EMC appliance discovers virtual resources

Wednesday 21 May 2008 @ 7:05 am

EMC announced upgrades to its application mapping technology Tuesday that the vendor says will help datacenter managers discover, monitor, and manage physical and virtual resources with one tool.

The vendor at its EMC World conference in Las Vegas introduced Application Discovery Manager (ADM) 6.0, which features support for VMware (an EMC company) VirtualCenter environments. The support, EMC representatives say, will enable datacenter managers to discover virtual resources and monitor them alongside physical servers in their environments.

"Customers are in the phase of aligning virtualization resources within the physical environment, but also discovering the virtual machines' relationships amongst each other," says Bob Quillin, EMC's senior director of product marketing for the resource management software group. "ADM 6.0 understands the relationships between the physical machines and the virtual environment and helps customers make more informed decisions when adding VMs, which ultimately support critical business applications and services."

Built on technology EMC acquired with nLayers, ADM 6.0 gives users an inventory of applications and maps how they are linked to IT resources, such as servers, network devices and storage arrays. A built-in dependency catalog lets enterprises keep track of software and hardware configuration changes and compare them on a server-to-server basis.

By combining information about the application infrastructure that ADM collects with EMC Smarts' (also an acquired technology) root-cause analysis capabilities, IT can more easily pinpoint the impact of system events and changes, EMC says. (Compare  network configuration management products.)  

ADM 6.0 can map pre-deployment application dependencies to help IT plan for resource allocation in virtual environments. It can also help with managing migrations from physical to virtual by analyzing how VMware impacts existing applications, and it will map the dependencies of VMs and their application components running on a single server, EMC says. The product will also keep configurations consistent across both physical and virtual environments, as well as identify rogue ESX Servers not under management of VirtualCenter.

"ADM 6.0 has the unique capability to look at the virtual switch inside ESX servers and watch traffic, which helps customers understand how VMs are participating in relation to the overall application," Quillin says. "It brings visibility to the virtual environment."

Also new to the ADM product is support for EMC's IT Compliance Analyzer — Application Edition 1.1, also announced at EMC World Tuesday. Combining the two capabilities enables datacenter managers to ensure their VMware environments remain compliant with regulatory requirements such as PCI DSS and HIPAA, EMC says.

Citrix makes the desktop virtual with XenDesktop

Wednesday 21 May 2008 @ 7:05 am

Hoping to stay a step ahead of rival VMware, Citrix Systems is now shipping its XenDesktop product line of desktop virtualization software.

Announced Tuesday at the company's annual Citrix Synergy conference in Houston, XenDesktop comes in five editions, including a free bare-bones Express Edition that will give small businesses and developers a chance to test the product for as many as 10 users without having to worry about licensing fees.

XenDesktop delivers the Windows desktop to clients over the network, using virtual machine technology. These virtualized desktops are actually run on a central server, making it easier for them to be managed by IT staff.

After having a virtual monopoly on remote Windows desktop connection software, Citrix has been feeling some competitive heat lately from VMware. Analysts say VMware's Virtual Desktop Infrastructure is still a year or two away from providing stiff competition to Citrix, but the virtualization software vendor, which is majority-owned by EMC, clearly has Citrix's attention.

In October of last year, Citrix spent $500 million to acquire VMware competitor XenSource. XenDesktop uses Xen's hypervisor software, and Citrix has a datacenter product called XenServer that is based on XenSource's product.

Although XenDesktop takes a different approach from Citrix's older XenApp software (formerly known as Presentation Manager), it is a similar type of product. With XenApp, users are delivered applications, or even very basic Windows environments called published desktops, from a central server.

Published desktops are generic and cannot be easily customized for individual users. In contrast, XenDesktop gives the users a full-featured Windows environment, but one that can still be centrally managed by IT staff.

This will make XenDesktop appealing to many more desktop users in the enterprise, said David Roussain, Citrix's corporate vice president of virtualization marketing.

"We see that the desktop virtualization market is going to grow dramatically over the next five years," he said. "Enterprises need to find a way to dramatically lower the cost of delivering desktops in the corporation."

That need to centrally control desktops may appeal to very large companies that are worried about things like desktop policy compliance, but smaller businesses will stick with Citrix's traditional products, which are widely used to give workers remote access to applications, said Roman Gruzdev, CEO of IT consultancy Sequentur, in Arlington, Virginia. "I mostly do small and medium businesses, and for them, I don't see how it's going to be an advantage to have XenDesktop."

Because it delivers a customized version of Windows, where things such as Windows DLLs (Dynamic Link Libraries) can be changed, XenDesktop will make it easier for some applications to run with XenApp. However, because the software is being run remotely, there will still be limitations. Graphics programs that use a lot of processor power may not work well in XenDesktop environments, for example.

And companies that are provisioning hundreds of presentation desktops on a single XenApp server will have to add hardware to serve up that many versions of Windows using XenDesktop. Roussain says a Citrix server that could provide 200 to 300 presentation desktops can handle maybe 30 virtual machine desktops with XenDesktop.

The brewing fight between VMware and Citrix in the desktop virtualization market will ultimately be a good thing for customers, said Brian Madden, an independent industry analyst who publishes a popular desktop virtualization blog. "For the past 10 years, Citrix was an absolute monopoly. There was no one else at the enterprise level doing what Citrix was doing," he said. We're going to go, for the first time, to market-driven pricing versus monopoly-driven pricing."

In fact, some customers may already see signs of this in Tuesday's announcement. Enterprise and Platinum XenDesktop customers get a free license to use XenApp with their virtual desktops. Normally, XenApp costs $450 per concurrent Enterprise user and $600 per Platinum license. That's more than the $295 and $396 that Enterprise and Platinum XenDesktop users pay.

Available immediately, XenDesktop also comes in Standard and Advanced editions, which cost $75 and $195 per concurrent user.

Free Wi-Fi for AT&T Laptop Mobile Broadband Subscribers

Wednesday 21 May 2008 @ 7:05 am

AT&T extends its free Basic Wi-Fi package to laptop-based mobile broadband subscribers, but not to smartphone users, including iPhones: This is a logical move, vastly overdue, because it’s a better experience for a laptop user to have access in a Wi-Fi hotspot, while simultaneously removing load from AT&T’s 3G network. This was predicted many years ago–as early as 2001 by EarthLink, Boingo Wireless, and Helio founder Sky Dayton–that 3G spectrum was scarce enough and expensive enough to operate that using Wi-Fi like a local heat sink to bleed usage off would keep 3G usable.

The other advantage, of course, is that 3G laptop users that find themselves out of the HSPA coverage area offered by AT&T don’t fall back to EDGE or GPRS as long as they can find an AT&T-included hotspots. No hotspot operator likes to guarantee a particular local network speed, but I know that Wayport–which has or will build nearly all of the 17,000 locations in question here–aims for T-1 speed (1.5 Mbps each way) and quality (guaranteed uptime), depending on availability.

Windows laptop users with AT&T’s Communication Manager software (version 6.8) installed will be automatically logged onto hotspots–and, I would guess, logged off 3G whether the user wants that or not! I’ll be curious about reports from the field.

A 5G/month ($60/month or greater) plan is requierd for free Wi-Fi service.

The Boy Genius Report quotes what appears to be an internal AT&T memo about today’s launch that free Wi-Fi for smartphones is coming later in 2008. Boy Genius has a remarkably good track record for a rumor/leak site, so I’m inclined to believe their report.

Three Essays on Muni-Fi You Should Read

Wednesday 21 May 2008 @ 7:05 am

In the aftermath of the last man standing, MetroFi, announcing its metro-scale Wi-Fi endgame, three useful essays have appeared: If you’re trying to understand the past, present, and future of the space, I recommend you read these short opinion pieces.

First, Karl Edwards of Excelsio, a firm that consults on municipal broadband, lays out a pretty straight case as to why EarthLink, Kite, and MetroFi’s networks, among other one-offs, were designed to fail. I’ve written about aspects of this over the last four years, but Edwards is succinct. In part, EarthLink offering to build Philadelphia’s network at no cost to the city set the mold wrong for all networks to follow. We’re resetting now, and Wi-Fi’s moment may have passed.

Edwards offers as one the constraints set by cities, “Expectation that the network would cover 90-95% of the City with wireless coverage as opposed to just in the areas where there was a solid business case.” This has been a problem I’ve had for a couple of years when it started to become clear that 90-plus percent coverage wasn’t in the interest of the ISP–nor in the city’s interest because these networks couldn’t be completed.

Edwards also notes that when consulting for Grand Rapids, Mich., which chose Clearwire as its wireless partner, EarthLink told the city that they expected a conservative 22-percent uptake for their Wi-Fi service by end of the fourth year. Given that in mature markets, a high-single-digit uptake is considered very good, that’s shows how the Excel spreadsheets were skewed. USI Wireless’s estimates for break-even require less than 10 percent of the population in their covered areas to subscribe, and their numbers of subscribers to date are tracking that number closely.

He closes with a set of eight principles for wireless network builders to come to the table with and cities to adopt, all of which I agree with.

Next, Esme Vos suggests a very modest proposal: San Francisco should have required all its cafes to offer free Wi-Fi, and then Fon or others could have aggregated and bundled access to these locations. There’s a long set of comments accusing Esme of communism, socialism, utopianism, and other isms. The post and the comments make for lively reading.

Finally, Craig Plunkett, who operates hotspot networks around New York City and Long Island, chimes in with a summary of these opinions and the notion that muni-Fi jumped the shark when Ocean City, N.J., decided to put Wi-Fi in garbage cans. He points out that “an infill strategy” of providing service where needed and then extending from there is effective.

The Best Way to Cook Your Vegetables [Cooking]

Wednesday 21 May 2008 @ 6:05 am

fruit-and-veggies.pngIf you’ve been following author Michael Pollan’s simple eating philosophy—“Eat food. Not too much. Mostly plants.”—you’re trying more than ever to incorporate vegetables in your diet. What you may not know, however, is how to best prepare those vegetables so you’re getting the most nutritional value. From the New York Times:

“There is a misperception that raw foods are always going to be better,” says Steven K. Clinton, a nutrition researcher and professor of internal medicine in the medical oncology division at Ohio State University. “For fruits and vegetables, a lot of times a little bit of cooking and a little bit of processing actually can be helpful.”

Though the article emphasizes that no cooking method is best, it does explain the trade-offs you make when you make the decision to cook or not to cook.

For example, boiling carrots increases carotenoid levels while decreasing polyphenol. Often you can cook better with your microwave than your stove, and—according to the article—microwaving can retain more vitamin C than other methods. You don’t have to weigh the health options every time you decide to prepare a vegetable—you’re eating vegetables, after all, which is already healthy—but do know that variety in your preparation methods is advantageous. Let’s hear how you prefer to prepare your veggies in the comments.

Five Extensions You Won’t Need with Firefox 3 [Firefox 3]

Wednesday 21 May 2008 @ 6:05 am

Now that Mozilla’s locked down Firefox 3’s feature set, it’s clear the new browser iteration will render some extensions obsolete. Firefox 3 will include functionality out-of-the-box that you could only get with add-ons before. Let’s take a look at five extensions you might not need when you switch to Firefox 3.

  • NoSquint: Never have to enlarge the text on that web page with the teeny tiny font size again. Firefox 3’s new “Text Only” zoom feature doesn’t enlarge images, and is smart enough to remember your text size setting on a per-site basis when you visit again.
  • Google Gears: While offline web application support is still a ways off, Firefox 3 does have support built-in and ready for webapp authors to turn it on, effectively making Google Gears unnecessary. It will be very interesting to see Gears’ fate in the face of Firefox 3 offline webapp support, and which webapps support which. Overall, it’s great news for users who want their data whether they’re online or not.
  • Resize Search Box: Sometimes, it’s the little things that make us happy, like a search box that can be as big or as small as you want without having to hand-edit CSS. In Firefox 3, just grab the dot to the left of the Google search box and drag and drop to the size you desire. It doesn’t auto-expand as you type, however, like Searchbar Autosizer does; perhaps in Firefox 4.
  • DownThemAll: Ok, so Firefox 3’s improved download manager definitely does not have ALL the features DownThemAll offers, but it does include dTa’s key feature, which is the ability to resume downloads even after you’ve restarted your browser or lost your network connection. We still do love dTa for all the other download acrobatics it can do; see more on how to supercharge your Firefox downloads with DownThemAll.
  • Better Gmail and other Mailto: handler add-ons: Pre-Firefox 3, to invoke your web-based email compose screen from a web page link, you’d need an extension like Better Gmail, toolbar, or a third-party program like the Gmail Notifier. No more: Now Firefox 3 can register web-based protocol handlers, meaning it can open certain kinds of links (like iCal calendars and email addresses) in webapps of your choice (like Gmail or 30 Boxes.) (Note from Mozilla: web applications will have to first enable this by registering as handlers with Firefox).

What extensions have you NOT had to install with Firefox 3? Tell us in the comments.
