VMWare training courses

  • What is VMware?

    31 October 2011

    VMware are the global leaders in cloud infrastructure and virtualisation solutions – systems which can save companies’ time and money by reducing IT complexity.

    With VMware software, different virtual machines can run different operating systems and multiple applications on the same physical computer. In short VMware software lets you run multiple virtual hardware on one guest operating system.

    These multiple desktops look and feel like a physical computer and have the same operational capabilities. For this reason, these virtual machines are highly portable between computers, because every ‘host’ looks nearly identical to the guest. In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer and there resume activity exactly at the point of suspension. This offers numerous working advantages, with users able to log-in to their ‘desktops’ and access documents and data from any host server.

    VMware allows you to install, run and manage automated configuration tasks. vSphere is a suite of tools including VMware ESX and the latest version ESXi. These enterprise-level computer virtualization products are used by large businesses and organisations and provide business-orientated tools such as automated billing systems, content management, CRM and HR management.

    The VMware courses offered by Total Training Solutions cover installation, configuration and management of the various VMware programs. They vary from specialised and dedicated areas of cloud computing and virtualisation, such as vCenter Server and vSphere Management Assistant, vCenter Converter and ESX/ESXi to a complete ‘fast-track’ package, covering all aspects of VMware systems.

  • VMware: What’s New for 2012?

    07 November 2011

    For years VMware has benefited as businesses invest in data centres to run software in the so- called cloud, or stored on the Internet instead of their own server computers. However the company face a tough trading environment in 2012 with the likes of Microsoft now offering free virtualisation. To counter this, VMware has a number of programme and software updates planned for launch in the New Year, namely vSphere 5.0.

    New features of vSphere 5.0 will include VMware vCenter Server 5.0 and VMware ESXi 5.0. Current VCP4’s will be expected to upgrade their qualifications to version 5.0 and learn to install VMware vSphere and upgrade from vSphere 4.x to vSphere 5.0, the first version of vSphere to include only the ESXi hypervisor.

    New Infrastructure Services of vSphere 5.0 include:
    vSphere ESXi convergence – enables vSphere users to leverage thinner architecture, a more secure footprint and streamlined patching and set-up model.

    New virtual-machine format (Version 8) – features include support for 3D graphics for Windows Aero and USB 3.0. devices.

    vSphere Storage I/O Control
    – improve management and enforcement of service-level agreements (SLA’s) through extensions of limits and shares in Network File System (NFS) datastores.

    vSphere Distributed Switch
    - Improves visibility of virtual-machine traffic through NetFlow and enhances monitoring and troubleshooting through Switched Port Analyzer (SPAN) and the Linked Layer Discovery Protocol (LLDP) support.

    New Application Services include:
    vSphere High Ability
    – new architecture enables superior guarantees, simplified setup and configuration and expanded scalability.

    ESXi Firewall
    – New service orientated and stateless firewall engine restricts access to specific service by IP address or subnet. This is particularly useful for third party components that require network access.

    New Management Services include:
    VMware vCenter Server Appliance – Run vCenter Server as a Linux-based virtual appliance.

  • VMware: Thin Client vs. Zero Client

    14 November 2011

    Thin clients and zero clients are virtual desktop infrastructures (VDI). A key driver for companies adopting this type of technology is the promise of radically lowering Total Cost of Ownership (TCO) while still delivering a complete Windows-based desktop computing environment. Your choice of endpoint will greatly influence this success. Here we will discuss the key points of thin client and zero client options.

    The term thin client refers to a computer or program which heavily depends on some other computer, or more specifically its server, to fulfil its traditional computational role. Thin clients occur as components of a broader computer infrastructure, where many clients share their workings with the same server.

    A common modern thin client is a low-end computer terminal which concentrates solely on providing a graphical user interface to the end user. The remaining functionality, in particular the operating system (OS), is provided by the server. Thin clients can be designed with much more modest hardware, because they perform much more modest operations, thus saving businesses and organisations money on their I.T. spend. Other benefits include the security risk factor which thin clients go towards combating. A thin client relies on its server to process most or all of its business logic thus removing security risks in individual hosts. Other facts to consider with this type of technology include the impact on productivity and energy use from endpoints.

    Zero client technology is also a server-based computer model but the end user's computing device has no local storage, no operating system, central processing unit (CPU) or memory located at the endpoint. Zero clients all have software and all run an OS. For this reason a zero client can be contrasted with a thin client, which retains the operating system and each device's specific configuration settings in flash memory.

    A zero client device is a small box that only connects a monitor and its accessories (keyboard, mouse etc) back to a remote server. The server, which hosts the client's OS and software applications, can be accessed wirelessly or with cable. Zero clients are often used in a VDI environment.

    This is what separates zero clients from thin clients (which require local processing capabilities and operating systems). In fact, some say that zero clients, thin clients and VDI are different technologies that can intertwine to create a desktop experience for the end user.

    VDI is the key technology behind zero clients. Ideally a zero client endpoint will connect back to a virtual PC located on a blade server in the data centre.

    In summary:
    • A Zero Client is more likely to be a purpose built hardware, designed specifically to connect you to your virtual desktop.
    • A Thin Client is a more generic device which could be used and programmed to run different functions/software other than just connecting to a virtual desktop.

    VMware adopt VDI technologies into their programs and software. VMware courses offered by Total Training Solutions include modules in VDI programming and configuration, such as the vSphere Install Configure Manage course.

  • VMware View & vSphere – Performance & Best Practices

    21 November 2011

    Performance Improvements in View 5:

    PCoIP protocol improvements
    Optimizations to the PCoIP protocol benefit users in almost all usage scenarios.

    Bandwidth Optimization
    VMware View 5 offers major efficiency improvements in the WAN environment where bandwidth is highly shared. This is especially impressive as it does so whilst maintaining the user experience. In a typical office user, bandwidth consumption is reduced by up to 75%. This significant improvement means the VDI can support 4x more users to the same network. Even with new caching and lossless codec features, overall guest CPU usage is reduced.

    Compute Optimization
    Idle CPU usage is improved. Whereas once when a screen had loaded, a machine can lie dormant for varying periods of time whilst a user reads a page, VMware View 5 reduces the amount of overhead background activity and bandwidth used in this ’downtime’. Image processing and compressor functions have been reviewed, their coding altered for efficiency and implementation further optimized.
    With View 5, PCoIP Protocol has been optimized to take greater advantage of the SSE SIMD support. This SIMD acceleration not only provides an expanding coverage of the code base but also applies the SSE instructions on the latest processors.*

    Platform improvements with VMware vSphere 5
    CPU scheduler
    CPU and memory optimizations in vSphere 5 help achieve a higher consolidation ratio, particularly when using Windows 7 as this uses more memory than Windows XP.
    VMware vSphere 5 has scheduler optimizations and works by making efficient use of the CPU. It does this by optimally scheduling the different desktops on the hyper-threaded core, meaning all thin (and zero) clients run in parallel whilst performing multiple tasks.

    Memory footprint reduction
    Memory on demand and swap mechanism lets more of the guest VRAM stay in the main memory. 60% footprint reduction = better consolidation rate.

    Conservative ballooning
    In earlier versions, the balloon driver activated when the systems free memory dropped below 6% of the total memory. On servers with a large amount of main memory, 6% is a lot and ballooning is not required. vSphere 5 keeps the 6% threshold for machines with less memory but also allows ballooning at as low as 1% for larger machine memories.

    vSphere 5 also reduces the amount of virtual machine book-keeping data that needs to be kept in the main memory, making more memory available for desktop VRAM and improving VDI.

    The full functions, workings and improvements of VMware View and vSphere can be learned through professional training course such as those offered at Total Training Solutions. Ranging from beginner to more advanced best practices modules, call the TTS team on 0800 612 1299 or email info@tts-uk.com to discuss the course that is right for you.

  • VMware release ESXi - for free!

    29 November 2011

    VMware ESXi revolutionised the virtualisation solutions market when it was first introduced. The benefits of an embedded hypervisor which could support multiple virtual machines simultaneously meant a real solution from the desktop to the data centre. This technology is now available at no cost to help companies of all sizes experience the benefits of virtualisation.

    VMware ESXi offers a highly integrated service and isolated function blocks within the system to communicate more effectively. The need for real-time performance is also addressed as well as providing a resource-constrained target environment and with the industry’s smallest footprint and OS independence, ESXi sets the bar for security and reliability. It’s no wonder the leading server manufacturers have all embedded VMware ESXi.

    The fact that this software is now freely available offers a more flexible service to organisations looking for a virtualisation solution. Even start-up and SME businesses can take advantage of this technology from the offset, enabling them to run a much smoother I.T. operation.

    Gartner Vice President Distinguished Analyst Tom Bittman believes the hypervisor itself is really just a foundation. He says, “The business model and real value in virtualization is evolving toward a virtualized infrastructure and the management and automation tools leveraging the hypervisor.” Raghu Raghuram, Vice President of Products and Solutions at VMware echoes these thoughts, “ESXi is mature enough and easy enough to use that it can be the entry point into virtualization for those companies just taking their first steps with the technology” he says.

    The performance improvements in virtualisation software mean there are no longer any hurdles to 100% virtualisation and the move by VMware to make ESXi freely available removes the financial hurdles as well.

    There are some drawbacks of the free version however, specifically when upgrading from ESXi 4 to ESXi 5, including the lack of access to the more robust vSphere Update Manager (which makes upgrading very easy). There have also been complaints about the meagre 8-GB vRAM allotment for the free version of ESXi. There are also some constraints as to the hardware the free version can run on. VMware has a hardware-compatibility list that you should adhere to when buying or building a virtualization host server if you plan to use ESXi; if VMware ESXi doesn't have a driver for certain hardware in the host system, it may function poorly or not at all.

    To learn more about VMware ESXi, including how to install, configure and manage the software a professional course offered by Total Training Solutions is advised. Browse our course directory then call 0800 612 1299 or email info@tts-uk.com to book your place.

  • What is VSphere?

    05 December 2013

    Total Training Solutions offer a range of courses in VMware, and more specifically VSphere. The recent release of VSphere 5.5 has reignited interest in the system and its capabilities. But what exactly is VSphere and how could it be beneficial for your business?

    VSphere is a virtualisation platform, allowing you to run multiple virtual machines on a single piece of hardware. These virtual machines can then run Windows, OS X, Linux, etc, regardless of the hardware manufacturer. VSphere offers these virtualisation capabilities on a grand scale, created specifically for cloud computing, making it a perfect system for larger teams. So why could this be useful for you or your business or organisation?

    In today’s society, where any successful business relies on computers and networking, most organisations will already have multiple servers running simultaneously, each on its own piece of hardware. However, the chances are that most of these machines are not being used to their full potential. Through making the most of the capabilities of each piece of hardware, Vsphere can result in lower maintenance costs for hardware, greater energy and cost efficiency, and easier expandability.

    In this difficult financial time, many organisations and businesses are trying to increase efficiency in any way possible. An investment in a course such as VSphere can actually save you money in the long run. We offer a number of courses centred around VMware and VSphere, including classes on installing, configuring and managing the system, overviews for those new to the system, and fast-track courses for both version 4.0 and 5.0.

    VSphere is the world’s leading virtualisation platform for building cloud infrastructures - if, like thousands of others, you too feel that you or your employees could benefit from training in VSphere, give Total Training Solutions a call. We can suggest which course would be perfect for you, and in only a matter of days, you too could have a certification in VSphere. Due to the popularity of the system, your skills are sure to be transferable, and may even give you an edge over competitors when job-hunting.

  • The benefits of virtualisation

    10 December 2013

    Those who are new to the idea of virtualisation may be confused as to why they would need it - what it contributes to the workplace, and in what way it could be advantageous for a company or organisation. There are multiple benefits to virtualisation and to a subsequent cloud computing system such as VSphere, but we believe these five are the most convincing reasons to switch to a virtualisation system…

    1) Virtualisation is eco friendly. Consolidating multiple virtual machines onto fewer physical servers means less power is needed - resulting in a smaller energy footprint. Less physical equipment is also needed, meaning less money needs to be spent, and nothing is wasted.
    2) A lot of money often goes into hardware so through reducing the amount of hardware being used, less needs to be spent. This saving also extends to electricity, maintenance and space costs.
    3) Less heat generated. All servers generate heat which can often cause multiple problems including software not functioning properly and fans breaking due to overuse. By reducing the number of servers through virtualisation, less heat is generated in the data centre, making heat-related problems much less likely.
    4) In the event of a disaster, virtualisation makes fixing it a much faster and smoother process. It also reduces the redeploy time should a physical server die. With virtualisation, you’re not reliant on having a backup server ready or having up to date data on that server - you will be up and running again in minutes.
    5) You’re not tied down to one software vendor. Have a PC but prefer OS X? Not a problem. This allows for much more flexibility and customisation.

    The main thing an organisation takes away from virtualisation is efficiency. Through using hardware to its maximum capability, less money is wasted and you know you’re not wasting any of your machines. Any system which can save a company time, money and energy is a valuable one, which is why virtualisation has been such a game-changer in IT.

    TTS offer a number of courses in VMWare, so you too can benefit from this technology. We also have a range of VSphere courses, including the new VSphere 5.5, for total cloud computing efficiency.

  • What's new with VSphere 5.5?

    19 December 2013

    VMware is the market leader when it comes to virtualisation, so it comes as no surprise that the release of vSphere 5.5 has been something of a game-changer. But what’s new to vSphere 5.5 and why could your company benefit from training in this state of the art technology? These are just a handful of the updates to 5.5:

    • Doubled Host-Level Configuration Maximums
    • Improved Power Management
    • Hot-pluggable PCIe SSD Devices
    • Graphics Acceleration for Linux Guests
    • vCenter Single Sign-On (SSO)
    • vSphere App HA
    • vSphere Flash Read Cache
    • Traffic Filtering Enhancements
    • Enhanced Host-Level Packet Capture

    Many of the enhancements and updates to the vSphere system have been put into place as a response to real customer feedback, requests and complaints. For this reason, vSphere 5.5 is arguably the most user-friendly and intuitive vSphere edition to date. And with the new year fast approaching, what better time to invest in vSphere training for your organisation?

    vSphere ensures maximum efficiency in your data centre - both in terms of cost and energy. Reducing the amount of hardware that is being wasted and underused, and in turn, reducing the amount of hardware required, lowers outgoing costs spent on maintenance and repairs. It’s also environmentally friendly, reducing your company or organisation’s energy footprint. And due to the usability of 5.5, you can be safe in the knowledge that you’ll be getting training in the most cutting edge and efficient virtualisation product on the market.

    Whether the training is for yourself in order to get vSphere 5.5 up and running in your organisation or to introduce your colleagues and employees to the system, give Total Training Solutions a call. We have a range of courses available for most vSphere systems, including the brand new 5.5, so check out our course directory to see which one feels right for you and your business. Give us a call on 0800 612 1299 or contact us via our website if you have any questions or queries - we’d be happy to help.

  • Which vSphere 5.5 course is right for me?

    27 December 2013

    So - you have decided to invest in a vSphere 5.5 certification. But which one is right for you? The two courses we offer which specifically focus on vSphere 5.5 are the Install, Configure and Manage course and the What’s New course.

    What’s New 5.5 explores the new features and upgraded elements of the latest version of vSphere. This course is recommended to those upgrading from 4.0 or 4.1 to 5.5 as it gives a thorough overview of not only the changes made to the most recent version, but also the differences between the 4.x and 5.x versions of vSphere. The two day course aims to educate trainees in all the main functions of vSphere 5.5 and give them the skills to be able to utilise them. Ideal candidates for the qualification are system administrators, IT managers, system architects (all at a professional level) and anyone responsible for implementing or managing vSphere environments. Over a two day period, this professional qualification will give participants the skills to be able to implement all they learn about 5.5 in their work environment and improve the efficiency of an organisation.

    Install, Configure, Manage 5.5, unlike What’s New, does not require a qualified knowledge of an earlier vSphere system - just administration experience on a Microsoft or Linux operating system and an understanding of the concepts presented in the VMware Data Center Virtualization Fundamentals course. Therefore, if you’re installing vSphere for the first time using 5.5, this could be the course for you. The course is targeted at system administrators, system engineers and operators of ESXi and vCenter Server, and aims to educate trainees in the functions of vSphere 5.5. By the end of the five day course, those qualified will be able to successfully install and manage vSphere 5.5, even without prior vSphere experience.

    Whichever course you feel is right for you, Total Training Solutions have you covered. We offer only the most professional and respected qualifications, for an affordable price, so you know that you’re getting an expert education and that your hard work will be recognised. Take a look at our full range of vSphere courses or alternatively, visit our course directory for our entire catalogue. If you have any questions about vSphere courses or to discuss your options, give us a call on 0800 612 1299 or visit our contact page.
