Disposable servers are coming
Duff server? Just clone another one.
| |
|
Help at hand. |
Using drag-n-drop to copy a server's contents to another virtualised server - while running live - and mark the old one as duff, is becoming as easy as managing files in Windows Explorer. A taste of computing to come? Massive data centres coming online now are making this kind of manipulation feasible and almost trivial, but the nascent computing sea change is growing from a whole array of features in the most common of operating systems such as Windows. Windows 7 launched in October and has proved a hit with testing labs in that, not only does it run on hardware that runs Vista, it can often run faster too. Existing applications and software should make the transition seamlessly, except for those that operate at binary levels, such anti-virus and firewalls, so it's worth checking for compatibility and newer versions.
Among Windows 7 benefits are the fact that its designed to go hand in hand with recently released Windows Server 2008 R2. But delve further and we see how key new features ease wide area networking and secure connections to outlying offices.
Some of these features may only be available in Ultimate editions of Windows 7. Windows Server 2008 R2
Efficiency is the new old buzzword for this R2 edition of Windows Server 2008, with an emphasis on helping server farms and data centres. Don't forget, if you have 2 servers in your office, you already effectively own a data centre! Windows Server 2008 R2 provides Client and Server virtualisation through Hyper-V and Presentation virtualisation through Remote Desktop Services (an embedded Terminal Server). Hyper-V has been improved and permits for instant fail-overs - cutting over to a new server before the current one fails
In the future, we won't all be wearing shiny clothes – as promised by a myriad sci-fi writers - but we will be storing much of our data in massive data centres. Really, really big data centresYou can now buy processor cores like apples, by the container-load. In the last 12 months Amazon has already abandoned one computing facility in Oregon only to begin another in North Virginia, adding to its raft of facilities in the US and a handful of European cities.
Google, necessarily a long time player in the data centre market, unveiled its surprisingly simple secrets for server power support mechanisms, as bundled into thousand-strong containerised server packs. Even Apple, a surprise contender in the data centre arena, admitted to building a North Carolina facility of some 500,000 square feet (46,000 sq metres). Imagine this huge space equivalent to walking 6Km along one side, then 8Km along the other. Billed simply as the company’s East coast data hub, current speculation is that Apple may be scaling up capacity for future cloud computing ambitions.
System X, an Xserve G5 supercomputing cluster CC-licensed pic by Christopher Bowns Such projects now reach well into billions of dollars, an undertaking of which Microsoft is only too aware as it invests in its new European Data Centre in Dublin - the size of 8 football pitches – as part of its move towards Azure, its cloud computing solution. Supplying literally millions of users, these batteries of servers are mounted in shipping-size containers, with no space for human access. If a server dies, it's just replicated and marked like a bad block on a disc. When too many units in a container become unusable, the whole container is simply replaced. Massive benefitsWhat are the benefits of these Borg-esque structures for people who actually buy into them? Instant scalability (essential for companies that merge or buy others), automatic updates of operating systems, high availability with proper Service level Agreements (SLAs) and penalties when downtime occurs, ability to support a whole range of applications and operating systems, portability of existing applications, and low costs because massive scale means smaller environmental impact per server.
Cloud computing eases DR and migrationWith virtualisation on hand, being online continuously for users becomes much easier. Let's take two examples. Disaster recovery: How do you know your DR strategy works? No longer do you have to invest in physical hardware and spend a whole weekend testing data recovery. In a few minutes, a new virtual server can be cloned, then tested for DR without disturbing the live server(s). Suddenly DR tests really can be done quarterly or monthly as your strategy demands, instead of it being theory. Migration: Got 100 users to migrate from one creaking server to another? No sudden downtime necessary while users are migrated en masse. Clone a server, test a few key power users by migrating them to the clone, then run both servers live, gradually migrating users in blocks until the old server can be decommissioned. Pay-as-you-go serversFor everyday clients in need of a virtual server, the commitment can be small by eliminating the purchase factor altogether. Resellers can either sell server access on a pay as you go basis or longer contract or clients can deal direct with server suppliers or an Azure cloud partner. There will be service fees to manage each client's part of an Azure cloud, but the lack of commitment to capital expenditure makes it very attractive to investors, funders and accountants who prefer the more predictable operating expenditure. If you haven't seen articles littered with "CAPEX vs. OPEX" lately, IT costs obviously don't register on your horizon. For small networks, the costs will be similar to an in-house network, but large e-commerce enterprises will see savings of up to 70% on conventional IT infrastructures or hosting. In 5 years, such trends could mark big changes in the traditional server model with the large scale implementations bringing costs down further. Many of these large scale developments have been driven by environmental awareness and have come to fruition at a rather fortuitous time when economic downturn is forcing organisations to think about getting IT costs down. There's a lot here to comprehend, and more that is still to come. If you want to avoid being hit with a tidal wave of technology and just have a chat to get to grips with some of it, use the follow up form below. -IB- Acknowledgements: staff team |

Don't let ISP downtime derail your mail
An office without email can induce train-wreck style panic if there's no sign of services returning to normal. But it doesn't have to be like this.
| |
|
Help at hand. |
Most organisations have email routed via their broadband Internet Service Provider (ISP), or perhaps one dedicated for the purpose. The trouble is that email has become a 24x7 addiction, so that its loss, however temporary, suddenly becomes an organisation's entire focus, to the detriment of all other work. When all your employees are just sitting around wringing their hands instead of writing reports, such frustration is expensive.
Rusty Siding vs. Fast TrackThe scenario above is the technical equivalent of shunting trains into a dead end siding while you wait until a track is repaired. What if you could re-route trains on to say, Track 2 via a set of points, to avoid repairs on Track 1, and then switch back again when repairs are done? Well the good news is that it is possible, and in fact increasingly common, these days to redirect your mail automatically to another mail server for those rare but crucial moments when mail providers do maintenance or generally 'throw a wobbly'. No more DIY email routingTechies have been to do this for some while of course, by 'fiddling about' with MX records, but skill and testing are required to make the ad-hoc switch-overs reliable. For the rest of us, there are now so-called email backup services that make the whole process easier and come in at a few tens of pounds per year. This is a minuscule insurance cost for the peace of mind accorded by the ability to get at important mail even in a crisis. Features and benefitsIn the event of an outage at your site,
The whole point of such services is to allow all your emails to be backed up for a few days and if an important email is required you can forward the email on. In an emergency, you can even download the whole lot. Contact us here or use the form below to find out which email backup service is most suitable for you. -IB- |

Improve your web site search ratings
Not on page 1? Does it even matter? Most organisations start piling money and effort into SEO without having thought it through.

Help at hand. |
This question comes up time and time again, so it's worth dispelling some myths about Search Engine Optimisation. Understanding the motivations of search engines providers is key. In prioritising their results, search engines try to emulate human recommendation methods, such as word-of-mouth and reputation, and the corollary to that is that they try prevent people cheating the system!
Litmus test: "If I had to choose just one method of promoting my organisation, would that be via the web?"
This skew was definitely the case just after the dot-com bubble burst, when tiny, unknown e-commerce outfits would suddenly and inexplicably rise to the top of search results in Google. When the adverts presented don't match the search results on that page, search engines lose revenue and that really is the bottom line. Here are the top three goals for success and the reasoning behind them. They apply to Google or any other search engine.
What about submitting our web site to search engines and SEO promoters?There are limitless numbers of promotion sites willing to submit your site to search engines, but what most of them are after is to put your contact email address on a newsletter list, with which they will bombard you later; promoters often form syndicates and the stream of emails can be relentless! Some newsletters have useful tips, but if you opt for this route, use an email address you can ditch fairly quickly. Better still go to each search engine and find out if they have a “Submit site” page, and avoid promoters altogether. Are there any short-cuts to optimisation?There are some useful tools, such as those which allow you to see your web site pages as viewed by a search engine. These assist you with the fine-tuning part, but don't guarantee a sudden rise in the search results charts. There are other tools which tell you which keywords are more sought after than others (eg climate change), but unless you go down the route of creating a campaign or project that actually fits those words, you are veering towards the tactics of the cheats and search results will suffer. The 'wrong' pages show up in searches!You want your flagship pages (eg About Us) to come up first in search results, but are disappointed when the most popular are events, actions or even courses on a different web site. Slowly a valuable lesson is being learned: what interests your current visitors. You have to draw a balance between attracting larger numbers of viewers arriving for the wrong reasons - with the potential for new publicity - versus smaller numbers who really want to find out about what you do. The alternative - "Don't bother"So is Search Engine Optimisation worth all the hassle? Not as daft a question as it sounds. To understand the motive behind this web litmus test, ask yourself another question: "If I had to choose just one method of promoting my organisation, would that be via the web?". If you find all your supporters and funders through say, networking and events, your web site may just be a bit of puff to furnish background info for those who already know you. Many people operate globally-visible 'closed shop' web sites with no pretensions of promoting themselves; it's just convenient. However if, say, as little as 30% of your supporters sign up via a web form on your site, then it's clearly crucial to make your web presence easy for others to find. Hopefully this got you thinking about your audience, how they come to learn about you, and even whether such things are important. So we've come right away from digital tips and moved into marketing strategy. And if you want to learn about that, why not look it up on the web. Learn ore about search engines. -IB- |

Just when you thought it was safe to go in the comms room
| |
|
Help at hand. |
Got a central comms or server room that looks like this? Chances are it will soon tidy itself. Uh, really? Yep, but only by means of a crisis first! Patch panels often only turn into this kind of spaghetti when too many cooks are involved. Sooner or later someone pulls out the wrong Ethernet plug and plunges a whole department into Internet darkness. Worse still, the weight of cabling starts to drag cables inexorably out of their connector housings leading to a series of intermittent failures that are impossible to trace. Long before you get to this situation, do contact us to help sort it out and save you stress and pointless troubleshooting. -IB- Acknowledgements: Wayne Toolan |

Compare Dell PC energy costs
The purchase price isn't the whole story.
| |
|
Help at hand. |
Ever thought to query how much your new PC purchases are going to cost to run before you buy them? Well now you can run like-for-like comparisons with Dell's Energy saving calculator and the good news is that newer models cost less to run even though they often have better features. Comparing up to 3 systems, we can thus find out that a Optiplex GX270 desktop costs approximately £57.75 (262.56 kWh) a year to run. Stack this against the newer Optiplex 760 with efficient power supply – only £31.12 (141.44 kWh). Laptops too are becoming more efficient. Take the not-so-old Latitude D620 with a 14.1" screen - its 83.3 kWh will cost £18.32 pa. Now a similarly specified Latitude E5500 with the same power supply and default power management, takes those figures down to 65.67 kWh and £14.44 pa, even with its larger 15.4" wide screen. A handy site, though you need to know your Dell model numbers or have the Dell product pages open in a separate window.

Q&A: How to get rid of tracked changes in a Word document?
Question
Hi Mark, | ||
|
Help at hand. |
Word's feature called Track Changes is the likely reason. It's a useful feature that allows people who are sending a document back and forth to collaborate on the final content and see changes the others make via 'red-inking' and pointers. Although forwarding this as a template to someone might preserve headings and font sizes, it also includes all the details of the interaction that occurred during the collaborative process, which get in the way for anyone starting a new document. There is a further impact as you make changes in that Word spawns new temporary versions of the document. So if you started with a picture-laden document of 2MB, you can easily find that 10MB of disc space has been consumed in a short time - no benefit to people working on a small capacity USB memory stick, for instance. The Track Changes feature will appear automatically in such a document and can be turned on and off by pulling down Tools menu | Track Changes, (or pressing Ctrl+Shift+E keys together), or clicking the toolbar icon. But that doesn't remove the changes. What about changing the option on the Reviewing toolbar from "Final Showing Markup" to "Original"? The margin notes and changes stop being displayed, but they're still there, and so is the massive file size. First we need to check that all the types of changes really are going to be removed. On the Reviewing toolbar, click Show, and tick each of the following items:
To finish, we need to move along the Reviewing toolbar a little and click the down arrow next to the red X button marked Reject Change/Delete Comment and choose Reject All Changes in Document.

Clicks of the Trade - Create a manageable tasklist in Outlook
--- Quick tips for happier clicks! ---
| ||
|
Help at hand. |
Task and to-do lists are great helpers. Until they fill up with so many tasks you suffer from overload! Filter down your Outlook task list so that it shows a rolling 'here and now' and make it manageable again. Let's create a new view to show 7 days either side of today's date.
The idea here is to push aside tasks that are a long way ahead in order to focus more on what's happening now. You could equally narrow the filter conditions to show yesterday/tomorrow or last month/next month. Don't forget you can use the Field Chooser to further shape columns in your new view. ** try it now **-IB-
