What is Diskless VDI?

Diskless Virtual Desktop Infrastructure (VDI) is the concept of using local server memory in combination with storage optimization software to store virtual desktop images instead of shared SAN/NAS or local SAS/SSD storage.

By storing virtual desktop images on the local memory of the hypervisor where the desktops execute, response time are faster than even the most expensive local SSD drives (MLC or SLC), cost less when combined with Atlantis ILIO, and increase reliability.

With existing VDI architectures, virtual desktop images are stored on either shared SAN/NAS storage or local SSD disks, which are costly, have limited IOPS for write-intensive VDI workloads, can have a limited lifespan and consume more power than memory.

VDI

Benefits

  1. Software only – Atlantis ILIO Diskless VDI is a purpose built storage layer to run virtual desktops with just CPU and RAM and no other storage or SSDs. Scale-out VDI infrastructure with just servers and software.
  2. Amazing user experience – 300+ IOPS/user* – faster than PC user experience  even with iPads.
  3. CAPEX below $200/user – infrastructure cost under £125 per desktop including the server hardware, RAM and Atlantis ILIO.
  4. Lower OPEX – Enable lower operating expenses by eliminating rack space, power consumption, cooling and repair costs, and daily operational tasks of maintaining disk-based storage.
  5. Automated multi-rack deployment – Automatically install and configure ILIO on hundreds of servers across dozens of racks. Creates and registers NFS data stores that are ready to use by the VDI broker to complete the provisioning process.

VMware Welcomes Wanova to the EUC Family

VMware Welcomes Wanova to the EUC Family – Office of the CTO | Office of the CTO.

Wanova Mirage is an innovative image replication and layering technology that combines sophisticated, layered image management with client-side execution and persistent caching. It was designed to centralize the management of desktop images in the data center and to deliver those images efficiently to physical Windows systems for a native user experience, as well as to virtual machines for execution.

VMware can leverage Wanova’s replication technology to allow disk images to be replicated to VDI host servers meaning you wouldn’t need centralized SAN storage for VDI.

VMware Workstation 8 Released

What’s New

This release of VMware Workstation adds the following new features and support.

Installation Changes and Enhanced Keyboards

The hardware requirements to install this version of Workstation have changed. Workstation now requires a relatively modern 64-bit CPU.

The keyboard filter driver is no longer installed by default.  When the driver is not installed, the enhanced keyboard functionality is
unavailable and you must press Ctrl-Alt-Ins instead of Ctrl-Alt-Del to send a Ctrl-Alt-Del keystroke to the guest.

Virtual Hardware Improvements

New display technology

VM can support up to 64GB RAM.

HD audio

USB 3.0

Bluetooth

Use Virtual VT-X/EPT or AMD-V/RVI for VM’s needing
64-bit OS.

New User Interface

Virtual Machine library

Folder summary page

Full screen toolbar

What Happened to Teams?

Team structure converted to folder of VM.

Power operations to multiple machines as same time.

Global preferences for delaying power on VM’s.

Shared Virtual Machines and AutoStart

You can share virtual machines with remote users in this version of Workstation.

You can use the new AutoStart feature to configure shared virtual machines to start with the host system

Remote Connections

You can use the new Connect to Server feature to connect to remote hosts running Workstation, ESX 4.x and later, and VMware vCenter Server.

Upload to vSphere

VMware OVF Tool is now integrated with Workstation so that you can upload a virtual machine from Workstation to a remote server running ESX, ESXi, or vCenter Server. After connecting to a remote server, you drag the virtual machine from the local My Computer section of the virtual machine library to the remote server. A wizard walks you through the process.

Installation Requirements

When you install Workstation, the installer performs checks to make sure the host system has a processor that meets the following requirements. You cannot install Workstation if the host system does not meet these requirements.

  • 64-bit x86 CPU
  • LAHF/SAHF support in long mode

You can use CPU-Z or a similar utility to determine if the host system CPU is 64-bit capable.

CPU-Z shows EM64T (Intel) or AMD64 (AMD) if the processor is 64-bit capable.

If you plan to install a 64-bit guest operating system in a virtual machine, the host system must have one of the following processors.

Workstation will not allow you to install a 64-bit guest operating system if the host system does not have one of these processors.

  • AMD CPU that has segment-limit support in long mode.
  • Intel CPU that has VT-x support. VT-x support must be enabled in the host system BIOS.
  • The BIOS settings that must be enabled for VT-x support vary depending on the system vendor. See VMware KB article 1003944 for information on how to determine if VT-x support is enabled.
