides developers with new APIs, unified U.I for phones and Tablets, and improved performance by enabling developers to leverage hardware graphic acceleration.”

Great. So let’s get moving, Google and Motorola. You’ve got the platform, the patents, the legal clearance and the innovation. But don’t let the bureaucracy and legalities of a merger blow your windows of opportunity. Time could be slipping on the tablet front.

Educators Deal with Relationship between the PowerPoint Teaching and Traditional Teaching

PowerPoint courseware as an auxiliary teaching software, it should be used to reach teaching purpose for the purpose, should avoid the heavy form light content of unhealthy phenomenon. The form is for servicing content, should according to the teaching contents to design PPT courseware. In the application of multimedia courseware, should according to the teaching contents to optimize design, and on the performance forms the cognitive law with students. If the main energy in the form of teaching, and the result is a new class, and actual effect is go light. Only enrich the content and the form of perfect combination, can we truly achieve the instruction knowledge, to mobilize students' enthusiasm, improve the teaching environment purpose.

Courseware design should notice the feedback. Scientific teaching design requires teachers to pay attention to how to teach, more emphasis on the students how to learn. Therefore, the teacher in the courseware design's process, should bring into full play the multimedia feedback accurate, timely characteristic, making courseware has the function of the students study tracking, so that teachers get effective feedback information, and thus more rationally adjust the teaching program.


PowerPoint multimedia is using a computer to text, images, graphics, animation, audio, video and so on many kinds of information of the integrated treatment of the computer application technology, using PPT PowerPoint multimedia work to the education, the more it is beneficial to the development of new modern education. Our education as a basis of education workers on a line, is also in constant exploration to the modern PowerPoint multimedia education role in promoting, and gradually improve the auxiliary PowerPoint multimedia teaching means, for the foundation education of modern development offer an own strength. The junior high school is combined with information technology to talk about my PowerPoint multimedia assisted teaching advantages to the understanding of the use of PowerPoint multimedia teaching, and the problems and countermeasures, but when use the PowerPoint for teaching, when making PPT slideshow, we can also convert PowerPoint to video files and play it automatically.


Using PowerPoint multimedia teaching can increase the capacity of teaching and improve teaching efficiency.

Use PPT, students still have to take notes, should understand that the benefits of lecture notes written, the teacher can also agreed with the students, each chapter PPT to made this chapter to copy homework to them. Be like again, combined PPT and blackboard writing, bring their own advantages; Use PPT the document "from the definition animation" change "click the button jumped out of a whole page" situation, so that the students don't scare, don't lose the confidence of the written down; Use "links" and the header and tip the context. Using PPT, understanding should guide students to make notes, a way will grope out.

The PowerPoint multimedia teaching can quickly put the curriculum resources appeared in front of the student, which can save a lot of time, teaching blackboard writing, and can make the teacher teach more knowledge, to a certain extent, increased the capacity of the class, and can obtain a better teaching effect. For example: teach the history of computers ", "the world's first computer", "four generation computer" and "super computer" three content with PowerPoint slides made both texts, class, the teacher in computers and projector and other PowerPoint multimedia equipment in the slides explain to the content of the projection screen timely, students directly from the screen for more comprehensive, intuitive knowledge, this increases the capacity of classroom teaching, improve teaching efficiency, also aroused the enthusiasm of student's study.

ppt teaching

In the PowerPoint multimedia assisted teaching, accurately grasp the use of PowerPoint multimedia of good opportunity, deal with a lot of media and blackboard, the chalk, ordinary teaching apparatus, language expression and the relationship between the traditional teaching method, want to have the appropriate lectures, blackboard writing, the teachers and students interact and reflection learning process. In the application of PowerPoint multimedia courseware, want to consider how to give full play to the comprehensive the combination of a variety of media function, the flexibility to call figure, words, sound, like with the teaching information, and to strengthen the man-machine interaction between function, stimulate students' thirst for knowledge, the students' attention to the teaching content come up, deepen understanding of knowledge and master, in order to get the best teaching effect.

PowerPoint multimedia teaching is the traditional teaching foundation increased the special tools of the PowerPoint multimedia teaching; it can't give up all of the traditional teaching method. Therefore, the use of PowerPoint multimedia teaching assistant first is to understand this class to use the PowerPoint multimedia purpose; The use of PowerPoint multimedia courseware can let the student teaching content more easy to understand and master; Still need to adopt what traditional teaching method combined. Then, according to the teaching contents and teaching aim, teaching object characteristics of elaborate design the PowerPoint multimedia teaching process. Why need to convert PDF to PowerPoint? Microsoft PowerPoint slides are frequently used in presentations as a reference point for the speaker. While pages in a PDF file may be relevant to use in a PPT presentation, the original source material might not be available. Now you can easily create PowerPoint to flash files with a PDF to PowerPoint Converter software's help.

PowerPoint multimedia applications in the basic education teaching, can make the effect of classroom teaching and the teaching quality be remarkably improved, but also make the main part of college students get a greater degree of the play, but when use PPT PowerPoint multimedia, there are also some undeniable problems. To recognize and timely paid attention to the problems in the teaching practice, and can play PPT PowerPoint multimedia huge advantage, make PowerPoint multimedia work better for teaching services.

Alcatel-Lucent reports rising profit on falling revenue

Telecommunication equipment maker Alcatel-Lucent reported a profit for the fourth quarter, but revenue fell 12.9 percent year-on-year as the company continues to face a challenging market, it said on Friday.

The company reported sales of a 4.15 billion euros (US$5.37 billion), and a net profit of a 868 million euros, compared to a net profit of a 340 million euros a year earlier.

Revenue was down across Alcatel-Lucent's different divisions; the wireless division fared the worst with a 22.8 percent drop. The only exception was the enterprise division, which grew its revenue 0.3 percent.

The company also reported a full-year net profit for the first time since the merger of Alcatel and Lucent Technologies in 2006. Cost-cutting has played a big role in helping Alcatel-Lucent return to profit, and next year the company plans to cut an additional a!500 million in costs.

Like many vendors, Alcatel-Lucent hopes patent licensing will help increase its revenues. On Friday, the company announced a patent syndication deal with patent licensing company RPX, which also counts technology companies Avaya, Ericsson and Nikon among its clients. Alcatel-Lucent will still retain the ownership of its 29,000 patents -- which cover areas such as wireless, semiconductors, optical, cloud computing and network security.

But just because Alcatel-Lucent is making a profit doesn't mean the company is out of the woods. Overall, the fourth quarter last year was a tough one for the telecommunication equipment makers.

In November, Nokia Siemens Networks said it is planning to cut 17,000 jobs worldwide as it aims to cut a!1 billion from its annual costs by the end of 2013, while Ericsson's profits dropped by 66 percent year-on-year.

Alcatel-Lucent's goal for 2012 is to achieve a higher operating margin that in 2011.

Bluetooth in Brief

Bluetooth is a radio or wireless technology designed for short range data communications in the Industrial, Scientific and Medical (ISM) band. The frequency range is from 2.402Ghz to 2.480Ghz, with the available frequency sprectrum being broken up into 79 x 1Mhz wide bands.
Bluetooth was designed by Ericsson as a short range wireless connectivity solution and is used to build Personal Area Networks, or PANs as they are known so that devices in close proximity can pass information. Typical examples being a mobile phone downloading data to a Personal Computer or a mobile phone earpiece communicating with the phone itself.

The technology behind Bluetooth is known as FHSS (Frequency Hopped Spread Spectrum), where the datastream is broken up into small pieces, each containing several binary bits of data which are transmitted in a pseudo random sequence over a series of up to 79 frequency bands. As Bluetooth has developed and matured, a number of data modulation schemes have been used to modulate the data onto the radio carriers including GFSK (Gaussian Frequency Shift Keying), DQPSK (Differential Quadrature Phase Shift Keying) and 8DPSK (8-ary Differential Phase Shift Keying). The development and use of the different modulation schemes were an attempt to increase the data rates of the system.
So how does Bluetooth operate?
Two or more Bluetooth devices that establish a connection (and share a channel) form a small wireless network known as a Piconet, with up to eight devices, forming the piconet . One device becomes the Master station, can join a Bluetooth piconet. Normally the device which initiates the connection will be the Master and other devices joining the PAN will be slaves. The master passes a Frequency Hopping Synchronisation (FHS) packet to any slaves containing its address and clock. The address of the Master Bluetooth device is used to determine the hop sequence and all slaves use the Master Clock to determine which frequency to transmit or receive on at any given time.
A group of piconets are referred to as a Scatternet, with each individual piconet having a unique hopping sequence, determined by it’s Master’s address. If a collision occurs where two devices transmit on the same frequency, a device will just retransmit the data on the next frequency hop. Although this can ultimately affect the performance and data rate of the transmission, it is the accepted method, just like collisions are a way of life in a shared Ethernet network when a hub is in use.
Devices can be a member of multiple piconets by using each Master address to determine the hopping sequence for each network, but can only be the Master for one piconet. The access method used by Bluetooth devices is known as TDD (Time-Division Duplex) where each device (Master and Slave) share the same frequency and are allocated a timeslot during which to transmit. A master will normally use even-numbered time slots and the slave will use odd numbered timeslots.
There are two types of transmission links normally supported by Bluetooth, known as SCO (Synchronous Connection-Orientated) and ACL (Asynchronous Connectionless Link). General Bluetooth operation uses ACL, where the packet and payload length will determine how many timeslots are required. Because ACL is Connection-Orientated, packets that are not acknowledged will be automatically retransmitted, abeit on a different timeslot or timeslots. Forward error correction can be employed as an option and although the data delivery may be more reliable, the data rate will reduce accordingly depending on how error prone the environment is at the time.
Voice over Bluetooth normally used an SCO link, where the voice data is sent over a number of reserved timeslots within an already established ACL link. Retransmissions do not occur on an SCO link as this could cause a number of problems, least of all latency and jitter. However, forward error correction can be used to provide a degree of reliability. There is an Enhanced version of SCO that can employ retransmission in some circumstances.
The latest version of Bluetooth, version 4 and all previous versions of Bluetooth have been designed to be backward compatible with previous versions, so no worry about using older devices with the newer Bluetooth devices.
The Bluetooth technologies have allowed us to provide fast data communications between devices that are in close proximity (within a few metres) without the need for a cable running RS-232 protocol for example and so have provided us with mobility free from the constraints imposed with the use of copper wiring.
