Cut VDI CAPEX by 50-75%


Cut VDI CAPEX by 50-75%

  • Use Less Storage—cut the amount of VDI storage required by up to 90%
  • Scale VDI Storage—support 5 to 10 times the number of desktops on the same storage with equal or better performance
  • Use Any Storage —use lower cost SAN, NAS and Local Disk (SATA, SAS, SSD)

Boost VDI Performance

  • Desktop Performance—make desktop boot, login, and application startup perform faster
  • Accelerate Application Virtualization—accelerate virtualized applications for VMware ThinApp, Microsoft App-V, and Citrix XenApp App Streaming to improve logon times for non-persistent desktops and launch times for virtualized applications

Inline Deduplication

Atlantis ILIO transparently offloads write operations before they reach the storage fabric.

  • VDI Storage IOPS Offload—up to 90% reduction in IOPS load on storage infrastructure
  • VDI Storage Capacity Reduction—up to 95 % reduction in disk storage capacity requirements
  • VDI Latency—accelerates VDI performance by eliminating disk write latency

Windows NTFS Protocol Layer Processing

  • Hyper-efficient IO characterization—instantly characterizes IO based on Windows NTFS file system characteristics
  • Faster IO Processing—real-time IO processing locally from memory
  • IO Optimization—re-sequences read/write operations from small random IO to large sequential

Integrates with Leading VDI Solutions

  • Certified Interoperable—VMware View Technology Alliance Partner and Citrix Ready Partner
  • Leverages Existing Infrastructure—VDI brokers, application virtualization, profile virtualization, and image layering tools
  • No Desktop Changes—doesn’t require an agent or any change to the desktop image
  • Deployed Using Open Virtualization Format (OVF)—easily installed in 8 minutes as an .OVF virtual appliance

vSphere Myths

Over my time using VMware vSphere, I have always seen recommendations and best practices from other IT professinals and blogs, and there are a lot of myths hanging around, and the most common myths are:-

1) Defrag your Guest OS disks for best performance

2) E1000 is faster than VMXNET3

3) CBT causes significant overhead on your VMs

4) HA datastore heartbeats prevents host isolation

5) LSI SCSI is always better than Paravirtual SCSI

Eric Sloof (NTPRO.NL) discusses this and busts the myths on the following site  :- http://www.ntpro.nl/blog/uploads/Mythbusters_Dutch_VMUG.pdf

Download the pdf  by clicking this link :- Mythbusters_Dutch_VMUG

The outcome of the myths that were busted was :-

1)  Use disk defragmentation tools with caution

2)  Use VMXNET3 wherever possible

3) CBT has very little overhead

4) HA datastore heartbeats are used as a communication channel after management network outage

5) PVSCSI is equal or faster and requires less resources than LSI SCSI

VMware vSphere interoperability

Before you plan to ugrade to vSphere 5.0, check out the interoperability tables below.

As an example, you may go ahead an upgrade to vCenter 5.0, but vCenter 5.0 will not work with SRM 4.1, so therefore you will have to plan the upgrade very carefully so that any existing systems to not get affected.

vCenter + SRM








vCenter+ ESX













vCenter + Update Manager

PXE Manager for vCenter

Neat tool to automate and provision new ESXi hosts.

Little bird tells me this feature set will be included in VSphere 5.0

PXE Manager for vCenter enables ESXi host state (firmware) management and provisioning. Specifically, it allows:

  • Automated provisioning of new ESXi hosts stateless and stateful (no ESX)
  • ESXi host state (firmware) backup, restore, and archiving with retention
  • ESXi builds repository management (stateless and statefull)
  • ESXi Patch management
  • Multi vCenter support
  • Multi network support with agents (Linux CentOS virtual appliance will be available later)
  • Wake on Lan
  • Hosts memtest
  • vCenter plugin
  • Deploy directly to VMware Cloud Director
  • Deploy to Cisco UCS blades
