Citrix Applayering and Prism Central 5.5 issues
Specs: Citrix App Layering Version: 4.11 AOS: 5.5 Prism Central: 5.5 We are running into an issue when creating new app layers and platform layers after upgrading to 5.5. If I disconnect our clusters from prism central, the creation process works. The app layering appliance appears to have issues creating a packaging VM on the nutanix clusters as prism central is now managing the CRUD operations, as opposed to being managed strictly by the cluster. The error message we get in app layering is: The Nutanix server has encountered a failure processing the request: (500) Error: Internal Server Error, Details: Error occurred while creating Disk Image I'm not the most familiar with the low end nutanix platform, and where to search for logs, but it appears to be caused by the centralized image managed, or the centralized VM management function of prism. Has anyone else ran into this issue, or possibly know when this will be fixed? Citrix's response is lackluster (as usual), a
AHV + Unidesk(now Citrix App Layering) performance
I was wondering if anyone has used Unidesk on AHV? I am up to date on both (Unidesk 4.6, not 4.7). It takes about 45 minutes to edit a layer, then another 45 to finalize, frequently longer. Data rates are usually between 80 megabytes/s and 120 megabytes/s. The rates will spike up to 1.5 gigabit, and I have looked into the link rate, which shows as 10gbit in the console. I don't think it is hitting a 1 gbit barrier (unless there is traffic management within nutanix I am not aware of). What I have investigated: Link Speed - referenced the link speed in the prism network UI, shows correct, also spikes above 1 gbit regularly, occasionally holds above 1 gbit by a bit Load - I have also tested this when the cluster is under load and when it isn't. This doesn't have discernable impact on the performance. Multiple jobs - I have started multiple jobs in the Unidesk console, the total write speed was about the same as when it is doing a single job, and after about 6 simultaneous jobs it starte
Thoughts & Recommendation for multiple NICs, VMware ESX servers, & Nutanix
We are in the process of evaluating HCI Platforms. We plan to run VMware ESX server on Nutanix HCI for a VDI solution. Currentlty running VDI solution on Citrix and Cisco UCS now. The end solution will support roughly 3000 - 5000 users. I would like to get any thoughts and recommendations on the topic of the number of 10-GB NICs to have on the Nutanix HCI platform, per node. Most HCI platforms are sold with two physical NICs. Obviously, this makes it hard when using multiple NIC's in VMware to protect important traffic - specifically, the management and IP storage traffic. Where in UCS there might be 6-8 NICs on an ESX server - 2 x for Mgmt, 2 x for vMotion, 2 x for IP Storage, and 2 x for Guest VMs - this gets consolidated on to two NICs in a Nutanix node. I understand this will work, but, is it a better practice to use multiple and separate physical NICs in Nutanix to isolate VMware traffic and functions to ensure each function has bandwidth? In short, for VMware on Nutanix
Citrix MCS shadow clones on Metro Availability
Hi guys, finally after 6 years I can update our XenApp farm from 6 on win2k8R2 to 7.15 LTSR on Win2k12R2. I've read this good post of how Citrix MCS or PVS can leverage the Nutanix shadow clones: [url=https://next.nutanix.com/t5/Nutanix-Connect-Blog/Citrix-MCS-and-PVS-on-Nutanix-Enhancing-XenDesktop-VM/ba-p/3489]https://next.nutanix.com/t5/Nutanix-Connect-Blog/Citrix-MCS-and-PVS-on-Nutanix-Enhancing-XenDesktop-VM/ba-p/3489[/url] My enviroment is 2 Nutanix cluster on metro availability on 1 vmware stretched cluster. The question is, how MCS can works in this scenario? I need 2 master image, one per Nutanix cluster? Because with only one master image I can't leverage the caching/data locality of the VM in the second cluster and vice versa. Thanks!
New Nutanix nodes for Horizon View 7 environment
I am ready to proceed with a new Nutanix cluster consist of 4 nodes. I am a bit confused on containers , NFS, and VMFS. To run an effective View 7 environment on this new cluster, 1. Should I Create Containers and present them to ESXi ? (This will be NFS) 2. Should I create ISCSI Volumes? is that supported? 3. Any additional suggestions? We have been running a solidview environment for a few years in a traditional ESXi hosts with linked clones and persistent and non persistent Virtal desktops. Thnak you for any help in advanced.

Horizon View on AHV, is support possible?
I currently have a 10 seat Horizon View Enterprise 7.2 POC and I am currently using ESXi. I would really like to switch to AHV but from my understanding this would not be supported by VMWare correct? If not surely others are running Horizon View on AHV and if so how are they dealing with any support issues they may encounter with Horizon problems? My second hiccupp would be that I am a Dell XC customer so I guess if I had any Horizon problems then I guess they would relay the support case to Nutanix?
Citrix PVS Support for AHV
Hello, i think about Citrix PVS on Nutanix All-Flash Blocks with Acropolis Hypervisor. But there is no offical support for AHV, which means that i have to run VMware or Hyper-V on my Nutanix Cluster to use PVS. -> [url=http://support.citrix.com/article/CTX202032]http://support.citrix.com/article/CTX202032[/url] Is there any roadmap for this?
Citrix XD 7.13 / vCenter / Prism - MCS fails to create catalog.
Hi guys, Deploying full clone VDI on XD 7.13 with Studio linked to the vCenter appliance (5.5 u3e). Prism (5.02) sits behind that on Dell boxes with vSphere environment on top of that. New environment. All storage containers/nodes/etc have unique names. We don't have an issue deploying targets in vCenter manually. We have all the XD infrastructure components running without issue. If we create a new MCS catalog, the VMDKs get copied during the , but right after the copy of the base disk to the data store, the MCS wizard fails. Error Id: XDDS:0DAA3833 Exception:Citrix.Console.Models.Exceptions.ProvisioningTaskException An error occurred while preparing the image.at Citrix.Console.PowerShellSdk.ProvisioningSchemeService.BackgroundTasks.ProvisioningSchemeTask.CheckForTerminatingError(SdkProvisioningSchemeAction sdkProvisioningSchemeAction)at Citrix.Console.PowerShellSdk.ProvisioningSchemeService.BackgroundTasks.ProvisioningSchemeTask.WaitForProvisioningSchemeActionCompletion
VMware Horizon Async DR
Hi,we are running 20 Nutanix Nodes with AOS 5.0.1 and ESXi 6.0 as hypervisor splitted into 2 Clusters (10 Nodes per Cluster) which are running in two different vCenter (vCenter Server Appliance 22.214.171.12400 Build Number 4632154) and two different locations.Now we are testing Nutanix Async DR to test failover from one side to the other side. All VMs will be shutdown successfully and will be migrated (unregistered at the local vCenter Server and registered at the second vCenter Server) successfully to the second vCenter.The Issue is, that VMware Connection Server, which is connected to both vCenter Server, will not recognize that the VM have moved from one vCenter to the other. So it is not possible for us to connect to this VDI on the second side.Can anyone assist us find a solution for this problem?Best RegardsMarkus
Use iSCSI for a VDI environment
Hi, We are thinking of building a separate VmWare Horizon view cluster and make the Nutanix-cluster used just for server loads. We have a few scenarios of creating this. And one is to buy 4 new vmware hosts and connect them to the existing nutanix cluster with iSCSI, this is just because we have enough storage already in the existing cluster. My question is, will it be a bottleneck to use iSCSI? We will run about 260 Win7/Win10 task-workers VDI clients. Regards Tobias
OS Gold Image Best Practices | NTFS Allocation Unit Size
I've been doing some research on best practices when creating a gold OS image for VDI. Some vendors (e.g., EMC) recommend using 8k vs the default 4k with Windows 7. Obviously this has a lot to do with vendor based storage and overall design. Is there a specific OS NTFS allocation unit size Nutanix recommends when staging a gold image based on Nutanix storage technology? Any thoughts would be appreciated.

Convert Windows Development Image to Acropolis
Anybody figured out how to convert or modify a Windows Developer image (these ones: [url=https://developer.microsoft.com/en-us/windows/downloads/virtual-machines]https://developer.microsoft.com/en-us/windows/downloads/virtual-machines[/url]) to run on Acropolis? Looking to allow these builds to simplify some Developer testing being as they're updated about monthly by Microsoft and include the tools necessary to work within them. The flavors are Hyper-V, VMware, Parallels and VirtualBox. I quickly attempted uploaded the vmdk from the VMware version, but of course get bitten by the virtIO driver necessity with Windows. Trying to review options to copy the drivers into the disk or something, just starting to research. Point being, building from scratch isn't what I'm interested in, I want to be able to simply pull down this image (OVA, OVF, VHD, VMDK) and convert it to KVM/Acropolis...if possible.
Solved: OSD via SCCM problem
Hello, i ran into an error with my OS-Deployment via SCCM on my AHV cluster. I apply the Nutanix related drivers in the Tasksequence with following query: [b][i]Select * from Win32_ComputerSystem Where Model LIKE "KVM"[/i][/b] This worked for me all the time. After i migrated the cluster to AOS5.0 this step is skipped in the tasksequence with a message that says that this condition is FALSE. Could it be, that a newly created vm an a AOS5.0 based cluster displays another Model?My running vms on this cluster still show KVM as modul, so i'm a little bit confused.
iSCSI container and Controller Avg I/O Latency
We have iSCSI container of 14TB created and presented to MSFT FS cluster using EXTERNAL DATA SERVICES IP ADDRESS. Network - 10Gbps, VMs are in same Nutanix Cluster and ESXi 6.0 is the Hypervisor. 39 node cluster I am seeing Controller Avg I/O Latency of 100+ms. Is this normal!?
Adding automatically static Horizon desktop to protection domain
Hello, i've realized a project with two nutanix cluster and Horizon VDI with static desktop.Desktop are replicated with protection domain between two sites. Someone know if in Nutanix there is a method to add automatically desktops to a protection domain? Thank you and best regards Luca
20K to 200K+ VDI Desktops on Nutanix
Subsequent to the recent VDI Assurance program announcement I published a blog article about what an infrastructure to support 20K to 200K+ Power User desktops might look like on Nutanix. I thought this might be of interest. Not only is this solution incredibly space efficient, what you see is the complete server, storage and network required, but it's also incredibly power efficient. With the new Nutanix VDI Assurance Program it makes any scale VDI even more accessible and beneficial to everyone.
Write latency in a VDI POC
We are performing a POC at a customer site using a 3 node DELL XC720xd cluster. The statistics taken from Vcenter show an average read letency around 1 ms and a write latency aroud 5-6 ms. The write latency seems way too high since it should just make 2 writes (base and replica) on SSD. I wonder if the CVM has a timer before it flushes the pending writes to the oplog. This could help generally speaking to reduce the number of I/O and increase the size which is good for SSD. Unfortunatey in our POC we are fighting against the current configuration of server with Fusion-IO PCI cards and this approach could be a disadvantage. Another important parameter is the logon time which average at 35-40 sec on the current system and goes up to 75 sec with Nutanix. Any suggestion to speed up the Nutanix Cluster may be modifying some parameter?
Choosing the right XenDesktop Version
Hello there, i'll do my first project on a Nutanix platform and need a little hint. We normaly run XD7.6 LTSR for our sites but i'm not sure about Nutanix MCS integration on this on so far. With 7.9 there is an integration for Desktop Studio after installing the Nutanix plugin. Any possibility to get such an integration for XD7.6? If not. Do you think 7.9 will be the better way? I guess it will be.

Best Practices for Horizen View
I see that the Best practices for Horizon View (V2.7.2 August 2014) was written for Horizon View 5.3, on page 19, it is suggested to use "KB2914680 - I/O delays in windows 7 SP1 or Wndows Server 2008 R2 SP1" if creating user profile or user data on a file server. My question is does this still apply if we are running Horizon View 6.1.0? I'm having persona isues and was wondering if this KB2914680 still applies to my version.
