vSphere 4.1

Just a year after introducing vSphere 4.0, which ushered in dramatic performance gains and increases in configuration maximums, vSphere 4.1 is now available. Once again, the performance gains and increased configuration maximums are big. These are the kind of gains rarely seen in a major release, let alone a minor rev update.

Another notable piece of information about vSphere 4.1…it will be the last release to feature the ESX product. ESXi has long been hailed as the successor to the vSphere throne, and now they have set a date. Well, not a date, but a marker. The next release of vSphere, likely in 2011, will only include the ESXi product. For all of those vendors still relying on the CLI of ESX, wake up and smell the vMA coffee.

A few highlights in the many vSphere 4.1 improvements are:

  • 3x increase in VMs per host
  • 2x to 4x increase in concurrent vMotions (no longer VMotion as of 4.1)
  • Improvements in the scalability of Linked Mode (I LOVE this feature in vSphere)
  • Added Memory Compression to provide further gains in efficient memory utilization
  • DRS VM Host affinity rules (more on this below)
  • Active Directory integration on the ESX/ESXi Host
  • Multiple vCPU per virtual socket (think of vCPUs as cores in a virtual multi-core proc)
  • Host Profiles can now roll out password changes (host profiles are right up there with Linked Mode for me, great new feature in vSphere)
  • Fault Tolerance (FT) was made a little more forgiving in handling patch level mismatches
  • Network I/O control to group and manage NIC bandwidth by traffic types (VM, vMotion, FT, etc)
  • Load-Based Teaming for vNetwork Distributed Switches, to keep the load balanced across all physical adapters (vDS is probably my favorite new vSphere feature)
  • Hardware Acceleration with vStorage APIs for Array Integration (VAAI – more on this below).
  • ESXi can be deployed via a new scripted install feature (as a long time Unix/Linux admin, I really like this…but I did not have the time to test it in the beta)

DRS VM host affinity rules are something I was very excited to see in the beta. As I have been implementing vSphere and designing a private cloud environment, a lot of effort has gone into the right methods for determining cluster groupings. Licensing is always a pain point in these discussions. I lose efficiency in creating a two small licensing-driven clusters for applications A and B, while maintaining N+1 within both clusters. If I could create one larger cluster, forcing the appropriate VMs to remain on their licensed group of hosts, I gain efficiency in the N+1 capacity if nothing else. There is also ease of management and a number of other advantages to this.

Now, throw into the mix that application A never allows the instances to run on unlicensed hardware, but application B will allow the instances to temporarily run on unlicensed servers in the event of a hardware failure. The new affinity rules will allow you to state that group A can never run anywhere else, while stating that group B can run somewhere else in an HA event. Now this feature becomes even more valuable.

Another new feature worth dedicating a few lines to is the VAAI. This will allow vSphere 4.1 to offload specific storage operations to compliant storage hardware. Why make vSphere use the less efficient “this copy command will work anywhere” approach for Storage vMotion when NetApp or EMC already have specialized commands on their arrays for these functions and know the most efficient way to carry out the task. This is a true win-win partnership with the storage vendors and one that can yield significant performance gains in your environment. Look for the major storage vendors to all be announcing their support for this within days, not weeks.

Finally, I will part with a list of KB articles passed on to me from our friendly neighborhood Technical Account Manager at VMware. Carl Olafson has always been quick to share information with me at my work, and this particular list is all public info. That being the case, I will pass it on to you:

Shiney new IT toys

All that glitters is not gold…sometimes it is simply a distraction. Sometimes, and I have been guilty of this, we let the desire to implement technology get in the way of meeting business needs. It can be very tempting, after evaluating an amazing new technology, to then begin looking for excuses opportunities to use it. Sometimes you find that true win-win scenario where that technology is the exact fit, and sometime you end up making it fit in the hopes that it will show increased value in the future.

Fred Nix hit this point very well with his post on 1/4 inch drill bits. Sometimes we simply need to step back and evaluate why we are looking at a new technology. If you are impressed with a presentation or excited after evaluating a new technology, then make note of that and add it to your toolbox of solutions. Then, when the right opportunity presents itself, reach into your toolbox and pull out the right solution for the problem in front of you.

Read more about this in my article “New IT Trends: Are they right for you?“, then come back here to leave any comments. As always, your thoughts and feedback are encouraged.

Opportunity Cost

When you are presented with two or more mutually exclusive options, you are going to have to pass up an opportunity. The key to making the right decision not only lies in knowing the value of both options, but in looking for a possible third option and assessing the value of that option as well. The value of the opportunities not taken are the “opportunity cost” of your decision.

A simple way to explain opportunity cost is to consider selling an item at cost. If I buy a widget for $10, and I sell it to you for $10, I have recovered my cost and lost no money…right? That is true in simple financial terms. However, consider that I could have easily sold the widget for $15, that decision had an opportunity cost of $5. I passed up an opportunity to make $5 by selling it to you at cost.

That concept changed the way I approach IT decisions, teaching me to always consider the business value and cost. No matter how good my design, the business may have other opportunities available that would yield a better return. My designs not only have to be good, they have to be valuable.

Another impact of learning this lesson…I no longer ask my friends who own businesses to sell me items at cost 😉

vExpert 2010

First, I am humbled and honored to have been a vExpert in 2009. As the year went on, and I got to know more of my fellow vExperts, I was in awe of the people that I was sharing this title with. In fact, it inspired me to work even harder and to put more effort into be an active member of the virtualization community.

That being said, I am amazed to once again receive the vExpert award for 2010. I look forward to learning from my fellow vExperts, as they are a truly talented group of people. I have yet to meet a vExpert that was not both highly talented and eager to assist. In fact, that is why they are vExperts.

Some of you may be asking, what is a vExpert? VMware describes it like this:

The VMware vExpert Award is given to individuals who have significantly contributed to the community of VMware users over the past year.

The criteria for vExpert selection are value to the community, technical merit, effectiveness, professionalism, reach and effort. The group is full of authors, bloggers, technology leaders and a wide range of highly skilled individuals. Again, I am humbled to have been grouped with these people.

Being a vExpert led me to become more involved in sharing my opinions and contributing to discussions via twitter. I also launched this blog site and began writing for Tech Target. In these pursuits I received a lot of input and advice from fellow vExperts like Steve KaplanDavid Davis and Scott Lowe. Those names stand out, but so many others have contributed to helping me grow. John Troyer, the driving force within VMware that launched the vExperts and a number of other programs, worked very hard to add value to this program last year. John is promising even more from the coming year and I cannot wait to see what that will look like.

To all of my fellow 2009 vExperts, thank you so much for your encouragement and assistance, it was an honor to share that title with you. To my fellow 2010 vExperts, congratulations! I am honored to be in your company and I look forward to getting to know you better as the year goes on.

Is virtualization cloud computing?

There is a lot of talk about virtualization and cloud computing, and too much effort is spent to link the two. With so many virtualization vendors releasing a flurry of cloud-related technologies, and forming cloud-centric partnerships, the emphasis is understandable. However, it can really muddy the waters and has a tendency to lead people to think the two terms are synonymous. In truth, though complimentary, the two technologies can exist independently. In fact, cloud computing is as much methodology as it is technology.

For more on this topic, please read my article on SearchServerVirtualization at http://searchservervirtualization.techtarget.com/news/column/0,294698,sid94_gci1513869,00.html

Once you read the article, feel free to come back here and leave a comment. This is  conversation that can go in so many directions, but I think it is an important one to have.

Java abstraction and virtualization

The last few weeks have been very active with a steady stream of press releases related to java in virtualization and java in cloud computing:

It is interesting to see the technology circle of life return to java, as java did so much to first introduce abstraction into mainstream technology.  By abstracting the application from the OS, java made great stride in turning our attention towards the application and away from the OS. Hypervisors then turned out attention away from the hardware, and now the two are being used in conjunction to truly enable us to focus on what matters…providing services.

VMWorld 2010 – Please Vote

Public voting for VMWorld 2010 will be live through May 26, so please make sure you stop by, review the submissions and vote for the ones that you would like to see. This year, VMware received a record number of submissions, and will be using a model of fewer high quality sessions with more repeat opportunities to attend. With more people competing for fewer slots, your opinion is even more important. To vote, go to:

http://www.vmworld.com/community/conferences/2010/cfpvote/

As a shameless plug, here is a rundown of the sessions that I am involved in. I have presented at the last 3 VMWorld conferences, and am very passionate about the topics I have submitted this year (due to a flaw that only shows one presenter per session, my name will not appear as presenter on some of these tracks on the voting site).

Tech & Architecture – PC8279 From Guessing to Knowing: An Effective Architecture
http://www.vmworld.com/community/conferences/2010/cfpvote/hapcloud

This is a great session that I have worked on with Michael Mannarino from VMware’s Professional Services Organization. We will walk you through a sound approach to designing an environment where decisions are based on defensible data and where every business requirement is mapped to a design element. As organizations prepare to expand virtualization further into their environment, or even to develop cloud computing strategies, they not only need to be able to solidify their requirements and practices, but they must know how to measure and enforce compliance. By breaking available resources (memory, cpu, storage, etc) into units of allocation, this approach assists organizations in better understanding how business requirements impact the ratio of raw capacity to usable capacity.

Tech & Architecture – TA8351 Linux P2V Hurdles and How To Overcome Them
http://www.vmworld.com/community/conferences/2010/cfpvote/tarchitecture

This session breaks down the tools available for Linux P2V migrations, and the caveats to each one. In the Linux world, there are a number of “gotchas” in the P2V process, and many failures are actually near misses that can be quickly repaired in a few easy steps. I have 14 years of Unix/Linux experience and over 4 years of experience with Linux on VMware.

Death of the OS

I wouldn’t begin the funeral procession just yet, but the server OS may have to come to grips with its own mortality soon. As virtual appliances progress, they are returning the focus to the application and moving the OS from the role of a maintenance burden to one of a service enabler.

Case in point, I used to run a 486 workstation my home router. It ran Linux and had two NICs, with the ipchains and ipfwd services providing my firewall and routing. I loved building that, I even had the entire thing running DSL Linux and booting form a write-protected floppy at one point. Over time, that server’s value diminished. For $30, I could by a wireless router that did much more, and did not require hours of messing with NE1000 NIC drivers every time I did a kernel upgrade. The home router appliance removed the administrative concerns of the OS, actually locking it away from my meddling fingers. I no longer know or care what distribution of Linux it uses, what rev of drivers are in use, or even what the hardware components are. I turn it on, answer a few questions from my web browser and walk away. Aside from the occasional firmware updates, I forget it is even there…and that is of tremendous value to me.

When your server OS requires more maintenance than the application or service being delivered, your priorities are out of alignment with your business needs. Virtual appliances are seeking to return a healthy balance to the data center, turning the attention back toward the service. To read more of my thoughts on this, read my latest TechTarget article, “JeOS: Death of the operating system“.

As always, your feedback is welcome.

VMWorld 2010 Content Selection process

The process of selecting sessions for VMWorld 2010 is rolling along, and registrations is now open for both the US and European conferences. With virtualization and cloud computing being the hot technologies on every business’ radar for 2010, it is no surprise that this year brought in a record number of submissions for the VMWorld 2010 Call for Papers.

Changes

For anyone familiar with the content selection process for previous VMWorld conferences, there are three changes to be aware of this year. First, there will be no registering for sessions. The process of registering for sessions has always ended in popular sessions being overbooked, with people waiting in lines with the hopes of snagging some space to stand in the back of the room or simply being turned away.

This brings us to the second change, fewer unique sessions. With a record number of submissions and no registration for sessions, why lower the number of unique sessions? Good question. The goal is to have higher quality sessions, and more repeats to insure everyone gets a chance to attend them. Hopefully, this will lead to fewer lines and more opportunities to catch the sessions that matter the most. If you are like me, you have been in the situation where some time slots on the session agenda had nothing of interest for you, while other time slots had multiple items and you could only pick one. With the new approach, I hope that I will not be faced with those difficult choices this year.

The final change is one I think everyone will like. In each track, a percentage of sessions have been allocated for selection through online voting. Track Owners will be soliciting feedback from the Content Committee and selecting their portion of sessions, then the remaining submissions will be opened up to the public for online review and voting. I think this is a great idea, giving people a chance to provide input on what they want to attend at VMWorld.

Process

Here is a quick breakdown on the process for selecting this year’s content.

<IMAGE MISSING>

CORRECTION: final emails will now go out week of June7, not June 2 as originally stated.

April 9 – Call for Papers Ends
Originally set for April 2, the Call for Papers was extended to April 9. This process is for the non-paid sessions at VMWorld. Vendors and partners can purchase sponsorship packages that come with paid sessions for promoting their services, but this process is for the non-paid sessions, so all content is supposed to be focused on business and technical value instead of selling products or services. To allow the Track Owners more control over their tracks, filtering of marketing content and incomplete submissions are only lightly applied at this point.

April 19-30 – Content Committee Voting
The Content Committee is selected from a cross-section of customers, partners and VMware employees. This committee will review, rank and leave comments for a particular track(s) of content. Each submission is ranked on a scale of 1-5. If necessary, they can also work with the Track Owner to request additional information from a submission owner to better understand their content and the message they hope to convey.

May 3-7 – Initial Session Selections
At this stage, the Track Owners will use the feedback from the Content Committee to aid in selecting a predefined portion of their total conference sessions. After Track Owners make their initial selections, another round of filtering will take place. Submissions that are too heavily geared towards marketing, that are incomplete or that fail to line up with the conference tracks are eliminated. This leaves a selection of good content for the public voting.

May 14-26 – Public Voting on vmworld.com
Remaining sessions will be made available for public voting on the vmworld.com website. If you do not already have an account here, you can set one up for free. You will be able to review session content and vote on what you think would be the most valuable material for VMWorld.

May 31-June 4 – Final Session Selections
The public votes will be tabulated and used to fill the remaining track sessions for VMWorld 2010.

Week of June 7 – Notifications Sent to Submitters
Good or bad, this is when submitters will learn their fate. You cannot cheat and assume that if you content was not available during the public voting that it was selected in Initial Session Selections (I already checked on that), because of the two filtering steps that take place prior to the public voting. The week of June 7 will truly be your first chance to find out the fate of your submission.

Let The Games Begin

I personally reviewed 275 submissions in the “Private Cloud – Management” track. I found very few that were not good, and many that were great. I do not envy the Track Owners that have to narrow this list down, but I do look forward to a second chance to vote during the public voting. I am excited about the changes, and I cannot wait to see the final session list. I think these changes will make for a better experience, I just hope my submissions can make it through this more difficult selection process.

NOTE: I updated this post to reflect that final notices will be sent to submitters the week of June 7, not on June 2 as originally stated. Public voting also moved to start on May 14.

iPad – The Business Use Review

In my initial post reviewing the iPad, I mentioned my struggle with deciding if I would use it for home or work. This was a surprise, because I did envision it being anything but a home media device. In the first 48 hours, I was surprised to see my thoughts on this changing. However, that introduced a new problem; to allow my family to use the iPad, I really needed to not have it syncing with my business Exchange account. I do not want to risk unwanted messages being accidentally sent from that account or, even worse, data being deleted. After 3 weeks of using the iPad, this post will cover what I have learned and how I plan to use it for work.

First, I never undock my laptop to carry it around for meetings anymore. It stays at my desk and my iPad goes to meetings. It has hundreds of pages of project documents stored on it, and can access SharePoint to gather more if needed. Add in a bluetooth keyboard and this is a great portable platform.

<IMAGE MISSING>

When I am away from the office, I will either use just my iPad and iPhone to connect to WebEx meetings, or I will use the iPad to reference materials while I use my laptop for the WebEx or Live Meeting session (I wish Live Meeting worked with iPad).

<IMAGE MISSING>

My iPad is viewing project docs, iPhone is on a conference call and laptop is connected to a Live Meeting session. The frozen lunch, that was a mistake 😉

In general, the iPad has not replaced my laptop. I am a “power user”, and simply have too many utilities to abandon a laptop at this point. However, it has replaced a large portion of what I used to rely on my laptop for, and it actually does a better job at most of those tasks. In truly fit the bill of being better than a laptop at some things, and better than an iPhone at some things. Convenience, UI, battery life and simple geek points aside, it is largely the apps that have moved this from a home media device to a work device, so let’s look at the apps I am using:

Let’s start with the native apps; Notes, Mail, Contacts and Calendar. You can find a lot of reviews on these apps, so I will be brief. The layout and usability of each of these apps is a huge improvement over the iPhone version. Notes was very easy to use, and I found myself using it to store all kinds of thoughts. The biggest drawback…no folders. To use it extensively, I would need to be able to better organize my notes into folders. Calendar is probably my favorite’ with it’s landscape format providing a complete view of my daily and weekly schedule. I found myself often leaving this open in landscape mode at my desk. As nice as the contacts/calendar/mail apps are, I am very used to these apps on my phone and will likely end up disabling them to make my iPad more family friendly. At the most, I may leave the calendar sync in place. However, if you use multiple email accounts on either the iPad or iPhone, I recommend iSignature to manage multiple email signatures.

Next, I will look at the apps that Apple should have included (and I imagine they will put back in future releases). I installed Pcalc Lite to make up for the missing calculator. I also installed Voice Memos to replace the missing voice recorder. These are not critical apps, but still very useful. I am hoping that the native versions of these apps were left off to allow time for Apple to retool them in a manner similar to the email and calendar apps. I would have preferred a simple native version up front, with improvements alter, but the makers of Pcalc Lite and Voice Memos picked up the ball (thank you).

As for Apple’s paid apps, iWorks was well worth the money. For those unfamiliar with iWorks, Pages is a word processor, Numbers is a spreadsheet app and Keynote is a presentation app. I can use Safari to connect to our corporate SharePoint server and open documents, then I get the “Open in…” dialogue in the upper right corner that will allow me to open word/excel/powerpoint documents for editing on my iPad. This same dialogue also exists for email and calendar attachments. This is a very nice interface, and I think the Numbers interface is very nice. In just a few minutes, I was able to use it to create a spreadsheet that took VMware cluster stats and calculated capacity based on an equation (may be a session at VMworld, but that’s another story). Though I have only used Keynote to view a few PowerPoint files, I have really enjoyed using Pages and Numbers. The iWorks suite was an immediate purchase for me, and may be what initially made me begin to see the iPad as much more than just a media device.

For me, the next apps that I added were the WordPress and Analytics Lite applications that I had used on the iPhone to manage my blog and check my Goggle stats. Analytics Lite is still an upscaled iPhone app, but the WordPress app was rewritten for the iPad. I wrote my initial iPad review on this app, and am writing this on it right now. I maintain multiple blogs, and this app allows me to easily manage my pages, posts and comments on all of these sites.

Another useful app that got a nice redesign was the YouTube application. Anyone at fails to see this as a business tool needs to seriously reconsider their definition of a business application. Companies like VMware have their own channels on YouTube, and provide a lot of educational videos to give in depth information on their products and services and to give insights into their technology direction. I have found this to be extremely valuable.

On the topic of social media, I have also found TweetDeck to be an extremely valuable app. This may also challenge your definition of a business tool, but I only use twitter for professional communications. The information I have learned from the people that I follow on Twitter has been invaluable at work. I have also been able to reach out for advice and get a range of quick responses to provide me with good input as I look to narrow down targets for further research. I would say this app is up and running on my iPad at work even more than the calendar app.

The next category is totally job specific, a set or tools I use in IT. This includes VNC Lite for connecting to my iMac and RDP Lite for connecting to workstations and servers. I also use Touch Term for establishing ssh sessions to my iMac or to other unix/Linux devices. And for personal connections (family and friends tech support calls), I use the LogMeIn app. As you can tell by the many “Lite” apps that I have already mentioned, I am adverse to paying much for apps. However, I did cough up the $29 for the LogMeIn app on the iPhone. This app had saved me several house calls, and I was very pleased to see it updated for the iPad. Not only was the iPad version free (an extension of the iPhone app I already owned, and not an entirely new app), but it also had some significant improvements to take advantage of the iPad improved screen size.

This is RDP Lite. Not as nice as LogMeIn, but free and better for direct connections.

Quick ssh session with Touch Term.

Two other IT tools that I find useful for quick data lookups are DNS Lookups and Net Utility. Where the purpose of the DNS Lookups app should be pert obvious, the Net Utility allows me to perform network pings, port scans and whois lookups. Both of these are iPhone apps that upscale for the iPad, but these apps are not really visual anyway.

I have also found the improvements to the WebEx application to be very useful. This has allowed to multi-task and watch several presentations from other meetings (don’t tell my project managers). Even when at my desk, this allows me to put the meeting presentation on my iPad and free my computer screen up for…well, multi-tasking again.

Finally, I have saved my two most valuable apps for last. iSaveweb and GoodReader have not only provided business value, but they have eased my back pain. I removed a pile of papers and files from my backpack that was over 3 inches tall. This was several hundred pages, and is now all on my iPad for easy retrieval. I used iSaveweb to capture all of my web pages for offline reading. These were mostly articles that I wanted to read, though I had been carrying some of them over over a year. All of my documents and PDF files were placed in GoodReader. GoodReader not only organizes everything into folders and interfaces with my DropBox account, but it also indexes everything for searching. Both iSaveweb and GoodReader also provide interfaces for easily exposing their files shares on your network to upload and download files, though GoodReader can also share files in a number of other ways. If it’s web interface was a little nicer, it may replace iSaveweb altogether. Not only is GoodReader free, but it is likely the single most valuable business app for the iPad.

<IMAGE MISSING>

Before GoodReader, I was carrying this three ring binder home every night and to most of my meetings during the day. I also had a stack of several hundred documents and articles in my backpack…all in GoodReader now.

I am still looking for a good app to take and organize notes in. GoodReader can take notes, but I am not blown away by that part of the app.

Overall, I hope is will give you a little information on the many ways that an iPad can provide you with business value. For the price, the many non-business uses, the long battery life and the amazing interface, finding these many business uses for the iPad was a pleasant surprise. In fact, I know several initial iPad purchasers that are seeing this value as well, and it may just drive some of us to buy a second iPad.
