This is a live document, and questions will be expand and update over time.

EUC – End User Computing

Basic discovery

 1.  What is the expected type of EUC workload?

Why Ask? Are we talking about VDI (Full Desktop), RDSH (Shared Desktop), Application Virtualisation (like Citrix Apps or Horizon ThinApp).  Please keep in mind that you need to ask this question for every different workload the customer needs. In most EUC projects there is not just one type of user requirement. You will find a lot of mixed workloads, like persistent and non-persistent desktops as well as application virtualization.
VDI-Core licensing can help if the customer wants to run resource intensive VDI workloads, like developers or VDI with vGPUs and DR scenarios. For more information on VDI licensing check: https://docs.google.com/document/d/1VkFYvpOsAqmbwCwPWfGxg9bFhAmsPyANocn9rwG6eQQ/edit

 2.  Which vendor is used to manage and broker Desktops and Apps?

Why ask? The main vendors are Citrix, VMware, Nutanix. Every vendor has its own transport protocol, which makes a difference in CPU usage. Citrix = ICA, VMware = Blast or PCoIP, Frame = Frame Remoting Protocol.

3.  What is the expected Operating System Version?

Why ask? Every new version of Windows has higher requirements on CPU and Memory. It can make a big difference, if an older Windows version compared to the latest version. Windows 10 Performance Impact Analysis: https://portal.nutanix.com/page/documents/solutions/details?targetId=TN-2113-Windows-10-Performance-Impact:TN-2113-Windows-10-Performance-Impact

4.  What type of Windows license model is in use (KMS versus MAK)?

Why ask?Depending on the solution that is determined you may need to have one license model or the other (i.e. Frame requires KMS)

5.  What Office version is used?

Why ask? For Microsoft Office it is the same issue, like Windows versions. Newer versions need more resources.  Office 2019 Performance Impact Results from LoginVSI: https://www.loginvsi.com/login-vsi-blog/98-login-vsi/907-office-2019-performance-impact

6.  What other applications will be used?

Why ask? The applications used are having have a strong impact on the CPU. There might be single-threaded applications, which need high clock speed. Or you run applications that are multi-threaded and need a higher core count.

7.  What is the expected type of user?

Why ask? In sizer we ask for user types: task, knowledge, power user or developer. Every user type comes with a specific workload profile – memory, # vCPUs, vCPU:pCPU ratio, disk size. Sometimes the customer can give you details on the VM sizing, but not on the expected vCPU:pCPU ratio. Depending on the workload expected you can set the ratio. For more information read here: https://www.loginvsi.com/documentation/index.php?title=Login_VSI_Workloads

8.  How many concurrent users will you have on that workload?

Why ask? Concurrent user defines the number of active users. How many VMs need to run at the same time. Our VDI licensing is based on active VMs. You can have more users in an environment, but they can share resources, if they don’t work on the platform at the same time.  This can impact how you size compute and memory, but remember that storage may be needed for all possible users. 

9.  What provisioning method is used?

Why ask? Depending on the workload the VMs can be persistent or non-persistent. Persistent desktops will be treated like normal VMs. Non-persistent VMs will have a different storage footprint, since they are sharing a single boot disk and have additional write cache disks, which will be deleted after a VM reboots. Citrix uses MCS (Machine Creation Service) or PVS (Provisioning Service). VMware uses LinkedClones or InstantClones.

10.  Where are the user profiles stored?

Why ask? Using our own Files solution we can provide storage for the user profiles. Today you will mostly meet FSLogix profile containers, which still need an SMB share to be stored on and loaded during user logon.

11.  Do you need additional GPU support?  * (This may warrant engaging with a Solutions Architect or EUC Specialist for proper sizing and configurations)

Why ask? In order to accommodate applications like CAD or requirements in number of monitors and high resolution you need to add NVIDIA GPUs. An overview of vGPU Profiles can be found here: Virtual GPU Software User Guide :: NVIDIA Virtual GPU Software Documentation https://portal.nutanix.com/page/documents/solutions/details?targetId=SN-2046_vGPU_on_Nutanix:SN-2046_vGPU_on_Nutanix

 12.  Are there any other special requirements?

Why ask? Does the customer need RF3? Block Awareness, Rack Awareness, Storage encryption or replication)

VM Details

 1.  How many vCPUs?

Why ask? The number of vCPUs impacts the performance of the VM and the density of the host. Solution Engineering found the sweet spot to be at 3 vCPUs for a Windows 10 desktop or 8 vCPUs for Windows Server based Desktops

2.  What is the ratio between vCPU to pCPU?

Why ask? See question 6

3.  What is the requested CPU size per User?

Why ask? How much MHz does every user need to run the workload? It is very rare a customer can answer this. It is more common in application virtualization environments, since a number of users share the same VM and its resources.

4.  What CPU is currently in use?

Why ask? If the CPU currently used can handle, you could choose the same clock speed. But keep in mind in a virtualized environment resources are shared and you might have additional tasks running, like Files, which can impact the CPU.

5.  How much Memory is required per VM?

6.  What is the disk size?

Why ask? Depending on the provisioning method used you need the size of the Master Image (also called parental disk or Sandbox) and the Write Cache per VM. The write cache stores the temporary files written during the VM is active. For persistent VMs you need the disk size of the Master Image, which is then cloned into separate VMs.

7.  Are you planning to use microsegmentation to secure your VMs? If yes, what solution will be used?  * (This may warrant engaging with a Flow or Networking specialist or Solutions Architect)

Why ask? Position Flow on AHV or remember to size for a NSX appliance on every host.

8.  Are you planning on using an App layering solution?

Why ask? This saves the customer the need to manage lots of different master images. With App layering you have one master image and when a user logs the system will automatically attach additional disks, which contain the required applications. We can use shadow cloning to make those disks available locally.

General supporting Infrastructure

 1.  What Hypervisor are you planning to use?

Why ask? Different Hypervisors have different needs. If the customer chooses AHV we need to plan for PC, if it is VMware we may need to accommodate vCenter and for HyperV we need SCCM.

2.  Where will generic required services run?

Why ask? By generic services we mean AD, DHCP, DNS, Printing, licensing or application backend services. Some of them might be running in the cloud or on existing infrastructure. If running on the Nutanix Cluster take note of size and see Server virtualization questions.

 3.  Where will user profiles, home shares or App disks (if used) be stored?

Why ask? This is an opportunity to position Files. Usually customers today use a profile container to store user profiles. FSLogix is the most common solution used by customers, since it is included in their licensing. Please be aware that Files Services running on the same cluster do have a performance penalty during logon times.

4.  What is your DR strategy?

Why ask? Every customer needs a DR strategy for their EUC environment. A great question to position Xi Nutanix Clusters on AWS, replication and our unique VDI licensing approach.
Also need to calculate additional resources in your sizing, depending on the customers strategy.

Citrix Infrastructure

 1.  Where do you plan on running your Citrix services?

Why ask? Customers can choose to run all Citrix related services (like Studio, Databases, Storefront) as service in the cloud, managed by Citrix or on premises. If the customer chooses to run the services on premise, he can still run it on a different infrastructure. If he chooses to run it on the same cluster, please size additional server virtualization VMs. Guidelines on VM requirements can be found here: https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/system-requirements.html
If the customer chooses Citrix Virtual Apps and Desktop (CVAD) Service you still need an additional Windows server as Cloud Connector.

A typical on premise implementation would need the following servers:
SQL deployment. What type of HA? (Always On, SQL Clustering with WSFC)
StoreFront Servers (HA, N+1)
Citrix Desktop Studio and Director (N+1)
Optional Provisioning Server (PVS) (N+1)
Network Load Balancer
Global Server Load Balancing
Profile Management Infrastructure (File services)
AppLayering Infrastructure
Any Endpoint Management technologies?
Failure domain sizes (Prism Central sizing)
Dedicated Infra Management Cluster or part of the Citrix cluster

VMware Infrastructure

1.  Where do you plan on running your VMware Horizon View Services?

Why ask? Customers can choose to run all Horizon related services as service in the cloud, managed by VMware or on premises. If the customer chooses to run the services on premise, he can still run it on a different infrastructure. If he chooses to run it on the same cluster, please size additional server virtualization VMs. Guidelines on VM requirements can be found here: https://docs.vmware.com/en/VMware-Horizon-7/7.12/horizon-installation/GUID-858D1E0E-C566-4813-9D53-975AF4432195.html

A typical on premise implementation would need the following servers:
SQL deployment. What type of HA? (Always On, SQL Clustering with WSFC)
Unified Access Gateway Appliances (N+1)
vCenter (N+1)
Horizon Connection Server (N+1)
Optional View Composer (N+1)
Profile Management Infrastructure (File services)
AppLayering Infrastructure
Any Endpoint Management technologies?
Failure domain sizes (Prism Central sizing)

Xi Frame Infrastructure

1.  Will there be Xi Frame User VMs on premise?

Why ask? For the use of Xi Frame on premise you need to add additional server VMs.
Cloud Connector Appliance (CCA)
Secure Gateway Appliance (SGA)

2.  Do you currently use Prism Central today and does it run in the same Prism Element cluster where the Frame workloads will run?

Why ask? Prism Central is required for Frame workloads for on premises Frame deployments

Advanced Discovery

1.  How do you optimize your image?

Why ask? Image optimization is crucial in all EUC environments. The host density and the user experience is increased by optimizing the VM using the tools provided by Citrix, VMware or vendor independent.
Citrix: https://support.citrix.com/article/CTX224676
VMware: https://flings.vmware.com/vmware-os-optimization-tool

2.  What is your Antivirus Strategy?

Why ask? The right AV solution can also have a massive impact on user experience and host density. If not done correctly all file operations lead to file scans, which increase CPU and IO on the host.

Why ask?  This helps determine what their workload profile is like and how it will affect our platform (reads are local, writes incur node replication cost) as a baseline.

5.  What is the SQL Server average IO size?

Why ask?  This helps determine what their workload profile I/O size is related to bandwidth .

6.  Top current SQL Server wait statistics during peak workload?

Why ask?  This helps determine what SQL Server is waiting on to process transactions, where there may be a bottleneck.

7.  Current customer Microsoft SQL Server pain points?

Why ask?  This helps narrow the focus and develop a relationship with the customer.  It also assists in focusing on how Nutanix can help alleviate those specific pain points and gives information about how the solution can be shown to resolve those particular pain points.

Oracle

 1.  License Entitlement  ( Cores/NUPS/ELA/ULA/bundled licensing)?

Why ask?  Oracle licensing is expensive and customers want to make the best use of their entitlement when replatforming and not spend more $$ on new licensing when doing a new solution.  Customers are also looking forward to reducing their Oracle License overhead .

2.  Type of Licensing used? :  STD / Enterprise and other options (RAC/Partitioning …etc.).  Each is a paid item.

Why ask?  There may be possibilities to eliminate some Options by using Nutanix Features such as Compression, Encryption, Replication

3.  Is the customer ready to run a “SQL script” or provide details of the environment using RVTools/Collector?

Why ask? When inventorying an Oracle DB environment, you can use the Automatic Workload Repository (AWR) report to gather detailed inventory and performance statistics for an Oracle Database.  Nutanix has an AWR script that can be run to capture the necessary information and is able to be downloaded from within the Sizer Tool.  When adding a Workload select Import, then click the AWR tab and you will see the AWR SQL Script download link.  Once run, you can then upload the output using the Upload File option.

4.  What are the main pain points in the current environment?

5.  When moving to Nutanix would you consider AHV as a hypervisor?

6.  Have you been introduced to Era?

Era

1.  How do you do DB provisioning today and how long does it take to provision a multi-node database cluster?

Why ask :  To find out customer operational efficiency for provisioning . Era can help improve this from weeks to hours.

2.  How many dev/test copies of databases do you have for a your PROD instance(s)?

Why ask : Customers make multiple “full copies” of PROD for test-dev dev/test and use up to 5-10 times the space they need . Era will help in creating space optimized clones of database with “rapid speed”  

3.  What is your typical clone refresh interval and time it takes to refresh a DB clone?

Why ask: Customers using traditional techniques to refresh a copy of a database from a RMAN backup , takes multiple hours and is usually done once a month .  With Era , they can clone everyday or multiple times a day in minutes.

4.  How do you do your Database Patching (Oracle)?

Why ask :  Oracle patching is a huge pain point in large Oracle environments. Era provides a unique way to do “fleet patching”  which will help save 100’s of man hours spent in traditional patching

5.  How do you migrate Databases when required ( Oracle)?

Why ask : Migration is an involved process and a lot of planning and time is required for migration.
Era provides an easy method to “replicate & migrate” databases (Same version) for same-endian formats. ( Linux->Linux or Windows ->Linux)

6.  What is your choice of  Database Replication  (infrastructure/database/hypervisor based)?  Please elaborate.  * (Depending on the complexity of the environment, this would warrant further discussion with a Database Specialist/Solutions Architect)

Why ask:  customers are looking to reduce their software licensing cost of database replication and will look for opportunities to replicate using infrastructure (nutanix replication) . era enables cross-cluster replication including replicating to a NTNX cluster in AWS cloud in an upcoming release 2.0

7.  What are the database engines they currently use?

April 27

Hi everyone

Hope all is well at end of quarter. We did release a new sprint with some nice enhancements-

  • Mine can now have Objects as it archive. So you can put a lot of the archive data on cheaper storage. Screenshot below. You can adjust the mix of how much to put on Mine vs Objects
  • AMD sizing is ready … well whenever we have AMD models. Ratan worked through lot of narly stuff to get this ready and wanted to plug his efforts and good that Sizer is ready
  • NX – 12 cores rule for 12TB HDDs are there
  • DX – added the gpu cables and the Trusted Platform Module (TPM to the BOM).  We are pretty complete on offering full BOM for DX now
  • VERY COOL department…
    • Go to a workload and scroll down and you will see on your left a menu with the sections that scroll with you (attached). Sizer in last couple years has way more stuff in a workload and so resulted in lot of scrolling, but now we made it easy to go all round
    • Manual sizing UI is nicer now too

April 13

  • New edit/add workload page –  We want to introduce new functionality as we develop Sizer Basic and Advanced. We are now offering our new workload page. It is easier to select what you want. Hope you like it and describe it below·
  • N+1 yellow indicator. When we do an auto sizing or you do a manual sizing we let you know if the resiliency is N+0, N+1., or N+2.  Most people shoot for N+1. What we do is under the covers is remove a node and go through all the sizing rules and equations and make sure indeed it is less than the N+0 threshold (for example for CPU that is 95%). That is all good but you can be close and so we wanted to let you know. Using the CPU example if within 5% of the n+0 threshold we keep it N+1 as technically it is but turn it yellow.  Given sizing is lot of estimates it is best to have some margin for error and let you all know your close to the edge.·
  • Migration for VDI Display protocol –  Display Protocol was added recently as an input for VDI sizing. The VDI gurus felt it was needed going forward. It is very expensive though adding 40 to 45% on cores. While this is valid sizing this could break any old sizings. So in older sizings it will default to None·
  • Mine licenses updated

GREAT NEWS

We have Frame for AHV live in Sizer

As mentioned in the town hall,  EUC and in particular Frame for AHV is a hot market in extremely difficult times.  We were working on it but pulled it in.    We always want Sizer to enable you guys to do the amazing work you do.  In these times though, we will acutely focus on solutions that are  really hot right now.  I see improving upsell (replace or increase nodes in existing clusters) as next focus.

Very simple to use if you are familiar with VDI in Sizer (which is one of top workloads and so presumably you are).    Frame for AHV is simply a different broker and the display protocol is selected.  All the other options are the same.Beyond enabling it in the tool, we will soon add licenses to make that easier to quote (we have AOS and the HW now).  We will also enhance collateral with the solution as time goes on.Hope you like … let us know.  Attached is short video

Hi gang

We are actively building out Sizer Basic and Sizer Advanced.  Sizer Basic for customers, reps, other non-technical folks who want a sizing and just go with the default profiles.  Sizer Advanced will offer the SE much more advanced functionality for multiple workloads, multiple clusters, etc

As we build those out we want to get some of the functionality out in Sizer when available.  Today we introduced Workload Filters.  We see a workload where with Collector you may have a hundred workloads and finding what you want will be hard.  Enter the filter where you can filter by workload name, workload type, number of VMs. cores, RAM, SSD (either less than or greater than a value ), status (enabled/disabled).

Examples

  • Show me just workloads of certain type (e.g. VDI)
  • Show me workloads that have min or max of so many cores (could be RAM, HDD,SSD)
  • show me just enabled workloads
  • show me ones with certain name string or partial string
  • Combine all the above

This will ultimately be accompanied with BULK EDITs.  So find me all the VDI workloads with certain name string and change profile to Power User for example. Here is screen shot (edited)

 

March 16

We did come out with new Sprint last night

Backup  is now a  regular primary workload like VDI, Server Virt, etc (see below).  It had been a target for existing workloads but now Backup can be a primary workload where you figure out the backup requirements if the customer is just wanting back up some data from some other systems beside Nutanix

12TB HDD/min12 cores

Partial population rule for Nutanix with 1.92TB SSD

NX: 128GB with mCPU, LCPU

various updates for Dell XC

Great to see so many of you at GTS America

We did go live with the new sprint.

Now have full BOM for HP DX.  Why that is important is as you go to the HP store to place a quote you will have full information you need including the power supply for example.  At GTS, people asked about us making a call to the HP store.  Unfortunately they don’t have a API we can call.  We will work on making it easier though with a link from Sizer We did do The cascade refresh CPUs but not live in Sizer yet.  I would expect those in next 2 days

Hi everyone

I am at GTS Americas.  Hope to see lot of you.  I have a presentation tomorrow with the Partners and one on Thursday with NX field.

  • A lot of very cool things are happening in the Sizer area which I’ll discuss in these presentations but here is the summary.
  • Collector 2.2 is out but coming is Collector Portal which allows customer to share their collection much easier than with Excel
  • Sizer Basic is in the works and should be out this qtr.  This is streamlined for volume sales and will be available to customers.  We have had a customer program for some time which has been a success and this will be cool.  Think about collaborating with the customer on sizing.  I’ll talk more
  • Sizer will get a lot more advanced.  We are moving to multiple clusters and ability to have different sizing for each cluster and for each cluster to adhere to different policy.  Auto will provide 3 options – low cost, high performance, and high cap .  Wow lot of options to play with
  • Ok if that was not enough we are working on Sizer Xpert.  Sizer today is deterministic.  You want replication, RF3, Era, yada yada, by golly Sizer can do it to the 4th decimal place.  Well great if you know that is what you need.    Working on Xpert that will review your solutions and prescribe ideas.  We worked on it at hackathon and now in development.  hope to see a lot of you this week and please do reach out if want to meet 1 on 1.  Ratan Kumar will be in EMEA GTS later next month.  We will cover APAC one too

Server Virtualization

What is a Server Virtualization sizing? 

This is the most common workload along with VDI. This can be used for any web app which needs to be sized. Each workload or the application which is to be migrated to the Nutanix software stack is a VM with its own CPU/RAM/Capacity requirements. To simplify for the users, Sizer has set profiles (small,medium,large ) for the VMs but customizable as per the actual application needs.

 

What are profiles in Server Virtualization in Sizer?

Profiles are fixed templates with pre assigned resources in terms of vCPUs, RAM, SSD, HDD to each profile. Broadly, small, medium,large profiles will have different allocation of these resources.

The idea is to facilitate users with the details of a workload (that is a VM)  so they cna quickly fill in number of VMs and Sizer will do the necessary sizing.

Small VM profile template:

Medium VM profile template:

Large VM profile template:

 

What if my VMs are different? Have differen values? 

While these templates and their values are general guidelines, these are customisable.

Clicking on the Customize, opens a  pop-up for user entered values:

January 2020 Sprints

January 21

Collector

  • Collector or RVTools –  Can now size for just powered ON VMs or both Powered ON and OFF VMs. Was just Powered ON.
  • Collector or RVTools profile can go up to 64GB RAM (was 32GB)

Usability

  • Rich Text Format is now available for  Scenario Objectives. So you can bold things or underline words in the Objectives to make a key point.  This also makes it into the BOM and so a  nicer document

January 31

Products

  • Complete HPE DX BOM.  Now Sizer will provide a complete BOM including chasis, power supplies, etc.  This makes it easier and reduces potential errors when quoting HPE DX models on HP’s configurator.
  • Update to 8155-G7 product rules

Workloads

  • Allow for 240TB per node for Objects Dedicated workloads.   Since it is Objects Dedicated workloads other applications are not allowed
