The paper describes provides the architecture and design of a virtual desktop infrastructure that can grow from 500 users to 1000 users. The infrastructure is 100% virtualized on Microsoft Hyper-V Server 2012 with third- generation Cisco UCS B-Series B200 M3 Blade Servers iSCSI booting from an EMC VNXe3300 storage array. The virtual desktops are powered using Citrix Provisioning Server 7 and Citrix XenDesktop 7, with a mix of hosted shared desktops (70%) and pooled desktops (30%) to support the user population. Where applicable, the document provides best practice recommendations and sizing guidelines for customer deployments of XenDesktop 7 on the Cisco Unified Computing System.
VMware last week released a new version of the Horizon View clients for Windows, Mac, Linux, iOS, and Android. Customers using a View client on their device are able to access their Windows desktop hosted on a VMware Horizon backend infrastructure.
The following functionality was added in version 2.3:
Microsoft has updated the capacity planner for Hyper-V Replica tool first relased in May 2013. The updated version offers the following:
Support for Windows Server 2012 and Windows Server 2012 R2 in a single tool
Support for Extended Replication
Support for virtual disks placed on NTFS, CSVFS, and SMB shares
Monitoring of multiple standalone hosts simultaneously
Improved performance and scale – up to 100 VMs in parallel
Replica site input is optional – for those still in the planning stage of a DR strategy
Report improvements – e.g.: reporting the peak utilization of resources also
Improved guidance in documentation
Improved workflow and user experience
In addition, the documentation has a section on how the tool can be used for capacity planning of Hyper-V Recovery Manager based on the ‘cloud’ construct of System Center Virtual Machine Manager.
These posters provide a visual reference for understanding key private cloud storage and virtualization technologies in Windows Server 2012 R2. They focus on understanding storage architecture, virtual hard disks, cluster shared volumes, scale-out file servers, storage spaces, data deduplication, Hyper-V, Failover Clustering, and virtual hard disk sharing.

We are excited to announce the General Availability of Hyper-V Recovery Manager or HRM for short. HRM is an Azure hosted service which orchestrates the protection and recovery of virtual machines in your datacenter. Hyper-V Replica replicates your virtual machines from your primary datacenter to your secondary datacenter. To re-emphasize, your VMs are not replicated to Windows Azure. HRM is a service hosted in Azure which acts as the “control plane”.
In summary, the root account of the vCenter Server Appliance version 5.5 becomes locked out 90 days after deployment or root account password change. This behavior is by design which follows a security best practice of password rotation. In this case, the required password rotation interval is 90 days after which the account will be forcefully locked out if not changed.
The KB article describes processes to prevent a forced lockout as well as unlocking a locked out root account.
Approximately 90 days have elapsed since the release of vSphere 5.5 and I imagine this issue will quickly begin surfacing in large numbers where the vCenter Server Appliance 5.5 has been deployed using system defaults.

Last week I ran into another discussion about the hypervisor under a XenApp deployment it had to be free or very cheap. So the customer was thinking about loading Hyper-V below it. Ok can be a viable option but the admins hoped it would be VMware ESX because they know that hypervisor and it has never let them down in the past six years. So I got the question what is possible, can we use the Free vSphere Hypervisor? I than remembered from VMworld San Francisco 2013 the limitations of the Free vSphere Hypervisor have been lifted.
So now you can use the vSphere Hypervisor 5.5 with:
Unlimited number of cores per physical CPU
Unlimited number of physical CPUs per host
Maximum eight vCPUs per virtual machine
But most important the limitation of 32GB RAM per server/host has been removed from the free Hypervisor.
So now you can use it below a XenApp deployment or in a stack where you do not need DRS, HA and vMotion. If you do need a central management solution you can use the Essentials Kit and if you need DRS, HA, vMotion etc. you can use the vSphere 5.5 essentials kit it is for max. 3 servers with 2 physical CPUs per Server.
In Europe the Essentials Kit will cost 690 Euro for 3 years and the Essentials Plus Kit will cost 5.554 euro for 3 years. If you want to have support on your VMware vSphere Hypervisor you can now purchase Per Incident Support for it.
