  • -> I began my career running around replacing computers every 4 years at a large district with 1500 computers. Always thought that it was a waste of time and effort. A staff of three moved 300 clients from one school into another, only to be scheduled to be replaced the following year.-> Most often times the processor speed was adequate and the culprit was the Hard drive or amount of RAM- Reimage using RIS. What about individual HALS?-> Maintaining a network of individual machines can be complicated and inconsistent. ->Thought to myself there has to be a better way.
  • Textbook layout.
  • -> Unlike windows, I didn’t feel comfortable administrating something that I could not fix. I promptly went to training where I began contemplating that if I can virtualize servers and remotely see consoles, then why can’t I virtualize client machines.-> Began to consolidate and convert existing systems into Virtual Machines. Systems such as a DNS server. Instantly began to work better. Virtualized FSS food service server, Forefront Antivirus server, Virtual Center (because of limited funds)->Once I felt confident, I began discussions with vendors discussing how many VM’s could fit on one server and licensing that would be needed. What types of thin clients are there and how cheap could I get one. Who makes thin clients?
  • 1. You can use legacy PC’s as a fat client, however that is still inefficient in my thought process.Oddly, this picture represents the district’s move to smaller footprints. Notice that the GX620 does not include a CDROM. The S10’s footprint allows it to create more workspace in any environment. Also added X90L laptop with Windows embedded which you will hear described later.Also added the Wyse R50l Suse Enterprise Thin Client to our inventory so that we could utilize PCOIP. (200 S10 - 300 R50LE PCOIP)
  • Dhcp now sets the ini file path and after 2 restarts the configuration is set.
  • -Clients are configured by a central configuration file that is accessed via FTP on the Thin Client Manager from the actual thin client.USB functionality is added through a simple command at the bottom and is activated through a KEY that is assigned by Wyse.-Command to add the unit to the Management server is assigned through DHCP as well. No lost thin clients.
  • -Wyse Device Manager -> In one console, you can manage every thin client that your district owns. Colors indicate if the thin client is on/off, and by right clicking can remotely view, restart or wake on LAN. Other key information located here is IP address, firmware version and model.
  • In my deployment, I grouped a lot of programs into a pool called 1. BASIC (1 because it will come up first in the list!) This is a thin clone running Windows ThinPC that has a lot of the extras removed. It works very well and utilizes less memory than the full version. We also utilize this for our secretary pool as well. I think we had it down to a 10 second logon.We also have a pool named 2. Advanced that has AutoDesk and visual studio on it for the programming class. But because we have thin clients in every labs, the room no longer matters. Students can now access them from home.We also have full clones for administration that is accessible from any where. Software that doesn’t run on a tablet can be utilized by logging into our cloud simply named (they can monitor building access via security cameras or now work on office documents securely.)
  • During logon storms or slower periods, SAN headquarters will allow you to make an informed decision. It has all the data you need from your SAN to determine what is causing the problem. I love data.So no matter which part of your implementation you are concerned about, you should know that there are centralized management consoles that will aid your troubleshooting.
  • So back to my implementation.-> 35 computers were replaced by thin clients in the libraries as the program requirements were easily met by the new system. Libraries included were high school and middle school and because of different schedules, virtual images are shared and the total images are less than the amount of thin clients.
  • Pretty impressive when you implement a solution and the end user doesn’t realize there is a difference!!!
  • Initially, we started in one elementary building and added 50 thin clients. That was 4 or 5 years ago, but currently all student devices in the elementary schools are thin clients. -> Pre-k – Grade 4 use a variety of online materials and games and the thin client allows enough processing to accomplish their task.-> Additionally, printers reside in the hallways and eliminate the need for local printers. USB drives do continue to work and allow teachers access to projects off site.
  • Previously these buildings had surplus computers that were inadequate for the tasks that were being required. At times is was difficult for teachers to access email.
  • Thin Clients are amazing when it comes to power efficiency. Dell 745 uses about 90 watts idle while a thin client uses about 15 No doubt that it extends the lifecycle. Last year was the first year that we saved budget money due to our new lifecycle. I’ll let you know what that is when I start to see them die.Classrooms of the future was a state grant that gave our district 300+ laptops that would enhance student learning in the classroom. It was thoughtful, However, our district new there was not going to be sufficient funds in the state budge to replace these laptops at the end of their lifecycle. The thin client program would have to facilitate savings to replace those laptops via the district budget.
  • Year 1 and 2 show the savings from the Thin Clients paying off Infrastructure cost such as the Equal Logic SAN. Year 3 shows a total of $82,000 due to an existing budget item of $10000 for replacement servers. Due to server virtualization the servers can be absorbed into the infrastructure. After 3 years, savings accrue to $75000 which will replace one half of the CFF laptops. With all 500 desktops replaced or life extended due to thin client replacement, the full 82,000 can go toward replacing the other half of the CFF grant.Even if a full 500 thin clients are realized, no new money will need to be added to the budget to start replacement of the CFF laptops.
  • -> Certain situations require teachers to have access to a normal workstation. Situations such as DVD players and high quality multimedia. Though these situations are far and few between, you will need to recognize that they do exist.->Pooling of workstations can help utilize images that are not used by anyone or essential share. Our environment is not a 1 to 1. For instance we have 250 machines for 500 thin clients. Does it get close sometimes to filling up, yes but that’s why they make it easy to adjust.
  • Because of pooling, we ran into an issue with printers. We initially added all the printers to the machines via GPO, but that would install the printers everytime a userlogged into a machine created A LOT of extra I/O. Buildings were already subnetted, but we also subnetted labs and set the policy to install based on subnet.We had the student profile removed for security reasons. So everytime a student would logon it would generate a new profile. This year we took time and redirected folders required for the profiles and have seen a great performance savings. This can also be accomplished via view persona management.An overall attitude district wide was maintained that this was a very new system and that there were going to be growing pains. Personally, I knew it was going to take time. It took years to understand windows and active directory. This was the next step. Now the only hard drives I fix are centralized!Windows flavors- thinPC is available through software assurance. It is vitial in my implementation. I have 9 esx servers running almost 300 images. I need every MB RAM I can get out of it. Pool Types- If you can afford View Premier, then you will have access to Linked-clones. If not you will need to adjust and utilize full images which I did for 3 years into my deployment. Not impossible at all.
  • -I had an instructor 5 years ago that said “ You will run out of RAM before you run out of CPU resources.” I didn’t really believe him, but he is still correct even in today’s world.I have tried almost every combination of clone storage in my environment and have found that local disks still work best for linked-clones (who cares if the machines that don’t have data on them are on non-redundant storage) Save the SAN for replica storage and server/data storage.I had many users state that they didn’t want the thin clients because “they heard about them” or I can’t listen to my music. You will have these users as well and some may be warranted, but I didn’t give me secretaries a chance. Administrators, I gave them a different type image rather than selecting a normal PC over a thin client. Stick to your deployment, otherwise you will never get done. All machines are now up-to-date, no more forgotten unsecure computers. Remember that I have 500 thin clients and half the virtual machines to fill them. Once you start you will find out how many machines are used at once. You may be surprised. I have reimaged my pools from my house with my 6 month old on my lap. It’s a nice option.-Utilizing the vShpere console I can multitask and be more efficient at my desk even interact with PCOIP sessions with the user logged in. I have less hair, but I am more useful to the district in this manner. Overall, your network performance should improve as your sessions move to a central location. I’ve trunked every connection into my ESX boxes and with distributed switches, the network could go down and the machines would still communicate.
  • It’s nice to know that when you decide to go with an enterprise product such as this, it will remain accessible from whatever OS you would like to use.All my administrators wanted a tablet when they came out, but there weren’t enough funs to support a desktop, laptop and tablet. So I mage a deal that if they turned in their laptop and desktop for a thin client, then I would get them a tablet and keyboard. Then they could remote in from wherever they like. Power savings- Utilizing the latest software and servers, you can fit more VM’s onto your existing servers so that you don’t need that extra server. Also, some of the latest servers adjust accordingly to demand. I know I notice when my older ones don’t during a power event. Never realized how much power they actually use when maxed out! Equallogic support is amazing at upgrading their software and firmware to improve performance on a 5 year old SAN. I once had a visitor to an openhouse laugh when I mentioned I planned to use that SAN for atleast 10 years. Halfway there! I’ve separated my storage network to mitigate any nuances. For instance, implementing jumbo frames and disabling spanning tree on your internal network would cause some headaches!- essentially a MSI program that allows programs to be installed to virtual machines without reimaging. If you set the thinapp to stream from a network server, such as a program like office, it only requires 10% of the entire program to actually be installed on the virtual clone. It actually runs the program quicker than if installed fully. To make the msi available to stream you must set it when creating the thinapp. As simple as changing a 0 to a 1 in an ini file.

  • The high school implementation Thin clients – can access 2 pools (basic and advanced) • Programs: Office 2013, Adobe CS4, Read Naturally, Autodesk, Visual Studio 2008, Microsoft Expression Studio 4, and Pennsylvania Keystone Exams 10 X90L laptops deployed in library • Programs: Study Island, Internet Research −Also used for edoptions for Alt Ed Students. −Run Windows XP Embedded Confidential
  • High school reactions “Virtualization coupled with Wyse thin clients have been a great addition to our technology in the high school. I, along with the students and staff have been surprised that they do extend the same capabilities as ordinary computers. So much in fact, that we do not even realize that they are not traditional PCs.” – Mrs. Diane Scarfalloto, High School Principal Confidential
  • The elementary implementation • Initial mid-year deployment of 50 thin clients into grades pre-K through 4. Currently, all labs utilize thin clients. • 2 thin clients allow reinforcement of materials that are taught in the lab • Network printers reside in central corridors of the hallways. (Location-based printing, determined by GPO and Subnet) Confidential
  • Elementary reactions “Teachers of Robert D. Wilson are more confident users of technology this school year than any other school year. The professional staff are more readily able to connect with web-based educational sites for instruction and program management such as Harcourt, Florida Center For Reading Research, Pennsylvania Department of Education and SRA- Scholastic.” –Mrs. Maria Miller, Elementary Principal Confidential

  • The reality • The ultimate solution is a mixed environment made up of laptops, advanced PCs, and thin clients • Accessories and multimedia delivery warrant a desktop machine in certain instances • It is possible to cut down on licensing due to the pooling of images Confidential
  • Lessons learned: possible issues • Location-based printing required in floating pools - Printer install on logon uses resources • User profiles greatly increase logon time, but take up storage. Takes time to perfect, but worth it! • Patience and Learning – Understand this is different and takes time for yourself to learn • Windows – ThinPC (no .NET) vs. Enterprise - Depends on user needs • Pool type – floating vs. persistent with linked-clone or full? Confidential
  • Lessons learned: all positives Content • Separate servers and classroom VMs style - Order servers with RAM (96 +) guidelines SANs with local storage for VMs - Leverage • Users really don’t know what they need in a workstation. - Stick to your deployment – don’t let them say no. • Classroom machines are always up-to-date now. - Reimaging takes hours and can be done from home. • Less hardware repair – Troubleshooting is virtual • Networking- endpoints can now be 100MB with GB uplinks. - Subnet often and utilize distributed switches. Confidential
  • Lessons learned: all positives Content style computing (BYOD) vast OS support • Mobile - View Client – Mac, iOS, Android, Linux, Kindle guidelines - Administrators tablets w/keyboards (pre-Surface) • Power-savings - With the latest servers, you can run more VMs • Support for SAN - EqualLogic firmware still improves my 5 year old SAN • Separate network for iSCSi SAN storage. - Less guessing during performance tuning • ThinApp common programs Confidential
